Background technology
The main component of crystal silicon cutting waste mortar is cutting liquid component, carborundum, silica flour and metal impurities, and above-mentioned all kinds of components are mingled in and become pasty material together.Resource recovery through waste mortar obtains respective resources property component, obtains the resource regeneration product through deep processing again, is an industry focus in the present domestic photovoltaic cutting auxiliary material industry.
Crystal silicon cutting waste mortar is after Separation of Solid and Liquid, and main component is a silicon carbide micro-powder in the carbonization silica sand material, includes a certain amount of cutting liquid component, silica flour and metal impurities simultaneously.Common, the purification schemes of above-mentioned carbonization silica sand material is comprised that alkali cleaning removes silica flour, pickling and remove metal impurities and clear water and clean etc., corresponding, can produce a large amount of alkali cleaning waste water, pickling waste waters and washing waste water in this course.In actual production process, inevitably can be rich in a certain amount of suspension in the above-mentioned washes, generally speaking, its SS content can be between 4000-100000.On the one hand, in the wastewater treatment process, the SS index is important control index; On the other hand, the main component of suspension is a silicon carbide micro-powder, still has the important resource value.
The utility model content
The purpose of the utility model provides a kind of environmental protecting device of removing suspension in the carbonization silica sand material washes.In actual application, Sewage Disposal is at first removed the PROCESS FOR TREATMENT of suspension to the washes of carbonization silica sand material, treat to carry out follow-up biochemical treatment again after SS content reduces significantly in the waste water.
For realizing above-mentioned purpose, the solution of the utility model is: a kind of environmental protecting device of removing suspension in the carbonization silica sand material washes is characterized in that it is made up of sedimentation basin, clean solution tank, precipitating reagent batching dropping jar, sewage transport pump, filter press; Said sedimentation basin is the subsidiary sand material delivery pipe in body bottom in the pond; Said precipitating reagent batching drips jar and through bottom discharge precipitating reagent is rendered in the sedimentation basin; Said sewage transport pump is transported to sewage clean solution tank and sewage is transported to subsequent handling from clean solution tank from sedimentation basin; Subsidiary filter residue delivery pipe of said filter press and filtrating discharge nozzle, it is separated into filter residue and pressing filtering liquid with the sand material press filtration that the sand material delivery pipe of sedimentation basin transports.
The all subsidiary discharging valve plate of said sand material delivery pipe, filter residue delivery pipe.
Said pressing filtering liquid is transported to clean solution tank through the filtrating discharge nozzle through the fluid pump.
Said filter residue is collected through the filter residue delivery pipe, and main component is a silicon carbide micro-powder, can carry out resource again and reclaim.
The advantage of the utility model: the utility model device has the function of removing suspension in the carbonization silica sand material washes, reduces SS content in the washes significantly, so that follow-up sewage treatment process; Simultaneously, suspension (main component is a silicon carbide micro-powder) can carry out the resource recovery again through collecting.
To combine accompanying drawing that the utility model is described in further detail below.
