[0002] After garbage incineration, a large amount of polluted flue gas will be generated. These flue gases need to be treated before they can be discharged into the air to reduce the pollution of the flue gas to the air. When treating the flue gas, dry filtration is often used to purify it. The moisture present in the incinerated garbage is released by heat during the incineration process to form water vapor, making the flue gas after incineration contain moisture. When these moisture pass through the dry filtration equipment, they will adhere to the surface of the filter material, which will then make the filter material less air permeable, greatly reduce the adsorption effect of the filter material, and reduce the purification efficiency of the equipment.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0042] Example 1

[0043] Reference Figure 1-Figure 4 , a flue gas purification device for post-treatment of garbage incineration is provided, comprising a housing component 100, including a box body 101, and a cover plate 102 arranged on the top of the box body 101;

[0044] The condensation component 200 includes a contact assembly 201 disposed in the housing 101 and a fixing plate 202 disposed in the housing 101; wherein the fixing plate 202 is disposed between two groups of contact assemblies 201;

[0045] The box body 101 has an opening on the top, and the cover plate 102 corresponds to the opening. Connecting strips are fixedly provided on both sides of the opening and the cover plate 102, and the connecting strips can be fixedly connected by bolts, so that the equipment can be disassembled by loosening the bolts and the cover plate 102, which can facilitate the maintenance of the equipment. Two groups of fixing plates 202 are fixedly provided at the bottom of the box body 101, and the two groups of fixing plates 202 are fixedly connected to the inner wall of the box body 101. The two groups of fixing plates 202 are arranged between the two groups of contact components 201, and the contact components 201 and the fixing plates 202 are staggered, so that a circuitous ventilation duct is formed between the two, so that the smoke and the contact components 201 are fully in contact. Since the temperature of the contact components 201 is relatively low, the moisture in the smoke condenses after being cooled, and then the moisture in the smoke is separated, thereby reducing the moisture in the smoke and preventing the moisture from affecting the adsorption effect of the dry filter material.

[0046] Furthermore, the bottom of the box body 101 is provided with a collecting hopper 101a, a discharge port 101b provided at the bottom of the collecting hopper 101a, and an air inlet 101c and an air outlet 101d provided at both ends of the box body 101;

[0047] A collecting bucket 101a is fixedly provided at the bottom of the box 101. The collecting bucket 101a corresponds to the bottom of the contact assembly 201. The condensed water on the surface of the contact assembly 201 drops into the collecting bucket 101a and is collected by the collecting bucket 101a. The bottom of the collecting bucket 101a is connected to a discharge port 101b. When the equipment is shut down, the condensed water in the collecting bucket 101a is discharged from the equipment through the discharge port 101b. At this time, the funnel shape of the collecting bucket 101a makes it easier to discharge the condensed water. When the equipment is in use, the discharge port 101b 01b is closed to prevent smoke from overflowing from the exhaust port 101b. An air inlet 101c and an air outlet 101d are respectively provided at both ends of the box body 101. The air inlet 101c can be connected to the air inlet flue through the flange at the end, and the air outlet 101d is connected to the dry filtering device. The smoke enters the device from the air inlet 101c, and then enters the dry filtering device from the air outlet 101d. In this process, the condensation component 200 separates the moisture in the smoke, thereby reducing the moisture entering the dry filtering device.

[0048] Furthermore, the contact assembly 201 includes a baffle 201a disposed in the box body 101, a condensation chamber 201b disposed inside the baffle 201a, and a connecting pipe 201c disposed at the end of the condensation chamber 201b; wherein the fixing plate 202 is disposed between the two sets of baffles 201a, and the fixing plate 202 and the baffle 201a form a bent ventilation duct;

[0049] A baffle 201a is installed at the bottom of the box 101 through a fixing frame, and a condensation chamber 201b is provided in the baffle 201a. When the equipment is in use, the external pipe will be connected to the condensation chamber 201b, and the condensed water will flow in the condensation chamber 201b, thereby making the surface temperature of the baffle 201a lower. When the hot humid air contacts the baffle 201a, it will cool down and become condensed water, which is separated from the flue gas. The condensation chamber 201b is arranged in an "S" shape, thereby increasing the flow area of ​​the condensed water and improving the condensation effect of the baffle 201a. The collecting bucket 101a is located below the baffle 201a, and the condensed water droplets on the surface of the baffle 201a fall into the collecting bucket 101a and are collected;

