Abstract
The utility model relates to the field of flue gas purification and environmentally friendly equipment, particularly to a flue gas purification dry powder injection device which comprises a powder cabin, a screw, a heavy punch, a hand wheel, a screw sleeve, a feed port and a discharge port, wherein the powder cabin is a cylinder cone base structural steel cabin; the feed port is formed in the top of the powder cabin, and the discharge port is formed in the bottom of the powder cabin; the hand wheel is mounted at the top of the screw, and the heavy punch is mounted at the bottom of the screw; the screw sleeve with an inner thread is fixed at the central shaft of the powder cabin; the screw penetrates through the screw sleeve; the rising and falling of the heavy punch are controlled by rotating the hand wheel; the powder cabin is mounted above a flue; the discharge port in the bottom of the powder cabin is directly communicated with the flue. According to the utility model, through adjusting the height of the heavy punch in the outlet, the material discharging of the powder cabin is opened or closed, the discharging speed of dry powder can be regulated, power is not needed for operation, the operation is simple, non-blockage is realized, and the flue gas purification dry powder injection device can be used under emergent situations such as the failure of the flue gas purification system to ensure the standard treatment of exhaust gas.
Description
The utility model is application number 2013202706068, and on May 17 2013 applying date, title is a kind of divisional application of gas cleaning dry powder injection apparatus.
Technical field
The utility model relates to gas cleaning environmental protection equipment field, especially a kind of gas cleaning dry powder injection apparatus.
Background technology
In the flue gas that coal-fired plant boiler and incinerator are discharged, contain a large amount of sour gas, bioxin etc., need to remove by flue gas purification system.The removal method of sour gas is that the removal method that sprays into the basic agent such as slaked lime powder or lime white or sodium bicarbonate particle ， bioxin in flue gas is to spray into activated carbon powder in flue gas, and therefore dry powder spraying equipment is extremely important in flue gas purification system.
At present, domestic dry powder sprays all needs power, the active carbon pay-off of the attached bioxin of suction that for example publication number is CN102600696A, and the dry-process deacidification system that publication number is CN202146715U, is all to adopt strength to carry.Strength is carried needs powerful mesohigh blower fan as power source, and conveyance conduit easily stops up and wearing and tearing.In the time that blower fan or pipeline overhaul, whole dry powder spraying system just cannot normally move, and causes the flue gas processing cannot be up to standard.
Summary of the invention
The purpose of this utility model is to provide a kind of without power, simple to operate, the dry powder injection apparatus occurring without stopping state, open stove, debugging, desulphurization system mechanical breakdown or obstruction etc. at boiler and in emergency circumstances can directly in flue, spray the medicament such as activated carbon powder or slaked lime powder, sodium bicarbonate particle, remove bioxin and sour gas etc. in flue gas.In the time opening stove, debugging, can pack slaked lime powder into and spray in advance for sack cleaner.
Concrete technical scheme of the present utility model is:
A kind of gas cleaning dry powder injection apparatus, is made up of powder storehouse 1, screw rod 2, weight 4, handwheel 5, screw sleeve 7, charging aperture 8, discharging opening 9; Powder storehouse 1 is cylinder cone die bed steel storehouse, and storehouse is top-loaded with charging aperture 8, is discharging opening 9 at the bottom of storehouse; Handwheel 5 is equipped with at screw rod 2 tops, and weight 4 is equipped with in bottom; The central shaft position that is fixed on powder storehouse 1 with female screw sleeve 7, screw rod 2 passes from screw sleeve 7; By rotation hand wheel 5, control weight 4 liftings;
Described powder storehouse 1 is arranged on flue top, and at the bottom of storehouse, discharging opening 9 is directly communicated with flue, and dry powder discharging is the suction that relies on negative pressure in the deadweight of dry powder and flue, without extra power is provided.
Further, described weight lower end is cone, can change the sectional area of discharging opening by weight lifting, and then regulates discharging speed.
Described powder bulkhead is equipped with the graduated visor 6 of mark, and in observable storehouse, material level changes.
Top, described powder storehouse is shaped as bell-mouthed feed hopper, is convenient to charging.
The utility model, by adjusting the height of salty hammer, opens or closes powder warehouse discharging, and can regulate the discharging speed of dry powder.The operation of the utility model device does not need power, simple to operate, without stopping up, can in emergency circumstances use in flue gas purification system fault etc., can guarantee flue gas processing up to standard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is A portion enlarged diagram in Fig. 1.
In figure: 1-powder storehouse, 2-screw rod, 3-discharge filter, 4-weight, 5-handwheel, 6-visor, 7-screw sleeve, 8-charging aperture, 9-discharging opening.
The specific embodiment
A kind of gas cleaning dry powder of the utility model injection apparatus, as depicted in figs. 1 and 2, is made up of powder storehouse 1, screw rod 2, discharge filter 3, weight 4, handwheel 5, visor 6, screw sleeve 7, charging aperture 8, discharging opening 9.
Powder storehouse 1 is cylinder cone die bed steel storehouse, and storehouse is top-loaded with discharge filter 3 and charging aperture 8, and storehouse sidewall is equipped with visor 6, is discharging opening 9 at the bottom of storehouse.Handwheel 5 is equipped with at screw rod 2 tops, and weight 4 is equipped with in bottom; The central shaft position that is fixed on powder storehouse 1 with female screw sleeve 7, screw rod 2 passes from screw sleeve 7.By rotation hand wheel 5, can control weight 4 liftings.
Described powder storehouse 1 is arranged on flue top, and at the bottom of storehouse, discharging opening 9 is directly communicated with flue, and dry powder discharging is the suction that relies on negative pressure in the deadweight of dry powder and flue, without extra power is provided.
Described weight lower end is cone, can change the sectional area of discharging opening by weight lifting, and then regulates discharging speed.
Described powder bulkhead is equipped with the graduated visor of mark, and in observable storehouse, material level changes.
Discharge filter is equipped with at top, described powder storehouse, can remove the dust in feeding and exhausting.
Top, described powder storehouse is shaped as horn mouth feed hopper, is convenient to charging.
The course of work of the present utility model is: dry powder is added in powder storehouse 1 by charging aperture 8, and the air in powder storehouse is discharged by discharge filter 3.Be rotated counterclockwise handwheel 5, drive screw rod 2, promote the height of weight 4, open discharging opening 9.Observe dry powder material level by the scale of visor 6 and change, change by the caliber size of rotation hand wheel 5 capable of regulating discharging openings 9, reach required discharging speed.While stopping using, turn clockwise handwheel 5 on earth, can close discharging opening 9.
