The technical field is as follows: the invention relates to the field of gas-liquid separation devices matched with petroleum and natural gas exploration construction sites, in particular to a constant liquid level temperature-increasing degasser, which is particularly suitable for gas collection and detection of logging after gas-liquid separation of drilling fluid in petroleum and natural gas exploration construction.

Background art: for a long time, the electric continuous degasser is widely applied to the field of gas detection in oil and gas exploration, and is important gas-liquid separation equipment and means before gas detection. The basic working principle of the electric continuous degassing machine is that a motor drives a stirring rod to rotate at a high speed, drilling fluid is stirred in a degassing chamber and impacts an upper baffle plate to be crushed, and gas escaping after crushing enters a gas collection chamber and enters a pipeline for gas detector analysis under the suction of an external air pump. However, the application for many years proves that the electric continuous degassing machine is deeply influenced by the liquid level change of the drilling fluid, and the liquid level is frequently emptied. Air is pumped after the liquid level is emptied, and continuous degassing of the drilling fluid is interrupted. Meanwhile, the degasser only has simple mechanical crushing for the crushing of the drilling fluid, and most of gas dissipated after crushing is free gas, so that light hydrocarbon components are easy to dissipate, heavy hydrocarbon components are difficult to dissipate, and the gas for chromatographic detection only has the components from methane to n-pentane (C1-nC 5). In special cases, in order to be able to detect the components after n-pentane, it is necessary to increase the temperature in the gas path, since the heavy hydrocarbon components can be effectively dissipated at high temperatures. However, the high temperature merely heats the desorbed gas, and the heavy hydrocarbon gas components in the original drilling fluid are not desorbed and dissipated at the source.

The invention content is as follows:
