Abstract

The invention discloses an energy-conservation and environmental-protection sludge combustion device. The sludge combustion device comprises a combustion furnace and a separator; and an intake pipe of the separator communicates to a furnace cavity of the combustion furnace, and the bottom end of the separator communicates to the furnace cavity of the combustion furnace through a return pipe. The device further comprises a sludge conveying pump; a sludge inlet is formed in the top of the return pipe; and a discharge pipe of the sludge conveying pump communicates to the sludge inlet. The combustion device adopts the top feeding, so that sludge is fully and thoroughly combusted in the combustion process. In addition, in the process of the sludge falling by the return pipe, the return pipe achieves a heating and drying effect on the sludge, so that the water content of the sludge is reduced, the dried sludge is fully combusted more easily, the hidden trouble of unqualified environmental protection emission is eliminated, the wind cap blockage problem is solved, and the heat efficiency is effectively improved.

Description

technical field [0001] The invention relates to sludge treatment; in particular, it relates to an energy-saving and environment-friendly sludge burning device. Background technique [0002] In the current circulating fluidized bed boiler sludge combustion adopts bottom feeding. This feeding method tends to cause incomplete combustion of fuel during operation, and it is very easy to coke and block the air cap, resulting in insufficient combustion, greatly reducing thermal efficiency, not conducive to energy saving, and there is a hidden danger of environmental protection failure. Contents of the invention [0003] The purpose of the present invention is to provide a sludge combustion device that uses a top feeding method to fully and completely burn the sludge in order to solve the problems in the prior art in the above-mentioned background technology. [0004] The technical solution adopted by the present invention to solve the technical problem is: an energy-saving and e...
