    摘要: An apparatus and method for abating ozone and reducing sulfuric acid from an exhaust stream. In a semiconductor manufacturing plant the processing of wafers involves the cleaning and etching of wafers, the resultant processing may produce gasses which must be abated. The apparatus and method utilizes UV light in high doses to convert ozone (O3) to oxygen (O2). By ensuring laminar flow through the UV light chambers, the efficiency of the system is sufficient to allow for the remaining impurities in the exhaust air to be removed through the use of an RTO.

    摘要: An air-purifying device for vehicles capable of diagnosing function deterioration of an ozone purifier with an inexpensive configuration is provided. At Step 120, applying current to an injector 20 is started. As a result, injection of ammonia from the injector 20 is started. Subsequently, it is determined whether or not i a heat generation amount is more than a predetermined amount A (Step 130). In the case of the heat generation amount>predetermined amount A, it can be determined that there are a large number of pores (fine pores) of activated carbon supporting a deterioration detection substance. In the case of the heat generation amount≦predetermined amount A, it can be determined that fine pores have decreased and an ozone purifying function of the activated carbon has deteriorated. Thus, an MIL 30 is lighted (Step 140).

    摘要: The present invention relates to an air purification device for vehicles and the purpose of the present invention is to provide a DOR (Direct Ozone Reduction) system which suppresses deterioration in purifying function of the ozone purifier. Ozone purification rate of activated carbon correlates with probability that gas is contacted with the radiator. Also, wind velocity of the gas passing through a radiator correlates with car speed. Therefore, the ozone purification rate of the activated carbon correlates with the car speed, The grill shutter 22 is controlled in fully open condition when the car speed is within an area faster than Speed A shown in FIG. 6. When the car speed is slower than Speed A, the grill shutter 22 is controlled in closed condition as shown in FIG. 2 (A).

    摘要: 1,182,734. Separating gas mixtures. BECKMAN INSTRUMENTS Inc. 14 June, 1968 [28 June, 1967], No. 28442/68. Heading B1L. [Also in Division C1 Ozone is removed from a gas stream containing sulphur dioxide and ozone by adsorbing the ozone with alkylthio mercury chloride, dialkylthio mercury alkylthio lead chloride, dialkylthio lead or a mixture thereof. The adsorbent is preferably coated on a granular support having a large surface area, and may be produced by reacting mercuric or lead chloride with a mercaptan, preferably ethyl mercaptan. Hydrogen sulphide and/or mercaptans may also be removed from the gas stream by adsorbing them with mercuric lead chloride, preferably coated on a granular support. The invention is applicable to removing impurities from a sulphur dioxide stream before it passes through an SO 2 analyser. The gas is passed through a scrubber 12 containing the adsorbents on the granular support (e.g. PTFE), which may be provided with a heater 20 to maintain the temperature at about 40‹C.
