China glass lined equipment

Glass lined equipment occupies an important position in China's industrial field,and with its unique performance advantages,it is widely used in multiple industries such as chemical,pharmaceutical,and food.The working principle of China glass lined equipment is of great significance for improving equipment efficiency,ensuring production safety,and promoting further development of related industries.
China glass lined equipment mainly consists of kettle body,kettle cover,agitator,transmission device,shaft seal device and other parts.The kettle body is usually made of carbon steel or stainless steel material,and the internal surface is coated with a layer of glass glaze.This layer of glass glaze not only endows the equipment with good corrosion resistance,but also gives it a smooth surface that is not easily adhered to materials and is easy to clean.The kettle cover is equipped with a pressure gauge,bursting disc safety device,vapor-liquid phase valve,temperature sensor,etc.,which facilitates the understanding of the reaction situation inside the kettle at any time,adjusts the proportion of the medium inside the kettle,and ensures safe operation.The mixer is driven by a servo motor through a coupling,and the speed of the servo motor is controlled to achieve the purpose of controlling the mixing speed.The transmission device is responsible for transmitting the power of the motor to the mixer,while the shaft seal device is used to prevent material leakage inside the kettle.
The chemical reactions carried out in China glass lined equipment mainly rely on the enclosed environment provided by the equipment and suitable reaction conditions.The enamel layer has excellent corrosion resistance and can work normally in harsh environments such as acidic,alkaline,and organic solvents,protecting the reaction vessel from chemical corrosion by reactants.For example,in plastic production,the polymerization reaction of polyvinyl chloride(PVC)is often carried out in a glass lined reactor;In the pharmaceutical industry,the production of antibiotics and the extraction of active ingredients from traditional Chinese medicine also rely on glass lined reaction vessels.By adding different reactants,these reactions can proceed smoothly under certain temperature,pressure,and stirring conditions.At the same time,the smooth surface of the enamel layer helps with the flow of materials and the uniformity of reactions,improving the efficiency and quality of chemical reactions.
Glass lined equipment controls the temperature of the reactants through an external heating or cooling system to meet the temperature requirements of different chemical reactions.Taking jacket heating as an example,when the temperature measured by the temperature measuring device is lower than the set value,the steam regulating valve is opened to increase the water temperature inside the jacket,and at the same time,the temperature of the material in the reaction kettle is increased;When the temperature measured by the temperature measuring device is higher than the set value,the China glass lined equipment opens the cooling water regulating valve to cool the water temperature inside the jacket,reduce the temperature of the materials in the reaction kettle,and then stabilize the temperature inside the reaction kettle within the set range,allowing the reaction to proceed smoothly.This heat transfer method can ensure that the reaction proceeds under suitable temperature conditions,improve the reaction rate and selectivity,while avoiding reaction failure or the production of by-products due to excessively high or low temperatures.
The agitator plays a crucial role in China glass lined equipment,as it rotates to thoroughly mix the materials inside the kettle.There are various types of agitators,such as anchor type,frame type,push type,etc.Different types of agitators are suitable for different material characteristics and reaction requirements.For example,anchor mixers are suitable for materials with high viscosity and strong stirring force;Frame mixers have unique advantages under certain specific operating conditions.The speed,shape,and installation position of the mixer can all affect the mixing effect of the material.Reasonable mixing design can evenly distribute materials,improve heat and mass transfer efficiency,and promote chemical reactions.At the same time,the stirring process can also avoid local overheating or undercooling of the material,ensuring the stability and consistency of the reaction.
