Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection engineering, and particularly to a carbon dioxide emission reduction device for burning geothermal associated gas. Background Art

[0002] The carbon dioxide emission reduction device for burning geothermal associated gas is the core environmental protection equipment for the treatment of associated gas during the development of geothermal energy. When geothermal resources are exploited, greenhouse gases such as carbon dioxide are often released naturally. Direct emission will exacerbate the climate crisis. This device can significantly reduce the carbon footprint of the entire life cycle of geothermal energy by capturing, storing or converting the carbon dioxide escaping from the geothermal wellhead, upgrading traditional geothermal projects to a truly zero-carbon energy system.

[0003] Traditional emission reduction devices are widely used in the field of geothermal engineering. However, due to the limitations of their structures and working principles, there are often some problems that cannot be ignored. There is a problem of heat energy loss in the operation of traditional carbon dioxide emission reduction devices for burning geothermal associated gas. Geothermal associated gas usually contains combustible components such as methane and hydrogen sulfide. Traditional technologies mostly use the direct combustion method for treatment, converting methane into carbon dioxide through high-temperature oxidation to reduce the greenhouse effect. However, the waste heat generated in this process lacks an effective recovery system, resulting in a reduction in the thermal energy utilization rate of the geothermal field. This not only wastes the potential energy that could have been used for power generation or heating, but also increases the additional energy consumption of the cooling system. Moreover, separating carbon dioxide from the adsorbent requires additional equipment and processes, increasing the operating cost. Summary of the Invention

[0004] In view of the problems of heat energy loss and complex carbon dioxide separation process in the prior art, a carbon dioxide emission reduction device for burning geothermal associated gas is proposed.

[0005] Its purpose is to make full use of the heat energy generated by burning associated gas and reduce the steps of separating carbon dioxide from the adsorbent.

[0006] The technical solution of the present invention is a carbon dioxide emission reduction device for burning geothermal associated gas, which includes a housing, a base provided at the bottom of the housing, a separation mechanism provided inside the housing, and a circulation mechanism provided inside the housing;

[0007] The separation mechanism is used to separate carbon dioxide, and the circulation mechanism is used to regenerate the medium for absorbing carbon dioxide;

[0008] The separation mechanism includes a combustion chamber disposed at the bottom of the housing, an intake pipe disposed at the bottom of the combustion chamber, a spray chamber disposed in the middle of the housing, a connecting pipe disposed at the top of the combustion chamber, one end of the connecting pipe away from the combustion chamber is fixedly connected to the spray chamber, a spray pipe disposed at the top of the spray chamber, a plurality of nozzles arranged in an annular array at the bottom of the spray pipe, an orifice plate disposed in the middle of the spray chamber, an exhaust pipe disposed at the top of the spray chamber, a driving unit disposed at the top of the spray pipe for extracting the medium, and a heat exchange unit disposed on the outer side of the housing for heat exchange.

[0009] Further, the spray pipe is composed of a plurality of round pipes combined in a radial shape, and a plurality of nozzles are evenly arranged on different round pipes.

[0010] Further, the driving unit includes a partition disposed on the inner wall of the top of the housing, and a water pump disposed on the top of the partition.

[0011] Further, the heat exchange unit includes a housing disposed on the outer wall of the housing, a through hole opened at the top of the housing and penetrating to the bottom, a circulating water pipe disposed inside the through hole, and a return pipe sleeved outside the circulating water pipe, and the top of the return pipe is fixedly connected to the water pump.

[0012] Further, the outer shape of the return pipe is spiral, and the spiral diameter matches the diameter of the circulating water pipe.

[0013] Further, the circulating mechanism includes a fixing ring disposed in the middle of the combustion chamber, a heating kettle disposed in the middle of the fixing ring, the bottom of the return pipe is fixedly connected to the bottom of the heating kettle, a vertical pipe disposed on the side of the heating kettle away from the return pipe, the bottom of the vertical pipe is fixedly connected to the bottom of the spray chamber, and a collecting unit disposed at the rear of the heating kettle.

[0014] Further, the collecting unit includes an elbow disposed at the rear of the heating kettle, a round frame disposed in the middle of the elbow, a spring disposed on the side of the round frame away from the housing, a stopper disposed on the side of the spring close to the housing, and an airbag disposed on the side of the elbow away from the housing.

