[0002] Tubular heat exchangers are often used in chemical production as temperature control equipment for materials. They are a type of heat exchanger, mainly composed of a shell, a tube bundle, a tube sheet and a head. During use, two different fluids can circulate to control the temperature of the two flows. Baffles are usually installed inside the heat exchanger to prevent short circuits when the fluid circulates inside. After long-term use, there will be a certain amount of attachments composed of impurities accumulated inside, which affects the heat exchange treatment under the liquid circulation state.

[0003] The shell and tube heat exchanger in the prior art generates sewage containing a large amount of microorganisms, flocs, colloids, floating and suspended solid particles during heat exchange work. Therefore, during the use of the heat exchanger, dirt precipitation and scaling often occur on the sewage side of the heat exchange tube bundle, which increases the heat transfer resistance of the heat exchanger, seriously affecting the heat exchange effect and reducing the work efficiency. It also causes damage to the heat exchanger, increases maintenance costs, and reduces the service life of the heat exchanger. To this end, we propose a shell and tube heat exchange equipment that is easy to clean. Utility Model Content
