Abstract
The invention discloses a removing device of fine dust particles and trace elements. The removing device of the fine dust particles and the trace elements comprises a liquid storage tank and a box body covering the liquid storage tank, wherein the box body is vertically divided into a waste gas pre-treatment chamber and a waste gas treatment chamber by a separation plate; the waste gas pre-treatment chamber and the liquid storage tank are separated through a horizontal separation plate which is horizontally arranged; a group of liquid column injection nozzles are distributed on the horizontal separation plate in an array; the waste gas pre-treatment chamber is internally provided with a group of flow field uniform distribution assemblies; a group of impinging stream filtering assemblies are vertically arranged at the lower side of the horizontal separation plate; the waste gas treatment chamber is separated from the liquid storage tank through a pore plate; a group of liquid column slurry spraying sections are arranged at the lower side of the pore plate; the waste gas treatment chamber is internally provided with a set of demisters; an air inlet is formed in the waste gas pre-treatment chamber; an air outlet is formed in the waste gas treatment chamber. The removing device of the fine dust particles and the trace elements, disclosed by the invention, is simple in structure, high in removing rate, low in operation cost, low in cost and small in occupying area.
Description
Technical field
The present invention relates to a kind of waste gas treatment equipment, particularly a kind of fine dust and trace element remove device.
Background technology
The dust and the waste gas that produce in the production processes such as coal-burning boiler, sintering machine, kiln contain multiple pollutant, and its discharging causes serious pollution to environment, such as sulfur dioxide, nitrogen oxide, fine dust PM10 and PM2.5, mercury, chromium, cadmium etc.; In the prior art, some desulfuring and denitrifying apparatus have played important function to the atmospheric environment of improving China, and fine dust PM10 and PM2.5, and the trace element pollution take mercury as representative also obtains the attention of China day by day, but, existing waste gas pollution control and treatment technology is limited to the place to go rate of fine dust and trace element, such as the spray column of routine, to the place to go rate of fine dust less than 8%.Dry electric precipitation device, its efficient can not surpass 30% yet, although then efficient is higher than dry electric precipitation device for electrostatic fabric filter and sack cleaner, produces easily filter bag and stop up, can't the operation of long time stability ground.Although and wet electrical dust precipitator efficient is higher, still have many technical problems to wait to solve.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the fine dust and the trace element that the invention discloses the wet-treating waste gas that the place to go rate is high, operating cost is low, cost is low remove device.
Technical scheme: the invention discloses a kind of fine dust and trace element and remove device, comprise, liquid storage tank, the casing of cover on liquid storage tank, casing vertically is divided into waste gas pretreatment chamber and exhaust-gas treatment chamber by dividing plate; Described waste gas pretreatment chamber and liquid storage tank separate by horizontally disposed diaphragm plate, and one group of liquid column-spraying nozzle of array arrangement on the diaphragm plate is provided with one group of uniform assembly in flow field in the waste gas pretreatment chamber, and the diaphragm plate downside vertically is provided with one group of percussion flow filter assemblies; Separate by dredging orifice plate and liquid storage tank described exhaust-gas treatment chamber, dredges the orifice plate downside and be provided with one group of fluid column slurries jet segment, and exhaust-gas treatment is indoor to be provided with one group of demister; Waste gas pretreatment chamber is provided with air inlet, and the exhaust-gas treatment chamber is provided with the gas outlet.
Described waste gas pretreatment chamber top is the exhaust gas diffusion stable section, it is the waste gas pretreatment section below the exhaust gas diffusion stable section, be fixed with the uniform assembly in flow field at waste gas pretreatment section middle part, waste gas pretreatment section bottom is provided with fluid column slurries pipeline, fluid column slurries pipeline is dendroid and distributes, and is fixed on the diaphragm plate by bearing.
Waste gas is entered by waste gas pretreatment chamber, process slurries in the ejection of liquid column-spraying nozzle, the uniform assembly in flow field that is comprised of ring flat-plate is evenly distributed air-flow, waste gas obtains cooling, dust obtains cohesion, for further strengthening this materializing procedure, uniform assembly has the percussion flow filter assemblies in the flow field, in this element, fine dust and trace element are removed fully, then, waste gas fully contacts with the processing slurries at fluid column slurries jet segment through the exhaust-gas treatment chamber, then pass through demister, discharged by exhaust outlet behind the removal drop.
Beneficial effect: fine dust disclosed by the invention and trace element remove device, and be simple in structure, and the place to go rate is high, operating cost is low, cost is low, floor space is little.
Description of drawings
Accompanying drawing 1 removes the structural representation of device for fine dust and trace element.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further explained.
The invention discloses a kind of fine dust and trace element and remove device, comprise, liquid storage tank 1, the casing of cover on liquid storage tank 1, casing vertically is divided into waste gas pretreatment chamber 2 and exhaust-gas treatment chamber 3 by dividing plate; Described waste gas pretreatment chamber 2 and liquid storage tank 1 are by horizontally disposed diaphragm plate 4 separately, one group of liquid column-spraying nozzle 5 of array arrangement on the diaphragm plate 4, be provided with one group of uniform assembly 6 in flow field in the waste gas pretreatment chamber 2, diaphragm plate 4 downsides vertically are provided with one group of percussion flow filter assemblies 7; Described exhaust-gas treatment chamber 3 is dredged orifice plate 8 downsides and is provided with one group of fluid column slurries jet segment 9 by dredging orifice plate 8 and liquid storage tank 1 separation, is provided with one group of demister 10 in the exhaust-gas treatment chamber 3; Waste gas pretreatment chamber 2 is provided with air inlet, and exhaust-gas treatment chamber 3 is provided with the gas outlet.
Described waste gas pretreatment chamber top is the exhaust gas diffusion stable section, it is the waste gas pretreatment section below the exhaust gas diffusion stable section, be fixed with the uniform assembly in flow field at waste gas pretreatment section middle part, waste gas pretreatment section bottom is provided with fluid column slurries pipeline, fluid column slurries pipeline is dendroid and distributes, and is fixed on the diaphragm plate by bearing.
Waste gas is entered by waste gas pretreatment chamber, process slurries in the ejection of liquid column-spraying nozzle, the uniform assembly in flow field that is comprised of ring flat-plate is evenly distributed air-flow, waste gas obtains cooling, dust obtains cohesion, for further strengthening this materializing procedure, uniform assembly has percussion flow filter assemblies 5 in the flow field, in this element, fine dust and trace element are removed fully, then, waste gas fully contacts with the processing slurries at fluid column slurries jet segment through the exhaust-gas treatment chamber, then pass through demister, discharged by exhaust outlet behind the removal drop.
The invention provides thinking and using method that a kind of fine dust and trace element remove device; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
