Abstract
The dust-removing energy-saving device comprises a spray tower, a sedimentation tank, a circulating pump, an air inlet flue, a smoke exhaust flue, a sewage pipeline and the like. The spray tower is respectively connected with the flue inlet and the sewage pipeline, and the other end of the sewage pipeline is connected with the sedimentation tank. A purification cavity is arranged in the spray tower, and after the dust-containing flue gas passes through the purification cavity, harmful gas and dust are purified and removed. The blackness of the purified flue gas is of the grade of Ringelmann, and the dust concentration is 180 mg/standard cubic meter. The fly ash can be periodically recovered after the dust-containing sewage is precipitated by the sedimentation tank, and the obvious energy-saving effect is achieved. The device can be suitable for one or more boilers using various fuels to remove dust. And has the advantages of compact structure, reliable performance, convenient operation, low one-time investment and quick response.
Description
Fig. 1. the dedusting energy-saving device schematic diagram
Fig. 2. the spray column schematic diagram
This dedusting energy-saving device is made up of spray column 2, settling tank 6, circulating pump 9, flue 1, smokejack 3, sewage conduct 4 etc.One end of flue 1 links to each other with the smoke input chamber 16 of spray column 2 by the bottom of spray column 2, and an end of sewage conduct 4 links to each other with the draining breast that drenches tower 2 of disputing, and two one-level sedimentation basins 5 of the other end and settling tank 6 link.Spray column 2 has two chambeies, one is smoke input chamber 16, one is smoke extraction chamber 15, in the exchange layer 14 a metal net curtain 10 of usefulness is arranged, the rule two-layer or two-layer above cast of discharging or positive hexahedron silica or cobblestone 11 on the net curtain 10, silica or cobblestone 11 porosity sum each other is more than or equal to total cross-sectional area of flue.The useful space sectional area that allows flue dust to pass through in the exchange layer 14 should be equal to or greater than total cross-sectional area of flue 11.Sparge pipe 13 is positioned at the top of silica, has hole for water spraying at the lower surface of tube wall along water (flow) direction.Varying aperture is that from entering the mouth 2 meters, the aperture is 3 millimeters.Hole count is 560, and from 2 meters to 3 meters, the aperture is 4 millimeters, and hole count is 280, and from 3 meters to 4 meters, the aperture is 5 millimeters, and hole count is 280.Sparge pipe 13 links to each other with circulating pump 9.Net 12 is equipped with on the top that on the top of the water pipe 13 of disputing is spray column 2.The smoke extraction chamber 15 of spray column 2 communicates with smokejack 3.The one-level sedimentation basin 5 of settling tank 6, second-level settling pond 7, clear water reserviors 8 have screen pack in order to filter flyash for being connected in series between the Chi Yuchi.
This dedusting energy-saving device as principle be mutually, the water that contains the alkali electroless medicine of being disputed out by the water hole of disputing on the sparge pipe 13 after circulating pump 9 pressurizations is sprayed on silica or the cobblestone 11, because silica or cobblestone 11 have good hydrophilicity, form water membrane on its surface.When the still inadequate ash-laden gas of burning enters the smoke input chamber 16 of spray column 2 via flue 1, and continue to rise by net curtain 10.When silica or cobblestone 11, grit in the flue dust is caught and is removed by moisture film, pernicious gas in the flue gas reacts with the alkali electroless medicine that adds in the entry, flue gas after being purified continues to move upward, during by screen cloth 12, in the flue gas as yet not the drop of the dust of Ex-all and harmful substance be filtered and remove.The flue gas that purifies enters smokejack 13 from smoke extraction chamber 15 and enters atmosphere.Dust-laden sewage enters settling tank 6 precipitations by the osculum of spray column 2 bottoms through sewage conduct 4, and the clear water of post precipitation is recycling after circulating pump 9 pressurizations, and the dust of precipitation is recycled.
The utility model advantage compared to existing technology is:
1. compact conformation, dependable performance, expense is low, instant effect.Several boilers can a shared playscript with stage directions device.
2. dust removing effects is obvious.Detect through environmental administration, efficiency of dust collection is more than 98%, for particle diameter greater than 10 Miao's rice dust dust removal efficiencies almost near 100%, the discharging blackness of exhaustion is 1 grade of Lin Geman.
3. energy-saving effect is obvious.Recoverable flyash was 6 cubic metres in 24 hours
Claims (5)
1. a coal-burning boiler dedusting energy-saving device is made up of spray column, settling tank, circulating pump, flue, smokejack, sewage conduct etc., it is characterized in that,
A. spray column respectively with flue, sewage conduct is connected, the other end of sewage conduct links to each other with settling tank;
B. the top of the flue mouth of spray column is provided with in order to purify the exchange layer of flue dust, and the top of handing-over layer is provided with sparge pipe, is equipped with on the top of sparge pipe in order to remove the screen cloth of the drop of carrying dust-laden or harmful substance in the gas secretly;
C. the exchange layer has a net curtain, is placed with the silica in order to the absorption flue dust on the net curtain;
2. dedusting energy-saving device according to claim 1 it is characterized in that the silica of arranging on the net curtain of said exchange layer has more than two layers, and porosity sum each other is more than or equal to total cross-sectional area of flue.
3. require 1 described dedusting energy-saving device according to power stripping, the lower surface that it is characterized in that said sparge pipe has along the water (flow) direction aperture and becomes big hole for water spraying in gradient.
4. dedusting energy-saving device according to claim 1 is characterized in that said silica is circle or limit number greater than the silica of five positive gengon.
5. according to claim 1 or 4 described dedusting energy-saving devices, it is characterized in that said silica can be a cobblestone.
