High-efficiency low-resistance heat tube afterheat recycling device

Abstract

The invention discloses a high-efficiency low-resistance heat tube afterheat recycling device and belongs to the technical field of afterheat utilization of the coal chemical industry. The high-efficiency low-resistance heat tube afterheat recycling device consists of an evaporation work section and a condensation work section, wherein a liquid storage chamber is arranged between the evaporation work section and the condensation work section; the evaporation work section comprises a carbonization chamber; a membrane type evaporation pipe is arranged inside the carbonization chamber; semi-coke entering the carbonization chamber falls on the upper surface of the membrane type evaporation pipe; the condensation work section comprises a corrugated condensation pipe; the upper end of the corrugated condensation pipe is connected with the upper end of the membrane type evaporation pipe via a steam pipe; the lower end of the corrugated condensation pipe is connected with the upper end of the liquid storage chamber via a connecting pipe; the lower end of the liquid storage chamber is connected to the lower end of the membrane type evaporation pipe via a condensate reflowing pipe. The high-efficiency low-resistance heat tube afterheat recycling device has the advantages of being high in heat transmission efficiency, flexible in long-distance arrangement, energy-saving, environment-friendly, safe and reliable, and is capable of effectively solving the problems of environmental pollution, poor coke quenching effect and low semi-coke afterheat recovery efficiency caused by water cooling quenching and steam quenching.

Description

technical field [0001] The invention belongs to the technical field of waste heat utilization in coal chemical industry, and relates to a high-efficiency and low-resistance heat pipe waste heat recovery device. Background technique [0002] The use of waste heat in factory production for urban heating is a key area of ​​exploration in the "13th Five-Year Plan" national development strategy. Semi-coke enterprises are the pillar industries in Yulin, Inner Mongolia, and Shanxi. The coal in these areas is bituminous coal. They are dry-distilled in the carbonization furnace to form semi-coke, and then sent out from the coke discharge port. Since the temperature of the semi-coke leaving the carbonization furnace is as high as 500°C, it needs to be cooled to 60°C for easy stacking and transportation. In the earliest semi-coke production, water seals were used to cool down the temperature, and the coke quenching wastewater was seriously polluted because it contained a large amount ...

AI Technical Summary

Problems solved by technology

However, the improved coke quenching process has the problems of discontinuous water spraying and easy clogging of the nozzle holes, requiring a lot of on-site maintenance and labor

Although there are currently technologies that use heat pipes to recover the waste heat of the semi-coke quenching, there is still a lack of effective technical measures for how to realize the operation of high-efficiency and low-resistance heat pipe devices.
