AUTONOMOUS GENERATOR OF HEAT AND ELECTRICITY FOR RAILWAY TRANSPORT Russian patent published in 2021 - IPC F01K27/00 C01B3/00 

FIELD: hydrogen energy.

SUBSTANCE: invention relates to the field of hydrogen energy, specifically to autonomous heat and electricity generators for railway transport. According to the invention, an autonomous heat and electricity generator (AHEG) for railway transport contains a digital control unit (DCU), a heat extraction device (HED), as well as a sequentially installed chemical hydrogen generator (CHG), a receiver and a hydrogen combustion energy converter (HCEC) into electric energy. The control inputs of the HED, CHG, HCEC are connected to the corresponding control outputs of the DCU 1. The invention also additionally contains a hydrogen mixture quality regulator (HMQR) installed between the receiver and the HCEC, which includes a series-connected internal combustion engine (ICE) and a drive electric current generator (DECG), CHG contains a collector with a block of replaceable cartridges (BRC) filled with a chemical substance, entering into an exothermic reaction with water with the release of heat and hydrogen. In addition, the BRC includes at least one removable starting cartridge (RSC) and at least one removable working cartridge (RWC). Each RSC and RWC is designed to be installed in the heat exchange recesses of the water jacket of the heat exchanger and to be connected via a hydrogen outlet through a manifold with a water seal of the receiver, the hydrogen cavity of which is connected through a pneumatic pressure sensor to the signal input of the DCU and directly to the hydrogen input of the HMQR containing a mixer, the first the inlet of which is connected through the hydrogen dispenser to the hydrogen outlet of the receiver, the second inlet of the mixer through a non-combustible gas meter (NCG), the compressor and air intake - with the outlet of the exhaust pipe of the internal combustion engine, and the outlet of the mixer - with the gas inlet of the internal combustion engine, the power take-off shaft of which is kinematically connected to the rotor rotation shaft of the DECG, the stator windings of which are directly connected to the output terminals and through a current rectifier and a capacitive electricity storage with a power supply input of the DCU. Wherein the chemical filling of the RSC contains a mixture of aluminum powder (Al) and caustic soda NaOH, and the RWC contains powder or aluminum shavings, on one of the end sides of the cartridges there is a hydrogen outlet (H2) with an external thread corresponding to the internal thread of the collector connecting window, and on the other end side of the cartridges there is a check valve connected through the water inlet through a quick-release coupling, through a water meter, a flexible hose and a connecting pipe with the cavity of the water jacket of the heat exchanger equipped with cold water inlet and hot water outlet pipes for an external heating system and/or hot water supply.

EFFECT: improvement of autonomous heat and electricity generators for railway transport.
