[0031] The side wall of the gas distribution module (20) is adjacent to the side wall of the combustion chamber (10). Therefore, the length (L2) of the gas distribution module (20) can be the same as the length (L1) of the combustion chamber (10). Specifically, the gas distribution module (20) and the combustion chamber (10) are manufactured separately, and then transported to the installation site for connection to make them communicate. The structure of the two modules adjacent to each other reduces the height of the regenerative thermal oxidation device, and each module can be loaded into a transport vehicle or a container for transportation, and assembled by bolt connection at the installation site, so that transportation and installation are very easy.

[0032] The bed module (30) comprises a plurality of beds (300). The plurality of beds (300) are arranged in sequence along the length (L1) of the combustion chamber. The heat insulation component (130) is arranged between the bed module (30) and the inner surface of the combustion chamber (10) (see Figure 3 and 4 ). In one embodiment, the gas distribution module (20) can comprise a plurality of gas distribution units (200). The gas distribution units (200) are arranged along the length (L2) of the gas module, and the gas distribution units (200) are arranged corresponding to each of the plurality of beds (300).

[0033] The gas distribution unit (200) includes a gas supply unit (201), a gas exhaust unit (202), and a purge unit (203).

The gas supply unit (201), the gas exhaust unit (202), and the purge unit (203) can be arranged between the lower gas chamber (210) and the upper gas chamber (220) described later.

[0034] Figure 4 is Figure 1 is a front view of the lower gas chamber (210) shown in FIG. 2. Figure 5 is Figure 3 is a front view of the lower gas chamber (210) shown in FIG. 2.

[0035] As shown in FIG. 2, the gas distribution module (20) includes a lower gas chamber (210) and an upper gas chamber (220).

[0036] The upper gas chamber (220) includes a gas supply duct (221), a gas exhaust duct (222), and a purge duct (223). The gas supply duct (221) is connected to the gas supply unit (201). The gas exhaust duct (222) is connected to the gas exhaust unit (202). The purge duct (223) is connected to the purge unit (203).

[0037] Each of the gas supply duct (221), the gas exhaust duct (222), and the purge duct (223) extends in parallel along the combustion chamber length (LI). The length of each of the gas supply duct (221), the gas exhaust duct (222), and the purge duct (223) can be equal to the combustion chamber length (LI). In one embodiment, one side wall of the gas exhaust duct (222) is adjacent to a side wall of the combustion chamber (10). One side wall of the gas supply duct (221) is adjacent to the other side wall of the gas exhaust duct (222). One side wall of the purge duct (223) is adjacent to the other side wall of the gas supply duct (221). The gas supply duct (221) is disposed between the gas exhaust duct (222) and the purge duct (223). Accordingly, the width of the lower gas chamber (210) can be set to be smaller than the width of the upper gas chamber (220), i.e., the size can be minimized and the equipment cost can be reduced.

[0038] ​The gas supply unit (201) can include a supply pipe (2011), a supply valve (2012), and a supply valve driving part (2013). The supply pipe (2011) extends from the gas supply pipe (221) to the lower gas chamber (210). The supply valve (2012) is disposed in the supply pipe (2011) and adjusts the supply of harmful gas. The supply valve driving part (2013) can drive the supply valve (2012).

[0039] The gas exhaust unit (202) can include an exhaust pipe (2021), an exhaust valve (2022), and an exhaust valve driving part (2023). The exhaust pipe (2021) extends from the gas exhaust pipe (222) to the lower gas chamber (210). The exhaust valve (2022) is disposed in the exhaust pipe (2021) and adjusts the exhaust of combustion gas. The exhaust valve driving part (2023) can drive the exhaust valve (2022).

[0040] The purge supply unit (203) can include a purge pipe (2031), a purge valve (2032), and a purge valve driving part (2033). The purge pipe (2031) extends from the purge pipe (223) to the supply pipe (2011). The purge valve (2032) is disposed in the purge pipe (2031) and adjusts the supply of purge gas. The purge valve driving part (2033) can drive the purge valve (2032).

[0041] The combustion chamber (10) includes a combustion space (110), an inflow-outflow space (120), and a combustion chamber partition (100). The combustion space (110) is disposed at the upper side of the combustion chamber (10). The bed module (30) is disposed at the lower portion of the combustion space (110). The inflow-outflow space (120) is disposed at the lower portion of the bed module (30). The plurality of combustion chamber partitions (100) can divide the bed module (30) into a plurality of beds (300). In addition, the plurality of combustion chamber partitions (100) extend to the inflow-outflow space (120) and divide the inflow-outflow space (120) into a plurality of inflow-outflow spaces (120). The plurality of inflow-outflow spaces (120) correspond one-to-one to the plurality of beds (300).

