In the process of transporting ammonia, many pipelines are used, so that although the pressure and temperature at the input end of the pipeline are very high, when entering the engine, the pressure value and temperature are lost. Therefore, it is necessary to design a constant temperature and pressure stabilizing system to assist the transportation of ammonia. Summary of the invention

[0003] The purpose of this application is mainly to address the shortcomings of the prior art. A constant temperature and pressure stabilizing system is designed by setting a constant temperature tank in combination with a pressure stabilizing tank, which can compensate for the pressure and temperature lost during the ammonia transportation process, thereby ensuring that the pressure and temperature of the ammonia entering the engine meet the preset requirements. This solves the problem that in the current ammonia transportation process, due to the use of many pipelines, although the pressure and temperature at the input end of the pipeline are very high, the pressure and temperature are not enough when entering the engine.

The heated gas input ends of two of the three pressure-stabilizing tanks are each provided with a pressure relief valve, the input ends of the pressure relief valve are connected to the constant temperature tank, and the output ends of the pressure relief valve are connected to the pressure-stabilizing tank. The heated gas output ends of the pressure-stabilizing tanks that are not provided with pressure relief valves among the three pressure-stabilizing tanks are each provided with a first flow solenoid valve, and the heated gas output ends of the other two pressure-stabilizing tanks are each provided with a second flow solenoid valve.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] 1. The present application adopts the method of setting a constant temperature tank in combination with a pressure stabilizing tank to design a constant temperature and pressure stabilizing system, which can compensate for the pressure and temperature lost during the ammonia transportation process, thereby ensuring that the pressure and temperature of the ammonia entering the engine meet the preset requirements, and solves the problem that in the current ammonia transportation process, due to the use of many pipelines, although the pressure and temperature at the input end of the pipeline are very high, when entering the engine, the pressure value and temperature are not enough.

[0014] 2. In the present application, three pressure-stabilizing tanks are provided, one of which is the main pressure-stabilizing tank, and the other two are auxiliary.

[0015] 3. The setting of the pressure relief valve in the present application ensures that when the pressure value in the main pressure-stabilizing tank exceeds the limit, a part of the ammonia gas is transported to the other two pressure-stabilizing tanks through the pressure relief valve, thereby ensuring that the pressure value in the main pressure-stabilizing tank reaches the preset requirement, and the other two pressure-stabilizing tanks store the ammonia gas discharged by the pressure relief valve; when the pressure value of the ammonia gas output by the main pressure-stabilizing tank is insufficient, the control system adjusts the opening and closing size of the second flow solenoid valve according to the information fed back by the first flow solenoid valve, thereby releasing ammonia gas from the two non-main pressure-stabilizing tanks to assist the main pressure-stabilizing tank, thereby ensuring that the pressure value of the ammonia gas entering the engine reaches the preset requirement.

[0020] like Figure 1-3 As shown, a constant temperature and pressure stabilizing system comprises a constant temperature tank 1, a pressure stabilizing tank 2, and a bracket 3. The constant temperature tank 1 and the pressure stabilizing tank 2 are both fixed on the bracket 3. The constant temperature tank 1 has a heating liquid cavity 4 and a heated gas containing cavity 5. The heated gas containing cavity 5 is located in the heating liquid cavity 4. The heated gas output end of the constant temperature tank 1 is connected to the heated gas input end of the pressure stabilizing tank 2. The constant temperature tank 1 is provided with a liquid inlet pipe 6 and a liquid outlet pipe 7 connected to the heating liquid cavity 4.

