Description

Technical Field

[0001] This invention belongs to the field of generator technology, specifically an energy-saving generator set cylinder temperature difference power generation waste heat recovery device. Background Technology

[0002] Energy-saving generators achieve efficient fuel conversion and energy recovery through technological innovation, mainly through three technical routes: fuel optimization, structural innovation, and energy reuse. Their core advantages lie in significantly reducing operating costs and carbon emissions. The ECU monitors load changes in real time and dynamically adjusts the fuel injection quantity and timing. When the load suddenly increases by 50%, fuel supply optimization can be completed within 0.3 seconds, avoiding fuel waste during transitional operating conditions. Low-temperature waste heat (≥90℃) is recovered to drive organic working fluid power generation. Magnetic levitation bearing technology eliminates the risk of lubrication leakage and reduces volume.

[0003] In industrial production, construction, emergency power supply and other fields, diesel generator sets serve as important backup power equipment. Their fuel economy directly affects the user's operating costs. The fuel-saving performance of modern diesel generator sets mainly relies on three major technological innovations. First, the application of electronically controlled high-pressure common rail fuel systems, such as the new third-generation electronic control systems adopted by brands like Yuchai and Shangchai, can achieve injection pressures of over 2000 Bar. Combined with multi-stage injection technology, this results in more complete fuel atomization and an improvement in combustion efficiency of over 15%. According to actual test data from a certain brand, a 30kW unit equipped with this system can achieve fuel consumption as low as 206g / kWh at 75% load, saving 8%-12% of fuel compared to traditional mechanical pump models. Second, the upgrade of intelligent speed control systems. Units using electronic speed governors and ECUs can adjust the fuel injection quantity in real time according to load changes, avoiding the "overpowered engine for underpowered vehicle" phenomenon of traditional mechanical speed control. For example, the Volvo PENTA control system can maintain ±1% speed stability within a load range of 30%-100%, saving 5%-7% of fuel consumption compared to mechanical speed control.

[0004] Even energy-saving generators in the current technology still generate a lot of heat during operation. Excessive temperature can damage the motor and its internal structure, affect the motor's service life, and may cause workers to come into contact with the outer wall of the generator cylinder due to improper operation. The heat transferred by the cylinder may directly burn the workers, causing personal injury accidents and hindering the workers' work process. Therefore, it is necessary to heat treat the outer wall of the generator cylinder. Summary of the Invention

[0005] To address the issues raised in the background section regarding the fact that even energy-efficient generators still generate significant heat during operation, excessively high temperatures can damage the motor and its internal structure, affecting its lifespan. Furthermore, improper operation by operators could result in burns from heat transfer to the generator's cylinder body, hindering the operator's work process.

The impeller is specifically made of stainless steel.

[0009] Preferably, an L-shaped pipe is movably sleeved on the shaft of the rotating shaft, and an inverted bucket-shaped water tank is fixedly connected to the top end of the L-shaped pipe. A water baffle is slidably connected through one end plate of the inverted bucket-shaped water tank near the bottom. A water cover is tightly snapped into the inner wall of the top end of the inverted bucket-shaped water tank, and an L-shaped connecting plate is fixedly connected between the outer wall of one end of the inverted bucket-shaped water tank and the outer wall of the top end of the motor.

[0010] Preferably, a cam is also fixedly connected to the shaft of the motor, and the cam can intermittently slide and engage with an arc-angle T-rod. Two partition discs are fixedly connected to the body of the arc-angle T-rod, and an irregularly shaped sleeve rod is fixedly connected to the body of the arc-angle T-rod.

[0011] Preferably, a pressure plate is fixedly connected to the other end of the irregularly shaped sleeve rod, and a conical material plate is slidably connected to the pressure plate. Two material trays are provided in the inner wall of the conical material plate. The two material trays are fixedly connected to the inner wall of the conical material plate and rotatably connected to it, respectively. A feeding hole is opened through one side of each of the two material trays. A section of the irregularly shaped sleeve rod is threadedly connected to the two material trays and slidably connected to them, respectively.

