Description

Regenerative combustion oxidation device

The present invention relates to a regenerative combustion oxidation device with an improved structure of an opening and closing unit that controls the inflow of harmful gases.

Volatile organic compounds refer to hydrocarbons with a vapor pressure above 0.02 psi or a boiling point less than 100°C. If they coexist with nitrogen-containing compounds in the atmosphere, they will undergo a photochemical reaction through the action of sunlight to generate ozone and photochemistry. Oxide. Volatile organic compounds pollute the environment and cause respiratory disorders and carcinogens that are harmful to the human body.

For this reason, various methods for removing harmful gases containing volatile organic compounds are used on the industrial site.

The method for removing volatile organic compounds is a combustion oxidation method that directly burns to remove volatile organic compounds at a high temperature of about 800°C. In the case of the combustion oxidation method, volatile organic compounds are burned under high temperature conditions, and therefore, the exhausted purified gas is also in a high temperature state. However, if the waste heat of the discharged purge gas cannot be used, energy is wasted. Therefore, after the waste heat of the purge gas is recovered, a regenerative combustion oxidation device that preheats the inflowing volatile organic compounds is generally used.

In the conventional regenerative combustion oxidation device disclosed in Korean Patent Publication No. 10-1618718 (April 29, 2016), the inside of the main body 110 is divided into a plurality of regions 121, 122, 123, 124, 125, each The areas 121, 122, 123, 124, and 125 are respectively connected to the harmful gas inflow pipe 151 through which the harmful gas passes, the purge gas discharge pipe 154 through which the purge gas passes, and the purge gas supply pipe 157 through which the purge gas passes. Furthermore, each harmful gas inflow pipe 151, each purge gas discharge pipe 154, and each purge gas supply pipe 157 are independently opened and closed by the valve unit 160, respectively.

In the conventional thermal storage combustion oxidation device as described above, harmful gas may leak between the inner surface of the harmful gas inflow pipe 151 and the edge surface of the opening and closing plate 165 of the valve unit 160 that are in contact with each other. Therefore, in a state where the harmful gas inflow pipe 151 is closed by the valve unit 160, the harmful gas can flow into the body 110 through the harmful gas inflow pipe 151, and therefore, the exhausted purified gas may be discharged together with the harmful gas. Therefore, the reliability of the product will be reduced.

1 to 4, the operation of the regenerative combustion oxidation device according to an embodiment of the present invention will be described. Fig. 4 is a schematic plan view of the lower body shown in Fig. 2.

Hereinafter, based on the center of the lower body 115, harmful gas, purge gas, and purge gas circulate in the positive direction, which is a clockwise direction, and pass through the heat storage member 120 installed in each area 115a, 115b, 115c, 115d, and 115e in sequence. .

As shown in FIG. 4, the inside of the lower body 115 is divided into five areas 115a, 115b, 115c, 115d, and 115e, so n=3. Therefore, the harmful gas and the purified gas pass through two areas respectively, and can pass through symmetrical areas respectively.

The first opening and closing unit 150 to the third opening and closing unit 175 all take the closed state as the initial state.

In the initial state, the first opening and closing unit 150a, 150b and the second opening and closing unit 171c, 171d are adjusted to open the harmful gas pipes 141a, 141b and the purified gas pipes 143c, 143d, respectively, so that the harmful gas and the purified gas pass through the areas 115a, 115b and areas 115c and 115d.

Therefore, the harmful gas flows into the combustion chamber 111a through the areas 115a and 115b. The harmful gas flowing into the combustion chamber 111a moves along one side, upper surface and the other side of the combustion chamber 111a and is burned to become purified gas, and then passes through the area 115c. , 115d discharge. In this case, the heat storage members 120 in the regions 115c and 115d exchange heat with the purge gas to store heat.

In this state, if the third opening/closing unit 175e is opened, the purge gas flows into the area 115e through the purge gas pipe 145e, and thus the harmful gas remaining in the area 115e flows into the combustor 111a together with the purge gas. Therefore, the area 115e is in a clean state. In this case, it is preferable that the purge gas flows into the region 115e between the region 115a at the rearmost end through which the harmful gas passes and the region 115d at the frontmost end through which the purified gas passes. The purge gas may be purified air.

If the area 115e is in a clean state, the third opening and closing unit 175e is closed. After that, the purge gas pipe 143e is opened and closed by the second opening and closing unit 171e and the second opening and closing unit 171c, and the harmful gas pipe 141c is opened and closed by the first opening and closing unit 150c and the first opening and closing unit 150a. . Therefore, the harmful gas flows into the combustion chamber 111a through the areas 115b and 115c, and the purified gas is discharged through the areas 115d and 115e. The area 115e is in a state of being purified by the purge gas, and therefore, the purified gas discharged through the area 115e will not be mixed with harmful gases.

In this state, if the third opening and closing unit 175a is opened, the purge gas flows into the area 115a through the purge gas pipe 145a. Therefore, the harmful gas remaining in the area 115a flows into the combustion chamber 111a together with the purge gas. , The area 115a is in a clean state.

After that, the purge gas pipe 143a is opened and the purge gas pipe 143d is closed by the second opening and closing unit 171a and the second opening and closing unit 171d in sequence, and the harmful gas pipe 141d is opened and closed by the first opening and closing unit 150d and the first opening and closing unit 150b. . Therefore, the harmful gas flows into the combustion chamber 111a through the areas 115c and 115d, and the purified gas is discharged through the areas 115e and 115a. The area 115a is in a purified state by the purge gas, so the purified gas discharged through the area 115a will not be mixed with harmful gases.

