Description
Technical Field
[0001] This utility model relates to the field of flue gas preparation technology, specifically to a flue gas collection device for flue gas preparation. Background Technology
[0002] Flue gas preparation involves passing flue gas into water, where the flue gas dissolves to form flue gas water. Currently, common flue gas preparation devices pass flue gas into water through exhaust pipes. However, the flue gas is concentrated in a small area of the water body, resulting in a small contact area between the flue gas and the water body. Furthermore, the flue gas has a short residence time in the water body, leading to a short reaction time between the flue gas and the water body. As a result, most of the flue gas escapes from the water body, making flue gas preparation inefficient.
[0003] Utility model patent CN209749095U discloses a flue gas preparation device for seed germination experiments, including a straw incinerator, a reaction chamber, a water supply tank, a water collection tank, a water pump, a control module, and a detection module. The straw incinerator includes a base, a combustion chamber, a waste separation filter, a waste chamber, a filter screen, and an exhaust port; the straw incinerator is cylindrical and placed on the base; the combustion chamber and the waste chamber are integrated; the combustion chamber is located above the waste chamber; a waste separation filter is provided between the combustion chamber and the waste chamber, and the waste generated in the combustion chamber falls into the waste chamber through the waste separation filter; a movable sealing cover is provided on the top of the combustion chamber; a sealing door is provided on one side of the waste chamber for removing waste and adjusting the combustion mode; when the sealing door is fully open... The straw incinerator has a large air intake, and the straw is burned normally. When the sealed door is closed, the air intake is small, and the straw is burned by smoldering. An exhaust port is provided on the upper left side wall of the incineration chamber, and a filter screen is installed at the exhaust port. The exhaust port is connected to the reaction chamber through an air intake pipe. A water-spraying flue gas-water reaction is proposed, which increases the contact area between flue gas and water, thereby improving the efficiency of the flue gas-water reaction. In this patent, the flue gas-water reaction is achieved by spraying water, but the reaction time between flue gas and water is short, which makes the flue gas easy to escape and reduces the efficiency of the flue gas-water reaction. Utility Model Content
[0004] The main purpose of this utility model is to provide a flue gas collection device for flue gas preparation, which solves the problems of small contact area between flue gas and water and short reaction time in existing flue gas preparation devices.
[0005] To achieve the above objectives, this utility model provides a flue gas collection device for flue gas preparation, including a flue pipe, and further comprising:

[0007] The smoke exhaust assembly includes multiple smoke components connected to the smoke exhaust pipe; each smoke component is inserted into the bottom of the collection tank and has a smoke outlet hole, and the inner diameter of the smoke component is smaller than the inner diameter of the smoke exhaust pipe to disperse the smoke into the collection tank, thereby increasing the contact area between the smoke and the water in the collection tank; the smoke discharged from the smoke component moves upward and moves along the smoke baffle and then upward through the smoke exhaust duct to increase the contact time between the smoke and the water in the collection tank.
[0008] As a further improvement of this utility model, the smoke baffle includes a smoke baffle plate fixedly disposed in the collection trough; a gap is left between the smoke baffle plate and the collection trough to form a smoke exhaust duct, and adjacent smoke exhaust ducts are staggered from top to bottom.
[0009] As a further improvement of this utility model, the smoke-blocking component includes a smoke-blocking net fixedly installed in the collection trough; multiple sets of smoke-blocking nets are arranged at intervals from top to bottom, and the smoke-blocking nets are located above the smoke-blocking plate; the smoke exhaust holes are arranged at intervals on the smoke-blocking nets, and there is a gap between the axes of the smoke exhaust holes on adjacent smoke-blocking nets.

[0013] The beneficial effects of this utility model are reflected in:
[0014] By setting up multi-component smoke components with an inner diameter smaller than the exhaust pipe, the flue gas is dispersed in the water within the collection tank, increasing the contact area between the flue gas and the water. The smoke-blocking and smoke-catching components further increase the residence time of the flue gas in the water, allowing for a full reaction between the flue gas and the water, thus improving the collection efficiency. The water mist adhering to the collecting components and exhaust pipe then comes into contact with the gas discharged from the water, further collecting the flue gas. Through the combined effects of multiple layers of smoke-blocking and smoke-catching components, as well as the collecting hopper and exhaust pipe, the flue gas discharged from the exhaust pipe fully reacts with the water, improving the efficiency of flue gas water preparation.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] In one embodiment, see Figure 1 The present invention provides a flue gas collection device for flue gas preparation, comprising a flue pipe 1, a flue gas collection component, and a flue gas exhaust component.
