Description

Natural gas leakage laser telemetering explosion-proof holder with constant temperature control function

Technical Field

The utility model relates to a telemetering measurement cloud platform technical field specifically is a take explosion-proof cloud platform of natural gas leakage laser telemetering measurement of thermostatic control function.

Background

Methane is a combustible gas and is the main component of natural gas. Plays a great role in providing energy in the industrial and civil fields of China. As is known to those skilled in the art, natural gas is a high quality fuel and is colorless and odorless. The explosion limit of natural gas is 5-15%, if the natural gas is leaked carelessly in transportation, storage or use, in the range of the protection limit, violent explosion can occur when exposed fire occurs, and the accident that people suffocate due to sudden increase of local concentration caused by natural gas leakage also occurs. In natural gas use, safety is the first place. The natural gas leakage is prevented, besides the strict sealing design of the transmission system, the leakage position is monitored in real time, and once the leakage is found, the alarm is given immediately.

The technical principle of the currently used laser methane telemeter is that a laser built in the telemeter emits a specific laser beam, the specific laser beam penetrates through the upper part of a target area (such as a pipeline joint or a facility space), and the specific laser beam strikes a reflection target object at the other end, part of the laser beam reflected back enters a detector and is converted into an electric signal, the concentration of methane can be analyzed by analyzing the change of the electric signal, and because the laser in the waveband can only be absorbed and interfered by methane, the laser only reacts to the change of the concentration of the methane, so that the concentration of the methane can be accurately judged, and no error exists.

The structure of the laser methane telemeter product comprises an explosion-proof metal cylinder, wherein components such as a laser transmitter and the like are arranged in the metal cylinder, and the national requirements on explosion prevention in environments such as explosive gas, dust and the like must realize intrinsic safety and explosion prevention of all devices related to circuits. In practical use, the core component of the device, the laser, is found to be sensitive to ambient temperature. Because the explosion-proof metal cylinder body is required to be designed in a sealed and closed manner, heat generated by the operation of the internal electronic components cannot be fully released out through air convection after being accumulated. In addition, under outdoor open conditions, especially environments such as high temperature in summer and sun exposure, heat accumulated in the metal cylinder body enables the temperature to rise sharply, and therefore the laser fails. The problem puzzles engineering technical personnel all the time, thinks that multiple way implementation cooling is handled, for example increase to separate the heat exchanger and reduce to absorb environment heat etc. but inside heat is got rid of unclogously, and whole effect is not good, and there is not ideal measure to the cooling of the laser telemetering measurement cloud platform that can detect methane leakage at present, for this reason, we propose a natural gas leakage laser telemetering measurement explosion-proof cloud platform of constant temperature control function.
