Horizontally distributed regenerative combustion plant {HORI. DISTRIBUTION TYPE REGENERATIVE THERMAL OXIDIZER}

The present invention inhales harmful gases generated in a plant using a volatile organic compound (V.O.C), passes through a heat storage layer in which a plurality of advanced ceramic materials (Ceramic) are laminated, and then passes the V.O.C. The present invention relates to a regenerative thermal oxidizer (RTO) for burning and purifying gas, and more particularly, a plurality of partitions are provided horizontally inside the regenerative combustion apparatus (RTO). It is rotated at and the supply of VOC gas is always half of the heat storage layer is preheated, and half of the heat recovery is repeated to prevent unnecessary waste of energy and complete combustion of harmful gases, thereby improving the efficiency of the equipment. It relates to horizontally distributed regenerative combustion equipment.

Generally, various types of regenerative combustion equipment (R.T.O) for burning off volatile organic compounds (VOC) (hereinafter referred to as "harmful gases") have been disclosed.

For example, as shown in (a) of FIG. 1A, "regenerative combustion equipment" of US Patent No. 5,562,442 has been disclosed. The contents are as follows.

In a heat storage combustion apparatus (RU) having a housing (HS) extending to the lower (LA), the central portion (CA) and the upper portion (UA) to introduce and process the harmful gas, and discharge the discharge gas,

Inlet gas inlet (IL) for introducing harmful gas, purge gas outlet (GO) for discharging clean gas, and lower portion (LA) having a space (FN) formed as a purge gas outlet (CO), lower portion (LA), upper portion The central part CA and the central part CA for inducing harmful gas introduced from the lower part LA adjacent to the UA to the upper part UA and leading clean gas processed from the upper part UA to the lower part. ), The gas flowing through the heat accumulating material (MM) with the burner (BN) provided in the upper portion to purify, and the upper portion (UA) for guiding the treated gas to the central portion (CA), and the space (PLENUM) Located at the bottom with (FN), receives the harmful gas from the inlet gas inlet (IL), distributes the harmful gas to the central portion (CA) and the treated gas from the central portion (CA) the purge gas outlet (GO) And a rotary distributor (RD) having a vertical axis of rotation (RS) and a noxious gas in the space (FN). The harmful gas distribution surface (DS) on which the rotating shaft (RS) is inclined to guide to CA, and the rotary distributor (RD) for guiding the gas treated from the central portion (CA) to the exhaust gas outlet (OL). The exhaust gas chamber (CB) with the, and the purification gas chamber (CC) with the rotary distributor (RD) to guide the treated gas from the central portion (CA) to the purification gas outlet (CO).

In addition, as shown in b), the purge gas outlet CO is a harmful gas remaining by the purge gas purging the noxious gas when the rotary distributor RD reaches the dividing unit SS. By discharging, the divided harmful gas layer BG and the gas of the purified gas layer CG are not mixed with each other.

However, as shown in Fig. 1B, the inner circumferential portion of the combustion body main body MF when the heat accumulating material MM formed of a cube, that is, a honey comb made of ceramic material, is laminated. The space (ES) is formed in each partition wall (usually 12 equal parts), and the heat storage area is reduced by blocking the lower part of the rotor with an iron plate so that no harmful gas leaks into the space ES.

In addition, since the inlet and outlet of the harmful gas and the clean air occur simultaneously with the center tube of the rotor processing apparatus formed in a circular shape, there is a limit of the throughput of inflow and outflow, and thus there is a problem that the throughput of the harmful gas decreases.

In addition, the area of the heat storage layer around the rotor is larger than that of the rotor provided in the center, and thus it does not evenly pass the entire area of the heat storage layer due to the inflow of harmful gas and the flow of clean air to both sides of the rotor in cross section. There was a problem that the heat exchange efficiency decreased and became unstable.

In addition, since the inflow of harmful gas and the discharge of clean air are made on both sides of the cross section of the center tube of the rotor, there is a problem that the throughput is smaller than the size of the facility.

