摘要:
A method for producing a damper for an air line of an internal combustion engine includes the following steps: providing a temperature-controlled inner part having passages; producing a tubular preform of an outer jacket from a thermoplastic melt; and attaching the temperature-controlled inner part to a blowing mandrel of a blow mold, which is open. The blowing mandrel has outlet openings and the passages are positioned over the outlet openings. The method further includes bringing the temperature-controlled preform over the inner part and closing the blow mold such that the preform is blown against the walls of the blow mold, whereby an outer jacket is obtained. Simultaneously, local connections between the inner part and the outer jacket are obtained by pressing the preform and the inner part against each other in some regions. Finally, the blow mold is opened and the damper is removed.
摘要:
An apparatus for treating a contaminated fluid has a UV lamp within a tubular housing. A plurality of baffles within the housing create meandering pathways parallel to the lamp for exposing the fluid to the UV light along the entire length of the pathways. A photocatalytic coating on the baffles and inner surfaces of the housing is maintained within a pre-set radial distance, preferably no more than about 75 mm, from the lamp for optimal creation of a photocatalytic reactant. The contaminated fluid flowing through the meandering pathways is maintained in close proximity to the lamp and has adequate time for exposure to the ultraviolet light and photocatalytic reactant for treatment before exiting the housing. The baffles are removably positioned within the housing for convenient maintenance or to alter the length of the pathways, without re-sizing the housing. This apparatus is considered an affordable and compact environmental protection device capable of “redefining pollution control” by potentially mitigating close to 100% of harmful bacteria and toxic compounds.

摘要:
A condensing assembly for urging condensation of a vapour into a liquid has a vertically stacked modular array of horizontal condensation units exposed to a heat transfer medium. Each condensation unit has a cooling chamber, a plurality of hollow legs and necks accessing the cooling chamber to define a fluid passageway. An open or enclosed space between vertically opposed condensation units is created by coupling the necks and legs of opposed condensation units. Introduced vapour travels along the fluid passageways and through the cooling chambers for condensation into liquid, which then travels along the fluid passageways to a storage tank. A cooling loop in each cooling chamber increases condensation. Vapour funnels in the condensation units along the fluid passageway reduce vapour to liquid contact therealong. An inlet header provides additional cooling to the vapour prior to entering the condensation units.

An assembly for condensing a vapour and storing the resulting condensed liquid has a condensation unit for condensing the vapour which is located above a dual containment storage tank for storing the resulting condensed liquid.

A containment assembly for storing a liquid substance above a ground support surface has an inner tank for receiving and storing the liquid and an outer tank surrounding the inner tank and forming a first air space therebetween for trapping any of the liquid which might escape said inner tank. A support beneath the outer tank provides a second air space between the outer tank and the ground support surface, and a thermal insulating layer substantially envelopes the inner tank, outer tank and support from the ambient. A vapour exhaust vent is provided atop the inner tank, which may include a liquid scrubber for recovering liquids from discharging gases and returning the liquids to the inner tank or elsewhere. Piping is provided for liquid communication between the inner tank and external liquid sources for filling and emptying the inner tank. Instrumentation for measuring the amount of liquid in the inner tank includes a shut-off mechanism for stopping the flow of liquid through the piping to the inner tank when the liquid reaches a pre-set level in the tank. A detector accesses the first air space for detecting liquid leakage from the inner tank. Air exchange is promoted between the first and second air spaces by a plurality of open ended standpipes spaced about the first air space and in air communication with the second air space. A heater is preferably provided for forcing heat into the second air space, the heat being distributed through an the standpipes into the first air space and about the inner tank. A second inner tank may be located beneath the outer tank for liquid storage, and may be partitioned for handling selected liquids.
