Description

Technical Field

[0001] This utility model belongs to the technical field of flue gas analyzers, and specifically relates to a cooling and filtering device for a flue gas analyzer. Background Technology

[0002] In the current situation, factories generate large amounts of harmful flue gas during large-scale combustion operations. If this flue gas is not properly treated, it will escape into the air and cause serious environmental damage. As the country places increasing emphasis on environmental protection, standards for enterprise emissions are becoming increasingly stringent. To ensure that emissions meet environmental standards, enterprises must use flue gas analyzers to test the gas composition before emitting emissions.

[0003] However, currently used flue gas analyzers lack dedicated filtration devices, often resulting in clogging by solid particles in the flue gas during practical applications. While the filter assembly is designed to remove solid particles, some particles remain on the filter screen, causing an accumulation of impurities inside. This accumulation not only reduces the efficiency of flue gas flow but may also further lead to inaccurate instrument measurements, affecting the reliability of emission quality testing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cooling and filtering device for a flue gas analyzer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cooling and filtration device for a flue gas analyzer includes an analyzer body. A gas inlet pipe is fixedly connected to the sample inlet of the analyzer body, and an air inlet suction pipe is vertically fixedly connected to the other end of the gas inlet pipe. A suction pump is fixedly connected to the gas inlet pipe. A filter element is inserted and connected to the bottom end of the air inlet suction pipe. The filter element includes a filter cylinder. A tube is vertically fixedly connected to the top end of the filter cylinder and is inserted and connected to the air inlet suction pipe. The bottom end of the filter cylinder is open, and a ash storage screw box is threaded onto the filter cylinder. A rubber tube is vertically fixed to the inner wall of the filter cylinder, and a filter screen cylinder is vertically fixedly connected to the top end of the rubber tube. A rotating rod is vertically rotatably connected to the center of the ash storage screw box, and a scraper frame is vertically fixed to one side of the outer wall of the rotating rod. The scraper frame presses against the inner wall of the filter screen cylinder. A cooling element is connected to one side of the filter cylinder.

[0006] Furthermore, multiple springs are evenly and horizontally fixed on the outer wall of the filter cylinder, and the other end of each spring is fixed to the inner wall of the filter cylinder.

[0007] Furthermore, a chain head is rotatably connected to one side of the outer wall of the rotating rod, and multiple chain heads are arranged along the height direction of the rotating rod.

[0008] Furthermore, a cleaning motor is vertically fixed on the bottom surface of the ash storage screw box, and the output end of the cleaning motor is fixed at the bottom of the rotating rod.

[0009] Furthermore, the cooling component includes an air inlet cylinder with an opening at the bottom. The lower part of the air inlet cylinder is connected to the filter cartridge via a flexible hose, and an air inlet pipe is fixedly connected to the top of the air inlet cylinder. The air inlet pipe is used to guide flue gas into the air inlet cylinder.

[0010] Furthermore, a coolant cylinder is fitted on the outer wall of the air intake cylinder, and multiple cooling boxes are integrally connected to the inner wall of the coolant cylinder. The multiple cooling boxes are inserted into the interior of the air intake cylinder, and liquid guide pipes are symmetrically connected and fixed on the outer wall of the coolant cylinder, and the liquid guide pipes are used to guide the coolant to flow inside the coolant cylinder.

