Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat-exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.

A dust collecting module of a desulfurizing apparatus for removing sulfur oxides is easily installed and facilitates the application of a high voltage to discharge electrodes. The dust collecting module includes an arrangement of discharge electrodes and dust collecting electrodes alternately disposed and spaced apart from each other, the discharge electrodes configured to be charged to a predetermined voltage for generating a corona discharge between the discharge electrodes and the dust collecting electrodes; a first setting beam having a plurality of lower slots into which the discharge electrodes are securely inserted; and a lower frame extending in a stacking direction of the discharge electrodes to support the discharge electrodes, wherein the predetermined voltage is applied to the discharge electrodes through the lower frame and the first setting beam. The dust collecting module may further include an insulating connecting member from which the lower frame is suspended.

An exhaust treatment system includes a dust-removal system. The dust-removal system has an electric field device (1021) and an exhaust cooling device. The electric field device (1021) includes an inlet of the electric field device, an outlet of the electric field device, a dust-removal electric field cathode (10212), and a dust-removal electric field anode (10211), the dust-removal electric field cathode (10212) and the dust-removal electric field anode (10211) being used for generating an ionization dust-removal electric field. The exhaust cooling device is used for reducing an exhaust temperature before the inlet of the electric field device. An exhaust dust-removal system facilitates to reduce greenhouse gas emission, and also facilitates to reduce hazardous gas and pollutant emission, so that gas emission is more environment-friendly.

A thermal power plant exhaust purification device, the device including a cooling substance flow channel and an exhaust flow channel; the device also includes a spacing member for spacing and exchanging heat between the cooling substance flow channel and the exhaust flow channel, the spacing member having an exhaust contact surface for collecting dust and/or mist contained in the exhaust; the cooling substance flows in the cooling substance flow channel, such that the condensate precipitated from hot exhaust uniformly adheres on the exhaust contact surface, thus forming a uniform and stable water film; on one hand, formation of the concentrated H.sub.2SO.sub.4 on a dust collecting plate is prevented, and a liquid film flows downwards under gravity, thereby cleaning the H.sub.2SO.sub.4 adhered on the dust collecting plate timely; on the other hand, the water film is very effective in intercepting droplets and capturing the dust.

A system and method for removing contaminants from emissions including the use of a matrix for selecting application specific copper, zinc, tin, sulfide (CZTS) sorbent compounds. The CZTS sorbent compound is a reactive material that removes contaminates from gaseous and/or non-gaseous emissions. The CZTS sorbent compound becomes a broad-spectrum reactive material with enhanced properties when alloyed specifically with precise elements targeting specified contaminates present in application specific emissions. The matrix disclosed herein defines which enhancement element is best suited for application specific compounding. The method may include testing the contaminated emissions and then routing the emissions through one or more specific filters based on pairing contaminates with filters containing corresponding CZTS sorbent compounds.
