Description

Technical Field

[0001] The invention relates to the technical field of waste gas recovery, and in particular to a printing and dyeing waste gas treatment device with heat recovery and utilization. Background Art

[0002] In the textile industry, the printing and dyeing setting machine is the main processing equipment and also one of the energy-consuming equipment. It is a device that uses heated air to dry and set the fabric. Generally, the hot air temperature required by the setting machine is around 200°C, and the exhaust gas temperature of the setting machine is also around 170°C, which contains rich thermal energy.

[0003] At present, the waste gas generated by printing and dyeing in the textile industry is usually discharged directly. The direct discharge method greatly wastes the heat energy in the waste gas. Therefore, how to recycle and fully utilize the heat energy in the waste gas is an urgent problem that needs to be solved. At the same time, the waste gas is mostly harmful gases with hydrogen sulfide, carbon disulfide, and sulfur dioxide as the main gas components. When discharged, it needs to be filtered and purified through filter elements made of activated carbon and other materials before it can be discharged into the air. After a long period of purification and adsorption work, the filter element needs to be replaced or cleaned. The existing measure is to remove the filter element from the equipment for cleaning or replacement. The whole process requires shutdown for operation, which makes the operation time-consuming and labor-intensive, and the shutdown operation seriously delays work efficiency. Summary of the invention

[0034] 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.

[0035] Example

[0036] Reference Figures 1 to 10 , is an embodiment of the present invention, comprising a printing and dyeing waste gas treatment device with heat recovery, comprising,

[0037] The recovery unit 100 includes a box body 101 located outside, a receiving component 102 arranged at one side of the box body 101, a large spiral heat release tube 103 spirally coiled and arranged in the receiving component 102, a small spiral heat release tube 104 vertically arranged at the center of the large spiral heat release tube 103, and the end of the small spiral heat release tube 104 extends to the outside of the receiving component 102, and a switching component 105 arranged at the end of the large spiral heat release tube 103, and the other end of the small spiral heat release tube 104 is connected to one side of the switching component 105, and one side end of the switching component 105 extends to the outside of the receiving component 102;

[0038] The filter unit 200 includes a first fixing component 201 fixedly arranged on one side of the outside of the accommodating component 102, a second fixing component 202 symmetrically arranged with the first fixing component 201, a support plate 203 located between the second fixing component 202 and the first fixing component 201, and the support plate 203 is in the shape of a half-cylindrical sheet and is laterally plugged into a connecting component 204 on the upper side of the first fixing component 201, and the switching component 105 and the end of the small spiral heat release tube 104 are connected to the connecting component 204, and a filter component 205 laterally arranged between the second fixing component 202 and the first fixing component 201, and the support plate 203 is supported below the filter component 205; and,

[0039] The switching unit 300 includes a fixing component 301 which is laterally arranged at the position of the second fixing component 202, a pushing component 302 which is laterally inserted into the fixing component 301, and the outer end of the pushing component 302 extends outward to the outside of the second fixing component 202, a switching component 303 which is slidably connected to the fixing component 301, and the top of the switching component 303 abuts against the end of the pushing component 302, a hexagonal prism 304 which is laterally inserted into the axial position of the switching component 303, and the two ends of the hexagonal prism 304 extend outward to the second fixing component 202 and the filtering component 205 respectively, and a return spring 305 which is sleeved on the hexagonal prism 304, and one end of the return spring 305 abuts against the bottom of the switching component 303.

[0040] Among them, combined Figure 2 The accommodating component 102 includes a water tank 1021 located in the box body 101, a water tank 1022 opened inside the water tank 1021, and the large spiral heat release tube 103 and the small spiral heat release tube 104 are both arranged in the water tank 1022, and a water outlet pipe 1023 connected to the end of the water tank 1022, and one end of the water outlet pipe 1023 extends to the outside of the box body 101.

[0041] During use, a water inlet is provided at the top of the water tank 1021, and the outer end of the water inlet is connected to a water pump. When in use, the water tank 1022 is filled with water, and the heat in the exhaust gas is used to heat the water flow through the large spiral heat release tube 103 and the small spiral heat release tube 104, thereby realizing the recovery and utilization of the exhaust gas heat.

