Heat exchange control device for chloroethane synthesis reactor

Abstract

The invention discloses a heat exchange control device for a chloroethane synthesis reactor. The heat exchange control device for the chloroethane synthesis reactor comprises a reactor shell, a heat dissipation coil group is arranged in the reactor shell, and a control mechanism for automatically controlling the type and the quantity of introduced water is arranged between the heat dissipation coil group and the reactor shell. According to the heat exchange control device for the chloroethane synthesis reactor, by arranging a control structure of circulating water in the heat dissipation coil pipe group, the control mechanism can automatically control the entering sequence of low-pressure water for exhausting air and high-pressure water for circulation, and can input single pipelines of the heat dissipation coil pipe group one by one while controlling the sequence, so that the temperature and the reaction pressure can be better controlled.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a heat exchange control device for an ethyl chloride synthesis reactor. Background technique [0002] The ethyl chloride synthesis reactor is a relatively typical liquid-phase catalytic tower reactor. The appearance of the equipment is a vertical chemical separation tower. Because the reaction is an exothermic reaction, timely removal of the released heat is the key. Therefore, the ethyl chloride Synthesis reactors require heat exchange devices. [0003] Existing heat exchange devices mostly use coils for heat exchange, and the coils of the reactor have the function of switching hot and cold water simultaneously. When the cooling water enters the pipeline at the beginning of the system reaction, it is necessary to discharge the air through low-pressure water first to prevent water hammer. phenomenon, because when the electric water pump is started at full voltage, ...

Problems solved by technology

[0003] Existing heat exchange devices mostly use coils for heat exchange, and the coils of the reactor have the function of switching hot and cold water simultaneously. When the cooling water enters the pipeline at the beginning of the system reaction start-up, the air needs to be discharged through low-pressure water to prevent water hammer. phenomenon, because when the electric water pump is started at full voltage, it can accelerate from a static state to a rated speed in less than 1 second, and the flow in the pipeline increases from zero to the rated flow, because the fluid has momentum and a certain degree of compressibility Therefore, the sharp change of the flow rate will cause the impact of high or low pressure in the pipeline, and the phenomenon of "cavitation". The impact of pressure will force the pipe wall and generate noise, just like a hammer hitting the pipe. Known as the "water hammer effect", which seriously shortens the service life of the heat exchange device
