Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a hydrogen chloride organic solution packaging system. Background Art

[0002] Hydrogen chloride organic solution is produced by absorbing hydrogen chloride into alcohols, lipids or other organic solvents. Hydrogen chloride organic solution has both the flammability and explosiveness of organic solvents and the strong corrosiveness and strong acidity of hydrogen chloride. In addition, hydrogen chloride organic solution is highly volatile. As the temperature rises, the hydrogen chloride in the solution is easily volatilized. In addition, organic solvents such as alcohols also have a certain degree of volatility. Therefore, hydrogen chloride organic solution is not only harmful to operators during the manual packaging process, but also easily causes environmental pollution. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a hydrogen chloride organic solution packaging system for solving the problem that hydrogen chloride organic solution may cause great harm to operators during the manual packaging process.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0005] A hydrogen chloride organic solution packaging system comprises a solution storage tank, a loading pump and a barrel filling pump. The outlet end of the solution storage tank is connected to the inlet ends of the loading pump and the barrel filling pump respectively. The outlet end of the loading pump is equipped with a loading pipeline. The loading pipeline is equipped with a loading shut-off valve, a flow meter and a regulating valve in sequence and then connected to a loading crane pipe. The flow meter and the regulating valve are interlocked through a quantitative controller. The outlet end of the barrel filling pump is equipped with a barrel filling pipeline. The barrel filling pipeline is equipped with a barrel filling shut-off valve and then connected to a filling gun of an automatic barrel filling machine.

[0006] Furthermore, it also includes a nitrogen injector, which is connected to a nitrogen source, a material outlet of the nitrogen injector is connected to an exhaust processor, and a material inlet of the nitrogen injector is connected to an exhaust pipe. The exhaust pipe has two branches, one branch of the exhaust pipe is set on the pipe mouth of the loading crane pipe, and the other branch of the exhaust pipe is set on the muzzle of the filling gun on the automatic barrel filling machine.

[0007] Furthermore, a reflux pipe is installed at the outlet end of the solution storage tank, and the reflux pipe has two branches, one branch is connected to the outlet end of the loading pump through a loading reflux valve, and the other branch is connected to the outlet end of the barrel filling pump through a barrel filling reflux valve.

[0008] Furthermore, both ends of the loading cut-off valve are connected in parallel with a second loading safety valve.

[0009] Furthermore, it also includes a first loading safety valve and a barrel loading safety valve, one end of the first loading safety valve is connected to the outlet end of the loading reflux valve, and the other end of the first loading safety valve is connected to the loading pipeline, one end of the barrel loading safety valve is connected to the inlet end of the barrel loading cut-off valve, and the other end of the barrel loading cut-off valve is connected to the outlet end of the barrel loading reflux valve.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] (1) During the loading operation, the quantitative controller controls the opening size of the regulating valve through the flow data fed back by the flow meter to realize automatic loading.

[0012] (2) The nitrogen injector continuously blows nitrogen to the exhaust gas processor, forming a negative pressure in the two branches of the exhaust pipe, so that the volatile gas generated at the nozzle of the loading crane pipe and the nozzle of the filling gun is sent to the exhaust gas processor for treatment under the action of the negative pressure in the exhaust pipe, thereby preventing the volatile gas from affecting the working environment during the loading and barreling process;

[0013] (3) The reflux pipe can effectively ensure that the pressure of the hydrogen chloride organic solution in the solution storage tank remains stable during the transportation process. When the pressure is too high, it can be effectively diverted through the reflux pipe to reduce the pipeline pressure and improve the stability of the transportation of the hydrogen chloride organic solution.

[0017] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0018] A hydrogen chloride organic solution packaging system includes a solution storage tank 1, a loading pump 2, and a barrel filling pump 9. The outlet end of the solution storage tank 1 is connected to the inlet ends of the loading pump 2 and the barrel filling pump 9, respectively. The outlet end of the loading pump 2 is installed with a loading pipe 3. The loading pipe 3 is installed with a loading shut-off valve 4, a flow meter 19, and a regulating valve 18 in sequence, and is then connected to a loading crane pipe 8. The flow meter 19 and the regulating valve 18 are interlocked by a quantitative controller. The outlet end of the barrel filling pump 9 is installed with a barrel filling pipe 10. The barrel filling pipe 10 is installed with a barrel filling shut-off valve 11 and is connected to the filling gun of an automatic barrel filling machine 14. During the loading operation, the quantitative controller controls the opening size of the regulating valve 18 through the flow data fed back by the flow meter 19 to realize automatic loading. The operation only needs to determine the loading amount of the tank truck on the quantitative controller; during the barreling operation, an empty barrel is placed at the barrel inlet end of the automatic barreling machine 14, and the barreling pump 9 is started. The PLC controller of the automatic barreling machine 14 runs the automatic barreling program to perform the barreling operation. Both operation processes do not require real-time monitoring of the solution packaging progress, which reduces the risk of injury to the operators and improves the working environment.

