Description

Technical Field

[0001] The present application relates to the field of waste gas treatment, and in particular to an organic waste gas treatment system. Background Art

[0002] Ink printing and other industries will produce a large amount of VOC (Volatile Organic Compounds) gas during their production activities. Most organic waste gases are harmful to the human body and the environment, so organic waste gases need to be treated for environmental protection before being discharged.

[0003] In the related technology, the existing organic waste gas systems treat organic waste gas by mixing the organic waste gas with fuel gas and then igniting it. After combustion, the organic waste gas can be converted into harmless high-temperature exhaust gases such as CO2 and H2O. The high-temperature exhaust gas can be discharged into the outdoor environment by the organic waste gas system. Since the high-temperature exhaust gas is directly discharged from the organic waste gas system, the waste heat in the high-temperature exhaust gas is not reused, thereby increasing the production energy consumption of the processing plant and affecting the operating costs of the processing plant. Summary of the invention

[0006] By adopting the above technical solution, by circulating the first heat exchange medium between the first heat exchange pipeline and the first heating pipeline, the heat of the high-temperature exhaust gas can be transferred to the heating device, so that the heating device can heat the organic material to produce organic waste gas. Compared with the prior art, the external energy required for the heating device to heat the organic material can be reduced, the waste heat utilization rate of the high-temperature exhaust gas can be improved, and the production energy consumption of the processing plant can be reduced.

[0014] By adopting the above technical solution, when the organic waste gas treatment system is initially started and the temperature of the first heat exchange medium flowing into the first heating pipeline is lower than the preset heating temperature range, the controller controls the opening of the gas control valve to increase, the gas flow rate flowing into the combustion chamber increases, the combustion of the combustible gas in the combustion chamber generates more heat, and more heat is transferred to the first heat exchange medium through the first heat exchanger, which helps to speed up the temperature rise of the first heat exchange medium, and further enable the temperature of the first heat exchange medium flowing into the first heating pipeline to reach the preset heating temperature range faster.

[0015] When the temperature of the first heat exchange medium flowing to the first heating pipeline exceeds the preset heating temperature range, the controller controls the opening of the gas control valve to decrease, the gas flow rate flowing into the combustion chamber is reduced, the heat generated by the combustion of the combustible gas in the combustion chamber is less, and the heat transferred to the first heat exchange medium through the first heat exchanger is less, thereby reducing the temperature of the first heat exchange medium flowing to the first heating pipeline to the preset heating temperature range.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0032] The embodiment of the present application discloses an organic waste gas treatment system 100, which is used to treat VOC gas (i.e., organic waste gas). The organic waste gas treatment system 100 can convert the organic waste gas generated by the processing plant into harmless gas for discharge. In some specific embodiments of the present application, the organic waste gas treatment system 100 is used to treat the organic waste gas generated by ink printing processing. When the ink is heated, the volatile organic compounds in the ink volatilize and generate organic waste gas. The technical solution of the present application is described below using the organic waste gas treatment system 100 for treating the organic waste gas generated by ink printing processing.

[0033] Reference Figure 1 and Figure 2 According to the organic waste gas treatment system 100 described in the embodiment of the present application, the organic waste gas treatment system 100 includes: a heating device 10, a combustion chamber 20, a vacuum part 30, an exhaust pipe 50 and a first heat exchanger 60. A first heating pipeline 101 is provided in the heating device 10 and is used to heat the organic material. When the heating device 10 heats the organic material, the organic material generates organic waste gas. When the organic waste gas treatment system 100 is used to treat the organic waste gas generated by ink printing, the heating device 10 can be an oven, and the organic material can be ink. When the oven dries the ink, the volatile substances in the ink are volatilized by heat to form organic waste gas. The organic waste gas gathers in the heating device 10 and the concentration increases. The heating device 10 can discharge the high-concentration organic waste gas to the outside of the heating device 10.

