Abstract
The invention provides a coal gasification device and a coal gasification process for heating coal water slurry. A heating coiled pipe and a heat exchanger are added in the device, the step of heating the coal water slurry is added, and heat generated by reaction of water gas and oxygen is replaced by heat of black water generated in the gasification process in the traditional method, so discharge of carbon dioxide can be reduced, and energy conservation and environmental friendliness are realized; the yield of available gases (CO and H2) can be increased, the consumption of the oxygen as well as the production cost is reduced, and certain economic benefit is achieved.
Description
Technical field
The invention belongs to coal chemical technology, be specifically related to a kind of coal gasification apparatus and technique of coal water slurry heating.
Background technology
Coal water slurry gasification technique is the comparatively ripe gasifying process of a kind of technology, because in coal water slurry gasification technique, the coal water slurry of normal temperature is directly reacted with the oxygen generating gasification, for carrying out smoothly of guaranteeing to react and ash content melt the slag effect, vapourizing furnace must keep certain furnace temperature.Keep gasifier temperature by consuming water-gas (main effective constituent is CO, H2) with the thermopositive reaction of oxygen in the traditional technology, can consume so more water-gas and and oxygen so that the energy consumption of this technique is higher
Summary of the invention
The coal gasifying process that the purpose of this invention is to provide a kind of coal water slurry heating utilizes the heat in the Heisui River that produces after the gasification that coal water slurry is heated, and improves and advances vapourizing furnace coal water slurry temperature, guaranteeing can to save energy consumption on the same furnace temperature basis, produces economic benefit.
The object of the present invention is achieved like this: a kind of coal gasification apparatus of coal water slurry heating, comprise coal water slurry storage tank and vapourizing furnace, the top of vapourizing furnace is vaporizer, the bottom is the shock chamber, be provided with heat exchange coil in the shock chamber, also be provided with interchanger between coal water slurry storage tank and the shock chamber, the discharge port in the coal water slurry storage tank connects interchanger, heat exchange coil by pipeline successively, is connected at last the opening for feed of vaporizer.
Be provided with water-coal slurry pump between described coal water slurry storage tank and the interchanger.
Be connected to the coal water slurry storage tank by arm between described water-coal slurry pump and the interchanger, and arm is provided with valve.
The thermal source import of described interchanger is connected with the discharge port of shock chamber.
A kind of coal gasifying process of coal water slurry heating, concrete steps are:
1) coal water slurry heating, gasification
Coal water slurry in the coal water slurry storage tank enters interchanger and carries out the heat exchange heating through the water-coal slurry pump pressure-raising, then enters heat exchange coil and again carries out the heat exchange heating, and the coal water slurry after the heating enters vaporizer and gasifies;
2) heat recovery process
The Heisui River that produces after coal water slurry gasifies in vaporizer enters the shock chamber, then enter the thermal source import of interchanger by the discharge port of shock chamber, Heisui River by with the shock chamber in heat exchange coil and the coal water slurry in the interchanger carry out heat exchange, finish the heat recovery in Heisui River.
Coal gasification apparatus and the technique of a kind of coal water slurry heating provided by the invention have following beneficial effect:
1) traditional technology does not have heating steps, and the present invention is keeping in the same furnace temperature situation by having increased heating steps, and can increase the water-gas available gas (is H
2, CO) output, reduce the consumption of oxygen, can enhance productivity, control and reduce production costs, have certain economic benefit.
2) since with when heating used heat come from the heat in Heisui River, the temperature in Heisui River is about 250 ℃, the heat with this heat replacement water-gas and oxygen reaction generation can reduce the discharging of gas consumption and carbonic acid gas, energy-conserving and environment-protective.