The present invention has been made to solve the above problems, an object of the present invention is to purify by introducing the purge of the clean air discharged into the atmosphere to prevent the mixing of the harmful gas and clean air, the harmful gas and the clean air It is intended to prevent mixing at the source.

In addition, another object of the present invention is to increase the heat storage area of the heat storage layer to maximize the throughput of harmful gases compared to conventional treatment equipment having the same size.

In addition, another object of the present invention, as described above, to minimize the installation of the harmful gas and the clean air to the inlet and discharge of the harmful gas at a predetermined equal interval so as to provide a horizontal horizontal rotor to maximize the throughput of the harmful gas, Compared to the miniaturized equipment, the treatment efficiency is to be large.

In addition, the rotor is provided horizontally to allow the harmful gas and clean air to pass evenly across the heat storage layer to maximize the thermal efficiency area.

As shown in FIG. 2 and FIG. 3, it demonstrates in detail about the structure of the thermal storage type combustion installation 1 (henceforth a "combustion installation") of this invention.

As shown in Fig. 2 and Fig. 3, the regenerative combustion facility 1 of the present invention is provided with a rotor 100 in the longitudinal direction under the rectangular body 1a.

At both ends of the rotor 100, first and second blowers 101 and 102 are provided at both ends for supplying harmful gases of the factory, thereby supplying the harmful gas to the inner tube 110 of the rotor 100.

On the other hand, the rotor 100 has a dual structure of the inner tube 110 and the outer shell 120, the outer shell 120 is provided on the outer periphery of the inner tube 110 at predetermined intervals, the inner tube 110 is circular The first discharge holes 111 are formed at predetermined equal intervals at each position divided into six equal portions from the center in the cross section.

In other words, as shown in one side of FIG. 2, if the first discharge hole 111 of the uppermost end is formed in the first zone, the first discharge hole (the second discharge hole) is formed in the second space of the partition 200 to be described later. 111 is formed, and gradually to the rear end is formed in the third to sixth zone is formed on the outer periphery of the inner tube 110 as if it is a spiral.

In addition, the exterior 120 provided on the outer circumference of the inner tube 110 has a second discharge hole 121 is formed at each position at the same position as the first discharge hole (111).

The connecting plate 111a is mounted between the first and second discharge holes 111 and 121 so that harmful gas passing through the first discharge hole 111 is discharged to the second discharge hole 121, which will be described later. The partition serves as a partition so as not to mix with the clean air flowing into the inlet 122 of the exterior 120, and also serves to reinforce the interior and exterior of the exterior 110 and 120. Hereinafter, the first and second discharge holes 111 and 121 will be referred to as discharge holes 111 and 121 for convenience.

In addition, an inlet hole 122 is formed at an opposite side of each of the discharge holes 111 and 121 to pass through the discharge holes 111 and 121 and pass through the heat storage layer 3 and the combustion chamber 2 described later. The ball 122 is introduced between the inner tube 110 and the exterior 120 and moves to both ends of the exterior 120 and is discharged into the atmosphere.

On the other hand, the outer circumference of the rotor 100 is supported by the support hole 210 of the partition wall 200, although not shown, the packing (Packing) between the appearance 120 and the support hole 210 of the rotor 100 It is provided to facilitate the rotation of the rotor 100, but to maintain the airtight between the partition 200 formed a plurality of compartments.

The first purge plate 220 is mounted horizontally in a longitudinal direction at an upper side of the support hole 210, that is, at a position where the center line and the one end thereof coincide in cross section, and face the first purge plate 220. The second purge plate 230 is mounted on the other side of the lower portion. (Hereinafter, the first and second purge plates 220 and 230 are referred to as purge plates 220 and 230 for convenience. Explain.)

The purge plates 220 and 230 are formed to have the same inner diameter as the outer diameter of the outer shell 120 of the rotor 100 and thus does not affect the rotation of the rotor 100.

