Description

Technical Field

[0001] The utility model relates to the technical field of natural gas detection, in particular to a natural gas monitoring and alarm device capable of automatic ventilation. Background Art

[0002] With the popularization of natural gas use, the demand for natural gas safety monitoring in industrial environments is increasing, which can improve the safety factor during the use of natural gas and reduce the occurrence of indoor air pollution caused by natural gas leaks.

[0003] In the prior art, when in use, the natural gas concentration in the room is detected by a natural gas monitoring alarm device. When a certain peak value is exceeded, the natural gas concentration sensor senses it and controls the alarm light through a controller to give an alarm to remind the user.

[0004] When in use, the prior art can only detect the concentration of natural gas and issue an alarm when the concentration exceeds the peak value. However, it cannot achieve automatic ventilation, which may cause users to inhale too much natural gas and cause varying degrees of harm to the body. There are still certain safety hazards, and the leaked natural gas cannot be recycled. In view of this, a natural gas monitoring and alarm device with automatic ventilation is provided to overcome the above defects. Utility Model Content

The alarm light body flashes and a whistle sounds to remind the user, and the fan body is automatically started.

[0008] As a further description of the above technical solution: a circular through hole is opened on the right side of the wall body, and the diameter of the circular through hole opened on the right side of the wall body is consistent with the diameter of the fan body. The fan body quickly discharges the air in the room, and the mixed gas of the discharged natural gas and air first passes through the filter to separate larger particulate impurities.

[0011] As a further description of the above technical solution: the number of the fixed plates is two, and the fixed plates are parallel to each other, the wall body and the controller are parallel to each other, the wall body and the natural gas concentration sensor are parallel to each other, the air in the natural gas is adsorbed by the adsorbent, while the hydrocarbon components are not adsorbed, thereby achieving the separation of air in the natural gas.

[0012] As a further description of the above technical solution: the filter is fixedly connected to the rear end of the fan body, and the filter and the fan body are parallel to each other, and then the adsorbed natural gas is discharged into the liquefied natural gas cold box body through the second air inlet pipe, and the liquefied natural gas cold box body is used to liquefy the natural gas for storage.
