[0033] Example 1
[0034] An embodiment of the present invention provides a gas engine intake air pretreatment device, comprising a gas processing box 1, wherein an air inlet 2 is provided at one end of the gas processing box 1, an air outlet at the other end of the gas processing box 1 is connected to an air heat exchanger 3, the air outlet of the air heat exchanger 3 is connected to the gas engine intake port, and a gas filter component and a gas dehumidification component are provided inside the gas processing box 1.
[0035] The beneficial effects of the above technical solution are:
[0036] By filtering, dehumidifying and cooling the intake air of the gas turbine, the combustion requirements of the gas entering the gas turbine are optimized and the combustion efficiency of the gas turbine for the gas is improved. Lowering the intake air temperature through a water-cooled intercooler can increase the air density, thereby increasing the air mass flow entering the gas turbine, improving the combustion efficiency, and then generating more power and improving the overall efficiency of the gas turbine.
[0037] Through multiple filtrations, particulate matter in the gas is largely removed, reducing wear on the engine. Gas pretreatment reduces the moisture content of the gas, preventing water droplets generated during the combustion process from adhering to the inside of the engine and causing corrosion to the engine.
[0038] Example 2
[0039] On the basis of Example 1, a gas processing chamber 4 is provided inside the gas processing box 1, and the air inlet 2 is provided on the left side wall of the gas processing box 1. The gas filter assembly includes a first filter cartridge 5, a second filter cartridge 6 and a filter plate 7. The filter plate 7 is fixedly connected to the inner wall of the gas processing chamber 4. The filter plate 7 divides the gas processing chamber 4 into a filter chamber 8 and a dehumidification chamber 9. The first filter cartridge 5 and the second filter cartridge 6 have the same structure, including a filter screen 10 and a mounting plate 11. The first filter cartridge 5 and the second filter cartridge 6 are both installed on the left inner wall of the filter chamber 8 through the mounting assembly. The first filter cartridge 5 is mounted on the outside of the air inlet 2, and the second filter cartridge 6 is mounted on the outside of the first filter cartridge 5.
[0040] Preferably, each group of mounting components includes a plurality of mounting columns 12 arranged along the left-right direction, the mounting columns 12 are fixedly connected to the left side wall of the filter chamber 8, the mounting plates 11 of the first filter cartridge 5 and the second filter cartridge 6 are slidably connected to the mounting columns 12 along the left-right direction, the right end of the mounting column 12 is fixedly connected to the limiting plate 13, and a spring 14 is fixedly connected between the limiting plate 13 and the mounting plate 11.
[0041] The beneficial effects of the above technical solution are:
[0042] By providing triple filtration of the first filter cartridge 5, the second filter cartridge 6 and the filter plate 7, the degree of filtering of particulate matter and other impurities in the gas is improved, and the content of particulate matter entering the combustion engine is reduced.
[0043] Different filter particle sizes are set by the first filter cartridge 5, the second filter cartridge 6 and the filter plate 7, so that impurities of different particle sizes stay on different filter levels, and the filter pressure is evenly distributed on different filter levels, avoiding excessive filter pressure at certain filter levels, resulting in a high probability of blockage and shortened service life.
[0044] When the first filter cartridge 5 and the second filter cartridge 6 are not blocked, the mounting plate 11 is in close contact with the inner wall of the filter chamber 8 under the action of the spring 14, ensuring that the incoming air passes through multiple layers of filtration and ensuring the filtering effect on the incoming air. When the first filter cartridge 5 and the second filter cartridge 6 are blocked, the gas permeability will decrease, which will lead to an increase in the incoming air pressure. As the incoming air pressure increases, the spring 14 is compressed, thereby creating a gap between the mounting plate 11 of the first filter cartridge 5 or the second filter cartridge 6 and the inner wall of the filter chamber 8, allowing part of the incoming air to pass through the gap into the next filter level, releasing excessive pressure, thereby avoiding damage to the blocked filter cartridge under excessive pressure, and by ensuring that the blocked filter cartridge can still exert some filtering effect, excessive filtering pressure on the next filter level is avoided, causing damage to the next filter level.
[0045] Example 3
[0046] On the basis of Example 2, the gas dehumidification assembly includes a support frame 15, which is fixedly connected to the inner wall of the dehumidification chamber 9. A rotating seat 16 is fixedly installed on the support frame 15. A plurality of telescopic frames 17 are fixedly connected to the rotating end of the rotating seat 16. An electric telescopic rod 18 is fixedly connected to the inside of each telescopic frame 17. An adjusting frame 19 is fixedly connected to the output end of the electric telescopic rod 18. A storage chamber 20 is provided in the adjusting frame 19. The storage chamber 20 is filled with dehumidification material, and the storage chamber 20 is connected to the outside through a plurality of ventilation holes.
