Description
Technical field
The utility model belongs to residual heat using device, particularly heats the device of cogeneration unit condensate water.
Background technology
Carbon calciner produces a large amount of high-temperature flue gas in calcination process, after the production forge the back burnt temperature can reach 300 ℃.To forge the burnt cooling in back in order giving, to need the configuration Water Jacket in Calciner to forge the burnt cooling in back to what calcining furnace was discharged, the cooling water in the water jacket can reach 60-70 ℃, and these water are discharged after the cooling tower desuperheat enters water jacket again recycles.Because the high big cost height of cooling tower capacity that needs of water temperature.Steam turbine condensate water in the carbon calciner afterheat generating system directly enters oxygen-eliminating device by condensate pump and carries out deoxygenation: water is atomized by sprinkling equipment, with the heating steam heat exchange, moment is heated to saturation temperature under the level pressure with water, make in the saturation temperature water of gas under level pressure in the water to be extruded out, discharge by oxygen discharging door.Because it is low to enter the condensate temperature of oxygen-eliminating device, needs a large amount of steam in the oxygen removal process, these steam extract in the middle of female pipe of main steam or steam turbine, have in fact reduced the quantity of steam that is used to generate electricity.
The utility model content
In order to overcome the deficiency that high-temperature water that existing Water Jacket in Calciner discharges is not fully utilized, the purpose of this utility model provides a kind of device that utilizes Water Jacket in Calciner water heating cogeneration condensate water, this utilizes the device of Water Jacket in Calciner water heating cogeneration condensate water not only can utilize the heating of Water Jacket in Calciner water to improve the temperature of coagulating water saving that enters oxygen-eliminating device, and can reduce the load of cooling tower.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device of Water Jacket in Calciner water heating cogeneration condensate water that utilizes comprises Water Jacket in Calciner, oxygen-eliminating device, condenser, it is characterized in that: the primary fluid inlet that connects heat exchanger at the Water Jacket in Calciner delivery port through pipeline, the outlet of heat exchanger primary fluid connects cooling tower through pipeline, condensate pump connects heat exchanger secondary heating agent inlet through pipeline, and the outlet of heat exchanger secondary heating agent connects the oxygen-eliminating device water inlet through pipeline.
Described heat exchanger is that calandria heat exchanger, tubular heat exchanger, shell-and-tube heat exchanger, plate type heat exchanger or other are applicable to the heat exchanger of water water heat exchange.
Water jacket water recycle circuit is in the utility model: Water Jacket in Calciner → heat exchanger primary fluid runner → cooling tower → calcining furnace feed pump → Water Jacket in Calciner.
The glide path of condensate water is: condenser → condensate pump → heat exchanger secondary heating agent runner → oxygen-eliminating device → feed pump → waste heat boiler.
The utility model utilizes cycle down warm water heat in the calcining furnace, can make condensing water temperature be promoted to 47 ℃ by 37 ℃ by carrying out heat exchange with condensate water, reduces deoxygenation heating steam amount, improves the steam turbine quantity of steam and exerts oneself.Two 3000KW generating sets, condensate water output are 24 tons/hour, mark 858 tons in coal according to improving 10 ℃ of calculating of condensing water temperature, can save every year to amount to.The simple investment of device structure is little, is the effective measures of energy-saving and emission-reduction, and good economic benefit and environmental benefit are arranged.
