Abstract

The invention provides a recovery device for chemical waste liquid. The recovery device for chemical waste liquid comprises a heater, an evaporator, a condenser and a liquid sealing tank which are connected in sequence, wherein the upper part of the heater is provided with a feed inlet; the bottom outlet of the evaporator is connected with a discharging pump; a small condensate buffer tank is connected to the condenser; and the heater, the evaporator and the condenser are all provided with temperature sensors and pressure sensors. The recovery device for chemical waste liquid further comprisesa water ring pump unit for vacuum pumping; and the device uses a PLC automatic control system. The recovery device has the beneficial effects that the device is obtained based on reconstruction of existing equipment, and is low in operation and running cost; the waste liquid evaporation device has high evaporation efficiency, is simple to operate, and adopts a full negative pressure system to ensure clean and safe production and reduction in environmental pollution; the recovery device adopts the PLC automatic control system, so operation is safe and simple, the amount of condensate is reduced, and good recycling effect of cooling water is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial waste liquid recovery, in particular to a chemical waste liquid recovery device. Background technique [0002] In modern industrial production, if untreated waste liquid is discharged randomly, it will not only have a bad impact on the environment, but will even destroy the ecology and cause a waste of resources. How to effectively treat industrial waste liquid has gradually gained the attention of more and more industrial production enterprises, and the waste liquid treatment device has been continuously improved. [0003] In the prior art, negative pressure concentration and evaporation process is mostly used for the treatment of industrial waste liquid. The principle of negative pressure evaporation is to heat the aqueous solution containing metal salts and hydrogen chloride solutes in a vacuum state, so that the soluble solutes and water in the solution evaporate together, and condense wit...
