Problems solved by technology

High-voltage discharge is required to generate negative charges, which increases the manufacturing cost of the device and may generate ozone at the same time. An activated carbon filter must be installed to remove ozone
Photocatalytic oxidation using ultraviolet lamps and high-temperature chemical catalytic oxidation also have similar problems. They need to use ultraviolet lamps or air heaters, and also need to use catalysts. The manufacturing cost is high, and ozone may also be generated at the same time. Activated carbon filters must be used to prevent to clear

Embodiment 1

[0041] Combine below figure 1 The basic working procedure of the embodiment of the present invention is further described. The polluted air enters from the air inlet 1, and then enters the water inlet chamber 2. In the water inlet chamber 2, there is a circulating washing liquid nozzle 13, and the washing liquid pumped in from the liquid storage tank 11 is evenly distributed to the Venturi throat through the nozzle 13. On mouth 3, air and washing liquid enter Venturi throat 3 together, and the speed of air in Venturi throat 3 reaches more than 30 m / s, affected by the boundary of Venturi throat 3, the air in Venturi throat 3 A high velocity gradient is formed in the airflow, which generates extremely high shear force, and disperses the washing liquid entering the throat into uniform and fine water droplets. The damper 4 arranged at the outlet of the Venturi throat or inside is used to adjust the size of the air passage of the Venturi throat 3. After leaving the Venturi throat ...

Embodiment 2

[0044] In embodiment two, the main body of the device is basically the same as embodiment one, the difference is that the gas-liquid separation adopts the cyclone separator 15 to carry out gas-water separation, and the droplets of the cyclone separator 15 entering the gas-liquid separation chamber 6 are subject to centrifugal force It acts as a centrifugal motion, and finally collides with the inner wall of the cyclone separator to leave the air. The dehydrated clean air passes through the fan 8 and enters the air outlet 9, and then enters the room again.

[0045] The purification effect on indoor air is shown in Table 1 and Table 2. The concentrations of PM2.5 particles and large particles in the indoor air before entering the device are 327 and 9 μg / m3 respectively 3 . SO 2 The concentration is 200μg / m 3 , the formaldehyde concentration is 300μg / m 3 .

Embodiment 3

[0051] In embodiment three, the main body of the device is basically the same as embodiment one, the difference is that gas-liquid separation adopts chemical adsorption layer 16 to carry out gas-water separation, and the gas-liquid mixture entering the gas-liquid separation chamber 6 enters in the chemical adsorption layer 16, moisture It is adsorbed on the surface of the chemical desiccant and leaves the air, and the dehydrated clean air passes through the fan 8 and enters the air outlet 9, and then enters the room again.

Abstract

The invention provides a novel indoor air purification device. Water or an aqueous solution is used for absorbing various types of gas and granular pollution components in air, so that the aim of purifying the air is fulfilled; a Venturi throat opening is formed in an air channel; when the gas passes through the throat opening, the speed of gas flow is obviously increased, and high shearing force is formed in the gas flow, so that liquid entering the Venturi throat opening is sheared into extremely thin fog drops; after leaving the Venturi throat opening, the gas flow is slowed down and forms strong turbulent fluctuation, so that particles in the air and the extremely thin water drops can be in full contact and collision, and the particles in the air are transferred into liquid; the water drops in a turbulent fluctuation region also collide, and the water drops are re-enlarged, so that the water drops can be removed from a gas-liquid separation chamber, and the gas pollution components in the air are dissolved in the liquid so as to be absorbed and removed.

Description

technical field [0001] The application of the present invention relates to a new type of indoor air purification device, which mainly uses the Venturi effect and the principle of washing liquid absorption to clean and purify indoor air, and has the characteristics of small size, high efficiency, cleanliness and energy saving. Background technique [0002] Indoor air pollution comes from both indoor and outdoor causes. Indoor causes include volatile organic compounds including formaldehyde and xylene released from wall paints, furniture paints, carpet or wood adhesives, various cleaning agents, etc. Soon after people live in a new house, they are prone to sick building syndrome (sick building syndrome), which is caused by poor ventilation in the new house and the air is filled with more of these gases; in addition, various odors released during the cooking process in the kitchen, toilet Various odors (including H 2 S, dithiol, indole and other organic or inorganic gases), t...
