Description

The flow distributing and collecting device

Technical field

The present invention relates to a kind of flow distributing and collecting device, the particularly flow distributing and collecting device that uses of a supplied gas burner, combustion gas and air can fully be mixed through this flow distributing and collecting device, thereby can improve the efficiency of combustion of this combustion gas, reduce pollution.

Background technology

The health problem that oil smoke in the kitchen causes receives publicity just day by day, and the oil smoke gas in the kitchen makes the respiratory mucosa damage after being sucked by human body, and reduces immune function of human body.Oil smoke stimulates people's eyes, brings out angiocardiopathy.Interrelated data shows that in causing the lung cancer factor, cooking fume is to be only second to the hazards that " degree of depth smoking " smog arrives the respiratory tract deep.Yet the suggestion that prevents oil smoke gas that people provide all is to use and produces few high-quality soya-bean oil and the peanut oil of cooking fume, improves the kitchen ventilation condition, purifies air in kitchen etc.These suggestions all fail to solve the problem that flue gas produces this source.

The reason that oil smoke gas in the kitchen produces be since combustion gas fuel gas buring in gas-cooker get insufficient, thereby produce flue gas.Fuel gas buring is insufficient, has a strong impact on the efficiency of combustion of combustion gas, thus the time lengthening that makes culinary art, and the influence time that the people receives flue gas also just prolongs.Simultaneously, the oil of culinary art usefulness can decompose at a certain temperature, causes the generation of oil smoke, and the people has also received the influence of oil smoke in the influence that receives flue gas, and it is long to add cooking time, and people's health is had very big harm, and contaminated environment.

Gas-cooker, water heater, fireplace, kitchen cooking stove etc. are the great majority common household implements of family now.At present, traditional gas-cooker, water heater, fireplace or the employed burner of kitchen cooking stove have a variety of, these burners with liquefied petroleum gas, coal, natural gas or biogas as combustion gas to produce heat.

It is simply combustion gas to be lighted at burner port that burner employing the earliest has combustion method, and combustion gas and air do not mix, and the needed oxygen of fuel gas buring relies on from ambient air, to spread and gets.This is a kind of diffusion type combustion method.In combustion process, oxygen molecule can only be participated in burning through diffusion motion, and the intensity of burning depends primarily on the oxygen molecule diffusion velocity.The diffusion type combustion system is prone to igniting; Flameholding, but, only rely on the comparatively limited laminar flow diffusion of medium molecule diffusivity to needing oxygen more high heating value combustion gas commonly used such as natural gas, liquefied petroleum device etc.; Then be difficult to reach the purpose of completing combustion; And ignition temperature is on the low side, and the content of CO is higher, therefore unsuitable being applied among the domestic gas product.

Traditional burner sprays combustion gas through a gas nozzle from this gas nozzle, through the pressure effect of combustion gas, combustion gas mixes with air to form combustible gas.But this combustible gas can only be accomplished its basic burning, for this combustible gas of fully burning, must provide one the 22 air stream to mix once more with this combustible gas.In other words, if the air stream efficiency of supply is not high for the second time, this combustible gas can not completing combustion.Therefore, light this combustible gas after, will produce as NO and this this tail gas of CO.

Also have another kind of traditional burner, this burner combines with an infrared unit to carry out premixed with air.Therefore can cancel this second air stream.Such burner can improve the completing combustion degree of this combustible gas.But the thermic load of this burner will be limited, and just, if this burner is overheated, this burner will be closed.For this burner, heating control becomes subject matter.

Above-mentioned two kinds of burners all have a common defective, be exactly combustion gas be to mix with air through this fuel gas injection pressure.Therefore, do not provide special blender fully to mix with air to guarantee this combustion gas.The amount of the air that in other words, mixes with combustion gas is decided by this fuel gas injection pressure and is difficult to control.In case this combustion gas mixes with air, the speed of this combustible gas will significantly reduce.

In general, for traditional burner, the burning of uncontrollable fuel gas needs how many air (oxygen), also can't determine or guarantee the specific ratios of fuel gas and air (oxygen).In case external environment condition changes, like air themperature and concentration, combustion efficiency correspondingly is affected, and the result is exactly that the thermal efficiency is low, the waste gas that burning is slow and generation is too much.

