Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The specific embodiment of the utility model provides a heat exchanger, the outside of heat exchanger is provided with

casing

1, 1 inside sewage pipes 2, sleeve pipe 3, collector 4 and the connecting pipe 5 of being provided with of casing, wherein:

as shown in fig. 1 and fig. 2, the sewage pipeline 2 is arranged inside the housing 1, the sewage pipeline 2 is a large-diameter straight pipe, the diameter of the sewage pipeline 1 is increased to a certain extent to avoid blockage, the sleeve 3 is sleeved outside the sewage pipeline 2, sewage passes through the inside of the sewage pipeline 2, a clear water channel 12 is formed between the sewage pipeline 2 and the sleeve 3 to pass through clear water, a heat exchange wall is formed on the pipe wall of the sewage pipeline 2, and the inner wall of the sewage pipeline 2 is a heat exchange surface.

Sewer line 2 can set up to parallel arrangement between a plurality of and a plurality of sewer line 2, and sleeve pipe 3 also sets up to a plurality of and with sewer line 2 one-to-one setting, through multiunit sewer line 2 and sleeve pipe 3's setting, increases the area of heat-transfer surface, improves the work efficiency of heat exchanger.

The two end surfaces of the sewage pipeline 2 are respectively provided with two collecting pipes 4, the collecting pipes 4 are communicated with the plurality of sewage pipelines 2, and the two collecting pipes 4 are respectively provided with a sewage inlet pipe 6 and a sewage discharge pipe 7 for entering and discharging sewage;

the connecting pipes 5 are arranged at two end face positions of the plurality of sleeves 3, the number of the connecting pipes 5 is two, the connecting pipes 5 are communicated with the plurality of sleeves 3, and the two connecting pipes 5 are respectively provided with a water inlet pipe 8 and a water outlet pipe 9 for the entry and the discharge of clean water.

The collecting pipe 4 and the connecting pipe 5 are used for communicating a plurality of sewage pipes 2 or a plurality of sleeves 3, the collecting pipe 4 and the connecting pipe 5 are not communicated, so that the sewage pipes 2 and the sleeves 3 are separated, meanwhile, the collecting pipe 4 can be quickly filled and flows through all the sewage pipes 2, and is discharged by the sewage discharge pipe 6, and the connecting pipe 5 can enable clean water to be filled and flow through all the sleeves 3 and then flow out through the clean water outlet 9.

The positions of the sewage inlet pipe 6, the sewage discharge pipe 7, the water inlet pipe 8 and the water outlet pipe 9 can be as shown in the attached figure 1, wherein the sewage inlet pipe 6 and the sewage discharge pipe 7 are arranged diagonally on the heat exchanger, which is beneficial for discharging sewage through the sewage discharge pipe 7 after the sewage enters the header pipe 4 and then fills up a plurality of sewage pipelines 2, and avoids that sewage flows are directly discharged through the sewage inlet pipe 6 and the sewage pipeline 2 on one side of the sewage discharge pipe 7 when the sewage flows are arranged on the same side;

inlet tube 8 and outlet pipe 9 also are the diagonal angle setting with the same reason, thereby guarantee that the clear water is full of inside whole clear water passageway 12 and connecting pipe 5, fully take place the heat exchange, inlet tube 8 sets up the same one side at sewage pipe 2 and sleeve pipe 3 with blow off pipe 7 simultaneously, it is contrary mutually to make clear water flow direction and sewage flow direction, make sewage and clear water fully take place the heat exchange, if clear water flow direction and sewage flow direction syntropy, probably clear water is the same with sewage flow rate, thereby cause and enter into sewage pipe 2 and clear water passageway 12 inside sewage and clear water when the inside syntropy of pipeline to reach temperature balance fast and thereby only take place very little energy exchange and cause the insufficient problem of energy utilization simultaneously.

The direction that sets up of sewage inlet pipe 6 and blow off pipe 7 can be with sewer pipe 2 syntropy, thereby make the entering of sewage all the same with the sewage flow direction of sewer pipe 2 inside with discharging, when the heat exchanger is clearing up, only need to let in the clear water of high-pressure clear water or add the washing liquid in sewage inlet pipe 6 department, the clear water can wash away the inner wall of collector 4 and sewer pipe 2 fast this moment, then rivers flow through blow off pipe 7, just discharge such as the attached thing on inside filth and the pipe wall very easily with the blow off pipe 7 of rivers syntropy this moment, need not dismantle the washing to the device, thereby realize sewer pipe's clearance and get rid of the filth on the heat-transfer surface and guarantee that heat-transfer surface thermal resistance does not change.

The connecting pipe 5 is arranged perpendicular to the sleeve 3, the collecting pipe 4 is arranged perpendicular to the sewage pipeline 2, the specific shape of the connecting pipe is that the combination of the sewage pipeline 2 and the sleeve 3 is vertically arranged at the bottom of the shell 1, the connecting pipe 5 and the collecting pipe 4 are transversely arranged, the two ends of the combination of the sewage pipeline 2 and the sleeve 3 are arranged, and the connecting pipe 5 can be arranged at the middle position of the combination of the collecting pipe 4, the sewage pipeline 2 and the sleeve 3 through the positions of the connecting pipe 5 and the collecting pipe 4.

Advance dirty pipe 6 and blow off pipe 7 and set up on the lateral wall of casing 1, and run through the lateral wall of casing 1, the terminal surface of advancing dirty pipe 6 and blow off pipe 7 is into dirty mouthful 10 and drain 11 respectively, inlet tube 8 and outlet pipe 9 set up perpendicularly on connecting pipe 5, it is located the outside of casing to advance dirty mouthful 10 and drain 11 and is convenient for the connection of outside pipeline, make the heat exchanger form overall structure simultaneously, only need place the position that needs with whole device when needs are installed, it can use to connect the external pipeline.

It is worth to say that the housing 1 may be a rectangular parallelepiped structure, and may be a container, and the sewage conduit 2, the sleeve 3, the header 4, and the connecting pipe 5 are all disposed inside the container, so that they form a whole, and the installation of the whole device is facilitated.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
