  • Publication number: 20080307967
    Abstract: An apparatus for reducing NOx comprising an exhaust conduit (101) of an IC engine (not shown) in which is placed a urea hydrolysis reactor (102) supplied with aqueous urea from urea storage tank (103). Flow of the hot exhaust gas through the exhaust conduit (101) heats the reactor (102) and causes the temperature of the urea therein to rise, promoting its hydrolysis and producing gaseous hydrolysis products. A pressure control valve (106) controls the release of the gaseous hydrolysis products from the reactor to a condenser (107). The condenser (107) is provided with a heat exchanger (108) which has an inlet (109) and an outlet (110) for connection to a coolant supply. When the gaseous hydrolysis gas enters the condenser (107) it is cooled by heat exchange with the engine cooling fluid and the ammonia and steam condense to form a pool of liquid in the bottom of the condenser (107).

  • Publication number: 20080210097
    Abstract: The present invention provides a deaerator and a deaerating method which enable the continuous deaeration of a liquid at a low cost. That is, with respect to a pipe which supplies a fluid by a supply means, a rip-out portion which rips out a fluid from an inner peripheral surface of the pipe is provided at a predetermined position in the inside of the pipe, and the fluid is supplied at a predetermined flow rate by a flow control means which adjusts the flow rate of the liquid which is supplied through the pipe so as to form a cavity on a downstream side of the rip-out portion. A through hole which communicates with the cavity is formed in the pipe, and deaeration of the liquid is performed by exhausting gases in the inside of the cavity by suction means such as a vacuum pump via the through hole.

  • Patent number: 7156895
    Abstract: A system for cleaning air wherein the air to be cleaned is bubbled up through an aqueous phase and an organic phase. The air is bubbled upwardly through the liquid to take advantage of the weight of the liquid to compress the gas, thereby increasing the solubility of the gas in the liquid. Because of specific gravity, the aqueous phase is generally at the bottom of at least one cylinder or container, and the organic phase is generally on top of the aqueous phase. Gases are removed either continuously or periodically to ensure that there are adequate reagents in the aqueous and organic phases, so that the reagents therein can be replaced as needed. There is no limit to the number of cylinders that can be used, depending upon the impurity and thus the amount of reagents to be used in treating the air.

  • Patent number: 6841138
    Abstract: A system for reducing the temperature of exhaust gas in an incinerator or boiler equipment having an exceedingly small size and avoiding any difficulties caused by damage to the wall surface of a gas cooling chamber due to adherence of sprayed water droplets and deposition of dust. More specifically, pressurized thermal water with a temperature higher than a boiling point of water under atmospheric pressure is sprayed as temperature reduction water into high temperature exhaust gas Gh in a gas cooling chamber or an exhaust gas duct. The temperature reduction of exhaust gas and the removal of acidic gas in the exhaust gas are simultaneously achieved by spraying pressurized thermal water Wt containing an alkaline solution as temperature reduction water into high temperature exhaust gas Gh in the gas cooling chamber or the exhaust gas duct.
