Detailed description of the invention

Below in conjunction with Figure of description and embodiment, the present invention is further described.

As shown in Figure 1, these flue gas waste heat recovery kitchen range, comprise the burner hearth 2 being arranged in the kitchen range top 1, the burner 3 that is positioned at the chamber of a kitchen range 2 and heat-exchange device 4.Heat-exchange device 4 carries out heat exchange for high-temperature flue gas and air that burner hearth is discharged, is therefore provided with smoke air inlet 41 and corresponding flue gas gas outlet 44, and heat exchange medium---the air inlet 43 of air and corresponding air gas outlet 42.

Burner hearth 2 tops are provided with high-temperature flue gas and collect mouth 211, and the corresponding burner hearth cavity of this collection mouth is high-temperature flue gas collecting chamber 21, and therefore high-temperature flue gas collecting chamber 21 is the ring-type around inboard wall of burner hearth.The bottom of burner hearth 2 is provided with double-deck hearth wall, forms heating cavity 22 between double-deck hearth wall, and heating cavity 22 is the internal communication with burner 3 by hot oxygenation pipeline 23.High-temperature flue gas collecting chamber 21 is connected with smoke air inlet 41 by the collecting chamber 21 on it and high-temperature flue gas pipeline 24, and smoke air inlet 41 is communicated with flue gas gas outlet 44 by heat exchange bend pipe 45 in heat-exchange device 4.

In order to increase heat exchanger effectiveness, the present embodiment is also provided with air blast 6 and air exhauster 5 is set.Flue gas gas outlet 44 at above-mentioned heat exchanger is connected with air exhauster 5 by high-temperature flue gas pipeline 24 in heat-exchange device 4 outsides, like this, under the effect of air exhauster 5, the high-temperature flue gas that the interior combustion reaction of burner hearth 2 produces can be efficiently collected into heat-exchange device 4 fast.Air inlet 43 outsides at above-mentioned heat exchanger are connected with air blast 6 by cold-air duct 64, air inlet 43 and air gas outlet 42 are in heat-exchange device 4 internal communication, air gas outlet 42 is communicated with heating cavity 22 by high temperature oxygenation pipeline 25, thereby make the passage by above-mentioned connection containing oxygen air through heat preheating at delivery date, air blast 6 is blown into extraneous air in heat-exchange device 4, extraneous air and high-temperature flue gas carry out heat exchange and form high temperature containing oxygen air in heat-exchange device 4, high temperature enters heating cavity 22 containing oxygen air by high temperature oxygenation pipeline 25, the part heat that combustion reaction produces conducts in heating cavity 22 via inboard wall of burner hearth, high temperature is formed hot containing oxygen air containing oxygen air in heating cavity by post bake, generally can reach 200 ° of C, the hot oxygen air that contains is delivered to burner inside by hot oxygenation pipeline 23, be supplied to the fuel-bound in burner, there is more fierce combustion reaction fully in the hot oxygen air that contains that temperature is higher, both improved flame temperature, make again the utilization ratio of fuel greatly improve.

For comparatively large-scale kitchen range, because the exhaust gas volumn producing is larger, in order to give enough spatial cache of high-temperature flue gas, the collecting chamber 22 of upper furnace can be set to the toroidal cavity of chamber of a kitchen range sidewall lateral direction depression, as Fig. 2.And small-sized kitchen range arrange high-temperature flue gas collection mouthful in upper furnace and just can.In addition, heat-exchange device is intended to the exchange heat in high-temperature flue gas to the air entering wherein, and the present embodiment has adopted comparatively common heat-exchanger rig, also can use other heat-exchange devices, can realize equally above-mentioned hot-swap feature, and therefore not to repeat here.

Further, the present embodiment is provided with high temperature containing oxygen air intake 221 and hot containing oxygen air outlet slit 222 at heating cavity 22 outer walls, high temperature is communicated with air gas outlet 42 by high temperature oxygenation pipeline 25 containing oxygen air intake 221, and the hot oxygen air outlet slit 222 that contains is by the internal communication of hot oxygenation pipeline 23 and burner 3, in heating cavity 22, be provided with at high temperature containing oxygen air intake and hot containing the interlayer 26 between oxygen air outlet slit.Interlayer 26 is the ring seal interlayer arranging around burner 3, this interlayer is provided with some through holes 261, making to heat cavity is positioned at the inside and outside part of interlayer and interconnects, thereby increase high temperature and contained the stroke of oxygen air in heating cavity, after having avoided high temperature to enter heating cavity containing oxygen air, directly alter to hot oxygenation pipeline, promoted corresponding heating effect.Similarly, interlayer can be also the arc not sealing, and due to lattice gear effect and the prolongation better effects if to corresponding air flow stroke of the annular interlayer sealing, the present embodiment has adopted above-mentioned annular interlayer.The present embodiment is considered for technological angle in addition, thereby the double-deck hearth wall that lower furnace portion is set to be easy to realize has formed corresponding heating cavity, the structure of heating cavity is not limited to this, simply, as shown in Figure 3, the partition 210 of multiple arcs is set from top to bottom in heating cavity, one side of each partition 210 is to be connected side with hearth outer wall, opposite side is unsettled unsettled side, connection side and the unsettled side of adjacent partition are crisscross arranged, make the Layered-space that between each layer of partition, formation interconnects, the middle part of partition arranges the circular hole adapting with burner external diameter, burner outer wall is frustum conventionally, the part that partition contacts with burner can comparatively closely coordinate, high temperature enters each Layered-space through progressively entering burner 3 inside from hot oxygenation pipeline 25 after heating containing oxygen air from high temperature oxygenation pipeline 24.

As previously mentioned, high-temperature flue gas is under the effect of air exhauster 5, to enter heat-exchange device 4, and in order to solve the emission problem of heat exchange low temperature waste gas later, the present embodiment is connected by pipeline air exhauster air outlet with emission-control equipment 7.Emission-control equipment is for being equipped with the container of liquid for treating waste gas (as foaming akaline liquid), and container is provided with inlet 71 and liquid outlet 72.

Described in above-mentioned each section, the present invention in use, the waste gas that burning produces enters heat-exchange device from high-temperature flue gas collecting chamber by high-temp waste gas pipeline, the air blowing in heat-exchange device with air blast carries out heat exchange generation high temperature containing oxygen air, high temperature enters containing oxygen air the heating cavity that is positioned at hearth wall via pipeline, it is hot containing oxygen air containing the rear formation of oxygen air secondary heating to high temperature that inboard wall of burner hearth conducts the heat, hotly enter in burner combustion reaction is carried out to oxygenation containing oxygen air, improve efficiency of combustion, saved raw material.The high-temperature flue gas of discharging from heat-exchange device becomes the waste gas of low temperature after heat-exchange device cooling, and it is fully inhaled molten processing after entering emission-control equipment, has stopped the pollution of the flue gas in cooking process to atmospheric environment.
