Description

Technical Field

[0001] The present invention relates to the technical field of diesel generators, and in particular to a pipeline blockage self-checking diesel generator set. Background Art

[0002] A diesel generator mainly includes a diesel engine and a generator. Its operating principle is that the diesel engine burns diesel to generate heat energy, then converts the heat energy into mechanical energy, and finally the generator converts the mechanical energy into electrical energy.

[0003] In order to input clean air into the diesel engine, a filter is usually provided on the intake side of the diesel engine to filter out liquid droplets such as oil and water and particulate impurities such as dust in the air. As the use time increases, the intake resistance will increase. Seriously, it will cause the intake pipeline to be blocked. Therefore, sensors such as flow meters are usually also provided on the air filter on the intake side of the diesel generator set to detect the operating conditions of the intake pipeline. Before blockage, the oil, water, dust and other impurities attached to the surface of the filter element in the air filter are discharged in time to ensure the smoothness of the intake pipeline.

[0004] When the above-mentioned diesel generator set operates, although it can filter out impurities in the air, the main substance for the air to enter the diesel engine and undergo a combustion chemical reaction with diesel is oxygen. As an oxidizer, its volume fraction in the air is only 21%. That is, the concentration of the oxygen oxidizer in ordinary air is low. In high-altitude areas such as plateaus, the content of oxygen is even lower, resulting in incomplete combustion of diesel in the cylinder of the diesel engine, increasing diesel consumption, and increasing the content of harmful gases in the incomplete combustion, increasing the subsequent treatment burden. Moreover, the incomplete combustion makes the heat generated during combustion limited, and then the converted mechanical energy is limited, affecting the power generation efficiency.

[0005] In summary, due to the limited content of oxygen used in the combustion process, the power generation efficiency is reduced, the subsequent waste gas treatment cost and diesel consumption are increased, and the adverse impact on the environment also increases. Therefore, it is necessary to improve the diesel generator set in the prior art. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a pipeline blockage self-checking diesel generator set with energy conservation, environmental protection, improved diesel combustion efficiency, increased power generation and reduced subsequent waste gas treatment cost.

A cylindrical switching shell is provided between the three ends of the switching tee. A switching valve that is rotationally fitted with and sealed to its inner wall rotates in the switching shell. The switching valve has an L-shaped switching channel. The two ends of the channel are used to communicate with two of the ends of the switching tee.

Specific embodiments

[0041] The following combines the drawings and embodiments to further describe the specific embodiments of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0042] As Figure 1 - Figure 1As shown in Figure 8, a set of pipeline blockage self-checking diesel generators of the present invention includes a frame 1, and the following are provided on the frame 1:

[0043] A diesel engine 2 and a generator 3, the output end of the diesel engine 2 is connected to the input end of the generator 3, and the diesel engine 2 has a combustion-supporting inlet 21, an exhaust gas outlet 22 and a fuel inlet 23;

[0044] A fuel supply assembly 8 for delivering diesel to the fuel inlet 23;

[0045] An air supply assembly 4 for providing combustion-supporting gas to the combustion-supporting inlet 21, including an air compressor 41 and a filter 42 connected in sequence. A flow meter 43 is adjacent to the exhaust end of the filter 42, and a discharge valve 44 is connected to the bottom end;

[0046] An oxygen-increasing assembly, located between the filter 42 and the combustion-supporting inlet 21, for increasing the oxygen concentration in the combustion-supporting gas.

[0047] When the diesel generator set operates, external air is introduced into the oxygen-increasing assembly through the air supply assembly 4, and the oxygen-increasing assembly is used to perform oxygen-increasing treatment on the air to increase the oxygen concentration in the mixed gas, and output high-concentration oxygen, that is, combustion-supporting gas with an oxygen concentration higher than that in the external air, so that the combustion-supporting gas is delivered to the cylinder of the diesel engine 2 through the combustion-supporting inlet 21. At the same time, the fuel supply assembly 8 delivers diesel into the diesel engine 2 through the fuel inlet 23. The diesel engine 2 is internally provided with a high-pressure nozzle, and diesel droplets are output into the cylinder through the high-pressure nozzle, so that the diesel droplets burn in the cylinder inside the diesel engine 2. After generating heat energy, the output shaft of the diesel engine 2 is driven to rotate, that is, mechanical energy is generated, and the mechanical energy of the diesel engine 2 is converted into electrical energy by the generator 3, realizing the conversion of the chemical energy of diesel and oxygen into heat energy, the heat energy is converted into the mechanical energy of the rotation of the crankshaft of the diesel engine 2, and then the mechanical energy is converted into electrical energy.

[0048] During the above operation process, since an oxygen-increasing assembly is provided between the air supply assembly 4 and the diesel engine 2, most of the impurity gases in the air except the combustion-supporting gas of oxygen can be removed through the oxygen-increasing assembly, the oxygen concentration in the combustion-supporting gas is increased, and this concentration is significantly greater than the oxygen concentration in the external air, so that the diesel engine 2 has the following significant advantages when operating:

[0049] Firstly, it promotes a more complete combustion reaction. High-purity oxygen can provide more sufficient oxygen for diesel combustion, enabling elements such as carbon and hydrogen in diesel to more completely undergo combustion chemical reactions with oxygen, reducing the generation of incomplete combustion products (such as carbon monoxide, soot, etc.), making the combustion more complete and releasing more heat;

[0050] Second, improve the combustion efficiency. An environment with high-concentration oxygen will accelerate the speed of the combustion reaction, making the combustion process more intense. Correspondingly, the combustion temperature is higher, which helps the full combustion of diesel, converts more heat energy into mechanical energy, and then improves the power generation efficiency.

