Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the heat exchange effect of the existing waste water heat recovery device is poor, and the heat exchange efficiency is affected after the sediment is not cleaned up, and even the pipeline is blocked. The waste water heat recovery device adopts the principle of convection to improve the heat exchange efficiency, and adopts the bellows to increase the heat exchange area, and cleans the outer wall of the heat exchange tube by disturbing the water flow, so as to reduce the deposition of dirt and prevent the blockage of the pipe

Embodiment 1

[0025] Such as figure 1 As shown, the wastewater heat recovery device with anti-blocking function includes the heat recovery bellows 2 installed in the sewage pipe 1, which adopts the countercurrent method to improve the heat exchange efficiency, so the water flow direction in the heat recovery bellows 2 and The direction of water flow in the sewage pipe 1 is opposite, and at the same time, the two ends of the heat recovery bellows 2 are respectively close to the two ends of the sewage pipe 1, which not only realizes maximum contact, but also reduces heat waste. The two ends of the sewage pipe 1 are respectively named as the waste water inlet 4 and the waste water outlet 5 according to the direction in which the waste water 8 enters and exits, and the two ends of the heat recovery bellows 2 are respectively named as the cold water inlet 6 and Warm water outlet 7, according to the pipe layout method of heat recovery cold water and waste hot water, the cold water inlet 6 is at t...

Embodiment 2

[0027] Such as figure 2 , image 3As shown, on the basis of Example 1, the heat recovery bellows 2 made of thin-walled stainless steel is formed into a spiral structure, and the spiral structure is coaxial with the sewage pipe 1. In the spiral structure formed by the heat recovery bellows 2 There are gaps between the outer walls of adjacent bellows rings. The heat recovery corrugated pipe 2 will automatically form a certain elastic stress when it is formed into a spiral shape. This stress can make the heat recovery corrugated pipe 2 close to the inner wall of the sewage pipe 1, making it difficult to move. When the heat recovery corrugated pipe 2 is formed into a spiral pipe The elastic stress will also make each ring of bellows form a certain fixed gap. The gap allows the heat recovery bellows 2 to exchange heat with the sewage pipe 1 to form an effective spiral guide for the waste hot water in the sewage pipe, and strengthen the heat exchange between the waste water and t...

Embodiment 3

[0029] Such as Figure 4 , Figure 5 As shown, on the basis of the above-mentioned embodiments, a cleaning device for flushing the outer wall of the heat recovery bellows 2 is provided under the heat recovery bellows 2 and in the sewage pipe 1. In consideration of cost and cleaning convenience, high pressure is preferred. The way of air injection, so the cleaning device includes a compressed air pipe 3, on which several nozzles 9 are arranged, and the nozzles 9 are arranged symmetrically along the axis of the compressed air pipe 3, and the sprayed area of ​​all nozzles 9 can cover the entire Root heat recovery bellows 2. The compressed air nozzle 9 is used for manual or automatic air injection, which can promptly and effectively clean the dirt on the wall of the heat recovery bellows 2, so that the heat recovery device can operate efficiently for a long time. The jet of air through the nozzle 9 can effectively disturb the waste hot water 8 in the sewage pipe, form a strong e...

Abstract

The invention discloses a waste hydrothermal recycler with an anti-blocking function and a using method thereof. The waste hydrothermal recycler comprises a thermal recycling corrugated pipe installed in a sewage pipe. The direction of a water flow in the thermal recycling corrugated pipe is opposite to the direction of a water flow in the sewage pipe, and a cleaning device used for flushing the outer wall of the thermal recycling corrugated pipe is arranged in the sewage pipe. According to the waste hydrothermal recycler with the anti-blocking function and the using method thereof, the thin-wall stainless steel corrugated pipe is adopted, and the corrugated pipe is coiled to be in a spiral shape to enable waste hot water to flow from the middle and the periphery of the spiral coiled pipe so that all the positions of the whole spiral corrugated coiled pipe can effectively exchange heat; by adopting a pipe-arranging mode of cold water thermal-recycling and waste hot water reverse-flowing, the using effect of the thermal recycler is greatly improved, the warm-water outlet temperature of the thermal recycler is effectively improved, and the discharging temperature of the waste hot water is greatly reduced; and a compressed air pipe is designed below the corrugated spiral pipe and in the sewage pipe, long-term stable heat-exchanging of the thermal recycling corrugated pipe is greatly guaranteed, and the whole thermal recycler is prevented from being blocked by dirt.

Description

technical field [0001] The invention relates to a heat recovery tool, in particular to a waste water heat recovery device with an anti-blocking function and a use method thereof. Background technique [0002] In daily life, hot water is used for showering and hair washing, and the waste water generated after showering and hair washing is directly discharged into the sewer, causing a lot of waste heat waste. In the industry, some waste water containing heat waste water is directly discharged. The temperature of waste water or industrial waste water is roughly 30°C to 50°C, and its direct discharge causes a waste of energy and is not conducive to environmental protection, especially for places with a large amount of hot water such as industries and bathing centers. To reduce costs, people have designed waste water heat recovery devices to recover the heat in these waste waters. Traditional waste water heat recovery devices mostly use an immersion structure, which has poor heat...
