Description

Technical Field

[0001] The utility model relates to a jacketed container heat exchange pipeline system, belonging to the technical field of heat exchange pipelines. Background Art

[0002] In the production of cellulose products, it is necessary to use a jacketed reactor vessel for the reaction. The cooling and heating sources of the reactor, such as chilled water and hot water, are all centrally supplied by the factory's public works pump station. The piping system diagram can be found in the following figure. Figure 1 The heat exchange jacket of the jacketed container is connected to a heat exchange medium inlet pipe and a heat exchange medium outlet pipe. The end of the heat exchange medium outlet pipe away from the heat exchange jacket has a system supply outlet, and the heat exchange medium inlet pipe is directly connected to the heat exchange medium supply source (depending on the working conditions of the equipment, it is connected to chilled water or hot water).

[0003] During daily production and use, due to the simultaneous use of multiple jacketed containers, it is inevitable that the supply flow rate of some jacketed containers will slow down, affecting the heat exchange efficiency of the heat exchanger container and reducing production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a jacketed container heat exchange piping system with higher heat exchange efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a jacketed container heat exchange piping system, including a jacketed container, a buffer container and a water pump, the outer wall of the jacketed container is provided with a heat exchange jacket, the heat exchange jacket is connected to a heat exchange medium inlet pipe and a heat exchange medium outlet pipe, the heat exchange medium outlet pipe has a system supply outlet at one end away from the heat exchange jacket, the heat exchange medium inlet pipe includes a first pipe and a second pipe, one end of the first pipe is connected to the heat exchange jacket, and the other end is connected to the outlet end of the water pump, one end of the second pipe is connected to the heat exchange medium supply source, and the other end is connected to the inlet end of the water pump, the buffer container is connected to the middle of the heat exchange medium outlet pipe through a third pipe, and is connected to the middle of the second pipe through a fourth pipe, the position height of the connection point between the third pipe and the heat exchange medium outlet pipe is lower than the position height of the system supply outlet, and the overall position height of the third pipe is not higher than the position height of the system supply outlet.

[0006] The beneficial effect of this utility model is that after the cold or heat source supplied by the system is drawn into the heat exchange jacket by the water pump, it will preferentially enter the buffer container at the outlet of the heat exchange jacket because the discharge pressure at the end of the system is higher than the pressure entering the buffer container. The buffer container ensures the water supply of the water pump and prevents damage to the water pump. After implementation of this utility model, the jacket system of the jacket container forms an internal circulation system. The external supply is accelerated by the internal circulation system and then discharged out of the heat exchange jacket. This does not affect the original supply system, but increases the flow rate of the heat exchange medium in the heat exchange jacket, thereby improving heat exchange efficiency.

[0009] Parts marked in the figure: jacketed container 1, heat exchange jacket 2, heat exchange medium inlet pipe 3, heat exchange medium outlet pipe 4, buffer container 5, water pump 6, system supply outlet 7. DETAILED DESCRIPTION

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] like Figure 2 As shown, the utility model includes a jacketed container 1, a buffer container 5 and a water pump 6. The outer wall of the jacketed container 1 is provided with a heat exchange jacket 2. The heat exchange jacket 2 is connected to a heat exchange medium inlet pipe 3 and a heat exchange medium outlet pipe 4. The heat exchange medium outlet pipe 4 has a system supply outlet 7 at one end away from the heat exchange jacket 2. The heat exchange medium inlet pipe 3 includes a first pipe and a second pipe. One end of the first pipe is connected to the heat exchange jacket 2 and the other end is connected to the outlet end of the water pump 6. One end of the second pipe is connected to the heat exchange medium supply source and the other end is connected to the inlet end of the water pump 6. The buffer container 5 is connected to the middle part of the heat exchange medium outlet pipe 4 through the third pipe ("the middle part of the heat exchange medium outlet pipe 4" generally refers to the heat exchange jacket). 2 and the system supply outlet 7), the buffer container 5 is connected to the middle of the second pipe via a fourth pipe ("the middle of the second pipe" generally refers to the upstream area of ​​the inlet end of the water pump 6). The height of the connection point between the third pipe and the heat exchange medium outlet pipe 4 is lower than the height of the system supply outlet 7, and the height of the entire third pipe is no higher than the height of the system supply outlet 7. The height difference formed here ensures that the system end discharge pressure at the outlet of the heat exchange jacket 2 is higher than the pressure entering the buffer container 5, thereby allowing the heat exchange medium at the outlet of the heat exchange jacket 2 to enter the buffer container 5 first. The buffer container 5 ensures the water supply of the water pump 6 to avoid damage to the water pump 6. The water pump 6 can increase the flow rate of the heat exchange medium in the heat exchange jacket 2, thereby improving the heat exchange efficiency.
