A rectangular block graphite heat exchanger for hydrochloric acid production

Abstract

The invention discloses a rectangular block-type graphite heat exchanger for hydrochloric acid production, which comprises a heat exchanger mechanism. Both sides of the bottom end of the heat exchanger mechanism are fixed with support seats, and one side of each support seat is A fixed plate is fixed, the tops of the left and right ends of the heat exchanger mechanism are fixed with condensed water outlets, the middle part of one side of the heat exchanger mechanism is installed with a liquid displacement mechanism, and the bottom of one side of the heat exchanger mechanism is A condensed water inlet is fixedly installed, and one end of the condensed water inlet is equipped with a water purification mechanism, and the other end of the condensed water inlet is fixedly connected with one end of the liquid guiding head; the present invention is connected with a liquid driving mechanism and a The blocking mechanism, after the condensed water enters the heat exchanger, the driving mechanism drives the condensed water to rotate in the heat exchanger, and at the same time, the blocking mechanism can block the flow of the condensed water to prevent it from rising rapidly, which can effectively improve The frequency of entering and exiting the transverse holes of the graphite heat exchange block improves the heat exchange performance of the heat exchanger and ensures the production of hydrochloric acid.

Description

technical field [0001] The invention belongs to the technical field of graphite heat exchangers, in particular to a rectangular block graphite heat exchanger for hydrochloric acid production. Background technique [0002] Graphite heat exchangers are divided into block-hole type, shell-and-tube type and plate type according to the structure, and have the characteristics of good corrosion resistance and good heat transfer performance. Graphite heat exchangers can be used for production and heat exchange of corrosive media such as hydrochloric acid, sulfur, acetic acid and phosphoric acid. [0003] While the existing rectangular block graphite heat exchanger for hydrochloric acid production is in use, the condensed water enters the heat exchanger, passes through the material into the longitudinal hole of the graphite heat exchange block, and the condensed water enters the transverse hole of the graphite heat exchange block. To achieve the purpose of heat exchange, but in this...

Problems solved by technology

[0003] While the existing rectangular block graphite heat exchanger for hydrochloric acid production is in use, the condensed water enters the heat exchanger, passes through the material into the longitudinal hole of the graphite heat exchange block, and the condensed water enters the transverse hole of the graphite heat exchange block. To achieve the purpose of heat exchange, but in this process, the condensed water rises too fast, there is no blocking mechanism, and the condensed water cannot rotate in the heat exchanger, and there is no liquid driving mechanism, which will cause condensed water to enter and exit the graphite heat exchange block The frequency of transverse holes is reduced, resulting in a decrease in the heat transfer performance of the heat exchanger and affecting the production of hydrochloric acid. At the same time, there is no water purification mechanism before the condensed water enters the heat exchanger, which will cause impurities and scale in the condensed water to enter the heat exchange. In the heat exchanger, too many impurities are accumulated in the heat exchanger, which affects the heat exchange effect of the heat exchanger. At the same time, it is difficult for personnel to clean the heat exchanger, which is not conducive to the use of personnel.
