Description

Chemical reaction product heat exchanger

Technical Field

The utility model relates to the technical field of chemical reaction equipment, in particular to a chemical reaction product heat exchanger.

Background

During the alkylation reaction, a heat exchanger is needed, and the heat exchanger heats the feed and increases the temperature to adapt to the process conditions of the alkylation reaction. Meanwhile, heat energy after alkylation reaction can be recovered through heat exchange, so that energy consumption is saved.

The conventional shell-and-tube heat exchanger structure has the following disadvantages: 1. a plurality of baffle plates are arranged between the tube and the shell in the traditional shell-and-tube heat exchanger, and in the heat exchange process, certain heat loss can occur due to the fact that the baffle plates between the tube and the shell have resistance to the flow of hot materials, so that the heat exchange efficiency is low; 2. the shell of traditional shell-and-tube heat exchanger is the individual layer, and after the hot material got into in the shell, the hot material can carry out the heat exchange with external environment equally, and lead to heat loss, reduce heat exchange efficiency.

In summary, a chemical reaction product heat exchanger with higher heat exchange efficiency is needed at present.
