SU821896A1 - Direct-flow mixing condenser of juice vapours - Google Patents

Description

one

The invention relates to a power system, in particular to the construction of a mixing capacitor, and can be used in the food, chemical and other industries.

Known direct mixivacija juice vapor condenser, containing two successively connected in a couple of steps, each of which is located in the upper part of the water distributor. The upper section is designed to heat pure water from a natural reservoir (river, lake, well) required for technical needs and partial condensation of steam, and the lower section is used to condense the remaining mass of steam with recycled water repeatedly used in production. Non-condensable gases are discharged from the bottom of the rammer section of the condenser f

The disadvantage of this condenser is that the tangential entry of steam into the film (upper) part of the apparatus causes a large hydraulic resistance, which reduces the efficiency of heat exchange. In addition, a portion of the clear water film is broken free of charge and carried to the second (straight through) section of the condenser, which entails an increase in consumption; clean water.

The purpose of the invention is to intensify heat and mass transfer and prevent the entrainment of water.

To achieve this goal, the first section along the pair is provided with a plate in the form of a hollow truncated cone,

0 installed under the water distributor in the center of the hull and facing the latter with a smaller base.

The drawing schematically shows a flow mixing capacitor.

Condense op consists of two successively connected in a couple of steps - upper and lower, enclosed in a common cylindrical body 1 and interconnected by a pipe

0 2. In the upper part of the condenser there is a steam supplying nozzle 3, under which a clean water distributor 4 is installed with a nozzle 5 for supplying it. The axis of the housing under the water 5 distributor 4 installed plate 6 in the form of a hollow truncated cone, facing the latter with a smaller base. Pipe 7 is designed for removal of heated clean water.

0 NC upper stage. In the lower stage of the installed water distributor 8 circulating water with a pipe 9 for its supply. Overflow cone plates 10 and 11 and a pipe 12 for removal of non-condensable gases are installed under the water distributor 8, the pipe 13 serves to drain the heated circulating water from the lower stage. The capacitor works as follows.

Steam enters the condenser body 1 through the nozzle 3. Clean water for technological needs by the nozzle 5 is supplied to the water distributor 4, from which the swirling turbulized curtain is distributed over the entire condenser cross section. When crossing the liquid curtain, some of the vapor condenses on it and the rest of it moves in the same direction as the water. The plate 6 serves to direct (drop) the water into the peripheral annular water receiver, from where it is diverted by the nozzle 7 to the consumer. Circulating water through the pipe 9 is supplied to the water distributor 8. After being distributed over the entire cross section of the lower condenser stage, the water is drained onto conical plates 10 and 11 and discharged from the condenser through pipe 13. The uncondensed part of the steam from the upper stage through patrubo 2 enters the lower stage of the condenser, crosses the water curtains of recycled water and condenses on them. Non-condensing gases are discharged from the condenser by a pipe 12.

the mutual arrangement of the nozzle 3 and the conical plate b reduces the resistance of the vapor – gas path, eliminates the rectilinear movement of steam and pure water and the ingress of the latter. to the lower stage of the condenser, as a result of which the heat and mass treatment is intensified and the efficiency of the device increases.
