Abstract
The utility model relates to a venturi sprinkling and gas washing device which is arranged in a boiler flue. The venturi sprinkling and gas washing device is characterized in that a spraying head of the device is composed of a water sprinkling spraying head on the front of a venturi throat part which is arranged on an axle line in a venturi pipe and a spiral spraying head which is wound around the water sprinkling spraying head. In this way, the dust of smoke gas which enters the venturi pipe can be firstly removed by water mist which is sprayed by the spiral spraying head, and harmful gas is absorbed by the water mist. Then, the dust is removed by the water drop of the water sprinkling spraying head, and the harmful gas is also absorbed by the water drop. Secondary gas and water momentum exchange is generated. The utility model has the advantages of simple structure, easy production, installation and maintenance, high dust removing and gas washing efficiency and good adaptability.
Description
The utility model relates to environmental protection equipment, particularly is the dedusting of a kind of sprinkling can type venturi water spray, air-washer.
The dedusting of sprinkling can type venturi water spray, air-washer are mounted in a kind of water injector in the venturi reducing pipe, and the flue that is used for Industrial Boiler eliminates smoke and dedusting.Because the diffusing shape water column of the sprinkling can type fountain head ejection of the dedusting of existing sprinkling can type venturi water spray, air-washer is difficult to be broken through by swiftly flowing flue gas in venturi throat, not reaching fully, gas, the exchange of hydrodynamic(al) amount reach the standard to the absorption of flue dust and pernicious gas, thereby its result of use is not good, can not reach environmental requirement.
The purpose of this utility model is exactly that a kind of dedusting of sprinkling can type venturi water spray, air-washer with higher dedusting, gas washing efficient will be provided.
For this reason and the dedusting of sprinkling can type venturi water spray, the air-washer of invention, by Venturi tube with place the fountain head before the Venturi tube throat to form, and fountain head is by placing in the Venturi tube trickle shower nozzle before the venturi throat on the axis and forming around the spiral nozzle of trickle shower nozzle.Spiral nozzle is uniform, is advisable with eight.
When using the utility model, the flue gas that flows is at first broken through by the vaporific water droplet of high speed that spiral nozzle sprays, flue gas is atomized and dedusting and absorption pernicious gas first, flue gas after the atomizing again high velocity stream through venturi throat, break through the water droplet under the pouring of trickle shower nozzle, produce the exchange of secondary gas, hydrodynamic(al) amount with it, and to flue gas ash removal with adsorb pernicious gas once more, flue dust in the flue gas and pernicious gas are in a liquid state drain.
The utility model is simple in structure, easily processing, installation and maintenance, and its dedusting, gas washing efficient can be widely used in dedusting, the gas washing system of large and medium-sized boiler and medicine, chemical industry, health industry than the existing apparatus height, more can be in order to transform existing equipment.The smoke evacuation of the spreader stoker boiler behind use the utility model can reach the one-level environmental requirement.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Shown in Figure 1, the utility model is by Venturi tube 1 and place the trickle shower nozzle 2 on the venturi throat 4 preceding axis and form around trickle shower nozzle 2 eight uniform spiral nozzles 3.
Claims (2)
1, a kind of sprinkling can type venturi water spray dedusting, air-washer, by Venturi tube with place the fountain head before the Venturi tube throat to form, it is characterized in that said fountain head is by placing in the Venturi tube on the axis trickle shower nozzle before the venturi throat and forming around the spiral nozzle of trickle shower nozzle.
2, sprinkling can type venturi water spray according to claim 1 dedusting, air-washer is characterized in that said spiral nozzle around the trickle shower nozzle is uniform eight.
