Abstract

The invention discloses an automatic-cleaned high-concentration waste liquor drying device and a use method therefor. The drying device comprises a charging unit, an evaporative crystallization unit,an evaporative purification unit, a vacuum unit and an automatic control unit which are sequentially connected, wherein the evaporative crystallization unit at least comprises a tubular shell body, anautorotatable main shaft is coaxially arranged inside the shell body, a group of combined scrapers which synchronously rotate along with the main shaft are arranged on the main shaft in an annular manner, the shell body and the evaporative purification unit communicate with a cleaning unit through pipelines, the cleaning unit at least comprises a cleaning water tank and a cleaning centrifugal pump, the cleaning water tank is at least connected with one dosing tank, and the automatic control unit can control the cleaning unit to automatically start up the cleaning water tank and/or the dosingtank for clean water cleaning and/or agent cleaning. According to the automatic-cleaned high-concentration waste liquor drying device and the use method therefor, disassembly-free online cleaning canbe carried out by using clean water or preparing a detergent, and thus, the evaporative crystallization unit and the evaporative purification unit can maintain efficient drying operating efficiency.

Description

technical field [0001] The invention relates to the technical field of high-concentration waste liquid treatment, in particular to an automatic cleaning type high-concentration waste liquid drying device and a method for using the same. Background technique [0002] Zero discharge of industrial waste liquid is a problem that enterprises must solve. The treatment of high-concentration waste liquid is the last link in the treatment of zero discharge of industrial waste liquid. At present, mainstream energy-saving evaporation equipment such as multi-effect evaporation and MVR evaporation equipment can remove some specific content Salt waste liquid is evaporated and crystallized to achieve the goal of zero discharge, but inorganic salt waste liquid with complex components, waste liquid containing organic impurities, and mixed waste liquid are easy to The operation of the evaporation equipment fails, and the purpose of treatment cannot be achieved through conventional evaporation...