Chinese patent 200720120452.9 discloses a kind of jet gas range, and wherein combustion gas can mix with air in a hollow mixing tube before burning in advance.An advantage of such gas-cooker is that an advantage of such gas-cooker is that it has higher combustion gas utilization rate and lower harmful gas emission; Another advantage is for further establishing flame control lid at this combustion head top, so the burning flame of combustion gas can cover the bottom of burning with direct contact pot in flame control, thereby reduced the thermal losses in the heat transfer process from flame to the pot.Yet this combustion gas is in this hollow mixing tube, to carry out nature with air to mix, and therefore, combustion gas still fails fully to mix with this combustion gas of abundant burning with air.On the other hand, no matter be the combustion gas that bottled combustion gas or pipeline transmit, it is all lower from the pressure that gas nozzle ejects.Therefore, the expulsion pressure that depends on this gas nozzle usually supplies mist to cover the burning of this kind combustion gas of burning in this flame control neither be very effective.

In other words, the length of this hollow mixing tube and compression stroke can not provide enough incorporation times fully to accomplish for combustion reaction for the abundant mixing of combustion gas and air.Therefore, be used for the very low and urgent need improvement of efficient of this conventional hybrid pipe that mixes naturally of air and combustion gas.

According to claim of the present invention and the disclosed content of specification, technical scheme of the present invention literary composition specific as follows is said.

As shown in Figure 1, Fig. 1 has disclosed a flow distributing and collecting device of one embodiment of the present invention, and it has a mixed flow path 10, and it is between the Di Qiang and an air stream outlet 11 of a sealing of this flow distributing and collecting device.End near this end wall of this mixed flow path 10 is an inlet end, and is the outlet side near an end of this air stream outlet 11.Inlet end at this mixed flow passage is provided with an air intake 12 and a fuel gas inlet 13; Supply air and combustion gas to get into this mixed flow path 10 from this air intake 12 and this fuel gas inlet 13 respectively; Form combustible gas in this mixed flow path 10 mixed flow, discharge this mixed flow path 10 from this air stream outlet 11 then.Preferably, this flow distributing and collecting device is one cylindrical.Correspondingly; This flow distributing and collecting device can be through this air intake 12 and this fuel gas inlet 13; Operationally connect a fuel gas source and an air source respectively, so combustion gas and air are directed the combustible gas that this mixed flow path 10 mixed flow into is formed on these air stream outlet 11 ejections.

This flow distributing and collecting device further comprises a cyclonic arrangement 20; This cyclonic arrangement 20 is supported in this mixed flow path 10, and wherein preferred the placing in this mixed flow passage 11 to separate this mixed flow path 10 with coaxial manner with this mixed flow path 10 of this cyclonic arrangement 20 is one second hybrid chamber 102 that is adjacent to one first hybrid chamber 101 of this air stream outlet 11 and is positioned at the inlet end of this flow distributing and collecting device.In other words, this first hybrid chamber 101 is positioned at the top of this cyclonic arrangement 20, and this second hybrid chamber 102 is positioned at the below of this cyclonic arrangement.Correspondingly, at first sprayed into this second hybrid chamber 102 from the combustion gas of fuel gas source with from the air of air source, wherein this cyclonic arrangement 10 is mixed the combustible gas that gets into this first hybrid chamber 101 to form well with combustion gas and air.According to a preferred embodiment of the invention, the size and the shape of the size of this cyclonic arrangement 20 and shape and this mixed flow path 10 are complementary, to such an extent as to this cyclonic arrangement 10 can be fit to be installed in this mixed flow path 10.Air passed through this air intake 12 and got into this second hybrid chamber 102, and combustion gas gets into this second hybrid chamber 102 through this fuel gas inlet 13.102 li of this second hybrid chambers, after combustion gas and the air mixed flow, flow to this cyclone and adorn 20.Through this cyclonic arrangement 20; This mixed flow gas that includes combustion gas and air is branched to this first hybrid chamber 101 mixed flow once more; Thereby improve the premix efficient of air and combustion gas, fully burn for it, practiced thrift the energy and reduced discharge of harmful gases for combustion gas provides enough oxygen.This mixed flow combustible gas of closing flows out from this air stream outlet 11 at last.