[0042] Further, combined with Figure 2 The large spiral heat release tube 103 is a spiral structure as a whole and is evenly distributed in the water tank 1022. The spiral structure can increase the contact area with the water flow in the water tank 1022, thereby releasing heat better and more fully and accelerating the heat recovery efficiency. The small spiral heat release tube 104 is erected at the winding center of the large spiral heat release tube 103, and can release the heat of the secondary circulating exhaust gas in the same way as the large spiral heat release tube 103.

[0043] Among them, combined Figure 3 The switching component 105 includes a three-way joint 1051 connected to one end of the small spiral heat release tube 104, a connecting groove 1052 opened inside the three-way joint 1051, a first connecting tube 1053 connected between the three-way joint 1051 and the end of the large spiral heat release tube 103, a second connecting tube 1054 arranged on one side of the three-way joint 1051, and the second connecting tube 1054 is connected to the connecting component 204, a conversion block 1055 arranged in the connecting groove 1052, a limiting ring 1056 arranged in the first connecting tube 1053, and an expansion medium 1057 arranged between the limiting ring 1056 and the first connecting tube 1053.

[0044] During use, the first connecting tube 1053 is connected to the end of the large spiral heat-releasing tube 103, and the second connecting tube 1054 is connected to the filter unit 200. The expansion medium 1057 is made of a spiral heat-absorbing material. When subjected to a certain amount of heat, it will expand according to the principle of thermal expansion and contraction. The expanded expansion medium 1057 will increase its own area, and then push the conversion block 1055 at the other end, so that the conversion block 1055 can be displaced and slid in the connecting groove 1052. The limiting ring 1056 is a circular ring structure, which will not hinder the normal transportation connection inside the first connecting tube 1053.

[0045] Further, combined with Figure 3 A z-shaped channel 1058 of a z-shaped structure is opened inside the conversion block 1055, a top connecting port 1059 connected to the first connecting pipe 1053 is opened at the top of the z-shaped structure, a lower connecting port 10510 is opened on the outer side of the lower end, and an upper connecting port 10511 is opened on the outer side of the upper end.

[0046] During use, combine Figure 3 , when the conversion block 1055 is not pushed by the expansion medium 1057, the lower connecting port 10510 remains connected with the second connecting pipe 1054, while the upper connecting port 10511 is attached to the inner wall of the connecting groove 1052 and is not connected to the outside. At this time, the low-temperature exhaust gas after the large spiral heat release pipe 103 absorbs heat can enter the Z-shaped channel 1058 through the first connecting pipe 1053 and the top connecting port 1059, and then is transported into the second connecting pipe 1054 through the lower connecting port 10510 on the side of the Z-shaped channel 1058, and finally is transported to the filter unit 200 for filtration through the second connecting pipe 1054; when the exhaust gas transported by the large spiral heat release pipe 103 still contains a large amount of heat energy, the exhaust gas temperature at this time is too high, which will cause the expansion medium 1057 to expand due to heat, thereby pushing the conversion block 1055 in the connecting groove 1052. The large spiral heat release tube 104 then moves inside, and the lower connecting port 10510 will be misaligned with the second connecting tube 1054, so that the two are no longer connected, while the upper connecting port 10511 will be connected to the small spiral heat release tube 104. At this time, the waste gas with heat in the large spiral heat release tube 103 will be transported to the Z-shaped channel 1058 via the first connecting tube 1053 and the top connecting port 1059, and then transported to the small spiral heat release tube 104 via the upper connecting port 10511 on the side of the Z-shaped channel 1058, and then assisted by the small spiral heat release tube 104 for secondary waste gas heat energy recovery. By performing double recovery operation on the waste gas heat, it can be ensured that the heat inside the waste gas can be fully recovered, and energy waste can be effectively avoided. Finally, the waste gas that has absorbed all the heat will be transported into the filter unit 200 through the end of the small spiral heat release tube 104 for filtration and purification.