[0051] Third, reduce pollutant emissions. More complete combustion can significantly reduce the emissions of pollutants such as carbon monoxide, hydrocarbons, and particulate matter, which is beneficial to environmental protection, reduces the cost of post-treatment of exhaust gas, and realizes energy conservation and environmental protection.

[0052] Specifically, as Figure 1 - Figure 5 shown, the frame 1 includes a horizontal bottom plate 11. A horizontal top plate 12 is fixed directly above the bottom plate 11. The length directions of the bottom plate 11 and the top plate 12 are the same. One end of the bottom plate 11 is fixedly connected to the top plate 12 through a first bracket 13, and the other end of the bottom plate 11 is fixedly connected to the top plate 12 through a second bracket 14. A roller 15 is arranged below the bottom plate 11 to facilitate the movement of the equipment. A handle 16 is arranged at one end of the top plate 12 to facilitate pushing or pulling the equipment to move.

[0053] The diesel engine 2 and the generator 3 are both fixed above the bottom plate 11 and below the top plate 12. The operating process of the diesel engine 2 includes an intake stroke, a compression stroke, a power stroke, and an exhaust stroke that are executed cyclically, realizing the rotation of the crankshaft inside the diesel engine 2. The generator 3 converts the mechanical energy of the crankshaft rotation into electrical energy, which will not be elaborated here.

[0054] The air supply component 4 includes an air compressor 41. The air compressor 41 is fixed between the bottom plate 11 and the top plate 12. The intake end of the air compressor 41 is used to introduce external air, and the outlet end is connected with four filters 42 distributed in series in sequence. The filtration precisions of the four filters 42 at the outlet end of the air compressor 41 increase in sequence, mainly for gradually filtering impurities of different sizes in the air. That is, along the air flow path direction, the four filters 42 sequentially achieve primary filtration, secondary filtration, tertiary filtration, and quaternary filtration, and the sizes of the filtered impurities gradually decrease to ensure that clean air can be output to the oxygen increasing component. The four filters 42 are all arranged vertically, and their outlet ends are all connected with flow meters 43 and the bottoms are connected with discharge valves 44. After the flow meter 43 detects that the flow rate is lower than the preset value of the equipment, it indicates that there is a blockage in the pipeline. At this time, the discharge valve 44 is opened to facilitate the discharge of the impurities accumulated on the inner wall filter element of the filter 42.

[0055] The air supply assembly 4 further includes an aggregate pipe 46. The aggregate pipe 46 is fixed above the bottom plate 11 and extends along the length direction of the bottom plate 11. One end of the aggregate pipe 46 is closed, and a discharge valve 461 is provided at the other end. The aggregate pipe 46 is fixedly communicated with the chip discharge pipe at the bottom of the filter 42. After the discharge valve 44 is opened, the impurities filtered by the filter 42 can fall downward into the aggregate pipe 46. By regularly opening the discharge valve 461, the waste impurities collected in the aggregate pipe 46 can be discharged.

[0056] The oxygen enrichment assembly is arranged above the top plate 12. After receiving the clean air provided by the air supply assembly 4, it separates the oxygen and other gases (mainly nitrogen) in the air to increase the oxygen concentration in the air, so as to realize the full combustion of the diesel oil inside the diesel engine 2, reduce the diesel consumption, improve the combustion efficiency and power generation amount, reduce the emission of pollutants and reduce the cost of post-treatment of exhaust gas, and achieve energy conservation and environmental protection.

[0057] The fuel supply assembly 8 includes a fuel tank 81. The fuel tank 81 includes a box body with an open top and fixed on the bottom plate 11 and a box cover covering the box body, which is convenient for replenishing diesel into the box body. An observation window is provided on the box body to observe the remaining amount of diesel in the fuel tank 81. A fuel pump 82 is fixed above the box cover. The input end of the fuel pump 82 extends to the top inside the box body, and the output end is communicated with the fuel inlet 23. In this way, after the fuel pump 82 pumps the diesel in the fuel tank 81, it is transported to the cylinder of the diesel engine 2 through the fuel inlet 23 for mixing and combustion with high-concentration oxygen.

[0058] A storage battery 9 is also fixed on the bottom plate 11. The storage battery 9 is electrically connected to the generator 3 to store the electric energy generated by the generator 3.

[0059] A further improvement is that the oxygen enrichment assembly includes an oxygen enrichment unit 5. The oxygen enrichment unit 5 includes an oxygen enrichment shell 51 for replaceably filling oxygen-making molecular sieve. The oxygen enrichment shell 51 has inlets and outlets 52 provided at both ends of its inner cavity, which are respectively connected to the combustion-supporting inlet 21 and the filter 42.

[0060] By filling the oxygen-making molecular sieve in the oxygen enrichment shell 51, after the clean air filtered by the filter 42 passes through the oxygen enrichment shell 51, it contacts the oxygen-making molecular sieve in the oxygen enrichment shell 51. The oxygen-making molecular sieve adsorbs most of the nitrogen in the air, thereby increasing the oxygen concentration in the air passing through the inner cavity of the oxygen enrichment shell 51, so that the high-concentration oxygen can enter the diesel engine 2 for the diesel to burn fully, improve the power generation efficiency and reduce the pollutant emission. The oxygen-making molecular sieve can be replaceably placed in the hollow oxygen enrichment shell 51, which is convenient for timely replacement after the oxygen-making molecular sieve reaches the service life.

[0061] In the present invention, the oxygen-increasing unit 5 mainly relies on an oxygen-making molecular sieve to adsorb nitrogen in the air, so as to separate nitrogen and oxygen and improve the oxygen concentration in the air. Compared with other existing technologies, by using an oxygen-making molecular sieve to increase the oxygen concentration, the oxygen-increasing unit 5 is relatively small and compact, with a simple structure, occupying little space, and being convenient to install on the rack 1 with limited space. Moreover, the oxygen-making molecular sieve in the oxygen-increasing shell 51 can be replaced regularly, which is convenient for maintenance, so as to achieve long-term and efficient power generation of the present invention.