[0034] In addition, the combustion chamber 20 is provided with an air inlet 201 and an exhaust port 202. The air inlet 201 of the combustion chamber 20 is connected to the heating device 10, and the organic waste gas collected in the heating device 10 can be discharged into the combustion chamber 20 through the air inlet 201 of the combustion chamber 20. The vacuum member 30 is arranged between the combustion chamber 20 and the heating device 10 and is used to suck the organic waste gas in the heating device 10 into the combustion chamber 20. In some specific embodiments, the vacuum member 30 can be an air pump. The vacuum member 30 can form a negative pressure in the heating device 10, so that the organic waste gas can be collected and flow into the combustion chamber 20.

[0035] The combustion chamber 20 is suitable for being connected to the gas pipeline 40 to obtain gas, wherein the gas can be natural gas or water gas, etc. The combustion chamber 20 is used to ignite a mixture of the gas and the organic waste gas to generate a high-temperature exhaust gas. By mixing the organic waste gas with the gas, when the concentration of the organic waste gas is too low and the organic waste gas is difficult to ignite, the gas can increase the concentration of the combustible material in the combustion chamber 20, thereby allowing the organic waste gas to burn smoothly to form harmless exhaust gas. The exhaust port 202 is suitable for discharging the high-temperature exhaust gas.

[0036] At the same time, the exhaust pipe 50 is connected to the exhaust port 202, and the first heat exchanger 60 is arranged in the exhaust pipe 50. The first heat exchanger 60 has a first heat exchange pipeline 601 in it. The first heat exchange medium circulates between the first heat exchange pipeline 601 and the first heating pipeline 101, and the first heat exchange pipeline 601 is used to exchange heat with the exhaust pipe 50. When the first heat exchange medium exchanges heat with the exhaust pipe 50 in the first heat exchange pipeline 601, the temperature of the high-temperature exhaust gas is greater than the temperature of the first heat exchange medium, and the heat can be transferred from the high-temperature exhaust gas to the first heat exchange medium, and the temperature of the first heat exchange medium increases and the temperature of the high-temperature exhaust gas decreases. After the first heat exchange medium flows from the first heat exchange pipeline 601 to the first heating pipeline 101, the temperature in the heating device 10 is lower than the temperature of the first heat exchange medium. The heat of the first heat exchange medium can be transferred to the heating device 10 to heat the ink in the heating device 10. That is, the heat in the high-temperature exhaust gas can heat the ink through the first heat exchange medium. The organic waste gas generated in the ink can be used again to generate high-temperature waste gas after combustion, thereby achieving the technical effect of the organic waste gas treatment system 100 for recycling and processing ink.

[0037] It should be noted that when the organic waste gas treatment system 100 is used to treat the ink produced by ink printing, the first heat exchange medium can be oil, which has a high boiling point. By exchanging heat between the oil and the high-temperature tail gas in the first heat exchange pipeline 601, the temperature of the oil after heat exchange after flowing to the heating device 10 is about 180°C, which can meet the heating requirements of the ink. In addition, since the temperature of the first heat exchange medium needs to reach about 180°C, using oil as the first heat exchange medium can avoid the first heat exchange medium from gasifying to form gas in the first heat exchange pipeline 601, and can reduce the generation of bubbles in the first heat exchange pipeline 601, thereby avoiding the heat exchange efficiency of the first heat exchanger 60 from being affected. Of course, in other embodiments, when the organic waste gas treatment system 100 is used to heat other types of organic materials, the first heat exchange medium can also be replaced by water or other types of media to meet the use requirements of the waste gas treatment system.

[0038] In addition, since the ink and the organic waste gas generated by the ink are both combustibles, compared with setting an electric heater in the heating device 10, using oil to heat the ink in the heating device 10 is safer and the temperature in the heating device 10 is easier to control, thereby improving the product quality when the ink is printed.

[0039] Therefore, by circulating the first heat exchange medium between the first heat exchange pipeline 601 and the first heating pipeline 101, the heat of the high-temperature exhaust gas can be transferred to the heating device 10, so that the heating device 10 can heat the organic material to produce organic waste gas. Compared with the prior art, the external energy required for the heating device 10 to heat the organic material can be reduced, and the utilization rate of the waste heat of the high-temperature exhaust gas can be improved, thereby reducing the production energy consumption of the processing plant.