Shown in Fig. 3 A and Fig. 3 B, this cyclonic arrangement 20 comprises a mixer element 21 and a changed course device 23 that is supported in this mixed flow path 10.This mixer element 21 comprises that the confession that places in this mixed flow path 10 prolongs a calyptra 22 of combustion gas and Air mixing retention time.This calyptra 22 have wall 221 on one and on this periphery of wall 221 be defined on this in the wall 221 and this side wall 222 to a side wall 222, the one reservation caves 223 that extend below, wherein a bottom opening of this calyptra 22 is towards the bottom of this mixed flow passage.Therefore, the retention time of fuel gas mixture in this second hybrid chamber 102 can keep cave 223 through this and obtain prolonging.

Correspondingly, this mixer element 21 preferably places this mixed flow path 10 interior and coaxial with this columniform mixed flow path 10, and wherein this calyptra 22 preferably has the diameter littler than the interior diameter of this columniform mixed flow path 10.

This calyptra 22 further has the compartment of terrain and is the one group of port 224 that is formed at this side wall 222 radially; Therefore air and the combustion gas from this second hybrid chamber 102 can upwards flow to this reservation cave 223 further air mixture of confession and air, and discharging through this this port 224 that keeps this side wall 222 in cave 223 then should reservation cave 223.What deserves to be mentioned is that combustion gas and AIR MIXTURES in this reservation cave 223 have higher relatively pressure, so combustion gas and AIR MIXTURES can flow to this air stream outlet 11 through these port 224 these reservation caves 223 of discharge automatically.

This changed course device 23 can make from the combustion gas of this second hybrid chamber 102 and air and alter course in a spiral manner and be mixed into this first hybrid chamber 101, thereby improves combustion gas and Air mixing degree.Correspondingly; This changed course device 23 comprises one group of elongation and the director element 231 that tilts; This director element 231 outwards and the compartment of terrain protrude from this calyptra 22 this side wall 222 appearance and extend to the upper surface of wall 221 this on obliquely from the lower peripheral edge of this side wall 222, wherein one group of guiding groove 232 is formed at the air-flow that supplies between per two adjacent director elements 231 this gas-air mixture and alters course to form a up vortex-like gas-air mixture air-flow.Preferably, this director element 231 integratedly and be radially from the outer surface of this side wall 222 of this calyptra 22 and extend.

Correspondingly; Each this guiding groove 232 has a bottom opening that communicates with this second hybrid chamber 102 of the bottom that is formed at this calyptra 22; Open top that communicates with this first hybrid chamber 101 with the top that is formed at this calyptra 22; Therefore when combustion gas and air pass through tentatively mixing shape combustible gas this second hybrid chamber 102 in; Because this first and second hybrid chamber 101, the difference of the pressure between 102, this combustible gas sprays into this first hybrid chamber 101 with vortex-like mode from this second hybrid chamber 102 through this guiding groove 232.In other words, when this combustible gas is passed through this guiding groove 232, will further be mixed fully with the swirl shape mode.

In addition, this port 224 be formed at this calyptra 22 this side wall 222 to align so that communicate between this reservation cave 223 and this guiding groove 232 with this guiding groove 232 respectively.Therefore, this mixer element 21 can prolong combustion gas and the retention time of air in this second hybrid chamber 102 through this calyptra 22, and changes the airflow direction of combustible gas through this changed course device 23.Because the high pressure in this second hybrid chamber 102, this combustible gas will be respectively bottom through this port 224 and this guiding groove 232 direction that changes combustible gas supply combustion gas and air to mix well with the vortex-like stream that forms combustible gas.Well-known be this vortex-like air-flow can be in the confined space of limited incorporation time and this mixed flow path 10 air mixture and air effectively.

