[0002] The RTO organic waste gas treatment system will generate a large amount of high-temperature flue gas during the waste gas treatment process. In order to improve the energy utilization rate during the operation of the RTO organic waste gas treatment system, the flue gas generated is usually subjected to waste heat recovery.

[0003] At present, the flue gas generated during the operation of the RTO organic waste gas treatment system is usually used for hot water, which can provide hot water for workshop heating equipment (workshop hot water boiler circulation), residents' daily water use, etc. The waste heat recovery method in the above uses is generally to let the pipes that transport tap water pass through the flue gas, and the heat of the flue gas is transferred to the water inside through the pipe to heat it, so that the heated water can be sent to the occasions where hot water is needed.

[0004] However, the water temperature delivered to places where hot water is needed in the above manner has a large uncertainty, and the degree of uncertainty depends on the operation process of the RTO organic waste gas treatment system.

[0033] The partition 2 is a rectangular plate-shaped structure as a whole. The partition 2 is fixedly mounted on the box body 1 and is located in the cavity 11, and the thickness direction and width direction of the partition 2 are parallel to the length direction and width direction of the box body 1 respectively. The two ends of the partition 2 in the width direction are fixedly connected to the two side walls of the cavity 11 in the width direction, and the bottom of the partition 2 is fixedly connected to the cavity wall at the bottom of the cavity 11. The partition 2 separates the cavity 11 into a heat storage space 111 for storing heated tap water and a supplementary space 112 for storing tap water that has just been replenished, and the heat storage space 111 and the supplementary space 112 are respectively located on both sides of the thickness direction of the partition 2. An overflow port 113 is formed in the cavity 11 above the partition 2, so that the hot water in the heat storage space 111 can overflow into the supplementary space 112 through the overflow port 113. In this embodiment, it is preferred that the partition 2 is centered in the cavity 11, that is, the size of the heat storage space 111 is the same as the size of the supplementary space 112.

[0034] The box body 1 is provided with a replenishment port 12, an outflow port 13, a return port 14 and a water delivery port 15. The replenishment port 12 is used for tap water to be replenished and enter the box body 1; the outflow port 13 is used for tap water in the box body 1 to flow out through the flue gas generated during the operation of the RTO organic waste gas treatment system; the return port 14 is used for tap water after waste heat recovery to enter the box body 1; and the water delivery port 15 is used for hot water of the required temperature to be delivered to the water use location.

[0035] The replenishing port 12 and the outflow port 13 are both located on one side of the box body 1 in the length direction close to the replenishing space 112, the replenishing port 12 is communicated with the space in the cavity 11 located above the replenishing space 112, and the outflow port 13 is communicated with the position of the replenishing space 112 close to the bottom of the box body 1; the return port 14 and the water delivery port 15 are both located on one side of the box body 1 in the length direction close to the heat storage space 111, the return port 14 is communicated with the space in the cavity 11 located above the heat storage space 111, and the water delivery port 15 is communicated with the position of the heat storage space 111 close to the bottom of the box body 1.

[0036] One end of the water supply pump 6 is fixedly connected to the housing 1 through a pipeline and communicates with the replenishment port 12, and the other end of the water supply pump 6 leads to the tap water source; both ends of the circulation pump 7 are fixedly connected to the housing 1 through a pipeline, the pipeline passes through the flue gas generated during the operation of the RTO organic waste gas treatment system, and the two ends of the pipeline are respectively communicated with the outflow port 13 and the return port 14; one end of the water delivery pump 8 is fixedly connected to the housing 1 through a pipeline and communicates with the water delivery port 15, and the other end of the water delivery pump 8 leads to the water use. In this embodiment, since the water supply pump 6, the circulation pump 7 and the water delivery pump 8 are all common existing technologies, they are not described here in detail, and they and their supporting pipelines are only briefly represented in the attached drawings.

[0037] The thermometer 3 is fixedly installed through the box body 1 near the heat storage space 111, and part of the thermometer 3 is located in the heat storage space 111, so as to detect the water temperature in the heat storage space 111. In this embodiment, it is preferred that the thermometer 3 is fixedly installed through the box body 1 in a direction parallel to the width direction of the box body 1; and it is preferred that the part of the thermometer 3 located in the heat storage space 111 is centered in the heat storage space 111 along the vertical direction.

