Ignition device of fire-spraying opening of gasifier and treatment process thereof

Abstract

The invention relates to an ignition device of a fire-spraying opening of a gasifier. The ignition device comprises an electric-heating pipe for ignition, an electric-heating pipe for heating, small air-supplying pipes, an air room, a combustion gas pipe, a gas conveying pipe and time relays, wherein a plurality of time relays are electrically connected with the electric-heating pipes and an air blower respectively; the combustion gas pipe close to the fire-spraying opening is a gas conveying pipeline having two open ends and a cylindrically-swollen middle; the two electric-heating pipes and the air room are contained in the cylindrically-swollen part of the combustion gas pipe; a plurality of small air-supplying pipes are fixed to the top of the air room; the two electric-heating pipes are arranged around the small air-supplying pipes and spaced in a definite distance; and the pipeline at the lower end of the combustion gas pipe is connected with the combustible gas conveying pipe from a gasifying room. As the ignition device is used, the combustible gas reaching the fire-spraying opening is electrically preheated, so that the water vapor generated at the beginning of gasification is eliminated, i.e., the temperature is increased for the convenience for ignition; and simultaneously, the oxygen-containing air necessary for combustion is conveyed to the combustible gas reaching the fire-spraying opening, so that the one-time ignition is ensured. Therefore, the problem that the combustion gas from the gasifying room spreads all over the place along with green smoke and odour due to the unsuccessful ignition is avoided.

Description

technical field [0001] The invention relates to the technical field of gasifiers, in particular to an ignition device and a treatment process for a gasifier burner port. Background technique [0002] We often see the smog of burning grass in the fields covering the sky, the waste residue outside the timber processing factory piled up like mountains, and the husks of chestnuts harvested in mountainous areas are rotten enough to dye the creek. The inventor runs more than 30 township enterprises. Years, I have a deep feeling for the surrounding environment. [0003] Gasification technology is a great invention, especially in today's society that pays attention to environmental protection and energy recycling. Using straw, sawdust, garbage, clothing factory rags and other wastes containing combustible components, the gasification chamber of the gasifier In the high temperature state, it reacts with insufficient supply of oxygen to generate flammable mixed gases such as carbon m...

AI Technical Summary

Problems solved by technology

[0004] Why has such a good technology not been widely promoted and applied in the market so far? Because most of the products in the prior art have the following fatal defects: 1. tar clogs the pipeline; 2. the water content in the waste is difficult to control, and it is difficult to ignite the furnace; the combustible gas discharged in more than 20 minutes before the furnace is raised Green smoke filled the air and could not be ignited; 4. Combustible gas is both flammable and explosive, and the safety is difficult to control

[0005] If these problems are not overcome, the masses will not accept them. For example, during the gasification process of the gasifier, a large amount of tar condensate produced will adhere to the pipe wall, increase wind resistance, and block the pipe. After more than half a day, the stench produced by tar will permeate the working environment and will not go away for a long time

The inventor once used the method of filtering combustible gas with sand, which was effective, but the sand was quickly blocked by tar, and it was troublesome and uneconomical to replace the sand too frequently; Incomplete, with secondary treatment until the third series of series treatment, the tar is eliminated, but the combustible gas can not be ignited

[0006] The gasifier will not only produce tar to pollute the environment, but what is even more annoying is that after the gasifier is ignited, for about 20 minutes in the early stage, the ignition port of the gasifier cannot be ignited, not only the lighter, but also the high-voltage electric spark. Not to mention, the combustible gas produced in the past 20 minutes carried green smoke and stench and continued to spread in the working environment, making it difficult for people to gain a foothold
