Embodiment Construction

[0027] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0028] like figure 1 As shown, an air-breathing aircraft cargo cabin fire detector with dehumidification and dust removal functions according to the present invention includes a detection chamber 9 , a control device 10 , a sampling pipe 2 and an air intake pipe 4 connected to the sampling pipe 2 . Several sampling holes 1 are arranged on the sampling pipe 2, and the material of the sampling pipe 2 is PVC, and the sampling pipes 2 are respectively arranged at a distance of 50 mm from the ceiling of the aircraft cargo compartment and at the return air outlet. The purpose of placing it at the return air outlet is to prevent the convection of the air in the cargo compartment from forming different air stratifications and the accumulatio...

Abstract

The invention relates to an air-suction-type plane cargo compartment fire disaster detector with dehumidifying and dedusting functions and solves the problem that an air-suction-type fire disaster detector cannot overcome influence of humidity and dust when compared with the prior art. The air-suction-type plane cargo compartment fire disaster detector comprises a filtering box and a membrane dehumidifying device, a filtering material is contained in the filtering box, the membrane dehumidifying device comprises a main temperature adjusting module, a membrane dehumidifying component and an auxiliary temperature adjusting module, the main temperature adjusting module is connected with the membrane dehumidifying component through a pipeline, the membrane dehumidifying component is connected with the auxiliary temperature adjusting module through a pipeline, an air incoming pipe is connected into the filtering box which is connected with the main temperature adjusting module, the auxiliary temperature adjusting module is connected with a detecting cavity through a cavity incoming pipe, and a cavity outgoing pipe is arranged on the detecting cavity. Through the dehumidifying and dedusting functions, detection accuracy is improved, and false alarm rate of a plane cargo compartment fire disaster detection system is lowered.

Description

[0001] technical field [0002] The invention relates to the technical field of fire detectors, in particular to an air-breathing aircraft cargo hold fire detector with functions of dehumidification and dust removal. [0003] Background technique [0004] With the rapid development of my country's air transport industry, air cargo transportation has become one of the important sources of income growth for civil aircraft. ) and more electrical equipment, it has a greater fire risk than other confined and confined spaces. Once a fire accident occurs, it will bring huge losses to the society. Therefore, fire detection and alarm in aircraft cargo compartments are becoming more and more important. [0005] At present, the difficulty in detecting aircraft cargo compartments is the high rate of false alarms. According to FAA statistics, only one out of every 200 fire alarms is a real fire alarm, and none of the 66 fire alarms issued by a domestic airline from 1997 to 2002 was a re...
