Abstract

The invention proposes a solid particle cooler, which is characterized in that water or heat-taking medium enters the main unit, steam-water or heated medium flows out from the unit, heat-taking unit, water or heat-taking medium secondary enters the unit, steam-water or heated medium It is composed of auxiliary medium outflow unit, water or heat-taking medium inlet pipe, steam-water or heated medium heat exchange sleeve, etc. Partitions are respectively set inside the water or heat-taking medium main inlet unit and steam-water or heated medium main outflow unit, and are separated from the outside There is a one-to-one correspondence between the inlet of water or heat-taking medium and the outlet of steam-water or heated medium. A catalyst inlet, fluidization gas inlet and distributor are set in the heat-taking unit, and a replacement unit for catalyst-carrying gas can be set under the heat exchange tube. ; Water or heating medium auxiliary entry unit and steam water or heated medium auxiliary outflow unit can be used as a separate partition or divided into several small areas by partitions. In order to solve the problems that the heat exchange tube bundle of the existing solid particle cooler is inconvenient to repair and replace, the use of pipelines and valves is large, and the operability is not strong.

Description

technical field

[0001] The invention relates to a solid particle cooler in the technical field of heat exchange, in particular to a heat extraction or solid particle cooler suitable for gas-solid fluidized bed reaction process. Background technique

[0002] During exothermic reaction processes such as catalytic cracking regeneration, fluidized bed methanol to olefins, and fluidized bed methanol to aromatics, it is necessary to take out part of the heat or cool solid particles such as catalysts to obtain heat. A solid particle cooler is usually used to absorb this part of excess heat to ensure the smooth operation of the process. At the same time, the solid particle cooler also uses this part of excess heat to generate steam or heat other media, which has become an important energy-saving measure in the device. Solid particle coolers are widely used in industry due to their large heat gain and easy operation.

[0003] There are many types of existing solid particle coolers....
