Horizontal cooler

Abstract

The invention provides a horizontal cooler, which comprises an outer cylinder (4) and an inner cylinder (9); two ends of the outer cylinder (4) connecting a smoke inlet and a smoke outlet are provided with a connecting flange (7) and a blind plate (3); a bottom end of the outer wall of the outer cylinder (4) is provided with a water inlet pipe seat (10) and a water outlet (5); and the walls of the outer cylinder (4) and the inner cylinder (9) are provided with a shower pipe seat (6) in a mode of penetrating the walls of the outer cylinder (4) and the inner cylinder (9). The horizontal cooler adopts a double-layer circulating water cooling structure, which prevents high temperature airflow from burning out an inner wall pipe, and contacts and cools the passing high temperature airflow; thehorizontal cooler is matched with stainless steel spiral nozzles which are high temperature resistant and corrosion resistant and have good atomization; and the nozzles are arranged in a mode of multi-point crossover, and no dead angle remains, so that the high temperature airflow passing the cooler can be sprayed by water. In addition, the horizontal cooler has the advantages of small volume, low manufacturing and running cost, and easy promotion.

Description

technical field [0001] The invention relates to a cooling device, in particular to a horizontal cooler for cooling high-temperature smoke discharged from a combustion chamber. Background technique [0002] At present, the coolers used in integrated smoke and dust removal vehicles and wet ground dust removal stations generally have a horizontal structure, and high-temperature smoke and dust enter and exit in the same direction. After burning in the combustion chamber, it enters the transverse cooler through the connecting pipe, and after cooling in the transverse cooler, it is discharged into the dust collector, and then enters the high-efficiency purification dust collector to further reduce the fine particle dust, and finally dehydrates through the water separator, and enters the The emptying pipe meets the discharge standard. However, due to the physical and chemical characteristics of high-temperature smoke and dust, the currently used coolers have the following disadvan...

AI Technical Summary

Problems solved by technology

However, due to the physical and chemical characteristics of high-temperature smoke and dust, the currently used coolers have the following disadvantages: First, due to the small volume of the cooler, the cooling effect is relatively poor, and once the water pipe is blocked, the cooler will be damaged due to high temperature. Deformation can easily lead to cracks, water leakage, etc., and the equipment failure rate is high; secondly, the cooling water capacity of the cooler is not enough, and the high-temperature smoke and dust entering and leaving cannot be fully cooled. It will even burn down the dust removal system of the rear stage

However, the invention has a high cost of use, is dangerous to a certain extent when cooling high-temperature coke oven smoke, is not suitable for use, and is difficult to popularize.
