The invention belongs to the field of efficient and clean utilization of coke-oven gas, and particularly relates to a process for preparing liquefied natural gas from coke-oven gas with a transformation methanation-free circulation loop. The process comprises the following steps: coke-oven gas is subjected to compression purification, hydrodesulfurization and wide temperature shift, then enters a methanation unit and passes through a plurality of methanation reactors connected in series, all carbon-containing compounds in shift gas are converted into methane, and methane-rich gas is subjected to cryogenic separation to obtain an LNG product. The process is simple, easy to operate, free of methanation recycle gas, good in process reliability, low in comprehensive energy consumption and large in operation flexibility, and the system is suitable for large-scale methanation production.

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 utility model discloses tail gas treatment equipment for drying in artificial board production. The tail gas treatment equipment comprises a box body, an adjustable photolysis catalytic oxidation mechanism and a leak hole box, an air outlet pipeline is arranged at an air outlet in the right end of the box body, an air inlet pipeline is arranged at an air inlet in the left end of the box body, and traction hanging lugs are arranged at the upper ends of the front end and the rear end of the box body; the adjustable photolysis catalytic oxidation mechanism is arranged at the left end of the box body; the leak hole box is inserted into an insertion opening in the right side of the interior of the box body, activated carbon particles are evenly distributed in the leak hole box, first air holes are evenly distributed in the left wall of the insertion opening, second air holes are evenly distributed in the right wall of the insertion opening, the first air holes are all communicated with the interior of the box body, and the second air holes are all communicated with the interior of the air outlet pipeline; the tail gas treatment equipment for drying in artificial board production can treat a large amount of industrial tail gas with the characteristics of large gas amount, high dust content, high temperature, low organic matter concentration and the like.

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.
