2results about How to "Big air" patented technology

The utility model discloses a high efficiency's fierce fire staggered floor combustion system of upper air inlet, include: furnace head subassembly, furnace base, blast box, air blower and fierce fire air outlet structure, blast box and air blower set up in the below of range panel, the blast outlet of fierce fire air outlet structure is located the above of range panel, towards the injection port of injection channel, blast box is equipped with the blast connecting port of connecting fierce fire air outlet structure, and air blower can send air through blast box to the blast outlet of fierce fire air outlet structure, the utility model discloses, break through upper air inlet space limit, realize efficient blast, the core innovation is in the ingenious adoption " blast source lower -positioned, air -supply path up -going, air -out point upper -positioned " split type design. Through special fierce fire air outlet structure, air is accurately delivered to the injection channel injection port near the above of range panel, realizes the core function of forced air supply. This design perfectly adapts the structural characteristics of all upper -positioned of upper air inlet burner injection system.

The application relates to the technical field of gas flow bed coal gasification production processes, and provides a crude coal gas pre-washing device which comprises a water washing tower, a crude coal gas pipe is arranged in the middle of the water washing tower, an extension pipe is connected to the crude coal gas pipe in the water washing tower, the extension pipe extends to below the liquid level, a plurality of gas distribution holes are arranged on the extension pipe, and the gas distribution holes are located below the liquid level. The crude coal gas is introduced into black water through the extension pipe for washing, meanwhile, the crude coal gas is divided into a plurality of small gas flows through the gas distribution holes, so that the crude coal gas is fully mixed with the black water, the washing effect of the crude coal gas is ensured, the water washing tower tray load is reduced, the tower tray is prevented from being scaled and the synthetic gas is prevented from being mixed with ash and water, and the service life is prolonged. Meanwhile, the main road gas volume of the extension pipe can be reduced, the pump cavitation caused by the bottom black water pump suction bubbles is reduced, the pump outlet flow low interlock system shutdown and other abnormal accidents are avoided. The scheme has few structures, does not change the existing water washing tower, has low cost and good safety effect.
