Board net demist implement arenaceous filter canister is made by polyethylene raw material commonly, hand in fold fold set facility inside. Wire network demist implement medium wire network is general by high pressure polyethylene or fight corrode stainless steel plank to make and become. Fiber demist implement spin material criterion in order to get together third is rare see more with Bo fine.

3, the foot steps type acerbity mist to purify a law

The effect that the fundamental of means of equipment of off-gas treatment of this kind of industry is use active force, inertial moment of force or centripetal force makes fine grained content and steam system depart come out, purify eye ground more than then. Set stock commonly to fold the demist that sorts type implement, demist of axial shedding type implement etc.

4, acerbity mist purifies fluid Zuo to digest absorb a law

Fluid Zuo is digested absorb in including a hand to wash law and caustic soda solution commonly lawful. The solution that caustic soda solution digests the NaOH of the Na2CO3 that absorbs common sorbent to have 10 ％ , 4%~6% and NH3 to wait. What choose profession of only chemical industry key of off-gas treatment equipment has gush to drench tower of tower, expanded plastics tower, filling tower, inclined orifice plate, rapid ball tower. Its key purifies a principle is to make gas, fluid enough lay a finger on, acerbity, alkaline in close, promote then purify efficient.

Fluid Zuo digests the dominant position that draws a law is equipment project investment is inferior, treatment craft is more simple and easy. Blemish is: It is very easy that A is returned in northward winter do not have a law because of the knot freezes and creating facility everything is run normally; Because B contains not easy dissolve to solve the NO of water in nitric acid mist, consequently fluid Zuo is digested absorb a law to be opposite of nitric acid mist purify efficient relatively low; Water consumption of C specific power consumption is big, run expenditure tall; D produces pollution very easily 2 times.

5, acerbity mist purifies law of solid state adsorption

Show level this sorbent already was made in several those who gain a success is obtain to apply in the industry. It can purify the multifarious acerbity energy of life such as natrium of hydrochloric acid, cyaniding, vitriolic, hydrochloric acid, glacial acetic acid, ammonium sulphate (mist) . The pickling passivation that is worth the intermittence blowdown under 1000 Mg/m3 in applicable chroma especially operates field actually. Common sorbent has the balata of sieve of element of active carbon, carbon, silicon, slime that contain ammonia to wait.

6, the advantage that adsorptive law purifies equipment of off-gas treatment of acerbity mist industry is:

A, equipment is simple and easy, real operation is convenient;

B, dry try treatment technology, do not cause pollution 2 times;

The azotic oxidation that eliminate of relatively can C, good land causes as nitric acid mist adds up to the environment of content to pollute.

Its blemish is: Because the adsorptive cubage of sorbent is insufficient, bring about equipment tremendous, and whole process is operated actually for intermittence. Consequently, adsorptive law only applicable purify solve acid to spend the organic waste gas with inferior value mistily.

As comparative as current other sorbent, sorbent of SDG acerbity mist has following advantage: A adsorption whole process with dominant of organic chemistry adsorption, the corporeal character of generation is smooth, because this adsorption undertakes the sorbent after can be cast instantly,fall, need not give somebody a new lease on life, saved opposite treatment craft and equipment to expend; B sorbent raw material and make low cost; C adsorption is efficient, adsorptive volume is large. Adsorptive law purifies equipment of industrial off-gas treatment to adsorber of type of adsorber of fixed bed reactor, move bed adsorber, canal waits.

　　6, the main use that acerbity mist purifies a tower

It is applicable certain chroma is worth blowdown corrode system of acerbity mist steam, apply to the field such as outpatient service of chemical plant, electronic parts, hospital, school, institute.

　　 7, organic waste gas purifies acerbity mist the construction of the tower

Acerbity mist purifies a tower to be drum tectonic means, whole tower is formed by 3 parts, namely the lay aside fluid, mouth that take energy of life, from gush, take off work and exhaust, outfit of centrifugal water pump is in acid-proof sex two side, enter with the tower, passageway provides link, respective outfit is in plastic ball from gush inside

Acerbity mist purifies a tower to be glass reinforced plastics figuration of anticorrosive an organic whole, the structure is compact, fight corrode, heat-resisting, the surface is bright and clean;

Divide water share: Plastic make protection cause lunt depart to come out;

Aspersion ministry: Zuo presses aspersion to cause mirage, or so minutes a few paragraphs of outspread lay a finger on settle promotion action;

Inserts: Sea urchin or imperial crown, figuration of PP qualitative an organic whole;

Cistern of circulatory system stainless steel must want to defend the position that block water up, line of 50mm water level risks water blowdown canal;

Window: 5mm is thick completely transparent pressure overcome force board to make;

Full automatic turn on the water equipment: Fluid of switch of water pump pressure automation system pattern;

Add spray pump: Choose 22L/H anti-corrosive variable pump.

8, acerbity mist purifies a tower to run medium maintenance in equipment of industrial off-gas treatment means

Acerbity mist purifies a tower is in order to solves blowdown of 2 oxidation sulfur, remove dust equipment is divided can first-rate take off the 2 oxidation sulfur in dividing soot, after all previous purifies equipment of tower industry off-gas treatment via acerbity mist, can produce make a vitriolic ammonia organic fertilizer. But how Where is the dust catcher of to decoke of that care and maintenance with reasonable ability? Sister of below young lady says for groups big:

1: When acerbity mist purifies a tower to move, the cyclone of the body can comprise vortex, once vortex comprises be the subsidise that do not have a law really, it is to encounter soot steam system distinctly
