Chemical degreaser

Square chemical degreaser

Long chemical degreaser

First, the product description
Chemical degreasing method is to add chemical \ by mixing the reaction of water in the oil \ iron oxide skin and other suspended solids, by coagulation \ flocculation settling separation, to purify the water quality purposes, when the water in the oil 35-45mg / 1 or so, its effluent oil is below 10mg / 1, SS content below 25mg / 1.
Add a total of two kinds of agents, separate dosing, the first is an electrolyte agent, into the first mixing chamber; the second is a special polymer flocculant, into the second mixing chamber, the first cast first Pharmacy, the second vote after the injection of drugs, and the dosing order can not be reversed. Two drugs evenly non-toxic harmless agents. After dosing and can be mixed after the first \ second mixing chamber of sewage into the inclined tube precipitation, the water Oil (slick and emulsified oil) and suspended solids by coagulant \ flocculation role, the shape of large particles of flocculation subsidence in the lower discharge mud bucket, the upper part of the water through the overflow weir \ outlet pipe. The lower part of the sludge can be periodically discharged , Usually 8 hours row, each time 2-3 minutes.Expelled sludge can be discharged to the cyclone tank (or a metal deposition tank) slag pit and coarse iron together shipped, but also a separate filter press for recycling .
MHCYG series chemical degreaser is the second generation of CYCW chemical degreaser, the second generation of products compared with the first generation of products Advantages:
1, a little less efficient processing. MHCYG type chemical degreaser can accumulate the sludge in the equipment settling tank to circulate and flow with each other as much as possible in the raw water (fine iron oxide scale) and oil (slick and emulsified oil) Give full play to the role of throwing agent to improve the processing efficiency and processing effect.
2, a little lower operating costs. First, give full play to the medicine, can save dosage of medicine; the second is to reduce the power consumption. Compared with the first-generation chemical degreaser, it can save more than 30% dosage of medicament and reduce the energy consumption by more than 50%, saving a considerable cost.
3, stable operation, adapt to the performance of strong. Due to the large equipment volume, engage in equipment, water impact (water hours when large). and part of the sewage backflow in the equipment, increased pesticide collision in the sewage, the chance of adhesion. Accelerated the suspended solids and oil flocculation settling velocity, the treatment effect is stable and reliable, the treatment effect is thorough.
4, management more convenient. CYCWG series of chemical degreaser to change the past multi-bucket mud as a single bucket of mud, and mud bucket volume, sludge cycle regulation is also large. Mud reflow can be adjusted, just lift the impeller device can be until the set to the best position.
The new technology of oily wastewater chemical degreasers of steel enterprises reached the top priority of the leaders of the Ministry of Metallurgy and was identified by the Ministry of Metallurgy in May 1996, leading the country in its advanced technology.
MHCYG-type chemical degreasing series of development and application of steel to the oil-water sewage treatment to solve the problem, at present, many steel companies in the country widely used, by the unanimous welcome.

Second, the main features
MHCYG efficient degreaser decontamination device fouling device set reaction, precipitation, mud in one, all using modern electric control, simple operation, no secondary pollution.
The device uses double-deck mixer paddle, the motor cycloid reducer, easy to use, durable, mixed, Reynolds number reached 108 or more.
Electrical system uses PLC double-lock self-defined function, the performance is more stable and reliable, and leave the remote centralized monitoring of the necessary interfaces and signals.
Oil flocculant is an anionic polymer flocculant, with strong flocculation capacity, high efficiency of oil removal and suspended solids, easy to use, low cost, low operating cost (0.026 yuan / ton of sewage), non-toxic, etc., Good scale, corrosion inhibition.
The device uses high-quality Ф50 PVC hexagonal honeycomb packing, the thickness of 0.6mm, greatly increased the settlement area, inclined pipe area upflow rate (4.1mm / s,) so that the water suspension can naturally sedimentation in the inclined pipe channel surface, and then accumulate into a certain Weight slipped in the sludge hopper.
The chemical degreaser based on shallow pool precipitation principle, through a single inclined pipe (H = 1000mm) technology, greatly increased the settlement area, making the load up to 4m3 / m2.h, so the device handling large amount of water and small footprint.
