IPC: B01J19/00
Filed: 1994-03-11
Abstract: ABSTRACT OF THE DISCLOSURE     The object of the present invention is an acoustic chamber for the treatment, at various frequencies, of gas effluents which contain solid and liquid microparticles in suspension.  The acoustic energy agglomerates the microparticles, thereby facilitating the air separation by means of conventional systems (electro-filters, cyclones, etc.).  The chamber has a rectangular cross section and is axially traversed by the flow of aerosols to be agglomerated while the acoustic generators which are the stepped vibrating plate type and which may have different frequencies, are contiguously or alternatingly arranged on the side walls in order to create intensive stationary fields in the various cross sections of the chamber.  In order to maximize the emission of both faces of the radiant plate of the acoustic generators, it is proposed to arrange the plate between two forming angle planar reflectors.  Additionally, for the treatment of aerosols at high temperatures, there is provided a refrigeration system in order to refrigerate the acoustic radiators by means of a cool air flow.

Patent CA-2152360-A1 (CA)
Inventor: FISCHER JOHN C
IPC: B01J20/28
Filed: 1994-01-06
Abstract: Desiccant-coated substrates, regeneratable rotary dehumidification wheels and other devices for gas (e.g., air) treatment using those substrates, and processes for making them are disclosed. The substrates may have coatings in thicknesses of from about 2 to about 10 thousandths of an inch (about .051 to .254 mm) containing particles of one or more adsorbent desiccants and an organic water-based binder. The desiccant particles retain a high fraction of their original absorption capacity because the pores of the desiccant particles contain a pore-clearing agent prior to the binder setting and the pore-clearing agent leaves the pores during the manufacturing process to prevent the binder from blocking the pores. In preferred embodiments a mixture of different desiccants is used and a particle suspending agent keeps the particles well-mixed so that the desiccant particles in the coated substrate will be as well-mixed as possible. The suspending agent may also function as the pore-clearing agent. A pH-adjusting agent may be used to control the pH of the coating if the binder or another of the coating is pH-sensitive.