[0021] The flue gas collection assembly includes a collection tank 2, smoke baffles 3 arranged at intervals from top to bottom within the collection tank 2, and smoke blocking components 4 positioned above the smoke baffles 3. A converging component 5 is located at the top of the collection tank 2. A liquid filling pipe 6 and a liquid drain pipe 7 are respectively provided on the collection tank 2. An exhaust pipe 8 is provided on the converging component 5. Exhaust ducts 9 are arranged at intervals and in an alternating manner on the smoke baffles 3. Exhaust holes 10 are provided on the smoke blocking components 4. The exhaust assembly includes a multi-component smoke component 11 connected to the exhaust pipe 1. The smoke component 11 is inserted into the bottom of the collection tank 2 and has an exhaust hole 12. The inner diameter of the smoke component 11 is smaller than the inner diameter of the exhaust pipe 1 to disperse the flue gas into the collection tank 2, thereby increasing the contact area between the flue gas and the water in the collection tank 2. The flue gas discharged from the smoke component 11 moves upward and then moves along the smoke baffles 3 and upward through the exhaust duct 9, thereby increasing the contact time between the flue gas and the water in the collection tank 2.
[0022] It should be noted that valves 13 are respectively installed on the liquid addition pipe 6 and the liquid discharge pipe 7.
[0023] Further, see Figure 2 The smoke baffle 3 includes a smoke baffle plate fixedly installed in the collection tank 2. A gap is left between the smoke baffle plate and the collection tank 2 to form a smoke exhaust duct 9. Adjacent smoke exhaust ducts 9 are staggered from top to bottom.
[0024] Preferably, the collecting trough 2 is a hollow rectangular body with one end open, and the two ends of the smoke baffle are fixedly connected to the inner wall of the collecting trough 2.
[0025] For example, three layers of smoke baffles (upper, middle, and lower layers from top to bottom) are installed in the collection tank 2. The number of smoke baffles in each layer is unlimited. The gaps between each layer of smoke baffles or the gaps between the smoke baffles and the inner wall of the collection tank 2 form the exhaust ducts 9. For example, two sets of bottom smoke baffles are installed at intervals. The two ends of the two sets of bottom smoke baffles are fixedly connected to the long side wall of the collection tank 2, and the side wall of the bottom smoke baffles is connected to the short side wall of the collection tank 2 at intervals. There are three exhaust ducts 9 between the two sets of bottom smoke baffles and the collection tank 2 (located on both sides of the short side of the collection tank 2 and in the middle of the collection tank 2, respectively). Three sets of middle smoke baffles are installed accordingly. Two sets of middle smoke baffles are fixedly connected to the short side of the collection tank 2 to cover the two exhaust ducts 9 from the bottom smoke baffles and the side wall of the collection tank 2. The remaining set of middle-layer smoke baffles is located in the middle of the collection tank 2, blocking the exhaust duct 9 formed between the bottom smoke baffles in the middle of the collection tank 2. At this time, there are two sets of exhaust ducts 9 on the middle-layer smoke baffles, which are located above the middle of the bottom smoke baffles. This makes the two sets of exhaust ducts 9 on the middle-layer smoke baffles and the three sets of exhaust ducts 9 on the bottom smoke baffles staggered. After the flue gas enters below the bottom smoke baffles, the flue gas moves upward along the exhaust channel on the bottom smoke baffles and then moves upward through the exhaust ducts 9 on the middle smoke baffles, thereby increasing the upward movement distance of the flue gas and increasing the contact reaction time between the flue gas and the water in the collection tank 2. The upper smoke baffles are set in the same way as the bottom smoke baffles, which can block the exhaust channel on the middle smoke baffles to increase the movement distance of the flue gas in the water.
[0026] Further, see Figure 2 The smoke-blocking component 4 includes a smoke-blocking net fixedly installed in the collection tank 2. Multiple sets of smoke-blocking nets are arranged at intervals from top to bottom. The smoke-blocking nets are located above the smoke-blocking plate. Smoke exhaust holes 10 are arranged at intervals on the smoke-blocking nets, and there is a gap between the axes of the smoke exhaust holes 10 on adjacent smoke-blocking nets.
[0027] Preferably, the smoke-blocking net is a cross-shaped net, consisting of horizontal and vertical wires. Adjacent horizontal or vertical wires are spaced apart to form smoke exhaust holes 10. The projections of the upper horizontal and vertical wires on the horizontal plane are located between the lower horizontal and vertical wires, respectively. After the flue gas escapes from the exhaust duct 9, it rises and comes into contact with the smoke-blocking net, so that the flue gas can only flow through the smoke exhaust holes 10. Under the interception of the smoke-blocking net, the flue gas is dispersed and discharged from different smoke exhaust holes 10. After the flue gas is discharged from the lower smoke-blocking net, it enters the upper smoke-blocking net. When passing through the smoke exhaust holes 10 on the upper smoke-blocking net, the flow path of the flue gas is changed because the upper smoke exhaust holes 10 and the lower smoke exhaust holes 10 are staggered, which further increases the contact area and residence time of the flue gas and the water, making it easier for the flue gas and the water to react more fully.
[0028] In the above setup, the flue gas is dispersed in the water body within the collection tank 2 by various staggered smoke baffles. As the flue gas moves along the smoke baffles and rises from the exhaust duct 9, the contact area and contact time between the flue gas and the water body are increased. Furthermore, the flue gas is further intercepted by the smoke-blocking net, increasing the residence time of the flue gas in the water body and the contact area with the water body, thereby improving the collection rate of the flue gas by the water body.
