In this embodiment, the cabinet body is connected with the bottom side beam, and the cabinet body is fixed, so that the heater 35 is more convenient to overhaul and maintain by the arrangement mode.
In this embodiment, the cabinet, the circulating pump 31 and the heater 35 are located on the same side of the tank body 2 and are sequentially arranged along the direction from the front end frame to the rear end frame, that is, the heater 35 is close to the rear end frame, the circulating pump 31 is located in the middle of the bottom side beam, and the cabinet is located between the front end frame and the circulating pump 31.
In other embodiments, the cabinet may also be disposed at the rear end frame.
The control unit is electrically connected with the heater 35, the liquid ammonia temperature detector 5 and the heat carrier liquid temperature detector 6 respectively.
The control unit receives the real-time temperature of the liquid ammonia temperature detector 5 and the real-time temperature of the heat-carrying liquid temperature detector 6, and controls the heater 35 to heat when the real-time temperatures of the liquid ammonia and the heat-carrying liquid are lower than the preset temperature values.
The temperature preset value is calculated by the corresponding relation between the pressure of saturated ammonia gas and the temperature, wherein the pressure of the saturated ammonia gas comes from the requirement of a customer.
The liquid ammonia temperature detector 5 detects the real-time temperature of liquid ammonia in the tank body 2, the heat-carrying liquid temperature detector 6 detects the real-time temperature of the hot liquid carried on the circulating pipeline, and the heater 35 starts to heat only when the temperatures of the liquid ammonia and the heat-carrying liquid are lower than a preset temperature value, so that the accuracy is improved, and the safety is guaranteed. The condition that the unloading flow of the gaseous ammonia is higher than the requirement of a customer because the heater 35 starts heating when one of the liquid ammonia or the heat carrier liquid is lower than the preset temperature value is avoided.
For example, when the temperature of the heat carrying liquid is lower than the preset temperature value, but the temperature value of the liquid ammonia is higher than or equal to the preset temperature value, the liquid ammonia is enough to be converted into gaseous ammonia, if the heater 35 starts to heat, the temperature of the heat carrying liquid will rise, and the temperature of the liquid ammonia will rise, so that the unloading flow of the gaseous ammonia is larger than the customer demand. Or the temperature of the liquid ammonia is lower than the preset temperature value, but the temperature value of the heat carrying liquid is higher than the preset temperature value, at this time, heat exchange can be further performed between the liquid ammonia and the heat carrying liquid, so that the temperature of the liquid ammonia meets the requirement, if the heater 35 heats at this time, the temperature of the liquid ammonia is finally too high, and the unloading flow of the gaseous ammonia is larger than the requirement of a customer.

The temperature limiting device 36 is used for detecting the temperature in the heater 35, when the temperature in the heater 35 reaches the threshold value of the temperature limiting device 36, the temperature limiting device 36 sends the signal to the control unit, and the control unit controls the heater 35 to stop heating according to the signal. When the circulation pump 31 stops working due to a fault, the heater 35 continuously heats when the temperatures detected by the liquid ammonia temperature detector 5 and the heat-carrying liquid temperature detector 6 are lower than the preset temperature value, so that the temperature in the heater 35 is too high, and even the heat-carrying liquid is vaporized to cause the pressure in the circulation pipeline to be too high.
In particular, the temperature limiting device 36 is a temperature probe.
Further, the liquid ammonia tank container also comprises a pressure limiting device. The pressure limiting device is communicated with the interior of the tank body 2 and is used for detecting the real-time pressure in the tank body 2. The pressure limiting device is electrically connected with the control unit, when the pressure limiting device detects that the pressure in the tank body 2 reaches the threshold value of the pressure limiting device, the pressure limiting device sends the signal to the control unit, and the control unit controls the heater 35 to stop heating according to the signal, so that the temperature of the heat carrying liquid does not continuously rise, the liquid ammonia is reduced to be converted into gaseous ammonia, the pressure in the tank body 2 is prevented from continuously increasing, and the safety of the tank body 2 is ensured.
In particular, the threshold value of the pressure limiting device is smaller than the design pressure value of the tank 2. For example, 0.9 times the design pressure value of the tank 2, 0.8 times the design pressure value of the tank 2, etc.
The flow detector is arranged on the gas phase pipeline 4 of the tank body 2 and is used for detecting the flow of the gaseous ammonia output from the gas phase pipeline 4. The flow detector is electrically connected to the control unit and sends the flow of gaseous ammonia to the control unit. The control unit calculates the heating power of the heater 35 according to the difference between the flow rate and the preset flow rate value, and controls the heater 35 to heat with the heating power, so that the final flow rate of the gaseous ammonia in the gas phase pipeline 4 is the same as the preset flow rate, unloading is more accurate, and customer requirements are better met.
The control unit controls the heater 35 to heat through the solid-state relay. In this embodiment, the solid state relay is a thyristor solid state relay.
Specifically, the rated power of the heater 35 is 1.3 times the power required for the maximum unloading flow of the tank 2.
In other embodiments, the flow detector may also be a pressure detector. The heating power of the heater 35 is calculated according to the difference between the detected pressure and the preset pressure.
In another embodiment, the gas phase pipeline 4 may be provided with a flow detector and a pressure detector. The two can be backed up by each other, i.e. the control unit calculates the heating power of the heater 35 according to one of them. The two can also work simultaneously, namely the control unit finally calculates to obtain heating power according to the detection values of the two.
The GPS unit is used for detecting the position of the liquid ammonia tank container in real time in the transportation process of the liquid ammonia tank container, the position information is uploaded to the cloud database, and a user can check the position of the liquid ammonia tank container through the cloud database.
The monitoring unit is used for monitoring the running state information of the liquid ammonia tank container, such as the pressure and the temperature in the tank body 2, the temperature of the heating evaporation system 3 and the like.
The liquid ammonia tank container can be used for transporting liquid ammonia, can be positioned by the GPS unit when in use, and can also monitor the state of the liquid ammonia tank container by the monitoring unit; after the liquid ammonia is transported to the destination, the liquid ammonia is unloaded, and the gaseous ammonia is directly output through the liquid ammonia tank container for users to use.
