Abstract
The present invention discloses a fume purifying agent used for eliminating smoke, dedusting and desulfurizing, which is composed of the following components: 42 to 47 wt% of alkylphenol polyoxyethylene, 45 to 50 wt% of sodium carbonate, and 8 to 10 wt% of anhydrous sodium sulfate. The present invention has the advantages of good desulfurizing effect, wide application range, etc., the Ringelman blackness can reach the discharge standards, and the present invention is an ideal purifying agent for industrial furnaces, industrial boilers and various fumes.
Description
The present invention relates to a kind of fume-clarifying agent for reducing smoke and dust and desulfurizing, belong to environmental protection and pollution control technical field, be specially adapted to the purification in Industrial Stoves, Industrial Boiler and various smoke pollutions source.
As everyone knows, flue gas is coal-fired flue-gas especially, is the primary pollution source of atmospheric environment.It comprises oxide contaminants such as smoke contamination, S, N.In order to control pollution, improve air quality, State Bureau of Environmental Protection is to the suspension SO in the fume emission
2And lingemann blackness carried out strict quantification requirement, yet because the shortage of fund and the backwardness of technology, many administration projects or owe to drag unsettled or blindly start and do not reach discharge standard, and therefore enterprise can't bear the heavy load.It mainly is the dustiness of flue gas that early stage atmosphere quality requires, and corresponding cleaner is to be the first generation dry dust removal technology of representative with cyclone dust collectors.Along with the deterioration of environment, the discharge standard of flue gas that country is strict, particularly 1998 begin SO
2Discharging strict requirement has been arranged, first generation dry dust removal technology obviously can not adapt to this requirement, and the emergence of second generation wet-scrubbing equipment has been arranged for this reason.Its appearance is significantly improved than first generation dry dust removal technology, but still can not satisfy the requirement of standard limit of smog release, mainly shows: the lingemann blackness that 1, can not guarantee to discharge flue gas effectively reliably is up to standard; 2, desulfuration efficiency is low.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art and a kind of lingemann blackness that can solve flue gas effectively is provided, make it qualified discharge, the fume-clarifying agent for reducing smoke and dust and desulfurizing of high-efficiency desulfurization.
The object of the present invention is achieved like this: it is made up of APES, sodium carbonate, anhydrous sodium sulfate, and the weight percent content of each component is: APES 42～47, sodium carbonate 45～50, anhydrous sodium sulfate 8～10.
The present invention has the following advantages compared to existing technology:
1, can solve the lingemann blackness of flue gas effectively, make it qualified discharge.The supporting use of XCT smoke dispersal, dust removal and desulphurization tower that the present invention and this are developed for smoke elimination, desulfurization, the clarifying smoke of the Industrial Stoves that built up, Industrial Boiler, can be brought into play catharsis to greatest extent.Lingemann blackness can be below 1 grade from 5 grades of purifications.
2, desulfurized effect is good, SO
2Removal efficiency is more than 80%.
3, the scope of application is extensive, is applicable to the purification treatment in Industrial Boiler, Industrial Stoves and various smoke pollutions source.And can be applicable in present other various types of wet method dedusting systems, only need the present invention is added in the recirculated water, can obtain desirable effect.
Below in conjunction with embodiment in detail the present invention is described in detail.
The present invention is made up of alkyl phenol polyvinylether, sodium carbonate, anhydrous sodium sulfate.The weight percent content of each component is represented with following table:
| The component title | Weight % | Weight % | Weight % | Weight % | Weight % | Weight % | Weight % | Weight % |
| Alkyl phenol polychlorostyrene ether | 42 | 44 | 45 | 46 | 47 | 47 | 48 | 49 |
| Sodium carbonate | 50 | 46 | 45 | 45 | 45 | 43 | 44 | 42 |
| Natrium carbonicum calcinatum | 8 | 10 | 10 | 9 | 8 | 10 | 8 | 9 |
Manufacture method of the present invention and step:
1, raw material is sieved respectively;
2, the raw material after will sieving is gone into refiner and is ground, and grinds to form-200 meshes;
3, the raw material of-200 meshes is used the meter computation weigh respectively by formula rate;
4, by formula rate three kinds of raw materials are mixed and incorporate batch mixer into and carry out mixing and stirring;
5, mixed raw material is gone into constant temperature increase-volume device, temperature is 60C °;
6, pulverous finished product packing is standby.
Using method of the present invention and characteristics:
The present invention is a kind of white powder, and nontoxic no stink is soluble in water.The long-term storage idol has caking, but does not influence result of use, should be placed on aeration-drying place.Can directly it be rendered in the circulatory pool during use, stirring is promptly quickly dissolving slightly, and the effect of bringing into normal play.
