The slurrying tank 1 is also fixedly connected to the exhaust gas washing tower 2 through a pipeline. A stirrer 4 is provided on the slurrying tank 1 and the buffer tank 3. A circulation pump 5 and a transfer pump 6 are provided on the pipeline connected to the slurrying tank 1. The exhaust pipeline of the exhaust gas washing tower 2 is connected to the slurry exhaust system 7. The exhaust port of the slurrying tank 1 is connected to the air inlet of the exhaust gas washing tower 2 through the exhaust gas pipeline, and the slurry discharge port of the slurrying tank 1 is connected to the spray liquid inlet of the exhaust gas washing tower 2 through the slurry pipeline. The transfer pump 6 is arranged on the pipeline between the slurrying tank 1 and the buffer tank 3 and on the pipeline between the slurrying tank 1 and the exhaust gas washing tower 2. The transfer pump 6 is configured to drive the slurry in the slurrying tank 1 to enter the buffer tank 3 and the exhaust gas washing tower 2 respectively. The circulation pump 5 is configured to drive the slurry in the slurrying tank 1 to circulate along the circulation pipeline to promote slurrying. The circulation pipeline may include a feed pipe connected between the slurry furnace bottom discharge port and the pulping tank 1 and a reflux pipe connected between a slurry outlet of the pulping tank 1 and the feed pipe. The circulation pump 5 is arranged on the reflux pipe to drive the slurry in the pulping tank 1 to circulate along the reflux pipe and the feed pipe.

[0029] In the slurry slag beating device according to the embodiment of the utility model, a beating tank 1 with a stirrer 4 is connected to the discharge port of the slurry furnace bottom through a pipeline; a buffer tank 3 with a stirrer 4 is connected to the beating tank 1 through a pipeline; a circulation pump 5 for circulating beating and a material transfer pump 6 for transferring materials to the buffer tank 3 are arranged on both sides of the beating tank 1; the tail gas generated during the beating process of the beating tank 1 is eluted by the tail gas washing tower 2, and the tail gas pipeline is connected to the slurry tail gas system 7. Each component in the device is an independent device and can be inspected, replaced and repaired separately.

[0030] In some specific embodiments, a water inlet pipe 11 and an alkali solution pipe 12 are provided on the beating tank 1. The water inlet pipe 11 can ensure the uniform addition of water during the beating process, which helps to control the concentration and fluidity of the slurry. The alkali solution pipe 12 is used to add an appropriate amount of alkali solution to adjust the pH value of the slurry so that it can achieve the best beating effect and improve the quality and performance of the slag. By providing the water inlet pipe 11 and the alkali solution pipe 12, water and alkali solution can be easily added to the beating tank 1, automatic control can be achieved, manual operation can be reduced, thereby greatly improving production efficiency, and unnecessary waste can be reduced, reducing production costs. Corresponding control valves can be provided on the water inlet pipe 11 and the alkali solution pipe 12 to control the addition of water and alkali solution.

[0031] On the basis of the above embodiment, a water meter 8 is provided on the water inlet pipe 11 and the alkali solution pipe 11, respectively. The water meter 8 can accurately measure the flow rate of water and alkali solution, so that the operator can understand and control the amount of water and alkali solution in the pulping process in real time, thereby helping to maintain the stability and consistency of the pulping process and improve product quality. In addition, the water meter 8 can also monitor whether there are leaks or other potential problems in the pipeline. Once the data of the water meter 8 is abnormal, the operator can quickly identify and take measures to avoid production interruption or greater losses. By monitoring the data of the water meter 8, the operator can promptly discover any unnecessary waste, such as excessive use of water or alkali solution.

[0032] In some specific embodiments, a water replenishment port 9 is provided on the buffer tank 3. The main function of the buffer tank 3 is to store a certain amount of slurry to cope with flow fluctuations and pressure changes in the system. When the water volume of the system is reduced due to various reasons, the liquid can be replenished in time through the water replenishment port 9 to ensure the continuous and stable operation of the system and avoid production interruptions or equipment damage caused by insufficient water. By replenishing the liquid in time through the water replenishment port 9, the liquid level in the buffer tank 3 can be kept within a suitable range, thereby ensuring that the system can operate continuously and efficiently. This helps to reduce the loss of production time caused by downtime for water replenishment and improve production efficiency.