[0047] Preferably, the gas dehumidification component also includes a material processing component, which includes a drying rack 21, which is fixedly connected to the top surface of the dehumidification chamber 9, and thermal insulation curtains are arranged on the front and back sides of the drying rack 21. An electric heating wire 22 is arranged on the bottom surface of the drying rack 21, and an exhaust pump 23 is installed on the outer top surface of the gas treatment box 1, and the air inlet of the exhaust pump 23 is arranged above the drying rack 21.
[0048] In this embodiment, the air heat exchanger 3 is a prior art, such as a new type of air heat exchanger 3 disclosed in CN220708158U.
[0049] In this embodiment, the dehumidification material is a recyclable dehumidification material, and the dehumidification material can be reused after being heated to evaporate the moisture inside.
[0050] The beneficial effects of the above technical solution are:
[0051] After being filtered, the gas enters the dehumidification chamber 9, and the moisture in the gas is adsorbed by the dehumidification material, thereby achieving the effect of dehumidifying the gas.
[0052] The rotating seat 16 drives the telescopic frame 17 to rotate, thereby driving the storage chamber 20 to rotate, thereby disturbing the gas, improving the contact uniformity between the gas and the dehumidification material, thereby improving the dehumidification effect on the gas, and then through the telescopic effect of the electric telescopic rod 18, the distance between the adjustment frame 19 and the rotating seat 16 can be adjusted, thereby further improving the contact uniformity between the gas and the dehumidification material, and further improving the dehumidification effect.
[0053] When the dehumidification effect is not good (i.e. the relative humidity of the air after dehumidification is still higher than the preset dehumidification threshold), the electric telescopic rod 18 is extended to the longest state, and the rotation angle of the rotating seat 16 is controlled, so that the storage chamber 20 containing the dehumidification material stays in the drying rack 21 in turn, and the water in the dehumidification material is evaporated by the heating of the electric heating wire 22 in the drying rack 21, and the gas containing a large amount of water is extracted from the gas treatment box 1 through the vacuum pump 23 to avoid affecting the dehumidification effect of the gas inside the drying chamber. By setting a thermal insulation curtain, the heat generated during the drying of the dehumidification material is prevented from being dissipated into the drying chamber, which reduces the The heat inside the drying rack 21 is dissipated, thereby improving the drying effect and drying efficiency of the dehumidification material. On the other hand, it prevents the heat from being dissipated into the dehumidification chamber 9, causing the gas temperature inside the dehumidification chamber 9 to rise, resulting in a decrease in the stability of the gas temperature. By keeping the storage chambers 20 filled with dehumidification materials in the drying rack 21 in turn, the dehumidification materials in the remaining storage chambers 20 can still achieve the dehumidification effect, reducing the frequency of shutdown operations and ensuring the continuity of the gas supply to the gas turbine. By automatically drying the dehumidification material, the efficient and stable dehumidification effect of the intake air is guaranteed, and there is no need for workers to perform maintenance after shutdown, which reduces the complexity of maintenance.
[0054] Example 4
[0055] Based on Example 3, the gas dehumidification component further includes a process control system, and the process control system includes:
[0056] A first humidity sensor is arranged at the air inlet of the dehumidification chamber 9 and is used to detect the relative humidity of the air before dehumidification;
[0057] The second humidity sensor is arranged at the air outlet of the dehumidification chamber 9 and is used to detect the relative humidity of the air after dehumidification;
[0058] A dehumidification effect monitoring module is used to monitor the relative humidity of the air after dehumidification in real time. When the relative humidity of the air after dehumidification is higher than a preset first threshold, the dehumidification material is dried;
[0059] The material life monitoring module is used to monitor the remaining service life of the dehumidification material. When the remaining service life is insufficient, the dehumidification material is replaced.
[0060] Preferably, the material life monitoring module includes:
[0061] Life correction unit, when all dehumidification materials have been dried, re-evaluates the remaining service life of the dehumidification materials;
[0062]
[0063] Among them, t fis the remaining service life; ln is the logarithmic function with e as the base; H r is the actual relative humidity of the air before dehumidification; P0 is the unit pressure; T r is the actual temperature of the air before dehumidification; T0 is the unit temperature; R is the ideal gas constant; A z The maximum allowable absolute humidity of the air entering the combustion engine; H c is the actual relative humidity of the air after dehumidification; T c is the actual temperature of the air after dehumidification; t0 is the unit time; t s is the usage time of the dehumidification material; A1 is the actual absolute humidity of the air before dehumidification; A2 is the actual absolute humidity of the air after dehumidification; A C It is the absolute humidity change value of the dehumidification process under the optimal state of the dehumidification material;
[0064] The alarm unit will sound an alarm when the remaining service life of the dehumidification material is lower than a preset second threshold value, reminding the staff to replace the dehumidification material.