[0011] Furthermore, a collection cylinder is threaded onto the bottom end of the air intake cylinder, and the collection cylinder is used to collect condensate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The intake pipe guides the flue gas into the analysis system; the filter element's insert and filter cartridge initially remove large particulate impurities from the flue gas; the cooling element connects to the coolant pipeline via the intake pipe and liquid guide pipe, effectively reducing the flue gas temperature and condensing water vapor; the filter screen inside the filter cartridge further filters out fine impurities, and the design of the rubber tube and spring allows the filter screen to vibrate during operation, thereby removing impurities from its inner wall; the ash collection screw box and cleaning motor are used to collect and remove impurities generated during the filtration process. First, the intake pipe guides the flue gas into the cooling element, where it is cooled and condensed into water vapor by the coolant in the coolant tank. The cooled flue gas then enters the filter element's filter cartridge for further filtration by the filter screen. Subsequently, the cleaning motor inside the ash collection screw box starts, driving the scraper frame to remove impurities from the inner wall of the filter screen. The vibration caused by the spring dissipates the vibration, causing impurities from both the inner and outer walls of the filter screen to fall into the ash collection screw box, ensuring the purity of the gas used in the analyzer and improving the accuracy of the analysis results.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] refer to Figures 1-5 As shown, a cooling and filtration device for a flue gas analyzer includes an analyzer body 1. A gas inlet pipe 2 is fixedly connected to the sample inlet port of the analyzer body 1, and an air inlet suction pipe 3 is vertically fixedly connected to the other end of the gas inlet pipe 2. A suction pump 4 is fixedly connected to the gas inlet suction pipe 2. A filter element 5 is inserted and connected to the bottom end of the air inlet suction pipe 3. The filter element 5 includes a filter cartridge 51, and a sleeve 52 is vertically fixedly connected to the top end of the filter cartridge 51. The sleeve 52 is inserted and connected to the air inlet suction pipe 3. The bottom end of the filter cartridge 51 is open, and a screw ash storage box 56 is threaded onto the filter cartridge 51. A rubber tube 53 is vertically fixed to the inner wall of the analyzer 1, and a filter screen cylinder 54 is vertically connected and fixed to the top of the rubber tube 53. A rotating rod 57 is vertically rotatably connected to the center of the ash storage screw box 56, and a scraper frame 58 is vertically fixed to one side of the outer wall of the rotating rod 57. The scraper frame 58 presses against the inner wall of the filter screen cylinder 54. A cooling element 6 is connected to one side of the filter cylinder 51. The analyzer body 1 is responsible for analyzing the flue gas. The air guide pipe 2 is used to guide the flue gas into the system. The air intake pipe 3 and the suction pump 4 work together to draw the external flue gas into the system through the air intake pipe 3 by the suction of the suction pump 4. The filter cylinder 51 in the filter element 5 can prevent particulate matter from entering the analyzer body 1, and the internal filter screen cylinder 54 filters fine particulate matter. The rubber tube 53 ensures smooth airflow. The ash collection screw box 56 is used to collect the filtered ash. The rotating rod 57 and scraper frame 58 allow the user to easily clean the ash on the filter screen cylinder 54 by rotating the rotating rod 57 on the ash collection screw box 56, which in turn rotates the scraper frame 58, maintaining the filtration effect. The cooling component 6 cools the high-temperature flue gas before it enters the analyzer body 1, protecting the sensitivity and service life of the analyzer body 1. First, the external flue gas is introduced into the system through the intake pipe 3 and the suction pump 4. The cooling component 6 cools the flue gas, and then it is filtered by the filter screen cylinder 54 in the filter component 5 before being sent to the analyzer body 1 for accurate analysis.

[0017] refer to Figure 4 As shown, multiple springs 55 are evenly and horizontally fixed on the outer wall of the filter cylinder 54, and the other end of each spring 55 is fixed to the inner wall of the filter cylinder 51. A chain head 59 is rotatably connected to one side of the outer wall of the rotating rod 57, and multiple chain heads 59 are arranged along the height direction of the rotating rod 57. A cleaning motor 561 is vertically fixed on the bottom surface of the ash storage screw box 56, and the output end of the cleaning motor 561 is fixed to the bottom end of the rotating rod 57. The multiple springs 55 evenly and horizontally fixed on the outer wall of the filter cylinder 54 primarily function to ensure slight vibration of the filter cylinder during operation through the elasticity of the springs 55, thereby helping to improve filtration efficiency and effect, and preventing the filter cylinder 54 from clogging due to dust accumulation after prolonged use. The other ends of these springs 55 are fixed to the inner wall of the filter cylinder 51, serving to support and position the springs 55, allowing the springs 55 to apply a uniform vibration effect to the filter cylinder 54. The rotating rod 57 is connected to the cleaning chain via a chain head 59. The chain head 59 is positioned at multiple points along the height of the rotating rod 57, enabling the entire device to perform periodic cleaning actions during rotation. A cleaning motor 561, fixed to the bottom of the ash collection screw box 56, provides power to the rotating rod 57. Driven by the cleaning motor 561, the rotating rod 57 rotates along a fixed axis, thereby driving the chain head 59 and the entire device in a circular motion, achieving effective cleaning and maintenance of the filter cylinder 54 and the inner wall of the filter cartridge 51. This device, through the vibration provided by the spring 55 and the mechanical motion driven by the cleaning motor, achieves continuous cleaning of the filter cylinder 54, effectively preventing a decrease in filtration efficiency due to dust accumulation and maintaining the system's high-efficiency operation.

