Abstract
The utility model relates to a dedusting device, particularly to a water film dedusting device for boilers, which belongs to the technical field of dedusting equipment. The dedusting device is divided into a water film generator, a water tank, etc. A smoke inlet is arranged on the upper part of a casing, a gas outlet is arranged on one side of the casing, and a water tank is arranged in the casing at the lower part. A plurality of baffle plates distributed in a crossed mode are arranged on the upper part of the casing, and the water film generator is arranged between the baffle plates. Water in the water tank is changed into steam by negative pressure produced by an induced draft fan and the heat of smoke, and a water film is produced and mixed with the smoke, so dust particles and sulphur dioxide are removed from the smoke. The utility model solves the problems that the existing dedusting methods using water films formed by spraying water have unsatisfactory dedusting and desulfurization effects, require high operation cost and cause environment pollution. While in use, the dedusting device does not need to continuously spray water, which wastes a large quantity of water and causes secondary pollution. The dedusting rate can reach 99.3 percents, and the desulfurization rate can reach more than 80 percents. The utility model is particularly suitable for dedusting and desulfurizing boiler smoke.
Description
Technical field:
The utility model relates to a kind of dust arrester, is specifically related to a kind of boiler water film dust arrester, belongs to the cleaner technical field.
Background technology:
Boiler is an industrial production, and the main heating equipment of domestic life aspect uses very generally, but contained dust and sulfur dioxide in the flue gas that boiler emission goes out also is one of the primary pollution source that must control of environmental protection.For a long time, in the employed cleaner of boiler smoke dedusting, in the majority with the double-tower type water dust scrubber, the operation principle of double-tower type water dust scrubber is by the formed moisture film of the water of continuous spray, reach dust in flue gas is removed, contained sulfur dioxide is carried out the purpose of desulfurization.But this water dust scrubber is not ideal to dedusting, the desulfurized effect of boiler smoke, and there still have certain dust and sulfur dioxide to arrive with fume emission to be aerial, causes environmental pollution; And water operating cost in the process that constantly sprays is very high, and the overhead cost of enterprise is increased.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, operating cost is low, dedusting, the boiler water film dust arrester that desulfurized effect is good, easy to install.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of boiler water film dust arrester, it is by housing, advance mouth, dividing plate, moisture film generator, gas outlet and pond constitute, it is characterized in that: the top of housing is provided with into mouth, and a side of housing is provided with the gas outlet, and the below of enclosure interior is provided with the pond, the top in pond is provided with the dividing plate that is interspersed, and is wherein advancing between two dividing plates of mouth one side the moisture film generator is housed.Described moisture film generator is one to be the tube at 90 ° of angles, and the port of export of its underpart is equipped with anemostat, and the diameter of anemostat is greater than the diameter of the tube that is 90 ° of angles.
The utility model beneficial effect compared with prior art is:
This boiler water film dust arrester is provided with the pond below device case inside, above the pond, be provided with mouth and moisture film generator, during work, by the negative pressure of air-introduced machine work generation and the self heat of flue gas, make the water in pond form steam and form moisture film, make it fully to mix, and dust granules in the flue gas and sulfur dioxide are removed with flue gas.Do not need a large amount of water constantly to spray in the entire work process, it is undesirable to have solved water film dedusting, desulfurized effect that existing employing water spray forms, and water constantly to spray operating cost very high, cause environmental pollution problems.This boiler water film dust arrester does not have sewage discharge, the secondary pollution that does not cause, and efficiency of dust collection can reach 99.3%, and desulfuration efficiency can reach more than 80%.
Description of drawings:
Fig. 1 is the sectional structure schematic diagram of boiler water film dust arrester;
Fig. 2 is the structural representation of the moisture film generator of boiler water film dust arrester.
Among the figure: 1, housing, 2, advance mouth, 3, dividing plate, 4, the moisture film generator, 5, the gas outlet, 6, the pond, 7, anemostat.
The specific embodiment:
This boiler water film dust arrester by housing 1, enter mouth 2, dividing plate 3, moisture film generator 4, gas outlet 5 and pond 6 and constitute, the top of housing 1 is provided with into mouth 2, one side of housing 1 is provided with gas outlet 5, the below of housing 1 inside is provided with pond 6, the top in pond 6 is provided with a plurality of dividing plates that are interspersed 3, and dividing plate 3 is divided into a plurality of independent but spaces of communicating with the inner space of housing 1.These by be divided into a plurality of independent of dividing plate 3 but its effect of space that communicate be, prevent to enter flue gas in the housing 1 under the suction function of air-introduced machine (drawing among the figure), directly be discharged from and do not reach the purpose of dust-removal and desulfurizing.Between two dividing plates 3 that advance mouth 2 one sides in housing 1 moisture film generator 4 is housed, moisture film generator 4 is one to be the tube at 90 ° of angles, the port of export of its underpart is equipped with anemostat 7, the diameter of anemostat 7 makes the stairstepping (referring to accompanying drawing 1-2) of the port of export formation of moisture film generator 4 to external diffusion greater than the diameter of the tube that is 90 ° of angles.
During the utility model work, by advancing flue-gas temperature that mouth 2 enters up to 230 ℃, the flue gas that contains dust granules and sulfur dioxide is directly pounced on the water surface in pond 6 after entering the space that is formed by dividing plate 3 in the housing 1, and high temperature dust granules bigger in the flue gas directly falls into pond 6; Simultaneously the water in the pond 6 is again by under the effect that is installed in negative pressure that the housing 1 outer air-introduced machine work that communicates with gas outlet 5 produced and cigarette temperature, form steam and rise and form moisture film, with advance the flue gas that mouth 2 enters and mix, dust granules smaller in the flue gas and sulfur dioxide are incorporated in the moisture film, finish the dust-removal and desulfurizing first time of flue gas.
Meanwhile, under the effect of air-introduced machine, enter in the housing 1 and finished for the first time that the flue gas of dust-removal and desulfurizing is entered by dividing plate 3 formed another spaces by moisture film generator 4, and after the port of the anemostat 7 of moisture film generator 4 forms diffusion, directly pounce on the water surface in pond 6.With in like manner last, heat energy in the flue gas enters in the water in pond 6 and produces steam and rises and form moisture film, the flue gas of dust-removal and desulfurizing mixes once more with finishing for the first time, dust granules trickleer in the flue gas and sulfur dioxide are carried out the secondary removing, make it to incorporate in the pond 6, finish the clean gas of secondary removing and arranged to atmosphere by gas outlet 5, whole dust-removal and desulfurizing work is finished.In the whole dust-removal and desulfurizing course of work, do not need the continuous spray of big water gaging, the secondary pollution that does not also have sewage discharge and caused, efficiency of dust collection can reach 99.3%, and desulfuration efficiency can reach more than 80%.
