AI Technical Summary

Technical Problem

Existing fluidized bed coolers suffer from low heat exchange efficiency and easy leakage of heat exchange elements, resulting in short maintenance cycles, high difficulty, environmental pollution, and waste of resources.

Method used

Design a powder fluidization cooler, which adopts a structure in which heat exchange tubes inside a rectangular box are directly connected to the side wall water tank to eliminate welding points. The side wall water tank cools the side of the rectangular box and increases the heat exchange area. Horizontal and vertical baffles are set to optimize the flow of cooling water and reduce short circuits and stagnation.

Benefits of technology

It improves heat exchange efficiency, reduces leakage risk, simplifies maintenance, reduces operating costs, and improves the working environment, making it suitable for large-scale promotion.

Abstract

This invention proposes a powder fluidization cooler, comprising a rectangular box and several sets of heat exchange tubes transversely inserted into the rectangular box. A sidewall water tank, communicating with the heat exchange tubes, is located on the long side of the rectangular box, and the length of the sidewall water tank extends along the length of the rectangular box. Several air-filled boxes are located at the bottom of the rectangular box, arranged along the length of the rectangular box to supply fluidizing air. This invention reduces the problem of short-circuiting or stagnation of cooling water by setting sidewall water tanks on both sides of the rectangular box, with the heat exchange tubes inside the rectangular box directly connected to the sidewall water tanks, thus improving heat exchange efficiency. Furthermore, the sidewall water tanks, being close to the two longer sides of the sidewall water tanks, can also cool the sides of the rectangular box, increasing the heat exchange area. By transversely inserting the heat exchange tubes into the rectangular box and directly connecting and fixing them to the rectangular box, there are no welding points on the heat exchange tubes inside the rectangular box, thereby eliminating leakage points in the heat exchange elements.
