Composite air purification device

Abstract

The invention provides a combined type air cleaning unit. The combined type air cleaning unit comprises a shell, wherein a filter screen for dividing the shell into an upper cavity and a lower cavity is arranged in the middle of the shell, the lower cavity is taken as a water filter cavity, the upper cavity is taken as a buffer cavity, two air inlets for introducing air into the lower cavity along tangential direction of the inner wall of the shell are formed in the lower cavity, the air inlet directions of the two air inlets are opposite, an air outlet is formed in the upper cavity, a water outlet is formed in the lower cavity, and a water inlet is formed in the upper cavity. The combined type air cleaning unit has the advantages that water rotates under driving of power of air, air bubbles passing through the filter screen are deformed, so that air and water fully contact. Through the reasonable arrangement of the air inlets, air is tangentially injected through an air pump to generate rotating water, the air pump drives the water to rotate while injecting air. The combined type air cleaning unit has the advantages that the structure is simplified, the cost is lowered, the maintenance is convenient, energy is saved, and the filtering effect is good.

Description

technical field [0001] The invention relates to an air purification device, specifically an air purification device mainly using water as a filter medium. Background technique [0002] In order to maintain the indoor air quality, many indoor spaces are equipped with ventilation devices or air purification devices. For example, ventilation devices installed in radio recording studios. These devices generally drive the air flow through the fan, send the outdoor air into the room after filtering, or carry out the circulation filtering process of the indoor air. Filtration devices are an important part of these devices and are the key to determining indoor air quality. Currently the most used on these devices are as figure 1 The main components of the shown cloth mesh filter include a buffer box, and a cloth mesh is arranged at the outlet of the buffer box. The inlet of the buffer box is connected with the air compressor or the fan, the air is introduced into the buffer box ...
