Embodiment

[0015] Implementation example: use the shell-and-tube heat exchanger with pusher in the present invention to lower the temperature of the coke oven gas. In addition to hydrogen and methane, coke oven gas also contains coke and coal tar with a mass fraction of about 10%. The coke oven gas enters the heat exchange tube with a pusher from the material inlet pipe, and releases heat to the cooling water sprayed by the water spray device. As the temperature decreases, the coke and coal tar in the coke oven gas will continue to adhere On the inner wall of the heat exchange tube, it is pushed out by the rotating pusher. The mass fraction of coke and coal tar in the coke oven gas discharged from the material outlet pipe is only 0.1%, thereby achieving the purpose of removing coke and coal tar in the coke oven gas.

Abstract

The invention discloses a shell-and-tube heat exchanger with a stock pusher, relates to heat transfer equipment in industrial production, and belongs to the field of gas-liquid heat transfer devices. The shell-and-tube heat exchanger with the stock pusher mainly comprises a rotation mechanism (1), a tube box (5) and a heat exchange tube (9), wherein the rotation mechanism (1) drives the stock pusher (10) in the heat exchange tube (9) to rotate so as to push out liquid and solid, which are condensed on a tube wall, so blocking is avoided. The shell-and-tube heat exchanger with the stock pushercan be applied to heat transfer process in chemical industry, petrochemical industry, light industry, metallurgical industry and the like and has the characteristics of good blocking resistance, remarkable economic benefit and the like.

Description

technical field [0001] The invention relates to heat transfer equipment for chemical industry, petroleum, light industry, metallurgy and other industrial processes, specifically a shell-and-tube heat exchanger with a pusher, which belongs to the field of gas-liquid heat transfer devices. Background technique [0002] In industry, ordinary shell-and-tube heat exchangers are usually used for cooling such materials as flue gas, coke oven gas, or gas products after the reaction of certain substances (such as the reaction product of acetic acid and acetylene), but due to these materials Generally, the viscosity is relatively high and often contains solid particles, so its flow resistance in the heat exchange tube is very large and it is easy to foul on the wall surface, which will often block the ordinary shell-and-tube heat exchanger. Therefore, the heat exchanger needs to be cleaned frequently, thus increasing the maintenance time of the factory. Contents of the invention ...
