Problems solved by technology

However, this "sewage source heat pump self-cleaning heat exchanger" inevitably has some shortcomings due to structural limitations, such as: the long shape brings a lot of inconvenience to transportation and installation into the system; The heat exchange efficiency of the straight tube heat exchange tube is relatively low; in addition, the disassembly of the heat exchanger is not very convenient, etc.

Embodiment 1

[0017] Embodiment one, as shown in Figure 1:

[0018] The present invention includes a casing 1 and a heat exchange tube 2 running through it, and a circulation channel 11 for a heated medium is formed between the inner wall of the casing and the outer wall of the heat exchange tube. An inlet port 12 and an outlet port 13 for the heated medium are provided on the tube wall of the outer casing; a pitch type chain shaft descaler 3 is arranged axially in the heat exchange tube. Connecting joints 21 and glands 22 are provided between both ends of the casing 1 and the heat exchange tubes. Both ends of the heat exchange tube 2 are provided with a tee joint 23 and an end cover 24, and the radial direction of the tee joint is provided with a sewage inlet port 231 and an outlet port 232 communicating with the inner cavity of the heat exchange tube. The heat exchange tube in the figure is a spiral tube. The heating medium enters from the inlet port 12 of the heating medium, hovers in ...

Embodiment 2

[0019] Embodiment two, as shown in Figure 2:

[0020] The unit pitch of the pitch type chain shaft descaler set in the heat exchange tube of the present invention is cylindrical (polygonal column shape is not shown in the figure), and the two ends of the unit pitch are respectively provided with shoulders 34 and grooves 35, and adjacent units The pitch shoulder is inserted into the groove, and is connected to a chain shaft by a pin shaft 36; the unit pitch is provided with a descaling brush whose bristles are soft steel wires. The descaling brush can also be made of plastic wire or livestock hair, and the radial dimension is adapted to the internal diameter of the heat exchange tube.

[0021] Preferred embodiment, as shown in Figure 3:

[0022] In this embodiment, one end of the pitch type chain shaft descaler 3 is connected to the driven ring 371 of the overrunning clutch 37, the driving wheel shaft 372 of the overrunning clutch forms a rotary seal with the end cover 24, and...

Abstract

The invention relates to a sewage source heat exchanger, which comprises a sleeve and a heat exchange tube which passes through the sleeve axially. A part connector joint and a gland bush are arranged between both ends of the sleeve and the heat exchange tube and the inlet and outlet interfaces of a heated medium are arranged on the wall of the sleeve; the two end parts of the heat exchange tube extending out of the sleeve are provided with a tee coupling and an end cover, the tee coupling is radially provided with sewage inlet and outlet interfaces communicated with the inner cavity of the heat exchange tube; the heat exchange tube is internally provided with a pitch chain axle scale-borer. The sewage source heat exchanger not only can be made into a straight tube, but also can be designed into bending ring structure like a U shape, an O shape, an S shape, and the like. In the precondition of achieving the same heat exchange effect, the invention shortens the length of the heat exchange tube, reduces the mounting space of the heat exchanger, and decreases material consumption and production cost; the invention can actively control the continuous or regular decontamination and thedecontamination in different rotation directions on the heat exchanger, with good decontamination effect; and the heat exchanger can be conveniently disassembled and easily cleaned. The heat exchanger is especially suitable to be used as a condenser or an evaporator in a sewage source heat pump system.

Description

technical field [0001] The invention relates to heat exchanger technology, in particular to a heat exchanger using raw sewage as a heat source. Background technique [0002] At present, the application prospect of heat exchangers with obvious energy saving effect and good environmental protection benefits is very good. However, the heat exchangers that are currently on the market are not suitable for heat exchange using unnatural water such as urban raw sewage and industrial waste water as heat sources. This is because raw sewage contains a lot of solid waste and high sediment content, and the sediment cannot flow synchronously with the water, and the resulting sediment will cause pipeline blockage; in addition, the combination of various organic matters and sludge contained in it is very serious. It is easy to form "soft scale" attached to the inner surface of the heat exchanger, which will seriously affect the heat exchange effect. However, raw sewage or industrial waste...
