Problems solved by technology
[0003] In the waste heat recovery process of raw gas, the tar vapor in the raw gas is cooled and precipitated. The lower the cooling temperature of the raw gas, the greater the amount of tar precipitated. The high temperature at the inlet of the rising pipe of the raw gas causes pyrolysis and thermal condensation to re-vaporize the tar. The vaporized residue is attached to the heat exchange interface. After a period of time, under high temperature conditions, the tar is carbonized at the entrance of the riser pipe, which is difficult to clean up; when the heat pipe heat exchange technology is used to recover the waste heat of raw coal gas, a certain amount The water is used as the heat transfer medium, and the liquid water absorbs the heat of the raw gas at the heat-absorbing end of the heat pipe and turns into steam, and the steam flows into the vacuum tube again after heat exchange, and the steam is continuously circulated and transported. The temperature is still higher than 300°, and the heat in the raw gas cannot be fully utilized

Description
technical field [0001] The invention relates to the field of coking furnace waste heat utilization, in particular to a coking furnace waste heat full utilization system for preventing tar from forming graphite. Background technique [0002] In the coking process, a large amount of flue gas containing waste gas is produced, and the waste gas refers to the dust gas. It cannot be directly supplied to users and must be treated with dust removal. Because the furnace dust in the raw gas may not only block the pipeline during the transportation process, but also because the alkaline substances in the furnace dust may fuse with the acidic refractory materials (slagging) at high temperature during combustion, thereby reducing the combustion chamber of the coke oven. The performance and service life of equipment such as regenerators and hot blast stoves. The level of dry dust removal is determined by the user's requirements and technical and economic feasibility. Generally, the dust...
