Description
Technical field
The invention belongs to heat-energy recovering apparatus technical fields, and in particular to a kind of Boiler Steam condensed water thermal energy recycling dress
It sets.
Background technique
It is 70 DEG C~100 DEG C condensed waters that steam, which can generate temperature through drain valve in use, and enthalpy is higher, in line wave
Take, gas fired-boiler supply steam efficiency and saving combustion gas energy consumption will be improved by recycling.
It is directed to there are two types of the recycling of gas-steam boiler steam condensate thermal energy in the prior art, one kind is directly recycling, separately
It is outer a kind of for the embedded plate heat exchanger heat exchange recycling thermal energy methods of tank body.It is specific as follows:
Steam condensate: being directly recycled to boiler feedwater case by direct recovery method, directly feeds pot by boiler feed pump
Furnace, steam condensate have serious corrosivity and condensation impurities in water more in acid, and direct use will cause boiler, steam
Pipeline heavy corrosion, iron ion is more in condensed water, and muddiness influences electrode level and is counted as using and observe.
Condensed water has the following in acid reason:
(1) contain magnesium bicarbonate and calcium bicarbonate impurity in the water before handling, after sodium ion exchange resin is handled all
It is converted into sodium bicarbonate.
(2) sodium bicarbonate, which generates sodium hydroxide and carbon dioxide gas, sodium hydroxide in pot reaction in furnace, can make storage heater
With boiler water in alkalinity.
(3) carbon dioxide gas physical efficiency is dissolved in saturated vapor condensation water part, so that saturated vapor condensed water
PH is reduced.
(4) carbon dioxide can largely dissolve in condensed water, finally make condensed water in acidity.
Direct recoverying and utilizing method, the water treatment facilities without especially mature processing condensed water domestic at present, makes for a long time
With boiler safety in utilization is reduced, boiler service life is reduced.
Tank body embeds plate heat exchanger heat exchange and recycles thermal energy methods: steam forms high temperature after being subjected to heat processing unit heat exchange
Condensed water in condensate water collecting to condensed water water collect tank, then is embedded in heat exchanger in tank body and is exchanged heat, and sewage is straight after heat exchange
Row reaches the recoverable effect of heat.Disadvantage: pot type volume is big, and heat exchange area is small, and return water resistance is big, and uneven heating is even, and thermal energy returns
Low efficiency is received, precipitating sludge cleaning is difficult, and sewage effluent temperature height causes drain pipe deformation etc..