[0038] The thermometer 3 is connected to the water delivery pump 8 by signal, and the staff can preset the detection value of the thermometer 3 according to the water demand. When the thermometer 3 detects that the water temperature in the heat storage space 111 is lower than the preset value, the thermometer 3 will control the water delivery pump 8 to remain in a closed state; when the thermometer 3 detects that the water temperature in the heat storage space 111 is equal to or higher than the preset value, the thermometer 3 will control the water delivery pump 8 to operate and deliver hot water of the required temperature to the water use location. In this embodiment, since the thermometer 3 with the above-mentioned function is a common prior art, it will not be described in detail here, and it is only briefly represented in the accompanying drawings.

[0039] The liquid level meter 4 is fixedly installed on one side of the box body 1 close to the heat storage space 111 in the length direction, and can display the water level in the heat storage space 111 to the outside, so that the staff can understand the amount of water stored in the heat storage space 111, the speed of hot water use, and other information outside the box body 1, thereby facilitating the staff to adjust the replenishment speed of tap water in the replenishment space 112 and the rate of tap water waste heat recovery. In this embodiment, since the liquid level meter 4 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0040] The detector 5 is fixedly mounted on the box body 1, located at the top of the replenishing space 112 near the replenishing port 12, and can detect the water level in the replenishing space 112. In this embodiment, the water level detection height of the detector 5 is preferably aligned with the top of the partition 2 in the horizontal direction.

[0041] The detector 5 is connected to the replenishing pump signal. When the detector 5 detects that the water level of the tap water in the replenishing space 112 is lower than its water level detection height, the detector 5 will control the replenishing pump to replenish the tap water in the replenishing space 112 until the water level of the tap water in the replenishing space 112 is flush with the water level detection height of the detector 5. In this embodiment, since the detector 5 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0042] Since tap water contains more particulate matter and is prone to scale formation after heating, the particulate matter will be mainly concentrated at the bottom of the replenishment space 112 , and scale will be mainly formed at the bottom of the heat storage space 111 .

[0043] In order to facilitate the staff to enter the cavity 11 to clean the particles and scale, and to facilitate the staff to repair the structure inside the cavity 11, it is preferred that two inspection ports 16 are provided on the top of the box body 1 for the staff to enter and exit the cavity 11. The two inspection ports 16 correspond to the heat storage space 111 and the supplementary space 112 one by one, and the two inspection ports 16 are aligned with the heat storage space 111 and the supplementary space 112 in the vertical direction.

[0044] In order to facilitate the control of the opening and closing of the inspection port 16, a cover plate adapted to the inspection port 16 is preferably movably installed on the top of the box body 1. In this embodiment, the cover plate is preferably rotatably connected to the box body 1, and the rotation axis of the cover plate is preferably parallel to the length direction of the box body 1; since the cover plate with the above function is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0045] Furthermore, in order to facilitate the staff to clean and discharge the particles and scale in the cavity 11, it is preferred that a plurality of drain ports 17 with controllable opening and closing are provided on the housing 1. The plurality of drain ports 17 are respectively connected to the bottom of the heat storage space 111 and the bottom of the supplementary space 112, so that the staff can discharge the scale in the heat storage space 111 and the particles in the supplementary space 112 to the outside of the housing 1 through the corresponding drain ports 17. In this embodiment, since the drain ports 17 with the above functions are common prior art, they are not described in detail here, and the controllable opening and closing structure of the drain ports 17 is omitted in the attached drawings.

