The utility model discloses a buffer kettle convenient to operate, which is shown in figures 1 to 3, and comprises a buffer kettle body 1, a heating coil pipe 2, a heat conducting pipe 21, a heat tracing pipe 3 and a heating tank 5. Wherein, the buffer kettle body 1 is internally provided with a cavity for inputting materials. The buffer kettle body 1 is externally provided with a plurality of groups of heating coils 2 from top to bottom, and each heating coil 2 is spirally wound outside the buffer kettle body 1, so that the buffer kettle body 1 is heated layer by layer in the height direction.
With continued reference to fig. 1, the heat pipe 21 has a U-shape, and the molten salt inlet 201 of each heating coil 2 is connected to one side of the heat pipe 21, and the molten salt outlet 202 of each heating coil 2 is connected to the other side of the heat pipe 21, so that the heat pipe 21 and each heating coil 2 are connected to form a closed pipeline. Liquid molten salt is introduced into a closed pipeline formed by the heat conducting pipe 21 and each heating coil pipe 2, meanwhile, a first pump body 22 is further arranged on one side of the heat conducting pipe 21, the liquid molten salt is pumped out through the first pump body 22, so that the liquid molten salt is conveyed to one end of each heating coil pipe 2 from one side of the heat conducting pipe 21, conveyed in the heating coil pipe 2, and then output to the other side of the heat conducting pipe 21 from the other end of the heating coil pipe 2, and a circulating flow process is formed.
The top of the buffer kettle body 1 is provided with a feed inlet 101 and an oil gas outlet 104, and the bottom of the buffer kettle body 1 is provided with a discharge outlet 102. Valves are arranged at the feeding hole 101, the discharging hole 102 and the oil gas outlet 104, and materials are input into the buffer kettle body 1 from the feeding hole 101. Preferably, the top in the buffer kettle body 1 is also fixed with a distributor 11, and the materials input into the buffer kettle body 1 fall down in a uniform distribution manner through the distributor 11. Meanwhile, after the materials in the buffer kettle body 1 are heated by the external heating coil pipe 2, the separation of light components (namely oil gas) and heavy components in the materials is accelerated, so that the light components can float upwards and be discharged from the oil gas outlet 104, and the heavy components can sink and be discharged from the discharge port 102.
Since the high temperature light components above the inside of the buffer kettle body 1 may contain a small amount of heavy components, the light components entrain heavy components to cause blockage of pipelines for outputting the light components and oil gas cooling equipment, and simultaneously, the recovery rate of the heavy components is reduced. Thus, as shown in fig. 6, preferably, a buffer tank 6 is also matched with the buffer kettle body 1, the oil gas outlet 104 of the buffer kettle body 1 is connected with the buffer tank 6 through a pipeline, and the pipeline is connected to the bottom of the buffer tank 6. The foam remover 61 is fixed above the buffer tank 6, and the foam remover 61 is a grid frame with a surface encapsulated metal net. In the process of the operation of the buffer kettle, the light component enters the buffer tank 6 upwards from the oil gas outlet 104, and when the light component rises in the buffer tank 6 at a certain speed and passes through the foam remover 61 arranged in the buffer tank 6, the liquid foam in the light component collides with the metal net and adheres to the surface of the foam remover 61 due to the rising inertia effect of the light component, so that the effect of removing a small amount of heavy components contained in the light component is achieved. And the liquid foam adhered on the surface of the filaments of the metal net is further diffused and the liquid foam is settled by gravity, so that the liquid foam forms larger liquid drops and flows to the interweaving positions of the filaments along the filaments. Meanwhile, as the filaments of the metal mesh have wettability, capillary action and surface tension of liquid, liquid drops at the interweaving position of the filaments of the metal mesh are larger and larger until the gravity of the liquid drops exceeds the resultant force of the rising buoyancy of gas and the surface tension of the liquid, the liquid drops are separated and fall down and flow back into the buffer kettle body 1, so that the aim of intercepting heavy components in light components by the foam remover 61 is fulfilled, and the yield of the heavy components can be increased.
