Process and apparatus for interbed injection in plate reactor arrangement

A process and apparatus for indirectly exchanging heat with narrow channel in a heat exchange type reaction zone uses manifold space to interconnect the common ends of channels and to provide controlled distribution of additional reactants. The invention simplifies the operation and construction of the heat exchanging type reaction zone by directly communicating reaction channels and/or heating channels with a manifold located at the end of the channels. The manifold can provides the extra function of mixing additional reactants. The invention promotes simplified intermediate injection of reactants over tube and shell heat transfer arrangements that have been used for similar purposes. Improved process control has particular benefits for exothermic reactions. The narrow channels are preferably defined by corrugated plates. The reaction channels will contain a catalyst for the promotion of the primary reaction.

The spiral is provided in the form of a multiple or multi-channel spiral by arranging a plurality of flow ducts. In particular, the spiral heat exchanger consists of two multiple spirals with opposed directions of current.

Plate type heat exchanger

Primary surface heat exchanger

An all purpose primary-surface heat exchanger, comprising an array of parallel channels formed and bounded by thin heat conductive walls, at least one wall of which has on at least a portion of its surface substantially uniformly disposed unidirectional truncated conical wall-supporting projections formed from the wall. The projections are arranged so as to mate with and to abut supportingly against corresponding wallsupporting projections of a similar adjacent wall. The walls, so arranged, are sealed at the wall edges in a manner to form and isolate alternate enclosed channels from intervening open channels so that the alternate channels may contain and conduct a first fluid, and the intervening channels may contain and conduct a second fluid at a different temperature, thereby effecting heat exchange between the fluids.

Thermal transfer care

A heat exchanger for transmitting thermal energy from one moving fluid to another of the type having a casing housing a thermal transfer core, the core including a folded sheet of heat conductive material defining adjacent fluid flow passages, the individual fold sections of the sheet having a multiplicity of pairs of dimples formed therein, each dimple pair including a raised dimple and an adjacent depressed dimple, the height of each dimple being substantially equal to one-half the width of the fluid flow passages. The dimple arrangement provides a relatively low pressure drop for the fluids passing through the fluid flow passages.

Plate type heat exchangers

A heat exchanger has a number of corrugated plates arranged one above the other with spaces between them. The two fluids between which heat is to be exchanged flow in counter-flow relationship in alternate spaces between the plates. The plates are arranged so that the flow passages between them are of constant width across the whole flow-section of the heat exchanger, and spacers are mounted on some of the corrugations to maintain the plates the correct distance apart.

Apparatus, process and system for tube and whip rod heat exchanger

An apparatus, thermal storage system and method for heat exchange using a tube-type heat exchanger. A rod (24) or rods (24, 24') are propelled to move over the inner surface (7) of the tube (1). The moving rod (24) is in contact with a first process liquid which is adjacent the inner surface (7) as a falling film or by flooding the interior of the tube (1). The flooded mode is particularly useful where the tube (24) is non-vertical or the heat exchanger is used to make an ice slurry for HVAC systems serving high-rise buildings. Multiple such rod (24) and tube (1) assemblies are operated simultaneously using a drive plate (22) powered to execute an orbital motion in a plane generally orthogonal to the rods (24, 24'). In one form the plate (22) is coupled via a crank (40) to equiangularly spaced rods (24, 24') in each tube (1). The rods (24, 24') are preferably mounted to be movable radially, for example suspended through holes (23) in, and driven by, a plate (22) to execute an orbital motion or at recesses (49, 49') in the rod (24) in radially directed slots (48, 48') in an arm (46) rotated by a tube-mounted crank (40).

The present invention relates to a non-Diesel motor and a drain pump having the same. In the present invention, the stator is coupled to the inside of the sealed housing, while the rotor is installed outside the housing, thereby preventing the washing water from flowing into the inside of the pump. Also, as the first and second housings are hooked together, the housing can be easily assembled. Further, since the guide ribs are formed on both sides of the hook protrusion, the fastening operation of the housing can be easily and safely performed. In addition, the stator can be stably supported by forming the support protrusion for supporting the stator in the axial direction. Further, it is possible to prevent invasion of the washing water as the stator is coupled to the inside of the sealed housing. Further, since the sealer is provided outside the rotor receiving groove, it is possible to effectively prevent the detachment of the rotor and to prevent the washing water or dirt from entering the rotor.

Patent FR2095268B1

A heat exchanger for use in the flue gas exhaust system of a self-cleaning gas cooking oven in the form of a large square-cornered corrugated panel that is collapsed from the sides in the plane of the panel to create two intermeshed series of triangular shaped pipes where one series of alternate pipes carry hot flue gases while the opposite series of alternate pipes carry inlet air for transferring some of the heat of the flue gases to the ambient air. The front face of the heat exchanger that is turned toward the oven operates hot, while the back face of the heat exchanger operates relatively cool to reduce heat losses to the outside. Sealing means close both the top and bottom ends of the pipes. Inlet and outlet openings are formed in the front and back faces of the unit near the top and bottom.

Edge-hanging orbital rod support and drive for vertical tube-type heat exchanger

A tube type heat exchanger has a low wear support and drive for a whip rod (12) that orbits over the inner surface of the heat transfer tube (14) to spread a process liquid into a thin falling film. The support and drive includes a conical thrust bearing (18) near the upper end of the rod. An edge (18b) of the thrust bearing engages and rolls over a circular rim bearing surface (20). A stem pin (28) axially aligned with the rod extends upwardly over the rod and through a circular hole (30) in an orbiting drive plate. In one form, the rim bearing surface is formed on the upper edge of the tube, or on the upper edge of a generally cylindrical bearing (15) secured on or over the tube. The thrust bearing is secured between the rod and the stem. A stop disc (32) carried on the stem pin limits the fall of the rod in the tube when the orbiting stops. In another form, the rim surface is formed on a cylindrical collar (38) secured on the upper surface of the drive plate surrounding the drive hole and the thrust bearing is formed on the lower face of the stop disc fixed on the stem.