[0062] A further improvement is that the oxygen-increasing unit 5 further includes a swapping unit for swapping the connection states of the inlet and outlet 52 at both ends of the oxygen-increasing shell 51 with the combustion-supporting inlet 21 and the filter 42.

[0063] In the present invention, the two inlets and outlets 52 on the oxygen-increasing shell 51 are respectively located at both ends of the oxygen-increasing shell 51. For the convenience of distinction, the two inlets and outlets 52 are respectively defined as the first port and the second port. In the initial state, the first port is connected to the filter 42, and the second port is connected to the diesel engine 2. In the initial stage of operation of the oxygen-increasing unit 5, the clean air provided by the air supply assembly 4 enters the oxygen-increasing shell 51 through the first port, and is discharged through the second port and then enters the combustion-supporting inlet 21. After operating for a period of time (the specific time can be flexibly adjusted according to the user), the first port and the second port are swapped through the swapping unit, so that the first port is connected to the diesel engine 2 and the second port is connected to the filter 42. In this way, the clean air generated by the air supply assembly 4 enters the oxygen-increasing shell 51 through the second port and is discharged through the first port and then enters the combustion-supporting inlet 21. After the same period of time, the swapping assembly swaps the connection states of the first port and the second port with the filter 42 and the diesel engine 2 again.

[0064] After adopting the above method, the first port and the second port can be swapped regularly. In this way, the clean air can pass through the oxygen-increasing shell 51 along different paths. After the oxygen-increasing shell 51 is filled with molecular sieves, the positions of the molecular sieves remain fixed. Under different air flow paths, the air can contact different positions of the molecular sieves. Microscopically, both the side of the molecular sieve close to the first port and the side close to the second port can contact the air, so that the surface of the molecular sieve can fully and evenly absorb nitrogen in the air, increasing the amount of nitrogen in the air that can be adsorbed by each molecular sieve and increasing the adsorption amount, thereby extending the replacement cycle of the molecular sieve. Macroscopically, through the swapping unit, the air can enter the oxygen-increasing shell 51 from both sides of the oxygen-increasing shell 51 at different time periods and contact the oxygen-making molecular sieve. Compared with the prior art in which the intake side and the outlet side are fixed and more nitrogen is adsorbed on the intake side and less nitrogen is adsorbed on the outlet side, the oxygen-increasing unit 5 of the present invention enables the oxygen-making molecular sieve in the oxygen-increasing shell 51 to be fully and evenly absorbed, ensuring the uniformity and consistency of the overall adsorption of the oxygen-making molecular sieve inside the oxygen-increasing shell 51, further extending the service life of the molecular sieve and reducing the replacement frequency.

[0065] A further improvement is that the swapping unit includes a driving unit 53 and two swapping channels that are arranged side by side and respectively communicate with the inlet and outlet 52 at both ends of the oxygen-increasing shell 51. A swapping slider 54 that is in sealed fit with the circumferential inner wall thereof slides in both of the two swapping channels. The driving unit 53 drives the swapping sliders 54 in the two swapping channels to slide in opposite directions. The two ends of the two swapping channels are respectively connected to the combustion-supporting inlet 21 and the filter 42. The driving unit 53 includes a driving motor 531, a synchronous belt 532, and transmission wheels 533 corresponding to the two swapping channels one by one. The driving motor 531 is drivingly connected to one of the transmission wheels 533. The two transmission wheels 533 are drivingly connected through the synchronous belt 532 and are both coaxially connected with screws 534 having opposite thread directions. The screws 534 are in threaded cooperation with the swapping sliders 54.

[0066] Specifically, as Figure 8 - Figure 1 As shown in FIG. 2, the oxygen-increasing shell 51 includes a rectangular shell 511 with an open top. The shell 511 is fixed above the top plate 12. The two inlets and outlets 52 of the shell 511 extend outward to form rectangular inlet and outlet pipes. The inlet and outlet pipes extend along the length direction of the bottom plate 11. The two inlets and outlets 52 are distributed along the length direction of the bottom plate 11. Two partition plates 513 distributed along the length direction of the bottom plate 11 are fixed in the shell 511. The partition plates 513 are densely provided with mesh holes. The aperture of the mesh holes is smaller than the outer diameter of the oxygen-making molecular sieve. The oxygen-making molecular sieve is filled between the two partition plates 513 and the inner wall of the shell 511. The partition plates 513 are flush with the top of the shell 511 and are connected with an elastic sealing gasket 515. The sealing gasket 515 is a rubber gasket. A shell cover 512 is rotatably arranged above the shell 511. The shell cover 512 is connected with a locking unit 55. The locking unit 55 is used to lock the shell cover 512. In the locked state, the sealing gasket 515 is clamped between the shell cover 512 and the shell 511 and the partition plates 513. A discharge port located between the two partition plates 513 is arranged at the bottom of the shell 511. The connection port of the discharge port passes through the discharge pipe 5113 of the top plate 12. One end of the discharge pipe 5113 away from the discharge port is threadedly connected with a sealing plug 5114.

[0067] After adopting the above structure, when it is necessary to replace the oxygen-making molecular sieve, open the sealing plug 5114, and the oxygen-making molecular sieve located between the two partition plates 513 can be discharged. Then, after screwing the sealing plug 5114 tightly at the end of the discharge pipe 5113, release the locking of the shell cover 512 by the locking unit 55, which facilitates the upward rotation of the shell cover 512 to open the shell 511. Then, the oxygen-making molecular sieve can be replenished between the two partition plates 513 of the shell 511. After the replenishment is completed, rotate the shell cover 512 downward and lock the shell cover 512 through the locking unit 55, thereby completing the rapid replacement of the oxygen-making molecular sieve.