In addition, since the space in the buffer tank body 1 is limited and the gas phase space of the buffer tank body 1 is increased after the buffer tank 6 is communicated with the buffer tank body, the buffer tank body has a function of stabilizing the pressure to a certain extent. The pressure fluctuation in the buffer kettle body 1 is relatively smaller, and the control is easier, so that the product quality is more stable. Further, a gas phase outlet above the buffer tank 6 is connected to a gas pipe 62, and the gas pipe 62 is connected to a regulating valve 63, and the pressure in the buffer tank 6 and the buffer tank body 1 can be regulated by the regulating valve 63.
As shown in fig. 3, the upper end of the buffer tank body 1 may further be fixed with a hanging ring 16 to hang the buffer tank body 1 on a frame. The top of the buffer kettle body 1 is further provided with an access hole 103, and a sealing cover is hinged to the access hole 103, so that workers can conveniently enter the buffer kettle body 1 when equipment needs to be overhauled.
As shown in fig. 5, one end of the circulation pipe 12 is connected to the upper end of the buffer tank body 1, the other end of the circulation pipe 12 is connected to the lower end of the buffer tank body 1, and the circulation pipe 12 is also connected to the third pump body 13. The third pump body 13 during operation is with the material of the inside lower extreme of buffer kettle body 1 through circulating pipe 12 extraction to in the buffer kettle body 1 upper end, makes the material in the buffer kettle body 1 form circulation from top to bottom to this prevents that the inside material of buffer kettle body 1 from not circulating and appear coking caking's phenomenon.
With continued reference to fig. 1, the high-temperature liquid is disposed in the heating tank 5, and the electric heating pipes 51 are distributed at the bottom outside the heating tank 5, and the electric heating pipes 51 can heat the heating tank 5 to maintain the high-temperature liquid in the heating tank 5 at a specified high temperature. The lower ends of the heat pipes 21 (i.e., bent portions connecting both sides) are located in the heating tank 5, and this structure allows the liquid molten salt to be heated in the heating tank 5 when flowing through the lower ends of the heat pipes 5, thereby maintaining the molten salt flowing back upward to each heating coil 2 in a high-temperature state, and thus heating the buffer tank body 1. In this heating method, the liquid molten salt is used as a heat transfer medium, so that the heating coil 21 has high heat conductivity compared with water, and the heat energy of the high-temperature liquid in the heating tank 5 can be quickly transferred to the buffer kettle body 1, thereby effectively increasing the heat energy and reducing the energy consumption.
The heat tracing pipes 3 are arranged on the heating coils 2, and the spiral arrangement of the heat tracing pipes 3 is arranged below the heating coils 2, namely, the spiral pitch of the spiral of the heat tracing pipes 3 is consistent with the spiral pitch of the spiral of the heating coils 2 as shown in fig. 4, so that the whole section of the heating coils 2 is contacted with the heat tracing pipes 3. Referring again to fig. 5, one end of each heat tracing pipe 3 is fixed to the liquid outlet pipe 32, and the other end of each heat tracing pipe 3 is connected to the liquid inlet pipe 31. The liquid inlet pipe 31 is also connected with a second pump body 33, and preferably, the second pump body 33, the first pump body 22 and the third pump body 13 can be liquid pumps. The lower end nozzle of the liquid outlet pipe 32 and the lower end nozzle of the liquid inlet pipe 31 are connected into the heating tank 5, and the upper end nozzle of the liquid outlet pipe 32 and the upper end nozzle of the liquid inlet pipe 31 are closed. In this configuration, the high-temperature liquid is fed from the liquid feed pipe 31 into each heat tracing pipe 3 through the second pump body 33, and the high-temperature liquid is returned from the liquid discharge pipe 32 into the heating tank 5, so that the heat tracing pipes 3 are brought to a high temperature, and the temperature is transferred to the heating coils 2, so that the solid molten salt in each heating coil 2 is heated to be liquefied, and the liquid molten salt can flow in a circulating manner.
