Description
The utility model relates to a kind of cement equipment shaft kiln water deduster, belongs to the dust separation equipment in the cement machinery class, is particularly useful in the manufacture of cement machine shaft kiln chimney exhaust gas treating flour dust.
In the manufacture of cement industry, adopt vertical kiln process to produce in the cement process, a large amount of dust enter atmosphere in company with flue gas, are the keys that the industry is administered the three wastes.Processing for the cement equipment shaft kiln dust at present has dried, wet two kinds of ways.Dry method dust mainly is to adopt electrostatic precipitation and dust settling pocket technique, but these two kinds of methods are big because of investing, and operation and maintenance cost height, service life lack and fails further to promote the use of.In recent years, adopted the wet dedusting technology again morely, but because structural imperfection, its dust removing effects quite is subjected to the industrial and mineral condition effect, and performance is unstable, can not keep reaching the table discharging chronically.Equally also owing to structural reason, cause the easy fouling of water system, easily stop up, operation troubles is many, during handling failure, operation is difficulty relatively again, comes out so still there is desirable product so far.
The purpose of the present utility model: aim to provide a kind of novel concrete machine shaft kiln water deduster that can guarantee that dedusting is up to standard, reliable, fault is few, easy and simple to handle, easy to maintenance.
Above purpose is achieved through the following technical solutions.
This cement equipment shaft kiln water deduster is made up of body of the tower (14), the tower heart (4), chimney (8), flue (5) and water supply spray equipment, it is characterized in that:
Both sides, described body of the tower (14) footpath are two flues (5) that secant-shaped joins with it and two chimneys (8) of being located at shaft kiln smokejack (7) top join, and slightly to body of the tower (14) inclination, its top is provided with a controlled chimney pot (11) to described flue (5); Two chimneys (8) respectively be provided with a high pressure positive blower (9) over against the flue place, the front portion of this high pressure positive blower (9) is connected to a flat gas jets (1 0) that stretches into chimney (8) inner chamber; In described flue (5), be provided with simultaneously a controllable gate (13), be provided with baffle plate (24), capillary groove (23) and spray nozzle group (22) in the joint portion of flue (5) and body of the tower (4); The outer top of described flue (5) is provided with a manual unlatching machine (12); And link to each other with gate (13) with chimney pot (11) respectively through connecting steel wire.
Described water supply spray equipment is by water filter (16), and special moisture film nozzle sets (20), spray annular water pipe (17), spraying water pipe (15) and tower central sprinkler (2) are formed; Wherein said special moisture film nozzle by moisture film pipe support (21), sealing gasket (22), hold-down screw (23), positioning sleeve (24) and can be in pipe support arbitrarily the flat moisture film nozzle of rotational orientation form; Described tower central sprinkler (2) is made up of cylindrical shell (26), branch water cover plate (27), water-stop sheet (28), water inlet pipe (29), and described water-stop sheet (28) is provided with the eddy flow mouth.
Described body of the tower (14) top is provided with demister (1).
According to the cement equipment shaft kiln water deduster of such scheme design owing to adopted above-mentioned numerous improvement structure, make enter the deduster body of the tower from the shaft kiln flue flue gas earlier from top to bottom, from bottom to top discharge again from the tower mouth, prolonged the time of flue gas at the tower body inner chamber; Again because the high pressure positive blower and the spray nozzle group that flue outside, are provided with respectively with it and body of the tower joint portion; Simultaneously again because the acting in conjunction of the numerous spray equipments in body of the tower makes the abundant and dust effect of whole body of the tower inner chamber water body moisture energy.Therefore reach the high efficiency dedusting effect that not influenced by any working condition.

Below in conjunction with accompanying drawing, further describe the utility model, and provide embodiment.The utility model is installed in the cement equipment shaft kiln top.Two chimneys (8) link to each other with machine shaft kiln two chimneys (7), and flue gas tangentially enters same dedusting king-tower from two chimneys (8) through downward-sloping flue (5).Chew (10) with direct-connected high pressure positive blower (9) and single flat gas blowout flue gas is quickened, form whirlwind.Because flue (5) is downward-sloping, make flue gas fully mix collision in the gas wash tower bottom, and flue gas time of staying lengthening in whole gas wash tower.When the flue gas declivity enters gas wash tower tangential inlet place simultaneously, through spraying nozzle group (22) effect, wetted, the coalescence of dust, grit increase in the flue gas, quality increases, and get rid of Xiang Tabi with the eddy flow flue gas, a large amount of dust tower body moisture films (19) are caught, and finish first order dedusting.Flue gas continues to rise, and residual fine particle is through two-layer interlaced in the flue gas, and the water droplet washing of spray nozzle group (17) ejection that is evenly distributed and the formed cascade of tower central sprinkler (2), the tower edema with the heart involved film on the tower heart (4) top are caught, and finish second level dedusting; Purify flue gas and up transport,, enter atmosphere behind the water smoke in the removal purification flue gas through demister (1) through the high velocity air of high pressure positive blower (6) and circular gas jets (34) ejection.
Grey aqueous mixtures under removing goes out (35) through gas wash tower bottom buck and flows into seperator of ash and water; Plaster after the separation is sent to raw material mixer balling-up calcining automatically as cement producting material.Clear water after the separation is sent into the special moisture film nozzle sets (20) that the moisture film water endless tube is formed through water pump and water inlet pipe, filter (16), and spray annular water pipe (17), spraying water pipe (15) and tower central sprinkler (2) are finished the whole of water and recycled.There is not secondary pollution.
Flue (5) exit (being gas wash tower (14) tangential inlet place) is equiped with baffle plate (24) and capillary groove (23) prevents that dust exports the bottom because of turbid profit dust stratification because of flue (5) in backflow flue gas and the flue gas.
The clear water that recycles is through filter (16), elimination the solid-state foreign material that form in the water pipe, unlikely nozzle is blocked.
The tower central sprinkler (2) at the tower heart (4) top will enter the two-layer eddy flow of moisture, and the eddy flow water of water-stop sheet cavity of resorption effectively prevents dust stratification in the chamber.Epicoele eddy flow water forms desirable cascade moisture film through last minute water cover plate (30).
When certain parts of whole dedusting and recovery system break down must interim halt system operation, when carrying out troubleshooting.For guaranteeing that the machine shaft kiln can continue to produce, controlled unlatching machine (12) is opened Funnel Cover (11), closes flue valve (13).Because controlled unlatching machine (12) is by lever, three rope sheaves, steel wire rope, worm reducer etc. are Funnel Cover (11) and flue valve (13) balance interlock, shake gently to shake the hand, and just can simultaneously Funnel Cover (11) be opened and flue damper (13) cut out.
Use said apparatus, can in same gas wash tower, carry out the two-stage dedusting, good dedusting effect, purifying flue gas, to contain water smoke few, and dust content can be stablized and is lower than national specified discharge standard.Water system does not have obstruction, and ash water system does not have dust stratification, and do not have and return the cigarette phenomenon, stable and reliable operation, operating maintenance is easy.According to measuring producing 8.8 ton cement equipment shaft kiln water deduster operating positions per year: the utility model can reduce the ton to airborne release Dust Capacity 3500-5000 every year, has good social benefit.Dust under removing simultaneously reclaims can directly make cement producting material.By 60 yuan per ton, can be every year and use enterprise wound direct economic benefit 21～300,000 yuan.
