Description

A kind of chimney leftover bits and pieces water bath dust-removing sulfur method

Technical field

The present invention relates to a kind of chimney leftover bits and pieces water bath dust-removing sulfur methods, belong to Environmental-protecting dust-removing equipment technical field.

Background technology

The tail portion soot emissions of fluidized bed furnace and various heat source furnaces are one and make every effort to perfect project always, and qualified discharge is A kind of target, pernicious gas content is very high in flue dust, such as without processing, will cause seriously to destroy very much to ecological environment, The existing flue gas discharge capacity kiln within 10 ten thousand steres per hour, is not achieved the discharge standard of National Environmental Protection Agency's requirement.

Invention content

The problem to be solved in the present invention is to provide a kind of chimney leftover bits and pieces water bath dust-removing sulfur method, to fluidized bed furnace and various heat The tail portion flue dust of source stove is effectively treated in chimney leftover bits and pieces.

In order to solve the above technical problems, the present invention provides a kind of chimney leftover bits and pieces water bath dust-removing sulfur method, including：Chimney Shell, flue dust import, flue dust air inlet pipe, tubaeform sieve tray, the outlet of flue dust air inlet pipe, annular water spout, sparge pipe, valve, Pumping line, vacuum, water inlet pipe, screen cover, rushes dirt mud pipe, rushes mouth, ashpit, wet grey pool water level, forklift ash discharge water pump Slope road, wet ashpit, rushes dirt mud slope at clear water reserviors；It is characterized in that：Fluidized bed furnace offgas duct exports and flue dust import phase by air-introduced machine It connects.

Flue dust air inlet pipe and tubaeform sieve tray are mounted in funnel shaft.

Flue dust import passes through funnel shaft on flue dust air inlet pipe top, is connected with air-introduced machine outlet.

Flue dust air inlet pipe is passed down through the tubaeform sieve tray of polylith, below straight skewer to wet grey pool water level.

Flue dust air inlet pipe underwater penetration is adjusted according to emission request and air-introduced machine wind pressure, it is desirable that between 30-50mm.

Flue dust air inlet pipe underwater penetration is in 50mm or more, then dust removing effects are fine, but air-introduced machine wind pressure wants high.

Flue dust air inlet pipe underwater penetration in 30mm hereinafter, then air-introduced machine wind pressure require can low spot, but dust removing effects are poor.

Polylith is tubaeform, and sieve tray is welded in flue dust air inlet pipe, and every piece circumferentially by fulcrum on three fulcrums and inner wall of stack It is connected.

Full circular hole is bored on tubaeform sieve tray, drilling area is the 30-40% of the gross area.

Bore diameter is Φ 30-40mm.

Annular water spout is looped around flue dust air inlet pipe top, is located above the tubaeform sieve tray of most lastblock.

Multiple spray orifices are drilled with around annular water spout downwards, injection diameter requires to be Φ 12-14mm.

Nozzle hole number according to dust removing effects requirement and water pump size design, water spray is bigger, dust removing effects are better, On the contrary then dust removing effects are almost.

Annular water spout connects with sparge pipe.

Sparge pipe connects by valve with pumping line.

Vacuum is installed on unit fixed on water pump suction, is connected with water inlet pipe.

Water inlet pipe front end is equipped with screen cover, is not required to installation bottom valve, is not added with diversion.

The bore diameter of screen cover is between Φ 10-12mm.

The drilling area requirements of screen cover are within the 40-50% of the gross area.

Flue dust passes through flue dust air inlet pipe, when exporting ejection from flue dust air inlet pipe due to the pressure of air-introduced machine from flue dust import The water in wet ashpit is encountered, bulky grain grit enters in water.

Steam flow starts uplink, encounters the water mist on multilayer sieve tray, and little particle grit is mixed into water, and diameter is crossed in funnel shaft Wall flows into wet ashpit.

Air-flow after buck dust-removal and desulfurizing is arranged through chimney to air.

The pre- water of high temperature sulfurous gas in flue dust can generate weak acid.

Add soda ash or quick lime in sedimentation basin, neutralizes the acid-base value in water.

Gate is housed on pumping line branched pipe, is connected with dirt mud pipe is rushed.

Dirt mud pipe front end is rushed equipped with mouth is rushed, it is flat hole to rush mouth, and it is true by the hydraulic pressure and water of water pump to rush nozzle aperture discharge area Fixed, water, hydraulic pressure are big, rush mouth discharge area and can be larger, whereas to smaller.

It is required that rushing the pressure water that mouth is gone out, dirt mud can be gone out by lower spiral case outside ashpit from dirt mud slope is rushed, it is desirable that It is underwater undercurrent to rush dirt muddy water stream.

Top requires to submerge wet grey pool water level hereinafter, cannot leak out on ashpit.

It is 40-45 that the dirt mud slope angles v, which are rushed, with vertical line angle0Degree.

It is round volute shape to rush dirt mud slope envisaged underneath, adjusts gate, rushes pressure water that mouth is gone out in round spiral case In torn open upwards, by underwater parabola direction, dirt mud is gone out outside ashpit.

One side of face ashpit is equipped with forklift ash discharge slope road, and forklift ash discharge slope road is designed at wet ashpit one end, the angles gradient r For 13-150Degree.

Wet ashpit internal volume is required in 10m3More than, the gap for adjusting water level connects with sedimentation basin.

Sedimentation basin is used for precipitating the dust water that wet ashpit overflows, and internal volume is a little louder preferably.

Also there are one gap on sedimentation basin, outlet connects with clear water reserviors, and the clear water that sedimentation basin overflows is used for secondary cycle.

Chimney designs water bath dust-removing sulfur method in getting a foothold, and has following progress and novelty.

The floor space of dust pelletizing system has been saved in the design being combined into one, and saves investment.

Design pressure water rushes dirt mud, can use forklift ash discharge and entrucking, can save production cost, saves artificial.

Wet ash is filled by forklift to be transported outward, and dust cost of wheeling has been saved.

Using dust is managed outside water, secondary pollution environment is reduced.

Equipment is operated without special messenger.

With water closed cycle, water source has been saved, it is free from environmental pollution.

In conclusion water bath dust-removing desulphurization system advanced design, electricity consumption is few, high degree of automation, be it is a kind of it is very simple, Dust-collecting sulfur-removing method highly practical, effect is ideal can be widelyd popularize.
