Description
1, technical field
The utility model belongs to the chemistry or the biological cleaning field of waste gas, is specifically related to a kind of electron beam ammonia process of desulfurization denitrification apparatus.
2, background technology
At present, at existing electron beam ammonia type flue gas desulfurizing denitrification apparatus and relevant patented technology (ZL95120837.7, ZL95115279.3) in, the flue gas that contains sulfur dioxide and nitrogen oxide is in the irradiation reaction device, by adding desulfurizing agent ammonia, under the irradiation of electron beam, the flue gas that contains ammonium sulfate and ammonium nitrate particulate that reaction generates directly enters the accessory substance gatherer through flue, carries out dust removal operation again.Can collect accessory substance by the accessory substance gatherer though do like this, the purpose of sulfur dioxide in flue gas and nitrogen oxide is removed in realization, but because by-products content height in the flue gas, be that dust concentration is big, the accessory substance sedimentation is incomplete, the accessory substance of considerable part enters the discharging flue, does not reach the discharge standard of the existing exhaust gas dust content of national regulation.Make accessory substance collector design scale big simultaneously, the design objective height just can have higher dust removal efficiency.
3, summary of the invention
The purpose of this utility model provides a kind of electron beam ammonia type flue gas desulfurizing denitrification apparatus, this device not only can make the accessory substance that produces in the desulphurization denitration process obtain sedimentation more completely, the flue gas pernicious gas content of emptying reduces, and can alleviate the live load of accessory substance gatherer effectively, reduce the design scale of accessory substance gatherer, effectively improve the collection efficiency of accessory substance gatherer, and can satisfy the shielding requirements that a piece of wood serving as a brake to halt a carriage that electron beam irradiation produces causes the X-radiation protection, make the device operation safer.
The utility model electron beam ammonia process of desulfurization denitrification apparatus contains flue gas conditioning tower, electron accelerator, irradiation reaction device, flow tank, accessory substance gatherer and air-introduced machine, and connects successively; Be characterized between irradiation reaction device that installs and accessory substance gatherer, a flow tank being set, bottom in the flow tank is provided with vertical drag conveyor and horizontal drag conveyor, on two sidewalls of flow tank, have the interface of connection irradiation reaction device and the interface I and the interface II of auxiliary connection product collector, on the sedimentation tank wall, also be provided with acoustic wave soot blower.It is 3～5 seconds in the time of staying of flow tank that flue gas is set.
When the flue gas that contains sulfur dioxide and nitrogen oxide with after the desulfurizing agent gas ammonia mixes, under certain temperature and humidity, under the effect of irradiation of electron beam, sulfur in smoke and nitrogen oxide and ammonia react generate the particulate of ammonium sulfate and ammonium nitrate, after flue gas enters flow tank, because the variation of air velocity, the prolongation of the time of staying, make chemical reaction carry out more thoroughly, the particle collision chance is more, and particle collision also can be bigger in conjunction with the chance of growing up, and the quantity of particles settling also can increase, utilize gravitational settling in flow tank, thereby can reduce the live load of accessory substance gatherer.Stick to accessory substance on the sedimentation tank wall with airflow collision,, rely on the bottom of gravitational settling at flow tank by the acoustic vibration that the acoustic wave soot blower that is arranged on each position of flow tank sends.The accessory substance that falls to the bottom is collected by the drag conveyor that is provided with, and by another drag conveyor accessory substance is sent flow tank again.
The size of flow tank is according to building the place, the size of accessory substance gatherer, and a piece of wood serving as a brake to halt a carriage causes 2～20 seconds time of staying that factor such as X ray shielding protection is designed to flue gas, can be the accessory substance gatherer and alleviates live load 5%～35%.
The beneficial effects of the utility model are, can be when satisfying the radiation shield requirement of shelter, prolong the time of staying of ash-laden gas, increase the settling amount of accessory substance in flow tank, thereby alleviate the live load of accessory substance gatherer effectively, reduce the design scale of accessory substance gatherer, improve the utilization ratio of accessory substance gatherer effectively, thereby provide condition for reaching higher standard limit of smog release.Flow tank simple in structure, the expense of annexes such as drag conveyor of setting up and acoustic wave soot blower is much smaller than the design scale of the accessory substance gatherer of considering by the technological design of not establishing flow tank and the expense of investment thereof.
