Embodiment Construction

[0020] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0021] Such as figure 1 In the shown embodiment, the sewage source heat pump heat exchange device used in the present invention includes a shell 4 and a spiral chute 1 . The shell 4 is a cylindrical shell, and a sewage chute is arranged spirally inside, which is called the spiral chute 1 herein. Such as Figure 2-4 As shown, the tank body of the spiral chute has an arc-shaped inner groove surface, which is used as a sewage flow channel, and a working medium flow channel 12 is arranged below the inner groove surface. The working medium flow channel shown in the figure is provided in the form of multiple thin tubes arranged in parallel. An alternative is to provide an integral working medium flow channel, in other words, to provide an integral cavity under the inner groove surface , the cavity serves as a flow cha...

Abstract

The invention provides a rotary sewage source heat pump heat exchange device. The rotary sewage source heat pump heat exchange device is characterized by comprising a shell (4), a spiral chute (1) anda rotation driving mechanism, wherein the shell (4) is a cylindrical shell; the spiral chute (1) is spirally formed in the shell (4), a chute body of the spiral chute is provided with a circular-arcinner chute surface (11) serving as a sewage flow channel, and a working medium flow channel (12) is formed below the inner chute surface; and the rotation driving mechanism is used for driving the shell and the spiral chute (1) to rotate synchronously. According to the technical scheme, heat transfer efficiency reduction caused by sedimentation of pollutants in sewage on the surfaces of the flowchannels is avoided or alleviated; and besides, the rotation mode can reduce the downward flowing speed of the sewage, increase the heat exchange area and enhance perturbance in the radial direction of the flow channels, so that the heat exchange efficiency is improved, and the probability of sedimentation in the flow channels is further reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger in an air conditioning system, and more particularly to a sewage source heat pump heat exchanger. Background technique [0002] At present, in China, coal and natural gas are the main heat sources for heating in winter. China has a large population and a vast territory, which contributes a lot to the emission of carbon dioxide in the air, and the use of coal will emit other air pollutants. For this reason, heat pump technology is getting more and more attention. [0003] Heat pump technology can be divided into: soil source, water source, air source, combined heat pump according to heat source. Among them, the urban sewage source heat pump has the characteristics of warm in winter and cool in summer, small temperature change, stable water volume, and large heat energy storage. At present, the average daily sewage discharge in my country's cities is mor...
