The oil slick device is connected with the bituminous coal pouring device 8 . The batching unit 1 is also provided with a boiler 7 , and a bituminous coal conveying device is also provided between the boiler 7 and the bituminous coal pouring device 8 . Described paddle settling pond comprises successively connected oil floating pond 14, sedimentation pond 15, buffer tank 16 and clear water pond 17, wherein the input end of fishing floating oil pond 14 is connected with the bottom blowdown pipe of alkaline water spray tower 4, The oil slick tank 14 is provided with a slick oil device, the bottom of the oil slick tank 14 communicates with the bottom of the settling tank 15, the top of the settling tank 15 communicates with the top of the buffer tank 16, and the bottom of the buffer tank 16 communicates with the bottom of the clear water tank 17.

配料单元1排放口排出的含粉尘烟气经过节流挡粉装置2进行初步节流挡粉（调节烟气流量并挡住粉尘）后，通过烟管喷淋装置3进行第一步喷淋降温，后经过碱水喷淋塔4进行喷淋降温，再经过液气过滤过滤后的烟气经过等离子机组去除有害物质，然后经引风机将烟气排出。碱水喷淋塔喷淋时，用水将烟气中的粉尘和轻质油冲刷下来，在碱水喷淋塔4的底部形成油污、粉尘混在碱液或水中的饱和液，通过碱水喷淋塔4的底部排污管排至田字沉淀池，经过捞浮油和沉淀后回流至碱水喷淋塔，用于提供喷淋水。捞出的浮油则利用浇烟煤装置浇烟煤后，在锅炉内焚烧，给配料单元内的低温配料供热。 The dust-containing flue gas discharged from the discharge port of the batching unit 1 passes through the throttling and blocking device 2 for preliminary throttling and blocking (adjusting the flow of flue gas and blocking the dust), and then performs the first step of spraying and cooling through the smoke pipe spraying device 3, Afterwards, the alkali water spray tower 4 is used to spray and cool down, and then the flue gas filtered by the liquid gas is passed through the plasma unit to remove harmful substances, and then the flue gas is discharged through the induced draft fan. When spraying in the alkaline water spray tower, the dust and light oil in the flue gas are washed down with water, and a saturated solution of oil stains and dust mixed in alkaline solution or water is formed at the bottom of the alkaline water spray tower 4, which is sprayed by alkaline water The sewage pipe at the bottom of tower 4 is discharged to the Tianzi sedimentation tank, and after the oil slick and sedimentation are removed, it is returned to the alkaline water spray tower to provide spray water. The slick oil that is fished out is poured with bituminous coal by the bituminous coal pouring device, and then incinerated in the boiler to provide heat for the low-temperature ingredients in the batching unit.
节流挡粉装置的作用： The function of throttling and powder blocking device:
1、改性沥青的配置过程中加入粉料时，一般是由釜的上部螺旋输送或在一个开口人工倒入，这时约抽风量小，粉料中的水蒸汽不能及时抽走会产生“冒锅”现象，危险，约风量大则把粉料抽走了，故要根据加料流程及时调节排风量； 1. When adding powder during the configuration of modified asphalt, it is generally conveyed by the upper screw of the kettle or manually poured into an opening. The phenomenon of "potting" is dangerous. If the air volume is large, the powder will be sucked away, so the exhaust air volume should be adjusted in time according to the feeding process;
2、随着配料工艺温度的上升，产生的挥发份也随之增加，之后又挥发份又降低，也需调节烟气流量。 2. As the temperature of the batching process rises, the volatile matter produced also increases, and then the volatile matter decreases again, and the flue gas flow rate also needs to be adjusted.
烟管喷淋装置3将烟气与水的提前接触，混合的时间长因而充分、降温效果好，碱水喷淋塔4喷淋低速大面积接触与凝积，既降温又浮化、洗尘。 The smoke pipe spray device 3 contacts the flue gas and water in advance, and the mixing time is long so it is sufficient and the cooling effect is good. The alkaline water spray tower 4 sprays low-speed large-area contact and condensation, which not only cools but also floats and cleans dust.
