In the chemical production process, the device that provides reaction space and reaction conditions for chemical reactions is called a reactor. The reactor 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. In addition to some general chemical machinery and equipment. The 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 and specializes in the development and production of various chemical products. At present, there are more than 100 technical personnel of various types, including more than 20 middle and senior technical personnel including doctors. At the same time, it has established long-term cooperative relations with many universities and colleges and research institutes, 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 reactor is often too high due to the internal reaction of various chemical reagents, and the chemical reaction of the materials in the reactor must be carried out at a relatively stable temperature, otherwise It may reduce the quality and production efficiency of the products produced, and in severe cases, it may cause production failures 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 primary aromatic amines and nitrous acid (in a strong acid medium) to form diazonium salts is called diazotization. The cis-method diazotization is to add an appropriate amount of water to the color base, and then add the specified amount of hydrochloric acid, and slowly add sodium nitrite under low temperature and constant stirring to complete the diazotization reaction. The diazotization temperature is 5-10℃, and the time is about 10min. If the reaction temperature is too high and the time is too short, good diazotization results cannot be obtained.In this process, the most ideal cooling method is to use artificial ice or cold water cooling to control the reaction temperature of the whole process.XX company found CBFI Guangzhou Bingquan Refrigeration, hoping to solve this problem with the help of Bingquan. After receiving this demand, CBFI Guangzhou Bingquan  Refrigeration quickly formed a professional team to timely understand and confirm other details such as chemical production output and workshop site.

Convenience, safety and reliability.The general design requirements of the cold storage room for civil construction are as follows　　1. The cold storage room should be an independent building and be arranged near the refrigeration load center, close to the cold room with the largest refrigeration load, but not close to the main traffic arteries of the storage area;       2. In terms of general layout, the cold storage room should be in the downwind direction of the dominant wind direction in summer, but in the production area, it should generally be arranged in the upwind direction of the boiler room, coal yard and other places prone to smoke and dust; at the same time, the cold storage room It should also be located in the upwind direction of the cooling tower, and the spacing should not be less than 25m;　　3. The cold storage room should not be close to crowded places (such as dormitories, kindergartens, canteens, clubs, etc.), and ammonia pipes should not pass through the above rooms to avoid casualties in the event of a major accident;　　4. The area of the cold storage room is mainly determined by considering the layout and operation of the machine and equipment. Generally, it can be considered as about 5% of the production area of the cold storage. Specific issues such as the building form, structure, span, height, size and distribution of doors and windows of the computer room are best negotiated by the refrigeration process designer and the relevant building designer;　　5. The height of the cold storage room should take into account factors such as the air conditioning equipment and the convenience of drawing out the piston connecting rod when the compressor is overhauled, and should take into account the requirements of ventilation and lighting. Generally, the net height of a large and medium-sized cold storage room can be 6.5-7m, and the net height of a small cold storage room can be 5-5.5m. The large and medium-sized cold storage room in the southern area should be equipped with a ventilated attic, and pay attention to the direction and surroundings, and be sure to obtain good natural ventilation and natural lighting conditions;　　6. In order to ensure the safety and convenience of the operators, the passage in the cold storage room should not be too long, preferably no more than 12m, but when the large computer room exceeds 12m, two or more entrances and exits that are not adjacent to each other and directly lead to the outdoors are required. The width of the doorway is not less than 1.5m, and the width of one doorway should be able to ensure access to the largest equipment;　　7. All doors and windows of the cold storage room should be designed to open outwards, and use side-hung doors. Side sliding doors are prohibited, so that people can escape from danger in an emergency. The door of the ammonia compressor machine room is not allowed to lead directly to the production workshop. The machine room must have good natural lighting. The light projection area of its windows is usually not less than 1/7~1/6 of the floor area. Such measures should be taken in the hot season. , Avoid direct sunlight;　　 8. In order to prevent oil immersion and facilitate cleaning, the surface of the cold storage room floor, wall skirt and machine base is generally made of cast-in-place grindstone surface. Oil pumps, liquid pumps, low-pressure oil collectors and other equipment bases shall be provided with shallow drainage ditches;　　9. According to the "Code for Fire Protection Design of Buildings" promulgated by the country, the ammonia compressor room is a Class B hazardous production building and should be designed for buildings with ammonia level II fire resistance.

The epidemic caused by the new crown virus is still raging around the world, and it is gratifying that many countries have been actively developing new crown vaccines. To achieve herd immunity against the new coronavirus on a global scale, the only way at present is to vaccinate.Vaccines refer to vaccine-like preventive biological products used for human vaccination in order to prevent and control the occurrence and prevalence of infectious diseases. It is of great significance to the protection of human health, and it is more related to the national economy, people's livelihood and people's life and health. At the same time, because vaccines are biological agents prepared from microorganisms or their toxins, enzymes, human or animal serum, cells, etc., for prevention, diagnosis, and treatment, they need to be suitable during their production, storage, transportation, and use. Temperature conditions provide corresponding protection to ensure the immune effect of the vaccine. Vaccines are fragile biological products that are very sensitive to temperature. If the vaccine is not stored properly, the active protein and other substances in the vaccine will disappear, and it is likely to become a useless vaccine, causing harm to the vaccinated population. Therefore, the suitable storage environment temperature of most vaccine biological products needs to be controlled at 2~8℃ throughout the whole process, and some biological products have lower requirements for environmental temperature up to -20℃. Guangzhou Bingquan Refrigeration Equipment Co., Ltd. has been focusing on the refrigeration industry for more than ten years.
