Description

Flow distributing and collecting device

Technical field

The present invention relates to a kind of flow distributing and collecting device, the flow distributing and collecting device of a particularly supplied gas burner use, combustion gas and air can be thoroughly mixed by this flow distributing and collecting device, thus can improve the efficiency of combustion of this combustion gas, decreasing pollution.

Background technology

The health problem that oil smoke in kitchen causes receives publicity just day by day, and the cooking fume in kitchen makes respiratory mucosa damage after being sucked by human body, and reduces immune function of human body.Oil smoke stimulates the eyes of people, brings out angiocardiopathy.Interrelated data shows, and is causing in lung cancer factor, and cooking fume is only second to the hazards that " degree of depth smoking " smog arrives respiratory tract deep.But the suggestion of cooking fume that prevents that people provide is all use to produce the few high-quality soya-bean oil of cooking fume and peanut oil, improves kitchen ventilation condition, purifying air in kitchen etc.These suggestions all could not solve the problem that flue gas produces this source.

Cooking fume Producing reason in kitchen is because combustion gas fuel gas buring in gas-cooker obtains insufficient, thus produces flue gas.Fuel gas buring is insufficient, has a strong impact on the efficiency of combustion of combustion gas, thus makes the time lengthening of culinary art, and the influence time that people is subject to flue gas also just extends.Meanwhile, the oil of culinary art can decompose at a certain temperature, and cause the generation of oil smoke, people, while the impact being subject to flue gas, also receives the impact of oil smoke, and it is long to add cooking time, has very large harm to the health of people, and contaminated environment.

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

Burner the earliest adopts has combustion method to be combustion gas lighted at burner port simply, and combustion gas and air do not mix, and the oxygen required for fuel gas buring relies on to spread from ambient air and gets.This is a kind of diffusion type combustion method.In combustion, oxygen molecule can only participate in burning by diffusion motion, and the intensity of burning depends primarily on oxygen molecule diffusion velocity.Diffusion type combustion system is easily lighted a fire, flameholding, but to the conventional high heating value combustion gas needing oxygen more as natural gas, liquefied petroleum device etc., only rely on the laminar flow diffusion that medium molecule diffusivity is comparatively limited, then be difficult to reach the object of burning completely, and ignition temperature is on the low side, the content of CO is higher, is therefore not suitable for being applied in domestic gas products.

Combustion gas is sprayed from this gas nozzle by a gas nozzle by traditional burner, and by the pressure effect of combustion gas, combustion gas mixes to form combustible gas with air.But this combustible gas can only complete its basic burning, in order to this combustible gas of Thorough combustion, one the 22 air stream must be provided again to mix with this combustible gas.In other words, if this second time air stream efficiency of supply is not high, this combustible gas can not be burnt completely.Therefore, after lighting this combustible gas, will produce as this this tail gas of NO and CO.

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

Above-mentioned two kinds of burners all have a common defect, be exactly combustion gas are mixed with air by this fuel gas injection pressure.Therefore, do not provide special blender to ensure that this combustion gas fully mixes with air.In other words, the amount of carrying out the air mixed with combustion gas is decided by this fuel gas injection pressure and is difficult to control.Once this combustion gas mixes with air, the speed of this combustible gas will greatly reduce.

In general, for traditional burner, the burning of uncontrollable fuel gas needs how many air (oxygen), also cannot determine or ensure the specific ratios of fuel gas and air (oxygen).Once external environment condition changes, as air themperature and concentration, combustion efficiency is correspondingly affected, and result is exactly that the thermal efficiency is low, and burning is slow and produce too much waste gas.

Chinese patent 200720120452.9 has disclosed a kind of jet gas range, and wherein combustion gas can mix with air in advance before combustion in a hollow mixing tube.An advantage of such gas-cooker is an advantage of such gas-cooker is that it has higher combustion gas utilization rate and lower harmful gas emission; Another advantage controls lid for establishing a flame further at this combustion head top, and the burning flame of therefore combustion gas can control to cover burning with the bottom directly contacting pot at flame, thus decreases the thermal losses in the heat transfer process from flame to pot.But this combustion gas carries out nature with air to mix in this hollow mixing tube, therefore, combustion gas still fails to carry out with air fully mixing with this combustion gas of Thorough combustion.On the other hand, no matter be the combustion gas that bottled gas or pipeline transmit, its pressure ejected from gas nozzle is all lower.Therefore, the expulsion pressure usually depending on this gas nozzle controls to cover the burning of this kind of combustion gas of burning for mist at this flame 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 complete for combustion reaction for the abundant mixing of combustion gas and air.Therefore, very low for the efficiency of this conventional hybrid pipe of mixing naturally of air and combustion gas and be badly in need of improving.

