The invention provides a bypass air discharging boiler for cement kiln waste heat recovery and power generation, and is applied to the technical field of cement kiln waste heat recycling devices. A boiler body (1) of the air discharging boiler is communicated with the rotary kiln tail (3) for conveying high temperature flue gas generated by a cement kiln, an evaporator (4) and a superheater unit (5) are arranged in the boiler body (1), one end of a steam pocket (2) is communicated with a water source (6), the other end of the steam pocket (2) is communicated with the evaporator (4) in the boiler body (1), the evaporator (4) is communicated with a steam-water separation component (7) in the steam pocket (2), the steam-water separation component (7) is communicated with the superheater unit (5), and the superheater unit (5) is communicated with a steam power generation turbine (8). The bypass air discharging boiler is simple in structure, waste heat generated by bypass air discharging can be effectively recovered, and the high temperature flue gas can be effectively cooled; meanwhile, heat of the high temperature flue gas is sufficiently used, and effective utilization of energy resources is improved.
Description
technical field [0001] The invention belongs to the technical field of cement kiln waste heat recovery and utilization equipment, and more specifically relates to a bypass ventilation boiler for cement kiln waste heat recovery and power generation. Background technique [0002] The alkali content in the raw materials of the cement clinker production line exceeds the standard. In terms of process operation, it is necessary to release part of the high-concentration chloride ion dust from the cement kiln system by bypass to reduce the chloride ion concentration and reduce the system skinning phenomenon. In order to fully recover and utilize the waste heat in the bypass ventilation at the kiln tail of the cement rotary kiln, a bypass ventilation boiler is installed at the kiln tail. The bypass releases about 30% of the air volume and high-temperature air with a temperature of about 970°C. Due to the high temperature of the flue air, it is easy to cause the air intake and pipes t...
