DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to components which should not be discharged to the atmosphere as they are, such as odorous or harmful components such as odorous gas, volatile organic compounds (VOC), dioxins and furans (hereinafter referred to as "processed"). Component) is introduced into the heating layer, and in a high-temperature atmosphere in the heating layer, the component to be treated is rendered harmless by, for example, oxidative decomposition. More particularly, the present invention relates to a regenerative fluid processing apparatus.

[0002]

2. Description of the Related Art As a thermal storage type fluid processing apparatus as described above, the one shown in FIG.
No. 141407). In FIG. 12, a pair of heat storage layers 2 (2a, 2b) in which a processing gas can flow freely and can exchange heat with the flowing processing gas are provided in a processing layer 1 surrounded by a heat insulating material. Between the pair of heat storage layers 2a and 2b, there is provided a heating layer 4 which is heated by a heating means (a burner having a flame port) 3 and through which a processing gas passes. When the processing gas passes through, the detoxification processing by oxidative decomposition of the component to be processed contained in the processing gas is performed.

At both ends of the treatment layer 1, a first flow path 5a faces one heat storage layer 2a and a second flow path faces the other heat storage layer 2b. 5b are arranged. The processing gas flowing into the first flow path 5a passes through the heat storage layer 2a (usually in a heat storage state) as shown by a solid arrow in FIG. Then, the component to be treated is subjected to oxidative decomposition treatment, and the treated gas after the treatment passes through the other heat storage layer 2b in a non-heat storage state, flows into the second flow path 5b, and is discharged therefrom to the atmosphere. . The processing gas after passing through the heating layer 4 is in a high temperature state, and heat is stored in the heat storage layer 2b when passing through the heat storage layer 2b. After the processing for a predetermined time has progressed, the flow direction of the processing gas is reversed, and the processing gas flows from the second flow path 5b into the heat storage layer 2b in the heat storage state, as indicated by the phantom arrow in FIG. After being subjected to the oxidative decomposition treatment of the component to be treated in the heating layer 4, the treated gas after treatment is radiated by the previous passage of the treatment gas, passes through the heat storage layer 2a in the non-heat storage state, and flows through the first stream. It flows into the road 5a and is discharged there to the atmosphere. Hereinafter, this inversion is repeated.

In order to periodically reverse the flow of the processing gas, a first port 6a, a second port 6b, a third port 6c
And a four-way valve 6 having a fourth port 6d. FIG.
At the position of the valve 7 indicated by the solid line in the above, the processing gas flowing from the pipe 8 into the first port 6a flows from the second port 6b through the pipe 9a into the first flow path 5a. After receiving the above-described processing, the flowing processing gas reaches the second flow path 5b, from which it flows into the third port 6c via the pipe 9b,
The air is discharged from the fourth port 6d through the pipe 9c to the atmosphere (flow in the direction of the arrow shown by the solid line in FIG. 8; hereinafter, this is referred to as a first communication state).

After a predetermined time has elapsed, the valve 7 of the four-way valve 6 is switched to the position indicated by the phantom line in FIG. 12 by a signal from a control device (not shown). As a result, the first port 6
a flows into the pipe 9b from the third port 6c.
, Flows into the second flow path 5b, and after receiving the above-described processing, reaches the first flow path 5a. From there, it flows into the first port 6b through the pipe 9a, and from the fourth port 6d, the pipe 9
c and is released to the atmosphere (flow in the direction of the arrow indicated by the phantom line in FIG. 12; this is hereinafter referred to as a second communication state).

In the regenerative fluid processing apparatus having the above-described flow direction switching means, the processing gas is switched from the first communication state (second communication state) to the second communication state (first communication state). When the flow direction is switched, the processing gas located in the pipe 9a (pipe 9b), the first flow path 5a (the second flow path 5b), and the heat storage layer 2a (the heat storage layer 2b) immediately before the switching is performed. Immediately after switching, the four-way valve 6 is connected to the second port 6b (third port 6c) without passing through the heating layer 4.
It is possible that the gas flows backward and flows through the pipe 9c from the fourth port 6d and is released to the atmosphere. In that case, the component to be treated is released to the atmosphere without any treatment.

In order to avoid such a situation, purging heat transfer tubes 10 a and 10 b passing through the heating layer 4 are provided, and
The branch pipe 9d is connected to the purge heat transfer tubes 10a and 10b, and the on-off valve 11a and the branch pipe 9d provided downstream of the branch position of the pipe 9c and the purge heat transfer tube 1 are connected to each other.
By appropriately controlling the on-off valves 11b and 11c provided between the first and second valves 0a and 10b by a controller (not shown), the processing gas which cannot pass through the heating layer 4 when the flow direction of the processing gas is switched is purged. Heat transfer tube 10
a, or 10b, where
The components to be treated are oxidatively decomposed.