Detailed description of the invention

According to the content disclosed in claim of the present invention and description, described in technical scheme of the present invention literary composition specific as follows.

As shown in Figure 1, Fig. 1 discloses a flow distributing and collecting device of one embodiment of the present invention, and it has a mixed flow path 10, between its Di Qiang closed at this flow distributing and collecting device and an air stream outlet 11.One end near this end wall of this mixed flow path 10 is inlet end, and is outlet side near one end of this air stream outlet 11.The inlet end of this mixed flow passage is provided with air intake 12 and a fuel gas inlet 13, this mixed flow path 10 is entered from this air intake 12 and this fuel gas inlet 13 respectively for air and combustion gas, form combustible gas in this mixed flow path 10 mixed flow, then discharge this mixed flow path 10 from this air stream outlet 11.Preferably, this flow distributing and collecting device is one cylindrical.Correspondingly, this flow distributing and collecting device is by this air intake 12 and this fuel gas inlet 13, operationally connect a fuel gas source and an air-source respectively, therefore combustion gas and air are guided into this mixed flow path 10 mixed flow and are formed in the combustible gas that this air stream outlet 11 sprays.

This flow distributing and collecting device comprises a cyclonic arrangement 20 further, this cyclonic arrangement 20 is supported in this mixed flow path 10, and wherein this cyclonic arrangement 20 is preferably placed in this mixed flow passage 11 with one second hybrid chamber 102 of inlet end that to separate this mixed flow path 10 be one first hybrid chamber 101 that is adjacent to this air stream outlet 11 be positioned at this flow distributing and collecting device with coaxial manner with this mixed flow path 10.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, first the combustion gas from fuel gas source and the air from air-source are injected into this second hybrid chamber 102, and wherein combustion gas and air are carried out mixing to be formed the combustible gas entering this first hybrid chamber 101 by this cyclonic arrangement 10 well.According to a preferred embodiment of the invention, the size and shape of this cyclonic arrangement 20 and the size of this mixed flow path 10 and mating shapes, to such an extent as to this cyclonic arrangement 10 can be applicable to being arranged in this mixed flow path 10.Air passed through this air intake 12 and entered this second hybrid chamber 102, and combustion gas enters this second hybrid chamber 102 through this fuel gas inlet 13.In this second hybrid chamber 102, after combustion gas and air mixed flow, flow to this cyclone and fill 20.Through this cyclonic arrangement 20, this mixed flow gas including combustion gas and air is branched to this first hybrid chamber 101 mixed flow again, thus improve the premix efficiency of air and combustion gas, for combustion gas provides enough oxygen for its Thorough combustion, save the discharge of the energy and minimizing pernicious gas.The combustible gas that finally this mixed flow is closed flows out from this air stream outlet 11.

As shown in Figure 3 A and Figure 3 B, this cyclonic arrangement 20 comprises mixer element 21 and the change course device 23 be supported in this mixed flow path 10.This mixer element 21 comprises the calyptra 22 supplying the mixing retention time extending combustion gas and air be placed in this mixed flow path 10.This calyptra 22 has wall 221 on one and retains cave 223 from the periphery of wall on this 221 to a side wall 222, of downward-extension and is defined on this in wall 221 and this side wall 222, and 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 is extended by this reservation cave 223.

Correspondingly, this mixer element 21 to be preferably placed in this mixed flow path 10 and coaxial with this columniform mixed flow path 10, and wherein this calyptra 22 preferably has the little diameter of the interior diameter of mixed flow path 10 more columniform than this.

This calyptra 22 has compartment of terrain further and is radially formed at one group of port 224 of this side wall 222, therefore upwards can flow to this reservation cave 223 for further air mixture and air from the air of this second hybrid chamber 102 and combustion gas, then discharge this reservation cave 223 by this port 224 of this side wall 222 in this reservation cave 223.It is worth mentioning that the mixture of combustion gas in this reservation cave 223 and air has relatively high pressure, therefore the mixture of combustion gas and air automatically can be discharged this reservation cave 223 by this port 224 and be flowed to this air stream outlet 11.

