The utility model is achieved in that the heating agent storage tank comprises tank body, level meter, liquid distributor, manhole, manhole ladder, outer ladder and ventilating hole.The vertical cylindrical tank of tank body steel plate welding has ventilating hole on tank deck, the bottom has manhole ladder and outer ladder on the manhole tank skin, and tank base is fixed with sewage draining exit.It is characterized in that: in the bottom of tank body the heating agent import is arranged, the heating agent import is connected with liquid distributor, and the top of liquid distributor is fixed with liquid distribution plate, makes the heating agent current stabilization that enters.Roof anchorage at tank body has the liquid of receipts dish, receives the liquid dish and is communicated with the heating agent conduit.The heating agent outlet of heating agent conduit is fixed on tank base.The even distribution is fixed with the thermometer mouth on tank skin from the tank body top to tank base, and the thermometer mouth can insert thermometer, and layering detects the heat medium temperature in the tank body.
Described liquid distribution plate is made up of steel plate, is evenly distributed with aperture on the steel plate, and the diameter of aperture is between the 5-7 millimeter, and every square decimeter has 0.5 aperture.Steel plate is welded in the tank body.The structure of liquid distributor has an airtight cylinder in the middle of being, the radial welding on every side of cylinder also is communicated with steel pipe, is evenly distributed with aperture on the steel pipe.There is steel pipe to be communicated with between airtight cylinder and the heating agent import.
Described receipts liquid dish is a disc, and the upper edge of receiving the liquid dish is a zigzag fashion, and the bottom of receiving the liquid dish is communicated with the heating agent conduit.
The working principle of summary heating agent storage tank helps to understand the utility model.Be full of heating agent in tank body, the high temperature heating agent is on the top of tank body; The low temperature heating agent is in the bottom of tank body.The high temperature heating agent is received the liquid dish on the top of tank body and is collected equably, and is transported to the heating agent outlet by the heating agent conduit, offers vaporising device and LNG and carries out heat exchange.Low temperature heating agent after the heat exchange cooling is heated the back and is entered by the heating agent tank bottom and behind bottom liquid distributor, the even cloth liquid of liquid distribution plate, enter the heating agent storage tank.High temperature heating agent and low temperature heating agent store in same heating agent storage tank, and the temperature of high temperature heating agent is greatly between the 90-95 degree; Between the 65-70 degree, the temperature difference of high temperature heating agent and low temperature heating agent is between the 20-25 degree greatly for the temperature of low temperature heating agent.
The beneficial effects of the utility model: the heating agent of different temperatures can be stored in the storage tank.This equipment of the utility model has reduced number of devices, invests to be 50% of old process, and operating cost saves about 50%.Be applied to the storage of the special-purpose heating agent in LNG Liquefied natural gas (LNG) vaporization station, take up an area of, reduce the operation and maintenance expense, improve peak regulation, played very big influence with LNG vaporization station its construction level to reducing investment, saving.Cooperate also energy of technology controlling and process by heating agent tank inside architecture advances.