[0040] Reference Figure 1 and Figure 2 In some embodiments of the present application, the organic waste gas treatment system 100 may further include: a first liquid storage component 710 and a first hydraulic component 720, both of which are connected between the first heat exchange pipeline 601 and the first heating pipeline 101, and the first liquid storage component 710 is used to store the first heat exchange medium. In some specific embodiments, the first liquid storage component 710 may be an oil storage tank, but the present application is not limited thereto. For example, the first liquid storage component 710 may also be an oil tank or an oil storage tank. By using the first liquid storage component 710 to store the first heat exchange medium, the heat storage amount of the first heat exchange medium in the organic waste gas treatment system 100 can be increased. When the concentration of the organic waste gas fluctuates greatly and the temperature of the high-temperature waste gas fluctuates greatly, the temperature change of the first heat exchange medium can be reduced, thereby improving the temperature stability of the first heat exchange medium.

[0041] Furthermore, the first hydraulic component 720 is used to drive the first heat exchange medium to flow between the first heat exchange pipeline 601 and the first heating pipeline 101. The first hydraulic component 720 may be a vane pump or a plunger pump, etc. By arranging the first hydraulic component 720 between the first heat exchange pipeline 601 and the first heating pipeline 101, the technical effect of continuously transferring the heat of the high-temperature exhaust gas to the heating device 10 can be achieved.

[0042] Reference Figure 1 and Figure 2 In some embodiments of the present application, the organic waste gas treatment system 100 may further include: a first control valve 730, a first temperature detection member 740 and a controller, wherein the first control valve 730 is disposed between the first heat exchange pipeline 601 and the first heating pipeline 101, wherein the first control valve 730 may be a solenoid valve, and when the first control valve 730 is opened, the first control valve 730 connects the first heat exchange pipeline 601 and the first heating pipeline 101, and the first heat exchange medium can circulate between the first heat exchange pipeline 601 and the first heating pipeline 101. Moreover, by adjusting the opening of the first control valve 730, the flow of the first heat exchange medium between the first heat exchange pipeline 601 and the first heating pipeline 101 can be adjusted.

[0043] The first temperature detection member 740 may be disposed on the first heating pipeline 101 and used to detect the temperature of the first heating pipeline 101, wherein the first temperature detection member 740 may be an infrared temperature sensor, the first control valve 730 and the first temperature detection member 740 are both connected to the controller in communication, and the controller is configured to control the first control valve 730 to open or close according to the detection signal of the first temperature detection member 740, so as to adjust the flow of the first heat exchange medium between the first heat exchange pipeline 601 and the first heating pipeline 101. For example, when the organic waste gas treatment system 100 is used to treat organic waste gas generated by ink printing, the heating temperature of the first heating pipeline 101 should be maintained at 170°C to 180°C, and when the heating temperature of the first heating pipeline 101 is lower than 170°C, the controller may control the opening of the first control valve 730 to increase according to the detection signal of the first temperature detection member 740, so as to increase the flow of the first heat exchange medium between the first heat exchange pipeline 601 and the first heating pipeline 101.

[0044] Alternatively, when the heating temperature of the first heating pipeline 101 is higher than 170°C, the controller can control the opening of the first control valve 730 to decrease according to the detection signal of the first temperature detection component 740 to reduce the flow rate of the first heat exchange medium between the first heat exchange pipeline 601 and the first heating pipeline 101.

[0045] Reference Figure 1 and Figure 2 In some embodiments of the present application, the combustion chamber 20 may be provided with a concentration detection element 203 and a gas control valve 204. The concentration detection element 203 may be a concentration meter, and the gas control valve 204 may be a solenoid valve. The concentration detection element 203 and the gas control valve 204 are both connected to the controller for communication. The concentration detection element 203 is used to detect the concentration of the organic waste gas in the combustion chamber 20. The controller is also configured to control the opening of the gas control valve 204 according to the detection signal of the concentration detection element 203 to adjust the gas flow between the combustion chamber 20 and the gas pipeline 40. When the concentration of the organic waste gas is too low and does not meet the combustion requirements of the organic waste gas, the controller controls the opening of the gas control valve 204 to increase, and the gas flow into the combustion chamber 20 is larger, so that the concentration of the combustible gas in the combustion chamber 20 can be increased, so that the gas in the combustion chamber 20 can be ignited smoothly.

