Novel anti-impact structure heat exchanger

Abstract

The invention relates to a novel anti-impact structure heat exchanger. The novel anti-impact structure heat exchanger comprises pipe plates, a heat exchange pipe, shell pass cylinders and a shell passinlet pipe, the two pipe plates are fixedly connected with the shell pass cylinders correspondingly, and a buffer cylinder is arranged between the two shell pass cylinders; the two ends of the buffercylinder are connected with the two shell pass cylinders through cone bodies correspondingly, the large ends of the cone bodies are connected with the buffer cylinder, and the small ends of the conebodies are connected with the shell pass cylinders; an inner flow guide cylinder is arranged in the buffer cylinder, the two ends of the inner flow guide cylinder are fixedly connected with the smallends of the cone bodies correspondingly, so that an annular buffer cavity is formed among the buffer cylinder, the cone bodies and the inner flow guide cylinder; a plurality of heat exchange pipes arearranged in a pipeline formed by the shell pass cylinders and the inner flow guide cylinder in a penetrating mode, and the two ends of the plurality of heat exchange pipes are connected to the pipe plates correspondingly; and a shell pass inlet pipe is arranged on the side wall of the buffer cylinder, a plurality of strip-shaped notches are formed in the back cylinder wall of the part, opposite to the shell pass inlet pipe, of the inner flow guide cylinder in parallel and are perpendicular to the heat exchange pipes. The novel anti-impact structure heat exchanger has the advantages that the impact on the heat exchange pipe is reduced, and the service life of the heat exchange pipe is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger with a highly reliable anti-shock structure. Background technique [0002] With the development of industry, the demand for energy in all walks of life is increasing day by day. In the field of chemical industry, heat exchanger, as the intermediate carrier in the heat exchange process, is an indispensable unit in the heat exchange unit. Heat exchangers play a pivotal role in chemical plants, mainly providing downstream equipment with materials at the temperature required for the process. At present, there are many types of heat exchangers in the world. According to different media, different working conditions, different temperatures, and different pressures, the selected structural types are also different. During the production process, the heat exchangers can be used as heaters, coolers, condensers, etc. There are floating head heat exchangers, fixed tube-sheet heat exchan...

AI Technical Summary

Problems solved by technology

The weld between the anti-scouring plate and the shell side of the heat exchanger will fall off, and the detached anti-scouring plate will not be tight at this time and lose its original function, and will directly hit the outer wall of the heat exchange tube with the impact of the fluid
