The present invention relates to a waste gas combustion burner and a gas scrubber using the same, and more particularly, to a waste gas combustion burner and a gas scrubber using the same for burning and treating toxic waste gas discharged after being used in a semiconductor manufacturing process and a chemical process. It is about.

In general, waste gases emitted from semiconductor manufacturing processes or chemical processes, in particular, PFC (Perfluorocompound) gases such as C2F4, CF4, C3F8, NF3, SF6, are not only harmful to the human body because they are toxic, explosive, and corrosive, and are also purified. If it is not immediately discharged to the air there was a problem causing serious environmental pollution.

Accordingly, the waste gas must be discharged to the atmosphere through a detoxification process that lowers the content of harmful components below the allowable concentration.

Various gas scrubbers such as a combustion method, a wet method, an adsorption method, a cooling method, and a catalyst method are generally used for the detoxification treatment of the waste gas.

Among them, the combustion method is a treatment method in which waste gas is harmless with a combustor of a heater and an ignition system.

As an example of the ignition type burner in the combustion method, Korean Patent Laid-Open Publication No. 2004-32262 shows an example of a burner body having a plurality of combustion zones having a multi-stage combustion zone extending stepwise toward a combustion chamber, It comprises a carburettor provided to supply a mixed gas of fuel gas and air to the combustion zone, and an ignition means provided to ignite the mixed gas supplied to the uppermost combustion zone.

Conventional combustion burners supply the reaction air to the combustion zone at the most upstream through the air introduction ports, and mix the fuel gas and air to supply the combustion zone downstream to the waste gas introduction ports, but the waste gas flows in the direction of flame flow. As a result, there is a problem in that flame stability is lowered by intensively supplying only to the center of the flame zone, causing flameout.

In addition, since the mixing of fuel gas, air, and waste gas is not made smoothly, the combustion characteristics such as self-ignition, flame propagation, etc. of the fuel gas are reduced, and thus the combustion temperature is difficult to rise. Due to the incomplete combustion of the waste gas there was a problem that the treatment efficiency is extremely reduced.

Although not separately shown in the drawings, the gas inlet 13 is connected to the gas supply device, and the catalyst inlet 14 is connected to the catalyst supply device.

In addition, the gas supply device includes, for example, a cylinder for storing combustion gas and various valves mounted at a pipeline connected to a gas inlet so as to control the flow, flow rate, and pressure of the combustion gas supplied from the bomb. It can consist of a device and a gauge.

The catalyst supply device includes an air compressor that generates compressed air, an air dryer that removes impurities such as moisture contained in the compressed air supplied from the air compressor, and a gas to remove the flow, flow rate, and pressure of the compressed air. It can be composed of various valve devices and gauges mounted on the pipeline connected to the inlet.

As described above, the second flow path 16 and the third flow path 17 each form an acute angle toward the first flow path 15 side, so that the waste gas combustion gas and the catalyst inlet flowing from the gas inlet 13 are inclined. As the injection speed of the catalyst flowing from the 14 increases at the point A at which the acute angle is formed in the second flow path 16 and the third flow path 17, the waste gas combustion gas at the waste gas outlet 12 and The catalyst can be mixed more smoothly with the waste gas.

If the waste gas combustion gas and the catalyst at the waste gas outlet 12 are mixed smoothly with the waste gas, the waste gas is not only intensively supplied to the center of the flame zone along the flow direction of the flame, but also blowout. It does not generate a fire, and has the advantage of increasing flame stability.

In addition, since the mixing of the waste gas combustion gas, the catalyst, and the waste gas is performed smoothly as described above, the combustion characteristics such as self-ignition and flame propagation of the waste gas combustion gas are increased. It is easy to increase the combustion temperature, thereby suppressing incomplete combustion of the waste gas has the advantage of extremely increasing the treatment efficiency.

In the third to fifth injection nozzles 32, 33, and 34, sodium hydroxide is injected to cool the combustion gas again. However, sodium hydroxide may be replaced with other cooling liquids and gases.

