Description
Technical field
This utility model relates to the waste steam condensation equipment that a kind of vaporising device is supporting, and specifically a kind of low pressure is steamed
Vapour partition condensing unit.
Background technology
The condensing plant of exhaust steam produced by vaporising device end, current art is all between mixing condenser, or tubulation
Wall condenser.Mixing condenser is because steam and cooling water directly contact, and heat transfer, condensation effect are good, and simply, cost is low for equipment.
Partition condenser is because being partition-wall heat transfer, and again because being low temperature, Low Temperature Difference heat transfer, heat-transfer effect is poor, and the heat transfer area of needs is huge
Greatly, cost is high.Therefore partition condenser is normally only used for valuable solution and reclaims condensation.
Occur in that the condenser of ecological requirements in the recent period: the indirect steam of some large-tonnage evaporation solution is mixed with nuisance
Matter, is absorbed by recirculated water in condensation by mixing, and recirculated water is during entering the circulating cooling of air cooling compressor, can be dissolving in
Harmful substance therein discharges into air, causes atmospheric pollution.In the case of society is to environmental requirement increasingly stringent, environmental protection
Call a kind of new, efficient partition condenser, meet the needs of large-tonnage evaporative condenser.It is cold that large-tonnage vaporising device needs
Solidifying quantity of steam, between the most several tons to tens tons, and the temperature difference between the exhaust temperature condensed and cooling water is the least, special
It it is not summer.Making partition condenser with common tubular heat exchanger, owing to heat transfer coefficient is little, the heat transfer area of equipment needed thereby is very
Greatly.Wanting to make partition condenser with efficient plate type heat exchanger, but do not have broad low-pressure steam passage, this is not have up to now
The reason of large-tonnage partition condensation is made with plate type heat exchanger.Because condenser condensation is evaporation tail gas, it is that the secondary of end steams
Vapour, end indirect steam pressure is the lowest, and steam specific volume is very big, and the steam of per kilogram has the volume of about 20 cubic metres, condenser
In, to pass through, condense the low-pressure steam of tens cubic metres each second, the air intake cross section of common plate type heat exchanger is the least, it is impossible to
Pass through.
