Background
At present, a transverse pipe type cooler is mainly adopted in the cooling process of gas in the metallurgical coking and chemical industry, and has the advantages of convenience in operation, stability in operation, high working efficiency and the like. All set up sprinkler on each section upper portion of horizontal pipe cooler shell side, spray the aqueous ammonia that contains the coal tar in succession to the deposited tar sediment, dust and free carbon of purge tube outer wall. However, after long-term accumulation, impurities attached to the tube wall of the horizontal tube cooler cannot be completely washed, so that resistance is increased, and the heat transfer coefficient is reduced. The horizontal pipe cooler is an important link of a coal gas purification process, and the normal operation of a coal gas system is directly influenced by the resistance of the horizontal pipe cooler. The serious blockage of the transverse pipe cooler is a common problem of various coking plants, and although countless methods are adopted when the problem is solved, the effect is little.
The traditional method is resistance reduction: steam purging, light tar and hot ammonia water cleaning effect are not good. Coal gas enters from the top of the cross cooler, the upper section and the lower section are cooled by circulating water, the coal gas and cooling water carry out countercurrent heat exchange, the temperature is quenched to enable naphthalene and tar residues in the coal gas to be condensed, and parts of the naphthalene and tar residues are attached to the pipe wall.
