Embodiment Construction

[0015] As shown in the figure, the solar energy-biomass energy-hydrogen energy coupling complementary power generation method described in the present invention comprises the following steps:

[0016] First, biomass materials such as straw, straw charcoal, corncobs, rice husks, wood chips, cotton stalks, shavings, branches and domestic organic waste are added to the gasifier 1, and the air blown by the air blower is insufficiently combusted. Generate biomass gas containing carbon monoxide, hydrogen, methane and impurities at a temperature of 100-130°C. The generated biomass gas is first passed into the electrostatic decoker 2 to separate the tar, and then pressurized to 0.012 by the pressurizer 3 After -0.018MPa, enter the water mist drop catcher 4 to remove water, and use the dry desulfurization tower 5 to remove the H 2 S off to ≤0.04g / Nm 3 After that, it can enter the biomass gas generator 19 to make it generate electric energy;

[0017] When the sunlight is sufficient, t...

Abstract

The invention discloses a method for generating electricity by coupling and complementing solar energy-biomass energy-hydrogen energy, comprising the following steps: first biomasses are added into a gasifier, and generated biomass syngas enters a generator to generate electric energy after being processed; under the condition of sunniness, the biomass syngas is completely processed and added with hydrogen to be synthesized into methanol gas and water in a methanol synthesis tower, the synthesized methanol is heated in a solar heater and then decomposed into a gas mixture of H2 and CO in a methanol thermal decomposer, and the gas mixture enters the generator to generate the electric energy. The method adopts the biomass energy as a complement of the hydrogen energy and the solar energy during thermal electricity generation and can give full play to the potential of the generator; the biomass energy is used for independently generating electricity without sun, and with sun, the solar energy and the hydrogen energy are used for assisting the biomass energy to generate electricity, thus not only avoiding the sulfide which can not be completely removed from the single biomass energy from corroding gas generators, but also ensuring the stability of network electric power, greatly reducing the electricity generation cost, fully showing the advantage of complementation of the three kinds of energy and realizing round-the-clock operation of the generator.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a solar-biomass-hydrogen coupled complementary power generation method. Background technique [0002] Solar energy and biomass energy are extremely important renewable energy sources. Making full use of solar energy and biomass energy is of great significance to my country's environmental protection, energy conservation and emission reduction, and the establishment of a resource-saving and environment-friendly society. However, the current utilization is very single, either only using solar energy for power generation, drying, heating or air conditioning, etc., or only using biomass energy for power generation, cooking, heating, etc., without organically combining solar energy, biomass energy and hydrogen energy stand up. Contents of the invention [0003] The purpose of the present invention is to provide a power generation method that organically combines the three to make so...
