[0002] Industrial kiln flue gas is a gas with a large amount of heat generated after production, which contains a large amount of dust and waste gas that needs to be treated. When treating industrial kiln flue gas, its heat and pollutants in the flue gas need to be filtered out to meet the national emission standards before being discharged.

DETAILED DESCRIPTION

[0037] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0038] Please refer to Figures 1-14As shown, an industrial kiln flue gas purification and emission equipment includes a filter pipe assembly 1, a gas flow assembly 2, a flushing flow assembly 3 and a reaction box 4, wherein the filter pipe assembly 1 is used for preliminary treatment of impurities in the kiln flue gas, realizing the dust removal and impurity removal effect of the kiln flue gas, and the gas flow assembly 2 and the flushing flow assembly 3 are arranged on the filter pipe assembly 1, the gas flow assembly 2 is used to realize the entering and discharging of the flue gas, and the flue gas is discharged from the filter pipe assembly 1 after being filtered by the filter pipe assembly 1. If the impurities in the filter pipe assembly 1 are too much to affect the filtering effect of the filter pipe assembly 1, the filter pipe assembly 1 can be backwashed by the flushing flow assembly 3. After the flushing is completed, clean gas is introduced from the gas flow assembly 2 to preliminarily dry the residual moisture in the filter pipe assembly 1, and then the filter pipe assembly 1 is used again. In the use process, the gas treated by the filter pipe assembly 1 is further treated in the reaction box 4, so that the treatment effect of the gas is better after the cooperation of various mechanisms in the present application, thereby solving the problem of preserving the heat in the flue gas and avoiding the influence of external moisture on the water content in the flue gas.

[0039] The filter pipe assembly 1 includes a first filter housing 11 and a sealing cover 12, and a filter pipe support seat 16 is fixed outside the first filter housing 11 for mounting the filter pipe assembly 1. The first filter housing 11 is connected by the sealing cover 12, and the gas flow assembly 2 and the flushing flow assembly 3 are installed on the sealing cover 12, so that the flue gas or the flushing liquid can be flushed into the inside of the first filter housing 11. A second housing 13 is fixed in the first filter housing 11, and a filter assembly is arranged in the second housing 13.

[0040] Firstly, the flue gas flowing in the filter pipe assembly 1 contains a large amount of heat, and such high temperature can cause large deformation of the steel structure building. Specifically, when the temperature is too high, it has a greater impact on the environment-friendly steel structure building. For example, the temperature of the steel structure of the filter pipe assembly 1 during work is as high as 200-300℃. Therefore, in the design process, the temperature stress and the deformation caused by the temperature should be calculated according to the actual situation of the steel structure of the filter pipe assembly 1. The temperature deformation and the temperature stress are contradictory, and the release of the temperature stress of the steel structure will cause large deformation of the structure. Reasonable control of the temperature deformation will increase the temperature stress. Therefore, both the temperature stress and the temperature deformation should be controlled to ensure the stability of the steel structure of the filter pipe assembly 1 and meet the building requirements.

[0041] For steel structure, temperature fixed point usually occurs in the middle of the structure, the temperature fixed point has strong rigidity constraint, the constraint force gradually decreases to the both ends of the structure, the temperature stress is the largest in the middle of the structure, the constraint force of the both ends of the structure is reduced, the steel frame is deformed due to the temperature, and the deformation is weakened with the weakening of the control force, so in the actual application process, the structure deformation is gradually changed from the middle to the both ends.

[0042] The force of high temperature on the structure of the filter pipe assembly 1 is symmetrically arranged, and the temperature stress release area is arranged at the middle position of the filter pipe assembly 1.

[0043] The specific structure is as follows: the second shell 13 includes a first fixed shell 131, a second fixed shell 133 and a temperature stress plate 132. First, the first fixed shell 131 and the second fixed shell 133 are fixed inside the first filter shell 11, and then the temperature stress plate 132 is installed on the first fixed shell 131 and the second fixed shell 133. A plurality of square holes 135 are formed in the first fixed shell 131, the second fixed shell 133 and the temperature stress plate 132, and the first fixed shell 131, the temperature stress plate 132 and the second fixed shell 133 are connected by fastening bolts 134.

