Abstract

The invention relates to a gas and combustible oil generating device from solid combustible fuel, technology of which is characterized in that the combustible fuel is filled in a gasifier for the reverse incomplete combustion under the hypoxia condition to generate combustible gas and tar. Fuel gas is generated from the generated combustible gas after the dust removing and the high temperature cracking of the second time. Then, the fuel gas enters a main pipeline for the standby application after the temperature lowering, pressurized storing, high pressure liquefaction of the tar, the separation of the tar and highly precise filtering of the tar. The tar in the fuel gas is transformed in three steps of high temperature cracking, high pressure liquefaction and precise filtering. The tar content of the fuel gas entering the main pipeline is low. And the fuel gas belongs to clean fuel gas. Equipments comprises the gasifier, a dust removing high temperature cracking tar device, a temperature lowering device, a compressor, a kindling test air port, a gas storing liquefaction tar tank, a precise filtering tar device, etc. Fuel oil generates from the separated tar after the smelting and the distillation.

Embodiment

Be described further with specific examples in conjunction with the accompanying drawings:

According to the shape of solid-state combustiblesubstance, make vapourizing furnace 1,2 meters of the internal diameters of vapourizing furnace 1, width are 0.6 meter, and insulation layer thickness is 30 centimetres, and outside dimension length is 2: 1 with wide ratio.Inside puzzles with refractory brick, and air outlet and ash output hole are below fire grate.Fire grate is made with the material with refractory properties, and the space between fire grate and the fire grate is 3-5 centimetre.Dust filter 2 is the pyramid type of double headed roller point, make with metal, the air outlet in the above, inlet mouth below, the centre is diameter 1--2 centimetre a dedusting particle, the dedusting particle can carry out pyrolytic gasification again to the tar in the combustion gas under the pyritous situation.Combustion gas enters dust filter 2 by inlet pipe, and ashes is blocked by the dedusting particle and drops in the dust bucket.Cooler 3 is the spiral iron pipes that are placed in the water, and high-temperature fuel gas flows in the pipe the inside, and outside round-robin water works to absorb heat.Gas-holder 6 is a ferrous products, can be high pressure resistant, inlet mouth is 6 upper left of gas-holder, the air outlet is at upper right, gas-holder crouches and puts, discharge of the coke hydraulic fluid port under.During combustion gas process pneumatic plant 4, can be pressurized to 3-5 normal atmosphere, high pressure conditions reaches a high temperature, be stored in the gas-holder 6 after the combustion gas pressurization, the tar in the combustion gas is under the highly compressed effect, and temperature reduces gradually and is atomized into drop, on the gas storage tank skin, slowly flow to the gas-holder bottom, flow out, play the purpose of separating tar through valve pipe.Filtered tar device (7) be iron make, totally enclosed, the inner gas filter of installing, inlet pipe below, escape pipe in the above, the oil pipe that discharges of the coke is in the bottom, tar is emitted from following discontinuity.

According to the figure apparatus shown, with pipeline and ring flange 1,2,3,4,5,6,7 equipment are coupled together in order in order, the air outlet that the air outlet that the air outlet that the air outlet that the air outlet of vapourizing furnace 1 connects inlet mouth, the dust filter 2 of dust filter 2 connects the inlet mouth of cooler 3, cooler 3 connects inlet mouth, the pneumatic plant 4 of pneumatic plant 4 connects the inlet mouth of examination fire tube 5, examination fire tube 5 connects the inlet mouth of gas-holder 6, the air outlet of gas-holder 6 connects coke filter 7 inlet mouths, and coke filter 7 air outlets connect main pipe line.

Solid-state combustiblesubstance is put into vapourizing furnace 1, light from above, start pneumatic plant 4, solid-state combustiblesubstance will burn downwards, generate the pyritous combustion gas, the pyritous combustion gas enters the inlet mouth of fly-ash separator 2 under the effect of pneumatic plant 4, combustion gas is through the dedusting particle high-temperature once more after the cracking, enter cooler 3 from the air outlet outflow and lower the temperature, most of heat is taken away by the water around the cooler in the combustion gas, and combustion gas is flowed out from cooler 3 air outlets, enter pneumatic plant 4, combustion gas enters examination fire tube 5 after pressurizeing through pneumatic plant 4, at examination fire tube 5 places examination fire, when combustion gas can be lighted, open the air intake valve of gas-holder 6 again, begin to collect combustion gas.After operation for some time, open the put-focus fuel tap door of gas-holder 6 and the put-focus fuel tap door of combustion gas coke filter 7, emit tar.

Equipment is in service just to have only an electric motor that drives pneumatic plant 4 in running, and working cost is cheap; Fire grate place temperature height, the fire in a stove before fuel is added is prosperous, and the fuel gases calorific value of generation is just high; Solid-state combustiblesubstance can directly add, and need not pulverize; Dedusting is thorough; Tar filters; But high pressure is supplied gas; Calorific value height, working cost are cheap.The tar of producing is smelted and is become fuel oil.
