Problems solved by technology

[0009] 1. It is impossible to realize the maximum comprehensive utilization of low-quality raw materials by using coal, petroleum coke, asphalt and other single raw material gasifiers to produce hydrogen or synthesis gas;
[0010] 2. There is only one single-material single-phase gasification nozzle on the top of the gasifier, and the load of the single nozzle is too large; or when there are four radially opposed nozzles in the cylinder section, the load cannot be increased due to the constraints of radially opposed , the production scale of a single nozzle is relatively small, resulting in

The chilling and washing chamber 4 is arranged at the lower en...

Embodiment 2

[0036] Example 2: A non-catalytic partial oxidation gasifier for inferior raw materials. The inner diameter of the shell of the gasifier is 2600 mm, and the inner diameter of the surface facing the fire is 1800 mm. The gasification reaction chamber 3 communicates with the quenching and washing chamber 4. The gasification reaction chamber 3 is arranged on the upper part of the gasification furnace with a height of 6000 mm, and the quenching and washing chamber 4 is arranged on the lower part of the gasification furnace at a height of 8000 mm. The chamber 3 and the chilling washing chamber 4 share a pressure-bearing cylinder 1, and there are three nozzles arranged on the top of the gasification reaction chamber 3, which are evenly arranged around the center of the top. The angle α is 30°. Three four-channel gasification nozzles 2 are arranged at equal intervals on the furnace roof, wherein oxygen enters the central flow channel and the third flow channel, water-coke slurry enter...

Abstract

The invention relates to a gasification furnace used for preparing synthesis gas, in particular to a multi-jet vertical airflow bed. An oxidative gasification furnace for non-catalytic parts of inferior raw materials comprises that at least a jet (2) on the top part of a gasification reaction chamber (3) which is communicated with a chilling washing chamber (4) and is characterized in that the gasification reaction chamber (3) is arranged on the upper part of the gasification furnace while the chilling washing chamber (4) is arranged at the lower part of the gasification furnace; the gasification reaction chamber (3) and the chilling washing chamber (4) share a pressure bearing cylinder (1). The gasification furnace has the advantages of avoiding the excessive temperature of the upper part of the gasification reaction chamber and also prolonging the service life of a part at a slag export region of the lower part of the gasification reaction chamber.

Description

Technical field: [0001] The invention relates to a gasification furnace for preparing synthesis gas, in particular to a multi-nozzle vertical air-flow bed. Background technique: [0002] With the rapid development of my country's national economy, energy has become the main bottleneck issue for my country to achieve the next strategic goal, which is closely related to national security. In 2004, my country imported more than 100 million tons of crude oil for the first time, and its dependence on foreign countries reached 40%. Imported crude oil is mostly high-sulfur crude oil, which produces a large amount of high-sulfur and high-ash low-quality petroleum coke and low-quality asphalt after deep processing. How to efficiently and cleanly utilize high-sulfur and high-ash low-quality petroleum coke and pitch has become a common problem faced by large petrochemical enterprises. In addition, large oil refining and petrochemical enterprises generally produce a large amount of ca...