By repeating the operations described above, the harmful gas is discharged together with the purge gas, and the heat storage member 120 stores heat by the purge gas.

In an embodiment of the heat storage combustion oxidation device of the present invention, the body 110 may be polygonal, and the heat storage member 120 may be a shape corresponding to each area 115a, 115b, 115c, 115d, 115e.

The harmful gas pipe 141 in the areas 115a, 115b, 115c, 115d, and 115e where the purified gas is discharged is closed. That is, the harmful gas pipes 141 of the regions 115a, 115b, 115c, 115d, and 115e where the purified gas is discharged are closed by the first opening and closing unit 150. However, if the harmful gas leaks at the position where the harmful gas pipe 141 of the first opening and closing unit 150 is installed, the harmful gas can flow into the areas 115a, 115b, 115c, 115d, 115e where the purified gas is exhausted. Therefore, the purified gas can interact with the harmful gas. The gas is mixed and discharged.

In the regenerative combustion oxidation device of an embodiment of the present invention, in order to prevent the exhausted purified gas from mixing with harmful gases, when the harmful gas pipe 141 is closed by the first opening and closing unit 150, the residual gas can be forcibly discharged to the outside through leakage or the like. The harmful gas of the first opening and closing unit 150.

The upper side and the lower side of the first opening and closing unit 150 can be respectively communicated with the upper side and the lower side of the harmful gas pipe 141, and a sealed space can be formed on the side of the central portion. Therefore, if the harmful gas pipe 141 is closed by the first opening and closing unit 150, the gas including the air remaining in the sealed space of the first opening and closing unit 150 can be forcibly discharged to the outside.

3 to 7, the first opening and closing unit 150 will be described. Fig. 5 is an exploded perspective view of the opening and closing unit shown in Fig. 2, and Figs. 6 and 7 are cross-sectional views taken along the line "A-A" in Fig. 5.

As shown in the figure, the first opening and closing unit 150 may include a frame 151 and an opening and closing member 153.

The frame 151 may have a hexahedral shape, and the cross-sectional shape may correspond to the cross-sectional shape of the harmful gas pipe 141. The upper surface and the lower surface of the frame 151 may be opened, and the upper and lower parts of the harmful gas pipe 141 may be respectively communicated with the open upper surface and the open lower surface of the frame 151. Therefore, the upper part and the lower part of the harmful gas pipe 141 communicate with each other through the frame 151 medium.

The hexahedron has 4 side plates. However, in one embodiment of the present invention, the frame 151 has three side plates, and one side can be open.

The opening and closing member 153 can be inserted into the inside of the frame 151 through the open side surface of the frame 151 and can move linearly in a form of entering and exiting the frame 151. Therefore, the opening and closing member 153 can communicate or block the upper and lower sides of the frame 151.

A space 153a sealed by the side surface of the frame 151 can be formed inside the opening and closing member 153. If the upper and lower sides of the frame 151 are blocked by the opening and closing member 153, the gas remaining in the space 153a of the opening and closing member 153 can flow to the frame 151. Exhaust from the outside.

The opening and closing part 153 may include an opening and closing plate 154 and a connecting plate 155.

The pair of opening and closing plates 154 face each other and have a space therebetween, and are inserted into the open side of the frame 151 and can move linearly in the form of entering and exiting the frame 151. The connecting plate 155 is located on the open side of the frame 151 to be exposed to the outside of the frame 151, and may be integrally connected with a pair of opening and closing plates 154. Therefore, when the opening and closing member 153 is inserted into the frame 151 to block the upper and lower portions of the frame 151, the space 153a of the opening and closing member 153 formed by the opening and closing plate 154 and the connecting plate 155 is sealed by the side surface of the frame 151. Then, if the upper and lower portions of the frame 151 are blocked by the opening and closing member 153, the gas remaining in the space 153a of the sealed opening and closing member 153 is forcibly discharged to the outside.

On the inner surface of the opposing side plates of the frame 151, the guide rails 151a may be formed to face each other, and the guide rails 151a may be inserted into the space formed on both sides of the pair of opening and closing plates 154. As a result, the opening and closing plate 154 is inserted into the guide rail 151a and supported, and therefore, the guide rail 151a guides and supports the linear movement of the opening and closing plate 154.

An insertion rail 151b may be formed on the inner surface of the side plate of the frame 151 facing the open side of the frame 151. Furthermore, when the upper and lower sides of the frame 151 are blocked by the opening and closing member 153, the insertion rail 151b can be inserted into the interval formed between the surfaces of the pair of opening and closing plates 154 facing the insertion rail 151b. Therefore, the upper and lower sides of the frame 151 can be stably blocked by the opening and closing member 153.

The insertion rail 151b may be formed continuously with the guide rail 151a.

A discharge hole 151c can be formed on one side of the frame 151. When the upper and lower parts of the frame 151 are blocked by the guide rail 151a, the discharge hole 151c discharges the space 153a existing in the opening and closing member 153 sealed by the side plate of the frame 151 to the outside. gas. One side of the discharge hole 151c may communicate with the space 153a of the opening and closing member 153, and the other side may communicate with the pump 161.

Therefore, when the purge gas is discharged to one area 115a, 115b, 115c, 115d, 115e formed in the main body 110, the harmful gas pipe 141 of the area where the purge gas is discharged is closed by the first opening and closing unit 150. However, if the harmful gas pipe 141 is closed by the first opening and closing unit 150, the gas in the space 153a of the opening and closing member 153 sealed by the frame 151 is discharged to the outside of the first opening and closing unit 150 by the pump 161.