[0047] Among them, combined Figure 5The first fixed component 201 includes a left fixed disk 2011 whose outer side is recessed inward, and one end of the filter component 205 extends into the outer recess of the left fixed disk 2011, and filter holes 2012 and a discharge port 2013 are symmetrically opened on the left fixed disk 2011 and are symmetrical in the upper and lower directions, and the outer end of the connecting component 204 is installed in the discharge port 2013.

[0048] Among them, combined Figure 6 The second fixed component 202 includes a right fixed plate 2021 covering the outer end of the filter component 205, an exhaust hole 2022 opened on the upper inside of the right fixed plate 2021, an exhaust pipe 2023 connected to the outside of the exhaust hole 2022, and the exhaust pipe 2023 extends upward to the outside of the box body 101, a clearance opening 2024 opened below the right fixed plate 2021, a T-shaped push plate 2025 laterally inserted into the clearance opening 2024, a fixed pipe 2026 laterally arranged outside the center position of the right fixed plate 2021, and an installation groove 2027 opened inside the fixed pipe 2026, and the switching unit 300 is installed in the installation groove 2027.

[0049] During use, the concave structures of the left fixed disk 2011 and the right fixed disk 2021 can surround and seal the two ends of the filter component 205, thereby preventing the exhaust gas from leaking during the filtration process. The two can then cooperate with the support plate 203 to install and fix the filter component 205. The exhaust hole 2022 and the exhaust port 2013 are on the same axis, and the exhaust pipe 2023 is used to discharge the gas filtered by the filter component 205. The T-shaped push plate 2025 is slidably inserted in the make way port 2024 and can be displaced horizontally in the make way port 2024.

[0050] Among them, combined Figure 5 The connecting component 204 includes a connecting pipe 2041 located in the discharge 2013, and an upper connecting pipe 2042 and a lower connecting pipe 2043 symmetrically arranged on the upper and lower sides of the connecting pipe 2041, and the upper connecting pipe 2042 and the lower connecting pipe 2043 are respectively connected to the switching component 105 and the small spiral heat release tube 104, and the inner ends of the upper connecting pipe 2042 and the lower connecting pipe 2043 are both connected to the connecting pipe 2041.

[0051] Among them, combined Figure 5 The filter component 205 includes a filter bin 2051 located between the left fixed disk 2011 and the right fixed disk 2021, and the two ends of the filter bin 2051 extend into the left fixed disk 2011 and the right fixed disk 2021 respectively, four groups of filter element compartments 2052 are equally divided and horizontally opened on the filter bin 2051, and each group of filter element compartments 2052 is provided with a filter element, and a hexagonal groove 2053 is horizontally opened at the axial position of the filter bin 2051, and one end of the hexagonal column 304 is matched and inserted in the hexagonal groove 2053.

[0052] During use, since the hexagonal prism 304 is inserted into the hexagonal groove 2053, the hexagonal groove 2053 can follow the hexagonal prism 304 to rotate in a circle with the hexagonal prism 304 as the axis, and among the four groups of filter element compartments 2052, there will always be two groups that are respectively located between the discharge port 2013 and the exhaust hole 2022, and between the filter hole 2012 and the clearance port 2024. The filter element in the filter element compartment 2052 located between the filter hole 2012 and the clearance port 2024 can be pushed out of the filter hole 2012 by the T-shaped push plate 2025 slidably connected to the clearance port 2024, thereby realizing the removal operation of the filter element.

[0053] Among them, combined Figure 8 The fixing component 301 includes four groups of equally divided and surrounding limiting arc plates 3011, and the four groups of limiting arc plates 3011 are transversely fixed in the installation groove 2027, a limiting slide groove 3012 is located between every two groups of limiting arc plates 3011, and a guide edge 3013 is opened at the top of the limiting arc plate 3011, and the guide edge 3013 is set at an inclined angle.