[0068] The oxygenation unit 5 further includes a return bucket 56 sleeved outside the housing 511 and fixed to the top plate 12. A return cover 57 is fixedly covered on the top of the return bucket 56. The two inlet and outlet pipes are fixedly connected to the return bucket 56. The return bucket 56 and the return cover 57 enclose a rectangular channel connected end to end in sequence. The rectangular channel is formed by combining a swapped channel arranged side by side and a connecting channel arranged side by side. The extending directions of the swapped channel and the connecting channel are parallel to the width direction and the length direction of the bottom plate 11 respectively. The two swapped channels are respectively fixedly connected to the two inlets and outlets 52. The two connecting channels are respectively fixedly connected to two inlet and outlet buckets 561. The two inlet and outlet buckets 561 are respectively connected to the filter 42 and the diesel engine 2.

[0069] The driving unit 53 further includes a driving housing 536 fixed to the outer side wall of the return bucket 56. The synchronous belt 532 and the two transmission wheels 533 are both arranged in the driving cavity formed by the driving housing 536 and the return bucket 56. The driving motor 531 is fixed to the outer side wall of the driving housing 536 and is coaxially fixedly connected to one of the transmission wheels 533. The two transmission wheels 533 are connected by the synchronous belt 532. The two transmission wheels 533 are respectively coaxially fixedly connected to two screw rods 534. The screw rods 534 are fixedly connected to the transmission wheels 533 through concentric shafts. The concentric shafts penetrate through the side wall of the return bucket 56 in a sealed manner. Bearings 535 are arranged at the ends of the two screw rods 534 away from the corresponding transmission wheels 533. The bearings 535, the screw rods 534 and the swapping sliders 54 are all located inside the return bucket 56. The swapping sliders 54 are sleeved outside the screw rods 534 in a sealed manner and are threadedly connected to the screw rods 534. The thread directions of the two screw rods 534 are opposite and the pitches are the same. The swapping sliders 54 are in sealed fit with the inner side wall of the return bucket 56 and the return cover 57. The inlet and outlet pipes are fixedly communicated between the inlets and outlets 52 and the inside of the return bucket 56. The housing cover 512 rotates above the return cover 57, and the axis of rotation is parallel to the width direction of the bottom plate 11. The two swapping sliders 54 are located on both sides of the axis of the inlet and outlet pipes.

[0070] After adopting the above structure, the driving motor 531 can drive one of the transmission wheels 533 to rotate, and the synchronous belt 532 is used to make the other transmission wheel 533 rotate. Since the screw rods 534 are coaxially fixedly connected to the transmission wheels 533, the two screw rods 534 rotate in opposite directions. And the thread directions of the two screw rods 534 are opposite, so that the two swapping sliders 54 move in opposite directions.

[0071] As shown in Fig. 11, among the two swapping sliders 54, the right swapping slider 54 is located above the axis line of the inlet / outlet 52, and the left swapping slider 54 is located below the axis line of the inlet / outlet 52. According to the positions of the two swapping sliders 54, clean air enters the lower left part of the connection channel from the left inlet / outlet barrel 561, passes through the lower docking channel, enters the oxygenation shell 51 through the lower left inlet / outlet pipe, contacts with the molecular sieve, and the combustion-supporting gas with increased oxygen concentration flows out from the upper right outlet pipe on the right side. After flowing downward through another docking channel and passing through the connection channel, it flows out from the inlet / outlet barrel 561 at the lower right corner and enters the diesel engine 2.

[0072] The driving unit 53 can realize the reverse movement of the two swapping sliders 54. At the same time, the two swapping sliders 54 are adjusted so that the right swapping slider 54 in the figure moves downward and the left swapping slider 54 moves upward. After the movement is completed, the air filtered and purified by the filter 42 enters the upper right part of the connection channel from the upper left inlet / outlet barrel 561, then slides downward along the right docking channel, passes through the right outlet pipe, passes through the oxygenation shell 51 in the reverse direction, then flows out from the left outlet pipe, enters the left docking channel and flows downward, then flows upward, and then passes through the lower part of the right connection channel, enters the lower inlet / outlet barrel 561 and then enters the diesel engine 2. (It should be noted that the up, down, left, and right in this paragraph are all in the reference direction shown in Fig. 11 and do not represent the actual up, down, left, and right directions).

[0073] A further improvement is that heat exchange tubes 514 with both ends respectively communicating with the waste gas outlet 22 and the outside are densely arranged in the oxygenation shell 51 to regenerate the oxygen-producing molecular sieve in the oxygenation shell 51; the air supply assembly 4 further includes a buffer tank 45. The buffer tank 45 includes an inner tank body 451 and a heating cylinder 452 fixedly sleeved on the inner tank body 451 and enclosing a heating chamber with the inner tank body 451. The inner tank body 451 is communicated between the filter 42 and the oxygenation assembly. The heating chamber is communicated with the waste gas outlet 22. Control valves 222 are arranged between the waste gas outlet 22 and both the heating chamber and the heat exchange tubes 514. The heating cylinder 452 is provided with a heating outlet 4522.

[0074] The specific structure of the heat exchange tubes 514 is as Figure 9 - Figure 1As shown in Fig. 2, the heat exchange tubes 514 extend along the length direction parallel to the bottom plate 11, are arrayed between the two partition plates 513, heat exchange ports 5111 are arranged on both sides of the housing 511, the heat exchange ports 5111 are through holes, and are in one-to-one correspondence and communication with the heat exchange tubes 514. Heat exchange shells 5112 are also fixed on both sides of the housing 511, and the heat exchange shells 5112 and the housing 511 enclose a heat exchange cavity. A heat exchange elbow pipe communicating with the heat exchange cavity is fixed above the heat exchange shells 5112. Among the heat exchange elbow pipes on the two heat exchange shells 5112, one is communicated with the outside, and the other is communicated with the exhaust gas outlet 22.

