Description
Technical field: the utility model relates to a kind of gas cleaning plant, is meant a kind of coal tar smoke eliminator especially.
Background technology: coal tar enamel is a kind of of anticorrosive paint, because its unique antiseptic property, so it has irreplaceable status in burying ground or submarine pipeline anticorrosion, but coal tar enamel all can produce the filemot sharp aroma flue gas that has in the whole process of fusing and coating, the Main Ingredients and Appearance of this flue gas is carbolineum in the coal tar enamel and the volatile substance in the coal dust, these materials are water insoluble, generally dissolve in dimethylbenzene, the washing oil equal solvent; If not treated just direct emptying meeting causes bigger pollution to environment to this flue gas; At present, domestic having with the washing oil is the smoke eliminator of absorbing medium, and the oxious component that it can absorb in the coal tar enamel flue gas well reaches antipollution purpose; But, because washing oil is to absorb oxious component in the coal tar enamel flue gas by dissolution, so increase along with dissolved matter concentration in the washing oil, the absorption dissolution of washing oil will be worse and worse, necessary regular all or part of replacing washing oil during use, so just brought two problems: the one, the price height of washing oil, cause the operating cost height, the 2nd, the regeneration technology complexity of scrapping washing oil, the processing of can't regenerating at the use scene, can only transport the coke-oven plant back and process, this has just further improved operating cost.
The utility model content: the purpose of this utility model provides a kind of water as the low coal tar smoke eliminator of operating cost that adheres to medium.
The purpose of this utility model is to realize like this, a kind of coal tar smoke eliminator, comprise air exhauster and the blow-down pipe that links together with the air outlet of air exhauster, it also includes gas cleaning plant and the water decontamination cycle device that links together by pipe each other;
Wherein gas cleaning plant is by smoke-intake pipe, spray tower, intervalve, mist collecting column, tube connector and the adsorption tower of series connection constitute successively mutually;
Water decontamination cycle device is to be made of the oil water separator that is cascaded successively mutually by pipe, sewage header tank, sewage water pump, plate and frame filter press, water purification header tank and water purification water pump; Wherein the water inlet of oil water separator links together by pipe and the sewage draining exit that is positioned at spray tower and mist collecting column bottom; The delivery port of water purification water pump links together with an end of spray tower water supply valve and mist collecting column water supply valve respectively by pipe;
Be provided with fog-spray nozzle in spray tower, fog-spray nozzle links together by the other end of pipe and spray tower water supply valve, and the outlet of smoke-intake pipe is arranged on the top of spray tower, is provided with the intervalve as exhanst gas outlet in the bottom of spray tower; The other end of intervalve and the bottom of mist collecting column link together;
Above intervalve enters the mouth in mist collecting column, set gradually abacus, filler support deflection plate, fiberfill layer and grate net from bottom to top, wherein on the tower wall of mist collecting column above the orifice plate, be provided with water filling port, water filling port links together by the other end of pipe and mist collecting column water supply valve, the exhanst gas outlet of mist collecting column is arranged on the top of mist collecting column, and links together with an end of tube connector;
The other end of tube connector and the top of adsorption tower link together, and are fixed with active carbon layer by up and down two-layer active carbon location orifice plate in adsorption tower; The exhanst gas outlet of adsorption tower is positioned at the bottom of adsorption tower, and the air inlet of itself and air exhauster links together.
Because the main adhesion medium in the utility model is a water cheap and easy to get, it is to remove oxious component in the coal tar enamel flue gas by adhesive attraction, and water itself and these oxious components and immiscible, so oil and slag in the flue gas under the scene of using just can adhere to water by oil water separator and plate and frame filter press are separated, it is recycling to make that used water can access, and greatly reduces operating cost; And be effective ingredient in the coal tar enamel basically by the oil that the utility model is separated from water, the raw material that can be used as coal tar enamel reuses, and the solid slag of separating can be used as the combustion adjuvant use of colm, so it can further reduce operating cost; Learn through actual measurement, the utility model accumulative total on steel pipe coating coal tar enamel production line is moved 72 hours, total inventory of coal tar enamel is 60 tons, isolate 75 kilograms in waste oil, 150 kilograms in wet waste residue through the utility model from flue gas, the tail gas medium pitch smoke density measured value after the processing is 5mg/m
3, reached the discharge standard 50mg/m of national GB9078-1996 standard code
