Water-steam separated steam energy recovery system used for feed production

Abstract

The invention provides a water-steam separated steam energy recovery system used for feed production. The recovery system comprises a conditioner and a feeder. A steam recovery opening is formed in the feeder, and a steam recovery device is arranged. The steam recovery device comprises a sealed outer barrel and a sealed inner barrel. A water seal cavity is formed between the inner barrel and the outer barrel. The inner barrel is in sealed butt joint with the steam recovery opening in the feeder through a steam inlet in the lower end. A backflow hole communicating with the water seal cavity is formed in the upper end face of the inner barrel, and a water seal cover is arranged at the top of the inner barrel and fixed into the outer barrel. A cover opening of the water seal cover stretches into the water seal cavity between the inner barrel and the outer barrel, and a steam recovery channel is formed between the inner cover face of the water seal cover and the inner barrel. An exhaust opening is formed in the top of the outer barrel. After an originally turbid air, steam and dust mixture is washed with water, clean air is exhausted into the atmosphere, heat and dust are reused, energy is recycled, and the field environment is improved.

Description

technical field [0001] The steam recovery and utilization device in the feed production process of the present invention is specifically a water vapor separation steam recovery system used in feed production, which can separate water vapor impurities to recover energy and improve the environment. Background technique [0002] The production of many feeds is obtained by crushing and mixing the raw materials first, and then granulating and cooling after tempering. During the tempering process, steam is required to mature various feed materials and mix them more uniformly. Increase the viscosity of the feed to facilitate granulation. There will be a large amount of secondary steam generated during the conditioning process. In the existing feed production process, there is no special treatment device for the secondary steam generated in the conditioner, and it is usually directly at the feed inlet or other outlets. Connect a pipeline to discharge to the atmosphere or connect a ...

AI Technical Summary

Problems solved by technology

Because the steam discharged by the conditioner still has a lot of heat, direct removal will cause a large amount of energy loss, and because the crushed feed raw materials contain a large amount of organic dust, these dusts are mixed in the steam and will be discharged together with the steam, resulting in Air Pollution

In addition, due to steam leakage due to poor sealing or other reasons during the steam discharge process, there is a phenomenon of steam scurrying in the production site. The scurrying of steam will not only cause energy loss, but also take away material dust , as the steam condenses and sticks to equipment or other surfaces, it will have a serious impact on the site environment
