Energy saving analysis of steam trap

Trap stanza to steam produced by the benefits of energy conservation, high temperature condensate pump back pressure recovery of energy-saving benefit, water-saving efficiency analysis of the steam trap. At present, the enterprise equipment used on trap type is various, can be divided into two categories: thermodynamic model and mechanical model, the use of general effect is not ideal. Thermodynamic trap, because on the structure and movement theory, water, steam is a row, misoperation, in the absence of water will also exhaust steam, waste a lot of raw steam, leakage rate was 6% ~ 10%, easy damage, short service life. The mechanical type of trap ( Such as leverage all floating ball, inverted bucket, etc. ) Also due to structural reasons and easy to wear and tear, cause steam leakage, generally in 3% ~ 6%. The new type high efficiency and energy saving without pump back pressure steam trap by the national testing center testing, trap the leakage rate & le; 0. 1%, even by 1%, more than any other type of steam trap section average above 5%. How much steam equipment consumption, in general, that is, how much can produce water. No pump back pressure recovery of high temperature condensate recovery more than 95%, its temperature can reach 85 ℃ above, if the high temperature of 85 ℃ water recycling used hot water to the boiler room of soft water tank or place, its energy-saving benefit can through thermodynamic calculation to know: 1 of the 20 ℃ cold water heated to 85 ℃ needed to 0. The amount of saturated steam 2 mpa. Q = Q put ( Put the Q = Q + Q sensible heat, latent heat of Q of latent heat to 0. 2 mpa saturated steam condensation for the temperature of the heat released by the saturated water; Q sensible heat to 0. 2 mpa saturated water at the temperature to 85 ℃ water heat energy that is released. ) 。 m1× c× 〔（ 273 + 85) - ( 273 + 20) 〕报; 4. 187 = m2× c′ +m2× c× 〔（ 273 + 120) - ( 273 + 85) 〕报; 4. The 1000 & 187 times; 1× （ 358-293) × 4. 187 = m2× 〔2202 + 1报; （ 393-358) × 4. 187〕m2 = ( 1000× 1× 65× 4. 187). / ( 2202+1× 35× 4. 187). = 116 ( Kg) The 1 of the 20 ℃ cold water heated to 85 ℃ should be 0. 2 mpa saturated steam 116 kilograms, in turn, recycling one ton of 85 ℃ high temperature condensate can save 0. 2 mpa saturated steam 116 kilograms. Recycling be precious of high temperature condensate water softening, recovery rate can reach more than 95%, not only contains a large number of available sensible heat, but also can largely reduce the boiler water and production water, but also reduce the emissions of sewage. Can be seen from the above analysis of energy saving, water saving benefits, was ignored by many businesses before section of steam and high temperature condensed water recycling issues, is a great article to do, is of great potential can be dug. For high temperature condensate pump back pressure automatic lifting technology development and application, has opened up for the enterprise and a road to energy saving, water saving, its efficiency is able to see and touch, is real net income.
