I. Overview:
CXL micro-flotation sewage processor the CXL micro flotation sewage processor is a new and efficient paper machine white water, deinking pulp systems waste water and sewage treatment equipment, the device uses the most advanced micro-flotation technology, can effectively to remove suspended solids and fine suspended solids in the sewage. Suspended solids removal rate of 96% or more and can be completely clear of non-soluble COD in the sewage, is the ideal equipment for the White Water, waste paper de-inking systems and other wastewater treatment. Widely used in the paper, chemical, food, leather, industrial process water and wastewater treatment. The device has a small investment, small footprint, simple installation and construction and operation, low running costs, high Suspended solids removal and flotation removal of colloidal particulate matter.
Second, the scope of application:
This machine can be a wide range of applications and paper industry, food industry, the fiber products industry, wood processing industry, chemical industry and other sectors of the solid-liquid separation of the production process and wastewater treatment. For example, in the paper industry to be effective in white water recycling, purification of waste paper deinking project recycled water, instead of the sedimentation tanks and separation activated sludge sewage treatment.
Third, it works:
Produce large amount of dissolved gas and water preparation system, uniform, dense very fine small bubbles, the role of flocculants, intended to deal with the fine suspended solids in water, fine floc adhesion together, and make it float grew up in a collision process, mutual aggregation with gas floc formation the intergranular wrapped folder and intermediate bubble bridging adhesion inexpensive and the copolymer adhesion, so the water of the small colloidal particles and micro-flotation " to achieve the full solid-liquid separation, the purpose of purifying water; more thoroughly at the same time can still bring out the soluble COD and part of the soluble COD components.
Fourth, the characteristics of:
Aircraft equipment, compact structure, miniaturization, less area, less consumption of power; add chemicals can save 30-50% higher than the usual type; SS average penetration rate of more than 96%; discharge residue at high concentrations for more than 3%; water flow and concentration is small; on-site installation and simple construction, low cost.
V. The equipment consists of:
Host by the cylindrical and cone, the raw water inlet mixing tube, to clarify the composition of water overflow tank (or water automatic control valves), slag machines, heavy residue outlet parts are made of stainless steel (according to user needs) ; In addition, there are dissolved gas pipes, dissolved air pumps and containers such as water preparation system.
Six, the production process:
Coagulant coagulants (a) (b) scraping slag chute pulp residue or processing
(Meter) (check valve) (meter) (check valve)
The original pool of the original pump inlet mixing tube (check valve) water purifier (clarified water) overflow box back
(Or white water tower)
Heavy residue
(Regularly emissions)
Dissolved gas pipes dissolved air pumps
Gas source (air compressor)

Handling Precautions:
(1) air filters, pressure regulators, air flow meter once a good tune, basically no longer in use adjustment, each boot and run just to check and check.
(2) air filters regularly drainage.
(3) must first open the intake valve, and then immediately start the dissolved air pump, and dissolved gas pipe outlet pressure is maintained at less than the inlet pressure of 0.5 kg / square cm.
(4) regular or shutdown is sure to rinse the clarified water filter valve to prevent clogging.
(5) stable drug concentration and flow rate. Dissolving drugs (Ⅱ), must be put into slow drug particles, prevent the formation of floc.
(6) drugs (Ⅰ) corrosive, pay attention to anti-corrosion.
(7) row of each class once or regularly beat the heavy residue, when the shutdown and then boot with micro-flotation machine at the top of the water level reached the highest row of heavy residue to discharge clear liquid until (Note at the top level will not drop to overflow bottom levels).
(8) When the storage tank installation location high, stop, be sure to close the raw water into the pump valve and clarify the water discharge valve.
(9) for each month of the timing of the shutdowns, with high pressure water backwash tank internal, from top to bottom parts, and thoroughly attached to the pulp residue, Slime rinse.
(10) in each class succession, open the clarified water row trench valves, and overflow tank gate placed low, so clarify the water discharge rate immediately to speed up, purify clarify the pipes internal adhesion pulp residue to the net emission, drainage ≈ 0.5 -1 minutes.
