Abstract
The invention relates to a heat exchanger for a sleeve kiln. The heat exchanger comprises a fume gas inlet, a fume gas outlet, an air inlet, an air outlet, a pipe box, a pipe pass, a shell pass and a baffle, wherein the fume gas inlet is communicated with the fume gas outlet through the pipe pass; the air inlet is communicated with the high-temperature air outlet through the shell pass; the fume gas inlet is connected with an inlet pipe; a filtering box is arranged in a fume gas inlet pipe; one to ten filtering plates are arranged in the filtering box; and a heat exchange pipe of the pipe pass is a thread sleeve type heat exchange pipe, a double-layer sleeve type heat exchange pipe or a filter pipe type heat exchange pipe. Sticky substances and dust in fume gas are filtered by using the filtering plates, so that the adhesion of the sticky substances and the dust to a pipe wall is prevented, and the blocking of the heat exchange pipe is avoided. By adopting a replaceable heat exchange pipe in which an internal thread sleeve, an internal pipe or a filter pipe is replaced at a fixed period, the normal operation of the heat exchanger and safe production can be ensured. The invention is applicable to heat exchange equipment for a lime kiln and also applicable to the heat exchanger in which the fume gas pre-heats other media for an industrial furnace kiln.