Replacedly, this calyptra 22 can be provided with independently with this changed course device 23 and supply to prolong the retention time of combustible gas and/or change airflow direction.For example, this director element 231 can contract to form airflow direction that this guiding groove 232 supplies to change these admixture of gas respectively to form the vortex-like mixture air-flow that makes progress in that the side wall of this calyptra 22 222 is recessed.Likewise; But this director element 231 one and inwardly extending in this mixed flow path 10, to form this guiding groove 232 from the inside wall of this mixed flow path 10; Therefore when combustion gas with air during through this guiding groove 232, this guiding groove 232 will change airflow direction and light preceding abundant air mixture and air to form the confession of vortex-like combustible gas stream.

Need that emphasis mentions be this calyptra 22 with this one guiding groove 232 can be together with the mixed flow maximizing efficiency of air and combustion gas.This mixer element 21 places installation and the structure thereof that will simplify this cyclonic arrangement 20 in this mixed flow path 10, thereby the production cost of flow distributing and collecting device of the present invention is minimized, and improves the completing combustion degree of combustion gas simultaneously.Therefore, through this cyclonic arrangement 20, combustion gas and air can carry out premixed well in this mixed flow path 10, so that this combustion gas completing combustion.

When air with after preliminary mixing of combustion gas process in this second hybrid chamber 102, flow to this cyclonic arrangement 20.When this preliminary mixed airflow that comprises combustion gas and air runs into this cyclonic arrangement 20 years, at first can be divided into two parts, one first preliminary mixed airflow and one second preliminary mixed airflow.This second preliminary mixed airflow is divided into the multiply mixed airflow by this group director element 231 of the changed course device 23 of this cyclonic arrangement 20.This multiply mixed airflow gets into each guiding groove 232 by this bottom notch of each guiding groove 232 of this changed course device 23 of this cyclonic arrangement 20 respectively, and by each guiding groove 232 respectively drainages to this first hybrid chamber 101.And this second preliminary mixed airflow flows to and should keep cave 223, and in this keeps cave 223 further air mixture and air.Flow out through this this group port that keeps this side wall 222 in cave 223 then and should keep cave 223; Flow into this corresponding respectively guiding groove 232 of this group port 224; Tentatively mix the mixed airflow of shunting out by first and mix again again with in this guiding groove 232; Make combustion gas and air in this guiding groove 232 further mix, flow into this first hybrid chamber 101 again with the swirl shape mode.

The mixed airflow that comprises air and combustion gas by this group guiding groove 232 is flowed out is strengthened mixed flow at this first hybrid chamber 101 with gyrate mode, so that air more fully mixes with combustion gas.In other words, this first hybrid chamber 101 provide mixed airflow that the space makes each shunting again mixed flow become a mixed airflow, thereby improve the mixed flow efficient of air and combustion gas.

What worth emphasis was mentioned is, when the pressure of this second hybrid chamber 102 of this mixed flow path 10 is enough big, combustion gas and air this second hybrid chamber 102 preliminary mix form preliminary mixed airflow after quilt sprayed to this cyclonic arrangement 20.This preliminary mixed airflow is by this group guiding groove 232 shuntings and changed course of this changed course device 23 of this cyclonic arrangement 20, and shape sprays to this first hybrid chamber 101 of this mixed flow path 10 to the swirl shape air-flow that rises.This cyclonic arrangement 20 forms the swirl shape air-flow that rises, and this swirl shape air-flow also reacts on this cyclonic arrangement 20, drives this cyclonic arrangement 20 rotations.That is to say that this preliminary mixed airflow forms the swirl shape air-flow that rises through this cyclonic arrangement 20, this swirl shape air-flow mixes in 101 li modes with the vortex dress of this first hybrid chamber.Will should be preliminary in mixed airflow shunting and the process that alters course at this group guiding groove 232 of this changed course device 23 of this cyclonic arrangement 20; After this preliminary mixed airflow was flowed into this group guiding groove 232 by branch, the inboard reaction force that produces of also continuous groove to this group guiding groove 232 was to change the position of this guiding groove 232.Because the channeling direction of this group guiding groove 232 all is consistent, is beneficial to form the gyrate ascending air of rising, so that in the inboard direction that produces one reaction force of the groove of this group guiding groove 232 also unanimity.And this moment, this cyclonic arrangement 20 also received the pressure effect that this preliminary mixed airflow sprays to this cyclonic arrangement 20.When the inboard cross force that produces of the groove of this group guiding groove 232 make a concerted effort to receive the frictional force of inboard wall of this gas channel 20 greater than this cyclonic arrangement 20 time, this cyclonic arrangement 20 begins rotation.When these airflow apparatus 20 rotations; It is to the shunting of this preliminary mixed airflow; Changed course; The efficient that forms the swirl shape air-flow that rises improves greatly, and has also been improved greatly in this preliminary mixed airflow mixing efficiency through this cyclonic arrangement 20 time, thereby has also improved the mixing efficiency of first hybrid chamber 101 indirectly.

