Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a device and a system for removing volatile gas phase components. Background Art

[0002] In the process of preparing rubber products, due to the presence of volatile components in rubber and auxiliary materials, rubber products have some special odors during production and use. In order to improve the quality of rubber products, volatile components need to be removed by separation and purification during the preparation of rubber and auxiliary materials to avoid residues in the product and produce odor. The temperature for removing volatile components is generally controlled between 50-250℃, and the specific temperature is related to the properties of rubber products and volatile components. The pressure for removing volatile components varies greatly and can be carried out at a pressure of several Pa to tens of bars absolute pressure, which mainly depends on the physical properties of the volatile components contained in the rubber products and the requirements of the product itself. In the process of removing volatile components, the separation between the product and the volatile components is based on the difference in volatility of the two under the same conditions, and is driven by the difference in chemical potential between the two. The chemical potential of volatile components in rubber products is a function related to temperature, concentration and pressure in a specific phase. The driving force for mass transfer can be enhanced by increasing the temperature of the material and reducing the partial pressure of the substance to diffuse it from the rubber product to the gas phase. At present, the methods for removing volatile components in the preparation process of rubber products include kettle or tower atmospheric and vacuum cascade distillation, steam or inert gas stripping, flash evaporation and the like.

[0003] However, in the process of removing volatile components by kettle or tower, as the content of volatile components gradually decreases, the diffusion area of ​​volatile components continues to decrease, and the difficulty of removal increases accordingly. The existing conventional kettle or tower atmospheric and vacuum cascade distillation, steam or inert gas stripping, flash evaporation and other methods can only reduce the content of volatile components in the product to about 150-500ppm. However, with the increasingly stringent environmental protection requirements and people's higher and higher requirements for product quality, the content of volatile substances in rubber products and their additives needs to be controlled below 50-100ppm, and the current method of removing volatile components obviously cannot meet this requirement.

[0004] Therefore, the current devices and systems for removing volatile gas phase components still need to be improved. Utility Model Content

Then, the material is allowed to enter the preheating unit 100 from the material inlet 110. Inside the preheating unit 100, the material can be preheated to 50°C-300°C. The specific temperature can be determined according to the boiling point of the volatile components in the material. Then, the preheated material flows out from the preheating material outlet 120, flows down in strands under the action of the drainage pipe 150, and then is further dispersed by the conical disperser 160, so that part of the volatile components in the material are separated through the dispersed material surface; the dispersed material flows to the heating distribution plate 230 again, is further dispersed and heated under the action of the heating distribution plate 230, and the volatile gas phase components are further removed. After the heating treatment of multiple heating distribution plates 230, the material flows into the bottom of the separation unit 200, and is discharged from the material outlet to the material extraction pipe 312 for extraction, or is circulated to the material inlet 110 under the action of the recycling pump 320 to repeat the volatile component removal treatment, which further increases the residence time of the material inside the device and improves the separation efficiency.

[0055] In general, the device and system for removing volatile gas phase components proposed in the utility model utilize the preheater 130 in the preheating unit 100 and the heating distribution plate 230 with heating function in the separation unit 200 to increase the contact area between the device and the material, thereby increasing the residence time of the material inside the device, allowing the volatile components to diffuse better and improving the removal efficiency. A circulation loop is formed by utilizing the circulation unit 300 to circulate the degassed material to the material inlet 110, and the removal of volatile gas phase components is repeated. The content of volatile gas phase components in the separated material can reach below 50-100 ppm, and no steam and inert gas stripping is required during the entire removal process, and energy consumption and material consumption are greatly reduced.

[0056] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
