Description
Technical field
The utility model belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, is specifically related to a kind of low-rank coal pyrolysis installation.
Background technology
In China, account for more than 55% of coal resource total amount with brown coal and the lower-grade metamorphic bituminous low-rank coal reserves for representative, be mainly distributed in east Inner Mongolia, Yunnan, Xinjiang and Ordos Basin one band.Along with the high coal that goes bad is used fewer and fewer, the Optimum utilization day of low-rank coal shows important.Directly utilize technology or the economic problems of existence relative to low-rank coal, after low-rank coal upgrading, classification sub-prime utilizes should become important directions.Realize industrialized technology as being later than Coal Gasification Technology, low-rank coal upgrading has been endowed the expectation of " with gasification dislocation coal " virtually.
In some Large-scale Coal deep processing project schemes, low order improving quality of coal by pyrolysis is listed in the first step that raw coal transforms.Raw coal first upgrading is divided into solid, liquid, gas three part, solid phase prod enters vapourizing furnace and does gasified raw material or enter boiler and do fuel, in liquid, temperature tar hydrogenation produces clear gusoline, and gas pyrolysis coal gas carries hydrogen for tar production, and residual gas is incorporated to gasification system again and merges utilization.
Publication number is that 101985557B discloses a kind of coal single combustor decomposition device, comprise the sealing rotary kiln body of an arranged transversely, described rotary kiln body comprises an opening for feed, discharge port, it is characterized in that: in described rotary kiln body, a burner is set along kiln body direction, described burner is by gas inlet pipe, stretch out the external air intake duct of rotary kiln, hybrid combustor, lighter for ignition, solid matter radiating pipe forms, described gas inlet pipe, air intake duct be arranged in parallel along the axis direction of rotary kiln body, described hybrid combustor side is communicated with described solid matter radiating pipe, opposite side and described gas inlet pipe, air intake duct is communicated with, described lighter for ignition is arranged on mixed firing indoor, the cavity formed between described burner and rotary kiln body inwall is that coal material advances split tunnel, described coal material advances split tunnel to be communicated with discharge port with described opening for feed, described rotary kiln body upper feeding mouth place end arranges and stretches out the external coal separation combustion gas of rotary kiln, tar gas collection tube, described coal is separated combustion gas, tar gas collection tube and coal material advance split tunnel to be communicated with, the other end is connected with combustion gas dedusting liquid body, described solid matter radiating pipe is communicated with flame gas manifold trunk, described flame gas manifold trunk stretches out outside rotary kiln.
This coal decomposing equipment can solve the resolution problem of low-rank coal particularly fine coal, but the inside heating arrangements of more complicated and distributor gears, easily bring not confirmatory and the normal stability of producing of the Heating temperature in production process, particularly in low-rank coal decomposition course, the temperature controlling and adjustment of the different zones that rotary kiln body is inner in the environment of high temperature is a more insoluble problem.
Summary of the invention
The utility model is for solving Problems existing in above-mentioned technique and method, and proposing one significantly can improve heating arrangements stability and reliability, and can preferably to the low-rank coal pyrolysis installation that Heating temperature controls.
Low-rank coal pyrolysis installation, comprise a rotary kiln body with opening for feed and discharge port, in described rotary kiln body, hot-gas channel is set, the low-rank coal formed between described hot-gas channel and described rotary kiln body inwall advances decomposition channels, described rotary kiln body is arranged the decomposed gas collecting pipe advancing decomposition channels to be communicated with low-rank coal, it is characterized in that: described hot-gas channel comprises front hot-gas channel, rear hot-gas channel, high-temperature gas input/output mechanism on described rotary kiln surface, described high-temperature gas input/output mechanism comprises front high-temperature gas input/output mechanism, rear high-temperature gas input/output mechanism, described front hot-gas channel and described high-temperature gas input/output mechanism connection, described rear high-temperature gas body pipeline and described rear high-temperature gas input/output mechanism connection.
In described rotary kiln body, low-rank coal propulsive mechanism is set.
Described high-temperature gas input/output mechanism is the gas skirt that is tightly connected that rotates in a circumferential direction with described rotary kiln body, and be communicated with described hot-gas channel one end inside described gas skirt, outside is communicated with hot-gas blower/vacuum fan.
Described hot-gas channel is many.
The utility model is by being arranged on high-temperature gas input/output mechanism connection hot-gas channel on described kiln surface, make to pass through high-temperature gas in hot-gas channel, high-temperature gas brings heat to be conducted by duct wall, be radiated in the low-rank coal in low-rank coal propelling decomposition channels, low-rank coal absorbs fully, heat up, decompose, advance in split tunnel in low-rank coal and resolve into combustion gas, tar gas and the higher coal of calorific value, combustion gas is connected by the dedusting liquid body that described decomposed gas collecting pipe and kiln are external with tar gas, by the combustion gas decomposed, tar gas is collected, dedusting, be separated, pressurized liquefied, carry out the extensive utilization of next stage, described hot-gas channel comprises front hot-gas channel, rear hot-gas channel, high-temperature gas input/output mechanism on described rotary kiln surface, described high-temperature gas input/output mechanism comprises front high-temperature gas input/output mechanism, rear high-temperature gas input/output mechanism, described front hot-gas channel and described high-temperature gas input/output mechanism connection, described rear high-temperature gas body pipeline and described rear high-temperature gas input/output mechanism connection, arranging of this structure can make full use of rotary kiln body space, effective increase low-rank coal in kiln body with high-temperature gas contact area, thus enhance productivity greatly.High-temperature gas input/output mechanism itself sets out, and actual is two kinds of high-temperature gas mode of movements, and one is that high-temperature gas enters kiln body from gas skirt, and from hot-gas channel, another brings out; Another kind is just correlated with, and high-temperature gas enters kiln body from hot-gas channel another kind, goes out from gas skirt.
