Description

Technical Field

[0001] The present application relates to the technical field of incinerator incineration treatment, and in particular to an incinerator waste liquid feeding system. Background Art

[0002] In the production process of chemical products, environmental protection concepts should be applied from the source of the process, source reduction should be promoted, and optimization and integration of the production process should be implemented to achieve waste recycling and resource utilization, reduce the cost and consumption of chemical production, reduce waste emissions and toxicity, and reduce the adverse impact of products on the environment throughout their life cycle.

[0003] Incinerators can effectively treat hazardous organic waste from chemical production. Qualified incineration of various types of hazardous organic waste can reduce environmental pollution. Different types of hazardous organic waste have different calorific values ​​and require different temperatures for complete decomposition, necessitating different amounts of supporting gas for the incineration process.

[0004] Therefore, we can use organic waste liquid with high combustion calorific value to mix with organic waste liquid with low combustion calorific value for incineration, thereby increasing the incineration temperature of the low calorific value waste liquid. While meeting the temperature conditions for the complete decomposition of the waste liquid, we can minimize the use of combustion-supporting gas, increase the utilization of incineration heat, and increase the output of by-product steam. Utility Model Content

[0005] To increase the combustion temperature of low-calorific-value waste liquid in an incinerator and reduce the amount of combustion-supporting gas used, this application provides an incinerator waste liquid feeding system. Light-component waste liquid and heavy-component waste liquid with different calorific values ​​can be fed into the incinerator in varying proportions for incineration, thereby increasing the combustion temperature and reducing the amount of combustion-supporting gas used. This system features a high degree of automation, simple operation, low labor costs, and is economical and practical, achieving excellent incineration results and increasing byproduct steam production.

[0006] The present application provides an incinerator waste liquid feeding system adopting the following technical solutions:

[0007] An incinerator waste liquid feeding system comprises a first waste liquid tank for holding heavy component waste liquid, a second waste liquid tank for holding light component waste liquid, and an incineration atomizer for atomizing and incinerating the waste liquid;

[0008] The first waste liquid tank has a first feed port and a first discharge port. The first waste liquid tank is connected to a first discharge pipe at the first discharge port. The first discharge pipe is provided with a heavy component waste liquid pump.

[0009] The second waste liquid tank has a second feed port and a second discharge port, the second waste liquid tank is connected to a second discharge pipe at the second discharge port, and the second discharge pipe is provided with a light component waste liquid pump;

[0010] The incineration atomizer is connected with a waste liquid mixing pipe for communication with the heavy component waste liquid pump and the light component waste liquid pump.

[0011] By adopting the above technical scheme, the first feeding port is used for injecting heavy component waste liquid into the first waste liquid tank, and the second feeding port is used for injecting light component waste liquid into the second waste liquid tank. The heavy component waste liquid contained in the first waste liquid tank is discharged through the first discharge port under the action of the heavy component waste liquid pump and is transported to the waste liquid mixing pipe through the first discharge pipe; the light component waste liquid contained in the second waste liquid tank is discharged through the second discharge port under the action of the light component waste liquid pump and is transported to the waste liquid mixing pipe through the second discharge pipe. After the heavy component waste liquid and the light component waste liquid are mixed in the waste liquid mixing pipe, they are transported to the incineration atomizer for waste liquid atomization incineration treatment. The system allows light component waste liquid and heavy component waste liquid with different incineration calorific values to be mixed in different proportions into the incinerator, has certain distribution flexibility, so that the operator can accurately adjust the mixing ratio of the waste liquid according to the specific calorific value of the waste liquid and the incineration requirement, so as to achieve the best incineration effect. By mixing high-calorific-value waste liquid and low-calorific-value waste liquid, the system can improve the overall incineration temperature in the incinerator without adding too much combustion-supporting gas. This not only helps the complete decomposition of the waste liquid, but also reduces energy consumption and operating costs.

[0012] Further, the first discharge pipe is provided with a first waste liquid filter between the heavy component waste liquid pump and the first waste liquid tank, and the second discharge pipe is provided with a second waste liquid filter between the light component waste liquid pump and the second waste liquid tank.

