Description

FAN COMBINATION CONTROL SYSTEM TYPE WASTE COLLECTION PLANT}

The present invention relates to a waste collection facility for transporting and collecting the waste put into the tube to the suction air flow, in particular the waste collected by raising the air flow in the tube with a suction fan while managing the transport line for food waste and the transport line for general waste In the collection facility, the present invention relates to a mixed waste collection facility which can ensure the waste collection in the pipe without any residual even if the length of the conveying line embedded in the ground is greatly extended.

Conventional suction type garbage collection facility is a facility that dumps garbage bags into the inlet provided in the building and is led to the transportation line through the garbage collection line, where the suctioned air is sent to the collection station for batch processing. It is developing into a structure that can integrate and manage food waste derived from and general waste that can be incinerated.

In other words, the food waste collection line and the general waste collection line are separately installed, but recently, they are installed only in the collection pipe inside the building so that food waste and general waste are not mixed, and the pipe changeover device is located at the end of the transport pipe that leads the waste to the treatment facility. In the food waste discharging time zone, the end of the conveying pipe is communicated with the food separator, and in the general waste discharging time, the end of the conveying pipe is connected with the centrifugal separator. The ends are communicated with the pig receiver, so that the pigs that have been cleaned and returned can be collected.

In this way, the integrated management of food waste and general waste can provide the advantages of efficient inspection, operation, and operation.However, if food waste remains inside the transport pipe, the surface of the general garbage bag to be collected later is Cause food waste to come out.

The cause of this problem is the appearance of the total extension length of the delivery line.

In other words, the reference flow rate of the suction air flow generated in the transport pipe buried in the ground is 25m / s, when the total length of the transport pipe is less than 1.9Km can be obtained even when using the inner diameter 500mm pipe, If the length is longer than 2Km, the air pressure in the pipe is lowered and the reference flow rate cannot be obtained.

In general, a tubular body having a total length of 2Km or more and a diameter of 600 mm and a blower having an enhanced capacity are adopted, and at least one air suction valve is provided in the middle of the conveying pipe so that sufficient outside air can be sucked into the 600 mm pipe.

However, since the inner diameter of the pipe 500mm and 600mm has a big difference in terms of construction cost, the construction cost naturally increases.

In addition, due to the compressibility of the air, flow rate irregularity occurs at the connection portion between the inner diameter of 500 mm and the 600 mm, resulting in uneven flow rate, and the supply of reactive air due to the change in cross-sectional area of the pipe increases the operating time of the blower. .

In addition, the adjustment of the air flow rate sucked through the air intake valve provided with one or more is difficult to control because of variations.

Accordingly, an object of the present invention is to provide a mixed waste collection facility having a structure in which no waste remains in the transfer pipe without any increase in the inner diameter of the pipe even when the total extension length of the transfer pipe is longer than 2 km.

In accordance with the above-described object, the present invention, in the collection pipe in the pipe cleaning launcher, household waste inlet, household food waste inlet, and air suction inlet sequentially, the end of the collecting pipe is a centrifuge, pig receiver, food separator Connecting the moving end of the conduit switcher to the collection conduit so as to selectively communicate with any one of them, while connecting the centrifugal separator, the pig receiver and the food separator to the first to third fixed ends of the conduit switcher, respectively. In the first to third fixed stage, the centrifuge, the pig receiver, the food separator is connected to the transfer pipe, and the exhaust side of the centrifuge, the pig receiver, the food separator is also connected to the transfer pipe, and the centrifuge Blowing means is connected to the feed line extending to the exhaust side of the pig receiver and the food separator. The air flow is generated inside the collection pipe and the transfer pipe, and a heat exchanger is installed on the exhaust side of the blower to recover the waste heat in the exhaust, and the air exhausted from the heat exchanger is sequentially passed through the deodorizing means and the disinfection means. By doing so, it becomes the structure which discharges purified air to a sterile odor completely outside.

In such a configuration, the impeller of the pressurized fan may be arranged so that the motors are opposed to each other in pairs, and such a structure enables the supply of more abundant airflow / wind pressure to the collecting pipe.

In addition, in the above-described configuration, it is also possible to cause the movable end of the pipeline switching unit to sequentially communicate with any one of the first to third fixed stages at a time difference through a control program.

The present invention having the above-described configuration is capable of supplying sufficient air volume / wind pressure to the inside of the pipeline by a pressurized fan added to the air inlet, so that even when the total length of the pipeline becomes 2 km or more, a pipe having an inner diameter of 500 mm is applied in the same manner as in the prior art. As a result, it can be implemented without increasing the construction cost.

