Abstract

The invention discloses an explosion-proof heating device which comprises a heating controller, a connecting wire, a heating component and an electrochemical sensor. The heating controller is connected with the heating component through the connecting wire. The electrochemical sensor is disposed on the upper portion of the heating component. The explosion-proof heating device further comprises a thermocouple which is disposed inside the heating component. The heating controller judges whether to supply power to a heating strip in the heating component for heating or not according to the temperature fed back by the thermocouple disposed in the heating component. The explosion-proof heating device has the advantages that certain temperature around the electrochemical sensor can be kept, and electrochemical sensor detecting equipment can effectively detect the concentration of poisonous and harmful gases and give out alarms; whether heating is needed or not can be judged accurately to save resources; the heating component is of a reasonable integral structure; the deep thread structure of the inner wall of a heat guide pipe facilitates heat transferring; a locking sleeve is used as a connecting part, and safety and reliability are achieved; a blown fuse is used as the secondary guarantee of the heating device, and explosion accidents can be prevented.

Description

technical field [0001] The invention relates to a heating device, in particular to an explosion-proof heating device. Background technique [0002] At present, many petroleum and chemical industries are installing gas leakage detection instruments for the safety of production. Some of these detection instruments use electrochemical sensors, especially for the detection of toxic gases, such as H2S, C0, etc., and a large part of them are electrochemical sensors. Sensor equipment, detection equipment using electrochemical sensors, has the advantages of stability and reliability, but it also has a fatal disadvantage, that is, when the ambient temperature is low, its detection deviation is large, and when it is lower than minus 40 degrees, it may even There is no reaction at all, which greatly limits the application of electrochemical sensor detection equipment. Contents of the invention [0003] The purpose of the device of the present invention is to overcome the fatal defec...