Since the time period for which the heat pipe 21 feeds the liquid molten salt upward to each heating coil 2 is different, there is a possibility that the temperature at each position in the buffer tank body 1 is different. So the buffer kettle body 1 is provided with temperature measuring devices 4 under the heating coils 2, and temperature sensing probes of the temperature measuring devices 4 penetrate into the buffer kettle body 1, so that the temperature measuring devices 4 can sense the temperature condition of the buffer kettle body 1 at the positions of the heating coils 2. Furthermore, the utility model is also provided with a set of control system, the control system can be a PLC controller, the temperature measuring device is connected to the control system in a signal way, after the control system receives the signal of the temperature measuring device 4, the temperature information is fed back to a display screen (not shown in the drawing) for displaying, so that a worker can more intuitively observe the temperature condition of each heating coil 2, namely, the temperature condition of each position in the buffer kettle body 1. Further, the first pump body 22, the second pump body 33, the third pump body 13 and the electric heating tube 51 are all electrically connected to a control system, so that the control system can control the opening and closing of the first pump body 22, the second pump body 33, the third pump body 13 and the electric heating tube 51.
Preferably, as shown in fig. 2, the position of the buffer kettle body 1 near the top is further provided with a liquid level meter 14 and a pressure measuring meter 15, sensing probes of the liquid level meter 14 and the pressure measuring meter 15 extend into the buffer kettle body 1, and meanwhile, the liquid level meter 14 and the pressure measuring meter 15 are connected to a control system in a signal mode, so that after the control system receives signals of the liquid level meter 14 and the pressure measuring meter 15, temperature information is fed back to a display screen to be displayed. In this way, the material amount in the buffer kettle body 1 can be detected by the liquid level meter 14, and when the liquid level meter 14 detects the material, it is indicated that the material in the cavity of the buffer kettle body 1 is about to be filled, and the material inputting needs to be suspended. The pressure gauge 15 can be used for detecting the air pressure inside the buffer kettle body 1 in real time, so that workers can conveniently know the internal pressure of the buffer kettle body 1 in real time.
It is worth mentioning that the structure that the plurality of heating coils 2 are arranged outside the buffer kettle body 1 can enable the liquid molten salt to form a plurality of conveying pipelines to circulate outside the buffer kettle body 1 in a relatively dispersed manner, and the blocking probability can be reduced. In addition, the molten salt inlets 201 and the molten salt outlets 202 at the two ends of the heating coil 2 can be connected with the heat conducting pipe 21 through flange plates, so that the heating coil is convenient to detach. When the temperature of one temperature measuring device 4 does not reach the required high temperature, the heating coil 2 can be heated through the heat tracing pipe 3 to liquefy and dredge molten salt, or the heating coil 2 at the position of the temperature measuring device 4 can be disassembled and dredge to circulate liquid molten salt, so that the temperature of the buffer kettle body 1 at the position of the temperature measuring device 4 reaches the required high temperature.
In summary, when the molten salt flows through the heating coils 2 and the heat pipes 21 during operation, the heating tank 5 can heat the liquid molten salt flowing through the lower ends of the heat pipes 21, so that the liquid molten salt flows back to each heating coil 2 to maintain a high temperature state, and the buffer kettle body 1 is heated rapidly. When the buffer kettle body 1 is used again after being used in a suspended mode, high-temperature liquid circulates through the heat tracing pipe 3 to enable the heat tracing pipe 3 to form high temperature, so that the temperature is transferred to the heating coils 2, solid molten salt in each heating coil 2 is heated to be liquefied, the molten salt can form liquid state and can flow circularly, and therefore the circulating heating of the liquid molten salt is achieved, the buffer kettle body 1 is heated, and the operation is quite convenient.
The foregoing is merely illustrative of specific embodiments of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial modification of the present utility model by using the design concept shall fall within the scope of the present utility model.