[0046] When the concentration of organic waste gas gradually increases, the controller controls the opening of the gas control valve 204 to decrease, and the gas flow rate flowing into the combustion chamber 20 is smaller. Under the condition that the gas in the combustion chamber 20 can be burned smoothly, the gas consumption can be reduced, thereby reducing the operating cost of the organic waste gas treatment system 100. Further, when the concentration of organic waste gas is high enough, the controller can control the gas control valve 204 to be completely closed. At this time, the organic waste gas treatment system 100 can operate automatically without consuming gas, which can further reduce the energy consumption of the factory in treating organic waste gas, thereby helping the factory to achieve energy conservation and emission reduction.

[0047] Furthermore, the controller is also configured to control the opening of the gas control valve 204 according to the detection signal of the first temperature detection member 740 to adjust the gas flow between the combustion chamber 20 and the gas pipeline 40. Among them, the organic material needs to be heated and treated within a preset heating temperature range. When the organic waste gas treatment system 100 is initially started and the temperature of the first heat exchange medium flowing into the first heating pipeline 101 is lower than the preset heating temperature range, the opening of the gas control valve 204 is increased by controlling the controller, and the gas flow into the combustion chamber 20 increases. The heat generated by the combustion of the combustible gas in the combustion chamber 20 is more, and the heat transferred to the first heat exchange medium through the first heat exchanger 60 is more, which helps to accelerate the temperature rise of the first heat exchange medium, and then the temperature of the first heat exchange medium flowing into the first heating pipeline 101 can reach the preset heating temperature range faster.

[0048] Furthermore, when the temperature of the first heat exchange medium flowing to the first heating pipeline 101 exceeds a preset heating temperature range, the controller controls the opening of the gas control valve 204 to decrease, the gas flow rate flowing into the combustion chamber 20 is reduced, the heat generated by the combustion of the combustible gas in the combustion chamber 20 is less, and the heat transferred to the first heat exchange medium through the first heat exchanger 60 is less, thereby reducing the temperature of the first heat exchange medium flowing to the first heating pipeline 101 to the preset heating temperature range.

[0049] Reference Figure 1 and Figure 2 In some embodiments of the present application, the organic waste gas treatment system 100 may further include: a second heat exchanger 810, which may be arranged in the exhaust pipe 50, and along the exhaust direction of the exhaust pipe 50, the second heat exchanger 810 may be arranged on the downstream side of the first heat exchanger 60, that is, after the exhaust gas formed by combustion in the combustion chamber 20 is heat exchanged with the first heat exchange medium in the first heat exchanger 60, the exhaust gas after heat exchange can flow to the second heat exchanger 810.

[0050] In addition, a second heat exchange pipeline 811 is provided in the second heat exchanger 810, and the second heat exchange pipeline 811 is suitable for allowing the second heat exchange medium to flow through, and the second heat exchange pipeline 811 is used to exchange heat with the exhaust pipe 50. By making the second heat exchanger 810 exchange heat with the exhaust gas in the exhaust pipe 50, the waste heat of the exhaust gas in the exhaust pipe 50 can be further utilized, so as to further improve the heat utilization rate in the exhaust gas generated by the organic waste gas treatment system 100. In some specific embodiments, the second heat exchange medium can be water or other media, and the second heat exchange medium can be used to provide heat for other processing equipment in the processing plant. When the second heat exchange medium is water, the heat in the exhaust gas heats the water, and the hot water can also be used for daily use, such as for drinking or bathing, etc., so that the daily operating costs of the processing plant can be further reduced.

[0051] In some embodiments, when the second heat exchange medium is water, the liquid inlet end of the second heat exchanger 810 is suitable for being connected to or blocked with a tap water pipe, and the liquid outlet end of the second heat exchanger 810 can be connected to a water outlet pipe. When hot water is needed and exhaust gas flows through the exhaust pipe 50, the tap water can flow from the tap water pipe to the second heat exchanger 810 by opening the water outlet valve of the tap water pipe. After the tap water exchanges heat with the exhaust gas, the heated hot water can flow out through the water outlet pipe for daily use.

