Definitions

  • the invention relates to a transverse flow charcoal gasifier comprising a generator, a cooler and a purifier, the generator operating with horizontal reverse draft.
  • a major drawback of the use of gasifiers on motor vehicles is their size. Indeed, the assembly of the different elements of the gasifier and in particular of the generator and the purifier requires a relatively large volume which is taken, in the case of vans or trucks, from the useful volume reserved for loading and, for vehicles tourist, on the trunk.
  • One solution in the latter case is to mount the gas generator on a trailer which is then coupled to the vehicle.
  • the gasifier according to the invention comes in a form compact, can be easily attached to the front of a vehicle and combines a number of improvements to the cooling and gas purification system. It includes, among other things, a gas cleaning device of small size and high efficiency based on the principle of wet purification by injection of water, which until now was considered inapplicable to mobile gasifiers.
  • the single figure represents a schematic view of a gasifier according to the invention.
  • the gasifier shown comprises in known manner a generator 1, a cooler 2 and a purifier 3.
  • the generator 1 comprises a hopper 4 receiving the fuel which feeds the hearth 5.
  • the hopper can be isolated from the hearth by a sliding shutter plate 6.
  • the hearth is provided with a nozzle 7, optionally cooled by a circulation of water , by which the air necessary for combustion is sucked in, and a vertical hearth grate 8.
  • This grate is fixed to the ashtray 9 which extends on either side of it.
  • the part of the ashtray not located under the hearth makes it possible to complete the reduction of entrained dust and ensures the collection of ash falling from the dust removal capacity 10, the sliding closure plate 6 not occupying the entire width and forming a baffle by two lateral intervals.
  • the cooler 2 is disposed between the outlet of the dust removal capacity 10 and the condenser 11 and is in the form of a tube, housed in the hopper 4 and surrounded by the fuel charge to which it gives up its cha their.
  • the tube opens into a compartment 12, provided against the wall 13 of the hopper or formed in said wall and provided at its upper end with an access plug 14.
  • a spray device 15 is provided in the compartment 12 and cooperates cooling the gas leaving the tube 2.
  • the condensation water or the condensates flow over the entire surface of the filter material 16 contained in the purifier 3.
  • the filter material consists of granules porous maintained by a retaining grid 17 surmounting the gas outlet 18 and the condensate pan 19.
  • a cleaning hatch 20 is provided in the wall of the condensate pan and gives access to a diaphragm pump 21 which provides via the tube 22 feeding the spraying device 15 by recycling the condensates, previously separated from their solid charge by the filtering material 16.
  • the diaphragm pump is preferably mounted integral with the hatch 20 and is driven by variations in internal pressure resulting from the operation of the engine.
  • the draft of the gasifier is of the transverse inverted type, that is to say that a vacuum cleaner, not shown, disposed at the outlet 18 of the purified gas, creates a current in the direction nozzle 7, hearth 5, hearth grate 8, therefore transversely with respect to the charcoal supply, the gas formed does not pass through the mass of the fuel before purification.
  • the condenser 11 makes a first gas-condensate separation using the latter to increase the filtration efficiency and the retention capacity of the purifier 3.
  • the elements 110, 111, 112 of the condenser are inclined and define a cross-sectional area. approximately triangular vertical with an apex corresponding to the gas outlet from compartment 12. They make it possible to distribute the condensates as uniformly as possible on the surface of the filtering material 16.
  • a second gas-condensate separation continues in the filter mass, the calories of which are removed by the descent of the condensates in the tank 19.
  • the cooling of the nozzle is possibly ensured by thermosyphon.
  • the jacket or the cooling channels is (or are) supplied with water by two tubes 23, 23A opening into a water tank 24 provided with a plug 25.
  • the cooling device can also act as a steam generator to introduce at the inlet of the nozzle 7 a quantity of steam sufficient to ensure enrichment of the gas with hydrogen without disturbing the progress of the gasifier.
  • the tank is hermetically sealed and an injection tube 26 communicates the free volume located above the water level with the inlet of the nozzle.
  • the addition of water to the inlet of a gasifier has the effect of maintaining the temperatures of hearth below the dangerous threshold; this effect is all the more important as the quantity of water injected is greater. Self-regulation is thus obtained by more or less significant production of steam.
  • the maintenance of the gasifier according to the invention is as follows: periodically decend the hearth 1 by isolating it from the hopper 4 by maneuvering the closure plate 6.
  • the ashtray 9 is removed, including claws 27, provided on the part located below the hearth, allow the extraction of mints or slag.
  • Periodic cleaning of the separator part is carried out by simple washing with running water, from the upper part after removal of the plug 14, and opening of the doors 20 and possibly 28.