[0033] On the basis of the above embodiment, the leaching liquid used in the tail gas washing tower 2 is a pulping liquid, which is a mixture of water and alkali solution. Through the leaching process, impurities and pollutants in the slurry can be effectively removed, thereby improving the purity and quality of the slurry, which is of great significance for the transportation of slurry slag. The pollutants in the slurry may cause corrosion or blockage to the production equipment, affecting the normal operation of the equipment. The use of leaching liquid for leaching can effectively reduce the damage of these pollutants to the equipment and extend the service life of the equipment. Preferably, the proportion of alkali solution is 5% of the total amount of the leaching liquid.

[0034] In some specific embodiments, a plurality of manholes 10 are provided at intervals on the pipeline. The design of the manhole 10 allows maintenance personnel to easily open and enter the interior of the pipeline, thereby facilitating cleaning and maintenance operations, which is essential to ensure the normal operation of the equipment. Through regular inspection and maintenance, potential problems can be discovered and solved in a timely manner, thereby avoiding greater losses. The manhole 10 is usually equipped with a vent or ventilation device, which helps to provide air circulation from the pipeline to the interior of the equipment, reduce the accumulation of odors and pollutants, and thus improve operational safety.

[0035] On the basis of the above embodiments, a liquid level gauge is provided on the pulping tank 1 and the buffer tank 3. The liquid level gauge can monitor the liquid level in the pulping tank 1 and the buffer tank 3 in real time, which helps to prevent the occurrence of safety accidents such as liquid overflow or oil and gas explosion in the tank, thereby improving the safety of the processing process. Through the real-time monitoring of the liquid level gauge, the transportation and production personnel can timely understand the status of the liquid in the tank, ensure that the liquid is fully loaded, and avoid waste caused by dissatisfaction or damage to the equipment caused by overloading. The liquid level gauge can also monitor whether the liquid reserves have reached the maximum capacity of the equipment, and send an alarm signal when the capacity limit is reached or an accidental overflow occurs, reminding the staff to deal with it in time, which helps to timely discover and solve potential problems and avoid production interruptions or greater losses.

[0036] In some specific embodiments, a temperature sensor is provided on the pipeline between the slurry furnace and the pulping tank 1 and on the tail gas washing tower 2. The temperature sensor can monitor the temperature of the fluid in the pipeline in real time and provide accurate temperature data for the pulping process. This helps to accurately control the temperature in the slurry furnace and the pulping tank 1, ensuring that the pulping process is carried out within the optimal temperature range, thereby improving the quality and performance of the slurry. By monitoring the pipeline temperature in real time, the temperature changes during the pulping process can also be understood, thereby optimizing the pulping process.

[0037] On the basis of the above embodiment, two parallel pipelines are provided on the tail gas washing tower 2 for elution. Compared with the single pipeline water supply, the two parallel pipelines can greatly increase the water supply capacity and ensure that the water supply is sufficient during the elution process. The parallel design of the two pipelines can also divert the water flow, thereby reducing the flow resistance and pressure loss in the water supply pipeline, which helps to maintain the stability of the water supply pressure and prevent the elution effect from being affected by insufficient pressure. At the same time, when one of the pipelines fails, the other pipeline can continue to supply water to ensure the continuity of the elution process.

[0038] On the basis of the above embodiment, a filter is further provided between the pulping tank 1 and the tail gas washing tower 2. The filter can remove the coarse particles, impurities and incompletely crushed materials generated during the pulping process, thereby ensuring that the tail gas does not contain coarse particles, impurities and incompletely crushed materials, which helps to improve the product quality and stability in the subsequent processing process, and is also conducive to extending the service life of the slurry tail gas system 7.

[0039] The utility model has at least the following advantages:

[0040] (1) The slag has enhanced fluidity after pulping, and can be more easily transported through pipelines or other transportation methods, reducing the occurrence of blockages and failures, thereby improving transportation efficiency.

[0041] (2) During the slag slurrying process, the dust and fine particles in the slag can be effectively absorbed by the liquid, reducing the dust phenomenon during transportation, which helps to reduce pollution to the surrounding environment and protect air quality.

[0042] (3) The slag after pulping is easier to carry out subsequent treatment, such as sorting and recycling, which helps to further improve the resource utilization rate of slag and reduce the generation of waste.

[0043] (4) Through the pulping process, the volume of the slag can be compressed to a certain extent, thereby reducing the space and number of vehicles required during transportation, which helps to reduce transportation costs.
