Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a rotary RTO device for treating chemical waste gas. Background Art

[0002] A Chinese invention patent with publication number CN109855106A discloses a rotary RTO waste gas treatment device for waste heat recovery. The telescopic end of the pneumatic cylinder drives the piston to move back and forth in the waste gas compression tank. During the continuous back and forth movement, the waste gas enters the waste gas compression tank through the second waste gas inlet pipe and the third one-way valve and the fourth one-way valve. The third one-way valve and the fourth one-way valve ensure that the waste gas enters the waste gas compression tank in one direction. At the same time, when the piston moves back and forth, the waste gas enters the waste gas compression tank and continuously passes through the first one-way valve, the second one-way valve and the first waste gas inlet pipe into the insulation tank body. The first one-way valve and the second one-way valve ensure that the waste gas enters the insulation tank body in one direction. The two pipe openings on the same side of the first waste gas inlet pipe and the second waste gas inlet pipe are respectively located at both ends of the waste gas compression tank to ensure continuous and uniform waste gas transportation.

[0003] In the related art, when the existing rotary RTO equipment carries out combustion treatment on the waste gas, it generally directly discharges the chemical waste gas into the furnace body through a rotary valve for combustion, and the combusted gas is then discharged into the chimney through a circulation valve for extraction. However, when the waste gas is burned in the furnace body, the waste gas purification effect is affected due to insufficient preheating of the waste gas in the early stage and incomplete subsequent combustion. In addition, when the waste gas is preheated, the post-combustion gas is not fully utilized, which not only causes environmental pollution, but also increases the working energy consumption of the equipment and reduces the energy-saving and environmental protection performance of the equipment. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a rotary RTO device for treating chemical waste gas. Through the setting of a circulation component, the device is used to discharge the gas treated by combustion and purification into a heat exchange component. The heat exchange component can be used to preheat the chemical waste gas entering the RTO furnace body, which can not only fully utilize the heat of the purified gas and reduce the working energy consumption of the RTO furnace body, but also avoid the extraction of high-temperature gas to cause environmental pollution. Through the setting of the circulation component, the waste gas that is not completely burned and purified can be circulated and discharged into the RTO furnace body to form a cyclic combustion purification treatment, which solves the problem that the rotary RTO device in the prior art reduces the waste gas treatment effect due to incomplete combustion when purifying the waste gas, and cannot fully utilize the heat of the waste gas after combustion and purification.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See attached Figure 1-11 A rotary RTO device for treating chemical waste gas comprises a bottom plate 1, an RTO furnace body 2 is fixedly connected to the top of the bottom plate 1, a rotary valve body 3 is fixedly installed at the bottom of the RTO furnace body 2, the top of the rotary valve body 3 extends to the inside of the RTO furnace body 2, a heat storage ceramic body 4 is installed on the top of the rotary valve body 3, a burner 5 is installed on one side of the RTO furnace body 2, and a natural gas pipe is arranged on the burner 5, a heat exchange component 6 and a chimney 7 are respectively installed on both sides of the top of the bottom plate 1, and the heat exchange component 6 is connected to the heat exchange component 6 through a pipeline. The rotary valve body 3 and the chimney 7 are connected, and the gas outlet end of the rotary valve body 3 is connected to the inside of the chimney 7 through the gas outlet pipe 8. A circulation component 9 for discharging the high-temperature gas inside the RTO furnace body 2 to the inside of the heat exchange component 6 and for circulating the insufficiently heated gas inside the gas outlet pipe 8 to the inside of the RTO furnace body 2 is fixedly installed on the top of the bottom plate 1. The circulation component 9 is installed on the top of the bottom plate 1 and is located on the back of the RTO furnace body 2. A pressure regulating component 10 is arranged on the front of the RTO furnace body 2.

[0038] By discharging the chemical waste gas into the interior of the RTO furnace body 2, the chemical waste gas inside the RTO furnace body 2 is burned and purified by the burner 5, and the treated gas is discharged through the chimney 7;

[0039] The circulation component 9 is used to discharge the combustion and purification gas into the heat exchange component 6. The heat exchange component 6 can preheat the chemical waste gas entering the RTO furnace body 2, which can not only fully utilize the heat of the purified gas, reducing the working energy consumption of the RTO furnace body 2, but also avoid the extraction of high-temperature gas to cause environmental pollution;

[0040] By setting the circulation component 9, the waste gas that is not completely burned and purified can be circulated and discharged into the RTO furnace body 2, forming a cyclic combustion purification treatment, further improving the treatment effect of its chemical waste gas.