[0013] By adopting the above technical scheme, the first waste liquid filter can filter the heavy component waste liquid before it enters the heavy component waste liquid pump, and the second waste liquid filter can filter the light component waste liquid before it enters the light component waste liquid pump. After the component waste liquids are filtered, the particulate impurities contained therein can be effectively removed. These impurities can interfere with the flowability and mixing effect of the waste liquid, and even can cause damage to the incinerator and related equipment. By filtering, the purity of the waste liquid can be ensured, which helps the component waste liquids to be more uniformly mixed in the waste liquid mixing pipe. Uniform mixing effect can ensure that the waste liquid can be fully combusted during the incineration process, thereby improving the incineration efficiency.

[0014] Further, the pipeline between the heavy component waste liquid pump and the waste liquid mixing pipe is defined as a first feeding pipe, and the first feeding pipe is provided with a first shut-off valve; the pipeline between the light component waste liquid pump and the waste liquid mixing pipe is defined as a second feeding pipe, and the second feeding pipe is provided with a second shut-off valve.

[0015] By adopting the technical scheme, the first feeding pipe can introduce the waste liquid pumped out by the heavy component waste liquid pump into the waste liquid mixing pipe, and the second feeding pipe can introduce the waste liquid pumped out by the light component waste liquid pump into the waste liquid mixing pipe. The first and second shut-off valves are arranged to enable an operator to open or close the feeding of the waste liquid at a position away from the waste liquid treatment area through a remote control system, improve the flexibility of operation, reduce the risk of direct contact of personnel with the waste liquid, and enhance the safety of the system. In an emergency, such as waste liquid leakage, equipment failure or emergency shutdown of the incinerator, the operator can quickly shut off the feeding of the waste liquid through the shut-off valves.

[0016] Further, a first check valve is arranged between the first shut-off valve and the waste liquid mixing pipe, and a second check valve is arranged between the second shut-off valve and the waste liquid mixing pipe.

[0017] By adopting the technical scheme, after the feeding of the heavy component waste liquid is stopped, the first check valve can prevent the light component waste liquid from flowing back to the first waste liquid tank; and after the feeding of the light component waste liquid is stopped, the second check valve can prevent the heavy component waste liquid from flowing back to the second waste liquid tank. The heavy component waste liquid and the light component waste liquid often have different chemical properties and physical characteristics. If one kind of waste liquid flows back into the storage tank of another kind of waste liquid, a chemical reaction or a physical change may occur, causing damage to the storage tank, the pipeline or related equipment. The arrangement of the check valves can effectively prevent such backflow phenomenon from occurring, thereby protecting the integrity and safety of the equipment. Cross-contamination between the waste liquids may affect the subsequent treatment effect and incineration efficiency. The check valves can ensure one-way flow of the waste liquids during transportation, avoiding mixing and contamination between different waste liquids.

[0018] Further, a first flow meter is arranged between the first shut-off valve and the first check valve, and a second flow meter is arranged between the second shut-off valve and the second check valve.

[0019] By adopting the technical scheme, on the first feeding pipe, the first shut-off valve, the first flow meter and the first check valve are connected in sequence, and on the second feeding pipe, the second shut-off valve, the second flow meter and the second check valve are connected in sequence. The first and second flow meters can display the flow rates of the heavy component waste liquid and the light component waste liquid in real time, enabling the operator to accurately understand the transportation of the waste liquids, which helps the operator to discover problems in time and take corresponding measures to ensure stable operation of the system. By monitoring the flow rates of the waste liquids, the operator can accurately control the feeding speed and mixing ratio of the waste liquids, which helps to improve the incineration efficiency of the incinerator and the resource utilization rate, while reducing the emission of harmful gases. In combination with the remote control system, the operator can realize automatic control of the flow rates of the waste liquids according to the display data of the flow meters, reduce the frequency and difficulty of manual intervention, and improve the degree of automation and production efficiency of the production process.

[0020] Further, the first waste liquid tank is provided with a first backflow opening, and a first backflow pipe for communicating with the first feeding pipe is connected to the first waste liquid tank at the position of the first backflow opening.