[0044] In the present application, the square hole 135 is square and the fastening bolt 134 is circular. The width of the square hole 135 is 1mm-2mm larger than the fastening bolt 134, so the fastening bolt 134 slides along the square hole 135 under the action of temperature stress impact. Therefore, by arranging the temperature release area at the middle position of the filter pipe assembly 1, it can be seen from the ANSYS simulation that the maximum deformation of the temperature release area column is 11.236mm, and the length of the rectangular hole in the long direction should not be greater than the sum of the maximum deformation value and the diameter of the bolt. Therefore, in the present application, the length of the square hole 135 is 50mm. In the present application, the high-strength bolt M30 is selected for the fastening bolt 134, and the width of the square hole 135 is 2mm larger than the diameter of the fastening bolt 134, so the value is 32mm.

[0045] The maximum value of the longitudinal horizontal temperature load of the crane beam of the temperature stress release area is 254.5 KN, the design value of the shear bearing capacity of a single M30 high-strength bolt is 143.775 KN, the design value of the shear bearing capacity of two high-strength bolts is 287.55 KN, the shear bearing capacity of the high-strength bolt is greater than the total value of the longitudinal horizontal temperature load, and the shear strength requirement can be met. The temperature stress release area plays a good role in weakening the temperature stress, and the temperature stress of the beam in the middle of the filter tube assembly 1 is only-0.00089 MPa. The setting of the temperature stress release area plays a good role in releasing the temperature stress. Under the temperature change, the temperature stress gradually increases, and when it is greater than the shear bearing capacity of the high-strength bolt, the crane beam slips. With the decrease of the constraint of the crane beam, the temperature stress is released.

[0046] In order to realize the specific filtering effect of the filter tube assembly 1, a double-layer filtering mechanism is arranged in the application. Specifically, a first filter cylinder 14 is arranged inside the filter tube assembly 1, wherein the first filter cylinder 14 is cylindrical, and the first filter cylinder 14 is close to the second shell 13. A second filter assembly 15 is arranged inside the first filter cylinder 14. The first filter cylinder 14 is used to make the flowing gas flow freely between the first filter cylinder 14 and the second shell 13, and the first filter cylinder 14 is used to purify the flue gas. The flue gas can also be finely treated by using the second filter assembly 15. The second filter assembly 15 includes a filter body 152, wherein the filter body 152 is respectively provided with a first opening 151 and a second opening 153, and the center positions of the first opening 151 and the second opening 153 are not on the same horizontal line. Adjacent two second filter assemblies 15 are arranged symmetrically with respect to the center horizontal line, that is, the arrangement angle of adjacent second filter assemblies 15 is one hundred and eighty degrees, which can ensure that the gas entering from the second opening 153 falls on the filter body 152 of the next second filter assembly 15, and fully filters the flue gas. At the same time, the first opening 151 and the second opening 153 are also left to realize the discharge of accumulated dust.

[0047] The specific use mode includes that the gas circulation assembly 2 includes a flue gas inlet pipe 21 and a flue gas outlet pipe 22.

[0048] Wherein the flushing flow assembly 3 comprises a backwashing discharge pipe 31 and a backwashing inlet pipe 32, wherein the backwashing inlet pipe 32 and the flue gas discharge pipe 22 are on the same side, and the backwashing discharge pipe 31 and the flue gas discharge pipe 21 are on the same side, for realizing backwashing of the filter pipe assembly 1. Specifically, liquid is discharged through the backwashing inlet pipe 32, enters through the first opening 151, then the liquid backwashes the impurities on the filter body 152, and the flushed impurities are discharged through the second opening 153, and at the same time, the liquid pressure of the backwashing liquid scatters the solid impurities attached to the filter body 152, facilitating the discharge thereof, thereby realizing backwashing of the filter pipe assembly 1.

[0049] Wherein the reaction box 4 is located at the output end of the flue gas discharge pipe 22, for filtering out fine impurities in the flue gas, so in the present application, the reaction box 4 is uniformly provided with fiber filter pipes 44 inside, so that the flue gas obtained from the flue gas discharge pipe 22 is finely filtered through the fiber filter pipes 44, wherein the fiber filter pipes 44 are ceramic fiber pipes, and the flue gas is further filtered through the fiber filter pipes 44 to filter out invisible impurities, thereby obtaining further clean flue gas.

[0050] A mounting plate 42 is fixed to the side of the fiber filter pipe 44, and a gas passage 43 is formed at the middle position of the fiber filter pipe 44, wherein the first pipe 41 is fixed to the side of the mounting plate 42, and the first pipe 41 and the gas passage 43 are in communication, and the first pipe 41 is connected to the output end of the flue gas discharge pipe 22, for conveying gas into the reaction box 4 for treatment of the flue gas by the fiber filter pipe 44. The flue gas enters the gas passage 43 through the first pipe 41, and then is treated by the fiber filter pipe 44 and discharged through the second pipe 45, wherein the second pipe 45 is arranged on the reaction box 4, for discharging the filtered flue gas through the second pipe 45, realizing fine filtration of the flue gas, and obtaining relatively clean flue gas.