[0046] The implementation principle of the flue gas waste heat recovery device of the RTO organic waste gas treatment system in the embodiment of the present application is: During the waste heat recovery process, the circulation pump 7 keeps running, so that the tap water in the supplementary space 112 is transported through the pipeline to the flue gas generated during the operation of the RTO organic waste gas treatment system for waste heat recovery, and the heated tap water enters the heat storage space 111 for storage; When the thermometer 3 detects that the tap water temperature in the heat storage space 111 is lower than a preset value, the excess water in the heat storage space 111 will enter the supplementary space 112 through the overflow port 113 to circulate until the tap water temperature in the heat storage space 111 is equal to or higher than the preset value, and the thermometer 3 will control the water delivery pump 8 to drive the water in the heat storage space 111 to the water use location; When the amount of water in the cavity 11 decreases due to water delivery, the detector 5 will detect that the water level in the supplementary space 112 has dropped, thereby controlling the supplementary pump to replenish tap water into the supplementary space 112 in a timely manner until the water level in the supplementary space 112 is flush with the detected water level of the detector 5, so that the tap water can maintain a high waste heat recovery efficiency; After a period of waste heat recovery, the staff enters the supplementary space 112 and the heat storage space 111 through the inspection port 16 to clean the particulate matter and scale respectively, and discharge them through the sewage outlet 17 to improve the water supply quality.

[0047] Embodiment 2: Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 lies in the partition 2, the box body 1 and the thermometer 3.

[0048] Reference Figure 4 and Figure 5 The partition 2 is an arc-shaped plate structure as a whole. After it is installed on the box body 1, its arc trajectory is perpendicular to the height direction of the box body 1; the partition 2 can conduct heat, so that the heat of the tap water in the heat storage space 111 can be conducted to the tap water in the supplementary space 112 through the partition 2, and the partition 2 has the characteristics of thermal expansion and contraction, which is convenient for it to deform according to the temperature change of the surrounding tap water, thereby extending its service life. In this embodiment, the partition 2 is preferably made of a metal material with strong thermal conductivity and thermal expansion and contraction properties; since the above-mentioned metal material is a common prior art, its specific type is not further limited here.

[0049] Reference Figure 4 and Figure 6 , one end of the arc track of the partition 2 is rotatably connected to the box body 1, and its rotation axis is parallel to the height direction of the box body 1 and perpendicular to its own arc track; multiple seals 21 are fixedly installed at the edge of the partition 2, and the multiple seals 21 are respectively located on both sides of the arc track of the partition 2 and the bottom of the partition 2. During the rotation of the partition 2 relative to the box body 1, the partition 2 can contact and abut against the cavity walls on both sides and the bottom of the cavity 11 in the width direction through the seals 21. In this embodiment, the seal 21 is preferably elastic to reduce the probability of damage to the partition 2 itself and the box body 1 during the process of thermal expansion and contraction affected by temperature; and the seal 21 is preferably made of rubber material.

[0050] Reference Figure 5 and Figure 7, the partition 2 is limited in its rotation relative to the box body 1.

At this time, the partition 2 can effectively separate the supplementary space 112 and the heat storage space 111 in the cavity 11, and the arc of the partition 2 is facing the heat storage space 111; when the partition 2 is close to the heat storage space 11 1 is rotated to the extreme position, the end of the partition 2 close to its own rotation axis is kept in contact with the cavity wall on one side of the width direction of the cavity 11 through the corresponding seal 21, and the end of the partition 2 away from its own rotation axis is kept in contact with the corner of the cavity 11 through the corresponding seal 21, and the bottom of the partition 2 will also be in contact with the cavity wall at the bottom of the cavity 11 through the corresponding seal 21, and the seal 21 still achieves sealing between the partition 2 and the corresponding cavity wall of the cavity 11. At this time, a gathering space 114 for gathering cleaned scale is formed between the concave surface of the partition 2 and the adjacent cavity wall of the cavity 11.

[0051] Reference Figure 6 and Figure 8 During the rotation of the partition 2 relative to the box body 1, the bottom of the partition 2 can clean the scale located in the fan-shaped range at the bottom of the heat storage space 111 through the corresponding seal 21, and can push the cleaned scale in the range to move into the gathering space 114.

