Embodiment Construction

[0016] See figure 1 , a method for recovering the waste heat of coke oven raw gas, the method is to transform the coke oven riser 1, install a semiconductor thermoelectric power generation module 2 on the outer wall of the riser 1, and recover the waste heat of coke oven waste gas to generate electricity.

[0017] Improve the refractory bricks of the riser, use silicon carbide refractory lining bricks to replace the original refractory lining bricks, install the semiconductor thermoelectric power generation module 2 on the outer wall of the riser 1, and use the raw coke oven gas in the riser 1 as the heat of the semiconductor thermoelectric power generation source, to realize waste heat recovery of coke oven raw gas in the rising pipe. Since the thermal conductivity of silicon carbide refractory lining bricks is higher than that of refractory lining bricks, the heat of coke oven raw gas can be quickly transferred to the wall of riser 1, so riser 1 becomes the heat collector of...

Abstract

The invention relates a method and a device for recovering the waste heat of a coke oven crude gas. In the method, the refractory lining bricks of a riser are improved by using silicon carbide refractory lining bricks, a semiconductor temperature difference power generation module is arranged on the outer wall of the riser so as to use the coke oven crude gas in the riser as the heat source of a semiconductor temperature difference power generator, the riser serves as the heat collector of for semiconductor temperature difference power generation, and the waste heat recovery of the coke oven crude gas in the riser is realized. The method and the device of the invention have the advantages that: 1) the problem of recovering the waste heat of the coke oven crude gas in a coking process is solved; and 2) when the method and the device are used, the waste heat carried by the coke oven crude gas can be recovered for generating power and cooling hot water flowing out from a channel and for civil or industrial heating, cooling and heat production for saving energy and improving energy efficiency.

Description

technical field [0001] The invention relates to a method and device for recovering waste heat of coke oven raw gas. The principle is to transform the rising pipe of coke oven, install a semiconductor temperature difference power generation module on the outer wall of the rising pipe, and recover the waste heat of coke oven raw gas to generate electricity, which belongs to industrial waste heat Recycling application technology field. Background technique [0002] The coking process is an energy conversion process, and there is a large amount of waste heat utilization space in the conversion process. Whether it is solid, gaseous, or liquid products, there is a large amount of industrial waste heat to be recovered. Realizing the recovery and utilization of these waste heat will generate great social and economic benefits. Coal produces a large amount of high-temperature raw gas during high-temperature carbonization in coke ovens. The temperature of raw gas is about 800°C. After...
