Description
Technical field
The invention provides a kind of desulfation dust-extraction device that can be used for boiler stove flue gas desulfurization and dedusting, relate in particular to the reinforced concrete structure of desulfation dust-extraction device.
Background technology
At present, China's boiler stove desulfurating dust removing device for flue gas is the major and minor tube granite masonry construction and the steel welding structure of band Venturi tube basically.The granite structural volume greatly also must manufacture big buck sedimentation basin, and it is difficult to draw materials in the whole country; Steel design has a strong impact on operational reliability because weak acid corrosion in the running and erosive wear usually cause the equipment corrosion perforation again, can not guarantee the requirement of properties of product.
Summary of the invention
The object of the invention and task are to the deficiency that exists in the said goods technology, and a kind of composite device of moisture film desulfurization and dedusting is provided, and adopt reinforced concrete structure, and desulfurization and dedusting are integrated in one.Both reduced the larger volume and the floor space of traditional granite water dust scrubber, the cycle in service life for many years that can guarantee again can not influence operational reliability because of etching problem; And the automatic control system that installing is easy to adjust effectively improves desulfurization dust-removing efficiency.
Solution of the present invention is, device by a square box and above its rear portion the cylindrical shape cyclone dust collectors form.The flue gas of from combustion apparatus, discharging gets into square box by air inlet, and at first the absorption liquid with the atomizer ejection mixes, and flue gas humidification weightening finish back is impacted to the moisture film dividing plate.Moisture film dividing plate top is provided with the water distribution membrane structure of being made up of along plate water distributor and water distribution, forms adherent current, cleans dust in flue gas and sulfur dioxide, and flue gas is through under the moisture film during square channel, and the cascade that is formed once more cleans, absorbs.The stabilier at casing middle part and rear bulkhead guiding flue gas in dilatation, turn back move in impact liquid level and import the absorption liquid of lower box once more.The casing rear portion is provided with door type water fender of 3-5 layer inclination, further impels dust and sulfur dioxide reaction product particle coalescence in the flue gas, falls after rise to the bottom absorption liquid.Flue gas moves upward and is forced rotation through demist eddy flow plate; Make the water smoke in the flue gas fully separate, condense in cylindrical shape demister inwall; Relying on gravity to act on section is downward earial drainage on the leg-of-mutton dash ring groove of chamfer; Two drainpipes through eddy flow plate next door enter the bottom absorption liquid, and flue is the air outlet discharge from demister top.Dust in flue gas is absorbed liquid and captures, and sulphite that sulfur dioxide and the reaction of absorption liquid neutral and alkali medium generate and sulphate particle are discharged by the scraper plate ash exhauster in the groove in the sedimentation of lower box subsider.On subsider top, install and open, shut down the liquid level control structure, guarantee accurately and efficiently to move in the liquid level of opening, shut down two states.The water inlet of water distributor by noncorrosive pump from the lower box absorption liquid or establish circulatory pool in addition and extract, closed cycle.
The configurable ph value of the present invention is monitored and automatic medicine adding apparatus, can satisfy the occasion of different desulfuration efficiency requirements.
Description of drawings
Fig. 1 is the structural representation of desulfation dust-extraction device.
The specific embodiment
As shown in the figure, 1 is square box, and 2 is air inlet, and 3 is atomizer; 4 be water distribution along plate, 5 is water distributor, 6 is the moisture film dividing plate, 7 is stabilier; 8 is rear bulkhead, and 9 inclinations are a door type water fender, and 10 is drainpipe, and 11 is the cylindrical shape demister; The inwall on its top has been done chamfer triangle water-blocking groove, and 13 is air outlet, and 14 is fluid level control device, and 5 is the scraper plate ash exhauster.
Desulfation dust-extraction device has reinforced concrete structure, comprises a square box 1 and a cylindrical shape demister 2, and casing 1 front portion is provided with moisture film dividing plate 3, forms water distribution membrane structure 5 by water distribution along plate 4 and water distributor on it.The bottom is provided with stabilier 6 and rear bulkhead 7.Door type water fender 9 of 3-5 layer inclination is set; Eddy flow plate and drainpipe 10 are equipped with in the demister bottom; It is the leg-of-mutton three road water-blocking grooves 11 of chamfer that the top cylinder inboard wall has been done section, and the gas approach of casing is equipped with atomizer 12; One side of casing is equipped with scraper plate ash exhauster 13; Control of cabinet configuration liquid level and ph value monitoring device 14.
This device is than granite water dust scrubber more compact structure, takes up an area of forr a short time, integrates dedusting and desulfurizing function, has better operational reliability.