[0052] Reference Figure 3 and Figure 6 A driving member 10 is also fixedly mounted on the bottom of the box body 1, and the driving member 10 can drive the partition 2 to rotate relative to the box body 1. In this embodiment, the driving member 10 is preferably a servo motor; since the servo motor is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0053] Reference Figure 7 and Figure 8, the positions of the drain outlets 17 on the box body 1 are all close to the heat storage space 111. When the partition 2 rotates to the extreme position in the direction close to the heat storage space 111, part of the drain outlets 17 are connected to the gathering space 114, and the remaining drain outlets 17 will be connected to the space on the side of the partition 2 away from the gathering space 114 in the cavity 11; at this time, the scale cleaned by the partition 2 and gathered in the gathering space 114 will be able to be directly discharged through the corresponding drain outlets 17, and a larger operating space is provided in the cavity 11 for the staff to clean the supplementary space 112, and it is convenient for the staff to gather the particles in the supplementary space 112 to the side of the partition 2 away from the gathering space 114, and then discharge them together with the scale in the dead corner cleaned by the partition 2 through the corresponding drain outlets 17. In this embodiment, it is preferred that there are two drain outlets 17 on the box body 1, and the two drain outlets 17 are respectively located on both sides of the width direction of the box body 1.

The thermometer 3 is located in the rotation area of ​​the partition 2 in the heat storage space 111, and the temperature detection position of the thermometer 3 in the heat storage space 111 is also centered in the heat storage space 111 in the vertical direction.

[0055] Reference Figure 4 and Figure 5 The box body 1 is also fixedly installed with a filtering device 9 for filtering tap water in the supplementary space 112 . The filtering device 9 is located at the top of the supplementary space 112 and is lower than the top of the partition 2 .

[0056] Reference Figure 4 The filter device 9 includes a filter plate 91 and a filter medium 92, wherein the filter medium 92 is used to adsorb particles in the tap water. In this embodiment, the filter medium 92 is preferably activated carbon particles.

[0057] Reference Figure 5 and Figure 6 The filter plate 91 is a rectangular plate-shaped structure as a whole, and is fixedly installed on the box body 1 in a horizontal position; the three sides of the filter plate 91 are respectively fixedly connected to the two side walls of the cavity 11 in the width direction and the side wall close to the supplementary space 112 in the length direction, and the side of the filter plate 91 close to the heat storage space 111 has a concave arc structure adapted to the partition 2; when the partition 2 rotates to the extreme position in the direction close to the supplementary space 112, the partition 2 is in contact with the filter plate 91 and the surfaces are in contact with each other.

[0058] Reference Figure 4 and Figure 6The filter plate 91 has a cavity 911 inside for accommodating the filter medium 92. The shape of the cavity 911 is a fan-shaped plate structure with the rotation axis of the partition 2 as the axis, and the cavity 911 penetrates the side of the filter plate 91 close to the heat storage space 111 to form an outlet 912 for the filter medium 92 to leave the cavity 911; when the partition 2 rotates to the extreme position in the direction close to the supplementary space 112, the partition 2 can block the outlet 912 to prevent the filter medium 92 from leaving the outlet 912.

[0059] Reference Figure 5 and Figure 6 A feed port 913 for the filter medium 92 to enter the cavity 911 is provided on the filter plate 91 at a position away from the rotation axis of the partition plate 2. One end of the feed port 913 is in communication with the cavity 911, and the other end passes through the top of the filter plate 91 to form an opening. In this embodiment, the size of the feed port 913 is preferably larger than the maximum particle size of the filter medium 92; and the filter plate 91 is preferably equipped with a detachable block for controlling the opening and closing of the feed port 913 at the feed port 913; since the block with the above function is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0060] Reference Figure 5 and Figure 6 The top and bottom of the filter plate 91 are provided with a plurality of through holes 914 for the flow of tap water. The plurality of through holes 914 are evenly distributed on the filter plate 91 and are all connected to the cavity 911. In this embodiment, the size of the through holes 914 is preferably smaller than the minimum particle size of the filter medium 92.

[0061] At this time, the tap water in the supplementary space 112 will pass through the filter device 9 before being transported through the outflow outlet 13 for waste heat recovery. After being adsorbed and filtered by the filter medium 92, the particulate matter content in the tap water is reduced, thereby reducing the concentration of particulate matter at the bottom of the supplementary space 112, further improving the subsequent tap water supply quality.

