Problems solved by technology

The problem is that after adopting such a high-energy consumption forced circulation pump, although the inner wall of the heating tube can be washed with the help of crystals suspended in the solution, the speed of scaling can be slowed down and the cycle of parking cleaning can be prolonged, but it still cannot fundamentally solve the problem of crystallization. The fundamental problems of periodic parking cleaning, high energy consumption and low efficiency of evaporation production caused by salt scale

Abstract

The invention discloses a surfing cleaning type reverse natural circulation evaporator, which is composed of a surfing head, a conical compression spring, a cleaning screw and a nozzle seat to form an automatic cleaning mechanism. The surf head is the power head of this self-cleaning mechanism, effectively utilizing the powerful power provided by the surf current at the top. The cleaning spiral is not only a convective heat transfer enhancement element, but also an automatic cleaning element. During production and operation, the surfing head drives the cleaning screw to produce 6-15 times per minute of large reciprocating motion of 30-60mm up and down and low-speed rotation motion to clean the crystallized salt scale on the inner wall of the heating tube evenly and effectively, so as to achieve stability and high efficiency The purpose of long-term continuous production and significant increase in production and energy saving.

Description

technical field [0001] The invention relates to a surf cleaning type reverse natural circulation evaporator, which relates to the enhancement of convective heat transfer in the heating tube of the reverse natural circulation evaporator and the automatic cleaning of salt crystal scale. It is mainly suitable for evaporators and evaporative crystallizers of solutions to crystallize salt scale under positive and normal pressures. Background technique [0002] As we all know, high-salt solution evaporators are very prone to salt scaling. After the salt scale builds up in the heating tube, the energy consumption increases significantly and the production capacity decreases, so it is forced to stop for cleaning, which seriously affects the efficiency of evaporation production. For this reason, forced circulation evaporators are mostly used for high-salt solutions, and the flow rate in the heating tube is generally designed to be above 2 (m / s). Large circulating pumps with large f...
