An exhaust gas purification device includes an exhaust gas discharge unit having an exhaust gas passage, and a plurality of smoke purifying units. Each smoke purifying unit includes a smoke purifying module disposed outside of the exhaust gas discharge unit and including an elongated smoke purifying holder defining a channel, and at least one water spray pipe for spraying water into the channel. An exhaust gas capture module includes a first exhaust gas capture pipe communicating the exhaust gas passage with the channel and having a first smoke trap extending into the exhaust gas passage.

According to one embodiment, a fan scrubber includes an inlet pipe to be connected to a post-stage side of a vacuum pump, in a state where a film preparation apparatus is arranged at a pre-stage before the vacuum pump, a process chamber connected to the inlet pipe, and containing a fan connected to a main shaft of a motor, a heater configured to heat the inlet pipe, and a controller configured to control turning on/off of the heater. The controller turns off the heater, when a signal received from the film preparation apparatus has been switched from a film preparation signal to a cleaning signal.

An oily smoke purification device includes a holder, a main housing, a mixing mechanism, a filter and an exhaust fan. The holder is filled with purification solution, the exhaust fan is started to cause a negative pressure inside the main housing, oily smoke enters the purification solution from a gap between the holder and the main housing and is mixed with the purification solution under an action of the mixing mechanism to absorb dirt in the oily smoke into the purification solution, and the oily smoke is filtered by the filter to generate clean air which is sucked by the exhaust fan. The hazardous substance including oil, dust and other impurities in the contaminated air is filtered and the air is purified, thereby protecting the environments and ensuring the heath of people.

A method of treating the atmosphere of a storage of vegetable products with a volume greater than 200 m.sup.3, wherein the method comprises at least one step of contacting the atmosphere with a liquid flow by circulation in a packing. A treatment unit of the atmosphere of a storage of vegetable products having a volume greater than 200 m.sup.3, wherein the unit comprises a contacting device comprising a packing, a device for injecting a liquid flow into the contacting device, a device for circulating the storage atmosphere in the contacting device, wherein the contacting device is so designed that the atmosphere is brought into contact with the liquid flow by circulation in the packing.

There is provided an active coke regeneration mixed vapor treatment method. The method comprises the following process steps of: A) performing a first water condensation on a mixed vapor produced during an active coke regeneration process by spray water in a first condensation zone; B) performing a second water condensation on the mixed vapor that is after the first water condensation by spray water in a second condensation zone, to further condensate and purify the mixed vapor; C) eliminating moisture in a gas through mist elimination from the gas fraction in the mixed vapor that is after the second water condensation, and discharging the remaining gas from the upper of the second condensation zone; and, D) discharging active coke micro powder in the mixed vapor that is after the second water condensation, with condensation water. In the present invention, an apparatus for implementing the abovementioned method is also provided.

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

An exhaust configuration for a wet scrubber. The exhaust configuration includes a diffuser that is attached to the wet scrubber and which defining an outlet for discharging scrubbed air and paint laden water from the wet scrubber. Attached on lateral sides of the diffuser are wings. The wings extend away from the outlet.

An air washer includes an outer case having an air suction port, a water tub disposed in the outer case to store water, a humidification unit disposed in the water tub, a display unit disposed so as to be spaced apart from the outer case to form an air discharge port, the display unit having a water supply port, through which water is supplied, an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air suction port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub, and a blower disposed in the inner case to blow air suctioned through the air suction port to the air discharge port.

Disclosed is a wet air purifier that eliminates contaminants while contaminated air passes therethrough by causing the contaminated air to come into contact with water. The wet air purifier suctions external air by rotating a rotary fan installed therein and disperses water droplets by causing water to collide with a rotary fan to increase a contact surface between air and water. In the wet air purifier, a mixture of the contaminated external air and the water is made to pass through a long narrow passage and guided to a storage tank in which contaminants are settled. In this way, the wet air purifier increases a retention time and a collision time of water and contaminated air. The wet air purifier also can function as a humidifier.

A wet scrubber apparatus has a housing with access doors and guides that allow for the installation of self-contained baffle modules. Selected baffle modules can to be inserted, exchanged, removed or left blank (no baffles) within the wet scrubber housing, depending on the desired process. The wet scrubber allows for variable performance and feature-enhancing for a target efficiency and effectiveness. The wet scrubber can incorporate a pump and pipe manifold fluidizer design that can spray water or fluid up onto the modules during operation of the wet scrubber to keep collected material off the baffles. Water can be sprayed throughout the modules onto the baffles during operation, or when the scrubber is offline, isolated from the gas to be scrubbed, during a cleaning operation. This water or fluid can come from an outside source or can be piped and valved to recirculate existing scrub water or fluid.
