Brief Introduction: |
Efficient dust collector is containing dust and gas by the lower open type flange into the filter chamber, the coarser particles directly into the ash bin, the filter bag filter, dust resistance to stay on the surface of the bag dust gas bearing and gas net bag to the net gas chamber, is discharged into the atmosphere through a fan. When the dust on the surface of increasing, program-controlled instrument began to work, one by one to open the valve, so that the compressed air through the nozzle of bag of spray blowing, so that the bag with a sudden expansion, in under the action of the reverse flow, give the bag dust quickly out of the bag into the ash bin, dust discharge by the ash valve discharge.
Performance of dust collector can handle the amount of gas, gas is expressed by means of dust collector resistance loss and the dust removal efficiency. At the same time, the price of precipitator, operation and maintenance costs, the use of length and operation management of the difficulty is also considered the performance of an important factor. Dust collector is used in boilers and industrial production facilities.

| Technology |
(1) wet desulfurization technology
Generator, boiler, furnace exhaust of sulfur-containing high-temperature flue gas directly into the wet desulphurization and dust removal equipment, the flue gas enters absorption tower, and absorption tower upper jet grout contact, through the grille in further gas-liquid contact reaction, thereby the SO2 removal in flue gas, NOx and other fine dust; slurry into the absorption tower at the bottom of the reaction tank, through the circulating pump returns back to the absorption tower upper jet, the SO2 in flue gas is washed. Flue gas after leaving the absorption tower into vertical arrangement of the demister, the wet flue gas state in the maximum droplet removal.
Selection of main materials of the desulfurization tower:
According to the flue gas temperature, corrosion resistance, selection of 316 stainless steel, carbon steel shell lining anti-corrosion resin, modified PP, PVC, glass steel, and granite.
Selection and use of desulfurization agent:
Lime water desulfurization
Water desulfurization with lime is a kind of cost lowest a desulfurization technology, in water with lime as desulfurizer process, only the consumption of low cost of Cao, waste is a mixture of CaSO4 and CaSO3 and dust, water in the system can permanently recycled.
Desulfurization process is more complex:
1, the flue gas SO2 and water H2O to generate sub sulfuric acid H2SO3.
2, the flue gas in the SO2 and spray water in the Ca (OH) 2 reaction to generate CaSO3 precipitation.
3, the flue gas in the CO2 and spray water in the Ca (OH) 2 reaction to generate CaCO3 precipitation.
4, CaCO3 was replaced by H2SO3 in the circulating water spray process CaSO3.
5, in the process of circulating water spray CaSO3 is the oxygen in the flue gas CaSO4 into O2 precipitation.
In order to reduce the consumption of Cao (lime), in circular spraying water, should maintain the pH value of water spray in 5-6, due to spray water H2SO3 concentration increasing pH below 5.5, mixing lime water, the pH value of water spray reached more than 8. |
(2) sodium alkali desulfurization
Using NaOH or Na2CO3 as the desulfurization agent is the most simple and easy to use method, management is more convenient, there is no sediment, but the spray water can not be used for permanent circulation, must be periodically replaced. In the process of running a higher cost of NaOH or Na2CO3.
Desulfurization process:
1, the flue gas SO2 and water H2O to generate sub sulfuric acid H2SO3.
2, H2SO3 and NaOH generation Na2SO3.
3, O2 is oxidized to Na2SO4. in the water spray process Na2SO3 |
（3) ammonia soda process desulfurization
Ammonium hydrogen carbonate (NH4HCO3 as a desulfurization agent, with natrium alkali method is as easy to use management is convenient wait for a characteristic. Ammonium bicarbonate is added in the circulating water can get paid products sub ammonium sulfate or ammonium sulfate, because of the ammonium sulfate or ammonium sulfate solubility is much smaller than the solubility of ammonium hydrogen carbonate and in the running process of sulfite ammonium or ammonium sulfate will from the circulating water precipitation.
Desulfurization process:
1, the flue gas of SO2 and water in the formation of NH4HCO3 sulfite (NH4) 2SO3.
2, NH4SO3 is oxidized by 2SO4. (NH4) O2 in the water spray process. |
(4) double alkali desulfurization
Sodium Alkali FGD process can be used with water lime or calcium carbide paste Ca (OH) 2 reduction of sodium alkali (dual alkali desulfurization), reduce the consumption of sodium alkali, reduce the running cost of the desulfurization process, get paid products gypsum deposit,
So as to achieve the water in the system can be recycled, no discharge of waste water. In the process of desulfurization, sodium alkali only play a role in the transition, in the whole process of the operation of the theory is not consumed.
Desulfurization process:
The use of soda and lime as desulfurizer, dual Alkali FGD. Sulfur dioxide generated by coal combustion process is water absorption to generate sulfite and with water Na + formation of sodium sulfite.
Sodium sulfite and calcium hydroxide reaction of sodium alkali and calcium sulfite (can be oxidized into calcium sulfate precipitation).
NaOH+SO2, Na2SO3, Na2SO3+O2, Na2SO4,
Na2SO3+Ca (OH) 2, NaOH+CaSO3: Na2SO4+Ca (OH) 2, down NaOH+CaSO4
After the reduction of sodium alkali solution in the spray to continue to use, sodium alkali in the circulation process only play the role of the media in the whole process of the desulfurization reaction is not consumed,
The formation of calcium sulfite and calcium sulfate precipitate in the reaction is regularly discharged. |

Cyclone dust |
| Cyclone dust collector with dust flow is composed of an air inlet pipe into the dust collector in the tangential direction, in helical vortex is formed between the outer wall of the precipitator of the inner wall of the shell and the exhaust tube, down to do rotation movement, under the action of centrifugal force, dust particles reach shell inner wall and in under the joint action of the downward flow and gravity, along the wall into ash hopper, purified gas through the exhaust pipe excluded. |
| Features: |
| Cyclone type dust collecting device has the advantages of simple structure, no moving parts, the advantages of high dust removing efficiency, adaptability is strong, the operation and the maintenance is convenient wait for a is one of which was widely used in industrial dust removal equipment. Usually case, cyclone dust collector of the capture set 5-10 m above the dust, the dust removal efficiency can reach 90% |
| Applicable industry: |
| Food, feed, leather, chemical, rubber, plastic, grinding and casting boilers, incinerators, ceramics, asphalt, cement, surface treatment, electronic, semiconductor and other. Use in coarse particle dust or coarse powder separation and pre - treatment. Such as: sawing, sanding and grinding powder; cloth scraps, sawdust, copper wire side and so on. |
