Description
Technical field
The invention belongs to material collection discharging equipment field, be specifically related to a kind of Pneumatic blanking device of solid particle material.
Background technology
China control SO
2and NO
xdischarge task is very heavy, the standard of exhaust emission is also more and more higher, current exhaust purification adopts Wet technique mostly, also secondary pollution is caused while consumption great lot of water resources, and can not simultaneous SO_2 and NO removal, the particularly area of lack of water at northern China rich coal, water resource governs economic construction and development.
Active carbon flue gases purification is a kind of dry FGD process technology of resourcebility, at the temperature of 80 ~ 150 DEG C, by the adsoption catalysis of active carbon, the reaction of the sulphur dioxide in waste gas, oxygen G&W is converted into sulfuric acid and is adsorbed in the micropore of active carbon, realizes desulfurizing and purifying; At such a temperature, when adding ammonia, the NO in flue gas
xselective catalytic reduction reaction can be carried out on the activated carbon, generate nitrogen G&W, but in the process of desulphurization denitration at the same time, SO in waste gas
2concentration is higher has negative effect to denitration efficiency.
Absorption type desulfurizer is the nucleus equipment of active carbon dry desulfurizing process, and what technical application was more is fixed bed desulfurizer and moving bed desulfurizing tower.At present in the active carbon blanking of desulfurizer, the rotary Star-like unloader of usual employing, major axis discharger or roll feeder, by various head active carbon discharged from desulfurizer or active carbon moved in another equipment, but active carbon is similar to other solid particle materials, breaking and Dusting can be produced in certain contact or under touching, and active carbon after breaking and Dusting cannot reuse, causes a large amount of wastes of active carbon.The cost of charcoal absorption catalyst is higher, and running the high percentage of damage do not produced at that time can increase enterprise's productive costs and affect the smooth running of equipment.Such electricity consumption of equipment amount existing is large in addition, and requirement on machining accuracy is high, and production difficulty is large, and equipment failure rate is high in active carbon atmosphere, unscheduled maintenance difficulty, brings larger productive costs and have impact on the application competitive power of absorption type desulfurizer.
Summary of the invention
The object of the invention is to overcome the problems referred to above, there is provided a kind of specially for the pneumatic cutting agency of solid particle material, this device do not have power consumption, mechanical rotating part, structure simple, be easy to processing, failure rate is low, farthest reduce the crushing of solid particle material, reduce production and use cost.
Object of the present invention can be reached by following measures:
A kind of pneumatic cutting agency, it comprises rewinding passage, oblique base plate is provided with at the lower ending opening place of described rewinding passage, or a part for rewinding beneath galleries sidewall is oblique to the direction of corresponding sidewall arranges formation base plate, the upper end of this base plate be positioned at rewinding passage and with rewinding channel side wall compact siro spinning technology, the lower end of this base plate and the lower end of corresponding rewinding channel side wall form a discharging opening jointly; Be provided with plate washer in the below of described base plate, leave gap between described plate washer and base plate, the gas passage formed from upper end to the below of plate washer is closed in the both sides in this gap by rewinding channel side wall; The material stock plate being provided with level in the lower end of described plate washer or slightly tilting, this material stock plate is positioned at the below of described discharging opening; The lower ending opening of described gas passage passes to the upper surface of material stock plate, and the upper end open of described gas passage is connected with Ignitable gas devices air extractor duct or pneumatic members.
The present invention also comprises the pneumatic cutting agency that another kind has analog structure, it comprises rewinding passage, oblique base plate is provided with at the lower ending opening place of described rewinding passage, or a part for rewinding beneath galleries sidewall is oblique to the direction of corresponding sidewall arranges formation base plate, the upper end of this base plate be positioned at rewinding passage and with rewinding channel side wall compact siro spinning technology, the lower end of this base plate and the lower end of corresponding rewinding channel side wall form a discharging opening jointly; The sidewall of the below of described base plate or rewinding passage is provided with a compressed gas chamber, this compressed gas chamber has pressure gas entrance, compressed gas chamber is provided with the length long slit consistent with base plate lower end length in the position being close to base plate lower end, or the air outlet parts of compressed gas chamber extends and forms length and the consistent long slit of base plate lower end length together at base plate lower end and base plate below base plate, this long slit is the pressure gas outlet of described compressed gas chamber; Be provided with the material stock plate slightly tilted in described pressure gas exit, this material stock plate is positioned at the below of described discharging opening; Described pressure gas outlet passes to the upper surface of material stock plate.
