Novel semi-coke gasifier device

Abstract

The invention belongs to the technical field of energy equipment and relates to a novel semi-coke gasifier device. The novel semi-coke gasifier device comprises an upper gasifier body and a lower gasifier body, a feeding device and a steam-water separator are communicated and arranged on the upper portion of the upper gasifier body, a temperature sensor and a coal level detector are arranged in the upper gasifier body, and slag breaking devices, a fire grate device, a slag storage chamber and a screw conveyor are sequentially arranged in the lower gasifier body from top to bottom. The slag breaking devices are uniformly mounted on a supporting mounting plate, a transmission device is arranged at one end of the supporting mounting plate, one end of the transmission device is connected withthe slag breaking devices while the other end is electrically connected with a motor, and an air supply pipeline is arranged in the slag storage chamber. By the slag breaking devices, the semi-coke utilization rate is increased; by the fire grate device, fire grate blockage caused by large slag blocks is effectively avoided, and accordingly the service life of a fire grate is prolonged while the gasifying rate is increased. By combination of the air supply pipeline and the temperature sensor, a proper ratio of vapor and air in the gasifier device, coal gasifying efficiency and gas colorific value are effectively guaranteed.

Description

technical field [0001] The invention relates to a novel blue charcoal gasifier device, which belongs to the technical field of energy equipment. Background technique [0002] The semi-coke gasification furnace device is a production equipment that converts semi-coke into flammable gas. Its working principle is to add semi-coke into the gasification furnace, and blow in the mixed gas of air and water vapor as a gasification agent. Physicochemical reactions occur, resulting in flammable gas (water gas). [0003] The production equipment and technology of traditional gasifiers are relatively extensive. The pagoda-shaped structure combined with the external slag discharge method is adopted. The air supply is uneven, which can easily cause partial burning and reduce the service life of the grate. conversion efficiency and semi-coke gasification rate. The traditional gasification process controls the ratio between coal and gasification agent by controlling the saturation tempera...

Problems solved by technology

[0003] The production equipment and technology of traditional gasifiers are relatively extensive. The pagoda-shaped structure combined with the external slag discharge method is adopted. The air supply is uneven, which can easily cause partial burning and reduce the service life of the grate. conversion efficiency and semi-coke gasification rate

The traditional gasification process controls the ratio between coal and gasification agent by controlling the saturation temperature after water vapor and air are mixed. Since air and water vapor cannot be completely mixed repeatedly, the proper ratio of air and water vapor cannot be guaranteed, which affects coal gasification. gasification efficiency and calorific value of gas
