Description
Technical field
The utility model relates to fire control smoke exhausting, Techniques for Indoor Air Purification field, particularly relates to a kind of electrostatic reinforced fibre and filters fire smoke clarifier.
Background technology
In recent years, along with the development of China's economy, cause the factor of fire to be on the increase, becoming of fire is more and more frequent.And fire is when occurring, due to combustible burning or imperfect combustion and macromolecular compound pyrolytic, often with the generation of a large amount of flue gas.Except the liquid state that the main component of flue gas is formed except burning and solid product suspension, also containing a large amount of CO, CO
2, poisonous, the pernicious gas such as HCl.The shielding of smoke particle in flue gas to visible ray makes visibility greatly reduce, and affects evacuation speed; CO, CO in flue gas
2, HCl, the toxic and harmful such as aldehydes, ethers that char particle and burning produce the also entail dangers to scene of a fire evacuates the healthy of personnel and fire-fighting and rescue personnel; If do not take control techniques to be directly discharged in outside atmosphere, also air pollution can be caused.
Fire control smoke exhausting device relevant in recent years also emerges in an endless stream always.But, various fire control smoke exhausting device ubiquity purification efficiency low, filter the problems such as malicious weak effect, complex structure, poor reliability.
Zhao Zhongming, Wang Jinbo discloses one " electrostatic reinforced fibre duster " (CN91204235.4) patented technology, this technology, primarily of a few part composition such as corona wire, high voltage source, Whirlwind barrel, fibrage, adopts " electrostatic+cyclonic separation+adsorption filtration dedusting " integrated compound design pattern.But this patented technology body is huge, complicated structure, resistance large, is only applicable to the little air quantity flue gas of process, the purification of Wind Volume fire smoke cannot be used for.
(ZL201420290013.2) patented technology that Chen Jun discloses " a kind of novel fire control smoke exhausting filter ", this technology utilizes smoke evacuation cartridge filter and dust suction grid to filter the impurity in dense smoke, reduces the pollution of particle in dense smoke.But this device only can carry out coarse filtration to flue gas, and filter cylinder resistance is comparatively large, and clean-up effect is undesirable.
(ZL201320484201.4) patented technology that Wang Lingxiu discloses " a kind of Novel firefighting fume extractor ", this technology is primarily of a few part composition such as main induced-draft fan, secondary induced-draft fan, spotlight, camera, telescope support and water jet device.During breaking out of fire, this device can be utilized to carry out multi-faceted flue dust absorption and carry out water mist spray process.But what this device was single utilizes water mist spray to catch flue dust, dust treatment efficiency is lower, and the worry of single water smoke poison function is poor; In addition, also there is complex structure in this device, the shortcomings such as poor reliability.
In sum, the subject matter that existing smoke evacuation system purification facility exists is: purification efficiency is low, filter malicious weak effect, poor reliability, complex structure.
Summary of the invention
The utility model is intended to overcome prior art defect, and object is to provide that a kind of purification efficiency is high, filter poison is effective, safe and reliable, structure simple, and the electrostatic reinforced fibre being applicable to fire control smoke exhausting technical field filters fire smoke clarifier.
For achieving the above object, the technical solution adopted in the utility model is: described clarifier is made up of pre electrified district, filtering area, anti-blow cleaning dust system and exhaust system.