[0029] Further, see Figure 2 The collecting component 5 includes a collecting hopper 501, the inner diameter of which decreases from the end connected to the collecting trough 2 toward the end facing the exhaust pipe 8.
[0030] Preferably, the collecting hopper 501 has a funnel-shaped structure. During the upward movement of gas in the collecting tank 2, the gas comes into contact with the inner wall of the collecting hopper 501 and is discharged along the exhaust pipe 8.
[0031] In the above configuration, a small portion of the flue gas escaping through the exhaust port 10 moves upward and comes into contact with the inner wall of the collecting hopper 501. Since the flue gas carries its own heat, the flue gas enters the water body, causing the water to evaporate and adhere to the inner wall of the collecting hopper 501. A small amount of flue gas comes into contact with the water mist adhering to the collecting hopper 501, causing the flue gas and water mist to react further and collect the flue gas. The steam collected on the collecting hopper 501 flows into the collecting tank 2.
[0032] Further, see Figure 2 The exhaust pipe 8 includes an exhaust section 801 and a collection section 802 connected to the exhaust section 801. One end of the exhaust section 801 is connected to the collecting hopper 501, and the other end is connected to the collection section 802. The collection section 802 is an arc-shaped bend. The plane at the bottom of the collection section 802 is lower than the plane at the connection between the exhaust section 801 and the collecting hopper 501. The bottom of the collection section 802 is provided with a return pipe 14 connected to the collection trough 2.
[0033] Preferably, the exhaust section 801 is vertically arranged at the top of the collecting hopper 501, the collecting section 802 is a "U" shaped pipe, and the return pipe 14 passes through the collecting hopper 501, is inserted into the collecting trough 2, and is located in the flue water.
[0034] In the above configuration, the flue gas content in the gas moving upward along the collecting hopper 501 is greatly reduced. The gas discharged from the collecting hopper 501 enters the exhaust section 801 and then enters the collecting section 802. Since the collecting section 802 is an arc-shaped bend, the discharged gas is in full contact with the inner wall of the collecting section 802. Water vapor adhering to the inner wall of the collecting section 802 is collected and enters the manifold along the bottom end of the collecting section 802, and finally flows into the collecting tank 2.
[0035] Further, see Figure 2The smoke distribution component 11 includes a main smoke distribution pipe 1101 connected to the exhaust pipe 1 and a secondary smoke distribution pipe 1102 connected to the main smoke distribution pipe 1101. The main smoke distribution pipe 1101 is located outside the collection tank 2. The secondary smoke distribution pipe 1102 is provided with multiple sets that penetrate into the collection tank 2 and are located below the lowest smoke baffle. There is a gap between the end of the secondary smoke distribution pipe 1102 away from the main smoke distribution pipe 1101 and the exhaust duct 9, so as to increase the distance that the flue gas moves to the exhaust duct 9 and increase the time that the flue gas stays in the water.
[0036] Preferably, the main smoke distribution pipe 1101 is U-shaped and surrounds the outside of the collection tank 2, and the secondary smoke distribution pipe 1102 is inserted into the collection tank 2 from the short side section of the collection tank 2, with the end of the secondary smoke distribution pipe 1102 contacting the bottom end of the collection tank 2.
[0037] In the above configuration, multiple sets of flue gas distribution sub-pipes 1102 are arranged at intervals, and their inner diameters are smaller than those of the main flue gas distribution pipe 1101 and the exhaust pipe 1. The flue gas entering the main flue gas distribution pipe 1101 through the exhaust pipe 1 is dispersed into the flue gas distribution sub-pipes 1102. The multiple sets of flue gas distribution sub-pipes 1102 simultaneously discharge flue gas into the collection tank 2, so that the flue gas is dispersed in the collection tank 2, increasing the contact area between the flue gas and the water in the collection tank 2, and improving the reaction and collection efficiency of the flue gas and the water.
[0038] In this embodiment, flue gas enters the main flue gas distribution pipe 1101 through the exhaust pipe 1, and is dispersed into the water in the collection tank 2 through the secondary flue gas distribution pipe 1102. Under the action of the secondary flue gas distribution pipe 1102, the flue gas is dispersed and comes into contact with the water, increasing the contact area between the flue gas and the water. After part of the flue gas discharged from the secondary flue gas distribution pipe 1102 reacts with the water, part of it moves along the baffle plate and moves up from the exhaust duct 9 into the area below the baffle plate of the next layer, reacts with the water again, and moves up along the baffle plate. After being blocked by multiple layers of baffle plates, the contact area between the flue gas and the water increases. The increased travel distance of flue gas within the water body enhances the reaction time between the flue gas and the water, allowing the water to fully absorb the flue gas. Flue gas that has completely passed through the baffle plate rises and is blocked and diverted again upon contact with the smoke-blocking net, resulting in a larger contact area and reaction time for the remaining flue gas with the water body, thus improving flue gas collection efficiency. The gas escaping from the water body contains extremely low levels of flue gas. The rising gas further reacts with the steam adhering to the collecting hopper 501 and the exhaust pipe, resulting in low flue gas content in the discharged gas and improving flue gas preparation efficiency.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
