Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, in particular to a water-cooled muffler for a diesel generator set. Background Technique

[0002] A diesel generator set is a power generation device that uses diesel as the main fuel. It uses a diesel engine as the prime mover to drive a generator to generate electricity, which is a mechanical device that converts kinetic energy into electrical energy and heat energy. In order to reduce the noise generated by the generator set, mufflers are installed in all diesel engines of the generator set. In a silent generator set, the muffler is usually installed inside the silent box, so as to isolate the diesel engine from the outside world through the silent box body, aiming to reduce the noise of the diesel generator set.

[0003] The authorized announcement number is CN211008868U, which discloses a water-cooled muffler for a diesel generator set. This patented technology uses a box body with good sound insulation effect, and arranges the cooling chamber and the sound insulation chamber on the box body adjacent to each other, so that the high heat generated by the sound insulation cavity in the sound insulation chamber can be timely transferred to the cooling circulating water in the cooling chamber through a large-area heat dissipation partition. On the one hand, good cooling of the muffler is achieved through water-cooling circulation, and on the other hand, it is beneficial to realize the stable operation of the unit and good noise reduction effect. An insulating layer is provided on the inner wall of the sound insulation chamber, which is beneficial to further prevent the heat of the muffler from being dissipated into the silent box body, thereby effectively reducing the working temperature of the diesel generator set; however, in this scheme, when the muffler is subjected to noise reduction treatment, a box body with good sound insulation effect is used, but there are many types of box bodies with sound insulation effect, and not all of them are suitable for diesel generator sets. If used improperly, it will not only not reduce noise, but also cause damage to the diesel generator set. Moreover, the muffler of this diesel generator set does not have a smoke exhaust function and a flue gas treatment function, and the diesel generator set cannot make use of resources in a resource-saving manner. Therefore, a water-cooled muffler for a diesel generator set is needed to improve the above problems. Content of the Utility Model

[0025] Embodiment: Please refer to Figures 1-4 A water-cooled muffler for a diesel generator set as shown, including a body 1, with a control component 2 and a water-cooling component 3 fixedly connected inside the body 1;

[0026] In this embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 as shown, the body 1 includes a machine compartment 101, a side pipe compartment 104 fixedly connected to the side of the machine compartment 101, a loading pipe 105 fixedly connected to the top of the side pipe compartment 104, a muffler exhaust pipe 106 fixedly connected to the top of the loading pipe 105, a clean air filter 107 fixedly connected inside the muffler exhaust pipe 106, a sound insulation felt sleeve 108 fixedly connected inside the loading pipe 105, the control component 2 includes an electric fuel pump 201, a fuel filter 202 fixedly connected to the top of the electric fuel pump 201, a control board 203 fixedly connected inside the machine compartment 101, an electronic control unit 206 fixedly connected to the bottom of the control board 203. The water-cooling component 3 is arranged inside the sound insulation felt sleeve 108. The sound insulation felt sleeve 108 can improve the overall sound insulation effect of the equipment, prevent sound from spreading outside the equipment, avoid causing noise pollution, and protect the stable use of the water-cooling component 3. In addition to the sound insulation effect, the sound insulation felt sleeve 108 also has some other advantages. It has good sealing performance and can effectively block outdoor dust and pollutants from entering the water-cooling component 3.

[0027] Among them, the water-cooling component 3 includes a compressor 301. The water-cooling component 3 is arranged inside the sound insulation felt sleeve 108. A throttle position sensor 204, an intake air temperature sensor 205, and an oil pressure regulator 207 are fixedly connected to the top of the control board 203. A clamp 302 is fixedly connected to the side of the compressor 301, and a heat exchanger 303 is arranged inside the clamp 302. The bottom of the heat exchanger 303 is fixedly connected to the compressor 301. By using the clean air filter 107 and the fuel filter 202, the normal operation of the combustion system and the cleanliness of the fuel can be ensured, the exhaust gas emissions from the diesel generator exhaust pipe can be effectively reduced, the adverse impact on the environment can be reduced, and a more environmentally friendly power generation process can be realized. The throttle position sensor 204 and the intake air temperature sensor 205 can ensure the fuel injection effect and combustion quality.

[0028] In this embodiment, referring to Figure 1 and Figure 4As shown, a condensing pipe 304 is fixedly connected to the top of the clamp 302, a dual-pressure controller 305 is fixedly connected to the bottom of the condensing pipe 304, a thermostat 308 is fixedly connected to the top of the compressor 301, a liquid storage tank 306 is fixedly connected to the side of the condensing pipe 304, a liquid inlet pipe 307 is fixedly connected to the side of the liquid storage tank 306, a support base 309 is fixedly connected to the bottom of the compressor 301, there are three support bases 309, a sleeve base 103 is fixedly connected to the top of the machine compartment 101, a vibration isolation plate 102 is fixedly connected to the bottom of the machine compartment 101. The liquid storage tank 306 is used to store the high-pressure liquid from the condensing pipe 304, so as not to submerge the surface of the condensing pipe 304, which can give full play to the heat transfer area of the condensing pipe 304, and adjust and stabilize the refrigerant cycle to adapt to the change of working conditions. It also plays a role of liquid seal to prevent the high-pressure refrigerant gas from flowing into the low-pressure system pipeline.

[0029] In this solution, when a water-cooled muffler for a diesel generator set is in use, the electric fuel pump 201 uses diesel as fuel. Through the working principle of the internal combustion engine, the fuel is injected into the cylinder and self-ignites under the action of high-pressure air, generating an explosive force to push the piston, thereby driving the crankshaft to rotate and finally outputting power. During operation, the fuel filter 202 can increase the fuel utilization rate. The chilled water coming out of the liquid inlet pipe 307 enters the compressor 301 through the condensing pipe 304 and exchanges heat with the convective air in the machine compartment 101 and the side pipe compartment 104. During this process, the water temperature rises due to absorbing the heat of the air in the side pipe compartment 104, while the air in the machine compartment 101 cools down after passing through the heat exchanger 303, so as to achieve the purpose of continuous refrigeration.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