However, if necessary, the second to fifth spray nozzles 31, 32, 33, and 34 may all be designed to spray water.

The operation of the burner for waste gas combustion according to the present invention is as shown in FIGS. 1 to 4.

First, the toxic waste gas flows into the waste gas inlet 11 of the nozzle unit 10, and the waste gas flows out of the waste gas outlet 12 along the first flow path 15.

At this time, the waste gas flowing out to the waste gas outlet 12 is the waste gas combustion gas flowing out to the waste gas outlet 12 along the second flow path 16 through the gas inlet 13, and through the catalyst inlet 14 The mixture is discharged while being mixed with the catalyst flowing out of the waste gas outlet 12 along the three flow paths 17.

5 to 7, the gas scrubber 100 using the waste gas combustion burner 1 according to the present invention includes a cooling chamber 110 and a storage tank 120.

The waste gas combustion burner 1, the cooling chamber 110, and the storage tank 120 is preferably provided in the case 102 forming the outline of the present invention.

First, since the burner 1 for waste gas combustion has the same structure as described in the above embodiment, detailed description of the structure is omitted here.

The burner 1 is preferably directly connected to the waste gas supply pipe 101 to receive the waste gas from the waste gas supply source (not shown) to the waste gas inlet 11 of the nozzle unit 10.

On the other hand, the cooling chamber 110 is provided in parallel with the burner 1 receives the combustion gas cooled from the cooling washing unit 30 of the burner 1 to cool again.

In an embodiment, the cooling chamber 110 has a pipe shape, and the cooling chamber 110 is deflected a number of times to increase the time for which the combustion gas stays therein.

In an embodiment, the cooling chamber 110 has a shape bent in a '∩' shape, but may have a shape in which the '∩' and '∪' form continuously connected as necessary.

As such, when the cooling chamber 110 has a curved shape to increase the internal residence time of the combustion gas, the contact time between the cooling medium and the combustion gas injected from the injection nozzles 111, 112, and 113 described below becomes long, thereby improving cooling efficiency. It has the advantage of being extremely high.

The cooling chamber 110 has at least one injection nozzle (111, 112, 113) for injecting a cooling medium therein.

The injection nozzles 111, 112, and 113 of the cooling chamber 110 are sequentially arranged with the sixth to eighth injection nozzles 111, 112, and 113 along the advancing direction of the combustion gas, and the injection nozzles 111, 112, and 113 are the cooling cleaners of the burner 1. The cooling medium is sprayed on the combustion gas provided from (30) to serve to cool again.

Here, the cooling medium injected from the sixth to eighth injection nozzles 111, 112, and 113 is preferably an industrial cooling gas.

When the combustion chamber 110 discharges the combustion gas through the combustion gas outlet 114, the combustion gas outlet 114 suppresses dew condensation at the combustion gas outlet 114 due to a temperature difference with the outside. It is further provided with an air supply pipe 115 for supplying hot air to the adjacent portion.

In general, as the low temperature combustion gas cooled in the cooling chamber 110 exits through the combustion gas outlet 114, the temperature difference between the low temperature combustion gas and the outside at room temperature is higher than the combustion gas outlet 114. Condensation occurs in the water, and there is a problem that water is accumulated in the cooling chamber 110 due to the condensation.

That is, when water accumulates in the cooling chamber 110, the water not only increases the noise by disturbing the flow of the combustion gas, but also lowers the cooling efficiency of the cooling chamber 110.

In the present invention, since the hot air provided from the air supply pipe 115 adjusts the temperature of the combustion gas relatively similar to the normal temperature while contacting the combustion gas, the above problems can be sufficiently prevented.

The air supply pipe 115 is supplied with air from the cooling washing unit 30 of the burner (1). As such, in order to receive air from the cooling wash unit 30, the air supply pipe 115 may be connected to communicate with the cooling wash unit 30.

At this time, since the air supply pipe 115 is formed to be narrower than the cooling chamber 30 of the burner 1, the air is supplied from the cooling washing unit 30, that is, the purified combustion gas 110. It is preferable to design a small amount of purified combustion gas from the cooling washing unit 30. However, the air supply pipe 115 may be supplied with air from a predetermined heater device.

