High concentration sewage accelerated evaporation equipment

Abstract

The invention relates to high-concentration sewage accelerated-evaporation equipment which comprises a support frame and a water distributing device, wherein the water distributing device comprises a housing, a dual-output-shaft motor is arranged in the housing along a longitudinal axial line of the housing, a fan is arranged on a first output shaft of the dual-output-shaft motor, and a crushing impeller is arranged on a second output shaft of the dual-output-shaft motor. According to the high-concentration sewage accelerated-evaporation equipment provided by the invention, over-saturated high-concentration sewage is crushed into super fine particles by virtue of the high-speed rotating crushing impeller, and the super fine particles are sent into air by virtue of the fan for evaporating. By adopting a crushing and atomizing manner in the invention, a mechanical crushing and atomizing manner is used for replacing a high-pressure pump nozzle spray-atomizing manner, so that the evaporation cost is lowered, and the defects such as sewage blockage, scaling formation and corrosion of a nozzle are prevented.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an accelerated evaporation equipment for high-concentration sewage. Background technique [0002] In recent years, more and more attention has been paid to the waste water and circulating cooling sewage generated in industrial production processes such as electric power, metallurgy, oil refining, and coal chemical industry. With the continuous increase of the cost of water resources and the strengthening of the state's control over corporate sewage discharge, sewage reuse technology has been widely popularized. During this process, a small amount of concentrated brine must eventually be discharged from the treated sewage, which contains high concentrations of ions and organic matter. At present, there are mainly the following two solutions for the treatment of this part of high-concentration sewage: first, use evaporation and crystallization, use the waste heat or waste heat inside ...

AI Technical Summary

Problems solved by technology

Both of the above two methods have advantages and disadvantages: the first method is the most thorough treatment of high-salt wastewater, and the relative technology is relatively mature. The disadvantage is that the treatment cost is too high, and a large amount of steam is required in the process. More than ten yuan, it is impossible to deal with a large amount of high-salt water, and the evaporation and crystallization reaction equipment has high requirements on materials, resulting in a large one-time investment; the atomization evaporation devices in the second method are all in the form of nozzles, such as CN203639184U and In the evaporator described in CN203389343, the high-concentration sewage is sprayed through the atomizing nozzles. Since the diameters of the spray outlets of the nozzles are very small, the high-concentration salt in the high-concentration sewage is easy to accumulate in the nozzles, causing blockage to the nozzles. The rapid corrosion of the nozzle will cause the evaporation equipment to be scrapped soon after use, and due to the blockage of the nozzle by the dirt, the spray efficiency of the evaporation equipment will be reduced and the evaporation speed will be reduced
