Description

Automatic treatment incineration system and process for salt-containing sulfur-containing waste liquid Technical Field The invention relates to the technical field of waste liquid incineration, in particular to an automatic treatment incineration system and process for salt-containing sulfur-containing waste liquid. Background The incineration of industrial waste liquid mainly comprises high-temperature oxidation, rotary kiln incineration, fixed bed incineration and other modes. The high temperature oxidation technique is a method of burning waste liquid by high temperature and oxygen. It is usually carried out in a high temperature combustion furnace, and the waste liquid is heated and oxidatively decomposed under high temperature and high pressure environment. The method has the advantages of good treatment effect and capability of treating various types of waste liquid. The disadvantage is high energy consumption and high cost. Rotary kiln incineration is one method of treating waste streams using rotary kiln reactors. In a rotary kiln, the waste liquor is transferred to a high temperature for drying and combustion decomposition. The method has the advantages of low energy consumption and no secondary pollution. The disadvantage is that the waste liquid needs to be treated into solid substances first, and the treatment time is long. The fixed bed incineration is to directly burn and decompose the waste liquid by using a fixed bed reactor, and belongs to a conventional waste liquid treatment technology. The waste liquid is sprayed on the fixed bed and then oxidized and decomposed at high temperature. The method has the advantages of good treatment effect and lower cost, and can treat some waste liquid which is difficult to treat, such as particulate matters, halides and the like. The disadvantage is that secondary pollution is easy to generate, and the purified gas needs further treatment. The process flow of ‌ waste liquid combustion is divided into ‌ pretreatment ‌, wherein preliminary pretreatment is usually needed before the waste liquid enters the main treatment system. The link mainly comprises the operations of screening, sand setting, oil-water separation and the like. The screening is to remove large-particle suspended matters in the waste liquid through a screen, the sand setting is to precipitate sand grains and other solid particles with larger density in the waste liquid by utilizing the action of gravity, and the oil-water separation is to separate oil and water from the waste liquid through a standing method or a centrifugal method or the like ‌. ‌ incineration ‌, namely pretreating the waste liquid, and then sending the pretreated waste liquid into an incineration device for high-temperature thermal oxidative decomposition. The high temperature environment in the incinerator oxidizes and decomposes organic matters to produce harmless substances such as water, carbon dioxide and the like, and the harmless substances are discharged into the atmosphere. In the incineration process, it is necessary to ensure a good atomization effect and to supply sufficient combustion air to obtain stable combustion conditions. ‌ waste heat recovery ‌. High temperature flue gas generated by incineration is subjected to heat exchange through a waste heat boiler to generate steam. The process not only recovers waste heat, but also can further reduce the temperature of the flue gas, and is convenient for subsequent treatment ‌. ‌ dedusting and blowdown ‌, namely enabling the flue gas after waste heat recovery to enter a venturi deduster to remove fly ash and dust. The flue gas after dust removal is directly discharged to the atmosphere after meeting the environmental protection requirement. The whole flue gas flow is in a negative pressure state, so that safety ‌ is ensured. ‌ auxiliary equipment and system ‌ the incineration equipment also comprises auxiliary equipment and systems such as a booster pump, a blower, an induced draft fan, a boiler dosing system, a boiler blow-down system, an ash salt conveying/packaging system and the like, and the smooth operation ‌ of the incineration process is ensured. ‌ Waste liquid combustion ‌ thoroughly decomposes pollutants ‌, namely the waste liquid combustion can thoroughly decompose organic matters in the waste liquid through high-temperature combustion, and convert the organic matters into harmless substances such as water, carbon dioxide and the like, so that the environmental pollution risk is reduced. ‌ reduction and recycling ‌, namely the combustion process can realize reduction of waste, reduce the volume of waste liquid, and recycle heat generated by partial combustion to realize recycling ‌. ‌ treatment of various types of waste liquid ‌ the incineration method is suitable for treating high-concentration, toxic and harmful liquid wastes, especially those with high concentration, complex composition and no recycling value of pollutants. ‌ high-efficiency treatm
