In the chemical production process, the device that provides the reaction space and reaction conditions for the chemical reaction is called the reaction kettle. The reaction kettle is a container that provides physical or chemical reactions. Through structural design and parameter configuration, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Except for some general chemical machinery and equipment. Reactor is the key equipment in chemical production.
XX Industrial Co., Ltd. is a service provider that develops, manufactures and sells various chemical products such as pigments, hydrochloric acid, dye intermediates, dye products, chemical products, plastic products, and daily chemical products. The company covers an area of 120,000 square meters, specializing in the research and development and production of various chemical products. At present, there are more than 100 technicians of various types, including more than 20 middle and senior technicians including doctors. At the same time, it has established long-term cooperative relations with many colleges and universities, and has strong R&D, production and management capabilities. In recent years, after continuous development and improvement, it has passed the ISO9001 international quality system certification, and has a number of GMP-compliant product production lines and workshops.
In the production process, XX Company found that the internal temperature of the reaction kettle is often too high due to the internal reaction of various chemical reagents, and the chemical reaction of the material in the reaction kettle must be carried out at a relatively stable temperature, otherwise it will be It is possible to reduce the quality and production efficiency of the produced products, and in severe cases, it may lead to production failure and bring great losses to the enterprise.
Take the pigment chemical reaction kettle as an example.
In the production of organic pigments, the reaction of aromatic primary amines and nitrous acid (in a strong acid medium) to generate diazonium salts is called diazotization.
Among them, the cis-method diazotization is to add an appropriate amount of water to the chromophore to mix, then add a specified amount of hydrochloric acid, and slowly add sodium nitrite at low temperature and under constant stirring to complete the diazotization reaction. The diazotization temperature is 5-10°C, and the time is about 10 minutes. If the reaction temperature is too high and the reaction time is too short, a better diazotization result cannot be obtained.
In this process, the most ideal cooling method is to use artificial ice or cold water to cool down, so as to control the reaction temperature of the whole process.
XX company found Bingquan refrigeration, hoping to solve this problem with the help of Bingquan. After receiving this demand, Bingquan Refrigeration quickly formed a professional team, and after timely understanding and confirming other details such as chemical production output and workshop site, it was suggested that XX company should be equipped with a 20-ton brine ice block machine and an ice crusher.
The ice block machine is one of the ice machines. The ice cubes produced are the largest in size among ice products, and are not easy to melt.
Bingquan Refrigeration is a pioneer in the large-scale fluorine refrigeration ice block machine industry. It has developed and manufactured the world's first large-scale fluorine refrigeration ice block machine with a daily output of 100 tons of ice and successfully operated in Malaysia in 2010. The daily ice output of a single (set) of equipment ranges from 1 ton to 200 tons, which can meet the needs of different customers.
Bingquan Refrigeration Ice Crusher is an ice device specially designed for large ice cubes. It is easy to operate and reliable. There are special ice clips and anti-ice rebound baffles inside the machine. The whole is made of 304 stainless steel, which has strong corrosion resistance and has a service life of more than 10 years.
After using the equipment for a period of time, XX company feedback that the quality of our ice bricks is very good, the hardness is high and it is not easy to melt. The supporting equipment, the ice crusher, is also very convenient to use and easy to operate. The ice breaking process is very smooth and will not get stuck. The crushed ice can quickly cool down the reactor, ensuring that the chemical reaction is carried out at a stable temperature.
Horses are paired with saddles, and chemical reactions are paired with ice!