[0012] Preferably, a sleeve is movably sleeved on the rotating shaft, and the sleeve is fixedly connected to the bottom end of the conical material plate. A feed groove matching the bottom end of the conical material plate is opened through the outer wall of one end of the rotating shaft, and multiple discharge holes are opened around one side of the rotating shaft.

[0013] Preferably, a rubber disc is fixedly connected to the bottom end of the arc-angle T-bar, a piston cylinder is slidably connected to the rubber disc, a spring is fixedly connected between the bottom inner wall of the piston cylinder and the bottom outer wall of the rubber disc, and a ring rod bracket is fixedly connected to the outer wall of the piston cylinder near the bottom.

[0014] Preferably, a T-shaped plug is through-engaged on the bottom plate of the piston cylinder, and a spring is fixedly connected between the outer wall of the T-shaped plug and the inner wall of the bottom of the piston cylinder. A mesh sleeve is fitted between the piston cylinder and the ring rod frame.

[0015] Preferably, an inclined air pipe is fixedly connected through one end of the piston cylinder near the bottom, and a one-way valve is fixedly connected to the inclined air pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention involves a shaped sleeve that continuously moves downwards, sequentially contacting two material trays. This causes one of the trays to rotate. When the discharge hole of the passively rotating tray aligns with the discharge hole of the stationary tray, a small amount of nitrate powder placed inside the conical material plate is passively and pressurized and fed into the rotating shaft. The powder then flows through the discharge hole on the rotating shaft into an L-shaped pipe to mix with water. This mixture then flows through a connecting pipe into a surrounding water pipe, where it circulates. The dissolution of the nitrate powder absorbs heat, the cooling water temperature drops sharply, and the cylinder is cooled (to prevent overheating damage). This triggers a cam to control the nitrate feeding and piston pressurization, all without additional energy consumption.

[0019] This invention generates steam by heating water. The steam rises naturally and passes through two inclined plates installed inside the top of the water pipe. The cross-installation of the inclined plates allows the steam to come into contact with the polymer surface in a deflection manner. This maintains the temperature generated by the water when it is heated, and the residual heat of the generator cylinder is collected in another way. Finally, the rising steam is fully absorbed by the water through a sponge pad, leaving only gas to enter the gas box. The gas can then be guided into the gas converter through the gas guide pipe. The gas converter can be connected to other equipment to transfer and reuse the recovered waste heat. The cooling water absorbs heat and vaporizes, the steam is deflected and stored by the inclined plates, and the dried gas is guided to the gas converter for secondary use (such as driving a turbine). The sponge pad absorbs liquid water in the steam to ensure the dryness of the gas. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides an energy-saving generator set cylinder body temperature difference power generation waste heat recovery device, including generator body 1, a base plate 101 fixedly connected to the bottom end of generator body 1, a control box 102 fixedly connected to the top side wall of base plate 101, and a waste heat recovery section 2 jointly provided between base plate 101 and generator body 1.

[0033] The waste heat recovery unit 2 includes a surrounding water pipe 221 that guides cooling water. Two inclined plates 222 are fixedly connected in a cross pattern to a section of the vertical pipe surrounding the water pipe 221. The outer walls of the two inclined plates 222 are coated with a polymer coating. An air box 224 is fixedly connected through the top of the vertical pipe surrounding the water pipe 221. A sponge pad 223 is connected through the inner wall of the top of the vertical pipe surrounding the water pipe 221 and the inner wall of the bottom of the air box 224 to absorb a small amount of water in the water vapor. An air cover 225 is tightly connected to the inner wall of the top of the air box 224. A gas guide pipe 226 is fixedly connected through the side wall of one end of the air box 224. A gas converter 227 is fixedly connected to the other end of the gas guide pipe 226. The outer wall of the bottom end of the gas converter 227 is fixedly connected to the outer wall of the generator body 1.

