Rocker deashing plate cooler

Abstract

The invention relates to a rocker deashing plate cooler. The rocker deashing plate cooler comprises an upper box (1) and a lower box (2), wherein the upper box (1) and the lower box (2) are divided into a left part and a right part through a clapboard (18) which is located between the upper box (1) and the lower box (2); multiple lines of cooling units (7) penetrate through the left and right parts of the lower box (2) along the forward and backward directions; the left and right sides of each line of the cooling units (7) are provided with a deashing chain (6) respectively; the upper box (1) is provided with a deashing chain transmission mechanism (5); the deashing chain transmission mechanism (5) comprises an oscillating bar mechanism (5.2); the deashing chain (6) is arranged on the oscillating bar mechanism (5.2); the oscillating bar mechanism (5.2) can drive the deashing chain (6) to swing forward and backward, so as to perform a deashing operation on the external surfaces of the cooling units (7). The rocker deashing plate cooler provided by the invention is good in heat transfer effect, ideal in deashing effect and convenient in maintaining and replacing a cooling element.

Description

Technical field [0001] The invention relates to a rocker ash cleaning plate type cooler, which is mainly used for cooling high temperature flue gas in oil refining, petroleum, chemical, metallurgical and other industries, and belongs to the technical field of cooling equipment. Background technique [0002] The temperature of the flue gas at the end of the non-ferrous metal smelting kiln is generally 700~1000℃. The flue gas temperature must be cooled to 150~350℃ before entering the kiln tail fan and dust collection device, otherwise it will cause damage to the dust collection equipment. The currently widely used straight-through flue gas cooler generally adopts a round tube structure for its cooling elements. Smoke and dust can easily block the cooling elements during production and use. After a period of use, the heat exchange effect is poor. When the heat exchange elements are damaged, maintenance and replacement are also necessary. Very inconvenient. Moreover, the method of c...

AI Technical Summary

Problems solved by technology

[0002] The flue gas temperature at the tail end of a non-ferrous metal smelting kiln is generally 700~1000°C. Before entering the kiln tail fan and dust collection device, the flue gas temperature must be cooled to 150~350°C, otherwise it will cause damage to the dust collection equipment.

The straight-through flue gas cooler commonly used at present generally adopts a circular tube structure as the cooling element. During production and use, the smoke and dust are easy to block the cooling element, and the heat exchange effect is poor after a period of use. When the heat exchange element is damaged, maintenance and replacement are also necessary. Very inconvenient

Moreover, the dust removal method generally adopts manual dust removal or pneumatic dust removal. The dust removal process needs to stop production, and the dust removal effect is very unsatisfactory.
