摘要:
A photocatalyst cellular component (100) and a photocatalytic purification apparatus (10), increasing to the greatest extent a contact area between polluted air and a photocatalyst, ensuring to the greatest extent that a sufficient amount of ultraviolet rays is shone onto the surface of the photocatalyst, and, at the same time, allowing the flow resistance applied to air flowing in a flow channel to also satisfy the field of ventilation systems having increased requirements on flow resistance. The photocatalyst cellular component (100) is constituted by one or more photocatalyst cellular filter cores (110) and a photocatalyst cellular component housing (120). The photocatalyst cellular component filter cores (110) employ a cellular arrangement. The photocatalyst cellular filter cores (110) are constituted by three or more filter core basic units (111') and a light guide component (115') that is Y-shaped when viewed from an end. In the three filter core basic units (111') adjacently paired with each other, a first filter core basic unit (111'a) and a second filter core basic unit (111'b) are provided with a shared first light guide plate (111'ab1), the first filter core basic unit (111'a) and a third filter core basic unit (111'c) are provided with a shared second light guide plate (111'ac1), the second filter core basic unit (111'b) and the third filter core basic unit (111'c) are provided with a shared third light guide plate (111'bc1), and the first to third light guide plates (111'ab1, 111'ac1, and 111'bc1) constitute the light guide component (115').

The present invention provides a novel method for treating soil-contaminated water, the method using a photocatalytic material capable of efficiently removing, by light irradiation alone, volatile organic compounds and heavy metals that give rise to soil contamination. The present invention provides a method for treating soil-contaminated water that detoxifies volatile organic compounds contained in soil-contaminated water using a photocatalytic material, the method being characterized by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a gas phase, and (2) decomposing the volatile organic compounds contained in the gas phase obtained in step (1) using the photocatalytic material. The present invention further provides a method for treating soil-contaminated water using a photocatalytic material to remove heavy metals contained in the soil-contaminated water, the method being characterized by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a liquid phase, and (2) removing the heavy metals contained in the liquid phase obtained in step (1) using the photocatalytic material.
摘要:
The invention relates to a method for producing activated carbon provided and/or impregnated with a metal-organic framework substance (MOF material), the activated carbon being in particular in the form of discrete activated carbon particles, and preferably for producing an activated carbon with a reactive and/or catalytic action. The metal-organic framework substance is produced in situ in the pores and/or in the pore system of the activated carbon, starting from at least one metal precursor compound (MP) containing a metal and at least one ligand precursor (LP).
摘要:
Device for air filtration and purification comprising an enclosure for the flow of the air, said enclosure comprising an air inlet opening and an air outlet opening; one or more inner plates arranged inside said enclosure at an inclined angle in respect of the air flow direction, between said air inlet and outlet, and arranged such that the air flows along such inclined inner plate or plates; one or more UV light emitters arranged inside said enclosure to emit UV light over said inner plates and over said air flow; wherein said inner plates are photo-catalytic and are electrostatic precipitators. An embodiment comprises one or more pairs of said inner plates, wherein each pair of inner plates is placed side-by-side transversally to the airflow and in a cross-shape arrangement with the two plates being arranged inclined at 45° from the bottom surface of the enclosure.
摘要:
To provide a device and a method for oxidation decomposition treatment of a hazardous gas of a volatile organic compound (VOC) or the like at normal temperature. A gas treatment device characterized in being provided with a plasma-generating unit and a catalyst medium. The plasma-generating unit is provided with at least a flow channel through which a gas to be treated flows; and a power-supply unit for supplying electrical power, a first electrode, a second electrode and a dielectric material arranged inside the flow channel. A voltage is impressed between the first electrode and the second electrode by the power-supply unit and electrical discharging is caused to occur, whereby plasma is generated. The catalyst medium is adapted for accelerating a reaction with the gas to be treated and is provided in a position where the plasma generated by the plasma-generating unit inside the flow channel is present, wherein the catalyst medium has metallic catalytic particles present on an inorganic substance.
