Description
一、技术领域：本实用新型涉及一种低温液体装置，尤其是一种带防过量充装装置的液化天然气储罐。1. Technical field: The utility model relates to a cryogenic liquid device, especially a liquefied natural gas storage tank with an overfilling prevention device.
二、背景技术：国内外已有的低温液体储罐，即储存液氮、液氧、液氢、液氩和液化天然气等低温液体的储罐，其防过量充装措施一般有两种。一种方法是通过观察液位计的显示，当储罐液位计显示储罐液位已达到最大允许充装液位时，停止充装。这种方法存在的不足是当液位计失灵或操作工不能及时发现储罐液位已达最大允许充装液位时，容易使储罐液位充装过量。另一种措施为储罐设置溢流阀，该阀的抽出口设在储罐最大允许充装液位处。这种方法存在的不足是必须打开溢流阀才能判断储罐是否充装过量。2. Background technology: The existing cryogenic liquid storage tanks at home and abroad, that is, storage tanks for storing liquid nitrogen, liquid oxygen, liquid hydrogen, liquid argon, and liquefied natural gas, generally have two anti-overfilling measures. One method is to observe the display of the liquid level gauge, and stop filling when the tank level gauge shows that the liquid level of the storage tank has reached the maximum allowable filling level. The disadvantage of this method is that when the liquid level gauge fails or the operator cannot find in time that the liquid level of the storage tank has reached the maximum allowable filling level, it is easy to overfill the liquid level of the storage tank. Another measure is to set an overflow valve for the storage tank, and the outlet of the valve is set at the maximum allowable filling level of the storage tank. The disadvantage of this method is that the overflow valve must be opened to determine whether the storage tank is overfilled.
三、发明内容：本实用新型的目的在于克服现有技术存在的上述不足，提供一种带防过量充装装置的液化天然气储罐。本实用新型的目的是这样实现的，它是由外壳、内壳、绝热材料、防爆器、充装口、安全阀、放空阀、主腔室、辅腔室、小孔、抽出口连接而成，液化天然气储罐设置外壳和内壳，外壳和内壳之间有绝热材料；外壳上安装着防爆器；内壳设置为主腔室和辅腔室，且中间有隔层；主腔室上安装着充装口和抽出口，并在主腔室的气相管线上安装着安全阀和放空阀；辅腔室位于内壳的一端，容积为内壳总容积的5～10％，其顶端和底部分别有小孔与主腔室相通。3. Summary of the invention: The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and provide a liquefied natural gas storage tank with an overfilling prevention device. The purpose of this utility model is achieved in that it is formed by connecting the outer shell, inner shell, heat insulating material, explosion-proof device, filling port, safety valve, vent valve, main chamber, auxiliary chamber, small hole, and extraction port. , the liquefied natural gas storage tank is provided with an outer shell and an inner shell, and there is a heat insulating material between the outer shell and the inner shell; an explosion-proof device is installed on the outer shell; A filling port and a pumping port are installed, and a safety valve and a vent valve are installed on the gas phase pipeline of the main chamber; the auxiliary chamber is located at one end of the inner shell, and its volume is 5-10% of the total volume of the inner shell, and its top and Small holes are respectively arranged at the bottom to communicate with the main chamber.
液化天然气的充装通过液化天然气充装口实现。当充装液化天然气时，主腔室的液位升高很快，由于辅腔室与主腔室相连的小孔的孔径很小，辅腔室的液位升高非常缓慢。当主腔室的液位升高至顶部充装口位置时，由于充装阻力增大，充装流量迅速降低，此时有电信号传给泵电机，使泵停转，停止充装，从而防止了液化天然气储罐充装过量。此时辅腔室的液位依然很低，由于主腔室的液位已充满，主腔室内的液化天然气通过下面的小孔逐渐流到辅腔室，直到主腔室和辅腔室的液位一致。当使用液化天然气时，主腔室的液位降低，辅腔室的液位随之降低，由于液化天然气排出的速度较慢，辅腔室和主腔室的液位下降的速度基本相同，保证了储罐内液化天然气能够用完。The filling of liquefied natural gas is realized through the filling port of liquefied natural gas. When the liquefied natural gas is filled, the liquid level of the main chamber rises rapidly, but the liquid level of the auxiliary chamber rises very slowly because the aperture of the small hole connecting the auxiliary chamber with the main chamber is very small. When the liquid level in the main chamber rises to the position of the filling port at the top, the filling flow decreases rapidly due to the increase of filling resistance. At this time, an electric signal is sent to the pump motor to stop the pump and stop filling, thus preventing LNG storage tanks were overfilled. At this time, the liquid level in the auxiliary chamber is still very low. Since the liquid level in the main chamber is full, the liquefied natural gas in the main chamber gradually flows into the auxiliary chamber through the small hole below until the liquid in the main chamber and the auxiliary chamber bits match. When liquefied natural gas is used, the liquid level of the main chamber decreases, and the liquid level of the auxiliary chamber decreases accordingly. Since the discharge speed of liquefied natural gas is slow, the liquid level of the auxiliary chamber and the main chamber drop at basically the same speed, ensuring The liquefied natural gas in the storage tank can be used up.
此产品与国内外同类产品相比，具有防过量充装措施可靠、液化天然气储存安全等优点。Compared with similar products at home and abroad, this product has the advantages of reliable anti-overfilling measures and safe storage of liquefied natural gas.
