The present invention relates to an air purification device. The housing includes a main passage section through which air is introduced from a room through a main inlet port and is discharged to an outside through a main outlet port, and a bypass passage section partitioned from the main passage section, through which air is introduced from the room through a bypass inlet port and is discharged to an outside through a bypass outlet port. The main inlet port damper opens and closes the main inlet port. The main outlet port damper opens and closes the main outlet port. The bypass damper opens and closes the bypass passage section. The controller is configured to control the bypass damper so as to open the bypass passage section when the main passage section is closed due to a malfunction of the main inlet port damper or the main outlet port damper.

Air purification device

An air cleaning device is disclosed. A first opening and closing member opens and closes an inlet of a housing. A second opening and closing member opens and closes an outlet of the housing. A first filter unit collects and separates foreign substances from contaminated air in the housing. A circulation tube has a first end portion disposed at the inlet to communicate with the housing and a second end portion disposed at the outlet to communicate with the housing. A third opening and closing member opens and closes the circulation tube. A first heater is installed inside the circulation tube to heat air in the circulation tube. A blower is installed inside the circulation tube to deliver air from the circulation tube into the housing.

Air cleaning device

An apparatus for collecting soluble component-removed powder that collects soluble component-removed and poorly soluble component-containing powder to recycle by removing the soluble component from the powder through filtering using a vacuum pump after mixing soluble component-removed and poorly soluble component-containing powder and a solvent dissolving the soluble component, and a method of the same.

Gathering method and apparatus of powder separated soluble component

A ceramic filter and method for preparing the same. The method for preparing the ceramic filter according to the present invention is characterized in comprising the steps of: (a) coating firstly a ceramic green paper prepared by using a slurry solution comprising ceramic fiber of 0.1-10 mm length, with an aluminum silicate solution and drying the firstly coated paper; (b) coating secondly the dried ceramic green paper with an aluminum phosphate solution and drying the secondly coated paper; and (c) calcining the dried ceramic green paper obtained from the step (b). The ceramic filter according to the present invention has excellent mechanical strength since the bonding strength between ceramic fibers is very high, and shows good porosity, gas permeability, and efficiency for capturing microparticles since the pores between the ceramic fibers are less blocked, and thus can be very usefully applied to gas exhaustion system for automobile.
