Mud processes disposal application technology as the second resource and starts late, although have been carried out bigger progress, but for carwash Treatment of Sludge
Effective technology is in conceptual phase, especially lacks flocculant and carwash mud high efficient mixed technical method, and carwash mud is wadded a quilt with cotton
Solidifying processed is relatively costly, and flocculant usage is relatively big, effect and inefficient.
Summary of the invention
The present invention is relatively big with carwash sludge flocculation dehydration technique method flocculant usage in order to solve existing flocculant, place
Manage relatively costly, flocculation dewatering effect and inefficient problem, it is provided that a kind of flocculant cleans, with motor vehicles, the side that mud mixes
Method.
Flocculant of the present invention cleans, with motor vehicles, the method that mud mixes, and sequentially includes the following steps:
One, the atomization of liquid flocculant: use soniclizer to carry out atomization liquid flocculant and be processed into vaporific wadding
Solidifying agent, if flocculant is solid-state, first carries out being dissolved as liquid solution with clear water, then uses soniclizer to carry out at atomization
Reason；
Two, vaporific flocculant mixes with air: the nozzle of soniclizer is placed in the static state connected with air and mixes
In clutch, make vaporific flocculant mix with air at ambient pressure, obtain the mixture of vaporific flocculant and air；
Three, mixture step 2 obtained uses gas-liquid mixing pump pressurization to mix with containing water car-washing mud.
Further, in step one, the ultrasonic frequency of soniclizer is 30-50kHz.
Further, in step 2 vaporific flocculant with air by 1:(48～52) volume ratio mix.
Further, the mixture that step 2 obtains is mixed by the volume ratio of 1:10 with containing water car-washing mud.
Beneficial effects of the present invention:
It is high that carwash mud is mainly characterized by moisture content, difficult dehydration.Flocculant is converted to liquid by the present invention, then to liquid
State flocculant applies ul-trasonic irradiation and is atomized, and liquid flocculant is dispersed as (several microns to 100 microns) fine particle
Be injected in air connect static mixer in, make vaporific flocculant be mixed into air at ambient pressure vaporific flocculant and
Air mixture, nebulization efficiency is high, and energy consumption is low.Vaporific flocculant and air mixture are sucked by gas-liquid mixing pump air entry,
After the pressurization containing water car-washing mud sucked with liquid sucting port in the pump housing mixes, it is pumped in air flotation slot so that flocculant is dirty with carwash
Mud mix homogeneously is abundant, relatively uses stirring-type mixing in traditional flocculation tank, saves flocculation space, and shorten the time, improve
Sludge flocculation effect, can reduce flocculant usage, simultaneously facilitates the raising of dewatering rate, reduces processing cost, is conducive to washing
Car sludge reduction, stabilisation, innoxious, recycling.
