The pyrolysis of particulate coal requires the recovery of mixed gas from the roof of a semi-coke oven, also known in the industry as: raw gas. Purifying the mixed gas by a matched purifying device, and separating the collected mixed gas from coal tar, coal dust and ammonia water. The separated gas is sent out for use through a pipeline. The mixed coal tar containing ammonia water naturally flows through a pipeline and enters an ammonia water separating tank or pool to further separate light coal tar and heavy coal tar for sale. Ammonia water needs to enter a wastewater treatment plant for treatment. At present, two furnace types are adopted for producing semi-coke, coal tar and recovered coal gas by pyrolysis of domestic granular coal. The mode of recovering coal tar, coal gas and ammonia water is different from furnace type. One is a square carbonization chamber, which uses return gas. The furnace top introduces the gas into the gas collecting tank through a gas collecting bridge type pipeline, and sprays water to reduce dust and cool the gas on one side of the gas inlet tank, so as to perform primary dust removal and cooling treatment. The gas collecting tank is generally cuboid, mixed gas enters the gas collecting tank from the top, then enters the main mixed gas pipeline through a pipeline, the main mixed gas pipeline is connected at a high position, enters the Venturi tower, and enters the transverse pipe cooler at a low position, and then enters the electric tar precipitator at a low position, and the high position enters the gas fan for delivery. The bottom of the gas collecting tank is provided with a dust cleaning manhole flange, an ammonia water discharge pipeline and a valve. The advantages are that: coal can generate mixed gas such as coal gas, coal tar, coal dust, condensation water and the like in the pyrolysis process. When the mixed coal gas is collected, dust is reduced and cooled through a gas collecting tank, a venturi tower and a transverse tube cooler, and then the mixed coal gas enters an electric tar precipitator to collect the mixed coal tar in the mixed coal gas. And discharging the coal tar from the low point at the bottom of the electric tar precipitator into a mixed coal tar pipeline for coal tar separation. The coal gas purified by the electric tar precipitator is sent to a using unit through a coal gas fan. The specific gravity of the coal tar is low, the light coal tar can reach 0.92-0.97 mg/mL, the color is clear and light red, the specific gravity of the heavy coal tar is 1.02-1.048 mg/mL, and the oil product is better. Disadvantages: the device is provided with: the gas collecting tank, the venturi tower and the horizontal pipe cooler are cooled, so that a large amount of cooling water is needed for the process equipment, and water pollution and waste can be caused. In addition, a large amount of wastewater is generated, a large ammonia water pool is needed to be built for ammonia water treatment, the difficulty in treating the ammonia water is high, and the investment cost is high. The other is a round carbonization chamber, and the return gas is not used. The furnace top directly introduces the gas into the main mixed gas collecting pipeline of each furnace through the mixed gas collecting bridge type pipeline, the main mixed gas collecting pipeline of each furnace respectively enters the main mixed gas collecting pipeline in front of the electric tar precipitator, and then the main mixed gas collecting pipeline respectively enters a plurality of electric tar precipitator at low positions through the branch pipelines for gas purification. The advantages are that: coal can generate mixed gas such as coal gas, coal tar, coal dust, condensation water and the like in the pyrolysis process. And the mixed gas is collected and purified, the gas is recovered, the matched equipment is needed for separating the coal tar, the process is simple, the equipment investment is low, and the investment cost is low. The water consumption is low, the produced ammonia water is low, and a large ammonia water storage tank or pool is not required to be built. Disadvantages: the specific gravity of the coal tar is relatively high, the specific gravity of the light coal tar is 0.97-0.99 mg/mL, and the color is brownish red. The specific gravity of the heavy coal tar is 1.040-1.070 mg/mL, and the color of the coal tar is darker.
How to purify and separate coal gas, coal dust, coal tar and condensed water (trace condensed water can be generated in the pyrolysis process of coal) in the recycled mixed coal gas is a key technical problem of the carbonization device. In the pyrolysis process of the granular coal, coal gas, coal tar and condensed water are decomposed, dust is generated in the blanking combustion process, mixed coal gas is formed in a hearth, and the mixed coal gas is completely formed to enter a collecting pipeline under the action of negative pressure of a coal gas fan. Analysis considered that: the quality of the coal tar is affected, and the main problem is that the impurities in the coal tar are too much; and then, separating coal tar in the mixed gas, wherein the coal tar is not in a proper temperature range. The main problems to be solved are dust removal, cooling, and water consumption and pollution and waste of water resources are greatly reduced. In order to solve the problem, a novel dust removal cooling device for collecting mixed gas of the granular coal pyrolysis semi-coke furnace needs to be designed.