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

Correspondingly, each this guiding groove 232 has the bottom opening communicated with this second hybrid chamber 102 of the bottom being formed at this calyptra 22, with the open top communicated with this first hybrid chamber 101 at top being formed at this calyptra 22, therefore when combustion gas and air mix shape combustible gas through preliminary in this second hybrid chamber 102, because the pressure between this first and second hybrid chamber 101,102 is different, this combustible gas sprays into this first hybrid chamber 101 in vortex-like mode from this second hybrid chamber 102 by this guiding groove 232.In other words, when this combustible gas is by this guiding groove 232, will be mixed fully further in swirl shape mode.

In addition, this port 224 is formed at this side wall 222 of this calyptra 22 to align with this guiding groove 232 respectively to make to communicate between this reservation cave 223 and this guiding groove 232.Therefore, this mixer element 21 extends combustion gas and the retention time of air in this second hybrid chamber 102 by this calyptra 22, and is changed the airflow direction of combustible gas by this change course device 23.Due to the high pressure in this second hybrid chamber 102, the direction that the bottom respectively by this port 224 and this guiding groove 232 is changed combustible gas by this combustible gas mixes for combustion gas and air well with the vortex-like stream forming combustible gas.It is well known that this vortex-like air-flow can in the confined space of limited incorporation time and this mixed flow path 10 air mixture and air effectively.

Alternatively, this calyptra 22 and this change course device 23 can be arranged independently for extending the retention time of combustible gas and/or changing airflow direction.Such as, this director element 231 can in the recessed contracting of side wall 222 of this calyptra 22 to form this guiding groove 232 for changing the airflow direction of this admixture of gas to form a vortex-like mixture air-flow upwards respectively.Similarly, this director element 231 can one and inwardly extending from the inside wall of this mixed flow path 10 to form this guiding groove 232 in this mixed flow path 10, therefore, when combustion gas and air are by this guiding groove 232, change airflow direction supplies to light front fully air mixture and air to form vortex-like combustible gas stream by this guiding groove 232.

Need emphasis it is mentioned that this calyptra 22 and this one guiding groove 232 can together with by the mixed flow maximizing efficiency of air and combustion gas.This mixer element 21 is placed in this mixed flow path 10 will simplify installation and the structure thereof of this cyclonic arrangement 20, thus be minimized by the production cost of flow distributing and collecting device of the present invention, improve the complete burning degree of combustion gas simultaneously.Therefore, by this cyclonic arrangement 20, combustion gas and air can carry out premixed well, so that this combustion gas is burnt completely in this mixed flow path 10.

When air and combustion gas in this second hybrid chamber 102 through tentatively mixing after, flow to this cyclonic arrangement 20.When this preliminary mixed airflow comprising combustion gas and air runs into this cyclonic arrangement 20 years, 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 multiply mixed airflow by this group director element 231 of the change course device 23 of this cyclonic arrangement 20.This multiply mixed airflow enters each guiding groove 232 by this bottom notch of each guiding groove 232 of this change course device 23 of this cyclonic arrangement 20 respectively, and is drained to this first hybrid chamber 101 respectively by each guiding groove 232.And this second preliminary mixed airflow flows to this reservation cave 223, and in this reservation cave 223 further air mixture and air.Then this reservation cave 223 is flowed out by this group port of this side wall 222 in this reservation cave 223, flow into this guiding groove 232 that this group port 224 is corresponding respectively, again with tentatively mix the mixed airflow shunting out by first in this guiding groove 232 and mix again, combustion gas in this guiding groove 232 and air are mixed further in swirl shape mode, then flows into this first hybrid chamber 101.

The mixed airflow comprising air and combustion gas flowed out by this group guiding groove 232 strengthens mixed flow at this first hybrid chamber 101 in gyrate mode, more fully mixes with combustion gas to make air.In other words, the mixed airflow that this first hybrid chamber 101 provides space to make each shunting again mixed flow becomes a mixed airflow, thus improves the mixed flow efficiency of air and combustion gas.

