Heat exchanger

Abstract

The invention relates to the technical field of heat transfer machines, in particular to a heat exchanger which has high heat exchange efficiency and high practicability, and can effectively treat part of organic gases generated during heat exchange and does not easily cause pollution to the working environment, so as to improve use reliability thereof. The heat exchanger comprises a heat exchangebox, a heat exchange tube and a thermometer. A working cavity is arranged in the heat exchange box, the heat exchange tube is located in the working cavity, and the right side wall of the heat exchange box is provided with a feeding pipe and a discharging pipe, wherein a first valve and a second valve are arranged on the feeding pipe and the discharging pipe respectively. The heat exchanger further includes a fixing plate, a cooling device, a connecting hose and a sprayer. The fixing plate is fixed to the left side wall of the heat exchange box, the cooling device is mounted on the fixing plate, and the connecting hose is provided with a high pressure water pump. The heat exchanger further includes an exhaust pipe, an activated carbon adsorber, an ultraviolet ray emitter, a photocatalysisplate and a unidirectional exhaust device.

Description

technical field [0001] The invention relates to the technical field of heat transfer machinery, in particular to a heat exchanger.

[0002] As we all know, a heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid to meet the specified process requirements, and it is widely used in the production of related handicrafts; existing heat exchangers include heat exchange boxes , a heat exchange tube and a thermometer, the heat exchange box is provided with a working cavity, the heat exchange tube is located in the working cavity, the right side wall of the heat exchange box is provided with a feed pipe and a discharge pipe, and in the feed The first valve and the second valve are respectively arranged on the pipe and the discharge pipe. The top input end of the heat exchange tube passes through the left side wall of the heat exchange box and protrudes to the outside of the working chamber, and the bottom output end of the heat exchange tube passes through the The left side wall of the heat exchange box extends to the outside of the working chamber, and a drain valve is provided at the bottom output end of the heat exchange tube. The bottom temperature sensing part of the thermometer is wrapped around the bottom output end of the heat exchange tube, and the temperature sensor of the thermometer The warm part is in contact with the outer wall of the heat exchange tube; when working, put the hot fluid from the top input end of the heat exchange tube, open the first valve and put in the cold fluid to be heated from the feed tube, and the hot fluid in the heat exchange tube will be The heat is transferred to the cold fluid in the working chamber to complete the heat exchange, observe the thermometer indication, open the drain valve after the heat exchange is completed, open the second valve and release the cold fluid after heat exchange from the discharge pipe; however, In use, it is found that the heat exchange efficiency of this heat exchanger is low, and its practicability is low; moreover, it cannot handle part of the organic gas generated during the heat exchange process, which easily pollutes the working environment, resulting in relatively low reliability in use.
