Abstract

A heat storage combustion and oxidization apparatus is disclosed. According to the present invention, the heat storage combustion and oxidization apparatus uses only a burner or both the burner and a heating element together as a heat source when the heat source is required to combust harmful gas, or uses the heating element at all other times. Such that, costs is reduced compared with the case of using the burner requiring relatively high costs. Moreover, the harmful gas is generated by combustion of the fuel when the burner is operated, while the harmful gas is not generated when the heating element performs heating. Such that, the present invention prevents clean gas from being contaminated as compared with the case of using only the burner.

Description

[0001] REGENERATOR COMBUSTION AND OXIDIZATION APPARATUS [0002]

The present invention relates to a regenerative burning oxidation apparatus using a burner and a heating element as a heat source for burning noxious gas.

A volatile organic compound is a hydrocarbon compound having a vapor pressure of 0.02 psi or more, or a boiling point of less than 100 ° C. When it coexists with a nitrogen compound in the air, it generates a photochemical reaction by the action of sunlight to generate ozone and photochemical oxide. Volatile organic compounds are not only substances that pollute the environment, but also harmful substances that cause respiratory tract disorders and carcinogens.

For this reason, industrial sites use various methods to remove harmful gases including volatile organic compounds.

There are combustion oxidation methods and catalytic oxidation methods for removing volatile organic compounds. In the combustion oxidation method, volatile organic compounds are directly burned at a high temperature of about 800 ° C to remove volatile organic compounds. The volatile organic compound is burned by using the catalyst to remove the volatile organic compound.

In the case of the combustion oxidation method in which the volatile organic compound is directly burned, since the volatile organic compound is burned at a high temperature, the discharged clean gas is also in a high temperature state. However, energy can be wasted if the waste heat of the discharged clean gas can not be used. Therefore, a regenerative burning oxidation apparatus for preheating the volatile organic compounds introduced after recovering the waste heat of the clean gas is widely used.

A conventional heat accumulation combustion oxidation apparatus disclosed in Korean Patent Laid-Open No. 10-2003-0011036 uses a burner as a heat source for burning noxious gas in the combustion chamber 10, as shown in FIG.

However, in the case of the burner, fuel is required, which is relatively expensive.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a regenerative combustion oxidizing apparatus capable of solving all the problems of the prior art as described above.

It is another object of the present invention to provide a regenerative combustion oxidizing apparatus capable of preventing contamination of clean gas by selectively using a burner and a heating element as a heat source for burning noxious gas.

According to an aspect of the present invention, there is provided a regenerative combustion oxidation apparatus comprising: a main body having a combustion chamber in which a noxious gas flows into a combustion chamber; Wherein the combustion chamber is provided at the other side of the main body of the combustion chamber and is divided into a plurality of zones and at least one of the plurality of zones is passed through the combustion chamber through the noxious gas, Wherein at least one of the at least one zone not passing through the combustion chamber is discharged through a clean gas generated due to the combustion of the noxious gas in the combustion chamber and the purge gas is passed through the one zone where the noxious gas and the clean gas do not pass, A heat storage member which is introduced into the combustion chamber together; A burner installed on an outer surface of the main body at the combustion chamber side and serving as a heat source for burning noxious gas introduced into the combustion chamber; And a heating element installed in the combustion chamber and serving as a heat source for burning the noxious gas introduced into the combustion chamber.

In the heat accumulating combustion oxidation apparatus according to the embodiment of the present invention, only a burner is used as a heat source for burning harmful gas, or a burner and a heating element are used together, and in other cases, a heating element is used. Then, the cost can be reduced as compared with the case where only a relatively expensive burner is used.

In operation of the burner, noxious gas is generated by the combustion of the fuel, but no noxious gas is generated when the heating element generates heat. In this case, the clean gas may be prevented from being contaminated as compared with the case where only the burner is used.

A heat storage member 120 formed of a ceramic material through which harmful gas, clean gas, and purge gas passes may be installed in the regenerative chamber. The heat accumulating member 120 may be partitioned into (2n-1) (n is a natural number of 2 or more) regions radially with respect to the center of the heat accumulating member 120. [

When the heat accumulating member 120 is divided into (2n-1) zones, the noxious gas can pass through (n-1) zones. The clean gas generated in the combustion chamber 111a by the combustion of the noxious gas can pass through the same (n-1) zones as the number of the zones through which the noxious gas passes, and the purge gas passes through one zone .