[0054] During use, the four groups of limiting grooves 3012 divide the circumference of the fixed component 301 equally, and the angle between each two groups of limiting grooves 3012 is 90 degrees. The two ends of the guide edge 3013 are inclined from one side of one group of limiting grooves 3012 to the other side of the other group of limiting grooves 3012. Therefore, an object sliding along the guide edge 3013 can slide from one group of limiting grooves 3012 into another group of limiting grooves 3012.

[0055] Among them, combined Figure 8 The pushing component 302 includes a pushing tube 3021 slidably connected between four groups of limiting arc plates 3011, a plurality of groups of latch teeth 3022 equally arranged around the outer end of the pushing tube 3021, and both sides of each group of latch teeth 3022 are inclined outward, four groups of limiting blocks 3023 equally arranged around the outer wall of the pushing tube 3021, and the limiting blocks 3023 extend outward into the limiting slide groove 3012, a pushing rod 3024 transversely fixedly connected to the other end of the pushing tube 3021, and a pressing plate 3025 fixedly connected to the outer end of the pushing rod 3024.

[0056] During use, the pushing component 302 is limited in the limiting groove 3012 by the limiting block 3023, so it can only slide horizontally along the limiting groove 3012. At the same time, an empty groove with a diameter larger than the size of the hexagonal prism 304 is opened inside the push rod 3024, so one end of the hexagonal prism 304 can extend into the push rod 3024, and the two will not limit each other.

[0057] Among them, combined Figure 8The adapter component 303 includes an adapter block 3031 located between four groups of limiting arc plates 3011, four groups of guide blocks 3032 equally divided and arranged around the outer wall of the adapter block 3031, and the top of the guide block 3032 is arranged at an inclined angle, and a hexagonal slot 3033 is transversely opened at the axial position of the adapter block 3031, and the hexagonal column 304 is transversely inserted into the hexagonal slot 3033, the guide block 3032 extends outward into the limiting slide groove 3012, and the top of the guide block 3032 abuts against the latch tooth 3022.

[0058] During use, the adapter component 303 is always in the form of a guide block 3032 abutting against the latch tooth 3022 under the elastic support of the return spring 305, and the hexagonal prism 304 passes through the hexagonal slot 3033, so there is a circumferential limit between the two. Therefore, the adapter component 303 can drive the hexagonal prism 304 to rotate synchronously in a circle through the hexagonal slot 3033, and the adapter component 303 is limited by the limiting slide groove 3012 through the side guide block 3032. Therefore, the adapter component 303 is limited by the limiting slide groove 3012 when it is not disengaged.

[0059] In summary, when the filter element in the filter component 205 needs to be replaced, there is no need to shut down the equipment. Pressing the pushing component 302 can push the adapter component 303 to slide in the fixing component 301. At this time, the reset spring 305 is compressed, while the hexagonal prism 304 remains stationary. At the same time, the top of the guide block 3032 abuts against the position of one-half of the side of the latch teeth 3022, and is not fully inserted into the gap between the latch teeth 3022 (such as Figure 8 When the pushing component 302 pushes the adapter component 303 to move to the end of the fixing component 301, the latch tooth 3022 is disengaged from the limiting position of the limiting slide groove 3012. Under the reverse force of the reset spring 305, the top of the latch tooth 3022 at the outer end of the adapter component 303 is completely stuck in the slot between the latch teeth 3022. At this time, the adapter component 303 is misaligned to a certain extent. At this time, the pushing component 302 is released, and the reset spring 305 rebounds strongly, pushing the adapter component 303 so that the top of the latch tooth 3022 moves along the guide edge 301. 3 slides (as shown in FIG9), and then enters another set of limiting slide grooves 3012. At this time, the adapter component 303 has rotated 90 degrees compared with the initial state. Due to the mutual limitation of the adapter component 303 and the hexagonal prism 304, the hexagonal prism 304 drives the filter component 205 to rotate 90 degrees, and then the filter element compartment 2052 located between the discharge port 2013 and the exhaust hole 2022, which is equipped with the filter element to be replaced, is switched to the filter element compartment 2052 equipped with a new filter element, thereby realizing the replacement of the filter element, and there is no need to stop the machine when switching the new filter element.
