Description

Technical Field

[0001] The present invention relates to the technical field of integrated denitration, and in particular to a heat pipe type integrated denitration device with heat recovery. Background Art

[0002] In today's industrial production and energy utilization, demands for environmental protection and efficient energy use are becoming increasingly stringent. On the one hand, numerous industrial production processes generate waste gases containing pollutants such as nitrogen oxides. Direct emission of these gases can cause severe environmental pollution, disrupt ecological balance, and endanger human health. Therefore, denitrification of these waste gases is crucial. On the other hand, industrial production processes also generate significant amounts of heat. If this heat cannot be effectively recovered and utilized, it not only wastes a significant amount of energy but can also cause thermal pollution to the environment due to heat emissions.

[0003] Traditional denitrification equipment and heat recovery equipment are often independent of each other, and have problems such as large floor space, high equipment investment, high operating costs, and low energy utilization efficiency. Moreover, during the heat recovery process, it is difficult to accurately control the flow rate and flow of heat recovery. If the heat recovery flow rate is too fast, it will lead to insufficient heat recovery, reduce the heat recovery rate, and cause energy waste; if the flow rate is too slow, the equipment processing capacity cannot be fully utilized, reducing overall work efficiency. At the same time, inappropriate flow rate will also have an adverse effect on the internal components of the equipment. Excessive flow rate will produce excessive impact force on pipes, joints and other components, and long-term action may easily lead to wear, loosening or even damage of components; while too low flow rate may cause local heat accumulation, causing problems such as equipment overheating, affecting the service life of the equipment.

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the present invention provides a heat pipe type heat energy recovery and denitrification integrated equipment, which has the following beneficial effects:

[0017] 1. The heat pipe type heat recovery and denitrification integrated equipment is set up with movable components to adjust the flow rate of heat recovery. The fixed ring is fixed to the outer wall of the heat recovery machine, the turntable rotates in the fixed ring, the slide rod slides on the surface of the turntable, and the adjustment block moves with the slide rod, thereby driving the slide rod to slide inside the fixed bar. The connecting plate moves with the slide rod, causing the conduit and the internal sliding pipe to also move accordingly, changing the area of ​​the conduit to prevent the heat recovery flow rate from being too fast or too slow. Too fast a flow rate may lead to insufficient heat recovery and affect the heat recovery efficiency; too slow a flow rate may make the equipment's processing capacity unable to be fully utilized. The flow rate can be flexibly adjusted according to actual working conditions, making the heat recovery process more efficient and stable, and improving the heat recovery rate.

[0018] 2. This heat pipe type heat energy recovery and denitrification integrated equipment utilizes the setting of fixed components. After the adjustment is completed, manually release the pull on the connecting rod, so that the connecting rod will be reset through the action of the fixed spring inside the telescopic rod. When the connecting rod is reset, the penetration of the control rod will be released, so that the telescopic rod will be re-inserted into the limiting block set on the inner side of the connecting ring for positioning, thereby limiting the flow rate of heat energy recovery, avoiding excessive or insufficient heat energy recovery flow, reducing energy utilization efficiency, improving flow rate stability, and reducing operating costs.

[0019] 3. Using the alarm component, the thermometer monitors the temperature during the heat recovery process in real time. When a temperature difference occurs, the bimetallic strip deforms due to the different thermal expansion coefficients of the different metals, causing the relative positions of conductive plates 1 and 2 to change. When the temperature difference reaches a certain level, conductive plates 1 and 2 come into contact with the metal plates, completing the circuit of the alarm light. The alarm light illuminates to alert personnel, allowing them to take timely repair and adjustment measures to ensure the normal operation of the equipment, reduce losses caused by equipment failure, and improve equipment reliability and stability.

