This method can safely lower the temperature, but it wastes a lot of water, electricity, especially time, such as cooling 3 tons of water for injection at 80 degrees Celsius to 50 degrees Celsius with 32 degrees Celsius cooling water (summer water temperature provided by the cooling tower) , it takes at least 1 hour, not suitable for continuous and mass production
The second is to install a heat exchanger under the U-shaped diaphragm valve. If there are several points that need to use low-temperature water for injection, several heat exchangers need to be installed. This method can quickly lower the temperature, but the pipeline, The investment in the valve is increased, and the purification area is very messy, and it is easy to cause misoperation

Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawing.
[0010] A high-temperature water online rapid cooling system, high-temperature injection water supply equipment water supply port ( figure 1 The middle is: water for injection supply) is connected with the first tee 6 and the water for injection inlet 7 of the heat exchanger 9 through the pipeline in turn, and the water for injection outlet 8 of the heat exchanger is connected with 1-9 water for injection through the pipeline in turn. After one end of the sanitary diaphragm valve 14 is connected, the third tee 10, the second sanitary diaphragm valve 2, and the second tee 11 are connected to the return port of the high-temperature water for injection water supply equipment ( figure 1 The middle is: injection water return); the first sanitary diaphragm valve 1 is set between the first tee and the second tee, and the third sanitary diaphragm valve 3 is connected to the third te...

The invention discloses an online quick cooling system of high-temperature water. High-temperature injection water supply equipment is connected with a first T-joint and the injection water inlet of a heat exchanger in sequence; the injection water outlet of the heat exchanger is connected with one end of a healthy diaphragm valve for material distribution through a pipeline and also connected with the high-temperature injection water supply equipment through a third T-joint, a second healthy diaphragm valve and a second T-joint in sequence; a first healthy diaphragm valve is arranged betweenthe first T-joint and the second T-joint; the third T-joint is connected with a third healthy diaphragm valve for emptying; the water supply inlet of cooling water supply equipment is connected with a first stop valve and the cooling water inlet of the heat exchanger through pipelines in sequence; and the cooling water outlet of the heat exchanger is connected with a second stop valve and the water returning opening of the cooling water supply equipment through pipelines in sequence. The online quick cooling system of high-temperature water is low in cost, simple in structure and convenient in operation, and saves a large amount of time and improves the labor productivity.
Description
technical field [0001] The invention relates to a high-temperature water online rapid cooling system. Background technique [0002] At present, according to the requirements of the "Guidelines for Drug Production Verification (2003)" issued by the State Food and Drug Administration, domestic pharmaceutical companies have the following requirements for water for injection (excerpt): The pipeline distribution system must be a circulation loop, and the heat preservation cycle above 80°C , The length of the "blind pipe" section in the system shall not be greater than 6 times the pipe diameter and other requirements. [0003] According to the above regulations, the temperature of the water for injection released from the valve at the point of use should be at 80°C. If the medicines used for dispensing (in fact, most medicines) are sensitive to heat, it is necessary to cool the high-temperature water for injection to the temperature required by the process, generally at 50°C Ther...
