COOLING APPARATUS FOR TRANSFER AIR FLOW IN A DOMESTIC WASTE AUTO-TRANSFERRING TREATMENT EQUIPMENT, AND HEATING SYSTEM USING THE SAME}

The present invention relates to an apparatus and a system for cooling the feed air of the turbo blower installed in the feed pipe line of the automatic automatic waste disposal treatment facility, more specifically to efficiently cool the air flow temperature in the feed pipe connected in series The present invention relates to a turbo blower airflow cooling device and a cooling method of an automatic household waste disposal facility for improving the efficiency of the turbo blower and reducing power consumption of the entire system.

The present invention is derived from the research conducted as part of the Ministry of Knowledge Economy's energy resource technology development project [Task Management Number: 2008-E-CM02-P-03-0, Task name: Development of high efficiency turbo blower for pipeline transportation of domestic waste, Study period: 2008.12.01 ~ 2010.10.31].

In recent years, various environmental improvement projects have been carried out in order to build a pleasant and hygienic living environment. In the treatment of food wastes, automatic waste transportation and transport facilities have been actively constructed by vacuum suction method, mainly in large residential complexes.

Figure 1 is a schematic diagram showing the configuration of the automatic automatic waste treatment processing facility for the automatic collection of waste through the transport pipeline buried underground, Figure 2 is a configuration of a turbo blower installed in the automatic automatic waste treatment facility for domestic waste It is a block diagram for demonstrating schematically.

As shown in Figures 1 and 2, such automatic waste treatment facility for living waste is a method of automatically collecting the waste through the underground buried transport pipeline connected through the inlet or the inside of the building. In other words, it is a facility that automatically transfers food or general waste generated in residential complexes and commercial complexes to the storage by air blowers generated by turbo blowers by using automatic waste disposal facilities.

Such automatic waste disposal facilities for living waste inlet (1) installed inside or outside the building; A transfer pipe (2) connected to the waste inlet (1) and buried in the basement; A centrifuge (3) for separating the food waste conveyed by the transfer pipe (2); A turbo blower (4) installed in the storage box to generate necessary air pressure in the conveying pipe (2); Various dampers and measuring devices (not shown); A filter 5; It comprises a deodorizer 6 and the like.

90% of the energy sources consumed by these automatic waste disposal facilities are turbo blowers 4 installed in a so-called garbage dump (see FIG. 2).

Figure 3 is an example of the configuration of the turbo blower constituting the automatic automatic waste treatment facility, the block diagram showing a series of turbo blower of the ON-OFF start method, Figure 4 is a conventional multi-stage series connection It is a figure which shows the structure of the turbo blower.

As shown in FIG. 3, the common pipe 10 which connects the whole turbo blower 4 is provided, and the suction blower 15 and the discharge pipe 17 are provided in the turbo blower 4 of each stage, respectively. In order to control the flow rate of the cavity tube 10 according to the logarithmic control, a check valve 13 is installed in the cavity tube 10 between the suction tube 15 and the discharge tube 17 to control the airflow. In the case of the flow rate, when the diameter is 500 mm, it is 25 to 29 m / s so that the waste can be smoothly transported in the transfer pipe without clogging.

In such a high pressure multistage series turbocharger, there is a need for a method of reducing a decrease in operating efficiency of a turbo blower due to a temperature rise by air compression of the turbo blower during operation of the multistage series turbocharger.

In general, when the high-pressure air flows into the turbo blower, the air flows from the first stage of the turbo blower in the downstream direction by the air compression of the turbo blower, thereby increasing the inlet air at room temperature by about 100 degrees centigrade. FIG. 5 is a diagram illustrating an actual temperature distribution of a turbo blower system operated by being connected in four stages in series. As can be seen in Figure 5, as the air flow flows from the first stage to the fourth stage, the air temperature gradually rises to about 100 degrees Celsius due to the compression operation of the turbo blower.

