A kind of Tower for purifying waste gas
Technical field
The utility model relates to a kind of Tower for purifying waste gas, belongs to off-gas cleaning equipment field.
Background technology
Along with China's food service industry and food and restaurant service industry develop rapidly, the annual discarded edible oil and fat that produce are also more and more, and " recycling " production biodiesel of discarded edible oil and fat is a kind of effective ways of containment " poison oil ".But in biodiesel leaching process, conventionally can discharge all types of industries waste gas, if can not carry out effective purified treatment, easily cause air pollution, and then destroyed ecological environment.
On August 17th, 2011, Chinese invention patent application CN102151451A discloses a kind of Multifunctional waste gas purification tower and has comprised housing, by the acid-base value setting gradually from bottom to top, correct district, liquid pouring dedusting area, gas dehumidification district, pernicious gas adsorption zone, be matched with acid-base value and correct the acid-alkali-corrosive-resisting water pump of Yu Yelin dedusting area, district, liquid pouring is provided with exhaust gas inlet below dedusting area, be positioned at the unlimited exhaust outlet in tower body top, in tower body housing, establish the sieve tray of separating each district, be positioned at the dust emission mouth of tower body bottom.But waste gas carries out entering fast and drenching dedusting area by liquid after purifying column in its course of work, cause the dust removing effects of liquid pouring dedusting area poor, directly affect the purification process of postorder.
On January 12nd, 2011, Chinese utility model patent CN201701859U discloses a kind of purifying column, the tower body that comprises bottom inlet, band gas outlet, top, tower body inside is from bottom to top disposed with lower retaining ring, turbulent column plate, tarpaulin, annular atomizer group one, particulate adsorption layer, annular atomizer group two, high speed dewatering layer.This purifying column arranges a plurality of turbulent column plates in tower body upsets waste gas, slow down exhaust-gas flow speed, improve clean-up effect, but because its turbulent column plate adopts the sheet material of real face, stopped to a certain extent exhaust-gas flow, disorderly efficiency is very low, and disorderly effect is poor, particularly, when processing exhausted air quantity is larger, its impact is more obvious.In addition, in the winter time or extremely frigid zones, on turbulent column plate, easily form and freeze, also can affect the disorderly effect of waste gas.
Utility model content
The purpose of this utility model is to provide a kind of Tower for purifying waste gas, to solve Tower for purifying waste gas of the prior art, and turbulent weak effect, the technical problem that waste gas purification effect is undesirable.

The beneficial effects of the utility model are: with turbulent tracheae, replace existing turbulent column plate, slow down but do not stop flowing of waste gas, improved turbulent effect, for postorder purifies, lay the first stone; By fumarole, erupt gas acceleration waste gas and upset, efficiency that raising is turbulent.
As improvement, the angle of described turbulent tracheae itself and horizontal plane is for being more than or equal to-4 ° and be less than or equal to 4 ° of settings, the turbulent better effects if of its waste gas.
As further improvement, described turbulent tracheae is some, and it is different in size, to improve the turbulent efficiency of waste gas.
As further improving, described turbulent tracheae is selected hot gas or gas at normal temperature air feed, to adapt to the work requirements in Various Seasonal or area.
In order to improve operating efficiency and the effect of scrubber layer, as further improving, described scrubber layer comprises shower and hollow ball filler again; Described shower is positioned at hollow ball filler top, along tower body inwall, surrounds annular, and body is provided with a plurality of spray apertures.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, Tower for purifying waste gas of the present utility model, comprise tower body 1, the top of tower body 1 is provided with exhaust outlet 2, the bottom of tower body 1 is provided with water tank 4, tower body 1 inside is provided with aerosol separating layer 5, adsorption layer 6, scrubber layer, filter course 9 from top to bottom, is provided with air inlet 3 and the turbulent tracheae 10 being connected with pipeline between water tank 4 and filter course 9.
Aerosol separating layer 5 in tower body 1 is used metal many-sided ball filler, is conducive to separated air and mist, and aerosol separating layer 5 is connected with the gas outlet 2 at tower body 1 top.
Adsorption layer 6 is positioned at aerosol separating layer 5 belows for adopting the materials such as active carbon to fill.
Scrubber layer is positioned at adsorption layer 6 belows and comprises shower 7 and hollow ball filler 8, shower 7 is positioned at hollow ball filler 8 tops, along tower body 1 inwall, surround annular, body is provided with a plurality of spray apertures, and shower is through piping 12, water pump 13 and be connected water tank 4 and carry out periodical feeding.
Filter course 9 is positioned at scrubber layer 6 belows and consists of multiple filtration ball.
Turbulent flow tracheae 10 is positioned near tower body filter course 9 belows, inlet gas 3, is connected with gas supply pipe 11; Turbulent flow tracheae 10 can arrange many, and it is different in size, and body surface is provided with irregular fumarole; Turbulent flow tracheae 10 can arrange at a certain angle, and it is more than or equal to-4 ° and be less than or equal to 4 ° for the best with the angle of horizontal plane; Turbulent flow tracheae 10 can be selected supply hot gas or gas at normal temperature according to season or regional variations in temperature; Turbulent flow tracheae 10 thicknesses are made according to the size of the volume of tower body 1 and air inlet 3.
Water tank 4 is positioned at tower body 1 below, comprises water inlet 14, sewage draining exit 15.Sewage draining exit 15 is arranged on water tank bottom, and water inlet 14 is arranged on the below of air inlet 3.Water tank 4 connects water pump 13 and supplies water to shower 7 through pipeline 12.
The course of work of the present utility model is as follows:
1) waste gas enters in purifying column by air inlet 3, contacts with turbulent tracheae 10, and a plurality of turbulent tracheaes 10 slow down flowing of waste gas, and the gas that turbulent tracheae 10 gushes out is simultaneously upset waste gas, forms turbulent flow.
2) waste gas that turbulent flow is crossed is slowly by filter course 9, and the multiple filtration ball on filter course 9 filters waste gas comprehensive engagement, carries out first class purification.
3) by the waste gas after first class purification, enter after scrubber layer, scrubber layer hollow ball filler 8 is used waste gas and the abundant haptoreaction of cleaning solution by polyhedron globe, and waste gas is carried out to secondary purification.