[0040] Working principle: The heat pipe type heat recovery and denitrification integrated equipment is mainly composed of a frame 1, a denitrification integrated machine 6, a heat recovery machine 2, a movable component 3, a fixed component 4 and a reminder component 5. The denitrification integrated machine 6 is responsible for denitrification of related substances, and is often combined with denitrification technologies such as selective catalytic reduction or selective non-catalytic reduction. A reducing agent is sprayed into the flue gas that has undergone heat recovery and temperature adjustment to a suitable range. Under the action of the catalyst, nitrogen oxides in the flue gas react with the reducing agent to generate nitrogen and water to remove nitrogen oxides. The reducing agent is directly sprayed into a suitable high-temperature flue gas area. The reducing agent thermally decomposes to produce active components that react with nitrogen oxides to generate nitrogen and water. The heat pipe's regulation of the flue gas temperature can ensure the temperature conditions required by the corresponding denitrification technology, helping the denitrification reaction to proceed efficiently. The heat recovery machine 2 performs heat recovery operations, using heat pipes for heat transfer. The heat pipe is filled with working fluid and is in a vacuum state. The high-temperature flue gas contacts the evaporation section of the heat pipe, causing the working medium to absorb heat and vaporize. The vaporized working medium flows to the condensation section, where it encounters cooling, releases heat and liquefies, and then flows back to the evaporation section through the wick or gravity. This cycle transfers the heat of the high-temperature flue gas to the low-temperature medium, realizing heat energy recovery and improving energy utilization. Other components regulate, limit and issue abnormal reminders for the heat energy recovery process. When it is necessary to adjust the heat energy recovery flow rate, the turntable 33 is manually rotated inside the fixed ring 31. When the turntable 33 rotates, the rectangular groove 330 on its surface will interfere with the position of the slide bar 34 on the turntable 33 and change it, so that it moves closer to the center point of the fixed ring 31. When the slide bar 34 slides, it will also drive the adjustment block 35 to swing closer to the center point of the fixed ring 31. When the adjustment block 35 swings, the flow rate of the heat flow through the conduit 39 can be adjusted. When the adjustment block 35 swings It will drive the sliding rod 36 to slide in the fixed bar 37. When the sliding rod 36 slides, it will drive the conduit 39 to slide on the surface of the sliding tube 310, thereby changing the area of ​​the conduit 39 to prevent the heat recovery flow rate from being too fast or too slow. Too fast a flow rate may lead to insufficient heat recovery and affect the heat recovery efficiency; too slow a flow rate may make the equipment processing capacity unable to be fully utilized, reducing the overall working efficiency. The flow rate can be flexibly adjusted according to the actual working conditions to make the heat recovery process more efficient and stable, improve the heat recovery rate, and adapt to different working environments and needs. Inappropriate flow rate may have an adverse effect on the internal components of the equipment. Too high a flow rate may produce excessive impact force on pipes, joints and other components, which may cause wear, loosening or even damage to components in the long run; and too low a flow rate may cause local heat accumulation, causing problems such as equipment overheating, thereby improving the service life of the equipment.

[0041] When the turntable 33 needs to be manually operated to rotate, the connecting rod 46 needs to be operated first to drive the telescopic rod 44 to retract. When the telescopic rod 44 is retracted, the positioning of the telescopic rod 44 by the connecting ring 41 will be released. When the telescopic rod 44 is retracted, the insertion rod 47 will be driven to move toward the surface close to the control rod 43 and penetrate the control rod 43. When the adjustment is completed, the pulling on the connecting rod 46 can be manually released, so that the connecting rod 46 will be reset by the action of the fixing spring 45 inside the telescopic rod 44. When the connecting rod 46 is reset, the penetration of the control rod 43 will be released, and when the telescopic rod 44 is reset, the telescopic rod 44 will be driven to extend, so that the telescopic rod 44 is re-inserted into the limiting block 42 set on the inner side of the connecting ring 41 for positioning, thereby limiting the flow rate of heat recovery, avoiding excessive or insufficient heat recovery flow, reducing energy utilization efficiency, improving flow rate stability, and reducing operating costs.

[0042] The thermometer 59 monitors the temperature during the heat recovery process in real time. When a temperature difference occurs, the bimetallic strip 56 will deform due to the different thermal expansion coefficients of different metals, and the temperature inside the operating box 51 will decrease. When the temperature decreases, the bimetallic strip 56 will change the angle of the arch, so that the bimetallic strip 56 changes the position of the conductive piece 2 58 and causes the conductive piece 1 57 to change. When the bimetallic strip 56 changes, the conductive piece 1 57 will be released from contact with the green bottom metal piece 54 of the alarm light 53, so that the green light goes out. When the bimetallic strip 56 changes, it will also interfere with the conductive piece 2 58 and the red bottom metal piece 54 of the alarm light 53, so that a red alarm is generated when the temperature is too low, so that the circuit of the alarm light 53 is turned on, and the alarm light 53 lights up to remind the staff to promptly discover abnormal temperature differences during the heat recovery process. Excessive temperature difference may indicate a failure in the heat recovery process, such as heat pipe damage, uneven heat exchange, etc. If not handled in time, it may lead to equipment performance degradation or even damage. It can quickly remind staff of abnormalities in the heat recovery process so that timely measures can be taken to repair and adjust them, ensure the normal operation of the equipment, reduce losses caused by equipment failure, and improve equipment reliability and stability.
