Description
[technical field]
The utility model relates to semiconductor and photovoltaic industry pipelines and petrochemical pipelines fire-fighting system technical field, and specifically a kind of band chemicals buffer-type outlet flame is caught exhaust apparatus.
[background technology]
In recent years, domestic semiconductor and photovoltaic industry develop rapidly, and relevant processing procedure is increasingly sophisticated especially, and the related chemicals of manufacture of semiconductor has suitable danger mostly, and any carelessness all might cause the loss of serious personnel and equipment.Show according to 83 years to 87 years operation disaster analysis data of Hsin-chu science park, because the professional disaster that chemicals causes accounts for second of production disaster type.Its major accident has fire explosion, and sootiness is polluted, dangerous liquid gas leakage etc.Therefore, how improving these security of high-risk chemicals in transportation, will be the important ring during semiconductor and photovoltaic exhibition industry safety are considered.
Dangerous chemicals mainly is divided into according to its characteristic, combustibility, acidity and 3 big types of alkalescence.Wherein the safeguard procedures of flammable chemicals are mainly round to prevent that it from leaking or cause that fire is main because of volatile vapors accumulation.At present, relate to the storage of flammable chemicals, all can be provided with explosion-proof in transmission and supply system and the silicon chip cleaning equipment and the venting of dust explosion structure, forced ventilation device (Exh), and fire-fighting system.
Wherein fire-fighting system is passed through heat supply for fear of the fire that is caused by combustible chemical, air-conditioning, and ventilating system or smoke evacuation mist pipe skewered cause bigger property loss to full factory, the pipeline that links to each other with equipment uses the fire prevention material mostly.Recently; Further in fire starting stage pneumatic corresponding corresponding scheme fast as early as possible; Increasing manufacturer has arranged VESDA (Very Early Smoke Detection Apparatus) except the fire supply system spray system, i.e. unusual early-stage smog detection equipment.Though VESDA can more early confirm the generation of fire alarm and start corresponding fire-fighting mechanism according to the inhaled air sample; But because organic chemicals usually can produce volatile combustible steam in system pipeline and equipment; The transmission speed of high imflammable gas burning like this is very high; When VESDA can't guarantee fully that also flame or trickle Mars are not forced ventilation unit (EXH) extraction, spread, cause the diffusion of fire along air draft pipe.
No matter be the fire-fighting system place optics or hotness probe or VESDA device interior by the asepwirator pump inhalation device in the probe of air sample, all belong to active property watch-dog.Active property equipment whole fire-fighting system usually can occur behind power failure that the human operational error causes or the ageing failure of sensor own in paralyzed state.
For light sensation flame detecting device, occur easily because the relation that flame light is blocked by barrier can't detect the generation of flame.For the temperature sense detector, temperature was set the low misoperation that occurs fire-fighting system easily, set too high meeting and made flame generation back system still be in closed condition.In addition; For highly sensitive VESDA; Because its air sample is sucked by the air pump at system place; If it is improper that sampling import and extraction speed are set, the gas extraction system (EXH) of equipment itself makes intensity of a fire diffusion prior to VESDA with flame suction ventilation pipeline in the time of the flame generation can occurring, and is uncontrollable.
[summary of the invention]
The purpose of the utility model is exactly to solve above-mentioned deficiency, and provides a kind of band chemicals buffer-type outlet flame to catch exhaust apparatus, realizes the propagation for flame in the airduct of bleeding or Mars, thereby prevents that flame from connecting the diffusion of pipeline to device external.
For realizing that above-mentioned purpose the utility model designs a kind of band chemicals buffer-type outlet flame and catches exhaust apparatus; Comprise flame catcher, main exhaust duct, said main exhaust duct is through the flange-interface flame catcher that is tightly connected, the port of export of the said flame catcher corrugated flexible hose that is tightly connected; Said main exhaust duct is provided with bleeding point, exhaust port; Said bleeding point place is provided with air cleaner, and said exhaust port connects the buffer memory gas tank through pipeline, and said buffer memory gas tank is provided with liquid level sensor, liquid gas air inlet and leakage fluid dram; Said liquid gas air inlet connects liquid gas ventilation shaft, and said leakage fluid dram connects Drainage pipe.
Be equipped with pneumatic or electrically operated valve on the said Drainage pipe.
Said main exhaust duct adopts the anticorrosion stainless steel material to process.
Said air cleaner adopts not combustible material to process.
The utility model is compared with prior art, and is simple in structure, novel, safe in utilization, and the passive structures design makes gas extraction system when electric power system fault, still keep the inhibition to the diffusion of flame in ventilating system; Automatically the buffer memory gas tank of draining makes the fuel gas of the interior band chemicals of discharging of chemicals pipeline separate the back through liquid gas and is included in same gas extraction system.The modularization making of buffer memory gas tank, main exhaust duct and flame catcher can carry out the maintaining work of quick and low difficulty.
