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.

Known horizontal shell-and-tube condenser containing a bunch of pipes fixed in the lattice with the formation of channels for the passage of steam, on the surface of the pipes made channels for drainage of condensate into the steam trap. (see, for example, US patent No. 3170512, F28F 9/08, 1965)

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, for example, patent RU No. 16399, F28F 9/00, 2001)

Known devices are characterized by low process efficiency.

The technical problem to which the utility model is directed is to increase the efficiency of the process 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, ka is made with corrugations of triangular shapes and the blades of a helical partition are made with upward bent edges.

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 contains a housing 1 with nozzles 2, 3, 4, 5, 6 of the inlet and outlet of gas (steam), condensate and a cooling agent, a corrugated shell 7 made with triangular corrugations with a layer of capillary-porous material with high thermal conductivity, coaxially located relative to the housing with the formation of an annular channel 8, a perforated pipe 9 placed in it, a screw baffle 10 installed between them, a condensate collector 11, and the screw baffle blades are made with tognutymi up edges.

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 nozzle and moves in a swirling flow through an annular channel formed between triangular corrugations and a central perforated pipe made with a variable flow cross section. A cooling agent is fed into the channel formed between the surface of the shell with triangular corrugations and the wall of the body. Hydrocarbon vapors condense on the cooled surface of the shell. The heat of phase transformation during condensation is transferred to the cooling agent. The liquid formed as a result of steam condensation wets the inclined surfaces of the corrugations without flooding the lower surfaces of the corrugations, penetrates the capillary-porous material of the shell and enters through the capillary channels on the surface of the blades of the screw partition. The liquid is retained on its surface due to the presence of upwardly bent edges, flows down the film along the inclined surface of the blades and enters 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 combination of the claimed features intensifies the heat transfer process and improves the conditions of condensation.
