Abstract
The invention provides an air purifying method using a multistrand convergence water spraying jet circulation system and a same direction air flow system in a high speed mixing machine in a mixing tube to collect floating impurities in air. The invention changes the traditional way of improving purification efficiency at the cost of increasing windage or decreasing wind speed in the existing air purifying technique. High speed water flow and high speed air flow mix in the mixing tube and collect floating impurities in air, and the purification efficiency increases with the increase of the velocity of flow.
Description
The present invention proposes a kind of multiply of utilizing and converge water spray the jet circulatory system and the high speed blending mechanism of equidirectional air flow system in mixing tube, belong to the environmental protection field in order to the air purification method of floating impurity in the traps air.
Air cleaning is to take suitable method with the showy impurity that mixes in the air, thereby makes it to break away from the processing procedure of recovering air purity as captures such as dust, microorganism, mist of oil, coating cloud, smog from air.Air cleaning is the important content of environmental protection, and closely bound up with people's life and health, the degree of purification of air also concerns the reliability of product quality and research and production in a lot of industry and scientific research field.So the research of air purifying process is also extremely paid attention to.
Existing air purifying process kind is a lot, is divided into mechanical filter usually according to the difference to the impurity capture mode of floating, Electrostatic Absorption, and water-bath washing and water smoke spray cleaning etc. are different classes of.Various capture modes respectively have pluses and minuses.
The mechanical filter technology has cyclone separator and the separation chamber, labyrinth that adopts the inertial separation principle, and the cloth bag dust removal by filtration that adopts the dielectric impedance work principle of filter and filter core purification etc. are also arranged.Mechanical filter clarifier advantage is simple in structure, so wide application easy for installation, shortcoming is that the purification precision is not high, can not purify pollutants such as fine particle and mist of oil.And, purify precision and be directly proportional with equipment resistance.Must overcome than big filter machinery and mechanical resistance for improving depuration quality, require blower fan to have higher blast and higher-wattage.So there is the high and low problem of purification efficiency of energy consumption in mechanical filter formula air purifier.
The Electrostatic Absorption clarifier compares that mechanical filter clarifier resistance is little, and energy consumption is little, and treating capacity is big, is widely used in the depositing dust of large-sized boiler burnt gas, also is used for fume purifying.But it has three shortcomings, the one, and the wind speed during through the static pole plate can not be too high, otherwise influence purification efficiency, so common sectional area of electrostatic purifier and volume are very big; The 2nd, the plant maintenance cleaning work is heavy.Particularly the cleaning of the pole plate of smoke purifier is especially difficult; The 3rd, in a single day contaminated thing accumulation of job insecurity, pole plate and covering, purification efficiency can obviously descend; In addition, static purification is used for will paying special attention to when oil smoke is handled fire-proof and explosion-proof.The Electrostatic Absorption clarifier mainly is problem, the problem of even running and the problem of safe operation that has the regular maintenance cleaning
The water-bath washing clarifier is that air is fed in the water, and hydrophilic air plankton and solid impurity are replaced in the water.But the volume of underwater bubble has hindered the contact of gas-liquid two-phase material, and is invalid substantially to not hydrophilic impurity.Can only be as the prefiltration of high concentration dust laden air.
The water smoke spray cleaning is with water atomisation landing, air from bottom to top with the water droplet move toward one another of landing.Advantage is to purify the precision height, and is effective to hydrophilic impurity absorption, is generally used in the chemical-process, as spray absorber etc.Shortcoming is that relative velocity can not be high, and the equipment bulky complex is difficult to be applied to general purpose air cleaning.
Though more than several clarifier capture modes have nothing in common with each other, they still have a common character (shortcoming), are exactly that the purification of air captures all air is flowed applied resistance or limited flow velocity by bulked volume more or less of mode.This disagrees with the hope that our high efficiency purifies air undoubtedly,
The objective of the invention is to propose a kind of air purification method that utilizes multiply to converge floating impurity in the water spray jet circulatory system and the high speed blending mechanism traps air of equidirectional air flow system in mixing tube.The water jet direction is consistent with air-flow direction to be the important feature that it is different from other prior art air purifiers.It is fast more that it shows as fluid velocity, and it is high more that mass transfer passes the energy response intensity, and clean-up effect is good more.This is consistent with the hope that we pursue the efficient high-speed processing.
The air purification method of air purification method contrast prior art proposed by the invention has following several respects advantage:
1) energy consumption is little.Because air velocity and purification efficiency be contradiction not, the moving system channel of air purification method hollow air-flow of the present invention is unimpeded, even has equidirectional the flowing of water jet to play the effect of further reduction air flow resistance.Energy consumption of the present invention is because internal drag is very little, and under equal air-treatment amount condition, power consumption values is lower than other air purification methods.
2) volume is little.Because air velocity and purification efficiency be contradiction not, purifier inner air flow velocity is higher than other existing air purification methods.Device of the present invention, when the air-treatment amount was identical with purification efficiency, volume obviously reduced.
3) the capture content is extensive, the purification efficiency height.Water is well to capture medium, except that water-fast gas, swims in airborne solid particle and liquid particles, no matter oiliness and water-based molecule group also no matter granular size all can efficiently capture.Add a certain amount of disinfectant in the water, but the sterilizing and purifying air.
4) device operates steadily.Aqueous medium is received ability to the culvert of pollution medium and is higher than other media, and long-time use can not increase air drag, the systematic parameter all-the-time stable.
