Method for treating sludge by using cement kiln, and sludge gasifying cement kiln system
The invention discloses a method for treating sludge by using a cement kiln, and a sludge gasifying cement kiln system. The method for treating sludge by using the cement kiln comprises the following steps: making wet sludge into dry sludge particles, then gasifying the dry sludge particles, sending the fuel gas obtained after gasification into a decomposing furnace, and sending ash obtained after gasification into a crude material system. The sludge gasifying cement kiln system comprises a cement kiln and a decomposing furnace, wherein an inlet of the cement kiln is communicated with an outlet of the decomposing furnace, and a gas inlet of the decomposing furnace is communicated with a gas outlet of a gasifying furnace through a fuel gas pipeline; a feed opening of the gasifying furnace is communicated with a warehouse through a conveying system, and a slag outlet of the gasifying furnace is communicated with the crude material system through a slagging system. According to the method and the sludge gasifying cement kiln system provided by the invention, the treatment scale of sludge can be greatly improved; the difference between the form of solid sludge directly sent to the kiln and the fineness of coal dust as well as a cement raw material is reduced, and the mass and heat transfer effect is increased.