[0051] In order to realize the installation and support of the fiber filter pipe 44, a fiber pipe support seat 46 is arranged in the present application, and a plurality of clamping assemblies 47 are arranged on the fiber pipe support seat 46, for clamping and fixing the fiber filter pipe 44, facilitating replacement of the fiber filter pipe 44.

[0052] Specifically, the first arc base 472 is fixed on the fiber tube support seat 46, rotating seats 474 are fixed at both ends of the first arc base 472, the second arc clamping seat 471 is rotatably arranged on the rotating seat 474, the first arc base 472 and the second arc clamping seat 471 are both arc-shaped and used for clamping and fixing the fiber filter tube 44, the second arc clamping seat 471 is fixed on a rotating shaft, the rotating shaft is rotatably connected with the rotating seat 474, a driving gear is fixed on the rotating shaft, the driving gear drives a plurality of arranged meshing gears, the self-locking gear 473 is rotatably arranged on the fiber tube support seat 46, and the second arc clamping seat 471 is driven to rotate by rotating the self-locking gear 473, so that the fiber filter tube 44 is clamped by the symmetrically arranged second arc clamping seat 471, and the clamping force of the second arc clamping seat 471 is controlled and stabilized by the self-locking gear 473.

[0053] In use, first, the flue gas is discharged into the first filter housing 11 through the flue gas discharge pipeline 21, and then the flue gas is filtered by the first filter cylinder 14 and the second filter assembly 15, and then the filtered gas is discharged into the first pipeline 41 through the flue gas discharge pipeline 22, and then the flue gas is fully filtered through the fiber filter tube 44. In this process, the water content in the flue gas is filtered by various components, which can avoid the influence of external moisture on the water content in the flue gas, ensure that the water content in the flue gas does not increase, and also ensure that the heat in the flue gas does not flow away with the moisture, so as to protect the heat in the flue gas and facilitate recycling of the heat in the flue gas.

[0054] And in the specific use process, the second housing 13 is arranged outside the first filter cylinder 14, and then the square hole 135 is used, the first fixed housing 131 and the second fixed housing 133 are connected by the fastening bolt 134, and the installation of the temperature stress plate 132 is realized, so that the generated temperature stress can be released in time, the steel structure of the filter tube assembly 1 in the application is protected, and damage is avoided.

[0055] Based on the above, the application also provides a plurality of fiber filter tubes 44, which are used to treat the fine impurities in the flue gas after the flue gas is treated, further finely treat the flue gas, remove the impurities in the flue gas, and ensure the cleanliness of the discharged flue gas. The clamping assembly 47 can quickly disassemble and assemble the fiber filter tube 44, and the fiber filter tube 44 can be replaced conveniently.

[0056] When the filtering effect of the filtering pipe assembly 1 is abnormal, the application enters the flushing liquid through the backwashing inlet pipe 32, wherein the flushing liquid removes the impurities on the filtering body 152 through the first opening 151, and the flushed impurities are discharged through the second opening 153. In the application, the filtering pipe assembly 1 can be appropriately inclined to facilitate the falling of the impurities, so as to realize sufficient cleaning of the filtering pipe assembly 1.

[0057] After the flushing is completed, clean gas is introduced into the gas flow-through assembly 2 to preliminarily dry the residual moisture in the filtering pipe assembly 1, and then the filtering pipe assembly 1 is used again.

[0058] In the above process, the gas treated by the filtering pipe assembly 1 is further treated in the reaction box body 4, so that the treatment effect of the gas is better after the cooperation of the various mechanisms in the application, thereby solving the problem of preserving the heat in the flue gas in the application and avoiding the influence of external moisture on the water content in the flue gas.

[0059] As another embodiment of the application, a cleaning mechanism 5 for cleaning the dust clogging the first filter cylinder 14 is arranged between the second shell 13 and the first filter cylinder 14.

The size of the mesh holes of the first filter cylinder 14 is smaller than that of the second filter assembly 15, so that the flue gas can flow through the second filter assembly 15 for multi-stage filtering, and can be directly filtered through the first filter cylinder 14, which facilitates the filtering treatment of the flue gas. In the application, since a large amount of impurities may be adhered to the first filter cylinder 14 to clog the first filter cylinder 14, the cleaning body is slid to clean the first filter cylinder 14 by the cleaning components in the cleaning body.