[0034] The above scheme is adopted as follows: the cooling liquid medium that indirectly contacts the generator body 1 will generate water vapor in the surrounding water pipe 221 due to the temperature of the generator body 1 cylinder. The water vapor will naturally rise and pass through two inclined plates 222 installed in the top of the surrounding water pipe 221. The cross-installation of the inclined plates 222 allows the water vapor to come into contact with its polymer surface in a deflection manner. This can maintain the temperature generated by the water when it is heated and collect the residual heat of the generator body 1 cylinder in another way. Finally, the continuously rising water vapor will be fully absorbed by the water through the sponge pad 223, leaving only gas to enter the gas box 224. Then, the gas can be introduced into the gas converter 227 through the gas guide pipe 226. The gas converter 227 can be connected to other equipment to transfer and reuse the recovered waste heat.

[0035] The waste heat recovery unit 2 also includes a motor 201 fixedly connected to the outer wall of one side of the top of the base plate 101. A rotating shaft 202 for extending the shaft is fixedly connected to the shaft of the motor 201. An impeller 203 is threadedly connected to the shaft of the rotating shaft 202. The impeller 203 is made of stainless steel. An L-shaped pipe 204 is movably sleeved on the shaft of the rotating shaft 202. An inverted bucket-shaped water tank 205 is fixedly connected to the top of the L-shaped pipe 204. A water baffle 206 is slidably connected to the plate of the inverted bucket-shaped water tank 205 near the bottom. A water cover 207 is tightly snapped into the inner wall of the top of the inverted bucket-shaped water tank 205. An L-shaped connecting plate 208 is fixedly connected between the outer wall of one end of the inverted bucket-shaped water tank 205 and the outer wall of the top of the motor 201.

[0036] A cam 209 is fixedly connected to the shaft of the motor 201. The cam 209 can intermittently slide against an arc-angle T-rod 210. Two separator discs 2101 are fixedly connected to the body of the arc-angle T-rod 210. A shaped sleeve rod 2102 is fixedly connected to the body of the arc-angle T-rod 210. A pressure plate 2103 is fixedly connected to the other end of the shaped sleeve rod 2102. A conical material plate 2104 is slidably connected to the pressure plate 2103. Two material trays 2105 are provided in the inner wall of the conical material plate 2104. The two material trays 2105 are respectively fixed to the inner wall of the conical material plate 2104. The two material trays 2105 are connected by fixed and rotating connections, and each tray has a through-hole 2106 on one side. A section of the shaped sleeve 2102 is threaded and slidably connected to the two material trays 2105 respectively. A sleeve 2107 is movably sleeved on the rotating shaft 202. The sleeve 2107 is fixedly connected to the bottom end of the conical material plate 2104. A feed groove 2108 matching the bottom end of the conical material plate 2104 is through-hole opened on the outer wall of one end of the rotating shaft 202. Multiple discharge holes 2109 are through-hole opened around one side of the rotating shaft 202.

[0037] Using the above scheme: half of the water baffle 206 on the inverted bucket-shaped water tank 205 is removed, allowing the water in the inverted bucket-shaped water tank 205 to flow naturally downwards. The water then flows into the L-shaped pipe 204. Simultaneously, when the rotating shaft 202 rotates, it also drives the cam 209 to rotate, thus intermittently pressing down the arc-angle T-rod 210. The passive downward movement of the arc-angle T-rod 210 also drives the irregular sleeve rod 2102 and the pressure plate 2103 downwards, causing the pressure plate 2103 to act as a piston within the conical material plate 2104, generating extrusion force. As the irregular sleeve rod 2102 continues to move downwards, it will sequentially contact the two material trays 2105, thereby driving one of the material trays... The disc 2105 rotates. When the discharge hole 2106 of the passively rotating disc 2105 aligns with the discharge hole 2106 of the stationary disc 2105, a small amount of nitrate powder placed in the conical plate 2104 is passively and pressurized and fed into the rotating shaft 202 through the discharge hole 2106. The powder then flows through the discharge hole 2109 on the rotating shaft 202 into the L-shaped pipe 204 to mix with the water. The nitrate powder effectively cools the water. Subsequently, the downward flow of the water can drive the impeller 203 to rotate on the rotating shaft 202, thereby covering multiple discharge holes 2109 and preventing continuous water intake.

