摘要:
An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.

[Object] To provide a gas decomposition apparatus and a gas decomposition method in which no safety problems occur in spite of the application of a relatively high voltage between an anode and a cathode for the purpose of decomposing odorous gases of many types.[Solution] A catalytic electrode layer 6 that contains a catalyst and is porous; a counter electrode layer 7 that forms a pair with the catalytic electrode; and an electrolyte layer 15 that is sandwiched between the catalytic electrode and the counter electrode and has ion conductivity are included. The catalyst is held by the catalytic electrode in the form of being carried by a carrier containing a conductive material or the catalyst is directly carried by the catalytic electrode. A conductive material in the catalytic electrode, the conductive material being in contact with the catalyst, is not a noncovalent carbon material.

Disclosed is a mat or molded pre-form that may be used as a mounting mat to mount a fragile monolith within an outer housing of an exhaust gas treatment device, such as automotive catalytic converters and diesel particulate traps. The mat or pre-form may also be used as thermal insulation in the end cone regions of the exhaust gas treatment device. The mat and pre-form includes an inorganic microporous insulation component and a flexible fibrous material component. Exhaust gas treatment devices and methods for making exhaust gas treatment devices including the mat or pre-form are also disclosed.

A ventilation member (100) of the invention includes a tubular part (11), a gas permeable filter (19), and a cover part (31). In an attached state where the tubular part (11) is fit into the cover part (31), gaps functioning as gas passages (AR2 and AR3) are formed between a bottom portion (35) of the cover part (31) and the gas permeable filter (19) and between a side wall portion (39) of the cover part (31) and a body portion (17) of the tubular part (11). The opening area (S2) of a filter-end opening (15) with respect to an in-plane direction (WL) perpendicular to the thickness direction of the gas permeable filter (19) is larger than the opening area (S1) of a connection-end opening (13) with respect to the in-plane direction (WL).
摘要:
The catalyst module is designed for use in an emission control system of a stationary incinerator. It comprises a stack frame, into which several mounting units are inserted strung together. The mounting units have a peripheral side wall as well as several partitions, which are entangled with one another and form a lattice with a plurality of mounting shafts, in which in each case one catalyst is inserted. The catalysts are pressed into position preferably with the interposition of an elastic fitting element.

The device comprises a support (20) and at least one basket (22A to 22E) carried by said support (20). The basket (22A to 22E) comprises an upstream apertured wall (60) and a downstream apertured wall (62) together defining an intermediate space (70) for receiving the solid product (24). The upstream apertured wall (60) defines, opposite the intermediate space (70), a feed passage (90) for the upstream flow, and the downstream apertured wall (62) defines, opposite the intermediate space (70), a discharge passage (92) for a treated flow. The upstream apertured wall (60) and the downstream apertured wall (62) are mounted in such a way that said apertured walls can be moved freely in relation to one another and in relation to the support (20), on a given expansion path.

Provided is a catalyst structure which prevents an increase in pressure loss by a simple construction while the gas flow is efficiently stirred by a structure making contact between adjacent catalyst elements. The catalyst structure is provided with a first flat-plate part and a second flat-plate part which support, on surfaces thereof, a constituent having catalytic activity to an exhaust gas and face each other, and a stirring part which is provided in such a manner as to come into contact first with the first flat-plate part and the second flat-plate part in an extending manner from the first flat-plate part to the second flat-plate part at a prescribed angle with respect to the direction in which the exhaust gas flows.