[0075] As Figure 3 and Figure 4 shown, in the air supply assembly 4, the buffer tank 45 is located on the side of the filter 42 away from the air compressor 41 and is fixed above the bottom plate 11. The inner tank body 451 of the buffer tank 45 is fixedly communicated with one of the inlet and outlet barrels 561 of the filter 42 and the oxygen enrichment shell 51. The heating inlet 4521 is arranged at the top of one side of the heating cylinder 452, and the heating outlet 4522 is arranged at the bottom of the other side of the heating cylinder 452. The exhaust gas outlet 22 of the diesel engine 2 is fixedly connected with two exhaust gas pipes 221. Two regulating valves 222 are arranged on the two exhaust gas pipes 221, and are respectively fixedly communicated with the heating inlet 4521 and the heat exchange shell 5112 of the oxygen enrichment shell 51.

[0076] The buffer tank 45 can temporarily store the clean air filtered by multiple filters 42, realize air flow buffering, and avoid the air transportation being too fast or too slow.

[0077] During the operation of the diesel engine 2, after the diesel and the combustion-supporting gas of high-concentration oxygen undergo a combustion chemical reaction, high-temperature exhaust gas is generated. Usually, the temperature of the exhaust gas is 300 - 500 °C, which is significantly high. By controlling the two regulating valves 222, the exhaust gas can be divided into two parts according to a set ratio. One part enters the heating cavity through the heating inlet 4521, and then exchanges heat with the clean air temporarily stored in the inner tank body 451 through the side wall of the inner tank body 451 to realize preheating of the clean air, and then is discharged from the heating outlet 4522; while the other part of the high-temperature exhaust gas can enter one of the heat exchange shells 5112, enter the heat exchange tubes 514 through the heat exchange ports 5111, and heat the oxygen production molecular sieve in the oxygen enrichment shell 51 through the tube wall of the heat exchange tubes 514 during the flow in the heat exchange tubes 514, and then enter the other heat exchange shell 5112 and is discharged from the heat exchange elbow pipe. That is, after the diesel engine 2 operates, the generated high-temperature exhaust gas can be used to heat the clean air about to enter the diesel engine 2 and the oxygen production molecular sieve in the oxygen enrichment shell 51.

[0078] When the high-temperature waste gas preheats the air before entering the diesel engine 2, it can increase the air temperature and decrease the density, so that when the diesel engine 2 operates, the atomized diesel can be better mixed with oxygen, promoting full combustion, thereby improving the thermal efficiency of the generator 3 of the present invention and reducing fuel consumption. Moreover, when preheating the air entering the diesel engine 2 in cold air, it also helps the startup of the generator 3, reducing the startup time and wear. In addition, using the preheating of the waste gas to preheat the intake air can realize the recycling and reuse of energy, improving the energy utilization rate of the entire device, meeting the requirements of energy conservation and environmental protection.

[0079] When the high-temperature waste gas passes through the heat exchange tube 514, it can heat the oxygen-making molecular sieve between the two partition plates 513, promoting the regeneration of the oxygen-making molecular sieve. After the regeneration is completed, it is convenient for the oxygen-making molecular sieve to continue adsorbing nitrogen, increasing the oxygen concentration in the air, forming an auxiliary combustion gas with high oxygen concentration, so as to achieve full combustion of the diesel inside the diesel engine 2, reduce pollutant emissions, lower the subsequent treatment cost, and improve the combustion efficiency and power generation efficiency.

[0080] A further improvement is that a spiral guide vane 5142 is fixed inside the heat exchange tube 514. The spiral guide vane 5142 and the inner wall of the heat exchange tube 514 enclose a spiral flow channel, and heat exchange fins 5141 are arranged on the outer side wall of the heat exchange tube 514 along its axial direction.

[0081] After adopting the above structure, the thermal contact area between the heat exchange tube 514 and the high-temperature waste gas and the oxygen-making molecular sieve is increased, and the heat exchange efficiency is improved. Moreover, through the enclosed spiral flow channel, the high-temperature waste gas can flow along a specific spiral trajectory, making it fully contact with the heat exchange tube 514, improving the heating efficiency, and thus promoting the regeneration of the oxygen-making molecular sieve.

[0082] A further improvement is that the oxygen-increasing component includes a switching unit 6 and two oxygen-increasing units 5. The switching unit 6 is used to switch the working states of the two oxygen-increasing units 5, so that the oxygen-increasing shell 51 of one of them is connected between the filter 42 and the auxiliary combustion inlet 21, and the molecular sieve in the oxygen-increasing shell 51 of the other is regenerated.

[0083] The two oxygen-increasing units 5 are closely arranged along the length direction of the bottom plate 11. By adjusting the operating states of the two oxygen-increasing units 5 through the switching unit 6, in one of the oxygen-increasing units 5, the oxygen-making molecular sieve in the oxygen-increasing shell 51 can adsorb the filtered clean air to form an auxiliary combustion gas with high oxygen concentration, improving the combustion efficiency, while facilitating the regeneration of the oxygen-making molecular sieve in the oxygen-increasing shell 51 of the other oxygen-increasing unit 5 to restore its nitrogen adsorption ability, and facilitating the subsequent adjustment of the operating states of the two oxygen-increasing units 5 by the switching unit 6, so that the diesel engine 2 can continuously introduce the auxiliary combustion gas with high oxygen concentration.

