Waste heat recycling system for semi coke production, and use method thereof

Abstract

The invention provides a waste heat recycling system for semi coke production, and a use method thereof. The waste heat recycling system comprises: a combustion furnace; a connection mechanism; a steam through pipe; a fixing mechanism used for fixing a heat exchange column and connected to a connection shell; the heat exchange column; a heat insulating wall; a driving mechanism used for driving the sliding of the connection shell and connected between the connection shell and a fixed shell; a water inlet mechanism used for continuously feeding water into the heat exchange column so as to continuously generate water vapor, arranged in the fixed shell, and connected to the heat exchange column; an installing mechanism used for fixing the heat exchange column in the installation groove on thefixed shell and connected between the heat exchange column and the fixed shell; and a sealing mechanism. The waste heat recycling system of the present invention has characteristics of high waste heat utilization efficiency, good effect, and convenient maintenance and replacement of the heat exchange column.

Description

technical field The invention relates to the technical field of semi-coke production and processing, in particular to a waste heat recycling system for semi-coke production and a use method thereof. Background technique Semi-coke is fired from the high-quality Jurassic clean coal abundant in Shenfu Coalfield. As a new type of carbon material, it has high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, The characteristics of low sulfur and low phosphorus are widely used. During the production and processing of semi-coke, it is processed through a vertical charcoal furnace. After the vertical furnace is processed, high-temperature semi-coke is produced, and semi-coke needs to be cooled to form a finished product. However, the high-temperature semi-coke produced by the traditional vertical charcoal furnace after processing the semi-coke will absorb and reuse the waste heat of the semi-coke before cooling the semi-coke. The heat a...

AI Technical Summary

Problems solved by technology

However, the high-temperature semi-coke produced by the traditional vertical charcoal furnace after processing the semi-coke, before cooling the semi-coke, the waste heat of the semi-coke will be absorbed and reused. The heat absorption efficiency of the equipment is low, the effect is poor, and in the process of using the semi-coke waste heat, the semi-coke is easy to cause damage to the heat exchange equipment after falling, but the heat exchange equipment is often installed in the insulation wall, which is difficult to find and replace, which affects the waste heat Utilization and the whereabouts of semi-coke, causing blockage in the tank
