Abstract

The invention discloses a forced-circulation fixed tube sheet type evaporator, which comprises a barrel and at least one expansion joint, wherein the at least one expansion joint is arranged on the barrel; a plurality of cross baffles which are distributed in a staggering manner are arranged inside the barrel at intervals up and down; the cross baffles are correspondingly provided with a plurality of through holes; pipe spacers and pull rods are arranged in the through holes in an insertion manner; a plurality of separating plates are arranged in a cavity, near a bottom end, of the barrel; the bottom end of the barrel is provided with a plurality of emptying openings; one side, near a top end, of the barrel, is provided with a medium inlet; the other side, near the top end, of the barrel is provided with a medium outlet; a liquor condensate inlet and a liquor condensate outlet are arranged above the medium inlet and the medium outlet. The-forced circulation fixed tube sheet type evaporator is simple and compact in structure, can bear higher pressure and is low in manufacturing cost; a tube pass is cleaned conveniently; a tube is easily blocked or replaced when being damaged. The heat transfer efficiency is high; the evaporation capacity is large.

Description

Technical field [0001] The invention relates to the transformation of heat exchanger equipment, which is mainly used in evaporation crystallization equipment. Background technique [0002] Heat exchangers are universal process equipment widely used in many industrial sectors. Generally, in the construction of chemical plants, heat exchangers account for about 11% to 40% of the total investment. Its advancement, rationality and operational reliability will directly affect the quality, quantity and cost of products. The heat exchangers of the prior art are prone to tube blockage and fouling, and need to be improved. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the present invention provides a forced circulation fixed tube plate evaporator with a simple structure, effectively improving heat transfer efficiency, effectively preventing tube blockage and fouling, and preventing thermal deformation. [0004] In order to achieve the purpose of the presen...
