Definitions
- the present invention relates to a combustion type waste gas treatment method and apparatus for treating waste gas discharged from processes for manufacturing industrial products such as semiconductors and liquid crystals, for example, a hazardous and combustible or hardly decomposable waste gas containing silane gas (SiH 4 ) or a halogen-containing gas (NF 3 , ClF 3 , SF 6 , CHF 3 , C 2 F 6 , CF 4 , etc.), by combustion or thermal decomposition and/or oxidative decomposition.
- silane gas SiH 4
- a halogen-containing gas NF 3 , ClF 3 , SF 6 , CHF 3 , C 2 F 6 , CF 4 , etc.
- a conventional combustion type waste gas treatment apparatus has a burner part and a combustion chamber provided, for example, at the downstream side of the burner part.
- a combustible gas (auxiliary burning gas) is supplied into the burner part and burned to form flames, and waste gas is burned with the flames.
- the combustible gas hydrogen gas, city gas, propane gas or the like is used as fuel gas, and oxygen or air is usually used as an oxidizing agent.
- Hydrogen gas has ignitionability and explosiveness. However, once hydrogen gas has started to burn, there is substantially no possibility that blow-off of flames may occur. Consequently, extremely stable combustion is obtained. Thus, hydrogen gas is suitable for use as fuel gas for combustion in the combustion type waste gas treatment apparatus. However, the use of hydrogen gas has the disadvantage that the cost is high and hence the running cost is unfavorably high. In addition, the longer the length of piping for supplying hydrogen gas from a storage container to the waste gas treatment apparatus, the more likely that the gas may leak from a joint portion of the piping.
- the ignition of combustion flames is confirmed by a combustion flame ignition confirmation method wherein the combustion flames are detected by using a UV (ultraviolet) sensor.
- a UV sensor ultraviolet
- the method of detecting the combustion flames by using a UV sensor involves the problem that a by-product, e.g. dust, generated during the waste gas treatment may undesirably close the light-collecting aperture.
- the method of detecting the combustion flames by using a UV sensor also has the following problem. In a case where reflected light of flames from the inner wall of the combustion part is to be detected, if a by-product having UV absorbing characteristics adheres to the inner wall of the reaction part, UV light is absorbed. Therefore, flames cannot be detected. There is also a problem that because of the high temperature of the reaction part, the light-collecting aperture may be heated to a high temperature and undesirably closed by melting or corrosion.
- the supply of auxiliary burning gas to the burner part is carried out through a nozzle hole opening on the inner wall surface of the burner part, and flames are formed by burning of the auxiliary burning gas blown off from the nozzle hole.
- the flames may blow off when the amount of waste gas introduced into the burner part fluctuates.
- backfire may occur in the fuel piping for supplying the auxiliary burning gas or elsewhere.
- the present invention has been made in view of the above-described circumstances to provide an apparatus capable of making waste gas harmless without unnecessary stay of a combustible substance in the system and without the need of a complicated piping arrangement and unlikely to cause a gas leakage accident. That is, it is an object of the present invention to provide a combustion type waste gas treatment method and apparatus using a mixed gas of hydrogen gas and oxygen gas as fuel gas for combustion to reduce the installation cost and the running cost and capable of substantially eliminating the leakage of hydrogen gas and oxygen gas.
- a first invention provides a combustion type waste gas treatment method in which waste gas is introduced into combustion flames to thermally or oxidatively decompose a combustible component in the waste gas.
- hydrogen gas and oxygen gas are generated by electrolysis of water and supplied as a gas for combustion to form the combustion flames.
- the hydrogen gas and the oxygen gas are preferably supplied to form the combustion flames as a mixed gas without changing the ratio of the gases as generated.
- a second invention provides a combustion type waste gas treatment apparatus having a burner part for forming combustion flames from hydrogen gas and oxygen gas, and a device for electrolysis of water to generate hydrogen gas and oxygen gas.
- a combustion chamber is preferably provided downstream of the burner part. In the combustion chamber, waste gas to be treated is introduced into the combustion flames to carry out thermal oxidative decomposition of the waste gas.
- a third invention provides a combustion type waste gas treatment apparatus having a burner part and a combustion chamber at the downstream side of the burner part.
- the burner part is supplied with an auxiliary burning gas to form combustion flames extending from the burner part toward the combustion chamber. Waste gas is introduced into the combustion flames to oxidatively decompose the waste gas.
- a pipe or a hole through which the combustion flames can be viewed directly is formed in a wall of the burner part upstream of the combustion flames.
- a UV sensor is provided to detect the combustion flames through the pipe or the hole.
- the combustion type waste gas treatment apparatus is free from the problem that a by-product, e.g. dust, generated during waste gas treatment, closes the light-collecting aperture to thereby disable the UV sensor from detecting the combustion flames. Further, because the combustion flames are viewed directly through the pipe or the hole, even if a by-product having UV absorbing characteristics adheres to the inside of the reaction part, it will not obstruct the collection of light and will not interfere with the UV sensor detecting the combustion flames. Because the pipe or hole allowing direct viewing of the combustion flames is provided in a side wall of the burner part upstream of the combustion flames, at which the temperature is relatively low, there is no likelihood of the light-collecting aperture being closed by melting or corrosion due to high temperature.
- a by-product e.g. dust
- a UV light-transmitting member is disposed at the joint between the pipe or hole allowing direct viewing of the combustion flames and the UV sensor to isolate the UV sensor from the atmosphere in the burner part, and a purge gas is supplied from the UV light-transmitting member in the pipe or the hole toward the burner part.
