Abstract
The invention discloses a kind of exhaust gas cleaner, comprise one-level fine ceramic filter, urea water jet head sets, secondary stoneware filter, dust collection chamber and dust discharging tube; Described one-level fine ceramic filter is arranged on the through hole on the top of dust collection chamber; Described offgas outlet pipe is right-angle elbow pipe, is also provided with urea water jet head sets and secondary stoneware filter at the horizontal segment of right-angle elbow pipe.The present invention arranges two-stage purification device, with the catalyst of denitration reaction on secondary stoneware filter, and urea water jet head sets is provided with before secondary stoneware filter, before tail gas arrives secondary stoneware filter, urea water fully mixes 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 is mixed with urea water by urea water jet head sets, carry out combined desulfurization and denitration reaction finally by secondary stoneware filter, thus reach the effect of tail gas secondary purification.
Description
Technical field
The present invention 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 directly having influence on people, the numerical value of PM2.5 constantly rises, containing pollutants such as solid particle, oxysulfide, nitrogen oxide in the tail gas of automobile, boats and ships, power plant discharge, they are the key factors affecting air quality, before exhaust emissions to air, harmful substance can be removed, then 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, the poor quality fuel oil of burning, and tail gas is directly discharged in air, huge to environmental hazard.Sulfur and nitrogen oxides can not be made in some tail gas unit can not fully to mix with reactant, and in denitrification process, also can be attached to catalyst surface because of dust make catalyst poisoning, cause desulfurization and denitrification reaction cannot sufficient reacting.
Summary of the invention
For solving the problems referred to above that prior art exists, the present invention will design a kind of exhaust gas processing device effectively removing the harmful substance in tail gas.
To achieve these goals, technical scheme of the present invention is as follows: a kind of exhaust gas processing device, comprises inlet exhaust gas pipe, one-level fine ceramic filter, urea water jet head sets, secondary stoneware filter, offgas outlet pipe, dust collection chamber and dust discharging tube; There are three through holes in described dust collection chamber, and PATENT left side via is connected with inlet exhaust gas pipe, the through hole on top is connected with offgas outlet pipe, the through hole of bottom is connected with dust discharging tube; Described one-level fine ceramic filter is arranged on the through hole on the top of dust collection chamber; Described offgas outlet pipe is right-angle elbow pipe, is also provided with urea water jet head sets and secondary stoneware filter at the horizontal segment of right-angle elbow pipe; Described urea water jet head sets is positioned at the front of secondary stoneware filter; With the catalyst of denitration reaction on described secondary stoneware filter.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention arranges two-stage purification device, first class purification device is fine pore ceramic filter, secondary device is comparatively gross porosity ceramic filter, with the catalyst of denitration reaction on secondary stoneware filter, and before secondary stoneware filter, be provided with urea water jet head sets, before tail gas arrives secondary stoneware filter, urea water fully mixes 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 is mixed with urea water by urea water jet head sets, combined desulfurization and denitration reaction is carried out finally by secondary stoneware filter, thus reach the effect of tail gas secondary purification.
2, the tail gas that automobile, boats and ships, power plant etc. produce can process by the present invention, solves a difficult problem for the aging of catalyst and poisoning problem, decreases air pollution to a greater extent.
3, the pollutants such as the dust in tail gas, oxysulfide, nitrogen oxide can effectively be removed by the present invention, but also effectively avoid catalyst poisoning.
4, the present invention can according to the size of size determination one-level fine ceramic filter filter opening needing filter dust particle, almost can filter out dust completely.
5, in the combined desulfurization and denitration reaction in secondary stoneware filter of the present invention, in the scope that temperature is suitable, desulfuration efficiency can reach about more than 90%, and denitration efficiency can reach about more than 95%.
Accompanying drawing explanation
The present invention is drawings attached 1 only, wherein:
Fig. 1 is structural representation of the present invention.
In figure: 1, inlet exhaust gas pipe, 2, one-level fine ceramic filter, 3, urea water jet head sets, 4, secondary stoneware filter, 5, offgas outlet pipe, 6, dust collection chamber, 7, dust discharging tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.As shown in Figure 1, a kind of exhaust gas processing device, comprises inlet exhaust gas pipe 1, one-level fine ceramic filter 2, urea water jet head sets 3, secondary stoneware filter 4, offgas outlet pipe 5, dust collection chamber 6 and dust discharging tube 7; There are three through holes in described dust collection chamber 6, and PATENT left side via is connected with inlet exhaust gas pipe 1, the through hole on top is connected with offgas outlet pipe 5, the through hole of bottom is connected with dust discharging tube 7; Described one-level fine ceramic filter 2 is arranged on the through hole on the top of dust collection chamber 6; Described offgas outlet pipe 5 is right-angle elbow pipe, is also provided with urea water jet head sets 3 and secondary stoneware filter 4 at the horizontal segment of right-angle elbow pipe; Described urea water jet head sets 3 is positioned at the front of secondary stoneware filter 4; With the catalyst of denitration reaction on described secondary stoneware filter 4.
When the present invention works, the tail gas produced by engine, diesel engine enters from device exhaust inlet tube 1, the dust in tail gas is filtered out through one-level fine ceramic filter 2, again when urea water jet head sets 3, the tail gas of first class purification fully mixes with urea water, and the stoneware filter 4 flow to together with desulphurization denitration catalyst, combined desulfurization and denitration reaction occurs under stoneware filter 4 is as the condition of catalyst carrier, and the tail gas through secondary purification is disposed in air by offgas outlet pipe 5.The dust that one-level fine cleaner filters out drops to dust collection chamber 6, finally by dust discharging tube 7 emission treatment.