[0015] Further, a through hole penetrating from the rear to the front is opened at the rear of the round frame, the diameter of the stopper is larger than the diameter of the through hole and smaller than the inner diameter of the elbow, and the inner side of the heating kettle is corrugated.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a separation mechanism, the emission reduction device can actively intercept carbon dioxide after associated gas combustion. Utilizing the selective adsorption characteristics of the adsorbent, it isolates carbon dioxide from other gas components. The surface of the adsorbent combines with carbon dioxide molecules to achieve the separation of the target component in the gas mixture, facilitating subsequent compression storage or resource utilization. The remaining gas is released after purification, and the separated carbon dioxide can be injected into geological storage layers or converted into chemical raw materials, forming a closed-loop treatment chain and providing a feasible solution for the development of high-carbon geothermal fields.

[0018] 2. By setting up a circulation mechanism, the emission reduction device can directly apply the high-temperature waste heat generated by the combustion of associated gas to the adsorbent regeneration process, forming a continuous recycling mode, avoiding additional energy consumption. The heat energy in the high-temperature flue gas replaces the traditional electric heating or steam regeneration method, which not only reduces the system operation cost but also decreases the demand for external energy input. The application of the circulation mechanism extends the service life of the adsorbent and alleviates the problems of heat waste and material loss.

[0019] 3. By setting up a heat exchange unit, the emission reduction device can introduce the heat energy released by the combustion of associated gas into the geothermal circulation system. The heat is continuously transferred to the geothermal fluid, and the heated geothermal fluid is transported to the interior of the building through a pipeline network, providing a stable heat source for indoor heating. This not only avoids the direct emission loss of combustion heat energy but also reduces the dependence of building heating on fossil fuels. The geothermal circulation system improves the overall heat energy output efficiency by absorbing the heat energy from the combustion of associated gas and realizes the cascaded utilization of energy.

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0035] Example 1, referring to Figures 1 - 12 , which is the first embodiment of the present invention, provides a carbon dioxide emission reduction device for burning geothermal associated gas, including an outer shell 1, a base 2 fixedly connected to the bottom of the outer shell 1, and further including a separation mechanism 3 installed inside the outer shell 1 and a circulation mechanism 4 installed inside the outer shell 1; the separation mechanism 3 is used to separate carbon dioxide, and the circulation mechanism 4 is used to regenerate the medium for absorbing carbon dioxide; the separation mechanism 3 includes a combustion chamber 31 fixedly connected to the bottom of the outer shell 1, an intake pipe 32 fixedly connected to the bottom of the combustion chamber 31, a spray chamber 33 fixedly connected to the middle of the outer shell 1, a connecting pipe 34 fixedly connected to the top of the combustion chamber 31, one end of the connecting pipe 34 away from the combustion chamber 31 is fixedly connected to the spray chamber 33, a nozzle pipe 35 fixedly connected to the top of the spray chamber 33, a plurality of nozzles 36 fixedly connected to the bottom of the nozzle pipe 35 in an annular array, an orifice plate 37 fixedly connected to the middle of the spray chamber 33, an exhaust pipe 314 fixedly connected to the top of the spray chamber 33, a driving unit assembled on the top of the nozzle pipe 35 for extracting the medium, and a heat exchange unit assembled on the outside of the outer shell 1 for exchanging heat.

[0036] Specifically, the combustion chamber 31 can provide a space independent of the outside world to accommodate the flame during the combustion of associated gas and the gas after combustion. The associated gas can enter the interior of the combustion chamber 31 through the intake pipe 32. By igniting the associated gas at the top of the intake pipe 32, it can be burned. The spray chamber 33 can accommodate the sprayed polyethylene glycol dimethyl ether. The connecting pipe 34 can guide the gas after the combustion of the associated gas into the interior of the spray chamber 33. The polyethylene glycol dimethyl ether can flow inside the spray pipe 35 and be ejected through the nozzle, enabling the polyethylene glycol dimethyl ether to come into full contact with carbon dioxide, thereby adsorbing carbon dioxide. The orifice plate 37 can filter the waste gas after the combustion of the associated gas, prevent it from carrying particulate matter, and enable the waste gas to rise evenly through the micropores of the orifice plate 37. The waste gas after separation and filtration is discharged from the spray chamber 33 through the exhaust pipe 314. The emission reduction device can actively intercept carbon dioxide after the combustion of the associated gas, utilize the selective adsorption characteristics of polyethylene glycol dimethyl ether to isolate carbon dioxide from other gas components, combine the surface of the adsorbent with carbon dioxide molecules, and achieve the separation of the target component in the gas mixture, facilitating subsequent compression storage or resource utilization. The remaining gas is released after purification. The separated carbon dioxide can be injected into the geological storage layer or converted into chemical raw materials, forming a closed-loop treatment chain and providing a feasible solution for the development of high-carbon geothermal fields.

[0037] Refer to Figure 5 , the spray pipe 35 is composed of a number of circular pipes combined radially, and a number of nozzles 36 are evenly arranged on different circular pipes.