The heat accumulating member 120 is divided into a plurality of unit heat accumulating members 120a which are hollow hollow bodies having upper and lower openings so that noxious gas, clean gas and purge gas can pass through the heat accumulating member 120 . That is, a plurality of unit heat-accumulating members 120a are arranged in rows and columns, and a plurality of unit heat-accumulating members 120a arranged in rows and columns are stacked to form heat-accumulating members 120. [

Since the gas passes through the inside of the unit heat storage member 120a, the inside of the unit heat storage member 120a is pores.

The heat storage combustion oxidation apparatus according to the first embodiment of the present invention shows that the heat storage member 120 is divided into five zones 121, 122, 123, 124 and 125 having n = 3.

The partition 117 may be in contact with the inner surface and the upper surface of the upper main body 115 so that the heat storage member 120 can be divided into five zones 121, 122, 123, 124 and 125. Since the unit heat storage members 120a are arranged in rows and columns in the spaces partitioned by the partition walls 117, spaces defined by the partition walls 117 are formed in the spaces 121, 122, 123, 124, 125).

The lower surface of the heat accumulating member 120 may be supported by a support plate (not shown) of the mesh structure and spaced apart from the lower surface of the lower main body 115.

The heat accumulating member according to the first embodiment of the present invention is divided into five zones 121, 122, 123, 124, 125, so n = 3. Thus, the noxious gas can pass through two zones, the clean gas can pass through two zones where noxious gas does not pass, and the purge gas can pass through one zone where neither the noxious gas nor the clean gas passes .

At this time, it is preferable that the zone through which the noxious gas passes and the zone through which the clean gas passes are substantially symmetrical with respect to the center of the heat accumulating member 120. The noxious gas, the clean gas, and the purge gas can pass through the regions of the heat storage member 120, one by one, sequentially. That is, the harmful gas, the clean gas, and the purge gas can circulate through the region of the heat storage member 120, respectively, and the circulation directions of the harmful gas, the clean gas, and the purge gas are preferably the same.

The heat accumulating member 120 will be described later.

A first tank 141 may be installed outside the main body 110 and a second tank 143 (see FIG. 5A) may be partitioned from the first tank 141 into the first tank 141 Can be installed. That is, the noxious gas generated in the industrial site can be stored in the first tank 141, and the clean gas in the combustion chamber 111a generated by the combustion of the noxious gas can be accommodated and stored in the second tank 143 have. The harmful gas and the clean gas are stored in the first tank 141 and the second tank 143, respectively, so that they are not mixed.

Between the main body 110 and the first tank 141, noxious gas stored in the first tank 141 flows through the respective spaces 121, 122, 123, 124, 125 of the heat accumulating member 120 into the combustion chamber 111a A plurality of noxious gas inflow pipes 151 may be installed. The upper end side of the noxious gas inflow pipe 151 can communicate with the respective regions 121, 122, 123, 124 and 125 of the heat accumulating member 120 respectively and the lower end can communicate with the first tank 141 . The number of the noxious gas inlet pipes 151 may correspond to the number of the divided spaces 121, 122, 123, 124, 125 of the heat accumulating member 120.

Each of the noxious gas inlet pipes 151 may be provided with a first valve 152 for independently opening and closing the respective noxious gas inlet pipes 151. The noxious gas stored in the first tank 141 can be selectively introduced into each of the regions 121, 122, 123, 124 and 125 of the heat accumulating member 120 by the first valve 152.

The clean gas in the combustion chamber 111a is supplied to the second tank 143 through the respective sections 121, 122, 123, 124 and 125 of the heat accumulating member 120 between the main body 110 and the second tank 143, (See Fig. 5A). The upper end side of the clean gas discharge pipe 154 can communicate with the respective sides 121, 122, 123, 124 and 125 of the heat accumulating member 120 and the lower end can communicate with the second tank 143 have. The number of the clean gas discharge pipes 154 may correspond to the number of the divided spaces 121, 122, 123, 124 and 125 of the heat accumulating member 120.

