Problems solved by technology

[0002] In the existing device system for the mixed reaction of powder and flue gas, when the storage tank for storing powder falls and transports the powder, the powder is easy to accumulate at the bottom of the tank, especially the powder that is easy to absorb moisture. The material is easy to form hard lumps after being damp, which makes the accumulation situation particularly serious
The solution to this problem in the traditional solution is usually to blow compressed air or mechanical agitation to dredge. This kind of solution has the following disadvantages: 1) The way of blowing compressed air has a certain effect in a short time, but because the compressed air will inevitably be mixed Long-term continuous air supply and blowing will easily make the moisture accumulate in the tank and then mix with the powder in the tank and gradually absorb it, thus aggravating the agglomeration of the powder in the tank; 2) Although the effect of mechanical stirring is better, However, the device structure design is complex, the volume is large, and the long-term operation energy consumption is high. The initial investment cost and long-term operation cost of the mechanical stirring method are relatively high.
This structure has the following disadvantages: 1) When using a mechanical airlock with a better airtight effect, the processing and matching precision of the airlock is required to be high, and the airlock is likely to be stuck or accelerated wear when the powder forms a hard block ;2) When using a mechanical air lock with average or poor processing quality and matching accuracy, the airtight effect is poor and air leakage is prone to occur

Abstract

The invention relates to the technical field of flue gas purification and particularly relates to a device system applicable to a flue gas and powder material mixed reaction. The device system applicable to the flue gas and powder material mixed reaction comprises a reactor, wherein a powder material inlet is formed in the top of the reactor, a powder material outlet is formed in the bottom of the reactor, a jacket sleeves the external wall of the reactor, a gas flow chamber which is used for circulating flue gases is arranged between the internal wall of the jacket and the external wall of the reactor, the internal cavity of the reactor communicates with the gas flow chamber through a bottom opening, a flue gas inlet is formed in the upper part of the sidewall of the reactor, and a flue gas outlet is formed in the upper part of the sidewall of the jacket; and a bottom opening of the jacket is downwards connected with a blanking pipeline, an adsorption chamber with a Venturi tube is arranged below the blanking pipeline, a gas inlet of the Venturi tube is connected with an external gas supply pipeline, and a gas outlet of the Venturi tube communicates with a material conveying pipeline. By adopting the technical scheme, the device system has the advantages that the problem that a mechanical air lock is short in life, is prone to blockage and is prone to rust corrosion after the mechanical air lock is corroded by water vapor is avoided, and the storing quality and conveying effect are ensured by the bridge breaking effect of a storage tank.
