Background technology
It is well known that the katathermal solution circulatory system of large capacity is typically employed in liquid accumulation of heat heating system.It is different from
Common hydrothermal circulation system, the regenerator temperature of the katathermal solution circulatory system of large capacity are more than 100 degree, and operating temperature generally exists
110-150 degree, operating pressure is in 0.2-0.7MPa.Due to being equipped with the accumulation of heat flow container of large capacity, hydrothermal circulation system liquid in system
Capacity is generally in 500-2000m3, so that the expansion liquid measure of Hydrothermal System is very big, expansion liquid measure is up to 20-100m3.Due to bellows
Enclosed level pressure expansion drum smaller, and the non-refractory that can accommodate expansion liquid measure, be not suitable for the high-temperature bearing hydrothermal solution of large capacity
System.Now mostly using open type liquid case as expansion gear, but when largely high-temperature expansion liquid drains into hydrothermal circulation system
During open type liquid case, indirect steam discharge can be produced, waste and security risk are caused, additionally, due to the hydrothermal solution and sky in open type liquid case
Gas contacts, and can corrode liquid case, when hydrothermal circulation system pressure reduces, is supplemented to the inflation fluid of air contact by fluid infusion pump

Temperature, state of matter keeps liquid during in order to unload.More commonly used usually has three kinds of methods, and one kind is added with steam
Heat, one kind are directly to use fired heater heating tank box body, and it is to install electrothermal tube, these types side additional around babinet to also have one kind
Method cuts both ways.There is steam generator at steam heating requirements scene, can only be used in fixed state, in the state of movement
Difficult to realize, and the dangerous property of high temperature steam operations, temperature is difficult to control during heating, be easy to cause overheat.Flame heats
Device is then because there is naked light, and there are fire hazard, temperature is not easily controlled, the problem of being equally difficult to avoid that excessive heating.Babinet week
Enclose and install electrothermal tube in insulating layer additional, can be very good control heating progress, but recondition expense is fairly expensive, electrothermal tube adds in addition
Heat is also there are a drawback, once failure at electrothermal tube, whole tank case must return to stockyard maintenance, can not be put into again in the short time
Use.
Expansion drum is provided in the device on circulating line, and main function has：1. liquid is due to heated in suction line system
And the expansion produced, prevent pipeline burst；2. steady pressure of system is realized toward tank deck nitrogen charging by nitrogen pressure regulating valve；3. pass through
The liquid level change of liquid level gauge on expansion drum realizes automatic liquid supply with the automatic liquid supply valve interaction of pump house.