Each clean gas discharge pipe 154 may be provided with a second valve 155 for independently opening and closing the respective clean gas discharge pipes 154. The clean gas in the combustion chamber 111a is selectively passed through the respective sections 121, 122, 123, 124, and 125 of the heat accumulating member 120 by the second valve 155 to enter the second tank 143 .

A ring-shaped third tank 145 for containing and storing the purge gas may be installed on the lower surface of the main body 110 to surround the noxious gas inlet pipe 151 and the clean gas discharge pipe 154.

One side of the third tank 145 communicates with each of the areas 121, 122, 123, 124 and 125 of the heat accumulating member 120 and the other side communicates with the third tank 145, A purge gas supply pipe 157 for introducing the purge gas of the tank 145 to the combustion chamber 111a through the respective sections 121, 122, 123, 124 and 125 of the heat accumulating member 120 may be provided . The number of the purge gas supply pipes 157 may be provided corresponding to the number of the divided regions 121, 122, 123, 124, 125 of the heat accumulating member 120.

Each purge gas supply pipe 157 may be provided with a third valve 158 that independently opens and closes each purge gas supply pipe 157. The purge gas of the third tank 145 is selectively passed through the respective sections 121, 122, 123, 124 and 125 of the heat accumulating member 120 by the third valve 158 to enter the combustion chamber 111a .

A communication duct 119 communicating with the respective sections 121, 122, 123, 124, 125 of the heat accumulating member 120 may be installed on a lower surface of the lower main body 115 of the main body 110, respectively. The upper ends of the noxious gas inlet pipes 151 corresponding to the respective sections 121, 122, 123, 124 and 125 of the heat accumulating member 120 can communicate with the communication ducts 119, ), And one end of the purge gas supply pipe 157 can communicate with each other.

It is preferable that the noxious gas inlet pipe 151 and the clean gas discharge pipe 154 are arranged radially with respect to the center of the heat storage member 120, respectively.

The burner 131 and the heating element 135 may be used as a heat source for burning the noxious gas introduced into the combustion chamber 111a.

The burner 131 is installed on the outer surface of the upper main body 111 of the main body 110 forming the combustion chamber 111a so as to heat and combust the noxious gas in the combustion chamber 111a and the heating body 135 is connected to the combustion chamber 111a So that the noxious gas can be heated and burned.

The burner 131 and the heating element 135 may be selectively operated by a control unit (not shown) or may be operated together if necessary.

More specifically, the control unit operates the burner 131 only when the temperature of the combustion chamber 11a is initially raised in order to burn the noxious gas at the time of initial operation of the regenerative combustion oxidizer, And the heating element 135 can be operated together. The controller may operate only the burner 131 or operate the burner 131 and the heating element 135 together if the temperature of the combustion chamber 111a is lower than the set temperature set for burning the harmful gas.

The burner 131 is relatively expensive because it uses fuel. However, in the heat accumulating combustion oxidation apparatus according to the first embodiment of the present invention, only the burner 131 is used or the burner 135 and the heating element 135 are used together, and in other cases, the heating element 135 is used The cost can be reduced.

At the time of operating the burner 131, noxious gas is generated by combustion of fuel, but no noxious gas is generated at the time of heat generation of the heat generating element 135. However, in the heat accumulating combustion oxidation apparatus according to the first embodiment of the present invention, only the burner 131 is used or the burner 131 and the heating body 135 are used together, and in other cases, the heating body 135 use. Therefore, a relatively small amount of noxious gas can be generated. Therefore, compared with the case where only the burner 131 is used, the clean gas can be prevented from being contaminated.

A plurality of burners 131 may be provided so that the combustion temperature can be uniform over the entire region of the combustion chamber 111a. The heating element 135 may be formed in a bar shape so that the combustion temperature can be uniform over the entire region of the combustion chamber 111a and may be radially provided with respect to the center of the heat storage member 120. [ At this time, the heating element 135 may be formed of molybdenum disilicide, which is a non-metallic material, or may be formed of any one selected from molybdenum, tungsten, and platinum, which are metal materials.

