PROBLEM TO BE SOLVED: To improve the elimination efficiency of nitrogen oxide in an exhaust emission control device for purifying exhaust gas containing nitrogen oxide. SOLUTION: The exhaust gas g of a device generating exhaust gas (for example, a diesel engine 1) flows into an inner tube 14 through an discharge route 2, and is diffused by an impingement plate 16. The diffused exhaust gas g is discharged from an outlet 13b after particulate matter is oxidized and eliminated by an oxidation catalyst 15a, the particulate matter is captured by a metal filter 15b, and nitrogen oxide (NOx) is converted by a NOx filter 15c. In this exhaust emission control device, catalyst activation material 15f is carried by the NOx filter 15c. The catalyst activation material 15f includes a spinel compound metal oxide comprising manganese, cobalt and copper, and is composed of nano particles of particle diameter not greater than 100 nm.

PROBLEM TO BE SOLVED: To improve reliability by suppressing vibration due to air flow of a heat generation plate, for example, while uniformizing temperature distribution. SOLUTION: A tension spring 53 is energized to pull a holding body attaching plate 64 upward, a movable holding body 61 is pulled upward, and a bent part 37 of a metallic heater 28 is pulled toward the outside of the metallic heater 28. When the metallic heater 28 is extended by thermal expansion in heating, the bent part 37 together with the movable holding body 61 moves outward along the length direction of respective heat generation regions 36b of the metallic heater 28, thereby preventing curving (deflection) of the metallic heater 28, and preventing vibration of the metallic heater 28 due to the flow of air.

PROBLEM TO BE SOLVED: To provide a double chamber type waste gas treatment apparatus which can prevent occurrence of thermorunaway at the time of regeneration treatment of an adsorbent and shorten the regeneration time of the adsorbent. SOLUTION: When abnormal temperature increase occurs at the time of regeneration treatment, thermorunaway at the time of the regeneration is prevented by conducting some of operations such as nitrogen gas injection to a regeneration duct 29 from a nitrogen gas lead-in pipe 52, cease of circulation of a component gas by stopping a blower 33 for regeneration and at the same time closing a flow rate control damper 53, and shutdown of a power source of a heating part 31 in combination. Further, the time of regeneration of the adsorbent is shortened by efficiently carrying out cooling/heating of the component gas flowing in the regeneration duct 29 by installing a heat releasing bypass pipe 56 bypassing the regeneration duct 29 of the regeneration part 11 and equipped with a heat releasing fin 54a and a bypass damper 55. Furthermore, cooling/heating of the component gas is efficiently carried out by surrounding the heat releasing fin 54a with a heat insulator and blowing cold air/hot air to the heat releasing fin 54a.

PROBLEM TO BE SOLVED: To enable a cleaning without damaging in a state that a dust collecting unit is installed to improve the usability. SOLUTION: An electric dust collector 10 collects floating fine particles contained in air suctioned from an suction port 102a by the dust collecting unit 11. The dust collecting unit is constituted by a corona discharge part charging the floating fine particles in air by generating the corona discharge and an electrical collecting part allowing the floating fine particles charged by a discharge electrode to adhere electrically to a collection electrode plate 25. The collection electrode plate is installed so as to be vertical, an inflow opening 11a of air is positioned above the collection electrode plate, and also an outlet 11b of air is positioned in the lower part. The collector includes a dust removing unit 51 peeling the attaching floating fine particles from the collection electrode plate of the dust collection unit to omit, and a recovering box 131 recovering the omitted floating fine particles positioning below the outlet of the dust collection unit.

PROBLEM TO BE SOLVED: To perform decomposition safely and surely at low cost, for example, when VOCs desorbed from an adsorbent are catalytically decomposed. SOLUTION: The main control unit of a monitor control system 13 actuates an air injection pump 34 when the temperature detected by a temperature detection part 38 reaches the injection initiation temperature during the regeneration in the first adsorptive removal part 8 (or the second adsorptive removal part 9) and controls the air injection pump 34 based on the treatment gas flow detected by a treatment gas flow detection part 36 and the injected air flow detected by an injected air flow detector 37 so that the injected air flow/treatment gas flow ratio falls at a specified value. Here, the injection initiation temperature is set according to the temperature at which the desorption of VOCs begins. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To suppress reduction of a temperature of a metal plate and to enhance a removal efficiency of a black smoke particulate. SOLUTION: In the subject metal filter 1, when a diesel exhaust gas is passed through an inter-layer gaps 14 of the metal filter 1, a projection with a surface 11 functions as an obstacle of a flow F, an unburned black smoke particulate floating in the exhaust gas is easily captured on front and back surfaces of the metal filter 1 near the projection with a surface 11 and a through hole 12. The unburned black smoke particulate captured by the metal filter 1 is heated and burned by the metal filter 1 of a high temperature and a surrounding atmosphere. A large number of ceramic particles 15 having relatively large heat capacity are filled in the inter-layer gaps 14 of a metal porous body 13 of corrugated roll-like shape, thereby the metal porous body 13 is maintained to a high temperature. Thus, the unburned black smoke particulate is heated and burned to be removed from the metal filter 1. As a result, the flow F of the exhaust gas passed through the metal filter 1 is discharged as a clean gas containing no black smoke particulate. COPYRIGHT: (C)2006,JPO&NCIPI

摘要:
PROBLEM TO BE SOLVED: To enable exact determining of a VOC (Volatile Organic Compounds) removal state. SOLUTION: A main control part acquires data on VOC concentrations of the inlet/outlet sides of a VOC treatment part 8 from a VOC sensor unit, and the ratio of the difference between the VOC concentrations to the VOC concentration of the inlet side, is calculated as a rate of VOC removal, which is in turn, shown in a digital display. In addition, the main control part decides whether or not the initiation of a regeneration treatment is required, based on a preset reference rate of VOC removal. Then as such a requirement is decided, an indicator lamp of a regeneration warning display/regeneration execution button, is turned on. COPYRIGHT: (C)2009,JPO&INPIT