[0050] Two sets of baffles 201a are provided in the box body 101. The two sets of baffles 201a are respectively close to one end of the air inlet 101c and the air outlet 101d. Two sets of fixing plates 202 are provided between the two sets of baffles 201a. The spacing between the two sets of baffles 201a is smaller than the width of the baffles 201a, so that the baffles 201a and the fixing plates 202 form a circuitous ventilation duct (such as Figure 4 As shown), the moisture in the smoke is fully in contact with the baffle 201a, thereby improving the moisture separation effect in the smoke. The diameters of the air inlet 101c and the air outlet 101d are smaller than the width of the baffle 201a, thereby further ensuring the contact between the smoke and the baffle 201a.

[0051] The baffle 201a located in the condensation chamber 201b is provided with a connecting pipe 201c. The connecting pipe 201c located at the top of the baffle 201a penetrates the top of the cover plate 102. When the cover plate 102 is installed, it can be directly put on the outside thereof, and then the connecting pipe 201c and the cover plate 102 are sealed. The connecting pipe 201c located at the bottom does not penetrate the side of the box body 101. When installing, the external pipe can be directly penetrated through the box body 101 to connect with it. After the installation is completed, the condensation pipe of the external condensation equipment is connected with the two sets of connecting pipes 201c, so that the condensed water circulates in the condensation chamber 201b, and then the surface of the baffle 201a is kept at a low temperature to separate the moisture in the flue gas;

[0052] By setting up the condensation component 200, the moisture in the flue gas is separated, the moisture content in the flue gas is reduced, and the moisture is prevented from adhering to the surface of the dry filter material, thereby ensuring the adsorption effect of the dry filter material and enabling the dry filter equipment to continuously filter the flue gas.

[0053] Example 2

[0054] During the process of the baffle 201a separating the water vapor contained in the flue gas, the condensed water on the surface of the baffle 201a will cause some dust in the flue gas to adhere to its surface. After long-term use, the large amount of dust attached to the surface of the baffle 201a will affect its heat exchange, thereby reducing the separation effect of the water vapor in the flue gas.

[0055] Reference Figure 1-Figure 8 , this embodiment is different from the first embodiment in that: it also includes a cleaning component 300, which includes a driving component 301 arranged on the cover plate 102, a follower component 302 arranged on the outside of the baffle 201a, a sliding component 303 arranged in the follower component 302, and an abutment portion 304 arranged on the outside of the baffle 201a; wherein the driving component 301 is connected to the follower component 302;

[0056] The follower component 302 is sleeved on the outside of the baffle 201a. During the use of the device, the driving component 301 drives the sliding component 303 to move along the surface of the baffle 201a through the follower component 302, and then cleans the surface of the baffle 201a. When the sliding component 303 is reset after the cleaning is completed, the sliding component 303 contacts the resistance part 304, and the resistance part 304 cleans the surface of the sliding component 303. At the same time, in the initial state, the resistance part 304 can cooperate with the follower component 302 to protect the surface of the cleaning component and avoid smoke and dust deposition on the surface of the cleaning component. The cleaning of the baffle 201a by the cleaning component ensures the separation effect of the baffle 201a on water vapor.

[0057] Furthermore, the driving assembly 301 includes a motor 301a installed on the top of the cover plate 102, a screw rod 301b provided at the output end of the motor 301a, a sliding seat 301c provided outside the screw rod 301b, and a connecting plate 301d provided on the sliding seat 301c; wherein the screw rod 301b is provided in the box body 101, and the connecting plate 301d is connected to the follower assembly 302;

[0058] A motor 301a is fixedly installed on the top of the cover 102, and a screw rod 301b is rotatably connected in the box 101. The axial end of the screw rod 301b passes through the top of the cover 102, so that the output end of the motor 301a can be connected thereto, and the motor 301a and the screw rod 301b are detachably fixedly connected, so that the connection between the motor 301a and the screw rod 301b will not affect the disassembly of the cover 102, and a sliding seat 301c is provided on the outer side of the screw rod 301b, and a connecting plate 301d is fixed on the sliding seat 301c. Since the follow-up component 302 is sleeved with the baffle 201a, it plays a limiting role, so that when the motor 301a drives the screw rod 301b to rotate, the sliding seat 301c will drive the follow-up component 302 to slide up and down through the connecting plate 301d, and then the sliding component 303 cleans the surface of the baffle 201a.

