Filtering principle and maintenance of automated filtration equipment

A lot of customers are not sure how the new device is now filtered. What is used to filter the loop . What is the principle of work and the maintenance situation in the later stage. Today I will detail the filtration cycle principle of our automated water treatment equipment .

1. Hydraulic automation: Only the pump is the only kinetic energy in the whole system, and the pump will get energy when it is turned on.
2, no pressure system: the whole system is open without pressure, the operating energy consumption is lower than the conventional pressure system.
3. Aeration process: imitating the objective law of self-purification of water bodies in nature, through aeration, the pool water is activated and revitalized, and the immunity of the pool water is enhanced.
4, fine filtration process: through the seven-layer composite filtration layer fine filtration, fully remove organic pollution in water.
5. Prohibition of drug administration: All coagulants, coagulants, herbicides and other chemical agents are prohibited from being placed in the whole system.
6, no need to change the water: pool water recycling , a small amount of evaporated water per month, the pool water to maintain standards.
7. Automatic backwashing: When the fouling amount of the filter layer reaches the extreme value, the flow state in the filter changes, and the backwash is automatically backed up, and the dirt is automatically discharged into the sewage pipe.
8, automatic work: the whole system hydraulic automation operation, no need to special staff.
9. Energy-saving costs: The operating cost is low, and the operating cost is 20%-30% of the conventional power system.
10, long life: life expectancy of more than 30 years.

Equipment system (pump front suction or water pump rear suction) selection
1. Pump front suction system (this system is recommended system) a) The machine room ground is the same as the water level; b) the machine room ground is higher than the water level; c) the machine room ground bottom is not more than 1.2 meters in the water level.
2. Pump rear suction system (this system is more complicated than the former) a) The machine room floor needs to be 4.5 meters or more below the water level.

Later use and maintenance

1. The design area of ​​the machine room is small, and the civil engineering province

The traditional design ideas have many problems to be solved and the investment is large. Because the traditional pressure tank equipment needs to be placed underground, the design pressure tank is large, the floor space is large, the machine room is large, placed underground, bringing a series of problems such as seepage prevention, drainage, ventilation, lighting, etc., so that the cost and operation cost Increase accordingly.

Based on the principles of structure, hydraulics and physics, the company has designed and developed a new KLWT series product, which occupies less than one-fifth of the area of ​​the machine room of the traditional pressure tank system. The reason why the computer room area can be so small is because it changes the traditional design idea and no longer uses the pressure tank system. The automatic high-efficiency fine filter developed by the company has the characteristics of reasonable design and compact structure. The equipment can be placed above the ground level, so that the equipment room area is greatly reduced.

2, multi-layer fine filtration, high precision

The number of filter layers is up to seven layers, and the minimum particle size is 0.25~0.5mm, which effectively improves the dirt content and filtration precision of the filter layer, and the integrated water clarification tank makes the swimming pool circulating water treatment get rid of the investment. Adding flocculant becomes a reality. Not only greatly reduces the intensity and difficulty of the operator, but also avoids the water quality becoming an aqueous solution of flocculant (that is, the "syrup" of the swimming pool water, which is often said to be caused by excessive flocculating. The commonly used flocculants are Aluminum salt, too much will be acidic, acidic water will have adverse effects on some organs of the human body)

3, low operating costs

Not only is the initial investment reduced, but the current operating expenses are also greatly reduced, and the operating costs saved are even more substantial. The entire investment in the water treatment system can be recovered after 18 to 24 months of operation. And this all-plastic water treatment system requires no maintenance. There is no balance pool, no water pump sink, equipment can be placed above the ground level, so that the equipment room area is greatly reduced, the machine room can save hundreds of thousands of yuan.

Natural Graphite , as its name implies, is naturally formed by natural Graphite , which is generally found in graphite schist, graphite-gneiss, graphite-bearing schist and metamorphic shale.

Features

The chemical composition of graphite is carbon (C). Naturally produced graphite is rarely pure and often contains impurities, including SiO2, Al2O3, MgO, CaO, P2O5, CuO, V2O5, H2O, S, FeO and H, N, CO2, CH4, NH3, etc. Natural graphite minerals are black, steel gray, striated black; Metallic luster, crypto, dull, opaque; The hardness is isotropic, the vertical cleavage surface is 3 ~ 5, the parallel cleavage surface is 1 ~ 2; Qualitative soft, density is 2.09 ~ 2.23 g/cm3, have the feeling of greasy, easy to contaminate finger. Mineral chip under the transmitted light is generally not transparent, extremely thin can pervious to light, the light green gray, refractive index of 1.93 ~ 2.07, under the reflected light is light gray, reflective pleochroism, Ro gray with brown, Re dark blue gray, reflectivity Ro23 (red), Re5.5 (red), the reflected color, double reflection were significantly, strong heterogeneity, polarization color for straw yellow.

Graphite is a complex six-party double cone, assumes the six-party tabular crystal, common simplex are parallel double, six-party double cone, hexagonal prism, but in good condition with rare crystal forms, the generally show scaly or platy, aggregate density lump, earthy or globular.

Type

The process performance and usage of graphite is mainly depends on the degree of crystallization, in accordance with its natural Graphite Crystal morphology can be divided into crystalline graphite, Flake Graphite ) and aphanitic graphite (earthy graphite) two types of industry.

Crystalline graphite

In the crystalline (scale) graphite ore, the diameter of graphite crystals is greater than 1 mu m. Ore grade is low, but optional; The mineral associated with graphite is usually mica, feldspar, quartz, diopathic stone, diabase, garnet and a small amount of pyrite, calcite, etc., some of which have some useful components, such as rutile and vanadium. The ore is scales, grainy scales or granulocyte structures, flaky, flaky, or blocky structures.

Crystalline (scale) graphite is divided into High Purity Graphite, High Carbon Graphite, Medium Carbon Graphite and low Carbon Graphite according to the fixed carbon content.

The high purity graphite (fixed carbon content is greater than or equal to 99.9%) is mainly used for flexible graphite sealing material, nuclear graphite, instead of platinum crucible for chemical reagent melting and lubricant base material, etc.

High carbon graphite (fixed carbon content 94.0% ~ 99.9%) is mainly used for refractory materials, lubricant substrate, brush raw materials, carbon products, battery raw materials, pencil materials, filling materials and coatings, etc.

Carbon graphite (80% ~ 94% fixed carbon content) is mainly used for crucible, refractories, casting materials, foundry coatings, pencil raw materials, battery materials and dyes, etc.

Low carbon graphite (fixed carbon content 50.0% ~ 80.0%) is mainly used for foundry coatings.

Cryptocrystalline graphite

Cryptocrystalline graphite is also called soil graphite or amorphous graphite. In cryptocrystalline graphite ore, graphite crystals are less than 1 mu m in diameter, which are microcrystalline and can only be seen in the electron microscope. High grade of ore, but poor selectable; The mineral associated with graphite is often quartz and calcite; The ore is microscaly - cryptocrystalline structure, block or soil structure.

Cryptocrystalline graphite ore is mainly distributed in contact metamorphic deposits. Actually the diameter graphite flake graphite ore is uneven, the so-called crystalline graphite ore, may also contain the aphanitic graphite, are too many content is often referred to as the mixed type graphite ore, may also contain a small amount of aphanitic graphite quality mineral crystalline flake graphite piece diameter slightly larger than 1 microns.

Cryptocrystalline graphite ore is mainly used in pencil, battery, electrode, graphite emulsion, graphite bearing ingredients and the raw materials of battery carbon rod. The non-ferrous graphite is mainly used for casting materials, refractory materials, dyes and electrode paste.
