Problems solved by technology
[0002] Calcium oxide needs to be calcined in the combustion furnace during the processing process, but the combustion furnace will discharge high-temperature gas during the calcination process, and there are certain impurities and odors in the gas, which are generally discharged through a higher exhaust pipe. High-temperature gas is discharged into the air, but this will have a certain impact on the surrounding air environment, and waste the heat in the gas, and impurities and odors will also float in the air, which will affect the residents living around the factory or those working in the factory. The staff caused certain adverse effects, so there is an urgent need for a waste heat recovery and utilization system for calcium oxide production

The invention discloses a waste heat recycling system for calcium oxide production, which belongs to the technical field of calcium oxide, and comprises a combustion furnace, a first filter screen, a cooling box, a coiled pipe, a filter box and a spraying box, the combustion furnace is provided with an air outlet pipe, and the other end of the air outlet pipe is arranged above the cooling box; and the other end of the air outlet pipe is fixedly connected with the top end of the coiled pipe, the bottom end of the coiled pipe communicates with a first connecting pipe, the first connecting pipe is installed below the cooling box, the other end of the first connecting pipe is installed on the left side of the spraying box, a first filter screen is arranged on the inner wall of the spraying box, and a first discharging pipe is arranged on the right side of the spraying box. Due to the arrangement of the cooling box, the coiled pipe, the spraying box, the spray head, a cold water inlet pipe, a hot water outlet pipe and the filter screen, the problem that discharge of high-temperature gas affects residents living around a factory or workers working in the factory to cause adverse effects is solved, and the air quality is improved.
Description
technical field [0001] The invention belongs to the technical field of calcium oxide, in particular to a waste heat recovery and utilization system for calcium oxide production. Background technique [0002] Calcium oxide needs to be calcined in the combustion furnace during the processing process, but the combustion furnace will discharge high-temperature gas during the calcination process, and there are certain impurities and odors in the gas, which are generally discharged through a higher exhaust pipe. High-temperature gas is discharged into the air, but this will have a certain impact on the surrounding air environment, and waste the heat in the gas, and impurities and odors will also float in the air, which will affect the residents living around the factory or those working in the factory. The staff caused certain adverse effects, thus urgently needing a waste heat recovery and utilization system for calcium oxide production. Contents of the invention [0003] The ...
