Hereinafter, with reference to the accompanying drawings, an embodiment to which the present invention is applied will be described in more detail.

Example 1

As shown in Fig. 1 to Fig. 4, the discharge water (waste water), which is a high temperature heat medium (H), is allowed to pass through the water tank, and the used water (W, cold water) is passed through the heat exchange plate 20 installed in the water tank. In the heat exchanger for recovering, the front fixing plate 10 and the rear fixing plate 30, which is installed on the front and rear of the multiple heat exchange plate 20 to support the heat exchange plate 20, and the front fixing plate 10 and the rear fixing plate Fastening bolt 40 for crimping and fixing the heat exchange plate 20 inserted therebetween, and inserted into upper and lower portions of the front fixing plate 10 and the rear fixing plate 30 for use in disassembly and assembling the heat exchanger. It is made up of the vertical horizontal guide rods 50 and the vertical post 60 to fix the vertical horizontal guide rods 50.

In addition, the front fixing plate 10 and the rear fixing plate 30, polycarbonate (PC), polyethylene (PE), polypropylene (PP), which is a lightweight heat-resistant polymer material in order to reduce heat loss and weight and prevent corrosion Molded and manufactured in the same material, but the outer edge is formed in the U-shaped fastener 15 is opened at a predetermined interval, and the grid and the edge of the front fixing plate 10 and the rear fixing plate 30 exposed to the outside A force 16 is applied to the inlet and outlet 11, 12, 13, and 14 of the heat medium (H) pipe and the water (W) pipe at the upper and lower portions of the front fixing plate 10. It is provided with a connector such as a flange.

The horizontal guide rods 50, which pass through the through holes formed in the middle of the upper and lower ends of the front fixing plate 10 and the rear fixing plate 30, are used at the time of assembling or disassembling the heat exchanger and support the heat exchanger to the vertical column 60. When the heat exchanger is repaired or cleaned inside, the fastening bolt 40 fastened to the outside of the heat exchanger is released and released, and then the rear fixing plate 30 moves the horizontal guide rod 50 so that the heavy heat exchange plate 20 or the rear fixing plate. The operator can easily disassemble the 30. In addition, during assembly, the heat exchanger plates 20 are inserted behind the front fixing plate 10, and the rear fixing plate 30 inserted into the horizontal guide rod 50 is brought into close contact with each other, and then the fastening bolts 40 are fastened to the front fixing plate ( 10) and the U-shaped fastener 15 formed on the rim of the rear fixing plate 30 can be easily assembled by screwing.
