As a main approach for clean and efficient utilization of coal, in recent years, coal chemical industry is developed rapidly in China, a plurality of large-scale coal chemical engineering projects are newly developed in most areas of the country, and the pollution related to the environment is just the main reason for limited popularization of coal chemical enterprises. For example, in the process of preparing natural gas from coal, various acidic waste gases, especially low-formic acid gas, containing extremely high H content are generated2S concentration, some up to hundreds of thousands mg/m3And also contains various other harmful substances and hydrocarbons, so that the organic waste gas has a certain heat value and is called as organic waste gas. The acidic organic waste gas needs to be treated harmlessly, otherwise, the acidic organic waste gas pollutes the atmospheric environment and affects the health of people.
The currently applied high-sulfur organic waste gas treatment technologies include adsorption, biological, membrane-based absorption, catalytic combustion, and the like. The adsorption method uses an adsorbent to absorb the waste gas, is suitable for the conditions of low concentration and large air quantity, and needs to regularly regenerate the adsorbent to ensure the removal effect; biological processes use microorganisms to ultimately decompose organic matter in exhaust gas to CO2And H2O, the method has low cost and simple process, but occupies large area and can degrade organic mattersLess; the membrane-based absorption method uses a hollow fiber microporous membrane to absorb organic matters in the waste gas and transfer the organic matters into an absorbent, the whole process flow looks simple and has high efficiency, but the requirement on the absorbent is met, the absorbent is nontoxic and harmless, and the pressure of the waste gas on two sides of the membrane is required to be greater than that of the absorbent in the absorption process, so that the whole process is continuously effective; the catalytic combustion method can decompose the waste gas when less auxiliary fuel is consumed, and has the defects of higher catalyst cost, further treatment of secondary pollutants and improvement of the treatment cost of the whole process. Therefore, the methods have the problems of high cost, incomplete treatment, easy secondary pollution, energy waste and the like in different degrees.
In recent years, the introduction of high sulfur exhaust gas into boiler combustion has been attracting attention, but in practice it has been found that direct introduction into boiler combustion produces high concentrations of H at early stages of combustion or in localized locations within the furnace due to untimely or localized oxygen deficit from the supply of oxygen2S and elemental sulfur, as a result, high-temperature corrosion occurs on the heating surface of the boiler, the safety of the heating surface of the boiler is seriously influenced, and meanwhile, elemental sulfur occurs in a tail flue gas desulfurization system, so that the treatment of a desulfurization byproduct and desulfurization waste liquid is directly influenced, and the long-term continuous operation cannot be normally carried out. Therefore, a new technology for harmless resource recycling of high-concentration sulfur-containing waste gas with high efficiency and low cost is urgently needed to be developed.

Description of reference numerals: the device comprises a high-sulfur waste gas spray gun 1, an air duct shell 2, an annular air duct 3, a high-sulfur waste gas inlet 4 and an oxygen-enriched or pure oxygen inlet 5.
Detailed Description
The present invention will be further described with reference to the following examples. The following examples are set forth merely to aid in the understanding of the invention. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
The implementation process of the invention is shown in fig. 1 and fig. 2: the high-sulfur waste gas rich combustion device in figure 1 is installed in the combustion area of a boiler, a high-sulfur waste gas spray gun 1 is arranged in the center of a burner, waste gas enters a furnace through the spray gun from a high-sulfur waste gas inlet 4 of the high-sulfur waste gas spray gun 1, an oxygen-enriched or pure oxygen annular air channel 2 is arranged at the periphery of the spray gun and used for providing oxygen-enriched or pure oxygen required by waste gas decomposition and combustion, a certain distance 3 is kept between the annular air channel 3 and the central high-sulfur waste gas spray gun 1, and the oxygen-enriched or pure oxygen is sent in through two inlets 5 at the other end of an.
