Abstract
The utility model provides a new device for boilers and stoves flue gas desulphurization and dedusting adopting a reinforced concrete structure. A water distribution membrane structure, a diaphragm for guiding smoke two-stage impacting and a multilayer kink plate dehydration structure are arranged in a square box; the upper side of the empennage is a cylinder cyclone demister, and a rotating-stream tray and two drainage pipes are arranged at the lower part; an annular groove and an air outlet are arranged at the upper side of the cylinder body; a scraper dust discharge mechanism is arranged at one side of the box. The utility model achieves an integration of flue gas desulphurization and dedusting and an auto controlling for liquid level, dust discharging and pH value. Compared with the granite water film separator, the utility model has the advantages of more compact structure and less land occupation, which combines desulphurization and dedusting together and has a better operation reliability.
Description
The utility model provides a kind of composite device that can be used for boiler stove flue gas desulfurization and dedusting.Adopt reinforced concrete structure.
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 substantially.The granite structural volume is big, 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.
The purpose of this utility model and task are the deficiencies 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 utility model is, device by a square casing (1) and above its rear portion cylindrical shape cyclone demister (12) form.The flue gas of discharging from combustion apparatus enters square box by air inlet (2), and at first the absorption liquid with atomizer (3) ejection mixes, and flue gas humidification weightening finish back is impacted to moisture film dividing plate (6).Moisture film dividing plate top is provided with the water distribution membrane structure of being made up of along plate (4) water distributor (5) and water distribution, forms adherent current, cleans dust in flue gas and sulfur dioxide.Flue gas is by under the moisture film during square channel, and the cascade that is formed once more cleans, absorbs.The stabilier (7) at casing middle part and rear bulkhead (8) guiding flue gas impact liquid level and import the absorption liquid of lower box once more in dilatation, turnover are moved.The casing rear portion is provided with 3～5 layers of inclination and falls L shaped water fender (9), 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 to rotation by demist eddy flow plate (11), make the water smoke in the flue gas fully separate, condense in cylindrical shape demister (12) inwall, relying on gravity to act on section is downward earial drainage on the leg-of-mutton dash circular groove structure of chamfer, two drainpipes (10) through eddy flow plate next door enter the bottom absorption liquid, purify flue gas and discharge from demister top air outlet (13).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 (15) in the groove in the sedimentation of lower box subsider.On subsider top, install and open, shut down level controling mechanism (14), 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 utility model is monitored and automatic medicine adding apparatus, can satisfy the occasion of different desulfuration efficiency requirements.
As shown in the figure, (1) is the square casing, and (2) are air inlet, (3) be atomizer, (4) be water distribution along plate, (5) are water distributor, (6) be the moisture film dividing plate, (7) are stabilier, and (8) are rear bulkhead, (9) for tilting L shaped water fender, (10) are drainpipe, and (11) are demist eddy flow plate, (12) be the cylindrical shape demister, the inwall on its top has been done chamfer triangle water-blocking groove, and (13) are air outlet, (14) be fluid level control device, (15) are the scraper plate ash exhauster.
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.
