Description
Technical field
The utility model belongs to Boiler Steam condensate water reclaimer, is specifically related to the closed circuit recovery system of a kind of steam condensate.
Background technology
The discharge of the condensate water that steam closed circuit circulatory system, steam produce after heat release is flowed out by drain valve naturally by self gravitation generally speaking, or extrudes by the steam pressure of heat exchanger.Condensate water in the heat exchanger being discharged as early as possible do not retain, to reach the purpose that promotes heat exchange temperature, all is at the occasion adjunction by-passing valve that uses drain valve under most of situation.Add connect by-passing valve after, hydrophobic effect has been got well, but the thing followed is seriously to leak vapour, causes a large amount of energy wastes.
Common steam condensate processing mode in the actual condition:
1, open type reclaims.Steam condensate is transported to open water tank by reclaim line, by cooling, aspirates to boiler water supply then by the boiler water supply pump.
Advantage: system is simple, does not influence production efficiency.
Shortcoming: thermal waste is serious, the boiler water pump serious cavitation erosion
2, adopt reciprocating type energy-saving pump to carry out closed circuit recovery.Steam condensate is carried out closed circuit recovery by reclaim line by the reciprocating type energy-saving pump of employing, use as boiler water supply.
Reciprocating type energy-saving pump operation principle: the flow of reciprocating pump and pressure head are irrelevant, and be relevant with pumping cylinder size, piston stroke and reciprocal time.
Advantage: system is simple, and certain energy-saving effect is arranged.
Shortcoming:, have a strong impact on production efficiency because draining system is not smooth.Equipment dependability is low, and consumable accessory is many, if there is impurity will cause four check valves on the reciprocating pump malfunctioning in the water, thereby makes it ineffective, and then influence is produced.
Reciprocating pump formula energy-saving equipment all is serially connected in the water return pipeline in use, and it is hydrophobic to take advantage of a situation by the condensate water self gravitation in some occasion, and drain valve leaks under the low situation of vapour, and result of use still is passable, then obviously descends leaking the big occasion effect of vapour.The crux of problem is: its workload is pumping cylinder size, piston stroke and reciprocal time, and the meaning i.e. swept volume of the cylinder of this pump is a fixed number.That is to say that media such as water that it per hour can equate pumping cylinder size, piston stroke and reciprocal time at most or vapour are delivered to boiler.The front was said, leaking the low occasion of vapour rate, only transmitted condensate water and should satisfy the demand.But since on our production line the occasion of using drain valve all adjunction bypass, it is big and quantity is non-constant therefore to leak vapour.There is stream-liquid two-phase flow in the water return pipeline, saturated vapor density under 6 atmospheric pressure approximately is about 2kg/ m3, and the density of condensate water is 1 kg/ m3, that is to say, reciprocating pump is used for the words of delivering vapor condensate water, if per hour carry 20 kilograms of condensate water, in pipeline under the situation of stream-liquid two-phase flow, the efficient of reciprocating pump is very low so.Owing to can not in time transmit, condensate water will accumulate in the heat exchanger, though cause the heat exchanger gauge pressure not little, actual temperature does not reach requirement, thereby has influenced production efficiency, causes energy waste simultaneously.
3, adopt the strong pumping formula to reclaim machine
Steam condensate strong pumping equipment is present emerging a kind of reclaimer, and its performance has mainly utilized strong pumping to form the low pressure principle, steam condensate is reclaimed use as boiler water supply.
Technical disadvantages:
(1) poor for system's adaptive faculty of complexity, during particularly to steam condensate backwater amount instability.
(2) dynamical system is a rated frequency, and power consumption is big.
(3), thereby can only lean on the ration of increase equipment to reach the required steam condensate processing of actual condition because the technical bottleneck that exists in the equipment self research and development can't be handled the recovery of large-tonnage condensate water at present.
Summary of the invention
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, provides a kind of steam condensate closed circuit recovery system, condensate water organic efficiency height, and energy consumption is low, and reasonable in design, compact conformation can be realized the utilization of steam resource circulation.
The closed circuit recovery system of the steam condensate that the utility model provides, comprise booster jar, main work jar, connecting line, booster jar is connected with heat exchanger by tube connector, pipeline between booster jar and the heat exchanger is provided with stop valve, booster jar is communicated with main work jar by tube connector, main work jar top is provided with steam (vapor) outlet, and the bottom is provided with the condensate water outlet.It also comprises safety valve, and described safety valve is arranged on the main work jar.Pressure in the main work jar is lower than the pressure in arbitrary heat exchanger.It also wraps high-temperature pump, and described high-temperature pump exports by the condensate water that tube connector one end connects main work jar, and the other end connects boiler.The steam (vapor) outlet of main work tank top connects vapour system by tube connector.
The closed circuit recovery system of the steam condensate that the utility model provides, its operation principle is: regulate and being connected of heat exchanger with stop valve, when being lower than setting value, opens heat exchanger efficiency stop valve, reclaim line is passed through stream-liquid two-phase flow, with condensed water in high temperature in a plurality of heat exchangers and high-temperature steam, be recycled to the closed circuit recovery system of steam condensate.Condensed water in high temperature and high-temperature steam at first enter booster jar, in booster jar, carry out the vapor-liquid separation first time, enter main work jar then, in main work jar, the secondary exhaust steam enters vapour system by the high-temperature steam outlet, condensate water is flowed out by the condensate water outlet of bottom under the self gravitation effect, is recycled to boiler through high-temperature pump and recycles.Main work tank top also is provided with safety valve, with pressure control within the specific limits, guarantees that the pressure in the main work jar is lower than each heat exchanger, and safety valve was opened when pressure was higher than setting range, to guarantee hydrophobic the pressure.
Backwater is forced through height and will causes heat exchanger ponding when a main jar operating pressure is higher than other gas utilization units, by booster jar main work jar is got back in the condensed water in high temperature pressurization of reclaiming in order to solve this difficult problem.
The closed circuit recovery system of the steam condensate that the utility model provides, its beneficial effect is, adopt booster jar that high-temperature steam in the heat exchanger and condensed water in high temperature common network are reclaimed, and then enter main work jar and carry out the secondary vapor-liquid separation, the secondary exhaust steam enters vapour system, condensate water is got back to boiler, has realized the utilization of steam resource circulation, significantly energy savings.This system is reasonable in design, compact conformation, organic efficiency height, has very high economic worth.