As such, when the temperature of the air flowing into the turbo blowers at each stage is increased, the operation efficiency of the rear turbo blowers may be reduced.

Specifically, as shown in FIGS. 6A and 6B, 3-5 turbo blowers (four in FIGS. 6A and 6B) are installed in series to generate a required pressure according to a garbage inlet-collection distance. The required number of turbo blowers is simply operated on and off. As can be seen from the performance characteristics of the four-stage turbo blowers connected to the series in Figure 6b, the air density, temperature and pressure increases as air flows from the first turbo blower to the fourth turbo blower in the rear stage, but the efficiency is the air temperature. It is gradually decreased by the rise of. In addition, the deodorizer or filter installed after the turbo blower tends to decrease the deodorizing effect or the filtering effect as the temperature increases.

In the conventional operation method, the air is compressed and the temperature is increased from the first stage to the downstream stage by simply connecting only the duct on the transfer pipe of the multistage series connection turbo blower installation. As described above, in a conventional turbo blower connection duct system without an air temperature cooling device in a separate duct, a temperature increase due to air compression of the turbo blower cannot be avoided. In addition, in the case of four-stage series turbo blowers, the air temperature at the outlet side exceeds 100 degrees Celsius, and the capacity of the cooler mounted at the inlet of the deodorizer installed downstream of the turbo blower must be increased. There is a problem of wasting.

And, although the waste heat generated in the multi-stage series-connected turbo blower facility has a high energy of more than 100 degrees, there is no way to use it as a separate energy source by simply cooling and removing it.

Therefore, the present invention has been proposed to solve the above problems, it is possible to efficiently cool the airflow temperature in the feed pipe connected in a multi-stage series can improve the operating efficiency of the turbo blower can reduce the power consumption of the entire system It is an object of the present invention to provide a turbo blower airflow cooling device and a cooling method of an automatic household waste disposal facility.

Further objects, features and advantages of the present invention will become more apparent from the following detailed description and the accompanying drawings.

With reference to the accompanying drawings, a turbo blower air flow cooling device and a rapid heating system of the automatic household waste treatment facilities according to the present invention will be described in detail. FIG. 7 is a front view of a turbo blower feed airflow cooling device of an automatic household waste disposal facility, and includes a turbo blower. 8 to 10 is a configuration diagram showing the connection form of the cooling tube connected to the cooling device, Figure 8 shows a cooling coil type, Figure 9 shows a fully connected type, Figure 10 is a view showing a straight pipe internal connection type. FIG. 11 is a cross-sectional view taken along line AA ′ of FIG. 10. It is a figure which shows the cooling device inside the duct of a turbo blower connection part of a main pipe. FIG. 13 is a diagram of a system for performing hot water supply and heating using heat generated by a feed airflow cooling device.

As shown in FIG. 7 and FIG. 8, the cavity tube 20 constituting the turbo blower system for transporting household waste is connected to the suction tube 21 and the discharge tube 23, and the cavity tube 20 is connected to the cavity tube 20. A plurality of turbo blowers 25 connected by connecting pipes 24 are connected. The cavity 20 is provided with a check valve 27 for controlling the air flow.

The common pipe 20 extends the air flow length by being connected to a separate extension pipe 30 extending in the horizontal direction. The inlet of the extension pipe 30 is directly connected to the common pipe 20, the outlet (A, B, C in Fig. 8) of the extension pipe 30 is directly connected to the turbo blower suction pipe (A1, B1, C1 in Fig. 7). Be sure to 9 and 10 in the same manner the extension pipe 30 is connected to the common pipe (20).

And, as shown in Figure 8, the extension pipe 30 is connected to the cooling pipe 40 for cooling the fluid in the extension pipe (30). The cooling pipe 40 is for circulating a refrigerant, such as cooling water, is composed of a closed circuit as a whole.

