Continuous discharging device with controllable discharging speed, desorption tower and adsorption tower

Abstract

The invention provides a continuous discharging device with controllable discharging speed, and a desorption tower and an adsorption tower using the continuous discharging device with the controllabledischarging speed. The continuous discharging device with the controllable discharging speed comprises an adjusting part. The adjusting part can move up and down relative to a discharging opening. When the adjusting part moves relative to the discharging opening, the size of a gap between the adjusting part and the discharging opening can be changed, therefore the size of the discharging gap is adjusted, and thus the discharging speed is adjusted. Two discharging control manners can be provided, firstly, the distance between the discharging opening and a blocking plate is adjusted, when the discharging speed meets the requirement, rotating of a cam is stopped, and at the moment, activated carbon is discharged continuously; and secondly, the discharging speed is controlled by means of rotating frequency of the cam, namely, the rotating speed of the cam is fixed, and then control over the discharging speed can be achieved by controlling the rotating frequency of the cam. The device canachieve continuous discharging of materials, and the discharging speed is controllable.

Description

technical field [0001] The invention relates to the technical field of material feeding devices, and more specifically relates to a continuous feeding device with controllable feeding speed, a desorption tower and an adsorption tower. Background technique [0002] In the field of flue gas treatment, the use of activated carbon for desulfurization and denitrification is the mainstream flue gas treatment technology. [0003] At present, the activated carbon desulfurization and denitrification integrated flue gas treatment technology is widely used in the iron and steel industry. The activated carbon desulfurization and denitrification integrated flue gas treatment technology will use the analysis tower and the adsorption tower, and the analysis tower and the adsorption tower are the core equipment of the technology. In the process of flue gas treatment, the amount of activated carbon feeding is the core control parameter. [0004] Most of the existing feeding devices used in ...

AI Technical Summary

Problems solved by technology

The rake device is used to realize the activated carbon feeding, and the activated carbon feeding is intermittent, which is easy to cause problems such as activated carbon accumulation, agglomeration, and hot spots.

Moreover, during the movement of the rake device, it will also wear the activated carbon, which reduces the desulfurization and denitrification effect of the activated carbon.
