Description
Technical Field
[0001] The invention relates to the technical field of diesel generators, and in particular to an energy-saving diesel generator. Background Art
[0002] As an important backup and mobile power supply equipment, diesel generator plays an irreplaceable role in many fields. It uses diesel as fuel and generates power through the combustion of diesel engine, which in turn drives the generator to generate electricity. During the combustion process, diesel and air are mixed and self-ignited, generating a large amount of heat energy, which drives the piston to move, and then drives the crankshaft to rotate through the connecting rod. When the crankshaft rotates, electrical energy is generated through the magnetic field and coil inside the generator, achieving the purpose of converting mechanical energy into electrical energy. However, as a non-renewable energy source, diesel prices are frequently falling and on an upward trend as global energy reserves gradually decrease, which undoubtedly increases the operating cost of diesel generators. Therefore, it is necessary to use an energy-saving diesel generator;
[0003] To this end, the patent with the authorization announcement number CN107435586BU discloses an energy-saving diesel generator set. The energy-saving diesel generator set belongs to the technical field of power generation equipment, and solves the problems of low air purity, poor dust removal effect, and poor preheating effect of diesel generator sets in the prior art. It includes a chassis, and a compartment is provided above the chassis. A water tank, a diesel engine, and a generator are sequentially provided in the compartment. An air filter device is provided on the diesel engine. The air filter device includes a drying and dust collection mechanism and a temperature pre-adjustment mechanism. The drying and dust collection mechanism includes an air duct with a molecular sieve baffle, an electrostatic generator, and an ash storage bin provided at the bottom of the electrostatic generator. A temperature pre-adjustment mechanism is provided on the other side of the drying and dust collection mechanism. The present invention purifies the gas entering the diesel engine by providing an air filter device, and prevents air with particulate dust from entering the diesel generator. The electrostatic generator is used to generate static electricity to adsorb dust and particles mixed in the air.
[0004] The energy-saving diesel generator set mentioned above is equipped with a temperature pre-adjustment mechanism. When the air temperature does not reach the intake temperature requirement of the diesel generator set, the heating pipe is started to heat the air so that the air temperature meets the intake requirement. However, the temperature pre-adjustment mechanism consumes additional electrical energy when in use, and a large amount of waste heat is generated during the operation of the diesel generator and is not recycled, resulting in poor energy saving performance when in use.