[0059] Furthermore, the follower assembly 302 includes a fixed box 302a disposed at the end of the connecting plate 301d, a cavity 302b disposed in the fixed box 302a, and a side plate 302c disposed between the two sets of fixed boxes 302a; wherein the sliding assembly 303 is disposed in the cavity 302b;

[0060] The two sides of the side plate 302c are provided with corresponding fixing boxes 302a, and the two ends of each set of fixing boxes 302a are fixed with side plates 302c, and the side plates 302c are tightly attached to the two sides of the baffle 201a. The fixing boxes 302a and the side plates 302c on both sides are combined to limit the connection plate 301d. The fixing boxes 302a are provided with cavities 302b, and the openings of the cavities 302b of the two corresponding fixing boxes 302a correspond to the surface of the baffle 201a. The sliding assembly 30 3 is arranged in the cavity 302b, and the opening allows the sliding component 303 to extend out of the fixing box 302a, and the cavity 302b can accommodate the sliding component 303. In the initial state, the sliding component 303 contacts the abutting portion 304, so that the sliding component 303 is locked in the cavity 302b, and the contact portion and the fixing box 302a form a relatively closed space, which prevents smoke and dust from accumulating on the surface of the sliding component 303, ensures the cleanliness of the surface of the sliding component 303, and has a better cleaning effect.

[0061] Furthermore, the sliding assembly 303 includes a sliding rod 303a disposed in the fixed box 302a, a scraper 303b disposed at the end of the sliding rod 303a, a spring 303c disposed on the outside of the sliding rod 303a, and a rubber pad 303d disposed on the outside of the scraper 303b; wherein the fixed box 302a is provided with a circular hole 302d corresponding to the sliding rod 303a;

[0062] The two opposite fixed boxes 302a are slidably connected to the side away from each other with multiple sets of slide bars 303a, and the scraper 303b is fixedly connected to the multiple sets of slide bars 303a on the same side. At the same time, the scraper 303b is located in the fixed box 302a, and the outer sides of the multiple sets of slide bars 303a are sleeved with springs 303c. The two ends of the spring 303c respectively contact the inner wall of the fixed box 302a and the scraper 303b. The fixed box 302a is provided with a circular hole 302d corresponding to the slide bar 303a. The top surface of the cover plate 102 is an inclined surface. The inclined surface can make the scraper 303b retract into the fixed box 302a after contacting the contact part 304. The end of the scraper 303b is a downward hook-shaped sharp corner, which can The scraper 303b can scrape off the smoke and condensed water on the surface of the baffle 201a. When the fixed box 302a is away from the resistance part 304, the spring 303c pushes the scraper 303b out of the fixed box 302a. Under the push of the spring 303c, the surface of the scraper 303b is pressed against the surface of the baffle 201a, so that during the downward movement of the fixed box 302a, the scraper 303b can clean the surface of the baffle 201a. The surface of the scraper 303b is covered with a rubber pad 303d, and the rubber pad 303d fits tightly to the surface of the scraper 303b. When the scraper 303b fits the surface of the baffle 201a, the rubber pad 303d can fit more tightly to the surface of the baffle 201a, thereby improving the cleaning effect of the scraper 303b.

[0063] Furthermore, the abutment portion 304 includes a horizontal plate 304a disposed on the outside of the baffle 201a, and a vertical plate 304b disposed on one side of the horizontal plate 304a; wherein the end of the vertical plate 304b can abut against the sliding assembly 303;

[0064] The abutment portion 304 is arranged at a higher position outside the baffle 201a, the horizontal plate 304a is fixedly arranged on the surface of the baffle 201a, and a vertical plate 304b is fixedly arranged on one side of the horizontal plate 304a. The vertical plate 304b and the baffle 201a form an "L" shape. In the initial state, the vertical plate 304b corresponds to the opening of the fixed box 302a, so that the two form a relatively closed space, preventing smoke and dust from adhering to the surface of the scraper 303b, keeping the scraper 303b clean. When b is reset after moving, the inclined surface at the top of the scraper 303b contacts the bottom end of the vertical plate 304b. Since the scraper 303b can only move horizontally when the slide bar 303a moves, the contact between the scraper 303b and the vertical plate 304b causes it to slide into the fixed box 302a. At the same time, the bottom of the vertical plate 304b cleans the top of the scraper 303b. When the fixed box 302a slides to the top, the scraper 303b is contacted by the vertical plate 304b and is completely received in the fixed box 302a.

