Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment equipment technology, and in particular to a gas supply system for incineration workshops. Background Technology

[0002] The gas supply system in an incineration plant is crucial in industrial production, providing essential gas support for various equipment and production processes. With continuous industrial development, the scale and production efficiency of incineration plants are constantly increasing, placing higher demands on the stability, reliability, and gas quality of the gas supply system. A stable and reliable gas supply system ensures the normal operation of equipment within the incineration plant, improves production efficiency, reduces downtime and equipment damage caused by gas supply problems, thereby lowering production costs and enhancing the company's economic benefits. Simultaneously, a high-quality gas supply ensures the adequacy and environmental friendliness of the incineration process, reducing the emission of harmful gases and meeting increasingly stringent environmental requirements.

[0003] Incineration plants typically employ a single-path gas supply method. Air is usually compressed by an air compressor and then delivered to various equipment within the plant via a single pipeline. This uniform supply method applies to both instrumentation equipment with high gas quality requirements and industrial equipment with large gas volume demands, without differentiating between the specific needs of different equipment. In the gas dehydration stage, refrigerated dryers are often used to remove moisture from the compressed air. The working principle of a refrigerated dryer is to cool the compressed air through refrigeration, causing water vapor to condense into liquid water before being discharged.

[0004] Regarding the aforementioned technologies, during the rainy season in summer, the humidity in the air increases significantly. During operation, the dehumidification capacity of refrigerated dryers is insufficient to achieve the expected results, leaving the air still with a high moisture content, and the dryer itself will also contain some moisture. In this situation, the refrigerated dryer not only fails to achieve its efficient dehumidification function, rendering it ineffective, but also leads to an increase in the moisture content of the air passing through it. Industrial equipment has a high demand for air with relatively low moisture content requirements; therefore, the air passing through the refrigerated dryer actually increases its lifespan. Utility Model Content

[0005] In order to extend the service life of the equipment, this application provides a gas supply system for an incineration plant.

[0006] This application provides a gas supply system for an incineration plant, which adopts the following technical solution: A gas supply system for an incineration plant includes an air compressor unit, a first gas supply branch, and a second gas supply branch. The first and second gas supply branches are respectively connected to the air compressor unit via pipelines. An industrial air storage tank is connected to the end of the first gas supply branch, and an instrument air storage tank is connected to the end of the second gas supply branch. A linkage switching component is provided between the first and second gas supply branches to switch the connection state between them. Both the first and second gas supply branches are connected to a refrigerated dryer to remove moisture from the gas. One end of the first gas supply branch is connected to a bypass pipeline, which is connected to the industrial air storage tank. One end of the first gas supply pipeline is equipped with an on / off valve to control the connection state between the first gas supply pipeline and the refrigerated dryer. When the first gas supply pipeline is not connected to the refrigerated dryer, the gas enters the industrial air storage tank from the bypass pipeline.

[0007] By adopting the above technical solutions, the industrial air storage tank can adapt to the demand for large-flow instantaneous gas consumption, while the instrument air storage tank focuses on maintaining stable pressure and improving gas supply adaptability. The linkage switching component can quickly switch the connection status between the second gas supply branch and the first gas supply branch, allowing the second gas supply branch to temporarily supply gas to the first gas supply branch. The first gas supply branch is equipped with a bypass pipeline, which can bypass the refrigerated dryer and supply gas directly. When it is the rainy season and the air humidity is high, the on / off valve opens, and the gas is transported from the bypass pipeline to the industrial air storage tank, reducing the excessive humidity in the refrigerated dryer, increasing the gas humidity, thereby reducing the wear and tear on the equipment and extending the service life of the equipment.

[0008] Optionally, the linkage switching component includes a pneumatic shut-off valve, the outlet of which is connected to the first air supply branch via a supplementary pipeline, and the inlet of which is connected to the second air supply branch via a supplementary pipeline.

[0009] By adopting the above technical solution, when the pressure of the industrial air storage tank is insufficient, the pneumatic shut-off valve can be opened instantly, so that the gas from the second air supply branch can be quickly replenished to the first branch through the supplementary pipeline, thereby reducing the insufficient combustion of the incinerator caused by the interruption of industrial air supply.

[0010] Optionally, a pneumatic regulating valve is provided at one end of the replenishment pipeline to regulate the flow rate of gas flowing through the replenishment pipeline.

[0011] By adopting the above technical solution, the pneumatic regulating valve can dynamically adjust the opening degree according to the real-time pressure difference between the two branches: when the pressure of the second air supply branch is higher than that of the first air supply branch, the opening degree is appropriately reduced to reduce the gas flow rate through throttling and balance the pressure difference between the first and second air supply branches; when the pressure difference is reduced to a safe range, the opening degree is maintained to improve the stability of the system.

[0012] Optionally, a check valve is installed at the end of the supplementary pipeline to reduce gas backflow.

[0013] By adopting the above technical solution, the check valve effectively blocks the backflow of gas from the first gas supply branch to the second gas supply branch, ensuring that the gas flows in the predetermined direction and improving the stability and reliability of the gas supply system.

