The beneficial effects of the utility model are:
This coal smoke desulfurization and dust removal device adopts the design of Venturi tube+waveform baffle plate, Venturi tube upwards sprays sulphur-containing exhaust gas, and waste gas is sprayed onto waveform baffle plate and turns around, and runs into the cleaning solution water smoke moved upward, thus make sulphur-containing exhaust gas repeat to contact with cleaning solution water smoke, make desulfuration efficiency higher.
In settling tank, division box is set, settling tank is divided into clear water zone and contraminated zone by division box, and division box serves the effect of precipitation waste residue, and clear water after precipitation sends into the spray equipment of water curtain dedusting by water circulating pump, recycle water resource like this, cost-saving.
Connecting pipe between desulfurization chamber and water curtain dedusting chamber is gas compression passage, is provided with multiple oval projection, both can accelerates gas flow rate, can prevent dust accretions again, blocking pipe, reach the effect of self-cleaning in passage.
This coal smoke desulfurization and dust removal device is provided with deflection plate demister, the dust particle that small part can be enable not condense with water smoke makes the abundant and water smoke of this part dust condense under the effect of deflection plate, and again filter, such dust removing effects is better, and owing to employing the deflector at angle of inclination, the liquid under demister drippage tumbles at deflector lowest part, is connected to washing liquid lines by pipeline, cleaning solution is diluted, is not easy blocking pipe.
This device structure is tight, easy for installation, and safeguard simple, efficiency of dust collection is high.
Accompanying drawing explanation
Fig. 1 is this coal smoke desulfurization and dust removal device structural representation.
Fig. 2 is coal smoke desulfurization and dust removal device water curtain dedusting cavity configuration practicality figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, can implements according to this with reference to description word to make those skilled in the art.
A kind of coal smoke desulfurization and dust removal device, comprise the housing 1 that an inside is cavity, described housing central section is provided with air inlet 2, described case top is provided with gas outlet 3, deflection plate demister 9 is provided with below described gas outlet, dividing plate 4 is provided with in described housing, enclosure interior is separated into two cavitys in left and right by described dividing plate 4, be respectively desulfurization chamber 5 and water curtain dedusting chamber 6, and communicated by pipeline in the middle part of described desulfurization chamber with between water curtain dedusting chamber, described air inlet 2 is positioned at described desulfurization chamber 5 place, described air inlet 2 is in parallel by admission line 21 with the multiple Venturi tubes 51 in described desulfurization chamber, the Venturi tube of described Venturi tube to be flow velocity be 10-25m/s, waveform plate washer 52 is fixed with above described Venturi tube 51, described Venturi tube is provided with a cleaning solution shower nozzle 53 between any two, described cleaning solution shower nozzle 53 parallel connection access cleaning solution passage 531, described cleaning solution is the aqueous solution of lime stone, described Venturi tube 51 and cleaning solution shower nozzle 53 direction are all vertically upward, described desulfurization lower box part is provided with settling tank 54, division box 541 is arranged in described settling tank 54, settling tank is divided into contraminated zone and clear water zone by described division box, described water curtain dedusting chamber comprises spray equipment 61, water curtain baffle plate 62 and waste liquid pool 63, described spray equipment 61 is communicated with by water circulating pump 8 with the clear water zone of settling tank.