The partition wall 200 extends to an upper combustion chamber 2 to prevent mixing of harmful gas and clean air passing through each of the inflow holes 122 and the discharge holes 111 and 121, and the lower side of the combustion chamber 2. The heat storage layer 3 is provided with a plurality of heat storage materials made of ordinary honeycomb.

When the partition wall 200 is viewed in a plan view, when a plurality of cells are formed in a rectangular structure and the heat storage material 3a formed of a regular cube is provided, the heat storage material 3a is closely adjacent to each other and there is no gap. By increasing the heat storage area without dead space, the heat storage area becomes larger even if manufactured to a smaller size than the conventional circular equipment.

The partition plate 240 is installed at the center of the partition wall 200 to prevent mixing of harmful gas and clean air passing through the discharge holes 111 and 121 and the inlet hole 122 formed in a symmetrical manner.

Meanwhile, when the discharge holes 111 and 121 and the inlet hole 122 are covered by the purge plates 220 and 230 at the lower side of the main body 1a, that is, the lower side of each partition wall 200, the inflow and discharge are not performed. Some of the clean air discharged into the atmosphere is blown out by the purge blower 330 which will be described later to blow the residual gas into the combustion chamber (2) above the heat storage layer (3) the position of the discharge hole (111, 121) and inlet hole 122 When is changed, a purge device 300 is provided to prevent mixing.

In other words, the purge device 300 is unburned harmful when the rotor 100 is rotated and the discharge holes (111, 121) and the inlet hole (122) changes the position based on the partition plate 240 The discharge holes 111 and 121 and the inlet hole 122 are blocked by the first and second purge plates 220 and 230 to prevent the gas from being discharged into the atmosphere through the inlet hole 122 through which clean air is introduced and discharged into the atmosphere. When the inflow and discharge operations are not made, it is to process the harmful gas remaining untreated by the purge device 300 of the present invention.

In the same manner as described above, when the direction of the inflow hole 122 and the discharge hole 111 and 121 is changed by the rotation of the rotor 100, the partition 200 in which the purge operation is performed is provided with a symmetrical form on the opposite side 300. ) Causes purge operation and blows up residual harmful gas into combustion chamber.

As described above, the purge device 300 which is provided symmetrically on the lower side alternately operates with the harmful gas that is discharged from the discharge holes 111 and 121 anyway. It is because it does not need to blow up into the upper combustion chamber 2 because it is mixed.

As shown, the purge device 300 is equipped with a purge pipe line 310 on both sides of the bottom of the partition wall 200, each of the purge pipe line 310 is provided with a damper (320).

Each purge blower 330 continuously blows into each of the purge pipes 310, and the dampers 320 are sequentially opened so that noxious gas and clean air remaining inside the partition wall 200 are burned in the combustion chamber 2. It is blown up and burned again to clean air.

The damper 320 is opened and closed by an opening / closing cylinder 321 provided at one side, and as described above, the discharge holes 111 and 121 and the inlet hole 122 are covered by the purge plates 220 and 230 so that noxious gas and clean air are provided. When the flow is cut off for a while, the opening and closing cylinder 321 of the partition 200 is cut by the electrical signal of the sensing means (not shown) operates to open the damper 320.

On the other hand, when the electrical means is input to the controller (not shown) of the sensing means (not shown), each of the opening and closing cylinders 321 is sequentially operated from 1 to 6 times of each partition 200 It purges harmful gas and clean air remaining inside.

The sensing means can be easily modified by any number, such as a photo sensor, a limit switch, a timer switch, or a timer as a manufacturing technology in the art.

In addition, the other end of the inner tube 110 of the rotor 100 is continuously connected to the drive unit 400, the rotor 100 of the present invention is rotated at a low speed of 3 ~ 4 RPM / Min and the heat storage layer (3) It is to purify the harmful gas by repeating the inflow and discharge as described above.

On the other hand, it has been described that the harmful gas is supplied to both sides by the first and second blowers (101, 102) provided at both ends of the inner tube 110 described above, the manufacturing method of the art, the inner tube (110) Only one blower may be provided at either the leading edge or the trailing edge of In other words, if the capacity of the blower is increased, the flow rate of the noxious gas that is supplied from both ends can be obtained.

