Description

Technical Field

[0001] The invention relates to the technical field of hydrogen peroxide, and in particular to an automatic system for configuring a kettle for a hydrogen peroxide device. Background Art

[0002] As an important inorganic compound, hydrogen peroxide is also known as the "greenest and cleanest" chemical because its decomposition products are only water and oxygen, which is environmentally friendly. It is currently widely used in papermaking, textiles, sewage treatment, organic synthesis, electronics, metallurgy and other fields.

[0003] Among them, the preparation of working fluid is an important work process in hydrogen peroxide processing, which is usually completed by a preparation kettle. The working fluid is generally used in the following processes: the preparation of working fluid is required before the initial start-up, and it is used for alkali washing to recover some dirty working fluid after start-up, and it is used for cleaning the working fluid containing more alumina powder or waste aromatics containing more water-soluble degradation products at the bottom of the bleaching clay bed and the hydrogenated bleaching clay bed.

[0004] Since the domestic hydrogen peroxide device manufacturers currently use intermittent operation for washing working fluid, operators are forced to stay on-site for a long time in the hydrogen peroxide device (a major hazard source), which increases the workers' labor intensity and increases human operating errors (generally, most explosion accidents in the preparation process are caused by human operating errors), resulting in great safety risks in the operation.

[0005] The preparation kettle in the existing hydrogen peroxide processing production line can only provide working liquid preparation work, and cannot provide automatic cleaning and recycling operation adjustment for the waste generated in each process. At the same time, manual operation is frequent during the operation, and the stay time on site is long, which increases the labor intensity of workers and leads to a high probability of human-caused operational errors. Therefore, an automatic system for the preparation kettle of hydrogen peroxide device is proposed. Summary of the invention

[0006] In view of the problems in the prior art, the present invention provides an automated system for a preparation kettle of a hydrogen peroxide device, in which various pipelines connected to the preparation kettle can be automatically controlled and adjusted, and materials such as anthraquinone can be automatically discharged and supplied, thereby reducing the frequency of valve switching by on-site personnel, greatly reducing the demand for on-site manual operation, and adding an emergency discharge interlock system.

[0029] Preparation of working solution:

[0030] Step 1: The central control host issues working fluid preparation commands to the cut-off valves on the boundary aromatics pipeline, tetrabutyl urea pipeline, trioctyl phosphate pipeline, desalted water pipeline, star unloader, acid working fluid pipeline, drain pipeline, steam pipeline and desalted water temperature distribution pipeline in sequence;

[0031] Step 2: The shut-off valve on the boundary aromatics pipeline is opened to allow the boundary aromatics to enter the preparation kettle.

At the same time, start the agitator of the preparation kettle to stir and clean the incoming materials. After cleaning, let the preparation kettle stand for 15-20 minutes to allow water and oil to separate into layers in the preparation kettle.

[0036] Step 7: Then the shut-off valve and regulating valve of the liquid discharge pipeline and the grease trap are opened successively, so that the water layer at the bottom of the preparation kettle is first discharged into the grease trap through the liquid discharge pipeline. During this period, the sewage sight glass on the liquid discharge pipeline is monitored in real time by a camera.

[0041] Step 2: The shut-off valve on one of the waste aromatics pipeline, coalescer pipeline, clay bed pipeline or working liquid storage tank pipeline in the operation device is opened, so that one of the substances that need to be washed with water in the waste aromatics storage tank, coalescer, clay bed or working liquid storage tank is sent into the preparation kettle, and the liquid level change after the substance enters is detected by the liquid level sensor on the preparation kettle. After the liquid level reaches the value set by the personnel, the shut-off valve is closed;

[0042] Step 3: The shut-off valve on the desalted water pipeline is opened to allow the desalted water to enter the preparation kettle. After the liquid level in the preparation kettle reaches the value set by the personnel, the shut-off valve on the desalted water pipeline is closed;

[0043] Step 4: The steam pipeline is opened to allow steam to enter the heating jacket of the preparation kettle, and the preparation kettle is heated to 50°C. At the same time, the agitator of the preparation kettle is started to stir and clean the incoming materials. After the cleaning is completed, the preparation kettle is left to stand for 15-20 minutes to allow water and oil to be separated into layers in the preparation kettle;

[0044] Step 5: Then the shut-off valves and regulating valves of the drainage pipeline and the grease trap are opened successively, so that the water layer sinking to the bottom of the preparation kettle is discharged into the grease trap through the drainage pipeline first. During this period, the sewage sight glass on the drainage pipeline is monitored in real time by the camera. When the color of the sewage passing through the sewage sight glass changes to oil, the regulating valve of the grease trap is closed. At the same time, the shut-off valves on the treatment pipeline and the working fluid pump are opened to pump the oil into the filter, and after filtration, it enters the fresh working fluid storage tank for standby.

[0045] Beneficial effects of the present invention: the present invention uses the central control host in the work site to automatically control and adjust various pipelines connected to the preparation kettle, automatically discharge and supply materials such as anthraquinone, reduce the frequency of valve switching by on-site personnel, greatly reduce the demand for on-site manual operation, and increase the emergency discharge interlock system. When the temperature in the preparation kettle rises abnormally, the material in the preparation kettle can be urgently discharged through the accident pool pipeline, reducing the manual reaction time, thereby reducing the risk of over-temperature explosion of the preparation kettle, improving the safety performance of the device, and solving the problem that the preparation kettle in the existing hydrogen peroxide processing production line can only provide working liquid preparation work, and cannot provide automatic cleaning and recovery operation adjustment for waste generated in each process. At the same time, manual operation is frequent during operation, the stay time on site is long, the labor intensity of workers is increased, and the probability of human-induced operational errors is high.
