[0019] Example 1: see figure 1 with figure 2 , A biomass two-stage entrained-bed gasification device, comprising a furnace shell, a gasification chamber and a synthesis gas cooling chamber are arranged in the furnace shell, and the gasification chamber is divided into an upper gasification chamber and a lower gasification chamber. The top of the upper gasification chamber is provided with an overhead syngas outlet, the lower gasification chamber is connected to the upper gasification chamber through the middle throat section, and the axes of the upper and lower gasification chambers intersect vertically, and the synthesis gas The gas cooling chamber is arranged below the gasification chamber in the lower section, the conical slag opening of the gasification chamber is arranged at the bottom of the gasification chamber in the lower section, the bottom of the furnace shell is provided with a slag pool, and the bottom of the slag pool is provided with a slag pool slag discharge po...

Embodiment 2

[0024] Example 2: The figure is not drawn. The structure of Example 2 is basically the same as that of Example 1. The similarities are not repeated. The difference is that the axis of the side process burner and the radial direction of the upper gasification chamber The included angle α is 5°, and the included angle β between the side process burner and the axis of the upper gasification chamber is 5.5°.

Embodiment 3

[0025] Example 3: The figure is not drawn. The structure of Example 3 is basically the same as that of Example 1. The similarities are not repeated. The difference is that the axis of the side process burner and the radial direction of the upper gasification chamber The included angle α is 7.5°, and the included angle β between the side process burner and the axis of the upper gasification chamber is 9.5°.

Abstract

The invention relates to a two-section type entrained-flow bed gasification device for biomasses and a gasification method. The two-section type entrained-flow bed gasification device comprises a furnace shell, wherein the furnace shell is internally provided with a gasification chamber and a synthesis gas cooling chamber; the gasification chamber is divided into an upper-section gasification chamber and a lower-section gasification chamber; a synthesis gas outlet is arranged at the top of the upper-section gasification chamber; the axes of the upper-section gasification chamber and the lower-section gasification chamber are vertically crossed; the synthesis gas cooling chamber is arranged below the lower-section gasification chamber; a dreg tank is arranged at the bottom of the furnace shell; a dreg discharging opening of the dreg tank is arranged at the bottom of the dreg tank; at least one layer of a side face process nozzle chamber is arranged at the periphery of the upper-section gasification chamber; at least two side face process nozzles are symmetrically arranged in the side face process nozzle chamber; oppositely-arranged type process nozzle chambers are coaxially arranged on the two sides of the lower-section gasification chamber; two oppositely-arranged type process nozzles are coaxially arranged on the oppositely-arranged type process nozzle chambers; at least two secondary oxygen feeding spray gun chambers are arranged between the side face process nozzle chamber and the lower-section gasification chamber; the secondary oxygen feeding spray gun chambers are internally provided with secondary oxygen feeding spray guns. The two-section type entrained-flow bed gasification device for the biomasses can be used for gasifying pure oxygen fuel gas; the gas yield is increased by one time when being compared with that of an interval type gasification process.

Description

Technical field [0001] The invention relates to a biomass two-stage entrained bed gasification device and a gasification method. Background technique [0002] With normal fuel combustion, air is used as a combustion aid. The air contains 21% oxygen and 79% nitrogen. During combustion, only oxygen plays a role. Nitrogen is only used as a diluent except for special purposes. A large amount of nitrogen absorbs the combustion reaction heat in vain. If it is not recycled, it will not only increase the greenhouse effect, but also easily produce NO during the reaction process. x Gas further causes environmental pollution. From the 1960s, people bar pure oxygen as a combustion-supporting agent recommended to the industry, and in the past 10 years, starting from the urgent need to save energy and reduce pollution emissions, a biomass two-stage entrained bed gas has been more needed. 化装置。 Chemical devices. Summary of the invention [0003] The purpose of the present invention is to provide...