[0021] Two thermostatic tanks 1 are arranged on the bracket, one of which is provided with a liquid inlet pipe 6 connected to the heating liquid chamber 4, and the other thermostatic tank 1 is provided with a liquid outlet pipe 7 connected to the heating liquid chamber 4. The heating liquid chambers 4 of the two thermostatic tanks 1 are connected through a pipeline, and the heated gas containing chambers 5 of the two thermostatic tanks 1 are connected to the interior of the pressure-stabilizing tank 2 through a heated gas output end. After such arrangement, the ammonia gas is heated by the two thermostatic tanks 1, so that the heating is faster;

[0022] The bracket is provided with three pressure stabilizing tanks 2, and the heated gas input ends of the three pressure stabilizing tanks 2 are connected to the heated gas output end of the thermostatic tank 1 through a five-way pipe 8. In this way, three pressure stabilizing tanks 2 are provided, one of which is the main pressure stabilizing tank 2, and the other two are auxiliary. When the pressure of the main pressure stabilizing tank 2 is insufficient, the other two auxiliary pressure stabilizing tanks 2 release ammonia together, thereby always ensuring that the pressure value of the ammonia entering the engine can meet the requirements;

[0023] It also includes a control system, a pressure relief valve 9, a first flow solenoid valve 10, and a second flow solenoid valve 11. The heated gas input ends of two of the three pressure-stabilizing tanks 2 are each provided with a pressure relief valve 9, the input ends of the pressure relief valve 9 are connected to the constant temperature tank 1, and the output ends of the pressure relief valve 9 are connected to the pressure-stabilizing tank 2. The heated gas output ends of the pressure-stabilizing tanks 2 that are not provided with pressure relief valves 9 among the three pressure-stabilizing tanks 2 are each provided with a first flow solenoid valve 10, and the heated gas output ends of the other two pressure-stabilizing tanks 2 are each provided with a second flow solenoid valve 11. The input end signal of the control system is connected to the first flow solenoid valve 10, and the output end signal of the control system is connected to the second flow solenoid valve 11 and the first flow solenoid valve 10. The fluid output end of the first flow solenoid valve 10 and the fluid output end of the second flow solenoid valve 11 are commonly connected to an output pipe 12. After such setting, the setting of the pressure relief valve 9 makes it possible that when the pressure value in the main pressure-regulating tank 2 exceeds, a part of the ammonia gas is transported to the other two pressure-regulating tanks 2 through the pressure relief valve 9, thereby ensuring that the pressure value in the main pressure-regulating tank 2 reaches the preset requirement, and the other two pressure-regulating tanks 2 store the ammonia gas discharged by the pressure relief valve 9; when the pressure value of the ammonia gas output by the main pressure-regulating tank 2 is insufficient, the control system adjusts the opening and closing size of the second flow solenoid valve 11 according to the information fed back by the first flow solenoid valve 10, thereby releasing ammonia gas from the two non-main pressure-regulating tanks 2 to assist the main pressure-regulating tank 2, thereby ensuring that the pressure value of the ammonia gas entering the engine reaches the preset requirement.

[0024] In this embodiment, the heating liquid enters the heating liquid chamber 4 from the liquid inlet pipe 6, and then flows out from the liquid outlet pipe 7. The heated gas containing chamber 5 located in the heating liquid chamber 4 is used to contain ammonia. After the ammonia enters the heated gas containing chamber 5, it exchanges heat with the heating liquid in the heated liquid chamber 4, so that the ammonia has a preset temperature value, and then is transported from the heated gas output end of the pressure regulating tank 2 to the engine. The whole process can ensure the temperature of the ammonia and the pressure of the ammonia entering the engine.

[0025] As a preferred mode, a heat insulation screen is provided in the side wall of the thermostatic tank 1. In this way, the heat in the thermostatic tank 1 is prevented from being lost in the air by the provision of the heat insulation screen.

[0026] As a preferred embodiment, a pressure gauge 13 is provided on the output pipe 12, and a signal of the pressure gauge 13 is connected to the control system. The pressure gauge 13 is provided to feed back the pressure value of the ammonia gas entering the engine to the control system.

[0027] As a preferred mode, a thermometer 14 is provided in the heating liquid cavity 4, and the signal of the thermometer 14 is connected to the control system. By setting the thermometer 14, the temperature in the heating liquid cavity 4 can be detected, so as to facilitate adjustment according to actual conditions.