[0018] refer to Figure 4 and Figure 5As shown, the cooling component 6 includes an air inlet cylinder 61 with an opening at its bottom. The lower part of the air inlet cylinder 61 is connected to the filter cartridge 51 via a flexible hose, and the top of the air inlet cylinder 61 is connected and fixed with an air inlet pipe 62, which guides the flue gas into the air inlet cylinder 61. A coolant cylinder 63 is fitted onto the outer wall of the air inlet cylinder 61, and multiple cooling boxes are integrally connected to the inner wall of the coolant cylinder 63. These cooling boxes are inserted into the interior of the air inlet cylinder 61. A liquid guide pipe 64 is symmetrically connected and fixed to the outer wall of the coolant cylinder 63, which guides the coolant to flow inside the coolant cylinder 63. A collection cylinder 65 is threaded onto the bottom end of the air inlet cylinder 61, which collects condensate. The air inlet pipe 62 guides the pre-filtered flue gas into the next process. The air inlet cylinder 61 receives and pre-guides the flue gas into the system. The air inlet cylinder 61 is connected to the filter cartridge 51 via a flexible hose to ensure that the flue gas can be effectively filtered. The coolant cylinder 63, fitted onto the outer wall, is in close contact with the intake cylinder 61 via an internal cooling box. The flow of coolant cools the flue gas, effectively reducing its temperature. The coolant cylinder 63 is connected to an external circulation system via a guide pipe 64, enabling coolant recycling and reducing energy consumption. A collection cylinder 65 is installed at the bottom of the intake cylinder 61 to collect condensate, ensuring the system's dryness and effectiveness. After entering the intake cylinder 61 through the intake pipe 62, the flue gas comes into contact with the external coolant cylinder 63. The flow of coolant carries away the heat from the flue gas, cooling it. The condensed water is collected by the collection cylinder 65, thus achieving flue gas cooling and water recovery, improving the overall system efficiency and environmental performance.

[0019] The working principle of this utility model is as follows: First, when analyzing the gas after combustion, the air inlet pipe 3 of the analyzer body 1 is inserted into the insert 52 of the filter cartridge 51 of the filter element 5. The air inlet pipe 62 at the top of the air inlet cylinder 61 in the cooling element 6 is inserted into the flue gas discharge pipe to collect the flue gas. The suction pump 4 on the air guide pipe 2 is started to draw the flue gas into the air inlet pipe 62. Then, the coolant pipe 64 of the coolant cylinder 63 outside the air inlet cylinder 61 of the cooling component 6 circulates with the coolant pipe. The flue gas enters the air inlet cylinder 61 of the cooling component 6 and comes into contact with multiple cooling boxes in the coolant cylinder 63. The heat of the flue gas is transferred to the coolant in the coolant cylinder 63 to cool the flue gas. The flue gas is cooled down to facilitate subsequent detection. At the same time, the water vapor in the flue gas condenses and flows down into the collection cylinder 65 for storage. The cooled flue gas enters the filter element 5. Finally, the flue gas enters the filter cartridge 51 and is filtered through the filter screen 54 to remove impurities. The filtered gas is then guided into the analyzer body 1 through the gas guide pipe 2. To ensure that the inner wall of the filter screen 54 is free of impurities, the cleaning motor 561 at the bottom of the ash storage screw box 56 is started, which drives the rotating rod 57 to rotate in the ash storage screw box 56. This drives the scraper frame 58 to scrape off the impurities adhering to the inner wall of the filter screen 54. Then, the rotating rod 57 drives the chain head 59 to strike the filter screen 54, causing the spring 55 on the outer wall of the filter screen 54 to deform. This causes the filter screen 54 to shake on the rubber tube 53, shaking off the impurities adhering to the inner wall of the filter screen 54. The impurities fall into the ash storage screw box 56.

[0020] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