[0038] A rubber disc 211 is fixedly connected to the bottom end of the arc-angle T-bar 210. A piston cylinder 212 is slidably connected to the rubber disc 211. A spring 213 is fixedly connected between the inner wall of the bottom end of the piston cylinder 212 and the outer wall of the bottom end of the rubber disc 211. A ring rod bracket 214 is fixedly connected to the outer wall of the piston cylinder 212 near the bottom. A T-shaped plug 215 is inserted through the bottom plate of the piston cylinder 212. A spring is fixedly connected between the outer wall of the T-shaped plug 215 and the inner wall of the bottom end of the piston cylinder 212. 216. A mesh sleeve 217 is fitted between the piston cylinder 212 and the ring rod frame 214. An inclined air pipe 218 is fixedly connected through one end of the piston cylinder 212 near the bottom. A one-way valve 219 is fixedly connected to the body of the inclined air pipe 218. A through pipe 220 is fixedly connected through the other end of the L-shaped pipe 204. The other end of the through pipe 220 is fixedly connected through the body of the pipe surrounding the water pipe 221. The top end of the inclined air pipe 218 is fixedly connected through the bottom end of the L-shaped pipe 204.

[0039] The above scheme is adopted: when the arc-angle T-bar 210 is passively moved downward, it simultaneously drives the rubber disc 211 to move downward and compress the spring 213 in the piston cylinder 212, causing it to deform. This also enables the rubber disc 211 to generate compressed gas in the piston cylinder 212. The gas, carrying the impact force, is then introduced into the L-shaped pipe 204 through the inclined air pipe 218, pushing the flow of the mixed cooling water. This allows the water to enter the surrounding water pipe 221 through the through pipe 220, where it flows in a circumferential manner, thereby achieving a cooling effect on the outer wall of the generator body cylinder 1 and preventing the generator from... The body 1 spontaneously overheats and causes damage. When the cam 209 is passively rotated, it passively and repeatedly squeezes the arc-angle T rod 210, causing a reciprocating suction and squeezing process inside the piston cylinder 212. The passive upward suction process will drive the T-shaped plug 215 upward, thereby causing the spring 216 to deform and move upward elastically, thus smoothly drawing in the gas for the next squeeze, avoiding the formation of a negative pressure state inside the piston cylinder 212. The drawn-in gas will be filtered by the plug screen cylinder 217 to prevent impurities from entering. The presence of the one-way valve 219 will ensure that the inclined air pipe 218 can only allow gas to flow in one direction.

[0040] One point that needs to be added is: with Figure 8 As shown, the section of the rod connecting the irregular sleeve 2102 and the pressure plate 2103 is specifically a threaded rod. Subsequently, the irregular sleeve 2102 can be continuously passively moved upward, causing the pressure plate 2103 to disengage from the conical material plate 2104, thereby replenishing the cooling medium. The nitrate powder must be fed before the water enters the L-shaped pipe 204. Then, with half of the water baffle 206 pulled out, the downward flow of the water can drive the impeller 203 to rotate in the opposite direction on the rotating shaft 202, generating opposing forces, thereby covering multiple discharge holes 2109 to prevent continuous water intake. Subsequently, the impeller 203 can be rotated and reset by opening the water cover 207 with the help of tools.

