Description
Technical field
The invention belongs to technical field of waste gas treatment, more particularly to a kind of petrochemical industry central laboratory emission-control equipment
And method.
Background technology
At present, petrochemical industry central laboratory is responsible in full factory's raw material and auxiliary raw material specification analysis, process units
Between control of product quality analysis and product quality analysis, the medium index analysis of public work, the quality of the product that dispatches from the factory is carried out
Supervision and check and other assistant analysis, laboratory are also responsible for point of the special operation conditions such as process units driving, parking and accident
Analysis, it is ensured that process units is smoothly driven success, is the core of enterprise product quality control is collection office, examine, experiment and scientific research
The multifunction test building being integrated.Laboratory is typically provided with various analysis rooms, chromatography chamber, physical property control laboratory, reagent storage, sample
Between, balance room, hot room and assistance building etc., the hydrocarbons such as test medium has petrol and diesel oil, liquefied gas volatile contain aromatic hydrocarbons
And hydrogen sulfide；Hydrochloric acid, nitric acid, sulfuric acid and other acid, in the acid mist of heat-treatment process bad student；Chemical reagent stored sample is more,
Leave concentratedly, wherein most chemical reagent are volatile；Volatilize a large amount of poisonous and harmful gas in sample analysis, storage, transfer process
Body.
Petrochemical industry central laboratory employs general ventilation and local ventilation from the angle for considering enterprise employee health
Mode.General ventilation is exactly that comprehensive air exchange is carried out in integral room, when the diffusion of poisonous and hazardous gas large area
During to the experiment interior space, it is necessary to discharge in time, while also to there is certain fresh air to be supplemented, poisonous and hazardous
Gas is controlled within the limits prescribed；Local ventilation be harmful substance generation after discharge nearby immediately, this mode can with compared with
Few air quantity drains substantial amounts of harmful substance, and energy is saved and effect is good, is to improve the feasible and economic side of existing laboratory condition
Method, it is also possible to adapt to the best way that new lab's ventilation is built.Poisonous and hazardous gas is entered by small operational facilities
The local ventilation process of row, prevents from being diffused into whole room.General ventilation or local ventilation are all by laboratory exhaust gas
After collection, the pressure produced by blower fan is discharged to outdoor by ventilation shaft.
Poisonous and harmful substance concentration exceedes the discharge standard of national regulation in the waste gas that petrochemical industry central laboratory produces
When, local environment air pollution quality can be caused, it is necessary to be discharged into air after administering.Such as patent CN205182468U《For testing
Room exhaust gas absorption device》, using two layers of activated carbon that two layers of spacing distance is certain in container, and placed in the middle of active carbon layer
Uviol lamp treatment of laboratory waste gas, the device has certain treatment effect to organic gas, and sour gas and particulate matter are handled
Effect is poor；Patent CN204395728U《CIT device for processing laboratory waste gas》, by gas sampling to multiple closed cabins, closed
Have different absorbing liquids processing in cabin, the device gas treatment effect certain to tolerance substantially, to tolerance and change in concentration
Gas is, it is necessary to adjust absorbent spray flux, complex operation；CN104437052A《A kind of chemical laboratory waste gas processing method and
Equipment》, this method can handle dust, acidity, alkalescence and insoluble gas dye environment, and the device dust inhaled with sponge absorbing layer
Attached, acid and alkaline gas two grades of absorptions of alkali lye, insoluble gas suctions, device equally exists tolerance ripple

It can effectively determine whether adsorption saturation is, it is necessary to which adsorbent is changed in device parking to adsorbent, and adsorbent layer is changed complicated；Using ultraviolet
Or photoionization technology, discharge gas in hydrocarbon content it is high when, there is explosion danger.
Exhaust-gas treatment has two purposes, one be from the health of office work personnel, it is necessary to the waste gas in laboratory and
When exclude；Two be the angle from environmental protection, should not cause atmosphere pollution.Standard originally is low, and handling process is simple, present
Standard requires higher, and technique originally is not suitable for substantially.
In summary, the problem of prior art is present be：Using liquid absorption method, when tolerance and concentration composition fluctuation, need
The composition of absorption operation parameter and absorbing liquid is adjusted in time, it is impossible to the waste gas that timely treatment of laboratory is produced；Existing absorption
Method processing, adsorption layer is generally fixed filling, and adsorbent layer is changed complicated, loaded using drawer type, useless to consider gas
Composition, when exit gas is not up to standard, it is necessary to which adsorbent is changed in device parking, and the present apparatus is using tiny structure absorption, can be
Plant running process changes adsorbent layer at any time；Using ultraviolet or photoionization technology, when hydrocarbon content is high in discharge gas, exist quick-fried
Fried danger.
