A kind of durable and efficient neutralizing tower
Technical field
The utility model relates to a kind of purifying processing device that absorbs waste gas
Background technology
Tradition waste gas absorption tower generally adopts spray mode to neutralize absorption to acid or alkaline waste gas, waste gas from bottom to top single file passes through spray-absorption device, then through de-liquid net dehydrating demisting, directly enter atmosphere, restriction due to its spray equipment structure, though its clean-up effect is good, but thorough not, easily there is waste gas residual, environment is exerted an influence.
Utility model content
Thorough not in order to overcome prior art purification, easily produce residual deficiency, the utility model provides a kind of durable and efficient neutralizing tower.
The utility model solves the technical scheme that its technical problem adopts:
A kind of durable and efficient neutralizing tower, comprise the tower body with upper and lower two observation windows, described tower body bottom is provided with air inlet, in the tower body of air inlet top, be provided with waste gas is carried out to preliminary packing area of filtering, described tower body bottom is also connected with tank, the inner correspondence of tower body of two observation window top positions is provided with two-stage high-pressure nozzle, described high-pressure nozzle annular configuration, the nozzle of high-pressure nozzle is its perpendicular bisector tangential tilt 10~20 degree relatively, the water curtain that spray is formed is vortex heavy curtain shape, and the incline direction of upper and lower two-stage high-pressure nozzle is contrary, tower body arranged outside has water pipe and the water circulating pump that the water in tank is caused to high-pressure nozzle, tower body top is provided with exhaust outlet.
In order to make exhaust more smooth and easy, described tower body top is provided with the air exhauster that promotes exhaust.
For the gas of taking is carried out to dehydrating demisting, the air exhauster at described tower body top below is provided with de-liquid net.
For fear of outside rainwater from exhaust outlet, enter in tower body, on the exhaust outlet at described tower body top, be provided with taper protective cover.
For the ease of processing, and the durability of raising neutralizing tower, described tower body is the cylindrical tower body of PPR material, its top dwindles to draw in and forms exhaust outlet.
The beneficial effects of the utility model are: high-pressure nozzle annular configuration, and tangential tilt, the contact-making surface of waste gas and water curtain is increased, can form certain air-flow guiding simultaneously and sweep along effect, improved the purification efficiency of waste gas, waste gas absorption rate can reach more than 98%, toxic emission after purification, well below national standard, has been eliminated the pollution to air substantially, scientific and reasonable for structure, be convenient to produce, safeguard and clean, improved the durability of neutralizing tower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
The specific embodiment
With reference to Fig. 1, a kind of durable and efficient neutralizing tower of the present utility model, comprise the tower body 1 with upper and lower two observation windows 11, described tower body 1 bottom is provided with air inlet 12, in the tower body 1 of air inlet 12 tops, be provided with waste gas is carried out to preliminary packing area 13 of filtering, described tower body 1 bottom is also connected with tank 14, the inner correspondence of tower body 1 of two observation window 11 top positions is provided with two-stage high-pressure nozzle 15, described high-pressure nozzle 15 annular configuration, the nozzle of high-pressure nozzle 15 is its perpendicular bisector tangential tilt 10~20 degree relatively, the water curtain that spray is formed is vortex heavy curtain shape, and the incline direction of upper and lower two-stage high-pressure nozzle 15 is contrary, tower body 1 arranged outside has water pipe 16 and the water circulating pump 17 that the water in tank 14 is caused to high-pressure nozzle 15, tower body 1 top is provided with exhaust outlet 18.
The nozzle of high-pressure nozzle 15 is obliquely installed, and is conducive to increase the residence time of current in tower body 1, increases the contact area of waste gas and current, can form certain air-flow simultaneously and guide and sweep along effect.The setting of two-stage high-pressure nozzle 15, makes the absorptivity of waste gas higher.
In order to make exhaust more smooth and easy, described tower body 1 top is provided with the air exhauster 19 that promotes exhaust.
For the gas of taking is carried out to dehydrating demisting, reduce the impact of moisture on air exhauster 19 simultaneously as far as possible, air exhauster 19 belows at described tower body 1 top are provided with de-liquid net.
For fear of outside rainwater from exhaust outlet 18, enter in tower body 1, on the exhaust outlet 18 at described tower body 1 top, be provided with taper protective cover 2.
For the ease of processing, and the durability of raising neutralizing tower, described tower body 1 is the cylindrical tower body of PPR material, its top dwindles to draw in and forms exhaust outlet 18.
Waste gas is from air inlet 12 enters tower body 1, and through packing area, 13 tentatively filter, then up under the power-assisted of air exhauster 19, and the water curtain forming through upper and lower two-stage high-pressure nozzle 15 purifies and absorbs, and after de-liquid net dehydrating demisting, from exhaust outlet 18, discharges.
Certainly, the utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should be within its protection domain.