- the pipe or hole allowing direct viewing of the combustion flames is closed at an end thereof remote from the burner part, and light from combustion flames in the pipe or the hole is transmitted to the UV sensor through an optical fiber.
- the UV sensor can be installed where there is no problem in terms of the space, heat resistance, etc. when the UV sensor cannot be installed at the end of the pipe or the hole remote from the burner part owing to the problems of the space, heat resistance, etc.
- a fourth invention provides a combustion type waste gas treatment apparatus having a burner part and a combustion chamber at the downstream side of the burner part.
- the burner part is supplied with an auxiliary burning gas to form combustion flames extending from the burner part toward the combustion chamber. Waste gas is introduced into the combustion flames to oxidatively decompose the waste gas.
- the supply of the auxiliary burning gas to the burner part is carried out through a nozzle hole that opens on the inner wall surface of the burner part.
- the nozzle hole comprises a group of at least three nozzle openings formed close to each other.
- the nozzle hole comprises a group of at least three nozzle openings, it is possible to prevent blow-off of the combustion flames or other similar problem even if there are fluctuations in the amount of waste gas introduced into the burner part.
- the nozzle hole is formed from a group of at least six nozzle openings, whereby it is possible to prevent blow-off of the combustion flames or other similar problem even if the amount of waste gas introduced fluctuates.
- the injection velocity of the auxiliary burning gas injected from the group of nozzle openings is preferably set higher than the propagation velocity of the flames.
- the flame propagation velocity is determined by the kind of fuel gas used as the auxiliary burning gas, the mixing ratio of air or oxygen to be premixed, the configuration and arrangement of the nozzle openings, etc.
- the auxiliary burning gas injection velocity is determined by the supply pressure of the auxiliary burning gas and the total sectional area of the nozzle openings. Therefore, by taking into consideration these factors, the total sectional area of the nozzle openings or the like is set so that the auxiliary burning gas injection velocity is higher than the flame propagation velocity.
- an H 2 /O 2 generator having a device for electrolysis of water is provided to generate hydrogen gas and oxygen gas by electrolysis of water using the H 2 /O 2 generator, and a mixed gas of hydrogen and oxygen gases generated is supplied to the burner part. Therefore, it is unnecessary to supply an oxidizing agent gas from the outside. If the H 2 /O 2 generator is disposed as close to the burner part as possible and the burner part is supplied with a mixed gas of hydrogen and oxygen in the ratio of the gases as generated, the length of piping required can be minimized. In addition, because it is unnecessary to supply the hydrogen gas and the oxygen gas through respective lines, the piping arrangement is simplified, and the pipe laying cost is reduced.
- the arrangement may, of course, be such that two different kinds of gas are supplied to the burner part through separate lines to perform mixed combustion by using a burner having a double nozzle structure or the like.
- the length of piping is short, the possibility of leakage of hydrogen and oxygen gases reduces. The possibility of ignition occurring in such short piping is weak. It is, needless to say, necessary to pay attention to backfire from the nozzle from the structural or operational point of view when the present invention is carried out. Further, because water is electrolyzed to obtain fuel on the spot, no excess combustible gas will stay in the system. In an emergency, it is possible to cope with the situation by stopping the operation of the H 2 /O 2 generator. Therefore, the present invention is safe, and the running cost is reduced.

- Reference numeral 1 denotes an H 2 /O 2 generator for generating hydrogen gas and oxygen gas by electrolysis of water.
- Reference numeral 2 denotes a waste gas treatment apparatus 2 for treating hazardous and combustible waste gas G 1 from a semiconductor manufacturing system by thermal oxidative decomposition.
- a mixed gas (H 2 +(1 ⁇ 2)O 2 ) of hydrogen and oxygen from the H 2 /O 2 generator 1 is supplied to a burner part (detailed later) of the waste gas treatment apparatus 2 through piping 3 .
- the mixed gas of hydrogen and oxygen burns to form flames toward a combustion chamber.
- the waste gas G 1 from a waste gas inlet pipe 4 is introduced into the flames to thermally and oxidatively decompose the waste gas G 1 to make it harmless.
- the treated waste gas is discharged through an exhaust pipe 5 .
- As the H 2 /O 2 generator 1 an existing one can be used.
- the length of the piping 3 can be minimized by disposing the H 2 /O 2 generator 1 in the vicinity of the burner part. Supplying a mixed gas of hydrogen and oxygen dispenses with supplying hydrogen gas and oxygen gas through separate lines. Therefore, the piping arrangement is simplified, and the amount of gas staying in the system reduces by an amount corresponding to the reduction in length of the piping 3 . It is also possible to eliminate gas leakage accidents. Consequently, safety improves.
- the H 2 /O 2 generator 1 and a combustion chamber 20 having a burner part 10 are provided close to each other. Therefore, the H 2 /O 2 generator 1 and the combustion chamber 20 can be packaged into a single housing 100 . At this time, it is desirable that the housing 100 should be provided with an exhaust duct 101 . By doing so, when there is a leakage in the piping, safety can be ensured even more reliably. Installation in a plant becomes easier than in a case where hydrogen gas and oxygen gas are separate from each other. The exhaust gas passing through the exhaust duct 101 is released into the atmosphere through a water scrubber in the plant.

Therefore, it is possible to prevent blow-off of the combustion flames or other similar problem even if there are fluctuations in the amount of waste gas introduced into the burner part. Further, it is possible to prevent backfire from spreading into the auxiliary burning gas supply piping by setting the injection velocity of the auxiliary burning gas injected from the nozzle openings higher than the flame propagation velocity.