[0008]

In the regenerative fluid processing apparatus of the above-described embodiment, the four-way valve 6 and many pipes connecting the four-way valve 6 to the processing layer 1 are used for switching the flow direction of the processing gas. Since the roads (9a to 9d) are required, the related incidental facilities become large and must be heavy. Further, since a large pressure loss is caused by the pipeline, a large output is required for sending the processing gas, and the maintenance cost is increased. Also, since many pipelines are required, it is not easy to modularize (unitize), and when the amount of gas to be treated increases or decreases from the initial plan, it is appropriate It is difficult to deal with.

Further, structurally, the processing gas flows in one flow path (the first flow path 5a or the second flow path 5b) between the first communication state and the second communication state. Therefore, the flow direction must be changed in the forward direction and the reverse direction (for example, the solid line direction and the imaginary line direction in the figure), so that a processing gas that cannot pass through the heating layer when the flow direction is switched is generated. For the treatment, the heat transfer tubes for purging 10a,
It is necessary to provide some kind of heat treatment section such as 10b.

An object of the present invention is to eliminate the above-mentioned disadvantages of the currently used regenerative fluid treatment apparatus, and more specifically, to simplify the structure and reduce the weight and size. Another object of the present invention is to provide a regenerative fluid processing apparatus capable of reducing pressure loss when a processing fluid passes through the inside of the apparatus, thereby reducing manufacturing costs and maintenance costs.

Another object is modularization (unitization).
When the amount of gas to be treated increases or decreases from the initial plan,
An object of the present invention is to provide a regenerative fluid treatment apparatus that can easily and appropriately deal with the above problem. Still another object is to prevent the untreated fluid from being discharged when the flow direction is switched. Therefore, it is not necessary to provide a separate heat treatment unit as in the conventional apparatus, and the structure is reduced. An object of the present invention is to provide a regenerative fluid processing apparatus which can be simplified and manufactured at low cost.

[0012]

According to the present invention, there is provided a regenerative fluid treatment apparatus comprising: a treatment layer including a pair of heat storage layers and a heating layer sandwiched between the pair of heat storage layers; A first flow path facing one side, and a second flow path facing the other side of the heat storage layer, and the unprocessed fluid sent into one of the flow paths is the processing layer. , Undergoes a required process by passing through, and flows into and out of the other flow path, and the sending flow path alternates with the first flow path and the second flow path. In the regenerative fluid processing apparatus that can be switched to, the inflow-side flow path selecting means for selectively feeding the unprocessed fluid to the first or second flow path on the upstream side, and the inflow-side flow path selection means on the downstream side Outlet-side flow path selecting means for selectively discharging a treated fluid from the first or second flow path And by selectively switching between the inflow-side flow path selection means and the outflow-side flow path selection means, the flow direction of the unprocessed fluid and the processed fluid in the first and second flow paths is constantly changed. It is characterized in that the fluid to be treated can be continuously processed in the same direction.

In the present invention, preferably, the inflow-side flow path selection means includes an opening / closing member disposed on the inlet side of the first and second flow paths, and the outflow-side flow path selection means includes An opening and closing member is provided on the outlet side of the first and second flow paths. As each of the opening and closing members, any opening and closing means such as an opening and closing damper, a sliding opening and closing member, and a rotating opening and closing member can be used independently as long as they can temporarily block and open the flow of the fluid. Or in combination. Preferably, the opening / closing member arranged on the entrance side of the first and second flow paths and the opening / closing member arranged on the exit side of the first and second flow paths both open one flow path and open the other flow path. The operation of opening the flow path is performed as an interlocked operation.

In the thermal storage type fluid treatment apparatus according to the present invention, the upstream side of one of the flow paths is opened and the downstream side thereof is closed by operating the inflow side flow path selecting means and the outflow side flow path selecting means.
By operating with the upstream side closed and the downstream side open in the other flow path, all of the fluid to be processed flowing from one of the flow paths passes through the processing layer, where the required processing (for example, oxidation of the component to be processed) is performed. (Decomposition treatment), and thereafter, it moves to the other flow path and is released into the atmosphere. By operating the inflow-side flow path selection means and the outflow-side flow path selection means to operate the opening / closing mode in a manner opposite to the above, the flow direction of the fluid in the flow path does not change, and the treatment layer is formed. The flow direction of the passing fluid is reversed.

