Definitions

  • the present disclosure relates to the technical field of heat exchange, and in particular to a coal pyrolysis process device.
  • coal pyrolysis apparatuses are greatly different from one another, and also have greatly different coal tar yields
  • a coke furnace for making coke and a semi-coke furnace for producing semi-coke have a great difference in furnace type.
  • the coke furnace produces coke with a relatively low amount of volatile matter, has low coal tar yield, but produces a large amount of coal gas
  • the semi-coke furnace produces semi-coke with a higher amount of volatile matter, has relatively high coal tar yield, and produces a slightly lower amount of coal gas.
  • a rotary kiln for coalite tar with high oil yield has become a new favorite in recent years.
  • a Chinese Patent with application number 201010262786.6 and publication number CN101985558 entitled “Coal Decomposing Equipment” discloses a coal decomposing equipment including an airtight kiln body with an coal inlet and an coal outlet, wherein a flame gas pipeline heating facility is set in the kiln body and a channel for impelling and decomposing coal is formed between the flame gas pipeline heating facility and an inner wall of the kiln body; and a coal decomposition gas collecting pipe is provided on the kiln body to communicate with the channel for impelling and decomposing coal.
  • this invention allows a large amount of heat produced by the flame gas pipeline heating facility to be conducted and radiated to the pulverized coal in the channel for impelling and decomposing coal
  • the pulverized coal fully absorbs the heat so as to be heated and decomposed to the fuel gas, tar gas and coal with a higher heat-value in the channel for impelling and decomposing coal.
  • the fuel gas and tar gas communicate with a gas dedust and liquefaction facility outside of the rotary kiln through the coal decomposition gas collecting pipe, and the decomposed fuel gas and tar gas are dedusted, separated, and pressure liquefied.
  • the above-mentioned patent indeed provides relatively high oil yield, and is regarded as an example, but only the maximum tar yield is taken into consideration in this patent, and a relatively large amount of volatile matter in the upgraded coal resulting from such pyrolysis at low temperature and the coal gas amount required by hydrogenation of tar are not taken into consideration.
  • the above-mentioned patent has its limitations in that it either provides a high coal tar yield but low coal gas amount, or provides a high gas yield but low coal tar yield, but cannot satisfy both requirements.
  • an object of the present disclosure is to provide a coal pyrolysis process device in response to the disadvantages of the prior art, which can achieve high-efficient production of both gas and coal tar.
  • a coal pyrolysis process device comprising a primary coal pyrolysis device and a secondary coal pyrolysis device
  • the primary coal pyrolysis device is a coal decomposition apparatus which is in form of a rotary kiln radiant tube and of heating type
  • the primary coal pyrolysis device comprises a primary feed port, a primary discharge port, a primary coal gas outlet, and a heating mechanism in form of a primary radiant tube
  • the secondary coal pyrolysis device comprises a secondary feed port, a secondary discharge port, a secondary coal gas outlet, and a secondary heating mechanism
  • the primary discharge port communicates with the secondary feed port, coal tar is maximally extracted from coal in the primary coal pyrolysis device and then the coal is introduced into the secondary coal pyrolysis device, and the coal continues to be heated up and pyrolyzed at an upper portion of the secondary coal pyrolysis device, so that volatile matter of the upgraded coal upgraded by
  • the secondary coal pyrolysis device is a coal decomposition apparatus which is in form of a rotary kiln radiant tube and of heating type or a coal decomposition apparatus of a shaft kiln heat exchange type.
  • the coal pyrolysis process device further comprises a coal drying device disposed upstream of the primary coal pyrolysis device, and the dried coal is introduced into the primary coal pyrolysis device.
  • the coal pyrolysis process device further comprises a deduster disposed at the primary coal gas outlet and a deduster disposed at the secondary coal gas outlet, and the deduster is a cyclone deduster or gravity deduster or a high temperature membrane filter having a filter element coated with a membrane at its surface.
  • Output of the primary coal gas outlet and Output of the secondary coal gas outlet are mixed together, and firstly pass through the cyclone deduster or gravity deduster and then enter the high temperature membrane filter.
  • the primary coal gas outlet leads to a first membrane filter, and the secondary coal gas outlet leads to a second membrane filter.
  • Output of the primary coal gas outlet passes through a first cyclone deduster or gravity deduster and then enters a first membrane filter, and output of the secondary coal gas outlet passes through a second cyclone deduster or gravity deduster and enters a second membrane filter.
  • the present disclosure has the advantage that when coal is placed in the primary coal pyrolysis device, the tar yield reaches the maximum value, and the primary upgraded coal which still has a relatively high amount of volatile matter is introduced into the secondary coal pyrolysis device in a hot state and continues to be heated up and pyrolyzed, such that upgraded coal with a lower amount of volatile matter is produced, and at the same time more coal gas is additionally produced.
  • the coal gas produced by secondary pyrolysis contains more amount of CO and H2, and CO can be converted into H2 via coal gas, such that sufficient H2 source can be provided for hydrogenation of coal tar, and the cost of hydrogenation of coal tar is effectively reduced.
  • the drying device is added to contribute to reduction of energy consumption in coal pyrolysis; and the filter is added in order to filter out and remove dust from coal gas containing dust and containing tar before separation of oil and gas to ensure the cleanliness of oil and gas so as to establish a good foundation for subsequent treatments of oil and gas.
