Description
Technical field
The present invention relates to a kind of soda manufacture device and technique, more particularly to a kind of soda manufacture calcination process to be evacuated
Dust arrester and dust collecting process.
Background technology
Soda ash is one of important industrial chemicals, and it is widely used in glass building material, synthetic detergent, weaving, food, smelting
In the industrial productions such as gold, oil and chemical industry, occupied an important position in national economy, its yield and dosage often indicates
The flourishing degree of one National Industrial.Calcination process is last procedure of soda manufacture, and its quality operated is produced to soda ash
The Yield and quality and energy consumption of product have large effect, therefore calcine industry as among modern industry very important one
Ring.Conventional soda ash product mainly has two kinds of heavy soda ash and light soda ash, and the difference of its specification essentially consists in physical property
Difference, such as density size, particle size and shape, the bulk density of general light soda ash is 500-600kg/m3。
Soda ash calcining is by the wet stock NaHCO from filtration process3Na is changed into by the effect of light grey calcining furnace2CO3Powder
End, by multiple working procedures such as very long conveying, hydration, screening, crushing, coolings, turn into light ash or weight ash products, then pass through trestle
Bury and scrape conveying device conveying unlap station, thus complete calcination process.In the market involved by general calcination process
Induction system and dynamic equipment include：The light ashes of 1# bury scraper plate (two-wire), light grey vertical elevator (two-wire), that the light ashes of 2# bury scraper plate is (double
Line), the light ashes of 3# bury scraper plate (two-wire), weight ash vertically bury scraper plate (two), weight ash level buries scraper plate, the grey refeed line chain of two weights,
Two light grey plane rotor-vibrating screen, two weight grey plane rotor-vibrating screens, two light grey pulverizer, the grey pulverizer of two weights,
Three conveying worms, two light grey powder flow cooler, two weight ash powder flow coolers and six trestles bury scraper plate.It can be seen that
The characteristics of soda ash calcination process is：Complicated, the dynamic equipment of conveying flow is numerous, operation scene is difficult to avoid that emerging for dust.
The appearance of dust is especially difficult to avoid that in calcination process because in calcination process light grey stove burner pressure
Power has certain operation fluctuation, and (technological requirement is 0~-50mmH2O posts), furnace gas have interruption when entering heat alkali liquid tower boiler tube road
Formula cleaning (per stove per tour once, air intake system during cleaning), powder flow cooler are passed through air, conveying equipment sealing etc.
Problem, under the comprehensive function of above-mentioned factor, the phenomenon of " pressure-fired " can hardly be avoided in induction system, thus necessarily causes powder
It is elegant, influence site environment.Especially for the long-term operation for ensureing powder flow cooler, the more difficult effectively place of dry air of importing
Reason.
Current existing dust arrester is tail gas is entered the grey aeration tower of weight, but because of distance and path complexity, causes pipe
Line easily blocks.Therefore the anterior dusty gas of soda ash conveying equipment enters screening process, can have a strong impact on the production capacity of sieve；
Drawing mechanism of the dusty gas at rear portion through cooling device buries to scrape by trestle delivers into multiple package position, causes package mouth to steam
Seriously, so that environmental degradation, it is therefore desirable to design a set of dust arrester effectively run.
The content of the invention

Liquid level management and control system on liquid house steward's traversing section, the Liquid level of gas-liquid house steward's traversing section are the 5-10% of effective depth.
Gas part is by the suction for being arranged at gas-liquid house steward's vertical section exhaust end air exhausting device, on the traversing section of gas-liquid house steward
Run in layer and vertical section, after the scrubbed device of dusty gas, a small amount of dust is also contained in gas, the dust is in gas-liquid house steward
Traversing section A-B-C in, continue to have in wash water of the dust by the bottom of Action of Gravity Field natural subsidence to pipeline；Residual gas is then
Continue to be moved ahead to vertical section C-D by air exhausting device suction, have two parts effect a part of particle in vertical section still
It is by Action of Gravity Field natural subsidence to duct bottom, the very small micronic dust of another part particle diameter, by being arranged on gas-liquid house steward
Vertical section on common spray washing part water-washing away of spraying out, then be practically free of any powder in remaining gas
Dirt, it is discharged in external environment by air exhausting device.Air velocity in gas-liquid house steward described above is unsuitable too high, prevents because of speed
Spend the dust carried secretly in high gas flow and liquid is brought into blower fan, not only influence the dynamic balancing of draught fan impeller, can also cause row
Situation not up to standard is put, generally suggests that air velocity is 8-15m/s, optimal selection speed is 10m/s.
The parts such as the wash water storage bucket in device of the present invention can utilize the wash water storage bucket configured in current off-the-shelf item,
Only need to increase on the original basis that centrifugal pump, air exhausting device, screwed pipe, the seamless pipeline of each bore be some and steel construction piece etc., nothing
Independent design heavy caliber stuffing washing tower is needed, reduces arrangement trouble and floor load, the project investment amount of money is relatively low, is filled compared to tradition
Put, reduce investment outlay 80% or so.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
Modification, these improvement and modification also should be regarded as protection scope of the present invention.