That is, in the regenerative fluid processing apparatus according to the present invention, the flow direction of the processing fluid passing through the processing layer is reversed simply by switching the inflow-side flow path selection means and the outflow-side flow path selection means. And the flow direction of the fluid in the first and second flow paths is the same even if the flow direction changes. This indicates that it is possible to continuously and alternately process fluids without providing a flow path switching valve such as a four-way valve or a complicated pipeline system, and is lighter and more lightweight than conventional devices. Not only the size is reduced, but also the pressure loss is reduced, and the cost of the entire apparatus can be reduced. Also, the installation of the apparatus can be improved.

[0016] In a preferred embodiment, the first and the second are used.
Each of the flow paths is normally open, but is further provided with an intermediate flow path selecting means that can close the flow path to shut off the flow of the processing fluid flowing therethrough. As the intermediate flow path selecting means, an arbitrary opening / closing means such as an open / close damper, a slide-type open / close member, a rotary open / close member, or the like is used. In this aspect, at the time of the switching operation of the inflow-side flow path selection means and the outflow-side flow path selection means, by incorporating an operation of temporarily closing the intermediate flow path selection means, the flow path initially the inflow side All of the untreated fluid present can be released to the atmosphere after passing through the treatment layer. This means that the untreated fluid can be completely prevented from being released to the atmosphere during switching, without special heating means as in the case of conventional devices, whereby the device is It is greatly simplified.

In a preferred embodiment, the heating layer has a heat source therein, and the heat source may be a flame from a burner, and has no flame or emits a flame into the heating layer. It may be. In the latter case, since the flame does not come into direct contact with the processing fluid, even if incomplete combustion occurs for some reason, it is possible to prevent the generated contaminants from being mixed into the processed fluid.

In a preferred embodiment, the regenerative fluid treatment apparatus of the present invention is configured as a box-shaped module having a rectangular cross section as a whole. This is easily achievable because the apparatus of the present invention does not require a complicated piping system and the processing fluid always flows in the same direction, and since the apparatus can be modularized, handling of the entire apparatus becomes extremely easy. . Moreover, since it is comprised as a box-shaped module, it becomes easy to arrange | position two or more said thermal storage type fluid processing apparatuses in parallel, and to assemble as a thermal storage type fluid processing system. This means that even if the amount of the processing gas to be processed increases or decreases from the initial plan, it can be properly dealt with simply by increasing or decreasing the number of regenerative fluid processing units as modules. It is very useful in practice.

In the present invention, the fluid to be treated is a gas containing harmful components such as volatile organic compounds, dioxins, and furans as components to be treated, or a gas containing various off-flavor components such as ammonia and aldehyde. It is. The treatment layer may be a layer that renders the harmful component or off-flavor component harmless by heat treatment (for example, oxidation treatment), or a layer that has a catalyst and renders the harmful component or off-flavor component harmless by decomposition treatment using a catalyst. It may be.

The first outflow-side opening / closing damper D5 and the second outflow-side opening / closing damper D6 are used as the "outflow-side flow path for selectively discharging the treated fluid from the first or second flow path.""Means for selecting". Further, at a substantially intermediate position in the fluid flow direction of the first flow path 50a,
A similar damper is mounted as a first intermediate opening / closing damper D3, and a similar second intermediate opening / closing damper D4 is also mounted at a substantially intermediate position in the fluid flow direction of the second flow path 50b. The first intermediate opening / closing damper D3 and the second intermediate opening / closing damper D4 are examples of the "intermediate flow path selecting means" in the present invention.

Each of the opening / closing dampers D1 to D6 can be of any shape as long as it can open and close the flow path. For example, as shown in FIG. 1 as D2 and D5, the fins are closed. Can substantially block the flow of fluid in the flow path, and can pass the fluid without substantial pressure loss when the fins are open, as shown as D1 and D6. It is desirable that
The opening and closing of each of the opening and closing dampers D1 to D6 is individually controlled by a control device (not shown). As shown in FIG. 1, the thermal storage type fluid processing apparatus 50 is configured as an independent module as a whole, and can be transported alone or assembled at an arbitrary place.

Next, the operation of the thermal storage type fluid processing apparatus 50 will be described. FIG. 2 illustrates a procedure for switching the flow path of the processing fluid during the operation of the regenerative fluid processing apparatus 50, and FIG. 3 illustrates an example of an opening / closing time chart of each of the opening / closing dampers D1 to D6. In FIG. 2A, the first flow path 5
0a, the first inflow opening / closing damper D1 is opened, the first outflow opening / closing damper D5 is closed, while the second inflow opening / closing damper D2 of the second flow path 50b is closed, and the second outflow. The side opening / closing damper D6 is open. The first intermediate opening / closing damper D3 and the second intermediate opening / closing damper D4 are both open.

