Abstract

The invention discloses a self-descaling evaporator. The self-descaling evaporator comprises an evaporator shell, a transmission device and a driving motor, wherein the evaporator shell is internallyprovided with a rotating inner tube, the rotating inner tube divides the evaporator shell into an inner part of the tube and an outer part of the tube, the outer side of the tube of the evaporator shell is provided with a working medium inlet, a working medium containing descaling particles is added into the evaporator shell from the working medium inlet, the outer side of the tube of the evaporator shell is further provided with a steam outlet and a working medium outlet, one end of the rotating inner tube is provided with a rotating inlet, the other end of the rotating inner tube is providedwith a rotating outlet, the steam in the evaporator shell enters the rotating inner tube from the rotating inlet via a pipeline through the steam outlet and is discharged from the rotating outlet after heat transfer, and a concentrated solution is discharged from the working medium outlet. The self-descaling evaporator has the advantages that the descaling particles are added, so that a heating tube rubs with the descaling particles, the problems of easy scale formation, blockage and sealing off of a heat exchanger are solved, and the effect of descaling is achieved; the driving motor can perform forward and backward switching, thereby capable of preventing scale formation on the reverse side of the heating tube during single-side rotation.

Description

technical field [0001] The invention relates to a self-cleaning evaporator and an operation method thereof, belonging to the technical field of environmental protection. Background technique [0002] At present, in the evaporator system provided on the market, there are two conventional designs of the evaporator: 1. The evaporator and heat exchanger are separated, and 2. The evaporator and heat exchanger are integrated. However, both of these methods use tube heat exchangers or plate heat exchangers. During use, some heat exchangers often suffer from fouling and blockage, which makes the equipment unable to operate and requires frequent disassembly, cleaning and maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-scaling evaporator, in which the heating tube is rubbed against the descaling particles by rotating to achieve the effect of descaling. [0004] The present invention is achieved through...