[0084] Therefore, by alternately using the above two oxygen enrichment units 5, it is possible to continuously supply oxygen-rich air with an oxygen concentration higher than that in the air to the diesel engine 2, ensuring that the diesel engine 2 can continuously and stably burn diesel, which helps to maintain the stable operation and high power generation efficiency of the generator 3; the two oxygen enrichment units 5 work alternately, enabling the work of adsorbing nitrogen to increase the oxygen concentration to be carried out continuously, avoiding the situation where the oxygen production molecular sieve in a single oxygen enrichment unit 5 cannot continue to adsorb nitrogen to increase the oxygen concentration after being saturated, and improving the overall oxygen enrichment efficiency and equipment utilization rate of the device.

[0085] A further improvement is that the switching unit 6 includes a switching three-way pipe 61 and a rotating unit 62. A cylindrical switching shell 611 is provided between the three ends of the switching three-way pipe 61. A switching valve 612 that is hermetically fitted to its inner wall is rotatably arranged in the switching shell 611. The switching valve 612 has an L-shaped switching channel 613. The two ends of the channel are used to communicate with two of the ends of the switching three-way pipe 61. The rotating unit 62 drives the switching valve 612 to rotate. There are four switching three-way pipes 61, which are respectively connected between the filter 42 and the two oxygen enrichment shells 51, between the combustion-supporting inlet 21 and the two oxygen enrichment shells 51, between the exhaust gas outlet 22 and the heat exchange pipes 514 corresponding to the two oxygen enrichment shells 51, and between the outside and the heat exchange pipes 514 corresponding to the two oxygen enrichment shells 51.

[0086] The specific structure diagram of the switching unit 6 is shown in FIGS. 13-16, and its connection structure with the two oxygen enrichment units 5 is as Figure 6 and Figure 7 shown. The switching unit 6 includes four switching three-way pipes 61. Each of the four switching three-way pipes 61 includes a cylindrical and hollow switching shell 611. The switching shell 611 is fixedly connected to a first pipe and two second pipes. The two second pipes are coaxial. The axis of the connection between the first pipe and the switching shell 611 is perpendicular to the axes of the two second pipes. To facilitate the distinction of the four switching three-way pipes 61, the four switching three-way pipes 61 are respectively defined as a combustion-supporting gas inlet three-way pipe 6101, a combustion-supporting gas outlet three-way pipe 6102, an exhaust gas inlet three-way pipe 6103, and an exhaust gas outlet three-way pipe 6104; as shown in FIGS. 16-18, switching valves 612 are arranged in the switching shells 611 of the four switching three-way pipes 61. The outer surface of the switching valve 612 is hermetically fitted to the upper and lower inner walls and the circumferential inner wall of the switching shell 611. An L-shaped switching channel 613 is arranged on the switching valve 612. The two ends of the switching channel 613 extend to the circumferential outer edge of the switching valve 612.

[0087] More specifically, for the combustion-supporting gas inlet three-way pipe 6101, its first pipe is fixedly communicated with the inner tank body 451, and the two second pipes respectively penetrate through the inlet and outlet barrels 561 on the same side of the oxygen-enriching shells 51 of the two oxygen-enriching units 5 in a sealed and fixed manner. Moreover, communication ports 614 are provided on the side walls of the two second pipes close to the ends, and the communication ports 614 are located inside the inlet and outlet barrels 561.

[0088] For the combustion-supporting gas outlet three-way pipe 6102, its first pipe is fixedly communicated with the combustion-supporting gas inlet 21, and the two second pipes respectively penetrate through the inlet and outlet barrels 561 on the other side of the oxygen-enriching shells 51 of the two oxygen-enriching units 5 in a sealed and fixed manner. Similarly, communication ports 614 are provided on the side walls of the two second pipes close to the ends, and the communication ports 614 are located inside the inlet and outlet barrels 561.

[0089] For the exhaust gas inlet three-way pipe 6103, its first pipe is fixedly communicated with the exhaust gas outlet pipe 221, and the two second pipes are respectively communicated with the heat exchange elbows of the heat exchange shells 5112 on the same side of the two oxygen-enriching shells 51; for the exhaust gas exhaust three-way pipe 6104, its first pipe is communicated with the outside, and the two second pipes are respectively communicated with the heat exchange elbows of the heat exchange shells 5112 on the other same side of the two oxygen-enriching shells 51.

[0090] For the two switching valves 612 corresponding to the combustion-supporting gas inlet three-way pipe 6101 and the combustion-supporting gas outlet three-way pipe 6102, one ends of the two switching channels 613 are respectively communicated with their first pipes, and the other ends face the same direction, and this direction is the first direction parallel to the length direction of the bottom plate 11; while for the two switching valves 612 corresponding to the exhaust gas inlet three-way pipe 6103 and the exhaust gas exhaust three-way pipe 6104, one ends of the two switching channels 613 are respectively communicated with their first pipes, and the other ends face the second direction, and the second direction is always opposite to the first direction.

[0091] After adopting the above structure, during the operation of the present invention, the clean air after filtration and preheating can enter the switching valve 612 through the first pipe of the combustion-supporting gas inlet three-way pipe 6101, be discharged along the first direction and enter one of the oxygen-enriching shells 51, and then enter the second pipe of the combustion-supporting gas outlet three-way pipe 6102 along the second direction, and enter the diesel engine 2 through the switching channels 613 of the switching valve 612 to burn with the atomized diesel.

[0092] After the combustion-supporting gas and diesel fuel burn, high-temperature exhaust gas is generated. The exhaust gas first enters the exhaust gas intake three-way pipe 6103, and then enters the heat exchange shell 5112 along the second direction through the switching channel 613 of the switching valve 612. After passing through the heat exchange pipe 514 in another oxygen-enriching shell 51, the oxygen-making molecular sieve in the oxygen-enriching shell 51 is heated and regenerated. Then it enters one of the second pipes of the exhaust gas exhaust three-way pipe 6104 and enters the switching shell 611 along the first direction. After passing through the switching channel 613, it is discharged to the outside. In this way, when the device is running, the oxygen-making molecular sieve in one of the oxygen-enriching shells 51 adsorbs nitrogen to increase the oxygen concentration, while the oxygen-making molecular sieve in the other oxygen-enriching shell 51 is regenerated.

