RU16399U1 - PARTIAL CAPACITOR SEPARATOR FOR HEAT AND MASS EXCHANGE PROCESSES - Google Patents

Description

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

A horizontal shell-and-tube condenser is known, containing a bundle of pipes fixed in a grating with the formation of vertical channels for steam passage, annular grooves are made on the surface of the pipes for drainage of condensate into a steam trap. located on the bottom surface of each pipe in the form of a straight channel along the generatrix of the pipe, (see US patent 3170512.1965. F28F9 / 08)

A shell-and-tube condenser is known in which the steam trap is made in the form of a rib inclined to the condensate drain pipe, the lower slice of which is placed in vertical channels for steam passage. (see Av.St. USSR 1044939, F28F9 / 00.1982r.

However, in the known devices, the low efficiency of the process due to entrainment of the liquid phase.

The closest technical solution to the proposed one is the partial condenser-separator selected by the applicant for the prototype, which includes a housing with gas, steam and condensate inlet and outlet devices, a condensate collector and heat-exchange elements installed in the housing with cooling agent inlet and outlet pipes. (see Av.St. CCCP1052831, F28F9 / OOJ982r.)

However, the known device is characterized by a low heat transfer coefficient, insufficient turbulence of the gas and steam flow.

resistance.

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

The solution to this problem is achieved by the fact that the partial condenser, including the housing with the input and output devices of gas, steam and condensate, a condensate collector and heat exchange elements installed in the housing with the inlet and outlet of the cooling agent, according to the utility model

a screw partition, heat-exchange elements are made in the form of a corrugated shell mounted coaxially relative to the housing with the formation of a circulation cavity, the cavity being hydraulically connected to the inlet and outlet of the cooling agent, the gas outlet device is made in the form of a perforated pipe mounted coaxially to the housing axis inside the corrugated shell, a helical partition is installed between the perforated pipe and the corrugated shell.

It is advisable to perform the pipe with perforation, the area of which increases to the condensate collector. The corrugated shell should be provided with a layer made of capillary-porous material with high thermal conductivity, the screw partition should be made with a variable pitch, increasing towards the condensate collector.

In FIG. 1 is a schematic longitudinal sectional view of a capacitor-separator.

FIG. 2 is a section along aa of FIG. 1

The partial condenser-separator comprises a housing with devices for introducing 2 gas-vapor mixture and outlet 3.4, respectively, of condensate and non-condensing gas, nozzles 5.6, respectively, for introducing and discharging a cooling agent, a corrugated shell 7 mounted coaxially relative to the housing to form a circulation cavity 8, hydraulically associated with the nozzles 5.6, the device 9 of the gas outlet, made in the form of a perforated pipe mounted coaxially to the axis of the housing inside the corrugated shell, screw partition 10, inserted between a perforated pipe and a corrugated shell.

It is advisable to perform the pipe with perforation, the area of which increases to the condensate collector. The corrugated shell is provided with a layer made of a capillary-porous material with high thermal conductivity, screws /) SEPARATE with a variable pitch, increasing to the condensate collector 11.

The partial condenser-separator operates as follows / The mixture of hydrocarbon vapors and non-condensing gases tangentially enters through the input device 2 and then moves in a swirling flow through the circulation cavity between the corrugated shell 7 and the central perforated pipe. Hydrocarbon vapors condense on the cooling surface of the corrugated shell. Heat Phase Transformation

d

during condensation, it is transferred to the cooling agent circulating inside the cavity 8. The liquid formed as a result of steam condensation moistens the capillary-porous material with which the shell is coated and flows through the capillary channels onto the screw surface of the partition 10, which serves as a guide and an additional function of the condensate drain. Under the action of centrifugal force, the liquid vapor is discarded to the surface of the corrugated shell. where they are intensively cooled and condensed. Further, the liquid flows down the screw baffle 10 into the condensate collector 11 and is discharged from the housing through the pipe 6.

The implementation of the pipe with perforation, the area of which increases to the condensate collector, leads to a decrease in the pressure loss of the non-condensing gas.

The implementation of the screw partitions with a variable pitch increasing to the condensate collector leads to an intensification of the condensation process.

The proposed partial condenser-separator generally intensifies the heat transfer process.
