Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a synthetic ammonia semi-water gas desulfurization tower. Background Art

[0002] Semi-water gas is a type of fuel gas that uses coal and water as gasification materials to gasify. Semi-water gas is produced by blowing steam and air into a gasifier to react with red-hot anthracite or coke. It is a mixture of water gas and generator gas. It is mainly used in the coal chemical industry and is sometimes used as fuel. Its main components are a mixture of carbon monoxide, hydrogen, other inert gases and combustible methane, tar, phenol and other substances. It can generally be used as a coal chemical raw material, especially the raw gas for small-scale synthetic ammonia units. It is sometimes also used as fuel gas. Semi-water gas can be used to obtain the raw gas for synthetic ammonia after desulfurization, so workers often use desulfurization towers to desulfurize semi-water gas.

The left side of the storage box is fixedly connected to the right side of the tower body. The output end of the rotating motor power passes through the tower body and is fixedly installed with a turntable. The back of the turntable is fixedly installed with a connecting shaft. Two limit seats are fixedly installed on the inner wall of the tower body. The interiors of the two limit seats are slidably connected with a moving frame. The inner wall of the moving frame is in contact with the outer surface of the connecting shaft. Two moving plates are fixedly installed on the outer surface of the moving frame. The left side of the tower body is fixedly installed. There is an air pump, the output end of the air pump power passes through the tower body and is fixedly connected to a five-way pipe, the outer surface of the five-way pipe is fixedly connected to the inner walls of the two movable plates; this patent achieves the purpose of increasing the contact area between the desulfurizer and the semi-water gas by providing a rotating motor, a turntable, a connecting shaft, a limit seat, a movable frame and a movable plate. However, the device only improves the effect of full contact between the semi-water gas and the desulfurizer inside the tower body by moving the five-way pipe left and right, and the nozzle has a poor atomization effect on the desulfurizer. Therefore, the effect of full contact between the semi-water gas and the desulfurizer inside the tower body is general, which affects the quality of the desulfurization processing.
