Natural gas heating equipment for coating drying furnace

The invention relates to natural gas heating equipment for a coating drying furnace. The technical problems that an existing drying furnace only consumes natural gas to supply heat continuously, air in the drying furnace cannot flow evenly and smoothly, and high-temperature gas in the drying furnace cannot be recycled are solved. According to the technical scheme, the natural gas heating equipment for the coating drying furnace comprises a furnace body, a heat recovery system and the like; the upper surface of the furnace body is connected with a heat recovery system used for recovering heat in high-temperature gas. The moisture adsorption plate is used for blocking high-temperature gas and slowing down the flow speed to achieve rapid adsorption of water molecules, the high-temperature gas is temporarily reversed at the position of the moisture adsorption plate after being blocked, and energy recovery is achieved in cooperation with the flow guide pipe; the particle capturing plate is used for removing partic