Be worth emphasis it is mentioned that, when the pressure of this second hybrid chamber 102 of this mixed flow path 10 is enough large, combustion gas and air are sprayed to this cyclonic arrangement 20 after this second hybrid chamber 102 is tentatively mixed to form preliminary mixed airflow.This preliminary mixed airflow is shunted by this group guiding groove 232 of this change course device 23 of this cyclonic arrangement 20 and alters course, and shape, to the swirl shape air-flow risen, sprays to this first hybrid chamber 101 of this mixed flow path 10.This cyclonic arrangement 20 forms the swirl shape air-flow risen, and this swirl shape air-flow also reacts on this cyclonic arrangement 20, drives this cyclonic arrangement 20 to rotate.That is, this preliminary mixed airflow forms the swirl shape air-flow risen by this cyclonic arrangement 20, and this swirl shape air-flow mixes in the mode of vortex dress in this first hybrid chamber 101.At this group guiding groove 232 of this change course device 23 of this cyclonic arrangement 20 by the process of this preliminary mixed airflow shunting and changed course, after this preliminary mixed airflow is dividedly flowed into this group guiding groove 232, also produce a reaction force inside the continuous groove to this group guiding groove 232 to change the position of this guiding groove 232.Channeling direction due to this group guiding groove 232 is all consistent, is beneficial to form the gyrate ascending air risen, so that the direction of the reaction force producing inside the groove of this group guiding groove 232 is also consistent.And now this cyclonic arrangement 20 is also subject to the pressure effect that this preliminary mixed airflow sprays to this cyclonic arrangement 20.Be greater than the cross force produced inside the groove of this group guiding groove 232 with joint efforts this cyclonic arrangement 20 when being subject to the frictional force of the inboard wall of this gas channel 20, this cyclonic arrangement 20 starts to rotate.When this airflow apparatus 20 rotates, it is to the shunting of this preliminary mixed airflow, changed course, the efficiency forming the swirl shape air-flow risen improves greatly, and at this preliminary mixed airflow being also greatly improved by mixing efficiency during this cyclonic arrangement 20, thus also indirectly improve the mixing efficiency of the first hybrid chamber 101.

It is worth mentioning that, this cyclonic arrangement 20 multiple can be set in this mixed flow path 10 according to actual needs, this mixed flow path 10 is divided into multiple sub-hybrid chamber, and the mist comprising air and combustion gas through this mixed flow path 10 then can through shunting repeatedly, mixed flow thus obtain more abundant by this air and combustion gas mixing.

This flow distributing and collecting device comprises a part flow arrangement 30 further, and this part flow arrangement 30 suitably and be installed on this air stream outlet 11 place of this flow distributing and collecting device securely, for shunting this combustible gas comprising air and combustion gas sprayed from this air stream outlet.

As shown in Figure 4, this part flow arrangement 30 preferably has a head 31 and a lotus root meets portion 32 for securely this part flow arrangement 30 being installed on this air stream outlet 11, wherein this part flow arrangement 30 is by install or rotatably connected mode is installed on this upper outlet 12 securely, and such as this lotus root to connect on an external threaded portion in portion 22 and an inner peripheral wall of this mixed flow path 10 the threaded portion (figure does not draw) of correspondence.

Correspondingly, this head 31 of this part flow arrangement 30 defines a upper surface 311 and a lower surface 312, and wherein this head 31 is suitable for this air stream outlet 11 covering this mixed flow path 10.This part flow arrangement 30 has the one group of perforation openings 313 being preferably formed in this head 31 further, and extend to this surface 312 for being connected with this mixed flow path 10 from this upper surface 311, with mean allocation by this air stream outlet 11 through well-mixed combustible gas.Therefore, when this combustible gas by this air stream outlet 11 time, this combustible gas by this perforation openings 313 to spray this flow distributing and collecting device.In addition, each this perforation openings 313 preferably has taper first openend 3131 being 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.

Relative to this mixed flow path 10, first this perforation openings 313 is the passage of an elongation and the compartment of terrain that is preferably parallel to each other extends to this lower surface 312 from this upper surface 211 of this head 31, thus formed at this upper surface 311 place with one second openend 3132 relative be positioned at this lower surface 312, this first openend 3131 of wider opening.Therefore, this perforation openings 213 has from one of the extension of this wider taper first openend 3131 narrower passage 3133, to such an extent as to increases this ejection pressure through well-mixed combustible gas sprayed by this part flow arrangement 30 by this narrower passage 3133.

This head 31 place that this perforation openings 313 can be positioned at this part flow arrangement 30 fifty-fifty and radially for the air-flow on this upper surface 311 of mean allocation, wherein this head 31 further the center of this head 31 there is a core and around this in part one around part.The air-flow that this lower surface 312 being positioned at this core supplies to assemble and strengthen on this upper surface 211 of core to fovea superior contracting to form a center cavity 314 at this lower surface 312.