[0041] The working principle and usage process of this invention are as follows: The motor 201 drives the rotating shaft 202 to rotate, which in turn drives the impeller 203 to rotate. This allows half of the water baffle 206 on the inverted bucket-shaped water tank 205 to be pulled out, allowing the water in the tank to flow naturally downwards into the L-shaped pipe 204. Simultaneously, the rotation of the shaft 202 also drives the cam 209 to rotate, intermittently pressing down the arc-angle T-bar 210. The passive downward movement of the arc-angle T-bar 210 also drives the irregular sleeve 2102 and the pressure plate 2103 to move downwards, causing the pressure plate 2103 to press against the conical material plate 210. The piston inside 4 generates extrusion pressure. As the irregular sleeve rod 2102 continues to move downward, it will contact the two material trays 2105 in sequence, thereby driving one of the material trays 2105 to rotate. When the discharge hole 2106 of the passively rotating material tray 2105 is aligned with the discharge hole 2106 of the stationary material tray 2105, the saltpeter powder placed in the conical material plate 2104 will be passively pressed out through the discharge hole 2106 and a small amount will be added into the rotating shaft 202. Then, it will be discharged into the L-shaped pipe 204 through the discharge hole 2109 on the rotating shaft 202 to mix with the water. In this way, the saltpeter powder can effectively cool and lower the temperature of the water.

[0042] Furthermore, when the arc-angle T-bar 210 is passively moved downwards, it simultaneously drives the rubber disc 211 to move downwards, squeezing the spring 213 in the piston cylinder 212, causing it to deform. This also enables the rubber disc 211 to generate compressed gas in the piston cylinder 212. The gas, carrying the impact force, is then introduced into the L-shaped pipe 204 through the inclined air pipe 218, pushing the flow of the mixed cooling water. This allows the water to enter the surrounding water pipe 221 through the through pipe 220, where it flows in a circumferential manner, thereby achieving a cooling effect on the outer wall of the generator body 1 cylinder and preventing the generator body 1 from becoming cold. The spontaneous overheating causes damage. When the cam 209 is passively rotated, it passively and repeatedly squeezes the arc-angle T rod 210, causing a reciprocating suction and squeezing process inside the piston cylinder 212. The passive upward suction process will drive the T-shaped plug 215 upward, thereby causing the spring 216 to deform and move upward elastically, thus smoothly drawing in the gas for the next squeeze, avoiding the formation of a negative pressure state inside the piston cylinder 212. The drawn-in gas will be filtered by the plug screen cylinder 217 to prevent impurities from entering. The presence of the one-way valve 219 will ensure that the inclined gas pipe 218 can only allow the gas to flow in one direction.

[0043] The cooling liquid medium, indirectly in contact with the generator body 1, generates water vapor in the surrounding water pipe 221 due to the temperature of the generator body 1 cylinder. This water vapor naturally rises and passes through two inclined plates 222 installed inside the top of the surrounding water pipe 221. The crisscrossing installation of the inclined plates 222 allows the water vapor to come into contact with the polymer surface (specifically, a waterproof coating made of polymer material) in a deflection manner. Upon contact with the water vapor, a moisture absorption reaction occurs, causing a slight increase in surface temperature. This maintains the initial temperature generated by the water when heated, collecting the residual heat of the generator body 1 cylinder in another way. Finally, the continuously rising water vapor passes through the sponge pad 223 for thorough water absorption, ensuring... The gas enters the gas box 224 and is then guided through the gas pipe 226 to the gas converter 227. The gas converter 227 can be connected to other equipment to transfer and reuse the recovered waste heat. After cooling the generator body 1 cylinder through the cooling liquid medium, the waste heat generated by the cylinder can also be recovered. This device significantly improves the waste heat utilization rate of the generator body 1 through the dual innovation of nitrate dissolution heat absorption enhanced cooling and water vapor waste heat cascade recovery. Its mechanical linkage design of cam 209, impeller 203 and material tray 2105 coupling realizes zero power consumption automated operation, has high industrial application value, reduces carbon emissions, improves resource reuse, and increases the flexibility and functionality of the device.
