Technical Field

The invention relates to the technical field of energy conservation of pharmaceutical factories, in particular to a comprehensive utilization system for steam condensation water and exhaust gas of a pharmaceutical factory.

Background

Pharmaceutical plants often use low pressure steam to heat process air conditioning and process equipment, producing large quantities of steam condensate. For a factory area with a built-in boiler, condensed water is often recovered and sent to a boiler room for reuse, but the problem of a large amount of steam emission in the factory area cannot be solved. With the upgrading of urban planning, the boiler is not built by enterprises in a common industrial park, so that the pharmaceutical factory faces the problem that the condensed water cannot be recycled or is difficult to reuse.

The pharmaceutical factory is because process equipment all is complete sets, and steam service pressure is different, and the closed system that adopts the backpressure probably leads to equipment unable to use, consequently, the pharmaceutical factory all adopts open condensate recovery system under the general condition, and the ubiquitous condition of a large amount of gassing exists.

Under the current policy background that energy conservation, emission reduction and safety and environmental protection are advocated vigorously by the state, a series of researches and utilization are carried out on the recovery of steam condensate water in the pharmaceutical engineering industry, a plurality of achievements are obtained, and the steam condensate water is treated mainly by adopting the following modes: the steam condensate water of each using point in the workshop is collected and recycled to a boiler room through a pipeline and is reused as boiler water. Secondly, the recovered steam condensate water is used as a heat source to carry out winter heating design, and the mode is only used in winter of northern pharmaceutical factories. And thirdly, the cooled water enters a reclaimed water pipe network to be used as greening irrigation, water supplement of a fire pool and toilet flushing water. Fourthly, recovering condensed water in large-scale traditional Chinese medicine extraction plants for heat exchange for decoction water in the extraction process, and cooling the condensed water for water supplement by circulating water, but the heat value of flash steam of the condensed water is not recovered.

The recycling problem of the steam condensate can be solved to a certain extent by the aid of the modes, but the problems also exist, for example, municipal steam supply in a garden is increased more and more, and an enterprise does not allow a boiler to be built; heating is not needed in southern projects, and steam condensate water escapes from a sewage pipe network in a plant area to cause steam emission at multiple places in the plant area; the heat exchange cooling water is used as reclaimed water, but hot water of heat exchange has no use point and the like, so that condensed water can not be recovered, heat energy in the condensed water can be well utilized, and the heat value of condensed water evaporation and the condition of steam generation in a plant area are recovered.

At present, the scale of newly-built pharmaceutical projects is more and more huge, the problems are more and more prominent, and the existing steam condensate water recovery mode can not well meet the actual production requirements.
