Operation principle of the present utility model is summarized as follows:
The air mixture that contains impurity is sent into water seal 8 through roots blower, and (water seal 8, drier 12, filter 15, an aflter-fillter 17 are tank structure, jar is high to be 2 meters, diameter is 1 meter, air accumulator 19 is decided on production and use scale), about 60 centimetres deeply on the lime white layer of depositing in the middle of the water seal 89, appendix inserts in the lime white layer 9 about 30 centimetres, in this way that gas is central with carrying out cooling processing in water seal 8, reduce the temperature of gas, the character that utilization is expanded with heat and contract with cold increases gas density, reduces the potential danger that causes because of when gases are heated, they expand; Simultaneously because the white lime in the lime white is that calcium hydroxide is slightly soluble in water, be dissolved in the water calcium hydroxide can with the carbon dioxide generation chemical reaction in the gas, generate calcium carbonate, calcium carbonate is water insoluble, therefore other not water-soluble white lime can constantly continue to be dissolved in the water in the lime white, continue and carbon dioxide generation chemical reaction, remove the carbon dioxide in the gas in this way, to eliminate the inhibitory action of carbon dioxide to gas combustion, make full combustion of gas, the performance more heat is promoted combustion efficiency, avoids remaining pernicious gas to pollute in the middle of entering atmosphere simultaneously; In addition since cooling make in the gas with tar partly deposit, improve the purity of gas.
In order to make gas keep enough density and pressure, the gas after the output of water seal 8 tops enters drier 12 by drier 12 bottoms again, because gas cools off through lime white in water seal 8 and removes after the processing of carbon dioxide, temperature reduction, density and purity increase, but because the original temperature of gas is higher, process from lime white makes the part water vapor, take a large amount of steam out of, water content also increases thereupon, causes humidity to increase, and also influences its use, therefore, need through processed.Gas enters when is accumulating drier 12 backs and utilizes lump lime to carry out the drying processing, utilize the water imbibition of quick lime, absorb the moisture of taking out of in the lime white of gas from water seal, gas is kept dry, be beneficial to igniting and burning, export by the top again when waiting to accumulate certain density and pressure.
The deflector 10 and the pressure guide plate 14 that are provided with at the middle and upper levels of water seal 8 and drier 12 inside, all be to tilt to the top, center, but effect is different: the deflector 10 in the water seal 8 is in order to make the steam and the tar that condense flow back to the bottom along water seal 8 inwalls, tar is deposited on water seal 8 inwalls, play diaphragm, reduce or avoid the corrosion of lime white, increase the service life the water seal inwall; Pressure guide plate 14 in the drier 12 is in order to reduce the top area, thereby increases the pressure of gas, and gas is exported smoothly, and gas is fully contacted with quick lime when accumulating as far as possible, and steam as much as possible is absorbed by quick lime, reaches abundant drying.
After the gas drying device 12 tops output, enter filter 14 bottoms No. one time, gas utilizes the adsorptivity characteristics of two organic filter courses in the filter 15, contained tar in the adsorbed gas.Through after the filtration of two-layer organic matter, most of tar is adsorbed, and has played the effect of decoking, to reduce the tar smell that gas in use occurs and the influence of dirt.After filtering through a filter 15, gas, enters by aflter-fillter 17 bottoms through top output.
After gas enters aflter-fillter 17, utilize inorganic matter filter course 17 further drying, purified treatment.This process is to utilize the water imbibition and the adsorptivity of coke and quick lime, and gas is carried out further dry the processing, with last small portion of residual tar absorption, improves gas purity simultaneously.
Why the utility model adopts said structure and material to the filtration treatment of gas, and its unique reason is arranged.Adopt organic filter course 16 preceding, inorganic matter filter course 18 after structure, be because organic filter course 16 might make moist, thereby cause being with steam once more after the gas drying device processed, the final combustion efficiency that influences, in order to prevent the appearance of this phenomenon, adopt organic filter course 16 preceding, inorganic matter filter course 18 after structure, even organic filter course 16 makes moist, still can tar adsorption, can be when being mixed in the steam process aflter-fillter 17 in the gas by quick lime filter course absorption wherein, also just can ensure the drying of gas, ensure combustion efficiency.
At last, gas exports air accumulator 19 to by aflter-fillter 17 tops, and adsorption cleaning layer 20 effect in the air accumulator 19 are finally gas to be carried out comprehensive purified treatment.Because air accumulator 19 volumes are generally very big, want 1 ten thousand stere at least, can't use support to fix, its bottom directly can only be contacted with ground, for anti-oxidation, iron plate is not adopted in the bottom, but adopts the cement face.Adopt such structure, the cement face may make moist owing to surrounding environment is moist, causes gas to make moist once more in the process that stores, and therefore needs to use quick lime that gas is proceeded dry the processing.Simultaneously owing to still may have tar and peculiar smell in the gas, therefore utilize the suction-operated of charcoal and bamboo charcoal, tar adsorption and peculiar smell prevent from tangible peculiar smell in use to occur and influence result of use.Carrying out final purification in addition and handle in air accumulator 19, also is to consider that gas flowing velocity this moment is slow, is beneficial to purified treatment.Gas is through after storage and the final purification processing, again by 21 supply associated user or the generatings of clean gas conveyance conduit.
