2results about How to "Prevent liquefaction" patented technology

The utility model discloses a kind of medical gas busbar of multiple monitoring function, it is related to medical gas busbar technical field, including connecting assembly, monitoring component, control assembly and gas cylinder, the connecting assembly includes secondary pipe, main pipe and air pressure sensor, the main pipe is fixedly installed in the inside of secondary pipe, the air pressure sensor is fixedly installed in the inside of main pipe, the monitoring component includes humidity sensor, dehumidifier and gas concentration detector, the dehumidifier is electrically connected with humidity sensor, the control assembly is set in the outside of connecting assembly, the control assembly includes control box, buzzer and pilot lamp, the buzzer and pilot lamp are electrically connected with control box.The utility model is under the joint action of humidity sensor and dehumidifier, the air humidity inside shell is detected by humidity sensor, air in atmosphere is separated by dehumidifier simultaneously, dry air is introduced into the inside of shell, prevent moisture liquefaction.

The application relates to the technical field of gas filtration, in particular to a honeycomb filter which comprises a box body, a wind guide pipe and a filter body in communication with the wind guide pipe, a cladding shell is arranged on the filter body, a plurality of heat exchange cavities are arranged between the cladding shell and the filter body, sealing plates are rotationally arranged at air inlet positions of the plurality of heat exchange cavities, a temperature control protection unit connected with the sealing plates and the heat exchange cavities is arranged in the box body. When the honeycomb filter is used, the plurality of heat exchange cavities between the cladding shell and the filter body are arranged, and a pure mechanical temperature control protection unit driven by a temperature sensing bag is matched, the number of heat exchange cavities participating in heat exchange can be automatically adjusted according to the change of tail gas temperature, accurate dynamic regulation and control of the working temperature of the filter body is realized, thereby effectively avoiding the thermal expansion and thermal stress accumulation of the filtering medium caused by continuous heat action, and micro cracks or sintering deformation of the honeycomb ceramic body is prevented.
