[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment kitchen fume recovering and purifying system.
Fig. 2 is the structure chart of the utility model embodiment rotary sieve degreasing unit.
Fig. 3 is the theory diagram of the utility model embodiment kitchen fume recovering and purifying system control circuit.
[specific embodiment]
The structure of the utility model embodiment kitchen fume recovering and purifying system as shown in Figure 1 to Figure 3, comprise mechanical oil removal equipment, blower fan 6 and control circuit and three grades of degreasing units, the first order is mechanical oil removal equipment, and the second level is ultraviolet photolysis device, and the third level is catalytic decomposition of ozone device 9.
Wherein, mechanical oil removal equipment is rotary sieve degreasing unit 4, and the air inlet pipe of rotary sieve degreasing unit 4 connects exhaust fume collecting hood 1, and the blast pipe of rotary sieve degreasing unit 4 connects ultraviolet photolysis device.
Ultraviolet photolysis device is electrodeless ultraviolet light solution device 5, comprises housing and ultra violet light emitter, and ultra violet light emitter is arranged in the housing of electrodeless ultraviolet light solution device, and ultra violet light emitter adopts electrodeless ultraviolet lamp.
Blower fan 6 is arranged between the housing and photolysis case 8 of electrodeless ultraviolet light solution device 5, and muffler 7 is arranged between blower fan 6 and photolysis case 8.
Catalytic decomposition of ozone device 9 is arranged on the rear portion of photolysis case 8.The exhaust duct 10 of the outlet welding system of catalytic decomposition of ozone device 9.
Fire resisting damper 2 is arranged in the blast pipe of rotary sieve degreasing unit 4.Temperature sensor 12 and aerosol fire-extinguishing device 3 are arranged on before fire resisting damper 2, between rotary sieve degreasing unit 4 and fire resisting damper 2.
Fire resisting damper 2 is electrically-controlled valve, and temperature sensor 12, aerosol fire-extinguishing device 3, fire resisting damper 2A, fire resisting damper 2B, rotary sieve degreasing unit 4, electrodeless ultraviolet light solution device 5 and blower fan 6 be the controller 11 of connection control circuit respectively.
When the temperature of temperature sensor 12 perception reaches setting value, controller cuts out rotary sieve degreasing unit 4, blower fan 6, ultraviolet photolysis device 5, fire resisting damper 2, starts aerosol fire-extinguishing device 3, and the flame in the blast pipe of rotary sieve degreasing unit 4 is put out.
The structure of rotary sieve degreasing unit 4 as shown in Figure 2,
In rotary sieve degreasing unit 4, because oil is rotated to form filter screen by the electric fan with filtering function and catches, the effect that is then centrifuged power is got rid of to surrounding and is directly entered oil guide groove 13, then flows to oil storage bottle 14, above the blade of electric fan, substantially do not have oil and adhere to, therefore stable.
Aerosol fire-extinguishing device is the fire extinguishing that is applicable to small-sized confined space, and the fire of oil smoke class is mostly to catch fire in smoke pipe, before smoke pipe burns, can not have influence on the external world, and after therefore catching fire, by smoke pipe sealing, extinguishing device can extinguish the blaze rapidly after starting.
Electrodeless ultraviolet light solution device is because life-span of electrodeless ultraviolet lamp pipe super general ultraviolet fluorescent tube far away, and production cost is lower than common fluorescent tube, and power of lamp tube is also much higher than common fluorescent tube, so use cost is much lower, also high to flue gas decomposition efficiency.
The utility model is implemented in the following way, after kitchen fume produces, from exhaust fume collecting hood 1, be inhaled into, through rotary sieve degreasing unit 4, remove smoke particle, remainder enters electrodeless ultraviolet light solution device 5, through microwave, ultraviolet, ozone, after the multiple reaction mechanism such as hydroxyl radical free radical is decomposed, be centrifuged blower fan 6 strong pumping, through muffler 7, reduce noise, then enter photolysis case 8 and continue reaction, photolysis case 8 is hollow box bodies, because ozone oxidation decomposing organic gas need to have certain reaction time, therefore at photolysis case 8, fully after reaction, through catalytic decomposition of ozone device 9, decompose remaining ozone gas again, through exhaust duct 10, enter in the air.
The waste oil of 4 pairs of collections of rotary sieve degreasing unit regularly reclaims.Air outlet at rotary sieve degreasing unit 4 is provided with fire extinguisher 3, fire resisting damper 2 and temperature detect switch (TDS) (temperature sensor) 12, just in case breaking out of fire, when temperature surpasses the setting value of temperature detect switch (TDS) 12, close synchronously fire resisting damper 2, rotary sieve degreasing unit 4, centrifugal blower 6 and electrodeless ultraviolet light solution device 5, open fire extinguisher 3, blocking-up air communication channel, and fire is extinguished.
Kitchen fume recovering and purifying system of the present utility model, the first order adopts the oil removing of rotary sieve degreasing unit, and the oil of removing regularly reclaims in oil storage bottle, because direct centrifugal throwing away after the oil in cooking fume is caught by filter screen, on blade, can not adhere to, therefore, operation also can be stablized; The second level adopts electrodeless ultraviolet light solution device, and lamp tube service life is longer, and use cost is lower, and treatment effect is better; The third level adopts catalytic decomposition of ozone device, because photodissociation process has ozone generating, if do not processed, can become again new pollution sources, by after catalytic decomposition of ozone just can low-altitude discharged.
