The present disclosure relates to a regenerative combustion device.

The description in this section merely provides background information on this disclosure and does not constitute prior art.

There are various types of combustion facilities that oxidize harmful gases including volatile organic compounds, which are emitted from industrial sites, into the atmosphere. However, there is a method of preheating the supply gas with high heat energy Is advantageous in terms of energy saving and harmful gas removal efficiency.

The regenerative combustion system allows the process gas to pass through the heat exchange layer before and after the combustion of the process gas, thereby regenerating and regenerating the residual heat of combustion. At this time, a normal regenerative combustion device uses a rotary rotor as a distributing mechanism for introducing and discharging a process gas. The regenerative combustion system includes an intake system for introducing the process gas, a rotation rotor for distributing the process gas introduced through the intake system, a heat exchange layer for heating the process gas introduced through the rotation rotor, And a combustion chamber for burning the process gas. The high temperature process gas burned in the combustion chamber is discharged to the outside through the heat exchange layer again. At this time, the residual heat of the process gas accumulates in the heat exchange layer, and the accumulated heat is preheated do.

When the heat storage material is clogged, And it is difficult to clean and replace the heat storage material, so that a lot of time and energy consumption are caused. In addition, when a gas containing a harmful compound flows in and clean air from which harmful compounds are removed flows through a rotating distributor included in a lower portion of the combustion facility, a certain gap with the main body is required for the distributor to rotate. There is a problem that the gas containing the harmful compound can be mixed with the clean gas through which the gas is discharged.

The prior art noxious gas combustion facility (Patent No. 0983812) has an advantage of easy maintenance including disassembly and assembly of the distributor, but it is not easy to replace the heat storage material due to adsorption of harmful compounds in the lower part of the heat storage material, There is a possibility that the process gas and the exhaust gas passing through the rotating body may be mixed with each other.

Another conventional heat storage type recuperative combustion apparatus (Patent No. 1655250) employs a heat storage member in a detachable form, which facilitates the replacement and cleaning of the heat storage material. However, the process gas and the exhaust gas passing through the rotating body There is a risk that it may become.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to overcome the disadvantages of the prior art described above by providing a method of removing harmful compounds adsorbed on a lower portion of a heat storage unit, And a sealing structure for preventing the process gas and the exhaust gas containing the impurities from being mixed with each other.

The process gas flowing into the main body 200 rises to the combustion chamber through the regenerator 210 and the process gas 800 is burned in the combustion chamber to decompose the organic compound. The clean gas, which is burned at a high temperature and contains high temperature thermal energy, can be descended again through the heat storage unit 210. And is cooled down after passing the thermal energy to the heat storage unit 210, so that it can escape through the communication pipe 330 of the communication body 300.

12, the vertical sealing member 710 may be fixedly coupled to a first vertical fixing bar 720 fixed to the outer peripheral blocking wall 452 with a second vertical fixing bar 730, And the other side can slide on the inner peripheral surface of the communication body 300. The other side of the vertical sealing member 710 extends upward and downward until it contacts the bonding member 623 of the horizontal fixing unit 620 of the horizontal sealing unit 600 disposed above and below the vertical sealing unit 700 Can be extended. This is because the other side of the vertical sealing member 710 is positioned above the vertical length of the first communication hole 310 or the second communication hole 320 to enhance the sealing effect between the communication body 300 and the rotating body 400 It is extended.

The horizontal sealing portion 600 may be disposed on the outer circumferential surface of each of the upper and lower shielding disks 420 and 430 and the vertical sealing portion 700 may be disposed between the shielding disks 420 and 430, May be disposed on the wall 452. 12, by the horizontal sealing part 600 disposed above and below the vertical sealing part 700 and the vertical sealing part 700, a gap exists in the rotating body 400 and the communication body 300 It is possible to prevent the process gas 800 and the exhaust gas 820 from being mixed. The sealing portions 600 and 700 of the regenerative combustion apparatus minimize the sealing area and maximize the effect of preventing the mixture of the process gas 800 and the exhaust gas 820. Therefore, It has a high mixing prevention effect.

It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure, It will be possible. The present embodiments are intended to illustrate and not to limit the technical spirit of the present disclosure, and thus the scope of the present disclosure is not limited by the present embodiment. The scope of protection of the present disclosure should be construed according to the scope of the claims, and all technical ideas which are deemed to be equivalent or equivalent should be construed as being included in the scope of the present disclosure.