[0052] However, the present application is not limited thereto. In other embodiments, for example, Figure 1 In the illustrated embodiment, the organic waste gas treatment system 100 may further include: a second liquid storage component 820 and a second hydraulic component 830, wherein the second liquid storage component 820 has a first liquid inlet 821 and a first liquid outlet 822 and is used to store a second heat exchange medium (i.e., water or other medium), wherein the second liquid storage component 820 may be a liquid storage tank or a liquid storage barrel, etc. The first liquid inlet 821 is connected to the liquid outlet end of the second heat exchange pipeline 811, and the first liquid outlet 822 is connected to the liquid inlet end of the second heat exchange pipeline 811, and the second hydraulic component 830 is disposed between the second heat exchange pipeline 811 and the second liquid storage component 820 and is used to drive the second heat exchange medium to circulate between the second heat exchange pipeline 811 and the second liquid storage component 820.

[0053] By setting a second liquid storage component 820 in the organic waste gas treatment system 100, and using the second hydraulic component 830 to drive the second heat exchange medium to circulate between the second heat exchange pipeline 811 and the second liquid storage component 820, the second heat exchange medium in the second liquid storage component 820 can pre-store the heat in the exhaust gas. When the user needs to use the heated second heat exchange medium, the second liquid storage component 820 can provide the user with the heated second heat exchange medium, thereby making the heated second heat exchange medium more flexible to use, thereby improving the user experience of the organic waste gas treatment system 100.

[0054] Reference Figure 1 and Figure 2 In some embodiments of the present application, the organic waste gas treatment system 100 may also include: a first liquid inlet pipe 840, a second temperature detection component 850 and a controller, one end of the first liquid inlet pipe 840 is connected to the second liquid storage component 820, the first liquid inlet pipe 840 is provided with a second control valve 841, and the other end of the first liquid inlet pipe 840 is suitable for connecting to an external liquid storage device, the external liquid storage device is used to provide a second heat exchange medium. In some specific embodiments, when the second heat exchange medium is clean water, the external liquid storage device can be a tap water pipe or a water tank.

[0055] That is, by controlling the second control valve 841 to be opened, the second control valve 841 can make the first liquid inlet pipe 840 connect to the external liquid storage device and the second liquid storage component 820, so that the water pipe or water tank can provide clean water to the second liquid storage component 820. By controlling the second control valve 841 to be closed, the second control valve 841 can make the first liquid inlet pipe 840 block the external liquid storage device and the second liquid storage component 820, so that the water pipe or water tank cannot provide clean water to the second liquid storage component 820.

[0056] The second temperature detection component 850 is arranged in the second liquid storage component 820 and is used to detect the temperature of the second heat exchange medium in the second liquid storage component 820. The second temperature detection component 850 can be a temperature sensor. The second temperature detection component 850 and the second control valve 841 are both communicatively connected to the controller, that is, the controller can control the second control valve 841 to be opened or closed, and the controller is constructed to control the second control valve 841 to be connected or blocked according to the detection signal of the second temperature detection component 850.

[0057] Among them, when the second heat exchange medium provided by the external liquid storage device is lower than the preset temperature range of the second heat exchange medium in the second liquid storage component 820, and the temperature of the second heat exchange medium in the second liquid storage component 820 has not reached the preset temperature range, the second control valve 841 is closed by the controller, and the external liquid storage device cannot provide the low-temperature second heat exchange medium to the second liquid storage component 820. In this way, the temperature of the second heat exchange medium in the second liquid storage component 820 can be gradually increased until the temperature of the second heat exchange medium in the second liquid storage component 820 reaches the preset temperature range.

[0058] Furthermore, when the temperature of the second heat exchange medium in the second liquid storage component 820 exceeds the preset temperature range, the second control valve 841 is opened by the controller, and the external liquid storage device can provide a low-temperature second heat exchange medium to the second liquid storage component 820, so that the temperature of the second heat exchange medium in the second liquid storage component 820 can be gradually reduced until the temperature of the second heat exchange medium in the second liquid storage component 820 is reduced to the preset temperature range, so that the temperature of the second heat exchange medium in the second liquid storage component 820 can meet the user's usage requirements.

