Description

Technical Field

[0001] The invention belongs to the technical field of waste liquid processing, and in particular relates to an acrylonitrile waste liquid incineration and recycling system. Background Art

[0002] Acrylonitrile wastewater mainly comes from wastewater produced by acrylonitrile production, ABS plastic production, and thiamine production, and contains a large number of pollutants, such as acrylonitrile, acetonitrile, hydrocyanic acid, heavy components (polymers), ammonium sulfate, sodium carbonate, and catalyst powder. Acrylonitrile wastewater has complex components, high toxicity, and contains ammonium sulfate and salt. It is very difficult to treat. It is necessary to comprehensively consider nitrogen oxide emissions, sulfur corrosion, salt corrosion, and reasonable use of energy. Therefore, more complex treatment processes and systems can meet the requirements. At present, the commonly used industrial treatment methods for the above wastewater include biological methods, wet catalytic oxidation methods, and high-temperature incineration methods.

[0003] As for the high-temperature incineration method, it has the characteristics of simple process and efficient processing, strong adaptability to the flow rate and component fluctuations of acrylonitrile wastewater, and can achieve complete oxidation and decomposition of harmful substances in acrylonitrile wastewater. The specific description is: for waste liquid with calorific value, it is atomized into small droplets by compressed air through a waste liquid gun and then sprayed into the incinerator. Among them, the upper part of the incinerator is the reduction section. In the reducing atmosphere, more CN in the waste liquid is reduced to N2, and NOX is generated as little as possible. At the same time, some CO and H2 are produced. The lower section of the incinerator is the oxidation section. The high-temperature flue gas generated in the reduction section reacts with excess air, and is completely oxidized, burned, and decomposed into harmless or easy-to-handle components under the action of high temperature and turbulence.

[0004] In the prior art, when waste liquid is treated by high-temperature incineration method, not only a large amount of fuel is consumed to achieve the high temperature required for incineration, but also the operating cost is high, and the waste gas after combustion is generally discharged into the external environment after denitration treatment, resulting in energy waste. At the same time, for the combustion air transported to the incinerator, it needs to absorb a certain amount of heat in the furnace to heat up, and then play its combustion-supporting role, which affects the temperature environment in the incinerator to a certain extent, limits the incineration process, increases the combustion cost, affects the economic benefits in the factory, and cannot meet the use requirements. For this reason, a system for incinerating and recycling acrylonitrile waste liquid is provided, which has reasonable design, simple structure, convenient processing, and can centrally collect steam after incineration and denitration, and fully exchange heat in the transportation process of combustion air, so that it can obtain the temperature in front of the furnace in advance, and reduce the possibility of affecting the temperature in the incinerator. It can not only save fuel input and consumption, but also reuse steam energy to save resources, ensure the economic benefits of processing in the factory, and effectively meet the use requirements.

A heat exchange tube 9 with a reciprocating rotation design is arranged in the placement tank 2. One end of the heat exchange tube 9 passes through the heat exchange tank 1, and the other end passes through the outside of the placement tank 2. A combustion-supporting air supply pipe 10 with a mountain shape and connected to the air outlet component 6 is also arranged in the placement tank 2. The combustion-supporting air supply pipe 10 completes the secondary heat exchange at the heat exchange tube 9 and is then input into the external combustion-supporting pipeline.

Under the condition of smooth transportation, the combustion air in the transportation pipe group 4 can be preheated to ensure the working process.

[0035] In order to guide the steam delivery process in the heat exchange tank 1, especially to ensure that it can be guided to the delivery pipe group 4 to ensure the heat exchange effect, a guide component 12 is arranged between two adjacent spoiler components 3, and the guide component 12 includes a guide plate 121 designed in an acute angle, which is located at the geometric center of the delivery pipe group 4 set up in a U shape, and promotes the steam delivery.
