Abstract
The invention discloses a method and a device for igniting coal gas discharged from a heat storage chamber and a flue to a chimney when a cross flame kiln and a horse shoe flame kiln are reversed in the industry of water-glass and glass, which belong to the technical field of coal gas burning, in particular to the technical field of burning the coal gas discharged from the heat storage chamber andthe flue to the chimney when the cross flame kiln and the horse shoe flame kiln are reversed in the industry of water-glass and glass. The method comprises the following steps that: an ignition device is arranged on a place more than 0.5 meter away from a middle flue inlet of a coal gas exchanger and on the furthest place at the root of the chimney; the air enters the flue from an air vent; afterthe coal gas exchanger starts reversing and before the coal gas reaches the ignition device, the ignition device is started or ignited; and the coal gas is mixed and burnt with the air from the air vent. The ignition device must provide sufficient ignition energy and generally uses flammable objects, flammable gases or high-voltage sparks.
Description
Technical field
The invention belongs to the gas-fired technical field, especially be discharged to the gas-fired technical field of chimney during the commutation of the cross flame kiln of waterglass, glass industry, horse shoe flame kiln in regenerator, the flue.
Background technology
Be discharged to the coal gas of chimney when the cross flame kiln of traditional waterglass, glass industry, the commutation of horse shoe flame kiln in regenerator, the flue, generally do not process, directly be discharged in the atmosphere, coal gas contacts with air and blasts easily during misoperation, the coal gas blackness that is discharged to atmosphere is defective, carbon monoxide in the coal gas and fuel gas are diffused into the surrounding area and catch fire easily, poison, and are the focal issues that each department environmental administration supervises enterprise's rectification.Part producer improves, and this part coal gas is recycled by air-introduced machine, and first Safety water seal is installed in perforate on the side flue of coal gas, air-introduced machine, and second Safety water seal is introduced the opposite side flue, enters the kiln burning again.Perhaps first Safety water seal is installed in perforate on the side flue, air-introduced machine, and second Safety water seal is guided to the outside and is burnt in vain.Handle coal gas by air-introduced machine, exist investment big, complicated operation is sneaked into problems such as coal gas sets off an explosion with air easily.
Summary of the invention
At the deficiencies in the prior art, be discharged to the ignition method and the device thereof of the coal gas of chimney when the purpose of this invention is to provide cross flame kiln, the horse shoe flame kiln commutation of a kind of waterglass, glass industry in regenerator, the flue, it can be lighted flue in the middle of entering and the coal gas that finally be discharged to chimney and make it completing combustion, contact and blast when having avoided misoperation with from the air after the commutation of air commutator, shortened the blanking time that coal gas commutator and air commutator carry out switch operation.After the gas-fired, chimney breast row is a flue gas to atmosphere, not only solved the pollution that the underproof coal gas of blackness causes to atmosphere from chimney breast row, and eliminated that carbon monoxide in the coal gas and fuel gas be diffused into that the surrounding area may cause catch fire the influence of poisoning.And invest little, simple to operate, secure safely.
The object of the present invention is achieved like this: the ignition method that is discharged to the coal gas of chimney during the commutation of the cross flame kiln of described waterglass, glass industry, horse shoe flame kiln in regenerator, the flue: igniter is arranged on apart from the place of middle chimney intake distance more than 0.5 meter of coal gas exchanger as far as the place of chimney root.Air enters flue from air vent.After coal gas exchanger begins commutation, coal gas trunk line, flue in the middle of the coal gas of the side coal gas flue of getting angry before this commutation enters.Before coal gas arrives igniter, start or light igniter.Coal gas arrives the igniter place, mixes with air from air vent and burns.
The igniter that is used for coal gas ignition is generally used combustible object such as firewood, cotton yarn.Fuel gas such as natural gas, acetylene gas etc.High-voltage spark.Enough ignition energies must be provided, stretch in the flue, contact, coal gas is lighted with coal gas.
Gas igniter commonly used: the coal gas of using trunk line is as fuel gas, the diameter of kindling material pipeline is greater than 10 millimeters, one end communicates with the coal gas trunk line, the middle by-pass valve control of installing, the other end inserts flue in air vent, expose the flue interior walls more than 5 millimeters, the gas flow that uses must can provide enough ignition energies, stretch in the flue, contact, coal gas is lighted with coal gas.
The ignition method of igniter is as follows:
A. open the lid of air vent, owing to be negative pressure in the flue, air self-ventilation hole enters flue.
B. the torch self-ventilation mouth with the firewood lighted or natural gas, acetylene gas stretches in the flue, keeps the torch burning not interrupt.1-2 is after second, and coal gas exchanger begins commutation, and flue in the middle of coal gas enters arrives the igniter place, mixes with air from air vent and burns.Keep the torch burning, fall up to the coal gas completing combustion that enters flue.
C. extinguish torch, the self-ventilation mouth is taken out, and the air vent lid of flue is covered and seals tightly.The ignition method of igniter commonly used is as follows:
A. open the lid of air vent, owing to be negative pressure in the flue, air self-ventilation hole enters flue.
B. firewood or the high-voltage spark of lighting reached kindling material pipe outlet in the flue, keep torch burning or high-voltage spark not to interrupt.1-2 is after second, and the by-pass valve control of the kindling material pipeline that will be connected with trunk line is opened, and the coal gas of kindling material pipe outlet takes fire, and the self-ventilation mouth is taken out torch, extinguishes torch, or closes the high energy electric spark.
C. the gas-fired that keeps the kindling material pipe outlet, coal gas exchanger begin commutation, and flue in the middle of coal gas enters arrives the igniter place, mix with air from air vent and burn.Keep the gas-fired of kindling material pipe outlet, fall up to the coal gas completing combustion that enters flue.
D. the by-pass valve control of the kindling material pipeline that will be connected with trunk line is closed, and the air vent lid of flue is covered and seals tightly.
For guaranteeing the success and the safety of igniting, the air capacity that air vent enters during igniting, minimum should make combustible, gas fuel burning that enough air capacities are arranged, and burning is not interrupted; The gaseous mixture physical efficiency that the coal gas of flue forms in the middle of entering after should making it mix the back and commutate is lighted by igniter.Maximum should make the combustible of burning, fuel gas not blown out by air; The combustion of mixed gas speed that the coal gas of flue forms in the middle of entering after should making it mix the back and commutate is less than the flowing velocity of coal gas in the flue or mist.
Use the ignition operation of high-energy igniter to control by computer controller.
