Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically to an environmentally friendly, anti-clogging distillation tower for chemical production. Background Technology

[0002] Environmentally friendly chemical production refers to a production method that follows the concepts of green chemistry and sustainable development in the chemical production process, adopts advanced technologies and management measures, and aims to reduce environmental pollution and improve resource utilization efficiency. It promotes the recycling of materials in chemical production, such as wastewater reuse and waste gas resource utilization, establishes a recycling and reuse system for waste chemicals, strengthens the whole life cycle management of products, and reduces the mining of raw materials and environmental pollution.

[0003] A distillation column is the main equipment used to perform distillation operations. Based on the differences in boiling points of the components in a liquid mixture, the mixture is heated to its boiling point inside the column. The lighter components with lower boiling points evaporate first, forming vapor that rises within the column; while the heavier components with higher boiling points remain in the liquid, which flows downwards under gravity. With the counter-current flow of the gas and liquid phases within the column, multiple heat and mass exchanges occur at different heights on the trays or packing. Lighter components continuously transfer from the liquid phase to the gas phase, while heavier components transfer from the gas phase to the liquid phase, thus achieving the separation of the components in the mixture.

[0004] However, in actual use, the aforementioned anti-clogging distillation towers for environmentally friendly chemical production are prone to problems. On the one hand, liquid impurities easily clog the flow holes during the downward sedimentation reaction, making it difficult for the equipment to be used for a long time. On the other hand, traditional anti-clogging devices are cumbersome in construction, and the clogging intervention usually occurs during the reaction stage, which can easily affect the subsequent use of the equipment. Therefore, we propose an anti-clogging distillation tower for environmentally friendly chemical production. Summary of the Invention

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. In this invention, a scraper is installed inside the discharge hopper. The linkage structure at the top of the discharge hopper drives the internal scraper to rotate and grind. After the motor on one side of the device drives the internal rotating disc to rotate, the distilled liquid flows into the discharge hopper from the top side of the device. The rotating component can finely crush the impurities in the distilled liquid, avoiding blockage after multiple sedimentation reactions. The overall anti-blockage structure is simple, easy to install, and highly practical. The rotation of the rod can not only prevent blockage but also stir the distilled liquid a second time, thereby improving the overall practical effect of the device.

[0019] 2. In this invention, by providing a discharge hopper on the side of the bottom shell near the upper shell and placing the discharge hopper inside the upper section of the bottom shell, the residual impurities in the device are finely crushed and intervened from the source of the distilled liquid flow, thereby avoiding blockage after the device is recycled. Grinding operations are prone to wear on the internal structure of the components, and the installation on the top of the device also facilitates the later maintenance of the components.

[0020] 3. In this invention, by installing an air vent plate on the side of the upper shell near the bottom shell and placing the air vent plate inside the bottom of the upper shell, the liquid being distilled will generate a large amount of gas. The large amount of gas drifts upward to avoid high gas pressure inside the device. In addition to setting a pressure valve, the air vent plate inside the device can slow down the upward flow rate of the gas and can also condense the distillate generated by the large amount of gas. After settling downward, it can be discharged from the device, thereby improving the overall stability of the device. Attached Figure Description

[0033] Working principle of this invention:

[0034] First, the distilled liquid flows from the top side of the device into the discharge hopper 5. A scraper 305 is installed in the discharge hopper 5. The linkage structure at the top of the discharge hopper 5 drives the internal scraper 305 to rotate and grind. The motor 3 on one side of the device drives the internal rotating disk 303 to rotate. The rotating component can finely crush the impurities in the distilled liquid to avoid clogging after multiple sedimentation reactions. The overall anti-clogging structure is simple and easy to install, and it is highly practical. The rotation of the rod can not only prevent clogging, but also stir the distilled liquid a second time.

[0035] Secondly, a reaction layer 6 is provided on the side of the distributor 501 away from the upper shell 1, and the reaction layer 6 is placed inside the bottom shell 2. A mounting bracket 602 is installed on the side of the reaction layer 6 near the bottom shell 2. A packing 601 is installed on the side of the reaction layer 6 near the discharge hopper 5. A top mounting component 604 is installed on the side of the reaction layer 6 away from the packing 601, and the top mounting component 604 is placed in the center of the reaction layer 6 and fixedly connected to the reaction layer 6. A distributor 603 is fixedly connected on the side of the top mounting component 604 away from the reaction layer 6. A reaction layer 7 is provided on the side of the distributor 603 away from the reaction layer 6, and the reaction layer 7 is placed inside the bottom shell 2 and fixedly connected to the bottom shell 2. After the distilled liquid undergoes a secondary reaction to form a liquid with higher purity, it is discharged through the discharge pipe 201.

[0036] Then, by installing an air vent plate 8 on the side of the upper shell 1 near the bottom shell 2, and placing the air vent plate 8 at the bottom of the inner part of the upper shell 1, the liquid being distilled will generate a large amount of gas. The large amount of gas will drift upward to avoid the large gas pressure inside the device. In addition to setting a pressure valve, the air vent plate 8 inside the device can slow down the upward flow of gas and can also condense the distillate generated by the large amount of gas. After settling downward, it can be discharged from the device.
