Embodiment Construction
[0030] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0031] Such as figure 1 As shown, inside the waste water heat recovery machine 1, heat exchange plates 2 formed by transversely welding a plurality of square conduits 2a are stacked at certain intervals along the up and down direction, and the center and left and right sides of each heat exchange plate 2 are welded respectively. The short tube 2b of the square conduit 2a is short, so that a waste water drop hole 5 is formed between one side end of the short tube 2b and the partition plate 3 .
[0032] Such as figure 2 As shown, the inlets on both sides of the heat exchange tube 2 are connected to each other through the left and right partitions 3, 3' and connecting parts 4, 4'.
[0033] Such as image 3 and Figure 4 As shown, the left and right partitions 3, 3' are formed with a plurality of through holes 3a, 3a', such as figure 2 and Figure 5 ...

The present invention provides a heat recovery machine of waste water, the heat exchange is processed by ensuring the heating waste water flow in a Z shape from up to down, and ensuring the clean coldwater flow in Z shape from down to up; an air discharge structure such as air discharge hole is formed on the bottom of the heat exchanging plate formed by the square duct welded horizontally which in stacked at an certain interval along the upper and lower direction, the bottom of the heat exchanging plate can not form air layer, so as to improve the heat exchange rate; a reinforced frame is welded on the bottom of the heat exchanging plate at a certain interval, capable of preventing the dropping phenomenon of the heat exchange plate, improving the productive and the durability; a switch plate is formed on the side wall of the body, this not only easily repairs the inner state, but also thoroughly cleans the residual without decompounding the body; an iron reinforced material and heat insulating material are provided in the top and side wall of the body, avoiding the heat loss of the waste water, so as to improve the durability of the heat recovery machine of waste water.
Description
technical field [0001] The invention relates to a waste water heat recovery machine for mutual heat exchange between heated waste water and clean cold water. Background technique [0002] The applicant once proposed in Korean Utility Model Application No. 256619 that the heat exchange plates formed by transverse welding of a plurality of square pipes are piled up and down at certain intervals, so that the heated waste water flows between the heat exchange plates from top to bottom. The bottom flows in a zigzag, and at the same time, the clean cold water flows in a zigzag from the bottom to the top in the square tube of the heat exchange plate, thereby exchanging heat with each other. [0003] The above-mentioned conventional waste water heat recovery machine maximizes the contact area between waste water and clean water in the same body, thus having the advantage of high heat recovery rate of waste water. However, as the use time increases, the heat recovery rate of waste wa...