[0065] In this embodiment, the maximum allowable absolute humidity of the air entering the combustion engine is determined after experimental measurement.
[0066] In this embodiment, the optimal state of the dehumidification material refers to the initial state of the dehumidification material, that is, the state when the dehumidification capacity is the highest. The absolute humidity change value of the dehumidification process in the optimal state of the dehumidification material is the absolute humidity change value measured when the dehumidification material is in the optimal state.
[0067] The beneficial effects of the above technical solution are:
[0068] By monitoring the relative humidity of the air after dehumidification, when the relative humidity of the air after dehumidification exceeds the preset first threshold, it means that the intake humidity of the gas turbine is too high, and it can be inferred that the dehumidification material is close to saturation at this time. At this time, the dehumidification material is dried to restore the dehumidification material to a dry state, thereby realizing automatic drying of the dehumidification material, reducing the number of shutdown operations, and ensuring the continuity of the gas supply to the gas turbine. By automatically drying the dehumidification material, the efficient and stable dehumidification effect of the intake air is guaranteed, and workers do not need to perform maintenance after shutdown, which reduces the complexity of maintenance. By judging the hygroscopic state of the dehumidification material and drying the dehumidification material, it is ensured that the dehumidification effect can be dried in time when the dehumidification effect is poor, thereby ensuring the dehumidification effect of the air, and at the same time reducing the number of startups of the material handling components, thereby reducing the time that the material handling components affect the air state during use, and reducing energy consumption.
[0069] After each dehumidification material is dried, the remaining service life of the dehumidification material is re-evaluated to determine the current fatigue state of the dehumidification material, and then determine whether the dehumidification material needs to be replaced, so as to avoid a substantial increase in the drying frequency after the dehumidification material has aged, or the dehumidification material still cannot meet the current dehumidification requirements after drying, resulting in energy waste and possible sudden shutdown accidents. By pre-evaluating the remaining service life of the dehumidification material, the dehumidification material can be replaced in a planned manner to ensure the normal operation of the gas turbine, while ensuring the stability of the dehumidification effect and avoiding energy waste.
[0070] When calculating the remaining service life of the dehumidification material, the The average attenuation rate of the dehumidification capacity of the dehumidification material up to now is calculated, and then the maximum allowable absolute humidity of the air entering the gas turbine is determined based on the performance requirements of the intake air required by the gas turbine. The maximum allowable attenuation degree of the dehumidification capacity of the dehumidification material is determined based on the air humidity of the gas source and the maximum allowable absolute humidity. Based on the current capacity attenuation degree of the dehumidification material and the average attenuation rate of the dehumidification capacity, the remaining time to reach the maximum allowable attenuation degree of the dehumidification capacity of the dehumidification material is calculated, thereby obtaining the remaining service life of the dehumidification material, and predicting the remaining service life of the dehumidification material based on the actual use of the dehumidification material, thereby improving the accuracy of the prediction results.
[0071] Example 5
[0072] The embodiment of the present invention further provides a method for pre-processing intake air of a combustion engine, which is applied to a device for pre-processing intake air of a combustion engine as described in any one of embodiments 1 to 4, comprising:
[0073] Step 1: Extract air from the external environment at a preset flow rate;
[0074] Step 2: Perform multi-layer filtration on the extracted air to remove particulate matter in the air;
[0075] Step 3: Dehumidify the filtered air to reduce the humidity of the air;
[0076] Step 4: Adjust the temperature of the dehumidified air to maintain the stability of the turbine intake temperature.
[0077] The beneficial effects of the above technical solution are:
[0078] By removing impurities such as moisture, dust, particulate matter, sulfide, carbon dioxide, etc. from the intake air, the gas is made purer, which is conducive to the full combustion of the fuel. Removing impurities from the intake air prevents the impurities in the intake air from being deposited in the engine during the combustion process, reducing the probability of engine blockage, while reducing the generation of corrosive products during the combustion process, reducing the damage to the engine. Through pretreatment methods such as filtering and temperature adjustment, the quality of air entering the engine can be optimized and the intake efficiency can be improved. The improvement of intake efficiency helps the engine to operate stably in a wider range of operating conditions and improve the overall performance of the engine.
