Abstract
The invention relates to a high-pressure water-mist venturi pipe assembly which can effectively solve the problem about cooling and dust removing in a dusty gas discharging process. The technical scheme is that the high-pressure water-mist venturi pipe assembly comprises a water tank, a high-pressure pump and a venturi pipe, wherein a water outlet of the water tank is connected with a water inlet of the high-pressure pump; a stainless steel pipe is mounted at a water outlet of the high-pressure pump; an outlet end of the stainless steel pipe extends into a straight pipe section of the venturi pipe, the diameter of the straight pipe section is smaller, and a high-pressure water-mist nozzle is mounted at the extending end part. The high-pressure water-mist venturi pipe assembly is novel and unique in structure, simple, reasonable, easy to produce, low in cost and low in water consumption, flue gas and water mist are combined to form large-particle fog drips falling down, the whole pipe can be the dust falling area, accordingly, the space resource is sufficiently utilized, the pipe is remarkably shortened, the cooling and dust removing effects are good, the use is convenient, and good social and economic benefits are achieved.
Description
Technical field
The present invention relates to cooling dust arrester, particularly a kind of heavy pressure fine spray Venturi.
Background technology
In recent years, along with the develop rapidly of China's economy, take coal as the energy resource consumption sustainable growth of main composition, be discharged into the flue dust in air and SO
2also increasing.According to statistics, within 1997, China's dirt discharge capacity reaches 1,873 ten thousand t, SO
2discharge capacity reaches 2,346 ten thousand t.Flue dust and SO
2cause serious atmosphere pollution, therefore, cost-effective technical measures must have been taked to control flue dust and SO
2deng the discharge capacity of pernicious gas.Wet scrubber is the very important gas purifying equipment of a class, and wherein, Venturi scrubber is most effective, and can be less than powder dust particle and the gaseous contaminant of 0-11 μm in order to remove particle diameter, efficiency of dust collection can reach 99%, and desulfuration efficiency can reach 90%.And it is cheap, structure simple (without movement parts), can process moist and corrosive gas.But its high capture rate for fine dusts and sulfur dioxide is is cost with provided energy and pressure loss, and therefore, its improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the present invention is just to provide a kind of heavy pressure fine spray Venturi, effectively can solve in dusty gas discharge process the problem of dedusting of lowering the temperature.
The technical scheme that the present invention solves is, a kind of heavy pressure fine spray Venturi, comprise water tank, high-pressure pump and Venturi, the delivery port of water tank is connected with the water inlet of high-pressure pump, the delivery port of high-pressure pump is equipped with stainless steel pipes, the port of export of stainless steel pipes stretches in the less straight length of the diameter of Venturi (also known as Venturi tube), and high-pressure water mist spray head is equipped with in the end stretched into.
Novel structure of the present invention is unique, advantages of simple, easily produces, and cost is low, water consumption is little, be combined into bulky grain droplet settle out by flue gas or with water mists, whole pipeline can be depositing dust region, make use of space resources fully, remarkable shortening pipeline, cooling good dedusting effect, easy to use, there is good Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is anatomical connectivity schematic diagram of the present invention (Venturi is cut open, and in figure, arrow 8 represents the flow direction of dusty gas).
Fig. 2 is the structural representation of Venturi of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Provided by Fig. 1-2, the present invention includes water tank, high-pressure pump and Venturi, the delivery port of water tank 4 is connected with the water inlet of high-pressure pump 5, stainless steel pipes 3 delivery port of high-pressure pump 5 is equipped with, the port of export of stainless steel pipes 3 stretches in the less straight length 12 of the diameter of Venturi 1, the end stretched into is equipped with high-pressure water mist spray head 2.
For ensureing result of use, described high-pressure water mist spray head 2 is by being fixed in Venturi 1 straight length 12, and the spray direction of high-pressure water mist spray head is consistent with the flow direction of dusty gas; Described high-pressure water mist spray head 2 to be the patent No. of applicant's earlier application be " 200610017940.7 " " super fine mist spraying head ", when pressure is 8-16MPa, mist particle diameter is 30-150 μm, and attachment dust particale performance is good;
Described Venturi 1 to be connected successively the tubulose integrative-structure formed by the upper transition 11 at two ends, straight length 12 and lower transition 13, the big opening end of upper transition 11 is connected with the outlet of admission line 7a, osculum end is connected with one end of straight length, the other end of straight length is connected with the osculum end of lower transition 13, and the big opening end of lower transition 13 is connected with the import of outlet pipe 7b;
Described water tank 4 is positioned at the top of high-pressure pump, makes compact overall structure, takes up room little, easy for installation;
Described high-pressure pump 5 is connected with controller 6, and described controller is prior art, for controlling the opening and closing of high-pressure pump.
When the present invention uses, unlatching high-pressure pump is started working, high-pressure water mist spray head 2 starts to spray water mists, flue gas (dusty gas) or other powders enter Venturi through admission line 7a, mix at straight length place with water mists, and mixed flue gas or other powders export from outlet pipe 7b, reach efficient mixing, water saving and energy-conservation, the effect of temperature with high efficiency dedusting, compared with prior art, the present invention has the following advantages:
1, efficient depositing dust: water mists and the soot dust granule in flue gas turbulent flow occur in straight length and lower transition region and mix rapidly, in conjunction with abundant, flue gas or other powders are combined into bulky grain droplet with water settle out, whole pipeline can be depositing dust region, make use of space resources fully, significantly shorten pipeline;
2, efficiently fall heat: water mists is enclosed in around flue gas or other powders, absorb the vaporization of its heat, can lower the temperature to material, there is the effect of good radiation-inhibiting heat;
3, safety and environmental protection: take water as inorganic agent, at high temperature can not decomposite harmful substance, environmentally safe, harmless to object of protection, on health of human body without impact;
4, reduce costs: inorganic agent of the present invention is common domestic water, inside can also reach self-cleaning function, water consumption is 1% of Water spray, saving water resource, reduce cost, Whole Equipment adopts stainless steel, extends the service life of equipment, has the advantages such as safe and efficient, energy-conserving and environment-protective, simple operation, low cost.
