Cyclone high-temperature raw coke oven gas dust collector and working method thereof

Abstract

The invention relates to a cyclone high-temperature raw coke oven gas dust collector and a working method thereof. The cyclone high-temperature raw coke oven gas dust collector comprises a cyclone dust collector, wherein the cyclone dust collector consists of an inner bucket and an outer bucket; an air inlet tube is arranged on one side of the upper part of the outer bucket; an air outlet tube is arranged on the other side of the upper part of the inner bucket; the inner bucket is provided with an inner bucket inner scraper plate mechanism and an inner bucket outer scraper mechanism; the outer bucket is provided with an outer bucket inner scraper plate mechanism; a slag cleaning mechanism is arranged at the bottom of the outer bucket; the inner bucket inner scraper mechanism, the inner bucket outer scraper plate mechanism and the outer bucket inner scraper mechanism all consist of corresponding screw rods and scraper plates; the scraper plates can be moved upwards and downwards along the inner wall of the inner bucket, the outer wall of the inner bucket and the inner wall of the outer bucket to scrape off tar under the driving of the screw rods respectively; a slag scraper plate and a slag groove funnel are arranged in the slag cleaning mechanism; the slag cleaning scraper plate is capable of moving and scraping off tar impurities along the bottom of the outer bucket; the slag groove funnel is used for discharging the tar impurities. The cyclone high-temperature raw coke oven gas dust collector is capable of ensuring that a cyclone dust collector is operated normally in the high-temperature raw coke oven gas dust collection process, and further is reasonable in structure, convenient to use, reliable to work and ideal in effect.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery of high-temperature raw gas, in particular to a cyclone-type high-temperature raw gas dust collector for centralized waste heat recovery of high-temperature raw gas in a coke oven riser and a working method thereof. Background technique [0002] The waste heat recovery and utilization technology of high-temperature raw gas in the coking industry has been developed for decades, but the results are not satisfactory. The centralized recovery of waste heat from high-temperature raw gas proposed in recent years is recognized as a good research direction. However, when this method is used, the dust reduction of high-temperature raw gas becomes a problem, because in addition to common impurities, high-temperature raw gas also has the following characteristics: 1) high temperature; 2) gas is flammable; 3) contains tar. [0003] Existing dedusting technology is not suitable for high-temperatur...

Problems solved by technology

Using electrostatic dust removal, prone to explosion

The use of a cyclone dust collector needs to solve the problem of tar hanging. Usually, if the cyclone dust collector is used for dozens of days, it will be blocked because the interior is full of tar
