摘要:
Device for removing acidic and injurious gases such as a sulphur dioxide gas and a hydrogen sulfide gas or acid mist from the air comprising a plurality of absorption plates, spacing means positioned for maintaining the absorption plates apart to form a plurality of layers so as to pass air through the space between said layers. The absorption plates are hygroscopic and made of a material such as paper, asbestos paper, cloth or unwoven textile which is impregnated with an alkaline substance selected from the hydroxides and carbonates of alkali metals and alkaline earth metals such as potassium, sodium and calcium, and a hygroscopic wetting agent such as glycerine, ethylene glycol and propylene glycol so that the acidic and injurious gases or the acidic mist are neutralized by said alkaline substance. The device also comprises a plurality of such absorption plates and interposition plates. The interposition plates are interposed in the space between said absorption plates so as to guide two directional flows of air alternately into said space. As a further embodiment, the device comprises a plurality of said absorption plates and a heat-exchange element placed on the air-inlet side of said absorption plates. The heat-exchange element comprises a plurality of partition plates, and spacing means positioned for maintaining the partition plates apart, to form a plurality of layers so as to guide two directional flows of air alternately into the space between said layers. The interposition plates and the partition plates are made of the same material as used in the absorption plates.

An apparatus for continuously forming an impregnated paper web with corrugations or pleats extending diagonally to the edges of the web in an elongated form movable along a straight path and formed with grooves extending in the same diagonal direction and entered by projections from a forming head rotatable about an axis parallel to said diagonal grooves, said projections being disposed in such a manner that at least one projection always retains a corrugation or pleat formed by the same in the paper web pressed against the form so as to prevent a sliding back movement of the web during formation of the next following corrugation.

In a device for causing contact between horizontally-flowing gas and vertically-flowing liquid, a stack of corrugated contact plates in face-to-face contact and having their corrugations inclined to the horizontal plane. Alternate plates of the stack are inclined upwardly in the direction of gas flow and the intermediate plates are inclined downwardly at the same angle of inclination. The upwardly-inclined corrugations have a smaller radius of curvature than the downwardly inclined corrugations. The heights of the respective corrugations are preferably equal and the radius of curvature in the upwardly-inclined corrugations is less than the height of said corrugations.

A sheet of material having a succession of spaced alternate protrusions and recesses, the walls of each such protrusion and recess being composed exclusively of non-rectangular elementary surfaces joining each other in an undulatory manner at the ridges of said protrusions and recesses along a single line having a plurality of points at which it changes direction to form a plurality of undulations and at each of which points border lines of at least four of said elementary surfaces converge, said surfaces being ruled in a direction extending from one ridge line to another, the sum of the angles formed on said surfaces between said border lines at each of said points being equal to 360.degree..

A moisture adsorbent packing is formed as a laminated cellular structure of paper in which the pores of the paper have been filed with an inorganic moisture adsorbent substance, the packing being strengthened and reenforced using some minor hard resin coating at the cellular inlets and outlets of the packing without, however, coating of the moisture adsorbent surfaces.
摘要:
A contact apparatus for liquid and gas, primarily used in air conditioning systems, which includes a contact body composed of first and second sets of corrugated sheets arranged with the sheets of the first set disposed alternately with the sheets of the second set. The corrugations of the sheets provide channels for passageways which penetrate the contact body from edge to edge, with both horizontal and vertical components of direction. A liquid distributing means is disposed over the top edge of the contact body. The channels thus formed are simultaneously passed by a flow of the gas in one direction and by the liquid in either counterflow or crossflow directions. The corrugations of the first set of sheets cross the corrugations of the second set of sheets, at an acute angle in the range of from 20* to 80*. The corrugations of the first set of sheets have a greater inclination to the horizontal plane of the contact apparatus than the corrugations of the second set of sheets; and the corrugations in the first set of sheets are inclined upwardly in the direction of the gas flow; the bisector of the angle of the corrugations of the respective sheets inclining downwardly opposite to the direction of gas flow with respect to the horizontal plane of the contact body; whereby to counteract an undesirable lateral displacement of the liquid stream caused by the gas flow, and causes the liquid to be distributed uniformly and causes evenly over the sheets.

There is provided a liquid-gas contact device which has a liquid distributor (2) provided in the upper portion of the device, a liquid collector (3) provided in the lower portion of the device and an internal structure between the liquid distributor (2) and the liquid collector (3) which defines a plurality of flow paths. The liquid-gas-contact device includes a column packing (5) constituting the internal structure made of a plurality of column packing constituting elements (6) each of which extends vertically in parallel to each other in a non-contact state and in a non-contact state with an inner wall of the device, a plurality of adaptors (4) connecting the liquid distributor (2) with the column packing (5) for supplying liquid from the liquid distributor (2) to the column packing (5), and a plurality of collectors (7) connecting the column packing (5) with the liquid collector (3) for supplying liquid from the column packing (5) to the liquid collector (3).
摘要:
A gas liquid contact body for use in a gas liquid contact apparatus is disclosed which consists of at least first and second sets of corrugated sheets with the sheets in the first set being disposed alternately with the sheets of the second set. The corrugations in the first set of sheets extend vertically in the contact body and the corrugations in the second set extend at an angle to the corrugations of the first set. The passageways formed between the inclined corrugations and the vertical corrugations serve to distribute air and water evenly through the contact body and avoid clogging thereof.
