Abstract

The utility model relates to a boiler waste steam directional discharging and recovering device for a power station, which is a special device for reclaiming a great amount of dispersed steam and the waste steam, wherein the dispersed steam is generated when the boiler in the power station discharges pollution and drains for expanding production; the waste steam is generated by equipment using the steam in other industries. The utility model is composed of an evaporation chamber, a drying chamber and an injection device, wherein one path of high temperature and pressure steam-water mixture which is exhausted by the boiler enters a surface type heat exchanger of the drying chamber, and the other path of the mixture enters the injection device; the steam in the evaporation chamber is sucked and pumped into the drying chamber by the injection device so as to exchange the heat; in such a way, the steam becomes the saturated steam under the setting pressure. The utility model has the advantages of novel structure, less heat pollution, no noise, energy saving, etc., and is a new, economic and practical boiler waste steam directional discharging and recovering device for the power station.

Description

Station boiler is arranged the waste steam retracting device surely

Technical field

Station boiler described in the utility model is arranged the waste steam retracting device surely, is a kind of be used for a large amount of waste steams of station boiler blowdown and dewatering capacity-enlarging generation or exhaust steam that other industry gas utilization unit produces, and recycles the special equipment that utilizes again.

Background technology

Station boiler is because want periodical blowdown, and the steam water interface that salt content is exceeded standard emits in a large number.Also has the exhaust steam of the gas utilization unit of other industry.Owing to do not have good recovery method, or do not have enough low-temperature receivers with its recovery of condensing, have to ground-to-airly in vain bleed off, cause a large amount of thermal waste.Simultaneously also surrounding environment is caused thermal pollution.Especially in winter, water smoke condenses on road and the building, brings many inconvenience for people's life.Even if adopt condensation to reclaim, can only obtain hot water, make steam become the low-quality heat.The energy can not make full use of.At existing problem, a kind of waste steam retracting device of research and design in the prior art, existing problem is very necessary in the prior art thereby overcome.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of waste steam retracting device of research and design.Be mainly used in the recycling of station boiler blowdown or other industry gas utilization unit exhaust steam, the drying of drying, become the saturated initial steam under the setting pressure.Improve the grade of steam, made it to become the higher initial steam of value.Reach the purpose of energy-saving and water-saving, minimizing thermal pollution.The utility model is made up of vaporization chamber, hothouse, induction apparatus.Be equipped with from bottom to top in the vaporization chamber face formula heat exchanger is housed in decompressor, filler, atomizing disk, the hothouse.Induction apparatus is loaded in the middle of vaporization chamber and the hothouse.Vaporization chamber described in the utility model and hothouse can make hothouse last, vaporization chamber under integral type, also can make independently split typely separately, connect by induction apparatus.Operation principle of the present utility model is: the HTHP steam water interface that boiler blow-off or other gas utilization unit are discharged, be divided into two-way, and one the road inserts induction apparatus, a road inserts in the hothouse.Set the operating pressure in the hothouse as required.The operating pressure signal is returned two automatic regulating valves of feeding, be used for controlling to adjust and enter the induction apparatus steam water interface and enter the ratio of hothouse inner face formula heat exchanger steam water interface and enter induction apparatus as power source with steam water interface, gas in the suction vaporization chamber, condensate water in the vaporization chamber is evaporated in a large number, and be inhaled into hothouse.This moist steam that partly may carry water droplet by the heat exchange drying of efficient reinforcement face formula heat exchanger, becomes the saturated initial steam under the setting pressure in hothouse.The steam water interface that enters hothouse inner face formula heat exchanger is cooled off by cooling because of exchange heat, is sent to decompressor decompression, dilatation in the vaporization chamber then, produces steam and is inhaled in the hothouse.In the vaporization chamber required a small amount of low-temperature receiver control and hothouse between pressure differential.Low-temperature receiver is provided by hydrophobic or other demineralized water.The utility model provides a kind of brand-new Steam Recovery mode will replace traditional blowdown system, because the whole recovery system is airtight operation, does not produce thermal pollution.Have advantages such as novel structure, protection environment, energy-saving and water-saving, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

Description of drawings

The utility model has two accompanying drawings, and wherein accompanying drawing 1; Station boiler is arranged waste steam retracting device integrative-structure schematic diagram accompanying drawing 2 surely: station boiler is arranged among the waste steam retracting device split structural representation figure surely: 1, automatic blowdown valve 2, decompressor 3, filler 4, atomizing disk 5, vaporization chamber 6, induction apparatus 7, backwater control valve 8, automatic regulating valve () 9, face formula heat exchanger 10, hothouse 11, check-valves 12, the female pipe 13 of boiler blow-off, automatic regulating valve (two) 14, hydrophobic female pipe

The specific embodiment

The new specific embodiment of this practicality as shown in drawings.Vaporization chamber 5 and hothouse 10 can be made integral type up and down, also can make split type.Induction apparatus 6 is loaded between two Room.Decompressor 2, filler 3, atomizing disk 4 are equipped with in vaporization chamber 5 inside.Face formula heat exchanger 9 is housed in the hothouse 10.Initial steam after pressurized dry the processing is sent into the user from the top of hothouse 10 through check-valves 11.Station boiler is arranged waste steam surely and is delivered to automatic regulating valve 8 and automatic regulating valve 13 respectively by the female pipe 12 of boiler blow-off.The throttle flow of automatic regulating valve 8 control and regulation induction apparatus 6.The throttle flow of the face formula heat exchanger 9 in the automatic regulating valve 13 control and regulation hothouses outer 10.Be provided with automatic blowdown valve 1 below the vaporization chamber 5, in time discharge the sewage in the vaporization chamber 5.Backwater control valve 7 is that the water that will hothouse can not evaporate in 10 are discharged to smoothly in the vaporization chamber and are discharged by automatic blowdown valve.Hydrophobic female pipe 14 is that hydrophobic or other demineralized water are sent into decompressor 2, the steam water interface after being depressurized with cooling.Cause the pressure differential between vaporization chamber 5 and the hothouse outer 10.

The utility model provides a kind of brand-new vapour-recovery unit, will replace traditional blowdown system, because the whole recovery system is airtight operation, so can not produce pollution.Atomizing disk and other perishable employing stainless steel material, prolong service life.The utility model except that automatic regulating valve slightly the electricity consumption, all the other do not need any power, and can reclaim a large amount of steam and hot water, are a kind of novel environmental protection and energy saving products.
