Eddy flow abrasion-resistant coal dust gasification furnace

Abstract

The invention discloses an eddy flow abrasion-resistant coal dust gasification furnace, which belongs to the field of coal gasification. The eddy flow abrasion-resistant coal dust gasification furnacecomprises a furnace body, a flange is arranged at an upper port of the furnace body, the furnace body comprises an upper chamber and a lower chamber which are mutually isolated, a water screen connected with a flange is arranged in the upper chamber, a sealed combustion chamber is enclosed by the water screen, a burner assembly communicated with the combustion chamber is arranged at the flange, acoal dust conveyer pipe used for sending the coal dust to the burner assembly is arranged at the flange, a downcomer communicated with the lower chamber is arranged at the lower end of the combustionchamber , a process gas outlet is arranged at the upper part of the lower chamber, and a waste material processing apparatus is arranged at the bottom of the lower chamber. The eddy flow abrasion-resistant coal dust gasification furnace reduces the erosion of coal dust to a coal dust intervention device and attachment of the coal dust in the coal dust intervention device, so that the loss of thecoal dust intervention device is reduced, obstruction of coal dust is avoided, gas efficiency and quality of the gasification furnace are guaranteed, the service life of the gasification furnace is prolonged, and the reliability of the gasification furnace for long-time operation can be increased. The gasification furnace is worth of popularization and usage.

Description

technical field [0001] The invention belongs to the technical field of coal gasification, and in particular relates to a swirling anti-wear pulverized coal gasifier. Background technique [0002] In today's society where resources are abundant but resource reserves are relatively scarce, if human beings want to develop longer, they need to take a long-term view, improve energy utilization, reduce environmental pollution, and achieve sustainable development. At present, coal is one of the main fossil energy sources in China and occupies a very important position in my country's energy production structure. In the current energy consumption structure at all levels, coal consumption accounts for 2 / 3 of the total consumption. The shortage of petroleum resources in the world has made the development trend of coal chemical industry replacing petrochemical industry increasingly rapid. The modern new coal chemical industry mainly produces clean energy and products that can replace ...

Problems solved by technology

[0003] In the above gasifiers, the method of introducing pulverized coal and gasifying the pulverized coal is used. The pulverized coal scours the pipeline in the gasifier seriously, causing damage to the internal structure of the gasifier; at the same time, the pulverized coal is easy to Adhering to the surface of the gasifier, long-term use is likely to cause blockage, affecting the efficiency and quality of the gasifier; at the same time, the traditional gasifier burns scattered, cannot fully combine with oxygen and steam, and the combustion is insufficient, resulting in heat dispersion. Low gas production and low coal utilization