[0014] Optionally, the refrigerated dryer in the first gas supply branch is equipped with a humidity monitor, which is electrically connected to the on / off valve and is used to detect the humidity inside the refrigerated dryer.

[0015] By adopting the above technical solution, when the ambient humidity is high and the humidity inside the refrigerated dryer exceeds the standard, the monitor triggers a signal to keep the on / off valve open, so that the gas in the first gas supply branch does not pass through the refrigerated dryer, reducing the probability of increased gas moisture content and improving the flexibility of system use.

[0016] Optionally, both the first and second gas supply branches are connected to buffer tanks, and the buffer tanks are connected to the refrigerated dryer through pipelines to balance the gas pressure.

[0017] By adopting the above technical solution, the buffer tank can buffer the intake air impact, keep the gas flow and pressure entering the refrigerated dryer stable, ensure that the refrigerated dryer is always in the best dehydration condition, and reduce the probability of system damage.

[0018] Optionally, a pressure gauge is installed at one end of the connecting pipe between the buffer tank and the refrigerated dryer to detect the pressure of the gas passing through.

[0019] By adopting the above technical solution, operators can obtain the specific values ​​and changes in gas pressure in a timely manner through pressure gauge data, which facilitates operators to accurately grasp the gas pressure status in the system. When abnormal gas pressure occurs, it can be detected in time and corresponding measures can be taken to adjust it, ensuring the stable operation and gas supply safety of the gas supply system for the incineration workshop.

[0020] Optionally, filters are connected to the first and second gas supply branches. The filters are connected to the refrigerated dryer through pipelines and are used to filter impurities in the transported gas.

[0021] By adopting the above technical solution, the filter can effectively filter impurities in the transported gas. This ensures that the gas entering subsequent equipment, such as industrial air storage tanks and instrument air storage tanks, is purer, reduces wear and damage to the equipment caused by impurities, extends the service life of the equipment, and also helps to improve the stability and reliability of the gas supply system, providing a higher quality gas supply for the normal operation of the incineration plant.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During the rainy season, when the air humidity is high, the valve opens and the gas bypasses the refrigerated dryer and is transported to the industrial air storage tank through the side branch pipeline. This reduces the excessive humidity inside the refrigerated dryer, increases the gas humidity, thereby reducing wear and tear on the equipment and extending its service life. 2. The check valve effectively blocks the backflow of gas from the first gas supply branch to the second gas supply branch, ensuring that the gas flows in the predetermined direction and improving the stability and reliability of the gas supply system. 3. When the pressure in the industrial air storage tank is insufficient, the pneumatic shut-off valve can be opened instantly, allowing the gas from the second air supply branch to be quickly replenished to the first branch through the supplementary pipeline, reducing the risk of insufficient combustion in the incinerator due to interruption of industrial air supply and improving the flexibility of the equipment.

[0025] The present application will be further described in detail below with reference to all the accompanying drawings.

[0026] This application discloses a gas supply system for an incineration plant. Example

[0027] Reference Figure 1 A gas supply system for an incineration plant includes an air compressor unit, a first gas supply branch 2, and a second gas supply branch 3. The first gas supply branch 2 and the second gas supply branch 3 are respectively connected to the air compressor unit through pipelines. The air compressor unit includes several air compressors 1, which supply compressed gas to the first gas supply branch 2 and the second gas supply branch 3 respectively. The first gas supply branch 2 is connected to an industrial air storage tank 24 at its end, and the second gas supply branch 3 is connected to an instrument air storage tank 34 at its end. The gas in the industrial air storage tank 24 is used by industrial equipment, and the gas in the instrument air storage tank 34 is used by instrument equipment. The industrial air storage tank 24 can adapt to the demand for large-flow instantaneous gas consumption, while the instrument air storage tank 34 focuses on maintaining stable pressure. The independent branch design facilitates the configuration of subsequent processing units for the different requirements of the two types of gases, further optimizing gas quality and meeting differentiated gas consumption standards.

[0028] Reference Figure 1Both the first gas supply branch 2 and the second gas supply branch 3 are connected to a refrigerated dryer 21. When the gas is transported, it passes through the refrigerated dryer 21, which removes moisture from the gas. One end of the first gas supply branch 2 is connected to a bypass pipe 23, which is connected to an industrial air storage tank 24. This bypasses the refrigerated dryer 21 and supplies gas directly to the industrial air storage tank 24. One end of the first gas supply pipe is equipped with an on / off valve 22. During the rainy season, the air humidity is high, and the demand for gas from industrial equipment is high. The refrigerated dryer 21 has low operating efficiency, which results in a certain amount of water vapor inside the refrigerated dryer 21. When the gas passes through the refrigerated dryer 21, the moisture content of the gas will increase.

[0029] Reference Figure 1 The first air supply branch 2 has a humidity monitor installed in the refrigerated dryer 21. The humidity monitor is electrically connected to the on / off valve 22. The humidity monitor monitors the humidity in the refrigerated dryer 21 in real time. When the ambient humidity is high and the humidity in the refrigerated dryer 21 exceeds the standard, the humidity monitor triggers a signal to keep the on / off valve 22 open. At this time, the gas in the first air supply branch 2 does not pass through the refrigerated dryer 21, but is transported to the industrial air storage tank 24 from the side branch pipeline 23, reducing the probability of increased gas humidity, thereby reducing the damage to industrial equipment caused by excessively humid gas and extending the service life of the equipment.

