Problems solved by technology

[0004] The current fire detection devices still have certain defects. Their common shortcoming is low sensitivity. The sensitivity of point-type infrared photoelectric smoke generally adopts a shading rate of 2% obs / m-25% obs / m. When it is large, the alarm can only be issued before the deflagration occurs. It takes a period of time for the fire to be detected and a large amount of smoke and flames are produced, which affects the evacuation of personnel and property protection.

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0034] The embodiment of the present invention is realized like this, as figure 1 The shown aspirating smoke detection device includes:

[0035] The shell part 1 is provided with a detection chamber inside;

[0036] The circulation detection part 2 arranged in the housing part 1, one end of the circulation detection part 2 extends to the outside of the housing part 1, and is used to suck the air in the fireproof space outside the housing part 1 into the detection chamber, and Inhaled air is cycle tested.

[0037] In the actual application of this embodiment, the shell part 1 is installed in the space where fire detection is required: such as machine room, library, cold storage, distribution box, etc., during detection, the circulation detection part 2 sucks the air outside t...

Abstract

The invention relates to an air-breathing smoke-sensing fire detection device, and belongs to the technical field of smoke-sensing detection. The device comprises a shell part which is internally provided with a detection cavity; and a circulating detection part which is arranged in the shell part, has one end extending to the outside of the shell part, and is used for sucking air in the fireproof space outside the shell part into the detection cavity and carrying out circulating detection on the sucked air. Circulating detection is carried out through a particulate matter sensor, the detection is very sensitive and is 1000 times more sensitive than traditional fire detection, and very early fire can be detected; and meanwhile, detection cost performance is high, installation and debugging are convenient, and life and property safety of people can be protected to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of smoke detection, in particular to an aspirating smoke detection device and method. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. [0003] In order to prevent fires as much as possible and give timely notification when a fire occurs, which can greatly reduce the damage caused by fire, corresponding fire detection is required. Traditional fire detection devices include ion smoke sensing devices, infrared photoelectric smoke sensing devices, ultraviolet or infrared flame detection devices. [0004] The current fire detection devices still have certain defects. Their common shortcoming is low sensitivity. The sensitivity of point-type infrared photoelectric smoke generally adopts a shading rate of 2% obs / m-2...