What deserves to be mentioned is; A plurality of these cyclonic arrangement 20 can be set in this mixed flow path 10 according to actual needs; This mixed flow path 10 is divided into a plurality of sub-hybrid chambers, thereby then can gets this air and combustion gas mixing more abundant through shunting, mixed flow repeatedly through the mist that comprises air and combustion gas of this mixed flow path 10.

This flow distributing and collecting device further comprises a part flow arrangement 30, and this part flow arrangement 30 is installed on these air stream outlet 11 places of this flow distributing and collecting device suitably and securely, for shunting this combustible gas that comprises air and combustion gas from this air stream outlet ejection.

As shown in Figure 4; This part flow arrangement 30 preferably has a head 31 and a lotus root and meets portion 32 and supply securely this part flow arrangement 30 to be installed on this air stream outlet 11; Wherein this part flow arrangement 30 can through install or rotatably connected mode be installed on this top outlet 12 securely, for example this lotus root connects corresponding threaded portion (figure is last not to be drawn) on the inner peripheral wall of external screw-thread part and this mixed flow path 10 of portion 22.

Correspondingly, this head 31 of this part flow arrangement 30 has defined a upper surface 311 and a lower surface 312, and wherein this head 31 is suitable for covering this air stream outlet 11 of this mixed flow path 10.This part flow arrangement 30 further has the one group of perforation openings 313 that is preferably formed in this head 31; And extend to this surface 312 from this upper surface 311 and supply to be connected with this mixed flow path 10, with mean allocation pass through this air stream outlet 11 through well-mixed combustible gas.Therefore, when this combustible gas when this air stream outlet 11, this combustible gas through this perforation openings 313 to spray this flow distributing and collecting device.In addition, each this perforation openings 313 preferably has a taper first openend 3131 that is formed at this upper surface 311, and wherein the diameter of this first openend 3131 increases to form wide opening at this upper surface 311 gradually.

With respect to this mixed flow path 10; First this perforation openings 313 is that the passage of an elongation and the compartment of terrain that preferably is parallel to each other extend to this lower surface 312 from this upper surface 211 of this head 31, thereby forms this first openend 3131 that has the broad opening and relative one second openend 3132 that is positioned at this lower surface 312 at these upper surface 311 places.Therefore; This perforation openings 213 has a narrower passage 3133 that extends from the taper of this broad first openend 3131, to such an extent as to can increase this ejection pressure through well-mixed combustible gas by these part flow arrangement 30 ejections through this narrower passage 3133.

This perforation openings 313 can be fifty-fifty and is these head 31 places that are positioned at this part flow arrangement 30 radially and supply the air-flow on this upper surface 311 of mean allocation, wherein this head 31 further the center of this head 31 have a core and around this in part one around part.This lower surface 312 that is positioned at this core contracts with the air-flow on this upper surface 211 that forms a center cavity 314 confession gatherings and enhancing core at this lower surface 312 to fovea superior.

Be positioned at this first this second openend 3132 around this perforation openings 313 of part can further have a relative broad in this lower surface 312 opening.In other words; Be positioned at this this second openend 3132 and preferably have opposite taper around this perforation openings 313 of part; This opposite taper increases this perforation openings 313 diameters gradually downwards, and forms the opening of relative broad at this lower surface 312, and therefore being positioned at this this perforation openings 313 around part can be with the gaseous mixture scale of construction maximization of passing this head 31; Simultaneously, when the combustible gas of mixing pass this perforation openings 213 than narrow passage 3133 time can improve expulsion pressure.