5) regular maintenance is easy.Regularly changing water is only routine work, and the processing of water is with reference to the processing method of other sewage or according to related standards.
Comprise the air operational system of open loop and the water circular flow system of closed loop in the air purification method proposed by the invention.Two operational systems are positioned in the middle of the vessel shell, and the blending in the same way of two-phase flow operational system is finished with separating in mixing tube space and shell space.Floating solid and liquid particles and the water-soluble chemical gas impurity of part have been stayed in the water in the air, purifying air from air outlet row to atmosphere after the separation.It all is initiatively jet motion that water jet and air are flowing in the mixing tube, is different from the branch that injector has principal and subordinate's jet, and the core component mixing tube of air purification method of the present invention and two phase flow blending mechanism are to be the special designs of purpose to purify air.
For strengthening the capture dynamics of water, need current to resolve into more more tiny particle waters, particular design of the present invention the porous convergence water spout, the thick easier decomposition of water jet of water spray jet ratio sub-thread that multiply is thinner, multiply water spray jet converges collision near parallel tube segments and diffusion pipeline section intersection in addition, strengthen the decomposition mechanism of water jet more, helped forming the so-called foam hose stream that the extremely strong aqueous vapor of trapping ability is evenly distributed.Convergent point design near parallel tube segments and diffusion pipeline section intersection be because of, influence trapping ability if convergent point can make more water droplets touch wall too early in advance owing to the space is narrow and small, the foam hose stream range that forms after converging shorten and can weaken trapping ability equally if convergent point is delayed meeting.
Mixing tube is the important place of moving air and the abundant blending of water of flowing, and it is designed to four sections especially, promptly shrinks entrance, parallel tube segments, diffusion pipeline section and bend loss, and each section has main effect separately.Shrink entrance and conveniently receive air and quicken it, the entrance shape also with multi-strand flow entad convergence angle match; Parallel tube segments provides one section small space, the current of certain speed under the turbulent fluctuation diffusion in addition between the two phase flow speed difference tear effect, current are become the stream of liquid droplets of dispersion by Continuous Flow.In the mixing tube parallel tube segments, air velocity is far above flow rate of water flow usually, and this also is one of main distinction with fluid entrainment pump; The diffusion pipeline section provides the space environment that enlarges, air stream certainly leads to field of turbulent flow, the multi-strand flow convergent point of the present invention's design is just in the diffuser initial end, penetrate the stream of liquid droplets of coming with convergence angle separately and collide further differentiation drop herein, simultaneously under the stirring of air turbulent fluctuation field with the abundant blending of air-flow, synthesize the so-called foam hose stream that one aqueous vapor is evenly distributed; The resistance minimum that terminal tangent plane transition of bend loss and anemostat thereby convection cell produce, bend loss provides tangential adherent sports center of sliding for foam hose stream, water is condensed into current outflow mixing tube again and falls into the pond together with adherent the sliding of the impurity that is captured under effect of inertia, and the air of purification then overflows from foam and leaves mixing tube.
For guaranteeing water circular flow system operate as normal, container bottom is provided with particulate filter, enters water pump and water spout to avoid larger particles.
Further specify the course of work of air purification method of the present invention below in conjunction with accompanying drawing.
There are two systems of free fate row system and water circular flow system to work simultaneously in the purification method of the present invention.
The air operational system is made up of air inlet (1), air supply line (2), mixing tube contraction entrance (3), mixing tube parallel tube segments (4), mixing tube diffusion pipeline section (5), mixing tube bend loss (6), vessel shell (12) and air outlet (7) etc., and air inlet (1) and air outlet (7) have at least one to be the power mouth that blower fan has been installed.Vessel shell (12) is not only the closed shell that the air operational system and the multiply water jet circulatory system are installed, and also is the water receptacle of recirculated water.Mixing tube and air operational system are positioned on the water surface.

The concise and to the point process of air operational system work is: extraneous air is delivered to the contraction section inlet (3) of mixing tube by air-supply pipeline (2) by air inlet (1) under fan action, appropriateness is quickened the back enters mixing tube by the parallel tube segments (4) of mixing tube diffusion pipeline section (5), because changing, spatial expansion forms the turbulent region, converge the water spray jet in this section and multiply and form the extremely strong so-called foam hose stream of capture power, foam hose stream when the bend loss (6) by mixing tube because the effect of inertia force and adherent sliding, air is sloughed impurity and is overflowed from foam, purifies air further to discharge from air outlet after the dehydration above liquid level.
The concise and to the point process of water circular flow system works is: the recirculated water (8) in the pond, vessel shell (12) bottom is delivered to porous convergence formula water spout (11) through water pump (9) pressurization by water under high pressure pipeline (10), the multiply of water spout ejection converges the water spray jet and air stream together enters parallel tube segments by mixing tube contraction entrance, and current resolve into the so-called stream of liquid droplets of being made up of fine liquid particles in parallel tube segments and windage.Near multiply drip jet intersection parallel tube segments and diffusion pipeline section intersection converges collision, the special fluidised form in air turbulence district in addition, make hybrid reaction reach a climax, current are torn into the foam-like jet that droplet and air blending form one uniform gas-liquid distribution, have very high-speed foam hose stream at bend loss and be thrown toward tube wall, water reverts to liquid form again together with impurity and flows back in the pond of container bottom.Water-fast purifying air overflowed.Water recycles after water body particulate filter (13) filters.