[0065] The rest of the structure is the same as that of Example 1.

[0066] Operation process: In the initial state, the scraper 303b is located in the fixed box 302a, the vertical plate 304b closes the opening of the fixed box 302a, and the spring 303c is in a contracted state;

[0067] When the baffle 201a needs to be cleaned, the motor 301a drives the screw rod 301b to rotate. Since the fixed box 302a and the side plate 302c cooperate to limit the position, the connecting plate 301d drives the fixed box 302a to move downward when the screw rod 301b rotates. During the downward movement of the fixed box 302a, it moves away from the vertical plate 304b, and the end of the scraper 303b loses its resistance. The spring 303c pushes the scraper 303b to fit the surface of the baffle 201a. During the continuous descent of the scraper 303b, the scraper 303b scrapes off the smoke and condensed water on the surface of the baffle 201a, and then cleans the surface of the baffle 201a. After the cleaning is completed, the screw rod 301b continues to rotate, driving the fixed box 302a through the connecting plate 301d. 302a rises, and in the process of its rising, since the scraper 303b remains in contact with the baffle 201a, the top of the scraper 303b will scrape off the smoke and dust that has just adhered to the surface of the baffle 201a, and when the scraper 303b moves to collide with the bottom end of the vertical plate 304b, the bottom end of the vertical plate 304b scrapes off the smoke and dust on the top surface of the scraper 303b, and then cleans the top of the scraper 303b, so as to prevent the smoke and dust on the top of the scraper 303b from being driven to adhere to the surface of the baffle 201a when the scraper 303b cleans the baffle 201a next time, and after the fixed box 302a is completely reset, the vertical plate 304b can fit the opening of the fixed box 302a and close it, so as to keep the scraper 303b clean and prevent smoke and dust from accumulating on the scraper 303b;

[0068] By setting the cleaning component 300, the surface of the baffle 201a can be cleaned, ensuring the baffle 201a's separation effect on water vapor in the flue gas. At the same time, the scraper 303b can self-clean, ensuring the scraper 303b's cleaning effect on the baffle 201a.

[0069] Example 3

[0070] Reference Figure 1-Figure 9 , this embodiment is different from the above embodiments in that: it also includes a guide component 400, which includes a connecting column 401a, and an inclined plate 401b arranged at the end of the connecting column 401a; wherein the connecting column 401a is arranged on the baffle 201a; the inclined plate 401b is located below the baffle 201a; connecting columns 401a are fixedly provided on both sides of the baffle 201a, and the ends of the connecting columns 401a are connected to the inclined plates 401b, and the two groups of inclined plates 401b on the same group of baffles 201a are symmetrically arranged, and the inclined plates 401b are located directly below the baffle 201a. Each of the two groups of inclined plates 401b is inclined with the bottoms close and the tops away from each other. When the cleaning component 300 cleans the surface of the baffle 201a, the mixture of condensed water and smoke falls on the inclined plates 401b, and after being guided by the inclined plates 401b, falls into the collecting bucket 101a, so that the dirt cleaned by the cleaning component 300 can be better collected.

[0071] The rest of the structure is the same as that of Example 2.

[0072] Example 4

[0073] Reference Figure 1-Figure 10 This embodiment is different from the above embodiments in that: in this embodiment, the air outlet 101d of the box body 101 is connected to the air inlet end of the bag-type dust collector 500, and the flue gas enters the device through the flue. When passing through the shell part 100, the moisture in the flue gas is separated, and the flue gas continues to flow into the bag-type dust collector 500. The bag-type dust collector 500 filters the dust in the flue gas. The flue gas processed by the device can prevent the dust from adhering to the surface of the filter bag of the bag-type dust collector 500 to ensure the air permeability of the filter bag, so that the bag-type dust collector 500 can continuously filter the smoke, thereby improving the smoke treatment efficiency of the bag-type dust collector 500.

[0074] The rest of the structure is the same as that of Example 3.
