[0029] After the water is boiled, the liquid temperature rises sharply, which takes 10 minutes. The high-temperature liquid transmitted by the distillation gas phase pipe 109 is cooled by the cooling water inlet pipe 202 and the cooling water return pipe 209, and the non-condensable gas vent pipe 205 at the outer end of the cooler 204 is used to vent to the second floor platform. The liquid collection pipe 206 of the cooler 204 extends from the second floor platform to the first floor, and the non-condensable gas vent pipe 205 is equipped with a flame arrester to discharge the non-condensable gas to a higher position. When the initial distillation point of the liquid reaches 102°C and the temperature rises to 116°C, the evaporated light yellow turbid liquid is continuously collected. The initial distillation point of the liquid is 1 When the temperature is continuously raised from 02℃-108℃ to 170℃, the evaporated light yellow liquid is continuously collected. The initial boiling point of the liquid is 108℃ and the temperature is raised to 170℃. During the dry distillation stage of the residue from 28 to 170℃, the temperature rises sharply, and basically no liquid is collected in 6 minutes. The high calorific value products of the wastewater are mainly concentrated in the distillation residue. The yield of the distillation residue before the liquid temperature is 128℃ is 22.7%, and the yield before 170℃ is 16.67%. The calorific value is 5530kcal / kg. Before this temperature, the distillation residue is a sticky semi-solid that can maintain fluidity, can be ignited and can continue to burn. When the liquid temperature exceeds 200℃, a non-fluid viscous solid is obtained after dry distillation, with a yield of 7.5% and a calorific value of 5749kcal / kg. After the waste liquid treatment is completed, the valve of the slag discharge pipe 102 is opened, and the reaction waste is discharged from the slag discharge pipe 102 to achieve the reaction treatment of the waste liquid in the pyrolysis workshop.
[0030] Through the above steps, by increasing the number of heating coils inside the stirring kettle, each of which is connected with an elbow and placed horizontally to avoid the need to cut the stirring blades due to obstruction by the stirrer, a slag discharge pipe 102 is used to separate solid waste from waste liquid, which is convenient for subsequent treatment and disposal, reduces the volume of waste liquid, and makes the waste liquid purer. At the same time, the slag discharge pipe 102 can effectively remove impurities and solid waste in the waste liquid, improve the quality of the waste liquid, and reduce pollution to the environment. The heating kettle on-site thermometer 107 and the heating kettle remote thermometer 108 can be used to monitor the temperature of the heating kettle in real time to ensure that it is within the normal operating range, avoid overheating or too low a temperature, avoid abnormal temperature of the heating kettle that may cause equipment failure or reduced treatment effect, and can promptly detect temperature abnormalities, so as to take measures to repair the equipment or adjust the operating parameters, reduce equipment failure and downtime, and accurately analyze the temperature data to optimize the operating parameters, improve the treatment process, and improve the waste liquid treatment efficiency. In order to improve the efficiency and results of waste liquid treatment, the cooling medium is introduced into the waste liquid treatment device by using the cooling water inlet pipe 202 and the cooling water return pipe 209, and the heat in the waste liquid is transferred to the cold water by means of heat exchange, thereby effectively reducing the temperature of the waste liquid and avoiding the occurrence of equipment damage or reduced treatment efficiency of the waste liquid treatment device due to excessive temperature. The cooling water inlet pipe 202 and the cooling water return pipe 209 can avoid thermal damage to the equipment, thereby extending the service life of the equipment and improving the safety of the equipment, thereby reducing the energy demand for subsequent heating. The non-condensable gas vent pipe 205 at the outer end of the cooler 204 is used to vent to the second floor platform, and the liquid collection pipe 206 of the cooler 204 partially extends from the second floor platform to the first floor, and the non-condensable gas vent pipe 205 is equipped with a flame arrester to discharge the non-condensable gas to a higher position to avoid its direct dissipation to the ground, thereby reducing the pollution to the ground air and the surrounding environment. At the same time, the condensable gas may contain chemicals that are harmful to the human body.By extending the vent of non-condensable gas to the second-floor platform, it can ensure that operators are away from the emission area of non-condensable gas, reduce their risk of contact with harmful gases, and improve the safety of the working environment. The distillation gas phase collection pipe 212 is used to effectively collect these gases, avoid waste and environmental pollution, maximize the use of resources, and help improve the economic benefits of recycling. At the same time, some harmful or polluting gases are easily generated during the waste liquid treatment process. The distillation gas phase collection pipe 212 is used to collect the gas and guide it to a suitable treatment facility, thereby reducing the emission of harmful gases into the atmosphere, reducing pollution to the environment and harm to health, and improving the safety of the working environment. The distillation gas phase collection pipe 212 is divided into six groups connected by elbows at the ends to more effectively collect the gas generated in the waste liquid treatment process. The six groups of distillation gas phase collection pipes 212 can be collected separately according to different gas components and flow rates to avoid gas leakage and pollution, thereby improving the collection efficiency, reducing gas emissions and waste of resources. A cooling pipe jacket 213 is provided at the outer end of the collecting pipe 212, through which the cooling medium can flow through the jacket, thereby effectively reducing the temperature of the gas, avoiding damage to the equipment and pipelines by the high-temperature gas, and reducing the impact on the subsequent processing equipment. At the same time, the cooling medium flowing through the cooling pipe jacket 213 can effectively cool the gas, causing it to condense into a liquid state instead of dispersing, thereby improving the collection effect. When the waste liquid flows in the collecting pipe, the collecting pipe remote thermometer 215 and the collecting pipe on-site thermometer 214 are used to monitor the temperature change of the waste liquid in the collecting pipe in real time, which helps the operator to understand the temperature change during the waste liquid treatment process, and adjust the operating parameters or take necessary measures in time to ensure the stability and quality of the treatment effect, avoid equipment failure or reduced treatment effect due to abnormal temperature, make adjustments and treatments in time, and avoid serious equipment failure and processing interruption. Secondly, the collecting pipe remote thermometer 215 and the collecting pipe on-site thermometer 214 are used to record and save temperature data, which is convenient for subsequent data analysis and processing.
