Abstract

The invention provides a distributed utilization method and a utilization system of coking waste heat, and relates to the technical field of waste heat utilization in the coking industry. The distributed utilization method of the coking waste heat comprises the following steps: firstly, converting the coking waste heat into gas and installing a heat exchanger on a waste heat gas pipeline; then enabling heat conduction oil to enter the heat exchanger for absorbing the heat in the waste heat gas to obtain heat conduction oil A; supplying the heat conduction oil A to waste heat utilizing equipment through a pipeline to obtain utilized heat conduction oil B; then feeding back the heat conduction oil B to the heat exchanger through the pipeline for recycling. Compared with a traditional methodof directly conversing the coking waste heat into steam for utilizing, the distributed utilization method of the coking waste heat has the advantages of cleanness, low carbon and high energy efficiency utilization rate; in addition, the production of a large amount of wastewater in the waste heat utilization process is also avoided, so that the utilization cleanliness of coking waste heat energy is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of amateur heat utilization of coking chemical industry, in particular to a distributed utilization method and utilization system of coking waste heat. Background technique [0002] The coking industry is not only an important energy production sector, but also a high energy consumption and high pollution industry. In the processing process of the coking industry, as far as the heat from the coke oven product is concerned, a large amount of waste heat of raw gas, red coke and flue gas will be brought out. The recovery of these waste heat plays a very important role in saving energy, reducing consumption and improving economic benefits in coking plants. The existing technologies for the utilization of waste heat from raw gas, red coke and flue gas are generally based on the idea of ​​recycling these waste heat energy through inert gas circulation to recover sensible heat, and then converting it into high-temperat...
