Description of drawings
The structural representation of the superheated water voltage-stabilizing system that is used for continuous annealing furnace that Fig. 1 provides for the utility model embodiment.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples, and certain following embodiment should not be construed as restriction of the present utility model.
As shown in Figure 1, a kind of superheated water voltage-stabilizing system for continuous annealing furnace that it provides for the utility model embodiment, the water that it comprises topping-up pump 14, be used for to give storage tank 16 that topping-up pump 14 supplies water, be used for regulating storage tank 16 liquid levels is regulated injection tube 15, pressure controller 19, energy storage 13, is reached cooling tank 9.Energy storage 13 links to each other with cooling tank 9 respectively with topping-up pump 14.Cooling tank 9 is communicated with superheated water major cycle pipeline 2, in the present embodiment, links to each other by pipeline 6 between cooling tank 9 and the superheated water major cycle pipeline 2.Pressure controller 19 is for detection of the pressure of superheated water major cycle pipeline 2, and force value and the normal value of described detection compared, when the unlatching of the difference of detecting pressure value and normal value control topping-up pump 14 during greater than preset value.Be provided with trip valve 8 between cooling tank 9 and the pipeline 6.Energy storage 13 ingress are provided with trip valve 12.Cooling tank 9 ingress are provided with valve 11.Valve 11 and trip valve 12 are used for cutting off respectively energy storage 13 and cooling tank 9.The top of pipeline 6 is provided with Safety relief valve 7, is used for when the pipe network hypertonia, and safety is diffused.The ingress of storage tank 16 is provided with trip valve 17.Water is regulated injection tube 15 and is provided with adjusting water injection self-acting valve 18.
This superheated water voltage-stabilizing system also comprises the water pipe 3 that is connected with superheated water major cycle pipeline 2.Be disposed with manual valve 5 and check valve 4 on the water pipe 3.Water pipe 3, manual valve 5, and check valve 4 be used for being full of water for for the first time closed circuit superheated water circulation line or replenishing after maintenance and a large amount of the leakage.In the present embodiment, energy storage 13 is gas-loaded formula energy storage.
The working process of this superheated water voltage-stabilizing system is as follows:
Reclaim the superheated water that flue gas/superheated water interchanger 10 produces of fume afterheat, be fed to user's points such as unit cleaning section through recycle pump 1, after heat is supplied with the user, the superheated water of low temperature is got back to interchanger again by pipeline 2 and is heated again, superheated water is closed cycle in pipe network, users such as constantly absorption fume afterheat, and supply cleaning section put heat; When the unit change of production, the exhaust gas volumn of generation is in fluctuation;
Served as superheated water temperature that hot water heat exchanger 10 produces because of flue gas heat when very sufficient, the temperature of superheated water can raise fast, causes that the pipe internal pressure improves, at this moment, safety pressure margin in the superheated water major cycle pipeline 2 can pass through pipeline 6, and through being delivered to storage in the energy storage 13 behind the cooling tank 9.Because energy storage 13 is by the rubber film equilibrium pressure in the jar, for protection energy storage 13 and respective line, before energy storage 13, set up cooling tank 9, superheated water enters energy storage 13 again after cooling tank 9 coolings;
When the pressure in the superheated water major cycle pipeline 2 has little pressure drop, can be by the safety pressure margin self-equilibrating of storage in the energy storage 13.When the difference of the force value of pressure controller 19 detected superheated water major cycle pipelines 2 and normal value during greater than preset value, show that then the pressure energy that discharges in the energy storage 13 is not enough, can't pass through energy storage 13 self-equilibratings, therefore control the unlatching of topping-up pump 14, be used for to 2 pressurizations of superheated water major cycle pipeline.Water in the topping-up pump 14 derives from storage tank 16.Liquidometer is set in storage tank 16 and valve 18 has linkage relationship, liquid level is crossed when low in detecting storage tank 16, and valve 18 is opened automatically, the soft water of annotating in the storage tank 16.Valve 17 is used for closing of storage tank 16.