[0041] See attached Figure 3 , Figure 5 , Figure 6 and Figure 7The circulation assembly 9 includes a circulation drum 91 fixed to the top of the bottom plate 1, a compression member 92 is arranged inside the circulation drum 91, a Y-shaped tube 93 is fixedly connected to the gas outlet pipe 8, and both ends of the Y-shaped tube 93 are respectively connected to the top and the bottom of the circulation drum 91, a first non-return valve is installed on the Y-shaped tube 93, and both ends of the Y-shaped tube 93 are installed with a switch valve, a circulation tube 94 is fixedly connected between the top of the circulation drum 91 and the inside of the RTO furnace body 2, and the bottom of the circulation drum 91 is connected to the heat exchange assembly 6 through a preheating tube 95, and a second non-return valve is installed on the circulation tube 94 and the preheating tube 95;

[0042] By setting the Y-tube 93, the gas originally discharged from the outlet pipe 8 to the chimney 7 can be discharged to the interior of the circulation tube 91. The Y-tube 93 has two outlets, which makes it convenient for the staff to control the two switch valves to make the gas inside the Y-tube 93 be discharged to the upper cavity or the lower cavity of the circulation tube 91, thereby realizing the circulating combustion treatment of the gas or the utilization of the gas heat. The second one-way valve installed on the circulation tube 94 and the preheating tube 95 can be used to control the circulation tube 94 and the preheating tube 95 in one-way manner, so as to prevent the gas inside the RTO furnace body 2 from entering the circulation tube 91 through the circulation tube 94, and to prevent the gas in the heat exchange component 6 from entering the circulation tube 91 through the preheating tube 95, thereby having the function of one-way gas control.

[0043] See attached Figure 6 and Figure 7 The compression member 92 includes a piston plate 921 slidably connected to the inside of the circulation cylinder 91, and a driving rod 922 is fixedly connected to the top of the piston plate 921, and the top of the driving rod 922 extends to the top of the circulation cylinder 91. A telescopic cylinder 923 for driving the driving rod 922 up and down is fixedly connected to the outer surface of the circulation cylinder 91. The telescopic end of the telescopic cylinder 923 is fixedly connected to the top of the driving rod 922 through a bracket. Through holes are opened on the outer surfaces of the top and bottom of the circulation cylinder 91, and caps 924 are detachably installed at the two through holes.

[0044] The telescopic cylinder 923 is connected to an external power supply and a control switch, and is used to drive the driving rod 922 to move up and down. The up and down movement of the driving rod 922 can drive the piston plate 921 to move up and down. The up and down movement of the piston plate 921 can control the air pressure at the top and bottom of the circulation cylinder 91, and then the Y-shaped tube 93 can discharge the gas treated at high temperature into the circulation cylinder 91, and circulate it into the interior of the RTO furnace body 2 through the circulation tube 94 for circulation treatment, thereby further improving its waste gas treatment effect. Moreover, through the setting of the preheating tube 95, the treated gas can be discharged into the heat exchange component 6, and the chemical waste gas to be treated can be preheated, thereby improving the treatment effect of the RTO furnace body 2 on the chemical waste gas and reducing the working energy consumption of the RTO furnace body 2;

[0045] The arrangement of the two caps 924 facilitates the control of the two openings, and the arrangement of the two openings facilitates ventilation between the top space or the bottom space of the circulation cylinder 91 and the outside, thereby facilitating the up and down movement of the piston plate 921. The heated gas can be discharged separately to the interior of the RTO furnace body 2 or the heat exchange component 6, thereby improving the diversity of the circulation component 9. Not only can the waste gas that has not been completely treated at high temperature be subjected to circulating combustion treatment, but the heat of the waste gas after high-temperature treatment can also be utilized, and the two can be operated synchronously, further improving the functionality of the circulation component 9.

[0046] See attached Figure 5 , Figure 8 , Fig. 9 and Fig.10 The heat exchange assembly 6 includes a heat exchange cylinder 61 fixed to the top of the bottom plate 1, and one side of the heat exchange cylinder 61 is connected to the air inlet end of the rotary valve body 3 through an air delivery pipe 62. Two partition plates 63 are fixedly connected to the inside of the heat exchange cylinder 61. A plurality of capillary heat exchange tubes 64 are fixedly connected between the insides of the two partition plates 63. A circular collecting frame 65 is fixedly connected to the left partition plate 63, and the inside of the collecting frame 65 is connected to the inner side surfaces of the two partition plates 63 through an air guide frame. One end of the preheating pipe 95 is connected to the inner side of the two partition plates 63. The interior of the collecting frame 65 is connected, the interior of the heat exchange tube 61 is fixedly connected with an exhaust pipe 66, one end of the exhaust pipe 66 is located between the two partition plates 63, and the other end of the exhaust pipe 66 is connected with the interior of the chimney 7, a third one-way valve is installed on the exhaust pipe 66, two groups of cross-shaped guide plates are fixedly connected between the two partition plates 63, a filter element 67 for filtering exhaust gas is provided on the other side of the heat exchange tube 61, and a driving element 68 for cleaning the filter element 67 is provided inside the collecting frame 65;

[0047] The high-temperature gas inside the RTO furnace body 2 is discharged to the collecting frame 65 through the setting of the preheating pipe 95, and the high-temperature gas is discharged to between the two partition plates 63 through the air guide frame on the collecting frame 65, so as to form the preheating work of the chemical waste gas, and the heat exchanged gas is discharged to the chimney 7 through the exhaust pipe 66 for discharge work, so as to fully utilize the heat of the waste gas after high-temperature treatment;

[0048] By discharging the exhaust gas into the interior of the heat exchange tube 61, the exhaust gas inside the heat exchange tube 61 is discharged to the other side of the heat exchange tube 61 through a plurality of capillary heat exchange tubes 64. During the flow diversion process, the exhaust gas can fully exchange heat with the hot air between the two partition plates 63, thereby forming a preheating work of the exhaust gas. The two groups of cross-arranged guide plates can increase the flow route of the high-temperature exhaust gas inside the heat exchange tube 61, and fully utilize the heat of the treated exhaust gas. This not only improves the subsequent RTO furnace body 2's exhaust gas treatment effect, but also avoids the high-temperature gas from being discharged into the environment, causing environmental damage, and has good energy-saving and environmental protection functions.