[0038] Specifically, the combination of the spray pipe 35 and the nozzle can enable the ejected polyethylene glycol dimethyl ether adsorbent to form a water curtain covering the cross-section of the spray chamber 33, so that the adsorbent can absorb carbon dioxide more fully.

[0039] Refer to Figure 2 , the drive unit includes a partition plate 38 fixedly connected to the inner wall of the top of the housing 1 and a water pump 39 fixedly connected to the top of the partition plate 38.

[0040] Specifically, the water pump 39 can pump out the adsorbent inside the heating kettle 42 and discharge the adsorbent through the spray pipe 35 and the nozzle.

[0041] Refer to Figures 2 - 8 , the heat exchange unit includes a housing 310 fixedly connected to the outer wall of the housing 1, a through hole 311 opened at the top of the housing 310 and penetrating to the bottom, a circulating water pipe 312 fixedly connected to the inner side of the through hole 311, and a return pipe 313 sleeved outside the circulating water pipe 312. The top of the return pipe 313 is fixedly connected to the water pump 39.

[0042] Specifically, the housing 310 can protect the circulating water pipe 312 and reduce heat loss. The circulating water pipe 312 plays a role in transferring heat in the geothermal system, transferring the underground heat to the surface. The return pipe 313 can circulate the heated adsorbent and transfer the heat of the adsorbent to the circulating water pipe 312. While the adsorbent dissipates heat, the waste heat can be utilized. After setting up the heat exchange unit, the emission reduction device can introduce the heat energy released by the combustion of associated gas into the geothermal circulation system. The heat is continuously transferred to the geothermal fluid. The heated geothermal fluid is transported to the interior of the building through the pipe network, providing a stable heat source for indoor heating, avoiding the direct emission loss of combustion heat energy, and reducing the dependence of building heating on fossil fuels. The geothermal circulation system absorbs the heat of the associated gas combustion, improves the overall heat energy output efficiency, and realizes the cascaded utilization of energy.

[0043] Referring to Figure 6 , the outer shape of the return pipe 313 is spiral, and the spiral diameter matches the diameter of the circulating water pipe 312.

[0044] Specifically, the spiral outer shape of the return pipe 313 increases the contact area with the circulating water pipe 312, thereby improving the heat exchange effect.

[0045] Example 2, referring to Figures 1 - 12 , is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the circulation mechanism 4 includes a fixed ring 41 fixedly connected to the middle of the combustion chamber 31, a heating kettle 42 fixedly connected to the middle of the fixed ring 41, the bottom of the return pipe 313 is fixedly connected to the bottom of the heating kettle 42, a vertical pipe 43 fixedly connected to the side of the heating kettle 42 away from the return pipe 313, the bottom of the vertical pipe 43 is fixedly connected to the bottom of the spray chamber 33, and a collection unit assembled at the rear of the heating kettle 42.

[0046] Specifically, the fixed ring 41 can fix the heating kettle 42 and divide the combustion chamber 31 into two relatively independent upper and lower spaces, avoiding the mixing of associated gas and waste gas. The adsorbent deposited at the bottom of the spray chamber 33 can enter the interior of the heating kettle 42 through the vertical pipe 43. The heating kettle 42 can accommodate the adsorbent after adsorbing carbon dioxide and heat the adsorbent with the flame of the associated gas combustion. Utilizing the characteristic that the adsorption capacity of polyethylene glycol dimethyl ether for carbon dioxide decreases with the increase of temperature, the carbon dioxide is separated from the adsorbent, enabling the adsorbent to be used again. After setting up the circulation mechanism 4, the emission reduction device can directly apply the high-temperature waste heat generated by the combustion of associated gas to the adsorbent regeneration link, forming a continuous circulation use mode, avoiding additional energy consumption. The heat energy in the high-temperature flue gas replaces the traditional electric heating or steam regeneration method, which not only reduces the system operation cost but also reduces the external energy input demand. The application of the circulation mechanism prolongs the service life of the adsorbent and alleviates the problems of heat waste and material loss.

[0047] Referring toFigures 9 - 12 , the collection unit includes an elbow 44 fixedly connected to the rear of the heating kettle 42, a circular frame 45 fixedly connected to the middle of the elbow 44, a spring 46 fixedly connected to the side of the circular frame 45 away from the housing 1, a stopper 47 fixedly connected to the side of the spring 46 close to the housing 1, and an airbag 48 fixedly connected to the side of the elbow 44 away from the housing 1.

[0048] Specifically, the density of the separated carbon dioxide in the heating kettle 42 is less than that of the adsorbent, so it will enter the elbow 44 located at the top of the heating kettle 42 and push the stopper 47 during the process of entering the elbow 44, releasing its seal on the elbow 44. After passing through the position of the stopper 47, the carbon dioxide enters the airbag 48 and is collected.

