Closed calcium carbide furnace tail gas purification device

Abstract

The invention discloses a closed calcium carbide furnace tail gas purification device which comprises a device box, an external pipeline, windmill blades, a groove, a sliding rail and a door plank.Thedevice box is internally provided with a first filter screen, the side wall of one end of the device box is provided with the external pipeline, and the external pipeline is located above the first filter screen; a second filter screen is mounted in the device box and located above the external pipeline, a mounting box is mounted at the top end of the second filter screen, a motor is arranged inthe mounting box, a rotating shaft is mounted at the output end of the motor through a coupler, and windmill blades are arranged on the outer wall of the rotating shaft; and fixing seats are mounted on the side walls of the ends, away from the external pipeline, of the device boxes. According to the closed calcium carbide furnace tail gas purification device, through the design of the first filterscreen, water can be filtered, a mixer of the water and tail gas stays at the top end of the first filter screen, and the water can be conveniently recycled through a water pump.

Description

technical field [0001] The invention relates to the technical field of calcium carbide furnaces, in particular to a device for purifying tail gas of a closed calcium carbide furnace. Background technique [0002] With the development of society, calcium carbide furnace is the main equipment for the production of calcium carbide. In the calcium carbide furnace, due to the high temperature emitted by the arc, the furnace material is melted and reacted to form calcium carbide. Because the reaction temperature is as high as 2000 ° C, such a high temperature is difficult for general refractory materials. Therefore, the volume of the furnace body must be larger than the reaction space, that is to say, there should be a layer of charge between the reaction zone and the furnace lining to protect the furnace lining. When the calcium carbide furnace is in use, a purification device needs to be connected to clean the calcium carbide furnace. Purify the exhaust gas of the exhaust gas. T...
