Description
Technical field
It is a kind of environment protection equipment the present invention relates to a kind of Phosphine gas purifier, at normal temperatures will be phosphorous
Air is directly discharged into after the industrial waste gas purifying of change hydrogen is up to standard.
Background technology
The fumigant insect killing that phosphine gas is widely used in the storage sectors such as tobacco, grain, leather, Chinese herbal medicine and linen-cotton is made
Industry.Overwhelming majority enterprise just directly discharges the poisonous phosphine gas in warehouse after insecticidal operation without purified treatment at present,
Ambient atmosphere environment is polluted, the safeguard procedures taken generally set certain safe distance around warehouse, make discharge
Phosphine gas concentration be substantially diluted.The domestic research to the purifier of phosphine gas is started late, at present to phosphorus
Change hydrogen carry out purified treatment equipment mainly have packed tower purifier, bubbling and spraying combination purification device, bubbling and
Spray combination purification device, light degradation purifier, combustion purification device and pressure swing adsorption purge device etc..
Chinese patent CN2456825Y, CN2456822Y, CN201320445Y, CN201300033Y and
The device for purifying phosphine gas of the announcements such as CN200999201Y is based on liquid phase reactor, and feature is purified with liquid phase scrubbing method
The efficiency of processing hydrogen phosphide is restricted by oxidant concentration height in liquid phase, when equipment works, the purification efficiency of phosphine gas
Fluctuation is larger, when gas is directly discharged in air after purification, however it remains the problem of being unable to qualified discharge, if will purification
Gas not up to standard afterwards is sent storehouse back to and circulated to be purified again, then sacrifices processing air quantity, add the clarification time.
The device for purifying phosphine gas that Chinese patent CN2442687Y is announced is based on solid phase reaction, and feature is stifling
Phosphine gas in storehouse is flowed through after filter, is sent back to again in storehouse and is carried out multiple iterative cycles until up to standard, in order to allow
Gas is formed in storehouse to be needed to lay a large amount of pipe specials in circulation, storehouse, occupies effective storage, meanwhile, circularly purifying must
So rate of ventilation in increase storehouse, extends the clarification time.
It is special based on the hydrogen phosphide purification processing unit that Chinese patent CN101959322A is announced is reacted with ultraviolet degradation
Point is the back-shaped pipeline that phosphine fumigation exhaust gas is made up of light transmissive material, degrades, then flows back under ultraviolet light
Stifling closed environment.Using circularly purifying mode, increase rate of ventilation in storehouse, extend the clarification time, sent out using ultraviolet source
Light, energy consumption is big, operating cost is high.
The hydrogen phosphide purification processing method that Chinese patent CN101732962A is announced, uses the caustic wash tower list of filling ceramic ring
Member and 2 column precious metal palladium charcoal catalytic oxidation units, are entered after phosphine containing industrial waste gas is preheated by reaction tower bottom,
Tower top is flowed out, and heating and thermal insulation is carried out to reaction tower with vapours, temperature be 100~150 DEG C, handle air quantity and be 36~
50m3During/h, its purification efficiency reaches that phosphine gas concentration is less than 1.0mg/m after 99.8%, purification3.Handle air quantity small, no
The normal temperature purified treatment of hydrogen phosphide can be realized, high energy consumption, operating cost are high.
Several purifiers are carried out after purified treatment to the industrial waste gas of phosphine containing above, and not only primary purification directly reaches
Mark discharge is difficult, and processing air quantity is small, is not suitable for applying on large warehoused.
The content of the invention
Primary purification is carried out to phosphine gas after storage fumigant insect killing it is an object of the invention to provide one kind directly up to standard
The poisonous Phosphine gas purifier of Wind Volume of discharge.
The Phosphine gas purifier that the present invention is provided includes air inlet, front end diffuser, filter element, framed bent, purification
Unit, bracket, filter element cover plate, main casing, clean unit cover plate, pressing handwheel, end diffuser and gas outlet.Front end is expanded
Dissipate device and end diffuser is located at clarifier main casing both sides, filter element, neck, framed bent, clean unit and bracket are located at
Inside clarifier main casing, filter element is designed using plank frame, is fixed in neck, with the filtering positioned at main casing body side surface
Unit cover is sealed；Clean unit uses columnar structured design, and one end is fixed on framed bent, and the other end is fixed on bracket,
Clean unit cover plate is located at the side of clarifier main casing, is fixed by pressing handwheel.
Filter element and clean unit can be changed after the once above fumigant insect killing end of job, and clean unit can be according to place
The size of air quantity is managed by 5~200 parallel combinations.
Filter element is a kind of device that effective detention purpose is played to dust in air, impurity, or even aerosol.Using
Plank frame is designed, and is typically made up of thick effect, medium air filtration medium, high-efficiency filtration media can also be used in some special occasions,
Improve detention efficiency.
A diameter of 100~1000mm of clean unit, is highly 200~2400mm, processing air quantity be 50~
500m3/h ；Scavenging material is seated in clean unit, and scavenging material can be with zeolite, molecular sieve, diatomite, three oxidations two
Aluminium or activated carbon is in the impregnated catalysts or potassium permanganate, manganese dioxide, silver nitrate, copper sulphate, copper acetate of carrier
One or more of solid particulate matters formed.When the industrial waste gas of phosphine containing passes through clean unit, hydrogen phosphide is thorough
Absorbing reaction is fallen, and does not produce secondary pollution, plays the purpose of environmental protection and periphery personnel health.
Filter element cover plate and clean unit cover plate are respectively arranged at the side of clarifier main casing, are easy to load and unload and change
Filter element and clean unit, and play a part of seal casinghousing.
During present invention work, the impurity such as dust, particulate matter in warehouse can be made by the effective detention of filter element, protection is played
The purpose of scavenging material in clean unit.Meanwhile, poisonous phosphine gas is complete with scavenging material reaction in clean unit, raw
Stayed in into phosphoric acid in scavenging material, effectively prevent the pollution to ambient atmosphere environment, it is ensured that the personal safety of periphery personnel.
The present invention handles air quantity from 500m3/ h to 50000m3/ h, purification reaction is carried out at normal temperatures, after primary purification
The concentration of hydrogen phosphide is not more than 0.3mg/m in gas3, can be directly discharged into air.