In this state, the processing fluid flows from the first inflow-side opening / closing damper D1 into the first flow path 50a,
From the entire area of the heat storage layer 20a facing the flow path 50a, and flows into the heating layer 40 through the heat storage layer 20a. The space in the heating layer 40 is set to a high temperature field by the combustion of the burner 31,
The components to be processed contained in the processing fluid are detoxified (deodorized) by undergoing a process such as oxidative decomposition, and the temperature of the processing fluid also increases. The processing fluid after the high temperature processing is stored in the heat storage layer 20.

Ob is discharged to the atmosphere through a second outflow-side opening / closing damper D6 located downstream of Ob. In the process, the heat storage layer 20b stores heat.

After a lapse of a predetermined time, the flow path is switched. At this time, the first inflow-side opening / closing damper D1 is closed, and the second inflow-side opening / closing damper D2 is opened. At the same time, the second intermediate opening / closing damper D4 located in the second flow path 50b is closed, and the state shown in FIG. In this state, the unprocessed fluid is confined in the first flow path 50a by closing the first inflow-side opening / closing damper D1.

In this state, the processing fluid flows from the second inflow opening / closing damper D2 into the second flow path 50b. However, since the second intermediate opening / closing damper D4 located in the second flow path 50b is closed, the flowing processing fluid flows into the second flow path 50b.
Heat storage layer 20 located upstream of the intermediate opening / closing damper D4 of FIG.
The heat reaches the heating layer 40 after passing through the portion b, and from there passes through the portion of the heat storage layer 20a which is also located upstream of the second intermediate opening / closing damper D4 and flows into the first flow path 50a. As a result, the untreated fluid confined in the first flow path 50a passes through the heat storage layer 20a located downstream of the second intermediate opening / closing damper D4 to reach the heating layer 40,
From there, it passes through the heat storage layer 20b and moves to the second flow path 50b. As a result, required processing for the component to be processed is performed. The processed fluid that has flowed into the second flow path 50b is discharged to the atmosphere through the second outflow opening / closing damper D6.

At the point when the untreated fluid trapped in the first flow path 50a is discharged through the second outflow opening / closing damper D6, as shown in FIG.

This state is a state of steady operation in a state where the flow path is reversed. In this state, the processing fluid is preheated by passing through the heat storage layer 20b in the heat storage state, so that the heating efficiency is improved, and the processed fluid having a high temperature after the heat treatment passes through the heat storage layer 20a on the downstream side. Released into the atmosphere while storing heat.

After the operation for a predetermined time in the state shown in FIG. 2C, the flow path is switched again. That is, the second

a, the second intermediate opening / closing damper D3 located at a
The state shown in FIG. In this state, the unprocessed fluid is confined in the second flow path 50b by closing the second inflow-side opening / closing damper D2.

In this state, the processing fluid flows from the first inflow opening / closing damper D1 into the first flow path 50a, but the second intermediate opening / closing damper D3 located in the first flow path 50a closes. Therefore, the inflowing processing fluid passes through the portion of the heat storage layer 20a located upstream of the first intermediate opening / closing damper D3, reaches the heating layer 40, and from there, also flows from the second intermediate opening / closing damper D3. Thermal storage layer 20b located in the upstream area
It passes through the portion and flows into the second flow path 50b. As a result, the unprocessed fluid confined in the second flow path 50b passes through the heat storage layer 20b located downstream of the first intermediate opening / closing damper D3, reaches the heating layer 40, and from there. It passes through the heat storage layer 20a and moves to the first flow path 50a. As a result, required processing for the component to be processed is performed. The processed fluid that has flowed into the first flow path 50a is
The gas is discharged to the atmosphere through the first outflow opening / closing damper D5.

At the point when the untreated fluid trapped in the second flow path 50b is discharged through the first outlet opening / closing damper D5, as shown in FIG. The outlet-side open / close damper D5 is closed, and the second outlet-side open / close damper D6 is closed.
open. At the same time, the second intermediate opening / closing damper D3 is also opened. This state is a state in which the flow path is reversed again, that is, a normal operation state in which the state returns to the state shown in FIG. Hereinafter, the same repetition is repeated.

