Description
Technical field
The present invention relates to a kind of rotating filler air lock door and use the negative pressure coal pyrolysis stove of this gate, belonging to coal deep-processing machine equipment technical field.
Background technology
In the explored coal reserves of China, the coal of about 55% belongs to the low-order coal that degree of coalification is low, such as brown coal and ub-bituminous coal.Although these low-order coal are unfavorable for directly burning, but based on the feature that its volatile matter content is high and reactivity is strong, it is particularly suitable for carrying out gasification synthesis processing.Gasification synthesis processing technique can be divided into high temperature pyrolysis and two processes of char gasification, and the high temperature pyrolysis of its mid-early stage has important impact for follow-up During Char Gasification.Because the change of high temperature pyrolysis condition will affect physico-chemical property and the structure of coal tar, and then affect reaction rate and the product composition etc. of char gasification, so low-order coal gasification synthesis processing its high temperature pyrolysis process is studied first.The present invention is the innovation achievement drawn during Inner Mongolia Autonomous Region plan of science and technology Funded Projects " research of Erdos area Coal Chemical Industry coal for gasification coal adaptability " is carried out, the rotating filler air lock door of design and use the negative pressure coal pyrolysis stove of this gate to be mainly used in the high temperature pyrolysis course of processing of low-order coal.
Pressure has had a large amount of report for the research of coal pyrolysis behavior.In general, improve the universal affecting laws of pressure and be suppression tar generation and reduce total fugitive constituent yield, and aggravate the secondary response of volatile matter, increase gas yield.It is generally acknowledged that volatile matter presoma is attributed to bulk diffusion that concentration difference causes and the forced convertion that barometric gradient causes at the transport mechanics within coal particle, the diffusion reducing volatile matter presoma is occurred by the pressure increasing ambient gas, thus be passed to hole and reduce to the speed of gas phase diffusion around, the increase of the external gas pressure simultaneously will reduce barometric gradient.The time lengthening meaning volatile matter presoma in granule internal stops that slows down transported within granule, thus produce a large amount of light gas by secondary pyrolytic reaction.
In prior art, coal pyrolysis is carried out at pressure-fired or direct draught, there is tar yield low, and raw coke oven gas leaks, and pollutes the problems such as environment.Based on the pressure influencing mechanism to coal pyrolysis process, negative pressure pyrolytic process can be used, be possible not only to improve tar yield, reduce the diffusional resistance of volatile matter, also can effectively reduce the second pyrolysis of volatile matter simultaneously.At Chinese invention patent " a kind of method of producing high-yield tar by pyrolyzing coal ", (number of patent application is 200910260075.2, publication date is on June 29th, 2011) in propose a kind of use negative pressure pyrolysis principle fecund tar pyrolytic process of coal, the generation of secondary response during minimizing pyrolysis of coal, improve tar yield, the cleaning achieving pyrolysis of coal produces, and solve low-disintegration coal can not the problem of Appropriate application simultaneously.(number of patent application: 2014102611315 in the Chinese invention patent application that patent name is " a kind of improve hydrocarbon yield and the device of high efficiente callback oil gas and technique ", publication date: 2014.09.17), propose a kind of coal pyrolysis processing technique using negative pressure pyrolysis principle and device, including the pyrolysis oven being sequentially connected with, hot precipitator, high efficiency particulate air filter, high-temperature blower and gas recovery system for oil, the high temperature raw coke oven gas that pyrolysis oven produces is after hot precipitator rough dusting and high efficiency particulate air filter degree of depth dedusting, the dedusting gas obtained is sent into gas recovery system for oil through high-temperature blower and is reclaimed oil gas, pyrolytic process completes under the negative pressure state provided by high-temperature blower, high-temperature blower provides power source for gas recovery system for oil, petroleum vapor recovery process completes under barotropic state.But regrettably, the structure of negative pressure pyrolysis oven, especially its pan feeding and discharge are that the applicant of problem above-mentioned two patent how realizing sealing and working continuously does not make introduction.
