Abstract
The utility model discloses a calcium carbide furnace straight-exhaust flue gas treatment device which structurally includes that another gas duct is formed on the upper portion of a calcium carbide furnace straight-exhaust gas duct, a water cooling butterfly valve is installed on an inlet of the gas duct, an automatic ignition device and a dust collection cover are sequentially installed above the gas duct, and the dust collection cover is sequentially connected with an electric butterfly valve, a settler and a bag-type dust remover in pipeline mode. According to the calcium carbide furnace straight-exhaust flue gas treatment device, high-concentration carbon monoxide (CO) is safely conveyed into a dust removing system, and explosive risks caused by the high-concentration CO are avoided. The automatic ignition device and the dust collection cover are installed on an outlet of the straight-exhaust gas duct, high-concentration furnace gas (with the CO as a main ingredient) is ignited at an opening of the gas duct, and then the high-concentration furnace gas is conveyed into the dust removing system through the dust collection cover and a pipeline, the furnace gas and dust are treated through the dust removing system and are exhausted to the air after reaching standards, and the purpose of zero release in calcium carbide production is achieved.
Description
Technical field
The utility model relates to a kind of flue gas processing device, refers in particular to the in line flue gas processing device of closed calcium carbide furnace.
Background technology
At present, during the chemical industry furnace of calcium carbide was produced, underrun and furnace of calcium carbide moved the furnace gas that produces when undesired and process and become the problems of concern of environmental administration.Closed calcium carbide furnace has two flues, pure qi (oxygen) flue and thick gas flue.During the furnace of calcium carbide normal operation, furnace gas (CaO+3C=CaC
2+ CO, CO concentration in flue gas is more than 70%) entering purification dust removal system from the pure qi (oxygen) flue, the furnace gas after the purification uses calcined limestone or supplies with the user, reaches the target of recycling economy; Furnace of calcium carbide move when undesired (as furnace of calcium carbide underrun, furnace of calcium carbide collapse greatly material, roasting electrode, to process charge level, maintenance cleaning system equipment, furnace pressure high), must open thick gas flue, furnace gas is discharged in the air, this severe contamination environment.Present domestic calcium carbide industry can't effectively be processed the in line smoke problem of furnace of calcium carbide.
For the closed calcium carbide furnace flue gas, CO composition large (CO belongs to inflammable explosive article) in the flue gas, calcium carbide stove exhaust purification dust removal system have been introduced and the equipment and the technology that have domesticized have reached in the world top standard.
One cover purification dust removal system is arranged on the closed calcium carbide furnace purification flue at present, produce the furnace gas emission problem that produces when undesired if a cover purification dust removal system is installed again then can be solved above-mentioned furnace of calcium carbide on thick gas flue.
The utility model content
The technical problems to be solved in the utility model provides the in line flue gas processing device of a kind of furnace of calcium carbide; this treating apparatus has reduced the pernicious gas of generation in the closed calcium carbide furnace production to the pollution of environment; can stop pernicious gas to the harm of personal injury and production equipment, be a kind of isolated plant that meets national energy-saving reduction of discharging, protection of the environment policy.This device solves the in line flue furnace gas of closed calcium carbide furnace (CO concentration 10%～80%) enter the difficult problem that the danger of blasting after the dust pelletizing system and furnace gas temperature (500 ℃～1000 ℃) burn out dust-collecting bag.
The technical problems to be solved in the utility model is realized by following scheme: the in line flue gas processing device of furnace of calcium carbide, it is characterized in that: open in addition a flue on the in line flue of furnace of calcium carbide top, the water-cooled butterfly valve is installed by the import department of described flue, the flue top is installed automatic ignition device, dust shield successively, and dust shield is connected with electric butterfly valve, settler, sack cleaner pipeline successively.
The utility model also comprises following scheme: the upper and lower that the in line flue of described furnace of calcium carbide is opened floss hole in addition fills respectively water-cooled control valve and gas analyzer.
Operation principle of the present utility model: the key equipment of the in line flue gas processing device of furnace of calcium carbide is dust shield and automatic ignition device.
1, the effect of dust shield: air and furnace gas mist are collected in the deduster and are processed, and its Air has played CO concentration and the temperature that reduces in the furnace gas, the explosion danger when having avoided furnace gas to enter dust pelletizing system.
2, the effect of automatic ignition device: automatic ignition device and water-cooled butterfly valve and gas analyzer design interlocking.As long as the CO concentration that the water-cooled butterfly valve is opened or gas analyzer analyzes reaches explosion limit, automatic ignition device just begins sparking, and the CO burning is gone out at floss hole, has avoided the high CO of concentration to enter the danger that sets off an explosion in the dust pelletizing system.
3, water-cooled butterfly valve, automatic ignition device and electric butterfly valve are set to automatic control, and operating sequence should arrange according to the operating sequence of house coal gas hood and lampblack absorber, thereby has eliminated potential safety hazard.
4, the effect of settler: reduce furnace gas temperature and sedimentation bulky grain dust.
5, the CO concentration in the furnace gas is 30% when following, because the CO concentration that enters of air in the dust shield is reduced to below 10%, just can not process in line flue furnace gas emission problem so do not start automatic ignition device, and security incident avoided in assurance.
When 6, the CO concentration in the furnace gas 30% is above, start automatic ignition device the CO burning at floss hole, avoid the high concentration furnace gas to enter the danger that dust pelletizing system sets off an explosion.
Advantage of the present utility model: the dust shield that the in line flue gas processing device of this furnace of calcium carbide is installed can be connected to workshop existing stokehold dedusting or other dust pelletizing system by pipeline and sack cleaner, the in line flue gas of furnace of calcium carbide and air enter simultaneously that CO concentration and temperature reduce in a large number behind in line flue top and dust shield and the sack cleaner, the difficult problem that the danger of having avoided the in line flue furnace gas of closed calcium carbide furnace (CO concentration 10%～80%) to enter blasting after the dust pelletizing system and furnace gas temperature (500 ℃～1000 ℃) burn out sack cleaner.
This device sucks in line flue gas in the sack cleaner by dust shield, igniter, pipeline, settler, and the flue gas after purifying by sack cleaner is put into atmosphere, can realize closed calcium carbide furnace production zero-emission, reaches the purpose of environmental protection.