FIG. 4 shows a state in which four modular thermal storage fluid treatment devices 50 (50A to 50D) shown in FIG. 1 are arranged in parallel. In the thermal storage type fluid processing apparatus 50 according to the present invention, when the environment changes and the amount of fluid to be processed increases, as shown, the thermal storage type fluid processing apparatus 50 of an appropriate number is easily configured as a system. It is possible to assemble, and prompt response to environmental conservation becomes possible. Also, if the planned throughput can be handled by, for example, three machines, if the system is constructed from the beginning with four machines as shown in the figure, in a steady state, all of the open / close dampers are closed for one machine. It is only necessary to stop operation and operate the remaining three units, and to cope with environmental changes easily and quickly by starting operation of one closed unit even if the amount of fluid to be treated is expected to increase. Can be.
Also, even if the amount of fluid to be treated is expected to decrease,
Appropriate measures can be taken simply by temporarily increasing the number of machines to be closed, and the system can always be operated in an optimal state.

FIGS. 5 to 7 show other examples of the heating means in the heating layer 40. FIG. In FIG. 5, the space width of the heating layer 40 is widened, and the pipe burners 31, 31 on both side positions thereof are arranged in two rows in parallel. By increasing the space width of the heating layer 40 in this manner, the residence time of the component to be treated in the heating layer 40 can be increased, and more complete detoxification processing proceeds. FIG. 6 shows the electric heaters 35 arranged in multiple stages, and FIG. 7b shows the tube burners 36 arranged in multiple stages. In any case, it is easy to make the heating layer 40 a required high temperature field. When an electric heater or a tube burner is used, since the flame does not come into direct contact with the processing fluid, there is an advantage that contaminants generated by incomplete combustion do not mix into the processed fluid.

When the shutter plate 203 is at the position moved to the right end shown in FIGS. 8 and 9, the shutter plate 203 closes the entrance side of the second flow path 150b and opens the entrance side of the first flow path 150a. When the actuator 201 is actuated to move the movable rod 202 in the opposite direction and move it to the left end, the entrance side of the second flow path 150b is opened and the entrance of the first flow path 150a is opened. It is designed to close the side.

The second slide-type shutter device 200A has the same configuration, and an appropriate actuator 201A attached to the upper surface of the outer wall member 101 and a shutter that moves in conjunction with the movement of the movable rod 202A of the actuator 201A. And a plate 203A. Shutter plate 203A
Moves in a direction opposite to that of the first sliding shutter device 200, and when in the position moved to the left end shown in FIG. 8, FIG. 9, and FIG. The outlet side is closed, and the outlet side of the second flow path 150b is opened. As shown in FIG. 11, the actuator 201A is actuated to move the movable bar 202A in the opposite direction so that the shutter plate 2
03A is moved to the right end, the first flow path 15
The outlet side of Oa is opened, and the outlet side of the second flow path 150b is closed. As the actuator, any actuator such as a pneumatic actuator, a hydraulic actuator, or an electromagnetic actuator can be used.

The procedure for switching the flow path of the processing fluid by the first and second slide shutter devices during the operation of the thermal storage type fluid processing apparatus 100 is the same as that described with reference to FIGS. However, in the thermal storage type fluid processing apparatus 100, since the opening / closing means constituting the intermediate flow path selecting means is not provided, the operation procedure related thereto is omitted. Although not shown, the opening / closing means constituting the intermediate flow path selecting means may be provided at an intermediate position between the first flow path 150a and the second flow path 150b. In that case, description will be given based on FIGS. The switching procedure is exactly the same as the procedure performed.
In the thermal storage type fluid processing apparatus 100, the two flow paths can be selectively switched at a time by sliding the shutter plate by the operation of the actuator, so that the configuration is simplified and the operation becomes easy.

[0040]

According to the thermal storage type fluid treatment apparatus of the present invention, the fluid passing through the heat treatment layer can be used without using a complicated piping system and without changing the flow direction of the fluid in the flow path. Since the flow direction can be reversed, the size and weight of the device can be reduced. Thereby, the installation property of the device is greatly improved. Furthermore, since no complicated piping system is required,
The pressure loss when the processing fluid passes through the device is reduced, and the size of the blower fan and the like can be reduced. Thereby, the manufacturing cost and maintenance cost of the device can be reduced. Further, modularization (unitization) is possible, and it is possible to easily and appropriately cope with a case where the amount of processing fluid to be processed increases or decreases from the initial plan.

Further, due to the structure, it is possible to reliably prevent the untreated fluid from being discharged outside the apparatus when the flow direction of the treatment fluid passing through the heat treatment layer is reversed.
