Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically a steam cooling device for the production of pharmaceutical intermediates. Background Technology
[0002] The production of pharmaceutical intermediates requires specific temperature and pressure conditions. Using steam to regulate the temperature of equipment enables rapid and uniform heat transfer, which is crucial for ensuring the quality and stability of pharmaceutical intermediates. When it is necessary to reduce the temperature of steam, water spray cooling and pressure reduction cooling are generally used. The former involves spraying cold water into hot steam, utilizing the principle of water evaporation to absorb heat, while the latter involves reducing the steam pressure to lower its temperature. Such cooling methods can ensure the quality of pharmaceutical intermediates. However, these cooling methods result in the loss of some of the steam's heat energy, which cannot be effectively utilized, thus increasing energy consumption. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a steam cooling device for the production of pharmaceutical intermediates, which has the following beneficial effects:
[0016] 1. This utility model uses a vacuum pump to draw hot steam from the inner cavity into a loop pipe. At the same time, a cold water pipe transfers purified water from the water tank to the installation box. The loop pipe contacts and heats the cold water discharged from the cold water pipe. Subsequently, the hot water pipe transfers the heated purified water back to the water tank. Through heat exchange between the loop pipe and the cold water, heat energy is transferred to the cold water, heating it into hot water, which is then transferred back to the water tank. In this way, not only is heat energy recovered, but this recovered heat energy can also be used to power the steam generator, improving the energy utilization efficiency of the entire system.
[0017] 2. In this invention, the steam cooled in the loop pipe will condense into water, which will then flow from the second transmission pipe to the branch pipe. At this time, the water will fall into the cylinder, and the water block can prevent the water from flowing out. One end of the branch pipe is designed to be open to facilitate the discharge of a small amount of steam. The water then falls and passes through the filter screen to filter impurities in the water. Subsequently, the water flows from the connection port into the water tank through the return pipe, realizing the recycling of water resources and reducing water waste. Attached Figure Description

[0039] The working principle of this utility model is as follows: When cooling is required, the vacuum pump 202 is activated, causing the suction pipe 2 to draw hot steam from the inner cavity 102 into the loop pipe 203. At this time, the cold water pipe 403 transfers purified water from the water tank 402 to the installation box 206.

In this way, not only is heat energy recovered, but this recovered heat energy can also be used for other purposes. The steam is supplied to the steam generator 401, which improves the energy efficiency of the entire system. After the heated steam is cooled in the loop pipe 203, it will condense into water. The water will be transmitted from the second transmission pipe 204 to the diversion pipe 3. At this time, the water will fall into the cylinder 303. The water blocking block 302 can prevent the water from flowing out. One end of the diversion pipe 3 is designed to be open so that a small amount of steam can be discharged. The water falls and passes through the filter screen 305 to filter impurities in the water. Then the water flows from the connection port 306 through the return water pipe 405 into the water tank 402, realizing the recycling of water resources and reducing water waste.
