A chemical heat exchanger with an impurity treatment device

Abstract

The invention relates to a chemical heat exchanger with an impurity treatment device. The impurity treatment device is arranged on the lower side in a shell; a structure partition is arranged in the middle of the interior of the shell; a filtering and adsorbing device is inserted into the partition; and the radial section of the upper surface of the impurity treatment device is in a shape high attwo sides and low in center. According to the chemical heat exchanger with the impurity treatment device, the impurity treatment device is arranged on the lower side of the shell, so that collection and treatment of fluid are completed in one step, the process is simplified, the problems that impurities are accumulated on the shell and a liquid outlet pipe after collection to cause blocking in a traditional mode are avoided, and the fluid discharged from the heat exchanger is clean and is fully recyclable. In addition, the problem that the process in the traditional mode is complicated due tothe fact that the treatment device needs to be additionally arranged at the outer side of the heat exchanger is solved, so that the structure and the configuration are optimized by means of the chemical heat exchanger with the impurity treatment device.

Description

technical field [0001] The invention relates to the field of chemical heat exchange equipment, in particular to an impurity treatment device and a chemical heat exchanger thereof. Background technique [0002] Shell-and-tube heat exchangers are commonly used equipment in chemical process heat exchange. In the process of chemical heat exchange, due to the change of phase state, condensate often appears in the heat exchange shell or waste liquid is generated during the process. These fluids The appearance of these fluids will hinder the normal heat exchange. The treatment method for these fluids in the prior art is to set a liquid outlet at the lower end of the shell, use the lower space of the shell to temporarily store, and export this part of the fluid after a certain period of time. There is also a collection device arranged on the lower side of the housing to collect the fluid, but they all collect the fluid, and then process the fluid after it is discharged. The disadva...

AI Technical Summary

Problems solved by technology

The disadvantage of this is that after the heat exchanger has been running for a long time, due to the different types of impurities contained in the fluid in the heat exchange process, the collection device and the liquid outlet of the shell will be damaged due to the high viscosity of the fluid or the presence of more impurities. The problem of clogging in narrow places due to factors, the follow-up procedures for removing impurities from these devices are complicated, and even the heat exchange device needs to be disassembled to achieve this, which is inconvenient and not efficient enough; at the same time, because the discharged fluid contains impurities and dirt, it is necessary to install another fluid removal device after the heat exchange device is discharged, which not only takes up space, but also complicates the process
