Furthermore, waste heat is made full use of, and energy is utilized fully and efficiently.
Description
Technical field
The utility model relates to a kind of using waste heat from tail gas and utilizes system, is specifically related to a kind of Steam Jet Vacuum Pump using waste heat from tail gas and utilizes system.
Background technique
Steam Jet Vacuum Pump is refining magnesium industry provides vacuum visual plant to reduction tank, and this pump can produce a large amount of tail gas in running, and directly outer being discharged in air of this part tail gas in production process (120 DEG C), has caused the waste of thermal source; And the water that participates in ejector vacuum pump circulation need to be processed to avoid the corrosion to pipeline, boiler etc. through softening, and the steam that softened water produces is at present all in line to air, has formed very large waste.
Given this, be necessary to design a kind of ejector vacuum pump vapor recovery system and solve the problems referred to above.
Model utility content
The technical problems to be solved in the utility model is: a kind of ejector vacuum pump vapor recovery system is provided, and it can effectively reclaim soft water and waste heat.
For achieving the above object, the utility model provides following technological scheme: a kind of ejector vacuum pump vapor recovery system, comprise soft water processing unit, there is the boiler of soft water entrance and vapor outlet port and there is vapour inlet and the Steam Jet Vacuum Pump system of tail gas outlet, described soft water entrance is communicated with soft water processing unit, described vapor outlet port and vapour inlet are connected, described tail gas outlet is also communicated with and is provided with heat exchange unit, described ejector vacuum pump vapor recovery system is also provided with the tank that reclaims the rear tail gas of liquefaction, described tank is directly or indirectly connected with the soft water entrance of boiler.
Further, described heat exchange unit comprises the loop being made up of heat exchanger, recycle pump and heating unit.
Further, described heat exchange unit also comprises the water-supplying mouth to the moisturizing of described loop.
Further, the liquid water that described tank collection ejector vacuum pump vapor recovery system produces midway and the condensed water of process heat exchange unit.
Further, described tank is connected with soft water processing unit.
Further, described tank is directly connected with the soft water entrance of boiler without soft water processing unit.
Compared with prior art, the utility model at least has the following advantages: the ejector vacuum pump vapor recovery system that described increase has heat exchange unit, not only soft water fully can be reclaimed, and save soft water processing cost, raise the efficiency; Also take full advantage of waste heat, realize the energy and fully and effectively utilize simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model ejector vacuum pump vapor recovery system.
Embodiment
Refer to Fig. 1, describe the embodiment of the utility model ejector vacuum pump vapor recovery system 100 below in conjunction with accompanying drawing in detail.
Described ejector vacuum pump vapor recovery system 100 comprises soft water processing unit 1, there is the boiler 2 of soft water entrance and vapor outlet port and there is vapour inlet and the Steam Jet Vacuum Pump system 3 of tail gas outlet, described soft water entrance is communicated with soft water processing unit 1, described vapor outlet port and vapour inlet are connected, the outlet of described tail gas be also communicated be provided with heat exchange unit 4(and be communicated with heat exchanger 6 by the tail gas outlet welded pipe line of Steam Jet Vacuum Pump system 3 and realize), described ejector vacuum pump vapor recovery system 100 is also provided with the tank 5 that reclaims the rear tail gas of liquefaction, described tank is directly connected with the soft water entrance of boiler 2 without soft water processing unit 1.Described heat exchange unit 3 comprises the loop being made up of heat exchanger 6, recycle pump 7 and heating unit 8.Described heat exchange unit 3 also comprises the water-supplying mouth 9 to the moisturizing of described loop.Described tank 5 is collected condensed water that ejector vacuum pump vapor recovery system 100 produces and the condensed water through heat exchange unit 4 midway.The ejector vacuum pump vapor recovery system that described increase has heat exchange unit, not only can fully reclaim soft water, saves soft water processing cost, raises the efficiency; Also take full advantage of waste heat, realize the energy and fully and effectively utilize simultaneously.
As shown in Figure 1, introduce the working procedure of ejector vacuum pump vapor recovery system 100 below.The soft water of processing through soft water processing unit 1 enters boiler 2, adds thermogenetic steam and enters Steam Jet Vacuum Pump system 3, makes tail gas pass through heat exchanger 3.The water of heat exchange unit 4 has formed a closed-loop path through heat exchanger 6 and heating unit 8, water in this loop carries out cycle heat exchange by the pressurization maintenance of recycle pump 7 and Steam Jet Vacuum Pump system 3 outer rows' tail gas (120 DEG C), and the heating water (75～80 DEG C) after heat exchange is plant area's heating.In the loop of this heating system, be provided with water-supplying mouth 9, guarantee having abundant water resources of heating system; And, carrying out after heat exchange with normal-temperature water, final tail gas becomes condensed water and together flows into tank 5 with the condensed water that Steam Jet Vacuum Pump system produces after cooling, and small part steam is arranged atmosphere outward.In the present embodiment, the water of condensation in tank 2 to soft water pond, can make again the exhaust heat boiler of rotary kiln reuse this part water source by row of conduits.
In sum, these are only preferred embodiment of the present utility model, should not limit scope of the present utility model with this.For example, in the present embodiment, described tank is connected with soft water processing unit, does not directly enter boiler; In some other embodiment, described tank also can directly be connected with the soft water entrance of boiler without soft water processing unit.Be described tank be directly or indirectly connected with the soft water entrance of boiler all can, this does not also affect the realization of technical solutions of the utility model.Be that every simple equivalence of doing according to the utility model claims and description changes and modifies, all should still belong in the scope that the utility model patent contains.