4 to 6 will be described in detail the operation of each of the above-described configuration of the present invention.

As shown, the noxious gas supplied by the first and second blowers (not shown) to the inner tube 110 of the rotor 100 passes through the discharge holes 111 and 121 and passes through the upper heat storage layer 3 to the combustion chamber ( In 2), noxious gas is removed by the heat of combustion of the burner 2a.

On the other hand, clean air in which noxious gas is burned in the combustion chamber (2) moves downward again through the heat storage layer (3). When clean air passing through the heat storage layer (3) is burned in the combustion chamber (2), approximately When the temperature rises to about 750 ~ 850 degrees to burn the harmful gas is discharged to the clean air, the temperature of the heat storage layer (3) is heated by the rotation of the rotor 100 of the present invention when the harmful gas passes through the heat storage layer (3), Firstly, the temperature is increased and the combustion is easily performed in the combustion chamber 2, so that the fuel burner may be saved by intermittently operating instead of continuously operating the combustion burner.

The clean air flows into the inflow hole 122 formed in the exterior 120 of the rotor 100 and is discharged to both ends of the exterior 120.

As shown in FIG. 6, the inlet hole 122 and the outlet hole 111 and 121 formed in the rotor 100 are covered by the purge plates 220 and 230 so that harmful gas in which the inlet and the outlet are repeated is present in the partition 200. Remaining, the position of the inlet 122 and the discharge hole (111, 121) is changed to the combustion is complete and the lower purge device to prevent the newly introduced clean air and residual harmful gas to be discharged into the atmosphere By 300, the harmful gas remaining in the partition 200 is returned to the combustion chamber.

At this time, the partition 200 of the other compartment is a normal inlet and discharge of the harmful gas and clean air is made, the purge device when the discharge hole (111, 121) and the inlet hole 122 is covered by the purge plate (220,230), The purge operation is performed by 300.

When the purge of the noxious gas remaining inside the partition wall 200 is completed by the purge device 300, and the discharge holes 111 and 121 and the inlet hole 122 are out of the purge plates 220 and 230, the noxious gas is normally discharged. Supplying to the heat storage layer (3), the clean air is repeated through the inlet hole 122 discharged to both ends of the exterior (120).

As described above, the first and sixth partition walls 200 are sequentially repeated. In other words, when the purge of the first partition wall is completed in the purge plates 220 and 230, the second partition wall is purged, and the third to six times are repeatedly purged sequentially, so that the heat storage layer 3 By raising the temperature so as to keep the temperature constant, the temperature of the combustion chamber 2 can be maintained at a high temperature even if the burner 2a of the combustion chamber 2 is not continuously operated.

In addition, although the partition wall 200 has been described as being formed into six compartments, it may be increased or decreased according to the size and required throughput of the facility.

7 and 8 illustrate another embodiment of the rotor 10 of the present invention, wherein the second discharge hole 121 and the inlet hole 122 formed in the exterior 120 of the rotor 100 are shown. Excessive wind pressure acts on any part of the rectifying plate 130 having a plurality of perforations formed therein, and the harmful gas flowing through the second discharge hole 121 and the clean air flowing through the inlet hole 122 act on one part. To prevent a stable flow.

In other words, when the fluid of the noxious gas and the clean air passes through a plurality of perforations of the rectifying plate 130, the flow rate is reduced to achieve a stable flow as a whole.

The rectifying plate 130 is mounted so as not to protrude from the outer circumference of the second discharge hole 121 and the inlet hole 122 described above, and when the rotor 100 rotates, the first and second purge plates 220 described above. ) So that interference with the inner circumference of the 230 is not generated.

The present invention is not limited to the above-mentioned specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Such modifications are within the scope of the claims.

As described above, according to the present invention, by introducing and purging clean air discharged into the atmosphere to prevent mixing of harmful gas and clean air, there is an effect of preventing the harmful gas from being mixed with clean air.
