In addition, when unpurified or incompletely purified dusty gas (such as semi-coke tail gas, calcium carbide furnace tail gas, lime kiln tail gas) exchanges heat with porous bulk materials (such as semi-coke, coke), the dusty gas The dust will enter the pores of the block material, block the pores, pollute the block material, and reduce the quality and pass rate of the block material

Embodiment Construction
[0026] see Figure 1-4 The bin-type dryer shown for drying semi-coke (or coke) with pores with dust-laden gas includes two air inlets 1, two air outlets 2, feeding port 18, and a material outlet. Cuboid airtight container 3, 5 material passages 4 are like 5 walls, vertically pass through the container, there are connecting air inlets and air outlets between the adjacent container inner wall and the material passage and between the adjacent material passages The gas channel 5. There are air holes on the wall of the material channel in the container, and the air holes communicate the gas channel with the inner cavity of the material channel, but the material will not flow out of the material channel through the air holes. The air inlet pipe 11 communicates with the two air inlets 1 . The air outlet pipe 12 communicates with the two air outlets 2 . The two air inlets are located on the same level; the two air outlets are located on the same level.

The invention provides a bin type heat exchanger which is low in material damage rate, small in system resistance, is free of material blind corners, can adapt to dust-contained gas and does not pollute materials and is low in fabricating cost. The bin type heat exchanger comprises a sealed container, wherein the sealed container is provided with an air inlet, an air outlet, a feeding port and a discharging port. The bin type heat exchanger is characterized in that a material channel vertically penetrates through the container, an upper opening of the material channel is connected with the feeding port, a lower opening of the material channel is connected with the discharging port, a gas channel for enabling the air inlet and the air outlet to be communicated is arranged between a container inner wall and the material channel, a discharging control device is arranged on the lower portion of the material channel, and a material channel wall in the container is provided with an air hole.
Description
technical field [0001] This technology relates to warehouse-type heat exchangers (preheaters, dryers, coolers). Heat exchangers for heating, drying or cooling. Background technique [0002] Chinese patent ZL2012201860196 discloses a vertical heat exchanger. When it is working, the gas that exchanges heat with the material passes through the material layer and directly contacts the material for heat exchange. Due to the small gap between the materials, the resistance of the gas passing through the materials is large, so it needs to be equipped with a powerful induced draft fan to suck the gas. In addition, when unpurified or incompletely purified dusty gas (such as semi-coke tail gas, calcium carbide furnace tail gas, lime kiln tail gas) exchanges heat with porous bulk materials (such as semi-coke, coke), the dusty gas The dust will enter the pores of the block material, block the pores, pollute the block material, and reduce the quality and pass rate of the block material...
