Chemical industry device emptying tail gas process heat-recovering system

Abstract

The invention discloses a waste heat recovery system for the emptying tail gas treatment of a chemical device, which is characterized in that: the invention comprises a combustion chamber, a ring chamber, an ignition chamber, a steam generator and a water preheater orderly connected in series, wherein the ring chamber is connected with an emptying tail gas discharge pipeline for the chemical device, and the combustion chamber is connected with an air blower; the steam generator is provided with a steam drum, the steam drum is connected with the steam generator through one or over two sleeve pipe structures integrated with raising and declining by steam and water. The system has simple and reasonable structure and safe operation, saves energy sources, and realizes the purposes of the heat energy recovery of the chemical device and the reduction of tail gas discharge.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment waste heat recovery, in particular to a waste heat recovery system for chemical plant venting tail gas treatment. Background technique [0002] In the prior art, the tail gas produced by some chemical plants (such as HCN plants) is directly discharged into the atmosphere, which not only pollutes the environment, but also causes energy waste. In response to this situation, some manufacturers have adopted exhaust gas treatment systems or waste heat recovery systems, but these systems have complex structures, cannot effectively recover energy and cause less environmental pollution, and have low operating efficiency, which poses safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is how to provide a waste heat recovery system for exhaust gas treatment of chemical plants. The system has simple and reasonable structure, safe operati...
