Pneumatic discharging mechanism

Abstract

The invention discloses a pneumatic discharging mechanism. The pneumatic discharging mechanism comprises a receiving channel, a diagonal bottom plate is arranged on an opening in the lower end of the receiving channel, the upper end of the bottom plate is located in the receiving channel and is closely connected with a side wall of the receiving channel, and a discharge opening is formed by the lower end of the bottom plate and the lower end of the side wall of the corresponding receiving channel; a baffle is arranged below a bottom plate, and a gap forming channel is formed between the baffle and the bottom plate; a horizontally or slightly inclined storage plate is arranged at the lower end of the baffle, and the storage plate is located below the discharge hole; an opening in the lower end of the gas channel is communicated to the upper surface of the storage plate, an opening in the upper end of the gas channel is communicated with either an air outlet of a compressed gas device or a pneumatic component. According to the pneumatic discharging mechanism provided by the invention, the power consumption is low in a pneumatic discharging process; furthermore, the pneumatic discharging mechanism is simple in structure, easy to process, long in life, wide in application scope, even to discharge, simple to control, small in size and low in space requirement, and is free from fault and maintenance.

Description

technical field [0001] The invention belongs to the field of material collection and discharge equipment, and in particular relates to a pneumatic unloading device for solid particle materials. Background technique [0002] my country controls SO 2 and NO x The emission task is very heavy, and the emission standards are getting higher and higher. At present, most of the waste gas purification adopts wet technology, which consumes a lot of water resources and causes secondary pollution, and cannot desulfurize and denitrify at the same time, especially in the coal-rich northern my country. In areas short of water, water resources restrict economic construction and development. [0003] Activated carbon flue gas purification technology is a recyclable dry flue gas purification technology. At a temperature of 80-150 ° C, through the adsorption and catalysis of activated carbon, the sulfur dioxide, oxygen and water in the exhaust gas are converted into sulfuric acid adsorbed on ...

AI Technical Summary

Problems solved by technology

At present, in the aspect of activated carbon feeding in the desulfurization tower, a rotary star unloader, long-axis unloader or roller feeder is usually used to discharge the activated carbon from the desulfurization tower through various movable devices or move the activated carbon into another One equipment, but activated carbon is similar to other solid particle materials, it will be crushed and pulverized under certain contact or touch, and the crushed and pulverized activated carbon cannot be reused, resulting in a large waste of activated carbon

The cost of activated carbon adsorption catalyst is high, and the high breakage rate caused by improper operation will increase the production cost of the enterprise and affect the smooth operation of the equipment

In addition, the existing equipment of this type consumes a lot of power, requires high processing precision, and is difficult to produce. Moreover, the failure rate of the equipment in the activated carbon atmosphere is high, and repair and maintenance are difficult, which brings a large production cost and affects the performance of the adsorption desulfurization tower.
