It is mainly used to hold various types of fillers and can be used for multi section connection. The lower grinding port is connected to the tower kettle, and the upper grinding port is connected to the tower head. It is the main place for gas-liquid exchange in the system. Temperature measurement points and feeding ports can be set up in the middle

The non segmented sieve plate supported by the packing is supported by a threaded stainless steel ring, making it detachable and easy to replace or clean the packing.

Distillation packing

Stainless steel θ ring packing:θ ring packing, also known as Dixon packing, is a small particle high-efficiency packing made of metal wire mesh, with a diameter equal to its height. θ ring packing is mainly used in laboratory and small batch, high-purity product separation processes. The pressure drop of the θ ring packing is related to factors such as gas velocity, liquid spray rate, system density, surface tension, viscosity, and the characteristics of the packing, as well as the amount of pre flooding treatment of the packing. The hysteresis of θ ring fillers is greater than that of similar solid fillers, and the surface wetting condition is also higher than that of general ceramic rings. The film formation rate is also higher, resulting in higher separation efficiency. The theoretical plate number of θ ring packing increases with the increase of gas velocity, while decreasing with the decrease of surface wetting rate of the packing.

Glass spring packing:Glass spring packing is mainly used in the packing tower of laboratory distillation equipment in industries such as fine chemicals and pharmaceuticals. It has the characteristics of corrosion resistance and high filtration efficiency. The diameter and length of this product can be designed and manufactured according to user requirements. Conventional products have a diameter of 3 to<8mm and a length of 6 to<20mm. The diameter of the standard glass spring packing is less than 4mm, the length is 10 to 20mm, and the theoretical number of trays is 10 to 20 pieces per meter. Glass spring packing is mainly used for corrosive materials such as organic acids. Some systems do not allow contact with iron ions, and glass spring packing is the preferred packing for laboratories. It can be used for research and experimentation in fields such as organic chemistry, petrochemicals, fine chemicals, biopharmaceutical chemistry, and new product development.

Triangular spiral packing:It is made of metal wire and has a shape similar to a spring, also known as triangular spring packing. The difference between it and a spring is that each circle wound around it is not circular but triangular, and the triangles between the circles are offset by a certain angle, so it is a polygon when viewed from the end face direction. This type of packing has higher efficiency, but slightly higher resistance compared to annular packing, and is widely used in laboratory scale isotope separation research.

There are various specifications of packing materials, and different distillation packing materials are selected according to different experimental environments of customers

condenser

The important component of distillation test operation, which controls the extraction and reflux of the system. The lower part is controlled by an electromagnet to swing the solenoid valve for the purpose of reflux and extraction. The extracted part is collected with the extraction tube, and the reflux part is refluxed through the lower connecting tower section, which is equipped with a temperature measuring port. The upper part istubularCondenser, equipped with a temperature measuring portAnd a reflux sealing design was made, effectively preventing the disorderly mixing of the extracted sample and the reflux sample.

Reflux ratio control system

Make an electromagnet based on electromagnetic principles, and use a double delay relay to control the iron drop inside the suction tower head of this electromagnet to achieve reflux and extraction

System pressure control system

This system controls the vacuum degree of the distillation system and reduces the boiling point of the distillation components. The vacuum degree of this device can be adjusted according to customer needs, and the small vacuum degree can reach 1mmHg

control cabinet

The entire control cabinet mainly includes temperature digital display instruments, pressure digital display instruments, reflux ratio controllers, regulators, heating indicator lights, temperature abnormal alarm instruments, etc. It mainly characterizes and reflects the situation of various control points in the distillation process, and the number and location of control points can be designed according to customer needs. For example, a temperature digital display can measure tower kettle temperature, tower top temperature, tower section temperature, etc. through temperature sensors. The pressure regulator can control tower kettle heating, tower section insulation heating, etc. In addition, the control cabinet can also be used as a data acquisition system, displaying all data during the distillation process through a digital LCD screen and recording all process data in the control cabinet chip. Experimental data can be collected through a USB flash drive and stored in specific computer software for storage and filing.
