Embodiment Construction
[0012] Furnace body 20 and most of its structure are formed by steel coils and welded with various shapes of profiles, small components and pipe fittings, and are equipped with water seal seat 8, water seal cover 6, fire cap 14, upper and lower partitions 23, 24 and other iron castings. The measuring rod 7 adopts steel bar welding. Body of furnace 20 should be placed on the suitable position of room or other flat open spaces, leave enough space around, be convenient to connect other pipelines and operate. Install a valve at the 12 place of the drain pipe, install a 10-20W fan at the inlet of the air inlet pipe 15, connect a smoke exhaust pipe at the 5 place of the exhaust gas outlet of the chimney, and install a valve at the 9 place of the exhaust pipe to connect to the pipe, stove or other gas Tool.
[0013] Take off the water seal cover 6 and the measuring rod 7, after loading the fuel, put the lower end of the measuring rod 7 on the top of the fuel, the water seal cover 6...

The invention relates to a downdraft negative pressure straw gasifier which aims at recycling pyrolysis tar oil, purifying combustible gas and simplifying the operation; the downdraft negative pressure straw gasifier comprises a furnace body, an upper clapboard, a lower clapboard, a blast pipe, an igniter capsule, a material measuring rod, a water seal base, a water seal cover, a gas stove gas-distribution cabinet, a closed interlayer, a tar discharging screw rod, a gas seal cover and a screw rod; the closed interlayer is a ring-shaped barrel shape and is circumferentially arranged at the upper half part of an inner furnace chamber of the furnace body along the furnace body; the upper clapboard is arranged at the upper part in the closed interlayer, a square tube is arranged on the inner wall of the closed interlayer, and the square tube is opened top and bottom; a gas collecting hole is arranged on the inner wall of the closed interlayer, and the middle section of the square tube is communicated with the closed interlayer by the gas collecting hole; a vertical clapboard is arranged in the closed interlayer and is vertical to the inner wall in the closed interlayer, so as to separate the ring-shaped inner cavity; the vertical clapboard is arranged on a short segmental arc between the exhaust pipe and the gas collecting hole; the tar discharging screw rod is a screw rod with a conical body at front end and is arranged on the furnace body, and the position of the tar discharging screw rod corresponds to the tar discharging hole on the inner wall of the closed interlayer.
Description
technical field [0001] The invention relates to an improvement of a straw gasification furnace. Background technique [0002] Jugan gasifiers have been gradually popularized and applied in rural areas, but the existing gasifiers generally have problems such as tar difficult to remove, peculiar smell, smoke when feeding, unstable gas, and short gas production time. And the operation is more complicated, and common people are difficult for grasping. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a downdraft negative pressure straw gasifier which can fully recover cracked tar, purify combustible gas and simplify practical operation. [0004] The invention includes furnace body, upper and lower partitions, closed interlayer, coke discharge screw, air inlet pipe and fire cap, material measuring rod, gas sealing cover and screw, water sealing seat and water sealing cover, gas s...
