Description

Technical Field

[0001] This invention relates to the field of heat fluid generator technology, and in particular to a multi-chamber, multi-element heat fluid generator. Background Technology

[0002] Heavy oil extraction refers to the extraction and production of dense, high-viscosity crude oil stored underground. Multi-electrode thermal fluid generators play a crucial role in heavy oil extraction. They primarily improve the fluidity of crude oil by generating thermal fluids, thereby increasing extraction efficiency and production. In heavy oil extraction, multi-electrode thermal fluid generators can reduce the viscosity of crude oil by heating it, making it easier to flow. This can be achieved by injecting hot water or steam downhole, thus improving the fluidity of the crude oil.

[0003] However, existing multi-fuel thermal generators can usually only use a single fuel such as diesel, which cannot meet production needs. When other fuels are required, or when different types of fuels are loaded into the various chambers of the multi-fuel thermal generator, the rate at which the fuels produce gas varies due to the physical properties of the fuels. If the water injection volume is not adjusted to follow the gas production rate, the water vapor content in the mixed gas will be unstable. In other words, the water injection volume cannot be adaptively adjusted with changes in fuel, and the water vapor content in the mixed gas produced by combustion cannot be controlled.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Reference Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a multi-chamber multi-element hot fluid generator. The multi-chamber multi-element hot fluid generator includes a housing 100, a spray assembly 200, and a steam control assembly 300. The housing 100 is the installation location for each component and provides a reaction site for combustion and gasification. The spray assembly 200 is used to provide mist-like water, and the steam control assembly 300 is used to automatically adjust the steam content according to different types of fuel.

[0032] Specifically, the housing 100 is provided with at least one combustion chamber 102 and a gasification chamber 101 from left to right. The gasification chamber 101 is connected to the combustion chamber 102. The combustion chamber 102 is used to provide a place for the combustion reaction of fuel. After the fuel is burned in the combustion chamber 102, a mixed gas is produced. The mixed gas then enters the gasification chamber 101. The left end of the housing 100 is the head end and the right end of the housing 100 is the tail end. The head and tail ends of the housing 100 are respectively provided with a fuel inlet 103 and a gas outlet 104. The fuel inlet 103 is connected to the combustion chamber 102 and the gas outlet 104 is connected to the gasification chamber 101. The fuel enters the combustion chamber 102 through the fuel inlet 103 and is burned. The high-temperature mixed gas produced by the combustion enters the gasification chamber 101 and is then discharged through the gas outlet 104.

[0033] Preferably, the spray assembly 200 includes a coil 201 disposed within the housing 100. The coil 201 passes through the combustion chamber 102 and the vaporization chamber 101 from left to right. The coil 201 is hollow and is used for the flow of water. Multiple nozzles 202 are provided on the coil 201 and are located in the vaporization chamber 101. The water flows in the coil 201. When the water passes through the combustion chamber 102, it is heated by the combustion chamber 102, thereby preheating the water. When the water flows through the nozzles 202, it is sprayed out from the nozzles 202 and forms a spray. The sprayed water is rapidly vaporized under the action of the high-temperature mixed gas and is fully mixed with the high-temperature mixed gas, increasing the water vapor content in the high-temperature mixed gas after ignition and combustion, and further improving the oil production efficiency.

[0034] It is worth noting that, since different types and properties of fuel produce gas at different rates during combustion, the internal pressure in combustion chamber 102 varies when different types and properties of fuel are burned. If a nozzle 202 with a constant injection volume is used, it will be impossible to adaptively adjust the injection volume of water, and it will be impossible to meet the requirement of maintaining a relatively stable ratio of water vapor content in the mixed gas under different types and properties of fuel.

[0035] Furthermore, the steam control assembly 300 includes a switch 301, a transmission component 302, and a sensing block 303; the switch 301 is inserted into the coil 201 and is adapted to regulate the water flow rate in the coil 201. By controlling the water flow rate in the coil 201, the water pressure in the coil 201 can be controlled, thereby controlling the injection volume at the nozzle 202; the transmission component 302 is rotatably installed in the housing 100, and the sensing block 303 is elastically installed in the combustion chamber 102. The sensing block 303 is connected to the transmission component 302, and the transmission component 302 is connected to the switch 301.

[0036] When different fuels burn in the combustion chamber 102, they produce mixed gases at different pressures. The mixed gases compress the sensing block 303, which drives the transmission component 302 to rotate. The transmission component 302 drives the switch component 301 to adjust the opening of the switch component 301 according to the internal pressure in the combustion chamber 102, thereby automatically adjusting the water pressure of the coil 201, and then automatically adjusting the water spray volume at the nozzle 202, and finally automatically adjusting the water vapor content in the mixed gas.

[0037] Example 2

[0038] Reference Figures 1 to 8 This is the second embodiment of the present invention, which is based on embodiment 1.

[0039] Specifically, in this embodiment, there are three combustion chambers 102, the central axes of the three combustion chambers 102 are parallel, and the three combustion chambers 102 are evenly arranged around the circumference of the housing 100. There are three fuel inlets 103, and the three fuel inlets 103 are arranged one-to-one with the three combustion chambers 102, that is, each combustion chamber 102 is provided with a fuel inlet 103, and fuel enters the corresponding combustion chamber 102 through the fuel inlet 103.

[0040] Preferably, the end of the housing 100 that has the fuel inlet 103 is also provided with an oxidizer inlet 105. There are three oxidizer inlets 105, and the three oxidizer inlets 105 are arranged one-to-one with the three combustion chambers 102. That is, each combustion chamber 102 has an oxidizer inlet 105, and the oxidizer inlet 105 is connected to the fuel inlet 103. The oxidizer inlet 105 is used to fill in air, oxygen-enriched or pure oxygen.