It is a matter of course that a sensor (not shown) for detecting the combustion temperature of the noxious gas may be installed in the upper body 111 where the combustion chamber 111a is formed.

The heat accumulating member 120 of the heat accumulating combustion oxidation apparatus according to the first embodiment of the present invention will be described with reference to Figs. 2 and 4. Fig. 4 is a schematic plan view of the heat accumulating member shown in Fig.

Hereinafter, the noxious gas, the clean gas and the purge gas are circulated in the clockwise direction with respect to the center of the heat accumulating member 120 and the regions 121, 122, 123, 124 and 125 of the heat accumulating member 120 Let's take a sequential passage through each example.

4, the heat accumulating member 120 is divided into five zones 121, 122, 123, 124 and 125, so that n = 3. Thus, it is preferred that the noxious gas and the clean gas each pass through two zones and pass through approximately symmetrical zones, respectively.

The operation of the heat accumulating member 120 will be described.

It is assumed that all of the first valve 152, all the second valves 155, and all the third valves 158 are closed. In the initial state, the first valves 152a and 152b and the second valves 155c and 155d are respectively connected to the first and second valves 152a and 152b so that the noxious gas and the clean gas can pass through the zones 121 and 222 and the zones 123 and 124, Open. The noxious gas then flows into the combustion chamber 111a through the spaces 121 and 122 and the noxious gas introduced into the combustion chamber 111a is burned while moving along one side surface and the upper surface and the other side surface of the combustion chamber 111a After being cleaned, it is discharged through zones 123 and 124. At this time, the spaces 123 and 124 of the heat accumulating member 220 through which the clean gas has passed through heat exchange with the clean gas to accumulate heat.

In this state, when the third valve 158e is opened, the noxious gas remaining in the zone 125 flows into the combustion chamber 111a together with the purge gas, so that the zone 125 is in a clean state. That is, the purge gas can be supplied to the combustion chamber 111a through the zone 125 located between the rearmost zone 121 through which the noxious gas passes and the most distant zone 124 through which the clean gas passes.

The purge gas may be clean air.

The second valve 155e and the second valve 155c are opened and closed respectively and the first valve 152c and the first valve 152a are opened and closed, respectively, when the zone 125 is in a clean state, do. The noxious gas then passes through the zones 122 and 123 into the combustion chamber 111a and the clean gas passes through the zones 124 and 125 and is discharged. The zone 125 is clean by the purge gas, so that the noxious gas is not mixed into the clean gas discharged through the zone 125.

Subsequently, the second valve 155a and the second valve 155d are opened and closed and the first valve 152d is closed after the third valve 158a is opened and the third valve 158e is closed, And the first valve 152b are opened and closed. The noxious gas then passes through the zones 123 and 124 into the combustion chamber 111a and the clean gas passes through the zones 125 and 121 and is discharged. The zone 121 is clean by the purge gas, so that the noxious gas is not mixed into the clean gas discharged through the zone 121.

Figs. 5A and 5B are partially cutaway perspective views of the first tank and the second tank shown in Fig. 1, which will be described.

5A, a second tank 143 is partitioned inside the first tank 141, and the first tank 141 and the second tank 143 may be concentric. At this time, the noxious gas inflow pipe 151 may be located outside the clean gas discharge pipe 154 with respect to the center of the heat accumulating member 120 (see Fig. 2).

The incoming harmful gas is burned at high temperature and then becomes clean gas. Therefore, the volume of the clean gas discharged compared to the volume of the introduced noxious gas is further increased. If the diameter of the clean gas discharge pipe 154 is larger than the diameter of the harmful gas inlet pipe 151, the clean gas can be easily discharged.

For this reason, as shown in FIG. 5B, the first tank 141 is partitioned inside the second tank 143, and the second tank 143 and the first tank 141 are concentric with each other . At this time, the clean gas discharge pipe 154 may be positioned outside the noxious gas inlet pipe 151 with respect to the center of the heat accumulating member 120 (see FIG. 2).

Since the space adjacent to the edge of the heat accumulating member 120 is wider than the center of the heat accumulating member 120, the diameter of the clean gas discharging pipe 154 can be increased without restriction of the installation space .

