Specific implementation mode:
Below in conjunction with the accompanying drawings, invention is further described in detail.
With reference to figure 1, the present invention is a kind of kitchen flue gas waste heat recycling system, including two parts, and first part is temperature Poor electricity generation module, the part include the thermoelectric generation film 3 for interspersing among pipeline wall surface and the accumulator 4 for storing electricity;Second part For heat pipe heat exchanging module, which includes the insulating layer 5 being wrapped in outside pipeline, and 6 one end of gravity heat pipe heat exchanger is embedded in pipeline In, the other end connects water tank 7, and water tank 7 carries integrated automatic control device 8.System is that collection smoke box 1 and oil smoke are net from band part Change device 2.Wherein, oil stain is removed by collection smoke box 1 and oil cleaner 2, then by thermoelectric generation film 3, using the air-cooled side pair in side Stream heat exchange form generate electricity, and connect accumulator 4 carry out electricity storage, be envisaged for kitchen illumination, ultraviolet lamp sterilization with It is fresh-keeping etc. with food materials.Flue gas after cooling enters back into outdoor utilidor and carries out 6 recycling of gravity assisted heat pipe waste heat, and gravity assisted heat pipe changes Hot device 6 and water tank 7 can ensure heat exchange efficiency in upper form.Water tank 7 is automatically controlled in conjunction with integrated automatic control device 8 to heat The domestic water that can obtain constant temperature eventually passes through the low-temperature flue gas after two-stage heat exchange and is discharged from smoke outlet.It is integrated to automatically control Device 8 includes water valve 801, liquid level alarm 802, liquid level shelves 803, thermocouple 804, diode converter 805 and control electromagnetism Valve 806.Integrated automatic control device 8 can control the water in water tank 7 according to smoke, make water supply constant water temperature, specific to control Process is, after 804 temperature-sensitive of thermocouple, connects control solenoid valve 806 by diode converter 805, realizes the real-time of water valve 801 The cycle of control;Liquid level shelves 803 are connected with liquid level alarm 802, for more than preset water level alarm.
Temperature-difference power generation module uses small-sized thermoelectric generation film 3, is embedded in latticed pipeline, and cold side uses wind It is cold, reduce water cooling equipment, simplify system structure, reduces system energy consumption.
Temperature-difference power generation module uses semiconductor temperature differential generating technology, and operation principle is in two pieces of semiconductors of different nature As soon as a temperature difference is arranged in both ends, then DC voltage is produced at semiconductor both ends.Semiconductor thermoelectric power generation has the noiseless, longevity The features such as life is long, performance is stablized.The present invention uses small-sized thermoelectric generation film, by oil fume purifier 2 to heat pipe heat exchanging module This section of tubing is made latticed, and according to being inlaid into thermoelectric generation film between grid, which need not do Insulation, temperature difference hair High-temperature flue gas was washed away in electric piece side, and air-cooled, the formation power generation temperature difference is taken in side.
It is furnished with ancillary equipment in the part:Accumulator 4 and inverter 9.Accumulator 4 is by being converted to of electric energy of thermoelectric generation film Can store, and recharged by reversible chemical reaction realization and used for electrical appliance;Inverter 9 --- DC communication is converted Device is made of inverter bridge, control logic and filter circuit, (generally by the converting direct-current power into alternating-current power in accumulator 220V, 50Hz sine wave), it is used for electrical appliance.
Heat pipe heat exchange water tank workflow is discussed in detail with reference to figure 2.
Heat pipe heat exchanging operating water tank workflow is divided into heat pipes heat process and temperature controlled processes.In heat pipes heat mistake When journey works, the closed working medium of 6 inner vacuum of gravity heat pipe heat exchanger being made of heat pipe holds evaporation to absorb in heat source (flue gas) Heat, condenses in cold end (water tank 7) and releases heat, and the water in heat transfer feed-tank 7 completes the heat pipes heat course of work.
When temperature controlled processes work, the thermocouple 804 in embedded water tank 7 perceives the variation of water temperature.To ensure water temperature dimension Hold it is constant, when 6 heat transfer intensity of gravity heat pipe heat exchanger reduces, 804 sense temperature of thermocouple decline, pass through diode converter 805 control solenoid valves 806 stop adding water or reduce amount of water to corresponding liquid level shelves 803.When gravity heat pipe heat exchanger 6 exchanges heat When intensity increases, then 804 sense temperature of thermocouple rises, and controls solenoid valve 806 by diode converter 805, increases and add water It measures to corresponding liquid level shelves 803.Wherein, Liquid level process is as follows:Liquid level shelves 803 are worked together with thermocouple 804, work as water temperature When excessively high, solenoid valve is opened, and liquid level increases to n+1 gears by n gears.If water temperature is higher than system design pressure T at this time, control Solenoid valve is opened, and water filling is continued, and liquid level rises to n+2 grades by n+1 grades.Repeat above-mentioned work.Until water temperature is less than design temperature T then controls solenoid valve closing, stops water filling.
In addition, in order to ensure the safety of system work process, liquid level alarm 802 is added, when liquid level is less than liquid level When lower limiting value, system design pressure is reduced, is controlled by electromagnetic conversion and increases water injection rate, prevent dry combustion method.When liquid level is higher than upper liquid level When warning value, system design pressure is improved, is controlled by electromagnetic conversion and stops water filling, while reminded user in time with water and preventing from noting Hypervolia damages system.
