Description

Stirrer and stirring heat exchange device for liquid substance

Technical Field

The utility model mainly relates to the technical field of liquid substance treatment equipment, in particular to a stirrer and a stirring heat exchange device for liquid substances.

Background

With the development of science and technology, heat exchange operation of liquid substances is required in various industries or fields. For example, the amount of highly polluted liquid substances to be treated generated by cities and industrial and mining enterprises is increasing rapidly, such liquid substances to be treated belong to high pollutants, and if the substances are discharged due to improper treatment, the substances can cause great harm to the environment, for example, the liquid substances to be treated for chemical industry need to be crystallized and concentrated, and for example, seawater needs to be evaporated and concentrated in seawater desalination operation, and the like. In these fields, heat exchange devices are often used. Conventional heat exchange devices such as plate heat exchangers, tubular heat exchangers or other relatively stirred technologies.

The plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between the various plates through which heat is exchanged. The plate heat exchanger is an ideal device for heat exchange of liquid-liquid and liquid-vapor. The heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application, long service life and the like. The heat exchanger with the structure has the advantages of low heat exchange efficiency, very complex structure and high cost, and is not suitable for long-time continuous operation when in use.

A tubular heat exchanger is a heat exchanger which is widely applied. It is mainly composed of a shell, a tube plate, a heat exchange tube, a seal head, a baffle plate and the like. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket, flows in the pipe and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the shell-side tube heat exchanger is called. The heat exchanger with the structure has higher requirements on the structure, realizes heat exchange by only depending on the super-directional flow of liquid substances, and has lower heat exchange efficiency and poor heat exchange uniformity.

In addition, when a practitioner treats a liquid substance to be treated, the practitioner proposes to use a stirrer, but the conventional stirrer only utilizes a stirring rotational flow effect to form a vortex shape on the liquid substance to be treated, so as to improve the stirring effect and the treatment effect, but such conventional stirrer often only can rotate and mix the liquid substance in a cavity, and does not have the effects of diversion, dispersion and the like, so that the optimal stirring effect cannot be formed.
