High-performance hardening-resistant distillation device

Abstract

The invention discloses a high-performance hardening-resistant distillation device, and belongs to the field of wastewater treatment. The high-performance hardening-resistant distillation device comprises a distillation tank, a stirring device, a regional temperature monitor device, an automatic controller and an automatic backflushing device. The stirring device comprises a motor, a driving shaftand a stirrer. The regional temperature monitor device comprises a temperature monitor for monitoring the temperature of the bottom wall of the distillation tank. The automatic backflushing device comprises a backflushing pump, a distillation liquid box and a backflushing pipeline extending into the distillation tank. The automatic controller is electrically connected with the temperature monitorand the backflushing pump, and is used for receiving temperature signals sent by the temperature monitor and controlling start and stop of the backflushing pump according to the temperature of the bottom wall of the distillation tank. The high-performance hardening-resistant distillation device has the advantages that distillation liquid in the distillation tank can be stirred, and backflushing can be conducted according to hardening conditions in the distillation tank to achieve a dilution effect, so that hardening is avoided, distillation efficiency is guaranteed, and maintenance cost is saved.

Description

Technical field [0001] The invention relates to the field of wastewater treatment, and in particular to a high-performance anti-caking distillation device. Background technique [0002] As a common pressure equipment, distillation tanks are widely used in chemical, petroleum, pharmaceutical, pesticide, food and other industries. It is a thermodynamic separation equipment, which uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense to separate the entire components. There are two types of unit operation processes: evaporation and condensation Union of unit operations. [0003] Distillation technology is widely used in wastewater treatment. The distillation method can volatilize the water in the wastewater in the form of water vapor to separate the water from the organic matter in the sewage and achieve the purification of the water body. However, it is easy to appear when the distilla...

[0003] Distillation technology is widely used in wastewater treatment. Distillation method can volatilize the water in the wastewater in the form of water vapor, separate the water from the organic matter and other substances in the sewage, and realize the purification of the water body. However, when the distillation tank is running, it is easy to appear The condition of hardening affects the processing efficiency and increases the maintenance cost of the distillation tank
