Evaporator for wastewater evaporation

Abstract

The invention discloses an evaporator for wastewater evaporation and belongs to the technical field of wastewater evaporators. The evaporator comprises a treatment box; a water storage frame is fixedly connected between the two sides of the inner wall of the treatment box; heating pipes are installed on the two sides of the bottom of the inner wall of the treatment box correspondingly; U-shaped grooves are formed in the bottoms of the two sides of the inner wall of the treatment box correspondingly; extrusion plates are slidably connected to one sides of the inner walls of the two U-shaped grooves correspondingly; and extrusion springs are fixedly connected to the bottoms of the two extrusion plates correspondingly. According to the evaporator for wastewater evaporation, a anti-scaling heat conduction plate is adopted, so that the heating pipes are prevented from directly contacting wastewater, and the evaporation of the wastewater is not influenced, and therefore, the surfaces of theheating pipes will not be scaled, and the normal use of the heating pipes can be guaranteed; the anti-scaling heat conduction plate can be conveniently disassembled and assembled through the arrangement of devices such as the extrusion plates and the extrusion springs, so that the anti-scaling heat conduction plate can be replaced after being used, the whole equipment does not need to be cleaned and disassembled, and the evaporator is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of waste water evaporators, in particular to an evaporator used for waste water evaporation. Background technique [0002] In view of the characteristics of chemical organic wastewater with high salt and high concentration, the wastewater evaporator adopts multi-effect reduced pressure evaporation to concentrate and crystallize organic wastewater based on the principle of evaporation, concentration and crystallization. The liquid is dried and recovered or incinerated, and the condensed water after evaporation is generally treated by subsequent biochemical treatment, which can achieve the standard of wastewater discharge. [0003] Due to the structure of the evaporator used in the general wastewater treatment process, the high-concentration solution after evaporation is prone to residues, resulting in scaling on the surface of the heating pipe, affecting the subsequent heat conduction of the heating pipe, and...
