Problems solved by technology

These methods of removing oily fume and peculiar smell generally have the problem of poor effect. Among them, the adsorption and deodorization of activated carbon is easy to be saturated, and bacteria and mold may also multiply and stink on the activated carbon, thereby causing secondary pollution; The health of the photocatalyst is harmful; the photocatalyst needs to increase the ultraviolet lamp, which consumes more power, and the ultraviolet light will accelerate the aging of the plastic. ), platinum (Pt), silver (Ag) and other precious metals generally have ...

Embodiment 1

[0044] Such as figure 1 , 2 As shown, a composite oil fume purifier with a coupling function includes a housing 1, the left and right ends of the housing 1 are respectively provided with an air inlet 11 and an air outlet 12, and between the air inlet 11 and the air outlet 12 A gas channel is formed between them, wherein the air inlet 11 and the air outlet 12 are respectively provided with an air inlet hood 111 and an air outlet hood 121, which are used to guide the incoming and outgoing gas, and the cross sections of the air inlet 11 and the air outlet 12 are circular The cross-section of the airflow channel expands into a square shape. At the same time, along the air inlet 11 to the air outlet 12, a fume separation unit 2, an electrostatic collection unit 3, and a catalytic absorption unit 4 are sequentially arranged in the gas passage. The fume gas flows from the air inlet 11 through the The diversion function of the air inlet cover 111 passes through the oil fume separatio...

Embodiment 2

[0065] First 5.1g Al 2 o 3 Mix with 500ml deionized water, emulsify for 5 minutes to form a suspension with a concentration of 0.1mol / L, dip the honeycomb ceramic carrier plate into the above suspension, and dry it in an oven at 100°C.

[0066] Next, to 500ml concentration is 0.1mol / L Fe (NO 3 ) 3 5 g of water glass was added to the solution, and emulsified for 5 minutes to obtain a catalyst active component precursor.

[0067] Finally, immerse the treated honeycomb ceramic plate in the precursor solution, put it in an oven and dry it, then place it in a muffle furnace and heat it at 200°C for 2 hours to obtain the required catalyst. Fe in the prepared catalyst is calculated 2 o 3 with Al 2 o 3 The mass ratio is 12%.

[0068] The FeOx honeycomb ceramic supported catalyst prepared above was placed in the catalytic absorption unit 4, and the oil fume purifier was turned on. It was measured that the grease in the oil fume was removed at one time by 91.8%, the removal effic...

Embodiment 3

[0070] First 20.4g Al 2 o 3 Mix with 500ml of deionized water, emulsify for 5 minutes to form a suspension with a concentration of 0.4mol / L, soak the honeycomb ceramic carrier plate in the above suspension, and put it in an oven for drying at 100°C.

[0071] Next, to 500ml concentration is 0.14mol / L Co (NO3 ) 2 7.5 g of bentonite was added to the solution and emulsified for 5 minutes to obtain a catalyst active component precursor.

[0072] Finally, immerse the treated honeycomb ceramic plate in the precursor solution, put it in an oven and dry it, then place it in a muffle furnace and heat it at 300°C for 3 hours to obtain the required catalyst. The calculated amount of CoO and Al 2 o 3 The mass ratio is 2%.

[0073] The CoOx honeycomb ceramic supported catalyst prepared above was placed in the catalytic absorption unit 4, and the oil fume purifier was turned on. It was measured that the grease in the oil fume was removed at one time by 94.2%, the removal efficiency of p...

Abstract

The invention provides a compound type cooking fume purifier with a coupling function. The compound type cooking fume purifier comprises a shell, wherein the shell is provided with an air inlet and an air outlet; a gas channel is formed between the air inlet and the air outlet; the gas channel is internally provided with a static electricity capturing unit and a catalytic absorption unit in sequence from the air inlet to the air outlet; the static electricity capturing unit comprises an ionization region and a capturing region; the catalytic absorption unit comprises a catalyst and a carrier for loading the catalyst; the catalyst comprises an active component and an auxiliary component; the active component is an oxide of a transition metal element; the auxiliary component is Al2O3 or TiO2. The cooking fume purifier is simple in structure, low in manufacturing cost, high in purification efficiency, compact in structure and long in service life and does not need to be frequently maintained; the catalytic absorption unit can be used for purifying upper-state cooking fume molecules stimulated by the static electricity capturing unit under a room temperature.

Description

technical field [0001] The invention relates to the field of oil fume purifiers, in particular to a composite type oil fume purifier with a coupling function. Background technique [0002] With the progress of society, people's awareness of environmental protection and health is increasing, and the impact of pollution generated in the kitchen cooking process on the environment and health has attracted more and more attention. Kitchen cooking pollution mainly comes from gas combustion emissions and cooking fumes, in which the main pollutants emitted by gas combustion are CO, NOx, SO 2 and particulate matter, etc., while cooking fumes include edible oil and food volatiles at high temperatures and their condensate aerosols, water vapor, and a mixture of indoor dusty gases. The components contained are quite complex, including saturated fatty acids and unsaturated fatty acids. , plus a variety of short-chain aldehydes, ketones, acids, alcohols and other irritating taste product...