[0049] Refer to Figure 12 , a circular hole penetrating from the rear to the front is opened in the rear of the circular frame 45. The diameter of the stopper 47 is larger than the diameter of the circular hole and smaller than the inner diameter of the elbow 44. The inner side of the heating kettle 42 is corrugated.

[0050] Specifically, when the stopper 47 fits with the circular frame 45, it can block the elbow 44 to prevent the gas in the airbag 48 from leaking. The corrugated outer shape of the heating kettle 42 can increase the surface area, so as to increase the heating area of the heating kettle 42. The rest of the structure is the same as that of Embodiment 1.

[0051] In summary, the working principle of the present invention is as follows: after the equipment is installed, the bottom of the air inlet pipe 32 is connected to the associated gas, and the associated gas enters the combustion chamber 31 through the air inlet pipe 32. The associated gas is ignited at the top of the air inlet pipe 32 to make the associated gas burn. The flame position of the associated gas combustion is located on the inner side of the heating kettle 42. The associated gas produces waste gas such as carbon dioxide after combustion. As the combustion proceeds, the pressure in the combustion chamber 31 increases, and the waste gas after combustion enters the spray chamber 33 through the connecting pipe 34. The highest point of the connecting pipe 34 is close to the height of the spray chamber 33, which can prevent the adsorbent liquid level in the spray chamber 33 from being too high and entering the combustion chamber 31. Polyethylene glycol dimethyl ether is contained in the spray chamber 33 as an adsorbent, and the waste gas is The adsorbent absorbs a portion of carbon dioxide. As the exhaust gas continuously enters the spray chamber 33, the exhaust gas moves toward the top of the spray chamber 33 under the action of the pressure difference. During the movement, it is blocked and filtered by the orifice plate 37. The particulate matter in the exhaust gas will be filtered by the orifice plate 37, and the exhaust gas will pass through the orifice plate 37 evenly through the micropores on the orifice plate 37, and finally be discharged to the outside of the equipment through the exhaust pipe 314. When the exhaust gas passes through the spray chamber 33, the water pump 39 is started. The water pump 39 will extract the adsorbent located inside the heating kettle 42 through the reflux pipe 313, and spray the adsorbent through the spray pipe 35 and the nozzle 36. The adsorbent sprayed through several nozzles 36 will form a water curtain, which increases the contact area between the exhaust gas and the adsorbent, so that the adsorbent can be more fully The carbon dioxide is adsorbed, and the adsorbent is deposited at the bottom of the spray chamber 33 after eluting the exhaust gas. After the water pump 39 extracts the adsorbent in the heating kettle 42, the internal pressure of the heating kettle 42 decreases. At this time, the adsorbent deposited at the bottom of the spray chamber 33 will enter the interior of the heating kettle 42 through the vertical pipe 43. Since the flame burns inside the heating kettle 42, the heating kettle 42 transfers heat to the adsorbent inside. After the temperature of polyethylene glycol dimethyl ether increases, the adsorption force of carbon dioxide decreases, causing the carbon dioxide dissolved inside to precipitate. The separated carbon dioxide exists in the form of gas, so it will be above the liquid surface of the adsorbent. As the carbon dioxide precipitated from the adsorbent increases, the pressure in the heating kettle 42 increases, and the carbon dioxide will pass through the elbow 43. 4 enters the airbag 48 to be collected. In the process of passing through the curved pipe 44, the carbon dioxide will push the block 47 to move away from the housing 1, and the spring 46 will accumulate force while moving, so that the carbon dioxide can enter the airbag 48 through the gap between the block 47 and the curved pipe 44. After the pressure in the heating kettle 42 is reduced, the block 47 will fit with the round frame 45 under the action of the spring 46, so that the curved pipe 44 is blocked, so that the carbon dioxide in the airbag 48 will not flow back. The adsorbent in the heating kettle 42 will pass through the reflux pipe 313 when being pumped away by the water pump 39, and the adsorbent will be in a heated state when entering the reflux pipe 313. In the process of passing through the reflux pipe 313, the adsorbent will transfer its own heat flow to the reflux pipe 313.The return pipe 313 transfers heat to the circulating water pipe 312, and the thermal energy is transferred to the location where heat supply is required through the circulating water pipe 312, realizing the recovery and utilization of the thermal energy of the combustion associated gas. Moreover, the adsorbing capacity of the adsorbent after cooling is restored and it can be put into use again. By utilizing waste heat, the process of changing the pressure of the adsorbent in the traditional decarbonization method is reduced, achieving the goal of environmental protection and energy conservation.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
