Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings, but this description will not constitute a limitation to the present invention.

[0035] A device for detecting the amount of smoke from combustible combustion, comprising a sequentially connected combustion box, a smoke exhaust tube 7 and a detection device 11, the combustion box is a vertical combustion box 4 or a horizontal combustion box 14. An exhaust fan 10 is arranged behind the smoke exhaust tube. The smoke exhaust tube is a Φ10cm×60cm cylinder. The exhaust fan adopts Zhenghe APC10-G, the fan diameter is Φ10cm, and the exhaust volume is 1.5m 3 / min, the power is 30w, so that the smoke can pass through the photosensitive device constantly and smoothly, so as to facilitate the detection. The detection device includes a smoke collection device and an electronic detection device arranged in the middle of the smoke exhaust tube, and its operating structure is...

Abstract

The invention relates to a device for detecting combustion flue gas amount of a combustible material. The device comprises a combustion box body, a smoke fog exhaust pipe and a detecting device which are all connected with each other in sequence, wherein the combustion box body is a vertical combustion box body or a horizontal combustion box body; an exhaust fan is arranged behind the smoke fog exhaust pipe; and the detecting device comprises a smoke fog collecting device and electronic detecting equipment, wherein the smoke fog collecting device is arranged in the middle of the smoke fog exhaust pipe. The device for detecting the combustion flue gas amount of the combustible material, provided by the invention, has the advantages of lightweight, simplicity, convenience and easiness for carrying, can be connected with 220V household alternating current, can be used for combustion of foamed plastic filling materials, combustible decorative plates, external heat insulating plates and other materials as well as fire analysis under common environments, and is used for detecting the concentration of the smoke fog; and the concentration of the smoke fog is displayed on a display screen in the form of dynamic wave form in an intuitive and clear way, so that easiness for analysis is obtained.

Description

technical field [0001] The invention relates to the detection of the amount of smoke produced by combustibles, in particular to a device for detecting the amount of smoke generated by combustibles. Background technique [0002] In recent years, fires have occurred frequently in my country, especially the fire in the CCTV distribution building and the Jiaozhou Road fire in Shanghai, which have caused huge loss of life and property, highlighting the severe situation of fire safety in my country. In view of this, the Ministry of Public Security has issued a number of fire protection laws and regulations, further strictly improving the fire performance requirements of materials. However, at present, there are many types of fire performance tests for materials in my country, and the fire performance of materials cannot be identified in a short period of time, which delays the research and development and application of fire protection materials. The invention can conveniently id...