[0030] Reference Figure 1 Both the first gas supply branch 2 and the second gas supply branch 3 are connected to buffer tanks 31, and buffer tanks 31 are connected to the refrigerated dryer 21 via pipelines. Buffer tanks 31 can effectively balance gas pressure. During the gas supply process, gas pressure may fluctuate due to various factors, and buffer tanks 31 can regulate these unstable pressures to avoid damage to downstream equipment caused by excessively high or low pressures. This ensures that gas is delivered to the industrial air storage tank 24 and the instrument air storage tank 34 at a stable pressure, improving the stability and reliability of the entire gas supply system and ensuring that relevant equipment in the incineration workshop can operate normally under suitable gas pressure conditions.

[0031] Reference Figure 1 A pressure gauge 32 is installed at one end of the connecting pipeline between the buffer tank 31 and the refrigerated dryer 21. The operator can obtain the specific value and changes of the gas pressure in a timely manner through the data of the pressure gauge 32, so as to make the operator accurately grasp the gas pressure status in the system. If the pressure is higher than the upper limit, the pressure can be appropriately released through the buffer tank 31; if the pressure is lower than the lower limit, the air compressor 1 can be triggered to replenish the pressure, so as to ensure that the gas pressure entering the refrigerated dryer 21 is always stable, which is conducive to improving the stable operation and gas supply safety of the gas supply system for the incineration workshop.

[0032] Reference Figure 1A pneumatic shut-off valve 41 is installed between the first gas supply branch 2 and the second gas supply branch 3. The outlet of the pneumatic shut-off valve 41 is connected to the first gas supply branch 2 through the supplementary pipeline 4, and the inlet of the pneumatic shut-off valve 41 is connected to the second gas supply branch 3 through the supplementary pipeline 4. When the pressure of the industrial air storage tank 24 is insufficient, the pneumatic shut-off valve 41 can be opened instantly, so that the gas from the second gas supply branch 3 can be quickly supplemented to the first branch through the supplementary pipeline 4. This reduces the risk of insufficient combustion in the incinerator due to interruption of industrial air supply, ensures the stability and adaptability of gas supply in the incineration workshop, and improves the operating efficiency and reliability of the entire gas supply system.

[0033] Reference Figure 1 One end of the supplementary pipeline 4 is equipped with a pneumatic regulating valve 42. The pneumatic regulating valve 42 can dynamically adjust the opening degree according to the real-time pressure difference between the two branches. When the pressure of the second gas supply branch 3 is higher than that of the first gas supply branch 2, the opening degree is appropriately reduced to reduce the gas flow rate through throttling and balance the pressure difference between the first gas supply branch 2 and the second gas supply branch 3. When the pressure difference is reduced to a safe range, the opening degree is maintained to reduce the adverse effects on the system caused by excessive or insufficient gas flow and improve the stability of the system.

[0034] Reference Figure 1 The end of the replenishment pipeline 4 is equipped with a check valve 43. When the gas flows in the replenishment pipeline 4, the check valve 43 can prevent the gas from flowing backward, ensuring that the gas is delivered in the predetermined direction, reducing the impact of gas backflow on the normal gas supply system of the incineration workshop, improving the stability and reliability of the gas supply system, and ensuring that the industrial air storage tank 24 and the instrument air storage tank 34 can continuously obtain a stable gas supply.

[0035] Reference Figure 1 A filter 33 is connected to the first gas supply branch 2 and the second gas supply branch 3. The filter 33 is connected to the refrigerated dryer 21 through a pipeline. The filter 33 can effectively filter impurities in the transported gas. This ensures that the gas entering subsequent equipment such as the industrial air storage tank 24 and the instrument air storage tank 34 is purer, reduces the wear and damage of impurities to the equipment, extends the service life of the equipment, and also helps to improve the stability and reliability of the gas supply system, providing a higher quality gas supply for the normal operation of the incineration plant.

[0036] The implementation principle of a gas supply system for an incineration plant according to an embodiment of this application is as follows: the air compressor unit provides compressed gas to the first gas supply branch 2 and the second gas supply branch 3. The first gas supply branch 2 delivers the gas to the industrial air storage tank, and the second gas supply branch 3 delivers the gas to the instrument air storage tank 34. During the gas delivery process, the refrigerated dryer 21 is used to remove moisture from the gas. When it is the rainy season, the air humidity is high, the industrial equipment has a large demand for gas, and the refrigerated dryer 21 has a low working efficiency. At this time, the on / off valve 22 is opened, and the gas from the first gas supply branch 2 is delivered to the industrial air storage tank 24 through the bypass branch pipeline 23 without passing through the refrigerated dryer 21, reducing the probability of increased gas humidity, thereby reducing the damage caused by excessively humid gas to the industrial equipment and extending the service life of the equipment.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
