Problems solved by technology
[0002] In the production process of creatine, ammonia-containing tail gas will be produced. The existing technology is to directly discharge the ammonia-containing tail gas to the outside atmosphere, thereby causing the following problems: one is to affect the environment; the other is to cause waste of resources, because ammonia is an available resource , such as the generation of ammonium sulfate can be used as raw materials

The invention provides a device for recovering tail gas containing ammonia, belonging to the technical field of environmental protection facilities. The device comprises a reaction vessel, a solid-liquid separation mechanism and a filtrate receiver, wherein a stirrer is arranged at the top of the reaction vessel; a discharging hole is formed at the bottom thereof; an ammonia-containing tail gas lead-in pipe used for leading in the ammonia-containing tail gas is connected to the top of the reaction vessel; the solid-liquid separation mechanism is connected with the discharging hole via a first pipe; and the filtrate receiver is used for receiving the filtrate from the solid-liquid separation mechanism, arranged on the side of the solid-liquid separation mechanism and connected with a reaction kettle via a second pipe. The invention has the following advantages that: the ammonia-containing tail gas from the production of creatine is led into the reaction vessel by the ammonia-containing tail gas lead-in pipe, so as to conduct the reaction with the materials added to the reaction vessel, then, the products are led into the solid-liquid separation mechanism via the discharging hole for separation, so as to obtain reusable materials, and the filtrate is led into the reaction vessel via the second pipe, thereby embodying the effects of environmental protection and resource conservation.
Description
technical field [0001] The invention belongs to the technical field of environmental protection facilities, and in particular relates to an ammonia-containing tail gas recovery device. Background technique [0002] In the production process of creatine, ammonia-containing tail gas will be produced. The existing technology is to directly discharge the ammonia-containing tail gas to the outside atmosphere, thus causing the following problems: one is to affect the environment; the other is to cause waste of resources, because ammonia is an available resource , For example, after ammonium sulfate is produced, it can be used as a raw material. With people's increasing awareness of environmental protection, as a production industry of chemical products, it is necessary to recycle ammonia tail gas to protect the environment and save resources. Contents of the invention [0003] The task of the present invention is to provide an ammonia-containing tail gas recovery device capable...
