Description

A kind of air purification assembly adopting backward inclined centrifugal fan

technical field

The utility model relates to an air purification assembly adopting a backward inclined centrifugal fan, which belongs to the technical field of air purification equipment.

Background technique

Due to the severe outdoor haze intrusion into the room, interior decoration, building materials and electrical appliances, etc., the problem of indoor air quality has become increasingly prominent, which seriously threatens people's health. The emergence of air purifiers has become an effective method to solve indoor pollution.

At present, there are many types of air purifiers on the market. Ultimately, their purification performance against indoor pollutants mainly depends on the selection and combination of different air filters. The selection of existing air purifier filters is mainly based on its purification function for different indoor pollutants, such as purifying particulate pollutants, you can choose primary efficiency filters, medium efficiency filters, high efficiency filters, electrostatic filters, etc.; To purify gas pollutants, you can choose activated carbon filters, photocatalyst filters, low-temperature plasma filters, etc.; to purify biological pollutants, you can choose negative ion filters, ozone filters, etc. The purification effect will be unsatisfactory, and even secondary pollution will occur. For example, the purification components in some purifiers contain electrostatic filters, ozone filters, and ion filters, which will generate ozone and endanger human health; If there are too many filters, it will not only cause economic waste, but also increase the overall weight of the purifier. In addition, the selection of the fan also has an important impact on the purification effect of the purifier. If the air volume pressure head of the fan is too small, it cannot meet the requirements of the purification air volume and resistance, and the purification effect cannot be achieved; Loud noise, high energy consumption, no energy saving, etc.

Utility model content

The utility model discloses an air purification assembly adopting a backward inclined centrifugal fan. The air purification assembly formed by rationally arranging the sequence of different air filters effectively removes indoor particle pollutants and gas pollutants. The choice of fan not only meets the requirements of air volume and resistance for purification, but also has the advantages of compact structure, light weight, low noise, low energy consumption and convenient installation. While the ideal purification effect is achieved, the life of the fan is increased, which can effectively overcome the defects of the overall weight of the air purifier caused by the selection and combination of filters in the prior art, and secondary pollution, etc., and at the same time meet the requirements of low noise and low energy consumption. Require.

The technical scheme of the utility model is achieved in that:

An air purification component using a backward-inclined centrifugal fan, including: a nylon mesh primary filter, a gas-phase media filter, a high-efficiency filter, and a backward-curved centrifugal fan; the nylon mesh primary-effect filter is sequentially connected to the gas-phase medium from bottom to top Filter, high-efficiency filter, backward-curved centrifugal fan; the backward-curved centrifugal fan includes: an impeller and a motor, and the impeller is connected to the output shaft of the motor; the impeller includes an upper cover plate, a lower cover plate and blades; the blades are vertical It is arranged between the upper cover plate and the lower cover plate, and is in an arc shape; the lower cover plate is provided with an air suction port; and an air guide ring is arranged relative to the position of the air suction port.

There is an air filtration space between the backward-curved centrifugal fan and the high-efficiency filter, which is used to provide purification air volume and overcome purification resistance.

The function of the backward tilting centrifugal fan is to provide the purification air volume and overcome the purification resistance.

The air guide ring is arranged at the air suction port of the backward inclined centrifugal fan, which can not only make the air inhaled better, but also reduce the noise when the fan is running.

The air passes through the nylon mesh primary filter, gas phase media filter, high-efficiency filter, and finally enters the backward-curved centrifugal fan, and is sent out by the fan to protect the fan from particle and gaseous pollutants and increase the service life of the fan.

Advantages and positive effects:

The utility model adopts the air purification component of the backward inclined centrifugal fan, which has good removal effect on particle pollutants and gas pollutants. The proper air volume and pressure head of the backward-inclined centrifugal fan meet the requirements of air volume and resistance for purification; when the fan is running, the air first passes through the triple purification filter, and then passes through the backward-inclined centrifugal fan to purify the indoor air and protect the environment. The fan is free from pollution, which prolongs the life of the fan; at the same time, the utility model has the characteristics of compact structure, light weight, low noise, low energy consumption and convenient installation, etc., and provides a comfortable and quiet indoor environment for people.
