Description

Removable rotary valve having fine purging means for regenerative combustion apparatus

The present invention relates to a separate rotary valve for changing the wind direction of a regenerative combustion device having a fine purge means, and in detail, a separate rotary valve installed in a wind direction switching device configured to be mounted and detached to a regenerative combustion device has exhaust gas and air supply. The present invention relates to a rotary valve provided with a fine purge means to prevent fine leakage in the FCDPR SEAL and CR SEAL formed to prevent mixing between gases.

In the process of treating volatile organic compounds (VOC) or waste gas generated in a factory, it may be burned at a high temperature (about 800 ° C) or at a low temperature (about 350 ° C) using a catalyst.

At this time, since the treated gas has a high heat, there is a method of recovering the waste heat by using a general heat exchanger or a heat storage material. A high heat recovery is possible by using a double heat storage material.

Thus, there is a regenerative combustion device that burns by using a heat storage material, and a regenerative catalytic combustion device that uses a catalyst. The heat storage material is composed of a bed (Bed) for storing heat and a layer (Bed) for radiating heat from heat. It is operated by receiving heat from the layer and raising the temperature from the other room to the processing temperature and then heating the heat storage layer. The heat storage layer and the heat radiation layer are periodically replaced.

Periodic replacement of the heat accumulating layer and the heat dissipating layer requires a valve that converts the wind direction of the gas to be treated, which includes a bed and a cylinder.

Bed type has two or three air supply valve discharge valves attached to one bed, so there are a large number of valves and converts (open and close) every 1 ~ 2 minutes, so there is a problem of life and leakage. Momentary pressure fluctuations can be a problem for the process.

And the prior art using the cylindrical, there is the Republic of Korea Utility Model Registration No. 20-0199716, the cylindrical portion is a cylindrical portion is the cylindrical portion and the heat storage layer and the heat dissipating layer in the core portion at the center of the periodic replacement Rotating wind direction switching valve is attached, but it is inserted into the center core of lower part of heat storage cylinder, so it is difficult to repair in case of failure, and the rotating body and the fixed part are worn out by friction when rotating. Emissions to the atmosphere can cause environmental problems.

In the cylindrical rotary wind direction converter, the untreated gas flows in and the discharged gas flows out from each other when the wind direction is changed. There was a disadvantage.

Figure 1a is a perspective view of a rotary valve having a fine purge tube for FCDPR SEAL according to the present invention, Figure 1b is a top cross-sectional flat structure of a rotary valve having a fine purge tube for FCDPR SEAL according to the present invention, Figure 1c Figure 2 is a schematic illustration showing a front sectional structure of a rotary valve with a fine purge tube for FCDPR SEAL according to the present invention is assembled.

As shown in the present invention, the rectangular heat storage material or the fan-shaped heat storage material is stored in the heat storage layer 10 and the catalyst layer in the rectangular columnar or cylindrical combustion apparatus as disclosed in FIGS. 3A to 3D, 4A to 4D, and 5 described above. The present invention relates to a rotary valve used in a device in which a vertical or horizontal wind direction changer is disposed on the bottom side and is separately assembled to reduce the size of the equipment, improve the efficiency of exhaust gas treatment, and improve the ease of maintenance.

That is, the present invention is composed of a two-stage cylindrical structure that rotates in the interior of the separation chamber 100, the separation partition 210 is divided into the air supply and exhaust for the inside, one end is formed in the peripheral portion open However, the dead zone 250 is formed on the air supply boundary side, and the purge zone 260 is formed symmetrically on the exhaust boundary side, and the other end of the air supply side 1/2 is open around the cylindrical structure based on the divided partition. And an air supply port 221 is formed, and the other exhaust side 1/2 is composed of a valve exhaust case 211 in which a disc side of the cylindrical structure is opened to form an exhaust port 222, and provides an rotational force to such a configuration.

It is a rotary valve which prevents the leakage of fine gas which has not been achieved in the prior art by forming a fine purge tube and a fine purge groove which serve as a fine purge function in this structure. Reference numerals not shown in the following description refer to FIGS. 3A to 3D, 4A to 4D, and 5.

First, the configuration of the rotary valve of the present invention including the fine purge pipe 4021 will be described.

It is formed on the side of FCDPR SEAL (215) installed in one place in total.

To this end, the FCDPR SEAL support 216 into which each FCDPR SEAL 215 is inserted is divided into upper and lower portions, and a micro purge tube 4021 is formed therebetween. The purge air supplied to the fine purge pipe 4021 is supplied through the air supply passage 402. For this purpose, the air supply passage 402 is processed to branch at the point where the FCDPR SEAL 215 is installed.

At this time, at least one branched number at the point where each FCDPR SEAL 215 is installed is sufficiently sealed by the pressure of the purge air, but it is preferable to arrange a plurality of branches to supply the purge air quickly. In the present invention, it is configured to distribute and supply purge air by dividing into four circular arrangement.

The purge air supplied by the fine purge pipe 4021 is discharged into the gap 214 between the FCDPR SEAL support 216 and the FCDPR SEAL 215 to form a pressure higher than the air supply or exhaust gas flowing from the upper and lower parts, thereby forming a higher pressure. This prevents mixing between different incoming gas components from each other.

Therefore, even when the rotary valve FCDPR SEAL 215 is installed without forming a circle when the rotary valve is rotated, it may be introduced into the gap between the separation chamber barrel 103 and the exhaust chamber barrel 105 in the gap between the up and down directions. Fine supply and exhaust gases will prevent mixing at the source.

In addition, the configuration of the rotary valve of the present invention including the fine purge grooves 2521 and 2621 will be described below.

Figure 2a is a perspective view of a CR SEAL formed with a micro purge groove for CR SEAL according to the present invention, Figure 2b is a front sectional structure of the rotary valve having a CR SEAL formed with a micro purge groove for CR SEAL according to the present invention It is a schematic illustration shown.

The fine purge grooves 2521 and 2621 are formed at the upper and lower sides of the CR SEALs 252 and 262, respectively. The number of the fine purge grooves 2521 and 2621 is the upper and lower portions of the CR SEALs 252 and 621, respectively. It is preferable to install at least two of them in order to prevent multiple air supply or exhaust gases flowing in the horizontal direction.

The purge air supplied to the fine purge grooves 2521 and 2621 is supplied through the air supply passage 402. The air supply passage 402 is provided with at least one purge air discharge port at a point where the CR SEALs 252 and 262 are installed. It was processed to discharge through 403.

In addition, the dead zone block 251 and the purge zone block 261 supporting the purge air to be supplied to the CR SEAL 252 installed at the dead zone 250 and the CR SEAL 262 installed at the purge zone 26. The back branch of the was opened. Through this, purge air is supplied to the CR SEALs 252 and 262 so that the CR SEALs 252 and 262 contacting the separation chamber barrel 103 rotate in one direction, and the gap between the FCDPR SEAL supports 216 located on the upper and lower surfaces thereof. The supply or exhaust gas introduced through the 214 is not introduced by the pressure difference with the purge air supplied to the gap 214 through the fine purge grooves 2521 and 2621 so that the separation chamber barrel 103 is perpendicular to the separation chamber barrel 103. Through the minute gap of the upper surface or the lower surface of the CR SEAL (252, 262) in contact with the horizontal direction to avoid the conventional problem of mixing the exhaust gas and the supply gas.