After the high-sulfur waste gas enters the furnace, the high-sulfur waste gas is quickly decomposed and combusted in a high-temperature and oxygen-enriched environment, SO that sulfides and hydrocarbons in the waste gas are fully reacted, converted into gas-phase components such as SO2, CO2 and H2O, and absorbed by a purification device at the tail of the boiler. Because the combustion-supporting gas of oxygen enrichment and pure oxygen is adopted, the high-sulfur waste gas can not generate H2S, elemental sulfur and other more harmful components, the generated flue gas amount is greatly reduced compared with the combustion-supporting gas of air, the influence on the heating surface and heat transfer of the boiler and the influence on auxiliary equipment of the boiler are small, and the improvement is not needed. Therefore, the harmlessness, the resource utilization and the energy recovery utilization of the high-concentration sulfur-containing waste gas are finally realized.
The technical points of the invention are as follows:
(1) high-sulfur organic waste gas is directly fed into a boiler by utilizing a combustion boiler (coal-fired, gas-fired or oil-fired boiler and the like) provided by a coal chemical industry enterprise, and is fully decomposed to generate SO under the high-temperature and oxygen-enriched environment2And H2Removing SO from O and other substances by using existing desulfurization facilities of boiler2And the quick decomposition of harmful substances in the high-sulfur waste gas and the full recycling of the heat value are realized.
(2) The biggest problem of burning high-sulfur exhaust gas in a boiler is that H is easily generated due to insufficient oxygen2S, and separating out the simple substance S. The former can cause high-temperature corrosion of a boiler heat receiver, and influence the safe and economic operation of the boiler; the latter can affect the desulfurization system at the tail of the boiler, cause the quality of the desulfurization product to be reduced, affect the selling price of the desulfurization by-products and even can not be sold in the market. Aiming at the problems, the core technology of the invention is to adopt oxygen-enriched or pure oxygen to form high-concentration oxygen atmosphere around the high-sulfur waste gas when the high-sulfur waste gas enters the hearth SO as to ensure sufficient oxidizing atmosphere and convert most of sulfides in the high-sulfur waste gas into SO in time2Prevent H2S and elemental sulphur generation.
The specific technical scheme of the invention is as follows:
(1) the high-sulfur waste gas jet hole is newly arranged in the combustion area of the boiler, and the original burner hole on the boiler can be utilized to directly replace the burner hole.
(2) In the opening is arranged a high sulfur exhaust gas rich combustion device of the embodiment, which comprises a central high sulfur exhaust gas lance 1 and a peripheral annular air duct 3.
(3) The oxygen concentration required for the decomposition or combustion of the high-sulfur waste gas is very important, and the higher the concentration is, the more favorable the quick and thorough decomposition and combustion of the waste gas are, and the H is avoided2S and elemental sulfur. Therefore, the oxygen-enriched concentration is generally 25-90% (volume concentration, wherein more than 90% is pure oxygen).
(4) The temperature of the oxygen-enriched or pure oxygen can be normal temperature, or the temperature of the oxygen can be increased according to the heat value of the high-sulfur waste gas, and the range is 25-300 ℃.
The high-sulfur waste gas spray gun 1 is a common low-heat value gas nozzle and can be purchased in the open market according to the heat value, the flow and the inlet pressure.
The oxygen-enriched or pure oxygen annular wind provides oxygen required by high-sulfur waste gas decomposition and organic matter combustion on one hand, and on the other hand, after the waste gas enters the boiler, an annular high-speed gas film is formed around the waste gas to prevent reducing atmosphere or inert gas in a hearth from permeating into waste gas jet flow to prevent H from being formed2S and elemental sulfur, ensuring that the waste gas has sufficient oxygen to carry out chemical reaction.
The wind speed of the oxygen-enriched or pure oxygen annular wind is designed to be 50-80m/s at a high speed so as to ensure that the annular wind jet can penetrate through the center of the hearth and ensure that the high-sulfur waste gas can play a role in effective reaction time.
The area size of the outlet of the annular air duct 3 is determined according to the wind speed and the required wind quantity. The distance between the air duct shell 2 and the central high-sulfur waste gas spray gun 1 is determined according to the capacity and the size of the burner, and is generally 50mm-200 mm.
