Technical Field
[0001] The utility model belongs to the technical field of spiral air intake water cooling devices for coal gas, in particular to a spiral air intake water cooling device for recovering and purifying coal gas from a submerged arc furnace. Background Art
[0002] The spiral air intake and water cooling device for recovering and purifying coal gas from submerged arc furnaces is a device designed to recover and purify coal gas in a high-temperature environment. This device uses spiral air intake technology and a water cooling system to effectively reduce the temperature of coal gas from submerged arc furnaces, thereby ensuring the normal operation of the system and extending the service life of the equipment.
[0003] At present, most equipment for recovering and cooling coal gas from ore-heating furnaces usually sets up cooling and dust removal separately, requiring the two devices to work at the same time. This not only increases the floor space occupied by the equipment, greatly wastes the usable area of the site, but also increases the maintenance cost. In addition, there are certain limitations on the use site, which greatly increases the company's investment in equipment. For this reason, a spiral air intake water cooling device for recovering and purifying coal gas from ore-heating furnaces is proposed. Utility Model Content
[0004] The purpose of the present invention is to provide a spiral air intake water cooling device for recovering and purifying coal gas from an ore-heating furnace. By setting a water cooling component, specifically, the staff starts the motor to drive the hollow shaft and the auger to rotate together and transport the coal gas. Since the hollow shaft and the auger are both hollow and communicated, the coal gas inside the cabin will be cooled. The water cooling system and the transportation are set together, which solves the problem that most of the current equipment usually separates cooling and dust removal when recovering and cooling the coal gas from an ore-heating furnace, requiring the two devices to work at the same time. In this way, not only the floor area of the equipment is increased, which greatly wastes the use area of the site, and the maintenance cost is also increased.
