Coal supporting device of coal gas generation furnace

Abstract

The present invention relates to a coal supporting device of a coal feeding system of a coal gas generation furnace. The device comprises an upper coal supporting hopper, a lower coal supporting hopper, a cover plate device, material cups, and material cup lifting and placing mechanisms. A material feeding port of the upper coal supporting hopper is fitted with the cover plate device. A material outlet of the upper coal supporting hopper is provided with a sealing seat, wherein the lower end of the sealing seat extends into a material feeding port of the lower coal supporting hopper, and the sealing seat is fixedly connected with the lower coal supporting hopper. A material outlet of the lower coal supporting hopper is provided with a sealing seat. The upper coal supporting hopper and the lower coal supporting hopper are provided with the material cups and the material cup lifting and placing mechanisms, wherein the material cups are matched with the lower end opening of the sealing seat, and is driven to lift through the material cup lifting and placing mechanisms to close the opening of the sealing seat. According to the present invention, the structure of the device is artful and reasonable; the upper coal supporting hopper and the lower coal supporting hopper are arranged into the series connection structure, such that the solid fuel can be stored hierarchically, and the fuel adding time can be flexibly controlled; the upper coal supporting hopper and the lower coal supporting hopper are combined to use, such that the leakage of the coal gas in the furnace can be effectively prevented during the solid fuel adding, the energy loss can be avoided, and the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to a gas generator, in particular to a coal bearing device in a coal feeding system of the gas generator. Background technique [0002] At present, the fuels used in industrial production and daily life mainly include solid fuels, liquid fuels and gaseous fuels. From the perspective of international development trends, gaseous fuels have the most extensive application range and application prospects. [0003] Gaseous fuel is generally called coal gas, which can be divided into two categories according to its production methods: natural gas and man-made gas. Among natural gas, there are mainly gas well gas, mine gas, petroleum-associated gas and natural biogas extracted from the ground through drilling. . Among the artificial gas, there are mainly coke gas, producer gas and liquefied petroleum gas. [0004] Producer gas is a product of the thermal heating process of solid fuel (coal or coke) through gasification, that is, oxygen ...

AI Technical Summary

Problems solved by technology

The disadvantages of this coal bearing device are: 1. When the material cup is opened, the gas in the furnace will leak upwards from the coal bearing device. On the one hand, it will cause waste of energy, and on the other hand, it will also cause environmental pollution. Harmful components in the gas will It may even threaten the health of operators

2. When the solid fuel is added, it directly falls into the furnace and accumulates, resulting in incomplete combustion of the fuel and waste of raw materials
