Abstract

The utility model relates to a spray fume purifier, which is composed of a case, a pressure boost chamber, a spray pipe and a wind force buffer sheet. The spray fume purifier is installed between a fume pipe and a chimney of a boiler, and is matched with a dust deposition pool, a circulation water pool and a water pump to be used to form a water circulation system Alkaline water forms a water spray zone provided with a certain end face and length in the purifier through the spray pipe. After enter the purifier, fume fully contacts with the water spray under the action of the wind force buffer sheet; the purposes of dust removal, desulphurization and smoke abatement are realized. The utility model has the advantages of high dust removal efficiency, simple structure and low production cost, and is the ideal equipment matched with large and medium boilers, fuel electric plants and cement plants to be used.

Description

Atomizing fume purifier

The utility model belongs to the flue gas purifying equipment supporting with Industrial Boiler, is specially adapted to the smoke dispersal, dust removal and desulphurization of medium-and-large-sized horizontal coal-fired boiler more than two tons.

At present, the deduster that coal-burning boiler uses mostly adopts dryness deduster and moist deduster two classes, and the dryness deduster is divided into two kinds of wind-force deduster and Electrostatic Absorption dedusters again.The dryness deduster reclaims the particulate in the flue gas plays a role, but desulfurized effect is poor, inconvenient operation.Though the efficiency of dust collection of moist deduster has raising, but the moisture film in clarifier inside does not form the water smoke section of certain-length, there is not the wind-force fender system yet, flue gas in clarifier and shipwreck are fully to contact, still do not reach desirable dust-removal and desulfurizing effect, and complex structure, the cost height, floor space is big, is difficult for promoting the use of.So people wait in expectation this deduster is further improved.

The purpose of this utility model is to provide a kind of integrate dedusting, desulfurization, smoke elimination, energy-conservation, and simple in structure, cost is low, and is corrosion-resistant, the boiler fume purifier device that efficiency of dust collection is high.

The purpose of this utility model is achieved in that atomizing gas cleaning apparatus, be arranged between the air-introduced machine and chimney behind the boiler smoke pipeline, with dust stratification pond 12, circulating water pool 13, water pump 14 supporting uses, it is characterized in that this device has a housing 1, supercharging storehouse 7 is housed in the housing 1, injection spray pipe 2 and wind-force buffer substrate tablet 15, the one end edge of injection spray pipe 2 is positioned on the 7 right walls of supercharging storehouse, the other end is connected with fixed head 8, fixed head 8 is fixed on housing 1 inwall, make injection spray pipe 9 be arranged on centre in the purifier shell 1 securely, constitute the atomizing flue gas cleaner with wind-force buffer substrate tablet 15; Housing 1 is cylindrical, and two ends are provided with ring flange respectively and advance mouth 4 and outlet flue 5, in the lower right side of housing 1 drainpipe 6 are set, and the lower-left side is provided with water inlet pipe 10; Supercharging storehouse 7 is a hydrostatic column, is arranged on the left side in the clarifier, and its lower end is connected with water inlet pipe 10, and the right wall in supercharging storehouse 7 and injection spray pipe 2 are connected; Have spray holes 9 on the injection spray pipe 2, the water smoke of injection spray pipe 2 ejections is formed with the water smoke section of certain end face and length in housing 1; Wind-force buffer substrate tablet 15 comprises air inlet buffer substrate tablet 11 and inner walls buffer substrate tablet 3, air inlet buffer substrate tablet 11 is circular, be located on the left wall in supercharging storehouse 7, or be integrated with supercharging storehouse 7 left walls, its diameter is greater than the diameter that advances mouth 4, and with to advance mouth 4 corresponding, inner walls buffer substrate tablet 3 is fan-shaped, be horizontally installed on spirally on the inner walls bus, its arc length is sixth to ten/one of housing 1 inner wall section girth, with the angle of housing 1 inwall air intake surface be 50 degree-70 degree; Flue gas cleaner inner walls 1, supercharging storehouse 7, injection spray pipe 2, wind-force buffer substrate tablet 15 all adopt novel antiacid anti-corrosion spray material processed.

The utility model has reached intended purposes, changed the practice of moist in the past deduster with the moisture film spray, adopted injection spray pipe 2 sprayings to form the technology of water smoke section, under the effect of wind-force buffer substrate tablet 15, reduce the speed of flow of flue gas, the increase flue gas contacts with alkaline water smoke, improve the dust-removal and desulfurizing effect, the combined dust-eliminating rate of boiler smoke is reached more than 95%, desulfurization degree reaches more than 85%.This flue gas cleaner is simple in structure, and service life is more than 10 years; Cost is low, and cost is 1/3rd of present various dedusters, and volume is little, and is easy for installation, and it is little to take up room, and is large medium-size boiler and thermal power plant, the matching used ideal equipment in cement plant.

Below in conjunction with accompanying drawing operation principle of the present utility model is elaborated.

Accompanying drawing 1 is the structural representation of atomizing gas cleaning apparatus.

Accompanying drawing 2 is configuration schematic diagram of one group of inner walls buffer substrate tablet of atomizing gas cleaning apparatus and injection spray pipe.

When the flue gas in the boiler enters flue gas cleaner through air-introduced machine by advancing mouth 4, at first be subjected to stopping of air inlet buffer substrate tablet 11 and change flow direction, flue gas by around enter the clarifier cavity, under the effect of inner walls buffer substrate tablet 3, wind speed is down to 1.5 meter per seconds by 5 meter per seconds, and formation eddy flow, water smoke with injection spray pipe 2 ejections fully contacts simultaneously, under the effect of eddy flow and centrifugal force, flue gas and inner walls and wind-force buffer substrate tablet 15 collide repeatedly, carry out dust-removal and desulfurizing, sulfur dioxide in the flue gas and alkaline water neutralization, become innocuous gas and discharge with outlet flue 5, flue dust and other impurity flow into dust stratification ponds 12 precipitations with drainpipe 6, can add again burning in the coal after pulling airing out, the water in dust stratification pond 12 flows into circulating water pool 13, send into supercharging storehouse 7 by water pump 14 and recycle, the Dust Capacity of circulating water pool 13 is big when need changing, and changes can enter sewer when the pH value test reaches discharge standard after.
