Abstract
The utility model discloses a vapor-recovery unit which is characterized by comprising a water mist heat absorber and a softened water tank. A vapor through hole is formed in the top of the water mist heat absorber, and a water mist spraying pipe and a hole-shaped heat absorbing plate are arranged below the vapor through hole. A vapor lead-in pipe is arranged below the hole-shaped heat absorbing plate, a return water pipe is arranged at the bottom of the water mist heat absorber, the return water pipe is communicated with the softened water tank, and water in the softened water tank is led into the water mist spraying pipe and is used in a circulating mode. The vapor-recovery unit carries out recovery of heat and condensed softened water through pollution discharge of a steam pocket and vapor discharge of a deaerator to achieve energy conservation and emission reduction, reduces heat consumption and environmental pollution, improves energy conservation performance of an evaporated cooling system and ensures stable running of the evaporated cooling system.
Description
Technical field
The utility model relates to a kind of vapour-recovery unit, is specifically related to a kind of novel vaporization cooling blowdown indirect steam retracting device.
Background technology
The indirect steam that vaporization cooling drum continuous blowdown, oxygen-eliminating device produce directly is discharged in the atmosphere, and exhaust temperature is respectively 180 ℃ and 104 ℃, directly slatterns heat, and environment is polluted.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of vapour-recovery unit, and drum blowdown, deaerator exhaust are carried out heat and the soft water that condenses recovery, reaches energy savings, reduces thermal loss and environmental pollution, meets enterprise's emissions requirements.
The technical solution adopted in the utility model is: a kind of vapour-recovery unit, it is characterized in that: comprise water smoke heat dump and softened water tank, water smoke heat dump top is provided with logical steam vent, logical steam vent below is provided with water smoke shower and poroid absorber plate, poroid absorber plate has the steam access tube, water smoke heat dump bottom is provided with return pipe, and return pipe is communicated with softened water tank, and the water of softened water tank leads to the water smoke shower and recycles.
In the such scheme, described logical steam vent below is provided with 1 ~ 4 group of water smoke shower and poroid absorber plate successively.
The enforcement principle of such scheme is: the indirect steam processing back that a utilizes platoon to produce substitutes the former system's steam that enters oxygen-eliminating device, absorbs heat, reclaims soft water, reduces consumption; Second step of b is with the heat, the water vapour that do not absorb fully in this medium (the platoon steam after oxygen-eliminating device utilizes), sending into the water smoke heat dump reclaims fully: the indirect steam that the indirect steam that vaporization cooling drum continuous blowdown produces is used for producing with oxygen-eliminating device after the soft water deoxygenation enters the water smoke heat dump, the water smoke heat dump is atmospheric unit, through spraying soft water absorbing and cooling temperature again, reclaim the indirect steam heat; Indirect steam behind steam access tube access to plant by the uniform heat absorption of poroid absorber plate, through mixing the formation heat exchange with the soft water water smoke that the water smoke shower generates of flowing through, steam is condensed into little water droplet, cool off poroid absorber plate, water smoke cools off absorber plate simultaneously, reclaims indirect steam; Utilize the heat soft water preheating of medium and the water with fixed attention of recovering medium, thoroughly realize the recovery of vaporization cooling blowdown indirect steam.
The vapour-recovery unit that the utility model provides relates to hot continuous rolling production line heating furnace vaporization cooling drum blowdown and oxygen-eliminating device and discharges, and the indirect steam that is used for the blowdown of vaporization cooling drum, oxygen-eliminating device discharging generation reclaims.By this indirect steam retracting device, the indirect steam that drum blowdown, deaerator exhaust are produced reclaims conversion, is used for the heating of evaporated cooling system soft water, deoxygenation, realizes energy-saving and emission-reduction and environmental protection, improves the energy-conservation and stable of evaporated cooling system.The application of this device is estimated to save about 66.8 ten thousand yuan/year, and indirect steam can improve the soft water water temperature about 11.5 ℃ simultaneously, improves deaerating effect:
The indirect steam that the drum continuous blowdown produces is about 0.85t/h, the steam that the oxygen-eliminating device secondary produces is about 0.048 t/h, annual 8400 hours working times, 4 heating furnaces, save steam 30172.8 t/, steam per ton is equivalent to 2.768GJ, 1GJ=8 unit, (0.85t/h+0.048 t/h) * 8400 hour/year * 2.768GJ/t * 8 yuan/GJ=668146.4832 unit/year.
Below in conjunction with drawings and Examples the utility model is described further.

1 is drum among the figure, and 2 is the platoon flash vessel, and 3 is oxygen-eliminating device, and 4 is the water smoke heat dump, and 5 is softened water tank, and 6 are logical steam vent, and 7 is the water smoke shower, and 8 is poroid absorber plate, and 9 is the steam access tube, and 10 is return pipe, and 11 is circulating water pipe.
The specific embodiment
Embodiment:
In conjunction with Fig. 1,2, the principle of the vapour-recovery unit that elaboration the utility model provides is as follows:
The indirect steam that the indirect steam that cooling drum 1 continuous blowdown of vaporizing produces is used for producing with oxygen-eliminating device 3 after the soft water deoxygenation enters water smoke heat dump 4, and water smoke heat dump 4 is atmospheric unit, through spraying soft water absorbing and cooling temperature again, reclaims the indirect steam heat; Indirect steam after steam access tube 9 enters water smoke heat dump 4 by poroid absorber plate 8 uniform heat absorptions, through mixing the formation heat exchange with the soft water water smoke that water smoke shower 7 generates of flowing through, steam is condensed into little water droplet, cool off poroid absorber plate 8, water smoke cools off absorber plate simultaneously, reclaims indirect steam.
Vapour-recovery unit, comprise water smoke heat dump 4 and softened water tank 5, the structure of water smoke heat dump 4 is: water smoke heat dump 4 tops are provided with logical steam vent 6, logical steam vent 6 belows are provided with water smoke shower 7 and poroid absorber plate 8, poroid absorber plate 8 has steam access tube 9, the bottom of water smoke heat dump 4 is provided with return pipe 10, and return pipe 10 is communicated with softened water tank 5, and the water of softened water tank 5 leads to the water smoke shower through circulating water pipe 11 and recycles.
Water smoke heat dump shown in Fig. 2 comprises two groups of water smoke showers and poroid absorber plate, and on-site verification arranges two groups of water smoke showers and poroid absorber plate best results.
Respond well behind the Taiyuan Iron and Steel Co. hot continuous rolling 2250mm of factory production line 1# heating furnace vaporization cooling this novel vaporization cooling blowdown secondary steam recovery system on probation, 2-4# heating furnace vaporization cooling is utilizing the heating furnace furnace outage time to try out installation successively.