On the other hand, the storage tank 120 is provided in the lower portion of the cooling washing unit 30 of the burner 1 receives and receives the waste water and the residue mixed with water-soluble gas from the cooling washing unit 30.

In an embodiment, the reservoir 120 is made of a metal material but has a three-dimensional shape such as a rectangular parallelepiped shape and has a receiving space (not shown) for accommodating waste water and combustion residues mixed with a water-soluble gas therein.

Although not separately shown in the drawings, the reservoir 120 is preferably communicated with a separate sewer pipe (not shown) to discharge the waste water and combustion residues contained in the receiving space to the outside.

5 to 7, the gas scrubber 100 using the waste gas combustion burner 1 according to the present invention is a waste gas supply source (not shown) and the waste gas supply pipe 101 is a toxic waste gas burner (1). It is provided to the nozzle unit 10 of.

1 to 4, the waste gas flows into the waste gas inlet 11 of the nozzle unit 10, and the waste gas flows out of the waste gas outlet 12 along the first flow path 15.

At this time, the waste gas flowing out to the waste gas outlet 12 is the waste gas combustion gas flowing out to the waste gas outlet 12 along the second flow path 16 through the gas inlet 13, and through the catalyst inlet 14 It flows out while mixing with the catalyst which flows out into the waste gas outlet 12 along the three flow paths 17.

The waste gas, the waste gas combustion gas, and the mixed gas of the catalyst flow into the combustion space 23 of the combustion unit 20, and the mixed gas introduced into the combustion space 23 simultaneously with the ignition of the ignition plug 22. It will start burning.

During the combustion of the mixed gas, the first injection nozzle 27 of the cooling unit 26 continuously injects water into the inner cylinder 25.

The mixed gas combusted by the combustion unit 20 becomes a purified combustion gas, and the purified combustion gas flows into the cooling washing unit 30.

The purified combustion gas introduced into the cooling washing unit 30 is cooled by water and sodium hydroxide, which are cooling media injected from the second to fifth injection nozzles 31, 32, 33, and 32, and is included in the combustion gas. The water-soluble gas is dissolved in water, which is a cooling medium, and is removed, and the combustion residues flowing out of the combustion unit 20 are washed.

The purified combustion gas flowing out of the cooling washing unit 110 flows into the cooling chamber 110. The combustion gas introduced into the cooling chamber 110 is cooled to a low temperature due to the cooling medium injected from the sixth to eighth injection nozzles 111, 112, and 113 while passing through the curved interior.

In addition, the low-temperature combustion gas discharged to the combustion gas outlet 114 by moving inside the cooling chamber 110 is supplied by the air supplied from the cooling washing unit 30 of the burner 1 to the air supply pipe 115. It is controlled to be relatively similar to the outside temperature.

On the other hand, the waste water and the residue mixed with the water-soluble gas flowing out from the cooling washing unit 110 is introduced into the storage tank (120). Wastewater and debris introduced into the reservoir 120 are discharged to the outside through a separate sewage pipe.

The present invention relates to a burner for waste gas combustion, and because the nozzle portion is made of a mixture of waste gas, waste gas combustion gas, and catalyst, the waste gas is prevented from being concentrated in the center of the flame zone only along the flow direction of the flame. There is an excellent effect that can increase the flame stability by not generating a flame flying.

In addition, the burner for waste gas combustion according to the present invention increases the combustion temperature by increasing the combustion characteristics such as self-ignition of the waste gas combustion gas, flame propagation, etc., because the mixing of waste gas, waste gas combustion gas, and catalyst is made smoothly. This facilitates, thereby eliminating the incomplete combustion of the waste gas has an excellent effect of increasing the treatment efficiency.

In addition, the burner for waste gas combustion according to the present invention has an advantage of sufficiently preventing problems such as melting of the combustion chamber even at a high temperature of 1000 ° C. or more generated during combustion due to the ceramic cylinder and the cooling unit surrounding the combustion space.