[0042] The lower gas chamber (210) includes a lower gas chamber partition (211). The lower gas chamber partition (211) is disposed on the extension line of the combustion chamber partition (100). The plurality of combustion chamber partitions (100) can divide the lower gas chamber (210) into a plurality of lower gas spaces. The plurality of lower gas spaces correspond one-to-one to the plurality of inflow-outflow spaces (120).

[0043] The lower gas chamber (210) has holes corresponding to the plurality of lower gas spaces. The combustion chamber (10) has holes corresponding to the plurality of inflow and outflow spaces (120). The holes of the lower gas chamber (210) are connected to the holes of the combustion chamber (10). Thus, in the case of a large capacity device, the gas distribution module (20) is manufactured in a module form and delivered to the installation site, and then can be easily connected to the combustion chamber (10). For a small capacity device, the gas distribution module (20) and the combustion chamber (10) can be combined as a whole and manufactured in a factory, and then placed in the installation position to complete the installation, which is very convenient. One lower gas space is connected to one gas supply part (201) and one gas discharge part (202).

[0044] The valve module type thermal oxidation device (1) according to one embodiment of the present application includes a gas supply fan (40), a purge fan (50), a chimney (60), and a fuel supply module (70). In one embodiment, the gas supply fan (40) can be disposed at one end of the gas distribution module (20) in the direction of the length (L1) of the combustion chamber. The harmful gas supplied from the gas supply fan (40) flows longitudinally along the gas supply duct (221).

[0045] The purge fan (50) can be disposed opposite to the gas supply fan, with the gas distribution module (20) disposed therebetween. The purge gas supplied from the purge fan (50) flows longitudinally along the purge duct (223). The chimney (60) can be disposed on either side of the gas supply fan (40) and the purge fan (50). The chimney (60) is connected to the gas discharge duct (222), and the flue gas discharged from the gas discharge duct (222) is discharged into the atmosphere through the chimney (60). The fuel supply module (70) can be disposed opposite to the chimney (60). Thus, the combustion chamber (10) and the gas distribution module (20) can be manufactured in a module form, facilitating transportation and installation. The fuel supply module (70) can supply fuel to the burner (700) disposed inside the combustion chamber (10). The burner (700) can heat the temperature inside the combustion chamber (10) to 800 degrees Celsius or more, allowing the harmful gas to be sufficiently combusted and discharged.

[0046] Harmful gas is supplied from a gas supply fan (40) to a gas supply duct (221), and the harmful gas in the gas supply duct (221) flows into the lower gas chamber (210) in accordance with the operation of the supply valve (2012). The harmful gas contained in the lower gas chamber (210) flows toward the flow-in and out space (120). The harmful gas is supplied from the flow-in and out space (120) to the bed (300). The harmful gas is preheated by the heat stored in the bed (300), and the harmful gas preheated by the bed (300) enters the combustion space (110) to be combusted. The combusted gas flows through the bed (300) again, and then flows toward the flow-in and out space (120) and the lower gas chamber (210). The gas entering the lower gas chamber (210) flows into the gas discharge duct (222) through the discharge valve (2022) and is discharged to the atmosphere through the chimney (60).

[0047] The control unit can control the supply valves (2012), the discharge valves (2022), and the purge valves (2032). For example, one of the plurality of supply valves (2012) can be opened and the rest can be closed. Similarly, the plurality of discharge valves (2022) and the plurality of purge valves (2032) can be controlled. Thus, the control unit can control a part of the plurality of beds (300) to receive the harmful gas, a part to discharge the combusted gas, and the rest to receive the purge gas.

[0048] The valves described in the present specification can include various types of valves. For example, the valves shown in the drawings are butterfly valves. However, the valves are not limited to the butterfly valves, and various types of valves such as poppet valves can be applicable.

[0049] The above describes the present invention completed by the present inventor in detail according to the above-described embodiments, but the present invention is not limited to the above-described embodiments, and various changes can be made within the scope of the gist.

[0050] Obviously, the above-described embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or modifications can be made by those skilled in the art. Here, it is not necessary and impossible to exhaust all the embodiments.
