Problems solved by technology

[0004] However, direct discharge of flue gas containing a large amount of harmful components such as hydrogen hydrocarbons into the atmosphere has an impact on PM2.5, pollutes the environment, and causes harm to human physical and mental health
Moreover, the high-temperature oil will be heated repeatedly, causing the volatilization of hydrogen hydrocarbons and other components, and the properties will change. It usually takes three to five months to replace the new oil, which will not only cause waste, but also cause environmental damage if the waste oil is not properly treated. Secondary pollution

Abstract

The invention discloses a sealed constant temperature bath which comprises a bath body, a flange cover and a sealing ring. The bath body is made of materials which are resistant to corrosion and pressure and cannot react with oil products. The flange cover and the bath body are sealed. The sealing ring is arranged between the bath body and the flange cover. At least one installation hole is formed in the flange cover. A temperature gauge insertion tube is connected with the flange cover through the installation hole. According to the sealed constant temperature bath, the normal-pressure sealing structure is achieved, the open-type structure of a traditional constant temperature oil bath is improved fundamentally, and oil and oil steam are automatically recycled in the heating process, so that a sealed self-circulation system is formed, no pollution is caused to the environment, and green verification and calibration are achieved.

Description

technical field [0001] The invention relates to a constant temperature tank, in particular to a sealed constant temperature tank used under normal pressure. Background technique [0002] The constant temperature oil tank is the necessary equipment for thermometer verification, and the temperature range is 100 ~ 300 ℃. It is mainly used for verification and calibration of liquid-in-glass thermometers, thermometers of resistance elements, thermocouples, and bimetallic thermometers. There are such devices in the metering institutions above the county level or in large enterprises in my country, and there are several thousand units in stock nationwide. [0003] The working method of the constant temperature oil tank is open, through the temperature controller, the heater is controlled, and the high temperature medium such as silicone oil and cylinder oil in the oil tank is directly heated to heat up and keep the temperature constant. As the temperature rises in the range of 10...