What deserves to be mentioned is that this upper surface 311 of this part flow arrangement 30 can supply flame to burn above that.That is to say that flow distributing and collecting device of the present invention is suitable for collaborative arbitrary existence igniting set and supplies to light the combustible gas through these part flow arrangement 30 ejections of flow distributing and collecting device of the present invention.For example, this igniting set can produce flame for a piezoelectric unit is used to light this combustible gas.Flame can burn on this upper surface 311 of this part flow arrangement 30.

The combustible gas that comprises air and combustion gas in this first hybrid chamber 101 through after the abundant mixed flow; Formation can supply clean-burning combustible gas; This combustible gas at first is divided into two parts through this part flow arrangement 30 time, one first combustible gas stream and one second combustible gas stream.This first combustible gas stream is assembled at this center cavity 314; Shunted by a plurality of this perforation openings 313 of the core of this upper surface 311 of these center cavity 214 pairing these part flow arrangements 30 again, and from a plurality of these perforation openings 313 these part flow arrangements 30 of ejection of the core of this upper surface 311.If this first combustible gas stream sprays from a plurality of these perforation openings 313 of the core of this part flow arrangement 30, and is lighted, this that then is ejected first combustible gas is formed on the flame of centre of these part flow arrangement 30 burnings.This second combustible gas stream then is split into multiply combustible gas stream by a plurality of these perforation openings 313 around this center cavity 314; Through each perforation openings 313 mean allocation and be ejected into the non-central part of this upper surface 311 of this part flow arrangement 30, thereby make that this combustible gas of being sprayed can be in the non-central partial combustion of this upper surface 311 of this part flow arrangement 30.It is to be noted; When combustible gas these second openend, 3132 these perforation openings 313 of entering from this perforation openings 313; Then through this narrower passage 3133 of this perforation openings 313, be ejected into the upper surface 311 of this part flow arrangement 30 again from this first openend 3131 of this perforation openings 313.Because this perforation openings 313 has this narrower passage 3133, so that when this this narrower passage 3133 through this perforation openings 213 of combustible gas, can improve this expulsion pressure, thereby in the degree of heat of this part flow arrangement 30 places raising flame.

What need mention especially is, this center cavity 314 can prevent flame when these upper surface 311 burnings of this part flow arrangement 30, and flame extinguishes in the process little by big commentaries on classics.As shown in Figure 2; This first combustible gas stream is compared with the two or two combustible gas stream; This first combustible gas stream needs through this center cavity 314 just by these center cavity 314 pairing a plurality of these perforation openings 313 shuntings of this part flow arrangement 30, pressurization ejection.This second combustible gas stream is then directly by a plurality of these perforation openings 313 shuntings around this center cavity 314, pressurization ejection.That is to say that the flowing velocity of this second combustible gas stream is faster slightly than the flowing velocity of this first combustible gas stream.In other words, this center cavity 314 has played the slow of this first combustible gas stream, the effect of delay.When at the upper surface burned flame of this part flow arrangement 30 from large to small the time; Particularly be transformed into and have only flame of centre when burning; Combustion gas and air can tentatively mix through this air intake 12 and this second hybrid chamber 102 that this fuel gas inlet 13 gets into this mixed flow path 10 to be lower than original speed, thereby cause the combustible gas of preliminary mixing also to reduce through the speed that this cyclonic arrangement 20 gets into first hybrid chamber 101 again.Originally combustion gas and the air at first hybrid chamber 101 of this mixed flow path 10 then tentatively mixes with original speed, through this cyclonic arrangement 20, gets into this first hybrid chamber 101 again, then from these part flow arrangement 30 ejections.That is to say that the combustible gas that former this part flow arrangement 30 of combustible gas ejection slows down finally flows out and has a time difference between this part flow arrangement 30.If in this time difference, there is not combustible gas to flow out from this part flow arrangement 30, then upper surface 311 burned flames at this part flow arrangement 30 will extinguish, thereby cause gas leakage.And 314 pairs of these first fuel gas stream of this center cavity be detained and slow effect; Thereby cause in this time difference; Also continue to have combustible gas to flow out from this part flow arrangement 30; Thereby guarantee that flame continues these upper surface 311 burnings at this part flow arrangement 30, prevent that flame is little and cause that the situation of fray-out of flame takes place by big commentaries on classics.
