In one embodiment, a carbon dioxide capturing system includes an absorber configured to include a first contact portion that brings a combustion exhaust gas containing carbon dioxide into contact with an absorbing liquid containing an amine compound, cause the absorbing liquid to absorb at least a portion of the carbon dioxide in the combustion exhaust gas at the first contact portion, and release the combustion exhaust gas. The system further includes a washing apparatus configured to include a second contact portion that brings the combustion exhaust gas released from the first contact portion of the absorber into contact with a washing liquid, and configured such that the combustion exhaust gas and the washing liquid are individually fed to an upstream side of the second contact portion.

An air scrubber has an electrically driven fan and a drum having a mat forming a closed circulating band spanning a support of the drum. The mat is electrically rotatably driven about a rotation axis, wherein a lower part of the drum is immersed in a water basin. The mat can be removed from the drum by a movement in the axial direction and pushed back on again by a movement in the axial direction.

The present invention relates to an electric grill comprising a purification and circulation system for removing oil mist and smoke and, more particularly, to an electric grill comprising a purification and circulation system for removing oil mist and smoke, wherein: a suction hole and a discharge hole are installed around a grill plate; air containing oil mist, smoke, heat, and smell is suctioned through the suction hole, the suctioned air containing, oil mist, smoke, heat, and smell is introduced into the lower portion of the grill by a suction fan, and comes into contact with water on the upper side of an oil pan containing the water, so as to remove the oil mist, smoke, heat, and smell contained therein, and then the purified air is circulated through the discharge hole installed around the grill plate; a filter is disposed so as to completely remove the oil mist, smoke, heat, and smell; and a Coanda air guide is installed so as to facilitate the contact between the oil mist, smoke, heat, and smell and the water, whereby the oil mist, smoke, heat, and smell can be completely removed.

A complex malodor removing equipment includes: a neutralizing module which dissolves a portion of malodor-causing substances, in malodorous gas introduced from malodor-producing equipment, in liquid water and removes same, which includes an acidity neutralizing module that introduces an alkaline substance from outside and removes an acidic malodor-causing substance from the malodor-causing substances, and an alkaline neutralizing module that introduces an acidic substance from outside and removes an alkaline malodor-causing substance from the malodor-causing substances, and which connects the acidity neutralizing module and the alkaline neutralizing module; and a balancing module which dissolves the remainder of the malodor-causing substances, in the malodorous gas introduced from the neutralizing module, in water and removes same, which includes an oxidation balancing module that introduces an oxidizing agent from outside and balances the malodor-causing substances, and a reduction balancing module that introduces a reducing agent from outside and balances the malodor-causing substances.

According to one embodiment, a dust collection apparatus includes a liquid supplier, a first member, and a liquid recoverer. One end of the first member is connected to the liquid supplier, one other end of the first member is connected to the liquid recoverer. The first member is conductive. The first member has a first surface including a plurality of trenches.

Provided is a wet cyclone apparatus including a body, an inlet installed in the body, and having a passage through which air including airborne particles is sucked in, a wet cyclone connected to the inlet to wet and collect the airborne particles introduced from the inlet, and a water storage installed in the body to store water, wherein the wet cyclone includes an air suction port into which the air introduced from the inlet is sucked, a water inlet through which water is supplied from the water storage, and a sample outlet through which the collected wetted sample is extracted and discharged.

A wet abatement system which can suppress the accumulation of foreign matters in a treatment gas line is proposed. There is provided a wet abatement system for detoxifying treatment gas by bringing the treatment gas into contact with liquid. The wet abatement system includes an inlet casing having an inlet port from which the treatment gas is let in and an outlet port provided below the inlet port and through which the treatment gas flows, and a liquid film forming device provided between the inlet port and the outlet port and configured to form a liquid film on an inner wall surface of the inlet casing. A heater configured to heat the inlet casing is embedded in an interior of a wall portion of the inlet casing, the wall portion constituting a portion situated above the liquid film forming device.

A gas inlet system for a wet gas scrubber includes a weir configured to deliver liquid to a scrubbing passage to wet the interior surface of the scrubbing vessel during operation of the gas inlet system. The weir include a weir duct and a weir trough extending at least partially around the weir duct to receive and at least partially fill with liquid during operation of the gas inlet system. The weir trough has an upper trough outlet in liquid communication with the upper weir duct inlet to deliver liquid from the weir trough into the upper weir duct inlet during operation of the gas inlet system. The weir trough also has a lower trough outlet below the upper trough outlet. The lower trough outlet is in liquid communication with the scrubbing passage to deliver liquid from the weir trough toward the scrubbing passage during operation of the gas inlet system.
