Product gas cooler

Abstract

The invention discloses a product gas cooler which comprises a shell, and a front header and a rear header which are arranged on both ends of the shell, wherein the shell defines a shell side space; the ends on both sides of the shell are respectively provided with a front tube sheet and a back tube sheet; a heat exchange tube is fixed between the front tube sheet and back tube sheet; the front header defines a tube side space communicated with the heat exchange tube; a scour-protection wear-resistant distributing plate opposite the front tube sheet is arranged in the front header; the scour-protection wear-resistant distributing plate is provided with a plurality of mounting holes; and one end of the heat exchange tube extends into the tube side space and is fixed with the mounting holes. The scour-protection wear-resistant distributing plate is adopted to reduce the abrasion of the high-hardness catalyst to the tube sheets, thereby protecting the liners of the tube sheets and also protecting the tube head.

Description

technical field [0001] The application relates to a product cooler, which is especially suitable for coal chemical industry, fine chemical industry, oil refining, pharmaceutical, refrigerant and other industries. Background technique [0002] Coal chemical industry refers to the chemical process that uses coal as raw material and converts coal into gas, liquid or solid raw materials or products through chemical processing, which mainly includes coal gasification, liquefaction, hydrogenation, catalysis, cracking, fractionation, Purification, separation, washing, etc. There are heating and cooling or condensation processes in these processes, especially after gasification or reaction. Because the process of gasification and reaction is more complicated, catalysts are often added in this process. There are many types of these catalysts, including metal Non-metallic, especially those with high hardness, and these reactions are often high temperature and high pressure, but the p...

Problems solved by technology

[0003] Due to the large-scale production of coal chemical industry and chemical industry, the size of the equipment is also increasing. How to make the product gas cooler run efficiently and safely is an important task for process expansion and equipment safety. The product gas cooler is in the domestic market. The coal chemical industry basically relies on imports, and the coolers in other industries basically have low operating efficiency. It is not the problem of the tube plate and heat exchange tube head at the import end, or the design size is too large, resulting in waste. At the same time, the product gas in other industries The cooler also has certain limited use, which brings hidden dangers to safe production. How to make the product air cooler work better has become a new research topic today.
