Abstract

The invention discloses a catalytic combustion heating system and belongs to the technical field of catalytic combustion heating and environmental protection. With the system, a heat carrier is heated by heat released by a catalytic combustion reaction. The system comprises a catalytic combustion reaction heating zone, a flow control unit and a flue gas circulating device which is connected with the catalytic combustion reaction heating zone and the flow control unit in a communicating manner; and the catalytic combustion reaction heating zone is connected with the flow control unit in a communicating manner. The invention further relates to a technology for heating with the system. With the system and the technology, industrial waste gas is used as a heat source to provide heat for feed gas and the heat carrier which are required to be preheated, so that the heat utilization rate can be increased, the energy consumption can be reduced, the industrial waste gas is reused, the production cost is reduced, and environmental pollution is reduced. The catalytic combustion temperature is low, the complete reaction is realized, the energy consumption is low, the operation is simple and safe, and the purification efficiency is high. With the system, the land occupied by equipment can be effectively reduced, the cost can be reduced, and resource waste can be reduced.

Description

technical field [0001] The invention belongs to the technical field of catalytic combustion heating and environmental protection, and in particular relates to a catalytic combustion heating system and a heating process. Background technique [0002] At present, the amount of industrial waste gas discharged by industrial enterprises is increasing year by year. Most of these industrial waste gases contain combustible components such as hydrogen, methane, ethane, ethylene, light hydrocarbons above C3, and CO, which have great recovery and utilization value, but the recovery of these The components are technically difficult, the adsorbent needs to be replaced regularly, and the operating cost is high. In addition, the combustible components in the tail gas have not been effectively utilized, resulting in waste of resources. At the same time, chemical companies often need heat carriers such as steam or heat transfer oil at a certain temperature and pressure for specific chemical...
