Description
Technical field
The present invention relates to a kind of cremate technology of funeral profession, specifically, relate to a kind of purification treatment device for incineration flue gas.
Background technology
At present, China's funeral profession all adopts in line mode to discharge cremate waste gas in the Cremation Machine overwhelming majority of usefulness, cremating, it is very serious to pollute, because the atmosphere pollution that produces of cremating had both comprised the inorganic pollutions such as flue dust, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, ammonia, mercury, comprise again the dioxin organic pollution materials.As effectively not controlled, certainly will cause the abominable destruction of severe contamination and the peripheral ecological environment of funeral place air." the national civil administration science and technology Long-and Medium-term Development planning outline (2009-2020) " that issue in 2009 is implemented, classify funeral and interment science and technology as giving priority to field, and classify " research of field of funeral and interment severe toxicity dioxin pollution thing emission-reduction technology ", " technical research of clean energy resource cremate remains " as great scientific and technological engineering.
Existing funeral profession incinerating smoke cleaning device mainly is the dry cleaning system take sack cleaner as chief component, and the system for wet purification take the water curtain sprinkling device as chief component.The shortcoming of prior art is: one, the soot dust granule thing can only be removed by the wet cleaning system take the water curtain sprinkling device as chief component, and a small amount of sour gas can not effectively be removed the dioxin organic pollution.Two, the dry cleaning system take sack cleaner as chief component does not have removal effect substantially for the sour gas pollutant.And because two types purifier inlet temperature (approximately below 500 ℃) on the low side, this temperature is exactly again synthetic needed temperature of dioxin-like chemical just, therefore, follow-up the total amount to be processed or dioxin-like chemical of discharging is bigger than normal, can not effectively purify the cremate flue gas.
Summary of the invention
Technical problem solved by the invention provides a kind of purification treatment device for incineration flue gas, can effectively remove acid inorganic pollution and dioxin organic pollution in the cremate flue gas simultaneously.
Technical scheme is as follows:
A kind of purification treatment device for incineration flue gas, comprise sack cleaner and air-introduced machine, also comprise chemicals dosing plant, blowing device, smoke combustion chamber, burner, condensate pipe, cool-heat-exchanger, remove acid system, separating dry space from moist space device, activated carbon powder storage tank and mixing chamber; It is inner that described condensate pipe is arranged on described cool-heat-exchanger, and described burner is arranged on the smoke combustion chamber; Described smoke combustion chamber is provided with entrance and exit, the outlet of described smoke combustion chamber is connected to the entrance of described cool-heat-exchanger by pipeline, the outlet of described cool-heat-exchanger connects described entrance except acid system by pipeline, described outlet except acid system connects the entrance of described separating dry space from moist space device by pipeline, the outlet of described separating dry space from moist space device is connected to the entrance of described mixing chamber by pipeline, described activated carbon powder storage tank is arranged on the described mixing chamber, the outlet of described mixing chamber is connected to by pipeline on the entrance of described sack cleaner, and the outlet of described sack cleaner is provided with air-introduced machine; The outlet of described chemicals dosing plant is connected to described except on the acid system by pipeline, the first outlet of described blowing device is connected to described except on the acid system by pipeline, and the second outlet of described blowing device is connected on the described mixing chamber by pipeline.

Further: described lye tank (vat) is provided with dosing mouth, and described tank diameter is provided with water supplement port.
Compared with prior art the technology of the present invention effect comprises:
1, in the prior art, the flue outlet temperature all is lower than 500 ℃, just directly flue gas is carried out quenching in the situation that do not install the smoke combustion chamber additional, and the effect of removing dioxin-like chemical is also not obvious.Among the present invention, install additional after the smoke combustion chamber, can effectively guarantee the chilling effect, the again fully burning of flue gas that flue is discharged, both prolonged the holdup time of flue gas at high-temperature area, imperfect combustion part is fully burnt, the cigarette temperature is raise again, be next step flue gas quenching, cross dioxin-like chemical more synthetic temperature province carried out sufficient place mat.
2, the present invention is provided with except acid system, mixing chamber and sack cleaner, under the acting in conjunction of activated carbon powder, can effectively remove acid inorganic pollution and dioxin organic pollution in the cremate flue gas simultaneously, makes purification more thorough more comprehensively.The scene has entrusted the relevant expert of national environmental protection section that it is carried out Contaminant measurement, and test result all reaches the funeral profession national standard.
3, the design of the separating dry space from moist space device among the present invention is very ingenious, and very crucial for whole purification process, and the dehydrating effect of separating dry space from moist space device will directly affect the removal efficiency of sack cleaner.If this device not, the cloth bag in the sack cleaner will be in dampness for a long time, and the blowback effect of air compressor machine will be had a greatly reduced quality.
4, the target contaminant that removes in the flue gas of the present invention is comprehensive, has both comprised conventional atmosphere inorganic pollution, such as flue dust, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, ammonia, mercury etc., comprises again the dioxin organic pollution materials.
5, has huge Social benefit and economic benefit.Social benefit: the pollution problem of funeral profession cremate technique always is the problem of the Chinese government and broad masses of the people's headache, and existing funeral and interment science and technology also is in the starting stage, also can't resolve the problem of environmental pollution that cremation of remains brings at present; Apparatus of the present invention can effectively be removed the cremate pollutant, take the lead in proposing in funeral profession take conventional pollutant and dioxin organic pollution as the main concept of removing object, for contribution has been made in the establishment of China BAT/BEP in this field.Economic benefit: according to " civil administration career development statistical report in 2009 " by the end of the end of the year in 2009,1729 in the total funeral parlor, the whole nation, 5123 of Cremation Machine, year cremate remains 454.2 ten thousand tools, the situation of post processing is installed according to current funeral profession, conservative prediction needs 4500 cover cremate flue gas after-treatment devices at least, and economic benefit and market prospects are very considerable.