[0093] By means of the rotating unit 62, the switching valves 612 of the four switching three-way pipes 61 can be driven to rotate simultaneously, so that among the four switching valves 612, the rotation directions of the two switching valves 612 corresponding to the combustion-supporting gas intake three-way pipe 6101 and the combustion-supporting gas outlet three-way pipe 6102 are opposite to the rotation directions of the remaining two switching valves 612, and the rotation speeds of the four switching valves 612 are the same, avoiding the complex structure of the equipment caused by setting multiple valves and the operation errors of the equipment caused by the opening and closing errors of the valves.

[0094] Specifically, the rotating unit 62 includes a rotating motor 621. The rotating motor 621 is fixed above the switching shell 611 of the exhaust gas intake three-way pipe 6103 and is arranged downward. Its output shaft is fixedly connected coaxially with the switching valve 612 in the switching shell 611. The rotating unit 62 also includes a chain 623 and two sprockets 622. The two sprockets 622 are respectively fixedly connected coaxially below the two switching valves 612 corresponding to the exhaust gas intake three-way pipe 6103 and the exhaust gas exhaust three-way pipe 6104. In this way, when the rotating motor 621 runs, it drives the switching valve 612 corresponding to the exhaust gas intake three-way pipe 6103 to rotate, and then through the chain 623 and the two sprockets 622 connected by transmission, the switching valve 612 corresponding to the exhaust gas exhaust three-way pipe 6104 rotates synchronously. The outer diameters of the two sprockets 622 are the same, so that the two switching valves 612 rotate in the same direction at the same speed.

[0095] Above the switching shells 611 corresponding to the two sprockets 622, two gears 624 that are meshed and have the same size are respectively arranged. Among the two pairs of gears 624, two of the gears 624 are annular and are fixedly connected coaxially with the two sprockets 622. The gears 624 have the same outer diameter as the sprockets 622. The remaining two gears 624 are respectively fixedly connected coaxially with the two switching valves 612 corresponding to the combustion-supporting gas intake three-way pipe 6101 and the combustion-supporting gas outlet three-way pipe 6102.

[0096] Due to the meshing design of the above-mentioned gear 624, the two switching valves 612 corresponding to the combustion-supporting gas inlet tee 6101 and the combustion-supporting gas outlet tee 6102 rotate in the opposite direction and at the same rotation rate as the two switching valves 612 corresponding to the exhaust gas inlet tee 6103 and the exhaust gas outlet tee 6104, ensuring the operation of the device. The clean air passes through one of the oxygen-enriching shells 51, and after increasing the oxygen concentration, it can, together with the high-temperature exhaust gas generated by the combustion of diesel, either pass through the other oxygen-enriching shell 51 for heating and regenerating the oxygen-making molecular sieve in the oxygen-enriching shell 51, or be introduced between the inner tank body 451 and the heating cylinder 452 to preheat the air, improving the combustion efficiency and achieving the full utilization of heat energy.

[0097] The two oxygen-enriching shells 51 are fixedly connected, and a sealing shell 63 is also fixedly connected between the two oxygen-enriching shells 51. The sealing shell 63 includes an upper shell cover 631 extending downward and two end shell covers 632 extending downward. Specifically, the bottom of the upper shell cover 631 is fixedly connected to the return-shaped covers 57 corresponding to the two oxygen-enriching units 5, and the top is hermetically and fixedly sleeved outside the two switching shells 611 corresponding to the exhaust gas inlet tee 6103 and the exhaust gas outlet tee 6104. The bottoms of the two end shell covers 632 are respectively fixed above the switching shells 611 corresponding to the combustible gas inlet tee and the combustible gas outlet tee, and the tops are fixedly connected to both ends of the bottom of the upper shell cover 631. The upper shell cover 631, the two end shell covers 632, and the two return-shaped covers 57 enclose a protection chamber, and the gear 624, the chain 623, and the sprocket 622 are all located in the protection chamber to ensure the stable operation of the rotating unit 62.

[0098] A positioning sleeve 633 with an axial direction parallel to the length direction of the bottom plate 11 is arranged above the upper shell cover 631. A locking sleeve 5121 is integrally formed on the shell cover 512. The shell covers 512 corresponding to the two oxygen-enriching units 5 are locked and connected to the positioning sleeve 633 through a locking unit 55. The locking unit 55 includes a locking bolt 551 and a locking nut 552 that are threadedly connected. After the shell cover 512 is hermetically covered on the shell body 511, the locking sleeve 5121 on the shell cover 512 is coaxial with the positioning sleeve 633. At this time, the rod portion of the locking bolt 551 is passed through the positioning sleeve 633 and the two locking sleeves 5121, and then the locking nut 552 is screwed on, so that the shell covers 512 of the two oxygen-enriching units 5 can be simultaneously locked and connected and hermetically covered on the two shell bodies 511. After the locking state is released, the two shell covers 512 can be conveniently opened to supplement the oxygen-making molecular sieve into the two shell bodies 511, making the operation more convenient.

[0099] A further improvement is that it further includes a cooling component 7. The cooling component 7 includes an air pump 71 and a cooling shell 72 communicated with the output end of the air pump 71. The cooling shell 72 has a nozzle 721 facing the diesel engine 2 and the generator 3. The air pump 71 has two input ends, one of which is communicated with the outside, and the other is communicated with two oxygenation shells 51 through a synchronous three-way pipe 73. A cylindrical synchronous shell 74 is arranged between the three ends of the synchronous three-way pipe 73. The synchronous valve 75 has an L-shaped synchronous channel 76. The two ends of the synchronous channel 76 are used for communicating with two of the ends of the synchronous three-way pipe 73. The synchronous valve 75 is fixedly connected coaxially with the switching valve 612 corresponding to the heat exchange pipe 514 and the outside.