In addition, since there is no need to add an air intake valve throughout the conduit, the inside of the conduit can be a zero-leak system. As a result, the power saving effect and the flow velocity in the conduit can be made uniform by reducing the operating time of the air blowing means. It is effective to simplify control, and the maximum extension length of the pipe can be increased up to 2.5 km.

In addition, since the air is pressurized and supplied with a pressurized fan, the air flow rate in the pipe is improved to 30 Km / s, and garbage is completely collected without remaining in the pipe.

 Next, the present invention provides an energy saving effect because a heat exchanger is installed on the exhaust side of the blowing means to recover and recycle the waste heat contained in the exhaust.

On the other hand, the present invention has the effect of not causing odors, bacterial contamination, etc., because the exhaust by deodorizing and disinfecting the exhaust.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the configuration of the mixed waste collection facility according to the present invention, in the drawing pipe (2) in the pipe cleaning launcher (4), household waste inlet (6), household waste intake ( 8) is provided and the air inlet 10 is installed at the end.

The collection pipes 2 having such a configuration are arranged in parallel in a plurality of floors of each building, but are collected in one passage and communicate with the movable end 120 of the pipeline converter 12.

In addition to the movable stage 120, the pipeline converter 12 includes a first fixed stage 122 leading to the centrifuge 14, a second fixed stage 124 leading to the pig receiver 16, and food having a water separation function. A third fixed end 126 is provided leading to the separator 18.

In practice, the above-described channel converter 12 includes a structure in which the movable end 120 therein is rotationally driven by a suitable hydraulic mechanism, and thus the movable end 120 has a first to third fixed end. (122) 124, 126 can be connected to either.

In addition, the selective connection between the movable stage 120 and the first to third fixed stages 122, 124 and 126 may be automatically performed at a time difference by a program or may be performed according to a command of a control room.

Next, the first to third fixed stages 122, 124, 126 are connected to each other via the transfer pipe 20 to the centrifuge 14, the pig receiver 16, and the food separator 18, respectively. In addition, the exhaust side of the centrifuge 14, the pig receiver 16, and the food separator 18 are also gathered together through the transfer pipe 20 and connected to the blower means 22, respectively.

The exhaust side of the blowing means 22 is opened to the atmosphere via the air filter 24, the heat exchanger 26, the deodorizing means 28, and the disinfection means 30.

In the mixed waste collection facility related to the present invention, the air inlet 10 includes a pressurized fan 100.

2, the air inlet 10 having the rain hood 102 covered with the mesh 104 mounted on the inlet is connected to and connected to the duct 108 via the expansion tube 106. The fan 100 is disposed in such a manner that the impeller 110 is positioned at the side of the duct 108 so that the impeller 110 is rotated by an external motor 112 to pump air into the collecting pipe 2.

Reference numeral 114 in the drawing is an inspection window.

The pressurizing fan 100 having the above-described configuration is effectively used when the length between the channel converter 12 and the blowing means 22 is extended to 2 Km or more.

That is, since the impeller 110 of the pressure fan 100 sucks external air through the air suction port 10 and sends it to the inside of the collection pipe 2, the internal air volume / wind pressure of the collection pipe 2 is in a supercharged state. At this time, the internal air in the supercharged state is collectively collected waste while generating a substantial air flow under the action of the negative pressure caused by the operation of the blowing means 22, in the process, the pressurized fan 100 continues to have a sufficient amount of air It is completely collected without waste because of the wind pressure.

On the other hand, the blowing means 22 generates negative pressure without distinguishing when pigs are introduced into the collecting pipe 2 through the pigtailer 4, when collecting general garbage bags, or when collecting food waste, Accordingly, the air flow started from the inside of the collecting pipe 2 is exhausted while the pigs are filtered through the pig receiver 16 when the pigs are put in, and in the case of collecting the general garbage bags, the garbage bags are turned over by the centrifuge 14. When the food waste is collected, the food waste is discharged while taking over the food collected by the food separator 18.

The air flow exhausted as described above passes through the air blowing means 22 through the conveying pipe 20, and removes the mixed dust, etc. while passing through the air filter 24, and then recovers waste heat while passing through the heat exchanger 26 After passing through the deodorizing means 28 and the disinfection means 30 sequentially, it is discharged into the atmosphere as uncontaminated air.

In the present invention, the disinfection means 30 may be suitably used as an ultraviolet sterilizer.

The heat exchanger 26 absorbs and recycles waste heat contained in the exhaust. Any heat exchanger 26 may be suitably employed as long as it efficiently absorbs and transfers cold and warm air, such as a sensible heat exchanger.

In addition, in the present invention, the pressurizing fan 100 is not limited to the configuration of FIG. 2, but may also be implemented in a configuration in which the motor 112 is arranged in pairs to face each other, as illustrated in FIG. 3. A larger air volume / wind pressure can be acted into the interior of 20).
