Description

The utility model relates to heat and mass transfer equipment and can be used in chemical, heat power and other industries for condensation of vapors, as well as for cooling vapor-gas mixtures and removing the liquid phase during vapor condensation.

A horizontal shell-and-tube condenser is known, containing a bundle of pipes fixed in a grate with the formation of channels for steam passage, a condensate collector and heat-exchange elements installed in the housing with inlets and outlets of a cooling agent (see, for example, ed. Certificate No. SU 1044939, F28F 9/0, 1982)

The closest technical solution to the proposed one is the condenser-separator selected by the applicant for the prototype heat and mass transfer processes, comprising a housing with nozzles for the input and output of gas (steam), condensate and a cooling agent, a corrugated shell, coaxially located relative to the housing with the formation of an annular channel, made with a layer from a capillary-porous material with high thermal conductivity, a perforated pipe placed in it in the center, a screw partition between them and rnik condensate (see., e.g., Patent RU №16399, F28F 9/00, 2001 YG)

Known devices are characterized by low process efficiency due to insufficient turbulization of the gas-vapor stream.

The technical problem to which the utility model is directed is the intensification of heat and mass transfer by improving the conditions of condensation and heat transfer.

The solution to the technical problem is achieved by the fact that the condenser-separator for heat and mass transfer processes, comprising a housing with gas and steam inlet and outlet nozzles, condensate and a cooling agent, a corrugated shell, coaxially located relative to the housing with the formation of an annular channel, made with a layer of capillary-porous material with high thermal conductivity, a perforated pipe placed in it in the center, a screw partition installed between them and a condensate collector, according to a utility model, corrugation The oval shell is made with a corrugated surface.

The drawing schematically shows a longitudinal section of a condenser-separator for heat and mass transfer processes.

The condenser-separator for heat and mass transfer processes includes a housing 1 with nozzles 2, 3, 4, 5, 6 of the input and output of gas (steam), condensate and a cooling agent, a corrugated shell 7, made with a corrugated surface, coaxially located relative to the housing with the formation of an annular channel 8, a perforated pipe 9 placed in it in the center, a screw partition 10 installed between them, a condensate collector 11,

Condenser-separator for heat and mass transfer processes works as follows:

A mixture of hydrocarbon vapors and non-condensable gases enters through a tangentially located pipe and moves in a swirling flow through a complex channel system with a variable flow cross section formed between the corrugations and the central perforated pipe. In the channel formed between the surface of the shell and the wall of the housing serves a cooling agent. Hydrocarbon vapors condense on a cooled shell surface made with a corrugated surface. The heat of phase transformation during condensation is transferred to the cooling agent. The liquid formed as a result of steam condensation wets the corrugated surface of the corrugations, penetrates into the capillary-porous layer and enters through the capillary channels on the surface of the blades of the helical partition. The liquid flows down the film from the surface of the blades into the condensate collector. Then the fluid is discharged from the housing through the nozzle. Non-condensing gas passes through the perforation of the pipe and is discharged from the body through the pipe. The implementation of the corrugated shell with a corrugated surface causes local pulsations of the vapor-gas flow, which contributes to the efficient use of the heat transfer surface and improves the conditions of condensation.