[0049] See attached Fig. 9 The filter element 67 includes a collecting cover 671 detachably mounted on the other side of the heat exchange tube 61, and one end of the collecting cover 671 is connected to the external negative pressure fan, and the inner surface of the other end of the heat exchange tube 61 is fixedly connected with a filter plate 672;

[0050] By connecting the collecting hood 671 to the external negative pressure fan, the chemical waste gas to be treated can be discharged to the inside of the heat exchange tube 61 through the negative pressure fan. By setting the filter plate 672, the particulate matter in the chemical waste gas can be preliminarily treated, which not only improves the effect of subsequent high-temperature treatment of the chemical waste gas, but also reduces the contact amount between the particulate matter and the heat storage ceramic body 4 during the high-temperature treatment, which facilitates the subsequent cleaning of the heat storage ceramic body 4.

[0051] Embodiment 2: Based on embodiment 1, the difference is that;

[0052] See attached Fig. 9 and Fig.10 The driving member 68 includes a transmission shaft 681 rotatably connected to one side of the inner wall of the collecting frame 65, a plurality of toggle plates 682 are fixedly connected to the transmission shaft 681, a connection frame 683 is fixedly connected to the outer side of the collecting frame 65, and an inclined air filling port 684 is opened between the connection frame 683 and the collecting frame 65, one end of the preheating pipe 95 is connected to the inside of the connection frame 683, one end of the transmission shaft 681 extends to the outer side of the filter plate 672, one end of the transmission shaft 681 is detachably mounted with a mounting frame 685, a brush and a scraper are respectively mounted on the top and bottom of one side of the mounting frame 685, and the brush and the scraper are in contact with the outer side of the filter plate 672;

[0053] By setting the preheating tube 95, the high-temperature treated gas can be discharged into the interior of the connecting frame 683, and the gas inside the connecting frame 683 can be discharged into the collecting frame 65 through the inclined gas filling port 684, and the impact force of the airflow can drive the plurality of toggle plates 682 to rotate, and further drive the transmission shaft 681 to rotate;

[0054] The rotation of the transmission shaft 681 can drive the mounting frame 685 to rotate, and finally the filter residue on the outer side of the filter plate 672 can be cleaned by the brush and scraper on the inner side of the mounting frame 685, thereby improving the stability of the subsequent continuous filtering work. It has a self-cleaning function, fully utilizes the airflow driving force, and improves the functionality of the heat exchange component 6.

[0055] Embodiment 3: Based on embodiment 1, the difference is that;

[0056] See attached Fig.11The pressure regulating assembly 10 includes an L-shaped frame 101 fixed to the front of the RTO furnace body 2, and the L-shaped frame 101 is connected to the inside of the RTO furnace body 2, a pressing plate 102 is slidably connected to the inside of the L-shaped frame 101, and an extrusion spring 103 for pressing the pressing plate 102 downward is arranged inside the L-shaped frame 101, and a venting port is opened at the top of one side of the L-shaped frame 101;

[0057] By using the elastic force of the extrusion spring 103 itself, the pressing plate 102 can be squeezed downward, so that the pressing plate 102 moves downward. When the internal pressure of the RTO furnace body 2 increases, its pressure can squeeze the pressing plate 102 upward, so that the pressing plate 102 moves upward. When the pressing plate 102 moves to the position of the air vent, the pressure inside the RTO furnace body 2 can be released through the air vent, thereby avoiding the problem of chamber explosion due to the high internal pressure of the RTO furnace body 2 during the exhaust gas treatment process, thereby improving the safety of its exhaust gas treatment.

[0058] The top of the inner wall of the L-shaped frame 101 is slidably connected with an adjustment plate 104, and the extrusion spring 103 is fixed between the adjustment plate 104 and the pressing plate 102, and a pressure sensor is arranged in the adjustment plate 104, and the top of the L-shaped frame 101 is threadedly connected with a screw rod 105, and the bottom end of the screw rod 105 is rotatably connected to the top of the adjustment plate 104;

[0059] By manually rotating the screw rod 105, the adjustment plate 104 can be driven to move up and down. The up and down movement of the adjustment plate 104 can adjust the elastic extrusion strength of the extrusion spring 103, thereby forming an adjustment of the extrusion force of the pressing plate 102 to meet the pressure relief work under different pressure conditions, and further improve the stability of the rotating RTO equipment during operation.