Be positioned at this first this second openend 3132 around this perforation openings 313 of part and can have a relatively wide opening in this lower surface 312 further.In other words, be positioned at this this second openend 3132 around this perforation openings 313 of part and preferably there is contrary taper, this contrary taper increases this perforation openings 313 diameter gradually downwards, and form relatively wide opening at this lower surface 312, therefore be positioned at this this perforation openings 313 around part the gaseous mixture scale of construction through this head 31 to be maximized, meanwhile, expulsion pressure can be improved when the combustible gas mixed passes the comparatively narrow passage 3133 of this perforation openings 213.

It is worth mentioning that, this upper surface 311 of this part flow arrangement 30 can burn thereon for flame.That is, flow distributing and collecting device of the present invention is suitable for collaborative arbitrary existence igniting set for lighting the combustible gas sprayed through this part flow arrangement 30 of flow distributing and collecting device of the present invention.Such as, this igniting set can be that a piezoelectric unit produces flame for lighting this combustible gas.Flame can burn on this upper surface 311 of this part flow arrangement 30.

The combustible gas comprising air and combustion gas in this first hybrid chamber 101 after abundant mixed flow, formation can supply clean-burning combustible gas, this combustible gas, when by this part flow arrangement 30, is first divided into two parts, one first combustible gas stream and one second combustible gas stream.This first combustible gas stream is assembled at this center cavity 314, these perforation openings 313 multiple of the core of this upper surface 311 of this part flow arrangement 30 again corresponding to this center cavity 214 shunt, and spray this part flow arrangement 30 from these perforation openings 313 multiple of the core of this upper surface 311.If this first combustible gas stream sprays from these perforation openings 313 multiple of the core of this part flow arrangement 30, and is lighted, then this first combustible gas be ejected is formed in the flame of centre of this part flow arrangement 30 burning.This second combustible gas stream is then split into multiply combustible gas stream by these perforation openings 313 multiple around this center cavity 314, be ejected into the non-central part of this upper surface 311 of this part flow arrangement 30 by each perforation openings 313 mean allocation, thus make this sprayed combustible gas can 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 enters this perforation openings 313 from this second openend 3132 of this perforation openings 313, then by this narrower passage 3133 of this perforation openings 313, then the upper surface 311 of this part flow arrangement 30 is ejected into from this first openend 3131 of this perforation openings 313.Because this perforation openings 313 has this narrower passage 3133, so that this expulsion pressure can be improved when this this narrower passage 3133 by this perforation openings 213 of combustible gas, thus improve the degree of heat of flame at this part flow arrangement 30 place.

Need it is especially mentioned that, this center cavity 314 can prevent flame when this upper surface 311 of this part flow arrangement 30 burns, and flame is extinguishing by turning greatly in little process.As shown in Figure 2, this the first combustible gas stream is compared with the two or two combustible gas stream, this the first combustible gas stream needs to shunt through this center cavity 314 these perforation openings 313 multiple just corresponding to this center cavity 314 of this part flow arrangement 30, pressurization ejection.This second combustible gas stream is then directly shunted by these perforation openings 313 multiple around this center cavity 314, pressurization ejection.That is, the flowing velocity of this second combustible gas stream is slightly faster than the flowing velocity of this first combustible gas stream.In other words, this center cavity 314 has served the slow of this first combustible gas stream, the effect of delay.When this part flow arrangement 30 upper surface burned flame from large to small time, particularly be transformed into and only have flame of centre when burning, combustion gas and air tentatively can mix with this second hybrid chamber 102 entering this mixed flow path 10 by this air intake 12 and this fuel gas inlet 13 lower than original speed, thus the speed causing the combustible gas of preliminary mixing to enter the first hybrid chamber 101 again by this cyclonic arrangement 20 also reduces.Originally then tentatively mix with original speed in the combustion gas of the first hybrid chamber 101 of this mixed flow path 10 and air, by this cyclonic arrangement 20, then enter this first hybrid chamber 101, then spray from this part flow arrangement 30.That is, former combustible gas sprays combustible gas that this part flow arrangement 30 slows down finally and flows out between this part flow arrangement 30 and there is a time difference.If at this moment in difference, do not have combustible gas to flow out from this part flow arrangement 30, then will extinguish at upper surface 311 burned flame of this part flow arrangement 30, thus cause gas leakage.And this center cavity 314 creates delay and slow effect to this first combustible gas stream, thus between causing at this moment in difference, also continue have combustible gas to flow out from this part flow arrangement 30, thus ensure that flame continues to burn at this upper surface 311 of this part flow arrangement 30, prevent flame from causing the situation of fray-out of flame to occur by turning greatly little.
