Example Embodiment

[0027] Example 1:

[0028] When we let the temperature control system start to work, first start the water bath heating module, use industrial steam for heating, first manually open the sanitary ball valve VBH613, the industrial steam pneumatic angle valve VPG607 automatically adjusts the opening according to the set temperature, and then the industrial steam passes through the industry The steam-pneumatic angle valve VPG607 reaches the plate heat exchanger WK-HE-401, and exchanges heat through the plate heat exchanger WK-HE-401. The hot water is heated to the set temperature, and the plate heat exchanger WK-HE- The hot water in 401 absorbs the superheated industrial steam to liquefy, and then flows out of the plate heat exchanger WK-HE-401 to the chilled water pneumatic angle valve VPG611, and then passes through the condensate pneumatic angle valve VPG608 and then is filtered by the filter F602, and then in turn After the steam trap ST602, the one-way valve VC603 and the sanita...

Example Embodiment

[0031] Example 2:

[0032] When it is close to the design temperature, the electric heating module is used, and the cooling water flows into the pneumatic valve through the pneumatic angle valve three VPG402 to the pipeline WK-406-”-650 before the heating tank, and then flows into the heating tank WK-T-400 to be heated. The hot water heated by WK-T-400 can flow out from the hot water output pipe WK-404-"-650 of the heating tank, and it can also flow through the pneumatic angle valve IV VPG403 and then through the hot water return pipe WK-405-" -650 flows back to the pneumatic valve to the pipeline WK-406-”-650 before the heating tank. By controlling the number of switches and heating time of the heating tubes in the heating tank WK-T-400, the heating accuracy can be effectively controlled to reach ± Design accuracy of 0.1 degree.

Abstract

The invention discloses a temperature control system for the unfreezing and heat preservation of biological product liquid medicine, and the system comprises a water-bath heating module and an electric heating module, wherein the water-bath heating module comprises an industrial steam heating pipe, a freezing water pipe, a water supplement pipe, and a plate heat exchanger. The industrial steam heating pipe, the freezing water pipe and the water supplement pipe are respectively connected with the plate heat exchanger. The electric heating module comprises a heating tank and an electric heating pipe system, and the electric heating pipe system is connected with the heating tank. The interior of the heating tank is vertically and uniformly provided with a plurality of heating pipes. The water-bath heating module is used for achieving the quick rise of temperature, and improving the temperature response speed. A heat exchanger industrial steam pipe is connected with an industrial steam pneumatic angle valve, thereby achieving a purpose of stopping the industrial steam heating when the industrial steam is nearly heated to designed temperature. The freezing water pipe is used for achieving the cooling of the plate heat exchanger. During the approaching of the designed temperature, the electric heating module can effectively control the precision of temperature rise through controlling the number of heating tube switches in the heating tank and the heating time.

Description

technical field [0001] The invention belongs to the technical field of temperature control. Specifically, the invention relates to a temperature control system applied to the thawing and heat preservation of biological product medicinal liquid. Background technique [0002] With the development of global biotechnology, it is gradually changing from the previous rough biological test conditions to the current high-precision experimental conditions. Biopharmaceuticals are a major event related to human health, and the experimental conditions are more required to be precise and controllable. We know that biological products have special requirements on temperature, requiring fast heating speed, but the temperature difference is controllable. If the temperature is too high, biological products will lose their activity; in addition, the cost of most biological products is relatively high, and the temperature change will be very large. Sensitive, inaccurate temperature control wil...