[0019] The system further includes a nitrogen injector 15, which is connected to a nitrogen source. The material outlet of the nitrogen injector 15 is connected to an exhaust gas processor 17, and the material inlet of the nitrogen injector 15 is connected to an exhaust pipe 16. The exhaust pipe 16 has two branches, one of which is arranged at the nozzle of the loading crane pipe 8, and the other branch of the exhaust pipe 16 is arranged at the muzzle of the filling gun on the automatic barrel loader 14. The nitrogen injector 15 continuously blows nitrogen into the exhaust gas processor 17, forming a negative pressure in the two branches of the exhaust pipe 16. Therefore, the volatile gases generated at the nozzle of the loading crane pipe 8 and the muzzle of the filling gun are sent to the exhaust gas processor 17 for treatment under the action of the negative pressure, thereby preventing the volatile gases generated during the loading and barreling process from affecting the working environment.

[0020] The outlet of the solution storage tank 1 is also equipped with a reflux pipe having two branches: one branch connected to the outlet of the loading pump 2 via a loading reflux valve 5, and the other branch connected to the outlet of the barreling pump 9 via a barreling reflux valve 12. The reflux pipe effectively ensures that the pressure of the organic hydrogen chloride solution in the solution storage tank 1 is maintained stable during transportation. If the pressure is too high, the reflux pipe can effectively divert the flow, reducing the pipeline pressure and improving the stability of the transportation of the organic hydrogen chloride solution.

[0021] The two ends of the loading cut-off valve 4 are connected in parallel with a second loading safety valve 7 .

[0022] It also includes a first loading safety valve 6 and a barrel loading safety valve 13. One end of the first loading safety valve 6 is connected to the outlet end of the loading reflux valve 5, and the other end of the first loading safety valve 6 is connected to the loading pipeline 3. One end of the barrel loading safety valve 13 is connected to the inlet end of the barrel loading shut-off valve 11, and the other end of the barrel loading shut-off valve 11 is connected to the outlet end of the barrel loading reflux valve 12.

[0023] The automatic barrel filling machine 14 is a commonly used structure in the prior art, and has a control function, and can realize automatic transportation, automatic capping and automatic quantitative filling.

[0024] During loading operation:

[0025] (1) After the product tank truck arrives, align the nozzle of the loading crane pipe 8 with the feed port of the tank truck;

[0026] (2) Set the loading quantity through the quantitative controller, start the loading pump 2, and start loading;

[0027] (3) The volatilized gas during the loading process is extracted through the exhaust pipe 16 and sent to the exhaust gas processor 17 for treatment before being discharged in compliance with the emission standards;

[0028] (4) When the loading volume reaches the set value, the regulating valve 18 automatically closes, the loading pump 2 stops working, the loading crane pipe 8 is retracted, and the tank truck is sealed;

[0029] During barrel filling operation:

[0030] (1) Start the automatic barrel filling machine 14, put an empty barrel into the barrel inlet of the automatic barrel filling machine 14, start the barrel filling pump 9, and the PLC controller of the automatic barrel filling machine 14 runs the automatic barrel filling program to perform the barrel filling operation;

[0031] (3) The gas volatilized during the barrel filling process is extracted through the exhaust pipe 16 next to the filling gun nozzle and sent to the exhaust processor 17 for treatment before being discharged in compliance with the emission standards.

[0032] The utility model completes barreling and loading operations by automatic control means, and recovers and processes the volatilized gas during the packaging process, thereby avoiding direct or indirect contact between operators and materials, and solving the problems of easy environmental pollution and impact on the health safety of operators during the packaging process of hydrogen chloride organic solution.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