[0062] Reference Figure 6 and Figure 7A cleaning piece 22 for cleaning the filter medium 92 is fixedly installed on the partition 2. The cleaning piece 22 is a rod-shaped structure as a whole. One end of the cleaning piece 22 in the length direction is fixedly connected to the position of the partition 2 close to its own rotation axis, and the length direction of the cleaning piece 22 is perpendicular to the rotation axis of the partition 2; the other end of the cleaning piece 22 in the length direction is located in the cavity 911. During the rotation of the cleaning piece 22 with the rotation of the partition 2, the cleaning piece 22 can maintain contact with the inner wall of the cavity 911 and sweep the entire cavity 911; when the partition 2 rotates to the extreme position in the direction close to the supplementary space 112, the cleaning piece 22 is located at one end of the cavity 911 close to the cavity wall of the cavity 11 side (preferably, a corresponding make-away groove adapted to the cleaning piece 22 is provided on the cavity wall of the cavity 11); when the partition 2 rotates to the extreme position in the direction close to the heat storage space 111, the cleaning piece 22 is located at the position of the cavity 911 close to the discharge port 912; in the process of the partition 2 rotating from the position state of blocking the discharge port 912 in the direction close to the heat storage space 111 to the extreme position, the cleaning piece 22 can clear the filter medium 92 in the cavity 911 from the discharge port 912, and at this time, the filter medium 92 will fall into the space on the side of the partition 2 away from the gathering space 114 in the cavity 11, so that the filter medium 92 is discharged through the corresponding sewage outlet 17 together with other garbage.

[0063] Reference Figure 5 and Figure 7 , two clearing members 23 for cleaning the surface of the filter plate 91 are fixedly mounted on the partition 2. The clearing member 23 is also a rod-shaped structure as a whole. One end of the clearing member 23 in the length direction is also fixedly connected to the position of the partition 2 close to its own rotation axis, and the length direction of the clearing member 23 is parallel to the length direction of the clearing member 22; the two clearing members 23 are respectively located at the top and bottom of the filter plate 91, and are respectively in contact with the surface of the top and the surface of the bottom of the filter plate 91. In this embodiment, it is preferred that the clearing member 23 has a soft bristle structure on the side close to the filter plate 91, which can enter the through hole 914 to clean the through hole 914; since the bristle structure with the above-mentioned function is a common prior art, it will not be described here in detail, and it is omitted in the drawings.

[0064] As the two clearing members 23 rotate along with the partition 2, the two clearing members 23 can clean the top and bottom surfaces of the filter plate 91, thereby reducing the probability of particulate matter or filter medium 92 clogging the through hole 914, making it more convenient and quick for staff to clean the filter device 9.

[0065] The implementation principle of the flue gas waste heat recovery device of the RTO organic waste gas treatment system in the embodiment of the present application is: Before the tap water in the supplementary space 112 is transported through the flue gas generated during the operation of the RTO organic waste gas treatment system for waste heat recovery, it first passes through the filter device 9, enters the cavity 911 through multiple through holes 914, and then contacts the filter medium 92, so that some particles in the tap water can be adsorbed by the filter medium 92. The tap water after some particles are adsorbed by the filter medium 92 flows out through multiple through holes 914, waiting to be transported for waste heat recovery; After the waste heat is recovered for a period of time, the control driving member 10 drives the partition 2 to rotate to the extreme position in the direction close to the heat storage space 111. At this time, the partition 2 will clean the scale in a certain area at the bottom of the heat storage space 111 and concentrate it in the gathering space 114; at the same time, the partition 2 will drive the cleaning member 22 to clean out the filter medium 92 in the cavity 911, so that the staff can replace the filter medium 92; and the partition 2 will drive the two clearing members 23 to clean the upper and lower surfaces of the filter plate 91, reducing the probability of the through hole 914 being blocked by impurities such as particles; At this time, it is convenient for the staff to first enter the supplementary space 112 to clean the particulate matter in the supplementary space 112, the filter medium 92 that falls to the side of the partition 2 away from the gathering space 114, and the scale in the heat storage space 111 on the side of the partition 2 away from the gathering space 114, and then discharge them through the corresponding sewage outlet 17; then control the driving member 10 to drive the partition 2 to rotate and reset, and the staff enters the heat storage space 111 again to clean the scale previously concentrated in the gathering space 114 and discharge it through the corresponding sewage outlet 17.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
