Problems solved by technology

[0002] Gas purifiers in the prior art generally use filter cotton or activated carbon for multiple layers of filtration to adsorb particulate matter and harmful components in the gas. However, as the number of adsorbed particulate matter and impurities increases, the filter cotton or activated carbon The pores of the filter will be blocked, which will affect its filtration performance

Embodiment 2

[0030] On the basis of Embodiment 1, there are the following modifications in this embodiment:

[0031] Such as figure 2 , the filter cartridge 13 includes a plurality of cylinders with the same central axis and arranged alternately, only the outermost cylinder 131 and the top inner wall of the housing 10 are rotated and sealed by the sealing mechanism 15, and the walls of each cylinder The diameter of the micropores on the top gradually becomes smaller in the direction of gas travel; a coiled high-pressure water spray pipe 9 is provided in the gap between adjacent cylinders, which is used to spray water on the inner wall of the corresponding cylinder; The bottom end is closed, and the top of the adjacent cylinder is sealed and connected; only the top port of the innermost cylinder 132 communicates with the exhaust port on the top wall of the housing 10; the coiled high-pressure water spray pipe 9 is connected to all The water inlet of the hollow shaft 12 is connected.

Embodiment 3

[0033] A working method of the gas purifier described in the above embodiment 1 or 2, comprising: the gas to be purified is input into the housing 10 from the air inlet, enters the filter cartridge radially from the outside of the filter cartridge 13 under the action of air pressure, Part of the particles or oil in the gas is adhered to the outer wall of the filter cartridge 13, and the water spray hole on the hollow shaft sprays water to the inner wall of the filter cartridge at regular intervals or all the time;

[0034] At the same time, the hollow shaft drives the filter cartridge to rotate, so that the water in the filter cartridge passes through the micropores on the wall of the filter cartridge under centrifugal force, reaches the outer wall of the filter cartridge, and scours the outer wall of the filter cartridge particulate matter on.

[0035] The water in the upper box at the bottom of the housing 10 is sent to the shower 7 in the housing 10 through the water pump 5...

Embodiment 4

[0040] On the basis of the above-mentioned embodiment 1 or 2 or 3, the working method of the gas purifier specifically includes: the gas input into the casing 10 from the air inlet passes through the gas equalizing plate 6, and goes upward evenly; Part of the particulate matter is mixed with the mist generated by the filter screen 11, and falls to the water storage tank 1 at the bottom of the housing 10 under gravity; another part of the particulate matter in the gas is filtered upward through the primary filter material layer 14, and the gas continues upward. Under the action, it enters the filter cartridge radially from the outside of the filter cartridge 13, and the remaining particles or oil in the gas are adhered to the outer wall of the filter cartridge 13; the water spray hole on the hollow shaft 12 sprays water to the inner wall of the filter cartridge ;

[0041] At the same time, the hollow shaft drives the filter cartridge to rotate, so that the water in the filter c...

Abstract

The invention relates to an air purifier which comprises a shell, wherein a hollow shaft is in running fit with the interior of the shell; a filtering drum which is used for filtering air fixedly sleeves the hollow shaft; the bottom of the filtering drum is closed while the top is open; a plurality of water spraying holes are distributed in the filtering drum and on the peripheral walls of the hollow shaft; the top end of the hollow shaft is used for connecting a high-pressure water source so that the water spraying holes can spray high-pressure water to the inner wall of the filtering drum; the hollow shaft is in running fit with a driving mechanism so that the filtering drum is rotated; the opening part at the top of the filtering drum and the inner wall of the shell are in running sealing fit with each other through a sealing mechanism; an air inlet which is used for inputting to-be-purified air is formed on the wall of the shell and located under the sealing mechanism; an air outlet which is communicated with the opening part of the filtering drum is formed on the wall of the shell.

Description

technical field [0001] The invention relates to a gas purifier, which filters the gas containing impurities such as particles. Background technique [0002] Gas purifiers in the prior art generally use filter cotton or activated carbon for multiple layers of filtration to adsorb particulate matter and harmful components in the gas. However, as the number of adsorbed particulate matter and impurities increases, the filter cotton or activated carbon The pores of the filter will be blocked, which will affect its filtration performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas purifier and its working method, which can prevent the filter cartridge from being blocked by particles or impurities while purifying the air. [0004] In order to solve the above-mentioned technical problems, the present invention provides a gas purifier, which includes: a closed casing, a hollow shaft arranged longitudinally is ...
