Description
Technical Field
The invention relates to the technical field of treatment of tail end waste gas in medical chemical industry, in particular to a complementary system of a gas-liquid furnace and a regenerative incinerator for waste gas treatment and a use method thereof.
Background
With the development of global economy and the acceleration of urban process, the discharge of industrial wastewater and waste gas is increased, the pollution is serious, and the organic wastewater containing BOD >100mg/L, COD >2000mg/L is commonly called high-concentration organic waste liquid. These waste solutions often have one or more of the deleterious characteristics of flammability, corrosiveness, acute toxicity, leaching toxicity, reactivity, infectivity, carcinogenicity, teratogenicity, mutagenicity, etc. Common methods for treating organic waste liquid are solvent extraction, membrane separation, oxidation, adsorption III and incineration. Wherein, the solvent extraction method, the membrane separation method, the oxidation method and the adsorption method are difficult to thoroughly eliminate the harm of organic waste liquid and easily cause secondary pollution.
In addition, the emission of VOCs in China mainly comes from fixed source combustion, road traffic solvent product use and industrial processes. Among the many man-made sources, industrial sources are the main sources of VOCs pollution, and have the characteristics of concentrated emission, high emission intensity, high concentration and complex components. The harm of VOCs to the human body is mainly twofold: one is that the harmful components directly affect the health of human bodies, and the two VOCs can form PM2.5 precursors, so that the health of human bodies is indirectly affected. According to the principle of generating VOCs in the atmosphere and the physicochemical properties of VOCs, the control technology can be divided into two main types, namely process control and end control. The process control is aimed at the production process of VOCs, and the generation of VOCs is reduced in principle, and is generally realized through process lifting, technical transformation and leakage control. The tail end control aims at the chemical characteristics of the VOCs, is applied to the treatment of the exhaust gas of the VOCs, and controls the emission of the VOCs by using methods such as combustion, decomposition and the like. At present, the waste liquid is treated by an incineration method at home and abroad, incineration equipment of waste gas is various, and different furnace types can be adopted for different industrial waste liquids and waste gas.
The gas-liquid incinerator is mainly used for treating liquid waste which can be conveyed by a pump. A simple structure, typically a refractory lined cylinder (horizontally or vertically placed), is fitted with one or more burners. The principle is that waste gas and waste liquid are burnt directly through nozzle to be atomized into fine liquid drops, and the fine liquid drops are burnt in suspension state in a high-temperature flame area, the burning temperature is controlled to be about 1000-1150 ℃, the highest temperature cannot exceed 1200 ℃, and the lowest temperature cannot be lower than 900 ℃. The temperature of the burned flue gas can be recycled through a waste heat boiler to generate steam, the temperature of the flue gas is reduced from 1100 ℃ to about 300 ℃ after the flue gas is recycled, and the lowest temperature cannot be lower than 280 ℃.
The heat accumulating incinerator (RTO) waste gas treating apparatus is one kind of efficient organic waste gas treating apparatus. Compared with the traditional catalytic combustion and direct combustion type thermal oxidation furnace (TO), the catalytic combustion and direct combustion type thermal oxidation furnace has the characteristics of high thermal efficiency (more than or equal TO 95%), low running cost, capability of treating waste gas with high air quantity, medium and low concentration, and the like, and can also perform secondary waste heat recovery when the concentration is slightly high, so that the production running cost is greatly reduced. The main working principle of RTO is to heat the organic waste gas to 760 ℃ or higher, so that VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a special ceramic heat accumulator to heat the ceramic body to store heat, and the heat is used for preheating organic waste gas which enters subsequently. Thereby saving fuel consumption for exhaust gas warming. The ceramic regenerators should be divided into more than two (including two), each regenerator being subjected to the procedures of heat accumulation, heat release, cleaning, etc. in turn.
According to different local environmental protection policies, a plurality of parks and factories are required to use 2 sets of RTO systems to completely treat the discharged waste gas, so that the investment cost is greatly increased; in addition, the RTO can treat the waste gas after heating for about four hours under the condition that continuous working conditions cannot be achieved, and if the RTO adopts a hot standby system to assist in heat standby, the heating energy consumption of the system can be greatly increased. In addition, the waste gas of chemical industry and pharmaceutical industry is often various in variety, and enterprises are difficult to solve all waste gas in the field by using one incinerator.
