Energy saving new technology for producing injection water

Abstract

The invention discloses an energy saving new technology for producing injection water, and belongs to the technical field of industry energy saving. The energy saving new technology comprises a distilled water tank, a circulation water pump, a cooler, a steam heater, a compressor, a condenser, a heating power expansion valve and an evaporator. An industry heat pump device is composed of the compressor, the condenser, the heating power expansion valve and the evaporator. In addition, a distilled water inlet pipeline, a steam inlet pipeline, a condensation water pipeline, injection water returnwater supply pipelines, a low-temperature water utilization point, a high-temperature water utilization point and the like are further included. The industry heat pump device utilizes the evaporator for recycling waste heat in cooler circulation cooling water, then the condenser is utilized for preheating low-temperature injection water before the low-temperature injection water enters the heater,a cooling tower and the steam heater are replaced, the running electric charge and the steam consumption are reduced, accordingly, the production cost is reduced, and meanwhile the purposes of energysaving and emission reducing are achieved.

Description

[0001] The invention relates to the technical field of industrial energy saving, in particular to a new energy saving process for producing water for injection. Background technique [0002] In the large-scale infusion and water injection production process of the pharmaceutical industry, there are both low-temperature water points (less than 45°C) and high-temperature water points (greater than 65°C) in the circulation process of water for injection, so the current process flow chart is designed as figure 1 However, there is a defect in this process, that is, in order to meet the requirements of the pharmaceutical specification that the circulating temperature of water for injection should not be less than 65°C and the point of low-temperature water for injection, the water for injection at high temperature (65°C) must be circulated by a cooler first. It can be used after it is lowered to less than 45°C, and the unused low-temperature water for injection needs to be heated to ...

[0002] In the large-scale infusion and water injection production process of the pharmaceutical industry, there are both low-temperature water points (less than 45°C) and high-temperature water points (greater than 65°C) in the circulation process of water for injection, so the current process flow chart is designed as figure 1 However, there is a defect in this process, that is, in order to meet the requirements of the pharmaceutical specification that the circulating temperature of water for injection should not be less than 65°C and the point of low-temperature water for injection, the water for injection at high temperature (65°C) must be circulated by a cooler first. It can be used after it is lowered to less than 45°C, and the unused low-temperature water for injection needs to be heated to more than 65°C by a steam heater before being allowed to return to the distilled water tank, and the cooling is achieved by circulating cooling water and cooling towers; The temperature rise is achieved by steam heating; this process of rising and falling consumes a lot of energy and is unreasonable