[0059] According to some specific embodiments of the present application, the second liquid storage component 820 is also connected to a water outlet pipe, and the liquid in the second liquid storage component 820 can be supplied to the user through the water outlet pipe.

[0060] In some other embodiments, see Figure 2 When the second heat exchange medium is oil, the organic waste gas treatment system 100 may further include: a third liquid storage component 910, a third hydraulic component 920 and a second heating pipeline 930. The third liquid storage component 910 is used to store the third heat exchange medium. At this time, the third heat exchange medium may be clean water. The second heating pipeline 930 is arranged in the third liquid storage component 910. The third liquid storage component 910 may be a water storage tank, etc. The liquid inlet end of the second heating pipeline 930 is connected to the liquid outlet end of the second heat exchange pipeline 811, and the liquid outlet end of the second heating pipeline 930 is connected to the liquid inlet end of the second heat exchange pipeline 811. The third hydraulic component 920 is arranged between the second heating pipeline 930 and the second heat exchange pipeline 811 and is used to drive the second heat exchange medium to circulate between the second heating pipeline 930 and the second heat exchange pipeline 811.

[0061] By allowing the oil to exchange heat with the exhaust gas in the exhaust pipe 50 in the second heat exchange pipeline 811, the oil can absorb the heat of the exhaust gas in the exhaust pipe 50 and transfer it to the oil, and then the oil flows into the second heating pipeline 930 to exchange heat with the clean water to heat the clean water, that is, the heat in the exhaust gas can be indirectly transferred to the third heat exchange medium through the second heat exchange medium, wherein the boiling point of the oil is higher than the boiling point of the clean water, when the exhaust gas temperature in the exhaust pipe 50 is high, the oil in the second heat exchange pipeline 811 is not easy to gasify, and the generation of bubbles in the second heat exchange pipeline 811 can be avoided as much as possible to affect the heat exchange efficiency of the second heat exchange pipeline 811. In addition, when the second heat exchange pipeline 811 leaks, the second heat exchange medium is used to exchange heat between the exhaust gas and the third heat exchange medium, which can effectively prevent the residual toxic substances in the exhaust gas from penetrating into the third heat exchange medium.

[0062] Reference Figure 1 and Figure 2In some embodiments of the present application, the organic waste gas treatment system 100 may further include: a second liquid inlet pipe 940, a third temperature detection component 950 and a controller, one end of the second liquid inlet pipe 940 is connected to the third liquid storage component 910, the second liquid inlet pipe 940 may be provided with a third control valve 941, and the other end of the second liquid inlet pipe 940 is suitable for being connected to an external liquid storage device, and the external liquid storage device is used to provide a third heat exchange medium, wherein, in some specific embodiments, the external liquid storage device may be a water storage tank or a tap water pipeline, etc. When the third control valve 941 is opened, the liquid inlet pipe connects the external liquid storage device and the third liquid storage component 910, and the third heat exchange medium can be added into the third liquid storage component 910. And when the third control valve 941 is opened, the liquid inlet pipe blocks the external liquid storage device and the third liquid storage component 910, and the third heat exchange medium cannot be added into the third liquid storage component 910.

[0063] The third temperature detection component 950 can be arranged in the third liquid storage component 910 and is used to detect the temperature of the third heat exchange medium in the third liquid storage component 910. The third temperature detection component 950 and the third control valve 941 are both connected to the controller in communication, and the controller is configured to control the third control valve 941 to be connected or blocked according to the detection signal of the third temperature detection component 950. The temperature of the third heat exchange medium in the third liquid storage component 910 is different from the temperature of the third heat exchange medium provided by the external liquid storage device. By controlling the third control valve 941 to be connected or blocked by the controller, the third heat exchange medium can be selectively flowed into the third liquid storage component 910, thereby increasing the temperature of the third heat exchange medium in the third liquid storage component 910, and further making the temperature of the third heat exchange medium provided to the user by the third liquid storage component 910 more suitable, and further improving the user experience of the organic waste gas treatment system 100.

[0064] According to some specific embodiments of the present application, the third liquid storage component 910 is also connected to a water outlet pipe, and the liquid in the third liquid storage component 910 can be supplied to the user through the water outlet pipe.

[0065] 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.
