Problems solved by technology

However, when the plasma spray gun is used alone to pyrolyze water to produce hydrogen, the hydrogen and oxygen cannot be separated in time and the reverse reaction will easily occur, resulting in low hydrogen yield, and there is a problem of waste heat recovery, resulting in energy loss, so it is not economical

Abstract

The invention discloses a device for producing hydrogen from water through pyrolysis by adopting plasma and co-producing gas through coal gasification, which relates to plasma coal gasifier equipment. The device is composed of a gasifier, a plasma torch, a helical pusher and a bunker, wherein inner spaces of an anti-scorching water jacket and a refractory layer a constitute a gasifier hearth, a synthetic gas channel is led out above the wall in the front of the gasifier hearth, a synthetic gas outlet is arranged on the top end of the synthetic gas channel, a slag discharging port is arranged below the wall at the rear end of the gasifier hearth, the slag discharging port is connected to a slag basin via a water seal, the plasma torch is arranged at the rear end of the gasifier hearth, a nozzle of the plasma torch faces towards the interior of the gasifier hearth, the helical pusher is arranged in front of the gasifier hearth, and a discharging end of the helical pusher stretches into the gasifier hearth. The device realizes that hydrogen is produced from water through pyrolysis by adopting plasma and gas is co-produced by coal gasification in a complementary manner in order to overcome the defects in single technique, thereby achieving the purposes of improving the quality of synthetic gas, saving the loss of coal and reducing the emission of greenhouse gases.

Description

technical field [0001] The invention relates to coal gasification equipment, in particular to a plasma coal gasification furnace equipment. Background technique [0002] At present, in the conventional coal gasification device, water vapor + air or water vapor + oxygen are directly sent into the gasification furnace as the gasification agent, so that the water vapor and coal undergo a gas-forming reaction to generate synthesis gas. The reaction is an endothermic reaction, which needs to be produced by The oxidation reaction between air or oxygen and carbon provides heat for it. This gasification method will increase the consumption of coal resources. Lots of greenhouse gases. [0003] Existing studies on hydrogen production from thermochemical water splitting reveal that the thermal decomposition of pure water avoids the conversion process of "heat→work" and directly converts heat energy into hydrogen energy. The theoretical conversion efficiency is very high, but this reac...