[0041] Preferably, the end of the housing 100 with the fuel inlet 103 is also provided with an ignition switch 106. There are three ignition switches 106, and the three ignition switches 106 are arranged in a one-to-one correspondence with the three combustion chambers 102. That is, each combustion chamber 102 is provided with an ignition switch 106, and the ignition switch 106 is connected to the combustion chamber 102.

[0042] Preferably, the coil 201 is spiral in shape, and the spiral axis of the coil 201 coincides with the central axis of the housing 100. The coil 201 is hollow inside, and the end of the coil 201 near the fuel inlet 103 is the water inlet 203, and the end of the coil 201 near the gas outlet 104 is the water outlet 204. Water enters the coil 201 from the water inlet 203, and after being heated by the combustion chamber 102, the water is sprayed out by the nozzle 202. Excess water flows out of the coil 201 from the water outlet 204. The coil 201 includes a preheating section 201a and a spray section 201b. The preheating section 201a is correspondingly arranged with the combustion chamber 102, and the spray section 201b is correspondingly arranged with the gasification chamber 101. The nozzle 202 is arranged on the spray section 201b.

[0043] Preferably, the housing 100 is provided with a mounting groove 107, the central axis of the mounting groove 107 coincides with the central axis of the housing 100, the mounting groove 107 is annular in shape, the inner diameter of the mounting groove 107 is greater than twice the inner diameter of the combustion chamber 102, and all three combustion chambers 102 are located in the inner ring of the mounting groove 107; the transmission component 302 includes a rotating ring 302a, which is rotatably installed in the mounting groove 107. There are three rotating rings 302a, which are arranged in parallel to each other. The central axis of the rotating ring 302a coincides with the central axis of the housing 100, and the three rotating rings 302a can rotate independently. A wedge-shaped groove 302b is provided on the inner peripheral wall of the rotating ring 302a.

[0044] Preferably, a groove 108 is provided on the inner peripheral wall of the combustion chamber 102, and the sensing block 303 is elastically installed in the groove 108. The sensing block 303 is adapted to slide along the depth direction of the groove 108. A connecting post 304 is provided at one end of the sensing block 303 away from the central axis of the combustion chamber 102. The connecting post 304 is adapted to extend into the mounting groove 107. When the fuel burns in the combustion chamber 102, the sensing block 303 slides in the groove 108 due to the internal pressure in the combustion chamber 102, and the connecting part moves synchronously with the sensing block 303. At the same time, when different types of fuels are burned in the combustion chamber 102, the displacement of the sensing block 303 is different. For example, when burning pulverized coal, diesel and natural gas, the displacement of the sensing block 303 is the smallest when burning pulverized coal, and the displacement of the sensing block 303 is the largest when burning natural gas.

[0045] Preferably, the end of the connecting post 304 located in the mounting groove 107 is provided with an arc portion 304a, and there are three sensing blocks 303. The three sensing blocks 303 are arranged one-to-one with the three rotating rings 302a. The arc portions 304a of the three connecting posts 304 respectively abut against the wedge grooves 302b of the three rotating rings 302a. When the fuel burns in the combustion chamber 102, the sensing blocks 303 are slid in the sliding groove 108 due to the internal pressure in the combustion chamber 102, which drives the connecting post 304 to move. The connecting post 304 cooperates with the wedge grooves 302b to drive the rotating rings 302a to rotate. The rotating rings 302a rotate relative to the central axis of the rotating rings 302a. When different fuels are placed in the three combustion chambers 102 respectively, the rotation amount of the three rotating rings 302a is also different.

[0046] Preferably, the switch 301 is located at the water inlet 203 of the coil 201. The switch 301 includes a fixed block 301a, a first movable piece 301b, a second movable piece 301c, and a third movable piece 301d. The fixed block 301a is fixed inside the coil 201. The bottom of the fixed block 301a is provided with a first groove 301e. The first movable piece 301b is inserted into the first groove 301e. The bottom of the first movable piece 301b is provided with a second groove 301f. The second movable piece 301c is inserted into the second groove 301f. The bottom of the second movable piece 301c is provided with a third groove 301g. The third movable piece 301d is inserted into the third groove 301g.

[0047] Preferably, the top of the first movable piece 301b, the second movable piece 301c, and the third movable piece 301d are all provided with connecting ropes 301h. The connecting ropes 301h pass through the fixing block 301a and extend into the mounting groove 107. The three connecting ropes 301h are respectively connected to the three rotating rings 302a. When the rotating rings 302a rotate, they can pull the corresponding first movable piece 301b, the second movable piece 301c, or the third movable piece 301d through the corresponding connecting ropes 301h, thereby controlling the opening degree of the switch 301, thereby controlling the water flow rate in the coil 201, thus controlling the water pressure in the coil 201, and thus controlling the spray volume at the nozzle 202.

[0048] During use, different fuels are used in different combustion chambers 102, resulting in different rates of gas production during combustion in the combustion chambers 102. The three sensing blocks 303 drive the first movable plate 301b, the second movable plate 301c, and the third movable plate 301d to move respectively, thereby comprehensively controlling the opening degree of the switch 301, and thus controlling the water flow rate in the coil 201. By controlling the water flow rate in the coil 201, the water pressure in the coil 201 can be controlled, which in turn controls the injection volume at the nozzle 202.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