In addition, a separate circulation pump 50 for circulating the refrigerant inside the cooling tube 40 is connected to the cooling tube 40. In addition, the cooling tube 40 is connected to the cooling unit 60 for maintaining the cooling state of the refrigerant. Therefore, the coolant inside the cooling pipe 40 circulates along the cooling pipe 40, and the temperature is maintained at an average of −10 ° C. to 10 ° C. by the cooling unit 60, thereby allowing the inside of the extension pipe 30 to be cooled. The fluid can be cooled.

The cooling tube 40 may be formed in various forms as shown in FIGS. 8 to 10. First, as shown in FIG. 8, the cooling tube 40 may be formed to spirally surround the outside of the extension tube 30 like a cooling coil. In this case, the extension tube 30 may be formed separately from the cooling tube 40, and the degree of cooling may be adjusted by limiting the number of times the cooling tube 40 is wrapped. In this case, even if the diameter of the extension tube 30 is the same as the diameter of the cavity 20, the loss due to the pressure is negligibly small.

9 and 10 illustrate a state in which the cooling pipe 40 is provided inside the extension pipe 30 together with the cooling fins. The cooling tube 40 may be provided in the entire extension tube 30 as shown in FIG. 9, or may be provided in a portion of the extension tube 30 as shown in FIG. 10.

As shown in FIG. 9 and FIG. 10, the structure in which the cooling tube 40 is provided in the extension tube 30 is illustrated in FIG. 11. As shown, a plurality of cooling tubes 40 may be spaced apart at regular intervals in the extension pipe 30. In this case, due to the cooling tube 40, the movement passage of the air in the extension tube 30 is reduced to increase the pressure loss in the tube at the same flow rate. In order to avoid this point, when the cooling tube 40 is inserted into the extension tube 30, the diameter of the extension tube 30 is increased by the cross section of the cooling tube 40.

12 shows a mixing tube 70 installed in the cavity tube 20 connecting the turbo blowers. As shown, the mixing tube 70 is installed in the cavity tube 20, and has a relatively large diameter compared to the diameter of the cavity tube 20.

In addition, the inside of the mixing tube 70 includes a plurality of cooling passages 41 and a plurality of air passages 43 formed in a plurality of lattice shapes in cross section. The cooling passage 41 is a passage through which the refrigerant moves, and the air passage 43 is a passage of air moving by the turbo blower 25. Therefore, the air moving along the air passage 43 may be cooled by heat exchange with the refrigerant flowing through the cooling passage 41. In addition, the cross section of the cooling passage 41 and the air passage 43 may have a rectangular and pentagonal shape as a basic shape, but may be formed as a circular tube.

The refrigerant passing through the cooling passage 41 in the mixing tube 70 moves through the cooling tube 40 communicating with the cooling passage 41, and the cooling tube 40 includes a circulation pump 50 and The cooling unit 60 is connected. In addition, a plurality of mixing tubes 70 (N ₁ , N ₂ ,... N _n ) may be connected to the cooling tube 40.

13 shows a system for hot water supply and heating using the turbo blower airflow cooling device according to the present invention. As shown, the fluid in the cooling tube 60 having heat by heat exchange with the extension tube 30 exchanges heat with the supply water for hot water supply and heating in the heat exchanger 80. Supply water for hot water supply and heating flows along the supply pipe 100 and provides hot water supply and heating to the supply unit 110 for hot water supply and heating to the outside by using the heat obtained through the heat exchanger 80.

In this way, a cooling device for cooling the hot air generated by the air compression by the turbo blower was installed in the transfer pipe to induce the air temperature to be lowered. The reduction of the turbo blower conveying air greatly contributes not only to the turbo blower high efficiency operation but also to the improvement of the cooler performance in front of the deodorizer installed downstream of the turbo blower.

And, by using a high temperature by the turbo blower to provide hot water and heating to the outside to save energy, it is environmentally friendly.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes within the scope not departing from the technical spirit of the present invention are possible in the art. It will be evident to those who have knowledge of.
