Description
Technical field
The present invention relates to oil smoke processing and heat recovery fields, and in particular to kitchen fume processing and waste heat recovery one
Body makeup is set.
Background technology
The energy and sustainable development are current era major issues of interest, and it is current society to improve energy utilization rate
The most important thing that can develop；Meanwhile with economic development and improvement of living standards, problem of environmental pollution also becomes one
Hot issue, more and more people appreciate pollution problem of the kitchen flue gas to air.
The kitchens such as commercial kitchen, especially dining room, school lunch service, it is larger, it can be produced in the process of food
Raw a large amount of high-temperature oil smokes.Contain a large amount of particulate matters and pollutant in these high-temperature oil smokes, outdoor is discharged into smoke exhaust ventilator, it is right
Ambient air causes pollution, while a large amount of waste heats contained in oil smoke are wasted, and exacerbate the raising of periphery outdoor temperature.It is right
High-temperature oil smoke, which is handled and carries out waste heat recovery, can effectively improve energy utilization rate, reduce the pollution to surrounding enviroment.
In order to be purified to kitchen fume, Chinese invention patent " cooking fume cleaner " (application number：
201610995489.X date of publication：2017.01.11 oil smoke) is passed through clean room, clean room is divided into several by oil smoke refinement web plate
A purifying area, oil smoke are sprayed onto by the clear water with pressure when refinement web plate on web plate, and water mist repeatedly mixes repeatedly with oil smoke,
Temperature decline is condensed into liquid and floats on the surface, and greasy dirt is discharged by oil extraction funnel.A kind of Chinese utility model patent " kitchen
Fume purifier of fume " (application number：201620593499.6 the day for announcing：2016.12.21) with wind turbine exhaust gas is attracted to petticoat pipe
Interior and introduce exhaust gas into purifier by defeated smoke pipe, the filtrate in purifier decomposes oil smoke, and gas is by going out after decomposition
Smoke pipeline discharges, and oil stain is discharged after being collected by absorption oiled-plate method by oil outlet.A kind of Chinese utility model patent " kitchen oil fume purifying
Device " (application number：201720143176.1 the day for announcing：2017.12.22 oil smoke when clarifier in pipeline by that can have in)
Effect removes part oil and harmful substance, and in addition precipitators can effectively blow butterfly after entering pipeline, and baffle is made to rotate, and keep off
Through-hole on plate can effectively filter oil and harmful substance in cooking fume, and greasy dirt cleanser can be immersed in when baffle rotates to lower end
In, oil and other substances on gauze can be effectively removed by greasy dirt cleanser.
In order to realize oil smoke waste heat recovery, a kind of Chinese invention patent " kitchen residual heat retracting device " (application number：
201710594216.9 date of publication：2017.11.10 motor drives flabellum rotation by oil smoke inspiration smoke pipeline in), oil smoke
In heat by the cool water heating in smoke pipeline inner cold water pipe, can by tap in hot water after heating injection water tank
Release hot water.A kind of Chinese utility model patent " waste-heat recovery device for kitchen use " (application number：201520793252.4 bulletin
Day：2016.03.02 it) is fully absorbed by the way that screw type heat exchanger tube is arranged on the outer wall of smoke exhaust ventilator air intake passage and is discharged
Waste heat in oil smoke and steam prepares hot water for kitchen use with this heat.Chinese invention patent " a kind of kitchen oil fume purifying and waste heat
Recycle integrated apparatus " (application number：201610927831.2 date of publication：2017.01.11 inertial separation method, quiet) is utilized
Electric high-pressure dust-cleaning method, absorption method and ultraviolet catalytic method carry out reasonable combination and are purified to oil smoke, are returned with air source heat pump
The waste heat that oil smoke and cooking stove generate is received, is used for kitchen in the heat transfer to water of recycling, hot water is collected simultaneously by phase transformation water tank
Waste heat is stored in phase-change material.
As the above analysis, existing patented technology spininess is independent to kitchen oil fume purifying or waste heat recovery problem at present
It is introduced, and for the only a small amount of research of the combination of both technologies.Waste heat recovery patented technology mostly uses heat exchanger and oil
The mode recovery waste heat of cigarette heat exchange, present in main problem be that oil smoke is without purification, easily in heat exchanger after exothermic condensation
Wall surface forms grease, and heat exchange efficiency is caused to decline.Although patent " integrally disguise by a kind of kitchen oil fume purifying and heat recovery
Set " fully consider the combination problem of fume purifying and waste heat recovery, but its fume purifying segment structure is complicated, and clean-up effect is poor,
It purifies of high cost.
Invention content
The present invention is in order to solve the fume purifying section knot of existing kitchen oil fume purifying and heat recovery integrated apparatus
Structure is complicated, the clean-up effect difference problem of high cost with purification, and proposes that a kind of kitchen fume is handled and waste heat recovery is integrally disguised
It sets.
A kind of processing of kitchen fume and waste heat recovery integrated apparatus include air-supply passage, heat-exchanging water tank, air exhaust passage, wind
Machine, heat exchange coil, filter and air-valve；
