Abstract
The utility model discloses a tail gas cleanup device which comprises a primary fine ceramic filter, a urea water nozzle set, a secondary coarse ceramic filter, a dust collecting chamber and a dust discharging pipe, wherein the primary fine ceramic filter is installed at a through hole of the upper part of the dust collecting chamber; a tail gas outlet pipe is a right-angle elbow pipe, and the horizontal segment of the right-angle elbow pipe is also provided with the urea water nozzle set and the secondary coarse ceramic filter. The two levels of cleanup devices are arranged, a denitration reaction catalyst is arranged on the secondary coarse ceramic filter, and the front of the secondary coarse ceramic filter is provided with the urea water nozzle set; before the tail gas reaches the secondary coarse ceramic filter, urea water is fully mixed with the tail gas; dust in the tail gas discharged from a smoke discharging pipe is filtered out through the primary fine ceramic filter, and the dust is collected to be discharged; the tail gas after primary cleanup is mixed with the urea water through the urea water nozzle set and finally is subjected to combined desulfurization and denitration reaction through the secondary coarse ceramic filter, and therefore, the secondary cleanup effect of tail gas is achieved.
Description
Technical field
The utility model relates to industrial air purifying process, particularly a kind of exhaust gas cleaner.
Background technology
Environmental problem is the problem that the whole world is all being paid close attention to, the quality of air quality is also the Health and Living quality that directly has influence on people, the numerical value of PM2.5 is constantly soaring, in the tail gas of automobile, boats and ships, power plant discharge, contain the pollutants such as solid particle, oxysulfide, nitrogen oxide, they are the key factors that affects air quality, can, at exhaust emissions to before atmosphere, harmful substance be removed, the improvement of air quality is improved a lot.
Existing boat diesel engine, power plant seldom have exhaust gas processing device, especially boat diesel engine, and the poor quality fuel oil of burning, tail gas is directly discharged in atmosphere, huge to environmental hazard.In some tail gas unit, can not make sulfur and nitrogen oxides can not fully mix with reactant, and in denitrification process, also can be attached to catalyst surface because of dust and make catalyst poisoning, cause the desulfurization and denitrification reaction cannot sufficient reacting.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model will design a kind of exhaust gas processing device that can effectively remove the harmful substance in tail gas.
To achieve these goals, the technical solution of the utility model is as follows: a kind of exhaust gas processing device, comprises tail gas inlet tube, one-level fine ceramic filter, urea water jet head sets, secondary stoneware filter, tail gas outlet, dust collection chamber and dust discharge pipe; There are three through holes in described dust collection chamber, and PATENT left side via is connected with tail gas inlet tube, the through hole on top is connected with tail gas outlet, the through hole of bottom is connected with dust discharge pipe; Described one-level fine ceramic filter is arranged on the through hole on the top of dust collection chamber; Described tail gas outlet is right-angle elbow pipe, at the horizontal segment of right-angle elbow pipe, urea water jet head sets and secondary stoneware filter is also installed; Described urea water jet head sets is positioned at the front of secondary stoneware filter; On described secondary stoneware filter with the catalyst of denitration reaction.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model arranges two-stage purification device, first class purification device is fine pore ceramic filter, secondary device is compared with gross porosity ceramic filter, on secondary stoneware filter with the catalyst of denitration reaction, and be provided with urea water jet head sets before secondary stoneware filter, tail gas arrives before secondary stoneware filter, urea water is fully mixed with tail gas, the tail gas of being discharged by smoke exhaust pipe is by one-level fine ceramic filter, filter out dust, and discharge after dust is collected, tail gas after first class purification mixes with urea water by urea water jet head sets, finally carry out combined desulfurization and denitration reaction by secondary stoneware filter, thereby reach the effect of tail gas secondary purification.
2, the utility model can be processed the tail gas of the generations such as automobile, boats and ships, power plant, has solved a difficult problem for the aging and poisoning problem of catalyst, has reduced to a greater extent air pollution.
3, the utility model can effectively be removed the pollutants such as the dust in tail gas, oxysulfide, nitrogen oxide, but also has effectively avoided catalyst poisoning.
4, the size that the utility model can filter dust granule according to need is determined the size of one-level fine ceramic filter filter opening, almost can filter out dust completely.
5, in the combined desulfurization and denitration in secondary stoneware filter of the present utility model reaction, in the suitable scope of temperature, desulfuration efficiency can reach approximately more than 90%, and denitration efficiency can reach approximately more than 95%.
Brief description of the drawings
Only 1 of drawings attached of the utility model, wherein:
Fig. 1 is structural representation of the present utility model.
In figure: 1, tail gas inlet tube, 2, one-level fine ceramic filter, 3, urea water jet head sets, 4, secondary stoneware filter, 5, tail gas outlet, 6, dust collection chamber, 7, dust discharge pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1, a kind of exhaust gas processing device, comprises tail gas inlet tube 1, one-level fine ceramic filter 2, urea water jet head sets 3, secondary stoneware filter 4, tail gas outlet 5, dust collection chamber 6 and dust discharge pipe 7; There are three through holes in described dust collection chamber 6, and PATENT left side via is connected with tail gas inlet tube 1, the through hole on top is connected with tail gas outlet 5, the through hole of bottom is connected with dust discharge pipe 7; Described one-level fine ceramic filter 2 is arranged on the through hole on the top of dust collection chamber 6; Described tail gas outlet 5 is right-angle elbow pipe, at the horizontal segment of right-angle elbow pipe, urea water jet head sets 3 and secondary stoneware filter 4 is also installed; Described urea water jet head sets 3 is positioned at the front of secondary stoneware filter 4; On described secondary stoneware filter 4 with the catalyst of denitration reaction.
When the utility model work, the tail gas being produced by engine, diesel engine enters from device exhaust inlet tube 1, the dust filtering out in tail gas through one-level fine ceramic filter 2, while passing through again urea water jet head sets 3, the tail gas of first class purification fully mixes with urea water, and flow to together the stoneware filter 4 with desulphurization denitration catalyst, and under the condition at stoneware filter 4 as catalyst carrier, there is combined desulfurization and denitration reaction, be disposed in atmosphere by tail gas outlet 5 through the tail gas of secondary purification.The dust that one-level fine cleaner filters out drops to dust collection chamber 6, finally by dust discharge pipe 7 emission treatment.
