Abstract
The invention discloses a method for removing chemical gas pollution, and belongs to the field of ecological environment protection. According to the method, a harmful gas is sucked into an air inlet (4) of a first purifying chamber, then successively passes through a cycle hydrolysate (10) capable of strong continuously reducing temperature through a condenser tube for filtering and cooling, passes through a micropore ceramic filter screen (12) spraying out the hydrolysate (10), and finally passes through an anti-corrosive micropore sponge filter screen (11) for precise penetration hydrolysis, so that a gas without pollution is finally safely discharged. The technical scheme is capable of effectively radically removing harm of chemical flue dust and toxic gases to human, especially effectively removing harm of toxic haze.
Description
Technical field
The present invention relates to a kind of hydrolysis and neutralization, be specifically related to a kind of chemical gases pollution cleanup and send out, belong to ecological environmental protection field.
Background technology
Chemical industry poison dirt Odor stimulation harm row is difficult to greatly control, and in China, has report when form because of chemical industry exhaust emission the cancer district occurred frequently.
Summary of the invention
The design's method is called " hydrolysis and neutralization ".Its method is toxic gas to be sucked to a circulation hydrolyzate filter in airtight container, in hydrolyzed liquid, allocate " acid-base neutralization method " into, a certain predetermined substance is had to decomposition, chemical reaction, dilution or solvability, pass through multiple tracks micropore ceramics by circulating pump, sponge and so on, spray and wash away infiltration negative pressure filtration, allow chemical gas in liquid hydrolytic process imbibition effectively catching in hydrolyzate, reach removing harmful substance thereby detected and filtered by segmentation, discharging harmless Purge gas is object.
This technical scheme sectional arranges, and need adopt strong cooling filtration method, in case evaporation and diffusion to some chemical industry material.The multiple styles such as the design's main equipment can be movable type, fixed, the convenient job site of changing as requested.The design also can be fixed on underground, and sealing cooling is convenient in the place such as under water.
In factory, workshop, while work in the places such as warehouse, can design closed " fresh air purifying " method, i.e. fresh air suction displacement pernicious gas sucks in mobile or fixing hydrolytic purification equipment.By chemical reaction, filtration becomes innocuous gas and discharges after removing.Can effectively fundamentally remove chemical fumes and the harm of toxic gas to the mankind by the technical program.Especially can effectively remove the harm of malicious haze.
The enforcement advantage of this technology: 1, smog pernicious gas, must be by multiple tracks filter screen (have in the equipment of sealing thick, in, fine operation such as Multi-channel filtering such as grade) through hydrolysis system.Utilize negative pressure inhalation sucting reaction, through hydrolysis cooling, chemical neutralization, permeation filtration.Allow the first imbibition of harmful substance subparticle, then under the effect of filter screen multi-functional, harmful substance gas is fully and completely tackled in hydrolysis system, it is escaped without any dead angle.
2, hydrolyzate system can be processed recycling effectively in turn, as the gypsum (can be used for industrial raw materials, the fields such as decoration) producing after limewash " alkali " and sulfur dioxide or sour neutralization precipitation.
3, be implemented as power high, cost is low, and engineering is uncomplicated, and income is fast.Can allow factory mass make moving member assembling, small-sized, medium-sized and all practicalities of large enterprise's facility.
Compared with prior art: at present, prior art is that the smog of the interior atomized water spray null method (atomizing spray filtration method) of 1 gas flue and 2 centrifugal water smokes filters removing method.
Above two kinds of technology can be eliminated flue dust equally, follow this aerodynamic atomization to escape (be commonly called as and purify dead angle) but have micronic dust and pernicious gas, and harmful substance can not thoroughly be removed." acid-base integration method, just can address these problems the strainer filtering of this technology completely, is the technological concept of really effectively effecting a permanent cure.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: chemical gases toxic fumes hydrolysis and neutralization, is characterized in that: it comprises the steps:
Step 1: in clearing machine main body (1), pernicious gas sucks after first clean room's air inlet (4), successively by there being the powerful circulation hydrolyzate (10) that continues cooling of condenser pipe to filter cooling, again by there being the micropore ceramics filter screen (12) of hydrolyzate (10) spray, finally by the accurate infiltration hydrolysis of corrosion resistant microporous sponge filter screen (11).
Step 2: the Purge gas after hydrolysed filtrate is discharged by gas outlet (3) safety of the second clean room again.
Described clearing machine main body (1) is to be made up of erosion-resisting container.
Described circulation hydrolyzate (10) can peripheral hardware water tank and water pool, removes required to be applicable to jumbo flue dust.
Described temperature control hydrolyzate (10) is according to the water stage measurement of water fluid level controller (6), controls discharge water level by entering water electromagnetic valve (8) and discharging valve (9).By self-loopa water pump (5) (also can peripheral hardware water tank and water pool), hydrolyzate (10) is sent into circulation fluid spray chamber (2) again filter screen is carried out to spray work.Whole process is measured and is controlled by electric appliance control box (7) setting program.
Beneficial effect of the present invention is: reach removing harmful substance thereby detected and filtered by segmentation, discharging harmless Purge gas is object.It is by chemical reaction, will be harmful to after the filtrations such as chemical industry flue dust are removed and become innocuous gas discharge.Can effectively fundamentally remove chemical fumes and the harm of toxic gas to the mankind by the technical program.Especially can effectively remove the harm of malicious haze.
