Abstract
The utility model discloses a desulfurization device, wherein, a prewashing tower is connected in series in an air inlet pipeline for communicating with a desulfurization tower and a flue gas output pipeline in the desulfurization device, so that flue gases are dedusted and cooled by the prewashing tower before entering the desulfurization tower. In terms of the utility model contributing to improved desulfurization and denitrification efficiency of the entire system and higher purity of materials separated out by crystallization, both the content of flue dust in the flue gases and the flue gas temperature are markedly reduced as a result of flue gas prewashing. Moreover, the utility model leads to a reduction in risks of desulfurization tower blockage, equipment abrasion and desulfurization tower ageing under high temperature conditions, thereby prolonging the service life of the desulfurization device.
Description
Technical field
The utility model relates to industrially desulfurized equipment technical field, particularly a kind of flue gas desulfur device of thermal power generation station-service.
Background technology
In the sulfur removal technology in present thermal power plant, adopt the limestone-gypsum method or the ammonia process of desulfurization usually, no matter use which kind of method, all include a desulfurizing tower device in its device.Existing desulfurizing tower device is normally in service, because it is higher to enter the dust content of desulfurizing tower, after the long-time running, flue dust is piled up in desulfurizing tower gradually, cause the aging of desulfurizing tower obstruction and corollary equipment wearing and tearing and desulfurizing tower easily, the operational reliability of desulfurizer reduces, the shortening in service life.In ammonia desulfurizing process, because flue-gas temperature is too high, after high-temperature flue gas entered desulfurizing tower, desulfurizing agent ammoniacal liquor was met vaporization at high temperature, also can cause the escaping of ammonia especially, was unfavorable for that the desulfurization of ammoniacal liquor absorbs, and desulfurized effect is poor, and is bigger to the pollution of environment.
The utility model content
The purpose of this utility model provides and a kind ofly can reduce the smoke content in the flue gas and the desulfurizer of flue-gas temperature.
The technical solution of the utility model is: a kind of desulfurizer, comprise desulfurizing tower, on desulfurizing tower, be provided with the outlet of flue gas inlet and outlet piping and desulfurizing agent inflow entrance and desulphurization reaction pulp flow, also comprise a flue gas prewashing column, this flue gas prewashing column is serially connected in the admission line of desulfurizing tower, this flue gas prewashing column is provided with flue gas air inlet/outlet and pre-wash liquid inflow entrance and pre-wash reaction slurry flow export, the smoke air inlet of this flue gas prewashing column is communicated with the flue gas output channel, and its flue gas gas outlet is communicated with the desulfurizing tower air inlet.
Pre-wash liquid inflow entrance on the described flue gas prewashing column is communicated with the outlet of the desulphurization reaction pulp flow of desulfurizing tower, and its pre-wash reaction slurry flow export is connected with the thiamine fertilizer process units.
Described thiamine fertilizer process units is independent the setting, it comprise reaction slurry crystallizing evaporator, cyclone,
Described thiamine fertilizer process units is independent the setting, and it comprises reaction slurry crystallizing evaporator, cyclone, centrifuge, drying machine and finished product packing machine.
The pre-wash liquid circulating device that on described flue gas prewashing column, also is provided with pre-wash liquid spray equipment and is communicated with it.
In described flue gas prewashing column, also be provided with the reaction slurry agitating device.
Adopt said structure, utilize the ammoniacal liquor raffinate of desulfurizing tower that flue gas is carried out pre-wash by prewashing column, can obviously reduce smoke content and flue-gas temperature in the flue gas, thereby improve the desulfurization removing nitric efficient of whole system and the purity of crystallization precipitate material, and reduced the aging of desulfurizing tower under the obstruction of desulfurizing tower and equipment attrition and the high temperature, thereby prolonged the physical life of desulfurizer.