Second Embodiment

FIG. 6 is a schematic plan view of a heat accumulating member of the regenerative thermal oxidizer according to the second embodiment of the present invention, and only differences from the first embodiment will be described.

The heat accumulating member 220 according to the second embodiment of the present invention can be divided into five zones 221, 222, 223, 224 and 225 having n = 3, The outer surface of the heat accumulating member 220 facing the side surface of the main body 115 (see FIG. 2) may be formed in a pentagonal shape corresponding to the divided number of the heat accumulating member 220. At this time, the side surface of the lower main body 115 may also be formed in a pentagon corresponding to the outer surface of the heat storage member 220.

Since the outer circumferential surfaces of the respective zones 221, 222, 223, 224 and 225 of the heat accumulating member 220 are formed in a straight line, the unit heat accumulating members 220a and the lower heat collecting members 220a, The space that is formed between the side surfaces of the main body 115 is reduced. Therefore, the heat storage efficiency of the heat storage member 220 can be improved because the unit heat storage members 220a can be arranged in the respective zones 221, 222, 223, 224, and 225 of the heat storage member 220 in a concentrated manner.

Third Embodiment

FIG. 7 is a schematic cross-sectional view of a heat storage member of the heat accumulation combustion oxidation apparatus according to the third embodiment of the present invention, and only differences from the first embodiment will be described.

As shown in the figure, the heat accumulating member 320 can be divided into 2n (n is a natural number of 2 or more) regions radially with respect to the center of the heat accumulating member 320. [ When the heat accumulating member 320 is partitioned into 2n zones, the noxious gas can pass through (n-1) zones. The clean gas generated in the combustion chamber 111a (see FIG. 3) by the combustion of the noxious gas can pass through the same (n-1) zones as the number of the zones through which the noxious gas passes, Lt; / RTI >

The thermal storage combustion oxidation apparatus according to the third embodiment of the present invention shows that the heat storage member 320 is divided into four zones 321, 322, 323, and 324 having n = 2. Thus, the noxious gas can pass through one zone, the clean gas can pass through one zone where noxious gas does not pass, and the purge gas can pass through any zone where neither the noxious gas nor the clean gas passes can do.

The operation will be described.

It is assumed that all of the first valve 352, all the second valves 355 and all the third valves 358 are closed. The first valve 352a and the second valve 355c are opened respectively so that the noxious gas and the clean gas can pass through the zone 321 and the zone 323 respectively. The noxious gas flows into the combustion chamber 111a through the zone 321 and the noxious gas introduced into the combustion chamber 111a is combusted while moving along one side surface and the upper surface and the other side surface of the combustion chamber 111a, And the clean gas is discharged through the zone 323. At this time, the zone 323 of the heat accumulating member 320 through which the clean gas passes is heat-exchanged with the clean gas to accumulate heat.

In this state, the third valve 358d of the zone 324 located between the rearmost zone 321 through which the noxious gas passes and the most distant zone 323 through which the clean gas passes is opened and the purge gas The noxious gas remaining in the zone 324 flows into the combustion chamber 111a together with the purge gas, so that the zone 324 is in a clean state.

When the zone 324 is in a clean state, the second valve 355d is opened and the second valve 355c is closed, and the first valve 352b is opened and the first valve 352a is closed. Then, the noxious gas passes through the zone 322 and into the combustion chamber 111a, and the clean gas passes through the zone 324 and is discharged. Since the zone 324 is clean by the purge gas, the clean gas discharged through the zone 324 is not mixed with the noxious gas.

Thereafter, after the third valve 358a is opened and the third valve 358d is closed, the second valve 355a is opened, the second valve 355d is closed, and the first valve 352c Is opened and the first valve 352b is closed. Then, the noxious gas passes through the zone 323 and flows into the combustion chamber 111a, and the clean gas passes through the clean zone 321 and is discharged.

The outer surface of the heat accumulating member 320 opposing the side surface of the lower main body 115 (see Fig. 2) of the main body 110 is covered with the outer surface of the heat accumulating member 320, And may be formed in a 2n square shape corresponding to the number of the divided regions of the heat accumulating member 320. [ The side surface of the lower main body 115 may also be formed in a 2n square shape corresponding to the outer surface of the heat storage member 320. [