[0100] Specifically, as Figure 6 , Figure 7 , shown in FIGS. 13-15, the intake end of the air pump 71 is connected to a cooling three-way pipe 77. The cooling three-way pipe 77 has two input pipes and an output pipe. The output pipe is communicated with the cooling shell 72 through the air pump 71. Among the two input pipes, one is communicated with the outside, and the other is communicated with two oxygenation shells 51 through a synchronous three-way pipe 73. A cooling three-way valve 771 is arranged on the cooling three-way pipe 77. The cooling three-way valve 771 is used to select one of the input pipes to communicate with the output pipe.

[0101] After adopting the above structure, the cooling component 7 has two working modes. In the first working mode, the cooling three-way valve 771 controls the input pipe communicated with the outside to communicate with the output pipe. After the air pump 71 operates, it extracts external air and transports it into the cooling shell 72, and sprays out air flow from the nozzle 721 onto the diesel engine 2 and the generator 3 to dissipate heat and cool down the diesel engine 2 and the generator 3. In the second working mode, the cooling three-way valve 771 controls the input pipe communicated with the synchronous three-way pipe 73 to communicate with the output pipe. After the air pump 71 operates, it extracts the gas in the oxygenation shell 51, so that a negative pressure is formed in the oxygenation shell 51, which is beneficial to promoting the regeneration of the oxygen-making molecular sieve in the oxygenation shell 51 and releasing the adsorbed nitrogen. The nitrogen is transported through the air pump 71. After the air pump 71 extracts the gas, it is also transported into the cooling shell 72, and the gas sprayed out from the nozzle 721 cools down the diesel engine 2 and the generator 3.

[0102] For the above two working modes, except for collecting different gases at the input end, high-speed gas can be sprayed out through the nozzle 721 to dissipate heat and cool down the diesel engine 2 and the generator 3, so as to extend the service life of the diesel engine 2 and the generator 3.

[0103] More specifically, in the above-mentioned cooling component 7, the cooling shell 72 and the air pump 71 are both fixed below the top plate 12. The cooling shell 72 is adjacent to the upper side of the diesel engine 2 and the generator 3. The nozzle 721 is located on the bottom surface of the cooling shell 72. The cooling shell 72 is stepped in the vertical direction, and its bottom surface size is larger than the top surface size to expand the blowing area and facilitate the fixed connection with the top plate 12 at the top. The top of the cooling shell 72 is open, and the cooling shell 72 and the top plate 12 enclose a cooling chamber. The output end of the air pump 71 is communicated with the nozzle 721 through the cooling chamber, which is convenient for the air pump 71 to deliver the introduced gas into the cooling chamber and then spray the gas from the nozzle 721 to cool the diesel engine 2 and the generator 3 below.

[0104] The synchronous three-way pipe 73 includes a synchronous shell 74. The synchronous shell 74 is cylindrical and is coaxially fixed above the corresponding switching shell 611 of the exhaust gas exhaust three-way pipe 6104. The synchronous shell 74 is fixedly communicated with a suction pipe and two suction pipes. The two suction pipes are coaxial and perpendicular to the axis of the suction pipe. The suction pipe is connected to the cooling three-way pipe 77. A synchronous valve 75 that is rotationally and sealingly fitted to the circumferential inner walls of its upper and lower inner walls is rotated in the synchronous shell 74. An L-shaped synchronous channel 76 is provided on the synchronous valve 75. The two ends of the synchronous channel 76 extend to the outer circumference of the synchronous valve 75. The synchronous valve 75 is coaxially fixedly connected to the corresponding switching valve 612 of the exhaust gas exhaust three-way pipe 6104, and the orientations of the two ends of the synchronous channel 76 on the synchronous valve 75 are the same as the orientations of the two ends of the switching channel 613 of the above-mentioned switching valve 612. Two docking covers 562 are fixedly communicated with both suction pipes. The two docking covers 562 correspond to the two oxygen-enriching units 5 one by one, and the docking covers 562 are fixedly communicated to the outside of the inlet and outlet barrel 561 on one side of the loop barrel 56.

[0105] After adopting the above structure, since the corresponding switching valve 612 of the exhaust gas exhaust three-way pipe 6104 is coaxially fixedly connected to the synchronous valve 75, the rotating unit 62 can drive the two to rotate synchronously, and the orientations of the two ends of the switching channel 613 on the switching valve 612 are the same as the orientations of the two ends of the synchronous channel 76 on the synchronous valve 75. Therefore, the oxygen-enriching shell 51 corresponding to the air pump 71 and the oxygen-enriching shell 51 through which the high-temperature exhaust gas discharged from the exhaust gas outlet 22 passes are the same oxygen-enriching shell 51. When regenerating the oxygen-making molecular sieve in the oxygen-enriching shell 51, the gas in the oxygen-enriching shell 51 can be extracted through the air pump 71, so that the oxygen-making molecular sieve can release nitrogen, and then pass through the inlet and outlet barrel 561, the docking cover 562, one of the suction pipes of the synchronous three-way pipe 73, the suction pipe of the synchronous three-way pipe 73, and then through one of the input pipes of the cooling three-way pipe 77, and is discharged from the output pipe, passes through the air pump 71, and then is sprayed out from the nozzle 721 of the cooling shell 72 to cool the diesel engine 2 and the generator 3. Then, the high-temperature exhaust gas generated by the operation of the diesel engine 2 passes through the heat exchange tube 514 in the same oxygen-enriching shell 51 to heat the oxygen-making molecular sieve in the oxygen-enriching shell 51 to promote the regeneration of the oxygen-making molecular sieve.

[0106] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
