The Horizental showering Tower for purifying waste gas
Technical field
The utility model relates to a kind of emission-control equipment, specifically is used for waste gas is carried out the Tower for purifying waste gas of spray cleaning.
Background technology
At present, electroplating manufacture field,, using the spray Tower for purifying waste gas that harmful exhaust is carried out spray cleaning usually, thereby can avoid harmful exhaust directly to enter air and the environmental pollution that causes because electroplating assembly line can produce a large amount of harmful exhausts.Traditional spray Tower for purifying waste gas mainly adopts vertical structure, and height to having relatively high expectations of fabricating yard, therefore is difficult in indoor installation more than 5 meters usually.If this purifying column is installed in outdoor,, is prone in the purifying column freeze and causes and to use because winter temperature is lower.In addition; Traditional spray purification tower inner filtration layer and watertight layer are successively according to being disposed in order from bottom to top; There is spraying mechanism the filter course top, and waste gas is only done ascending motion in purifying column, can't carry out sufficient chemical reaction with filter course; Cause waste gas purification incomplete, thereby make exhaust purification efficiency relatively poor.
The utility model content
The problem that the utility model will solve provides a kind of Horizental showering Tower for purifying waste gas, adopts this purifying column, can it be installed in indoorly, and waste gas is fully purified in purifying column, has improved exhaust purification efficiency.
For addressing the above problem, adopt following scheme:
The Horizental showering Tower for purifying waste gas of the utility model comprises tower body, is characterized in that said tower body is horizontal layout, and the tower body bottom is equipped with the aqua storage tank that is used to hold spray liquid.The two ends of tower body have air outlet and air inlet respectively, and air inlet is connected with blower fan.Be provided with vertical absorption exchange layer from the air intake oral-lateral segment distance of whenever being separated by in the tower body; The height of absorption exchange layer is less than the height of tower body inner chamber; And the parallel each other staggered layout up and down that is; Between making at the bottom of bottom and the tower of absorption exchange layer or leave spacing between top and cat head, baffle plate is arranged in the spacing.Vertical watertight layer is arranged in the tower body near air outlet one side, and the windward side of absorption exchange layer and watertight layer is provided with spraying mechanism.Be connected with circulating pump between spraying mechanism and the aqua storage tank, spraying mechanism, aqua storage tank and circulating pump constitute the spray closed circuit.
The further improvement project of the utility model is that said absorption exchange layer and watertight layer are made into movable drawing and pulling type structure, thereby can it be pulled out outside tower body, is convenient to clean and change.Described movable drawing and pulling type structure can be tabular framework, and the filling polypropylene divides water polo in plate-shaped frame.
The further improvement project of the utility model is that said circulating pump is the corrosion resistance circulating pump, thereby can avoid being increased service life by the spray liquid corrosion.
Spraying mechanism described in the aforementioned schemes is made up of some parallel pipelines, and is communicated with through pipeline between adjacent channel, thereby can make the spray piping in the tower body constitute an integral body, has reduced the usage quantity of circulating pump.
Adopt such scheme, have the following advantages:
Because the tower body of the Horizental showering Tower for purifying waste gas of the utility model adopts horizontal type structure, less demanding to the installing space height, therefore can it be installed in indoor, thereby can avoid purifying column inner icing in the winter time and the problem that can't use.In addition; Because the inner absorption exchange layer of the Horizental showering Tower for purifying waste gas of the utility model adopts staggered up and down layout, waste gas can be done the labyrinth type operation in purifying column, increased the time of staying of waste gas in tower; Make the chemical reaction of spray absorption more thorough, thereby improved purification efficiency.

The specific embodiment
As depicted in figs. 1 and 2, the Horizental showering Tower for purifying waste gas of the utility model comprises tower body 3, and this tower body 3 is horizontal layout, and tower body 3 bottoms are equipped with aqua storage tank 7, and this aqua storage tank 7 is used to hold spray liquid.The two ends of tower body 3 have air outlet 1 and air inlet 6, and air inlet 6 is connected with blower fan 8, and air outlet 1 can be connected with ventilation shaft.Be provided with vertical absorption exchange layer 4 from the air inlet 6 sides segment distance of whenever being separated by in the tower body 3, the quantity of absorption exchange layer 4 is 3 in the present embodiment, and the distance between every adjacent two absorption exchange layers equates.The height of absorption exchange layer 4 is less than the height of tower body inner chamber; And the parallel each other staggered layout up and down that is; Make from the bottom of first absorption exchange layer of air inlet 6 sides with at the bottom of the tower between, all leave spacing between between the top and cat head of second absorption exchange layer, at the bottom of the bottom of the 3rd absorption exchange layer and the tower, baffle plate is all arranged in the spacing.In order to make gas flow smooth and easy, can increase the time of staying of gas in purifying column again, 1/2 of the approximate tower body 3 inner chamber longitudinal sections of size, longitudinal section of said absorption exchange layer 4.Vertical watertight layer 2 is arranged in the tower body 3 near air outlet 1 one sides, and the windward side of absorption exchange layer 4 and watertight layer 2 is provided with spraying mechanism 5.Spraying mechanism 5 in the present embodiment is made up of some laterally parallel pipelines; And be communicated with through straight tube and/or bend pipe between adjacent channel; Between the adjacent absorption exchange layer or absorption exchange layer also is communicated with pipeline between the watertight layer through straight tube and/or bend pipe, thereby can make integral body of spray piping formation of tower body inside.Between said spraying mechanism 5 and aqua storage tank 7, be connected with circulating pump 9, this circulating pump 9 is the corrosion resistance circulating pump preferably.Spraying mechanism 5, aqua storage tank 7 and circulating pump 9 constitute the spray closed circuit.
Wherein, said absorption exchange layer 4 is movable drawing and pulling type structure with watertight layer 2, thereby can it be pulled out outside tower body, is convenient to clean and change.Absorption exchange layer 4 in the present embodiment is plate-shaped frame with watertight layer 2, and the filling polypropylene divides water polo in plate-shaped frame.