[0021] The second waste liquid tank is provided with a second backflow opening, and a second backflow pipe for communicating with the second feeding pipe is connected to the second waste liquid tank at the position of the second backflow opening.

[0022] By adopting the above technical scheme, the cooperation of the waste liquid backflow pipe and the feeding pipe enables the waste liquid to be transported through two pipelines, and the waste liquid can be transported to the waste liquid mixing pipe through the feeding pipe and can be backflowed to the waste liquid tank through the waste liquid backflow pipe. The first backflow pipe and the second backflow pipe enable the system to flexibly adjust the transportation path of the waste liquid according to actual needs. When the processing capacity of the incinerator reaches saturation or needs to be temporarily stopped, the waste liquid can be backflowed to the corresponding waste liquid tank through the backflow pipe, thereby avoiding system overload or blockage, and this load adjustment capability helps to ensure stable operation of the system. Through the provision of the backflow pipe, the system can more flexibly respond to changes in various production demands. When the waste liquid generation amount suddenly increases, the system can temporarily relieve the processing pressure by increasing the backflow amount, thereby ensuring the continuity of the production process.

[0023] Further, the first backflow pipe is provided with a first adjusting valve, and the second backflow pipe is provided with a second adjusting valve.

[0024] By adopting the above technical scheme, the provision of the first adjusting valve and the second adjusting valve enables the operator to remotely control the system to real-time adjust the flow of the heavy component waste liquid and the light component waste liquid into the incinerator, and the remote control capability improves the controllability and flexibility of the system, so that the operator can quickly adjust the transportation amount of the waste liquid according to actual needs. Through the real-time adjusting function of the adjusting valve, the operator can quickly respond to changes in the equipment state, such as fluctuations in the waste liquid generation amount and changes in the processing capacity of the incinerator, which helps to ensure stable operation of the system and avoid problems such as overload or blockage.

[0025] Further, the first waste liquid tank is provided with a first backflow opening, and a first backflow pipe for communicating with the first feeding pipe is connected to the first waste liquid tank at the position of the first backflow opening.

[0026] By adopting the above technical scheme, the waste liquid tank may generate excessive pressure during storage due to internal chemical reactions, temperature changes, or external pressure and other factors. The provision of the pressure relief opening can timely release these pressures and avoid damage to the tank body.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. The system allows light component waste liquid and heavy component waste liquid with different incineration calorific values ​​to be mixed in different proportions and enter the incinerator. The operator can accurately adjust the mixing ratio of the waste liquid according to the specific calorific value and incineration requirements of the waste liquid to achieve the best incineration effect. The setting of the first waste liquid filter and the second waste liquid filter can filter the waste liquid before it enters the pump, effectively removing particulate solid impurities, ensuring the purity of the waste liquid, and helping the waste liquid to be mixed more evenly in the waste liquid mixing pipe, thereby improving the incineration efficiency;

[0029] 2. The coordinated arrangement of the waste liquid return pipe and the feeding pipe enables the system to flexibly adjust the waste liquid delivery path according to actual needs, avoiding system overload or blockage and ensuring stable system operation. This load adjustment capability helps the system more flexibly respond to changes in various production needs;

[0030] 3. The setting of the first regulating valve and the second regulating valve enables the operator to adjust the flow rate of the waste liquid in real time through the remote control system, and quickly respond to changes in the equipment status, such as fluctuations in the amount of waste liquid generated, changes in the incinerator's processing capacity, etc., to ensure the stable operation of the system. The first flow meter and the second flow meter can display the flow rate of the waste liquid in real time, and the operator can accurately control the feeding rate and mixing ratio of the waste liquid, which helps to improve the incineration efficiency and resource utilization of the incinerator, while reducing the emission of harmful gases. The first flow meter and the second flow meter can display the flow rate of the waste liquid in real time, and the operator can accurately control the feeding rate and mixing ratio of the waste liquid, which helps to improve the incineration efficiency and resource utilization of the incinerator, while reducing the emission of harmful gases.
