Intelligent cooling device of waste heat of waste gas of diesel generating set and method

Abstract

The invention discloses an intelligent cooling device of waste heat of waste gas of a diesel generating set and a method. The intelligent cooling device comprises a controller, and a power system and a cooling system which are respectively connected with the controller, and further comprises a connecting pipeline, an exhaust pipeline, a condenser and a water collecting tank. One end of the power system is connected with the exhaust pipeline while the other end of the power system is connected with an input end of the condenser. The output end of the condenser is connected with the connecting pipeline. The cooling system comprises a radiating fan, and an expansion valve and an evaporator which are sequentially arranged on the connecting pipeline. According to the intelligent cooling device of waste heat of waste gas of the diesel generating set and the method provided by the invention, energy of waste gas in the exhaust pipeline of the generator is used to refrigerate, so that components in the generator are always at a temperature in the optimal work environment. The efficiency of the generator at the moment is the highest, and the available power of the generator is improved, so that the efficiency of the diesel generating set is further improved and the service life of the generator is further prolonged. The refrigerating gas in the evaporator extracts fresh water from air by means of latent heat of vaporization while cooling the inside of the generator.

Description

technical field [0001] The invention relates to a diesel generator set, in particular to an intelligent cooling device and method for exhaust gas waste heat of a diesel generator set. Background technique [0002] Diesel generator sets are widely used in all walks of life due to their light weight, simple structure, and high power density. Diesel generator sets generally consist of three parts, specifically: diesel engine, generator, and control system. The diesel engine is the core and provides the driving force. At present, the thermal efficiency of commercial diesel engines is up to 43%, and the exhaust gas and cooling water account for more than 41% of the total energy. Among them, the exhaust gas discharge energy accounts for the largest proportion, about 30% of the total energy. If the exhaust gas Energy recovery and utilization will greatly improve the thermal efficiency of diesel generator sets. In the diesel generator set, the temperature rise has the greatest impa...

AI Technical Summary

Problems solved by technology

Especially for low-noise diesel generator sets with mute boxes and diesel generator sets used in tropical areas or deserts, the above situation is particularly prominent. Because the generator windings do not work in the best environmental conditions for a long time, the actual life is greatly reduced, and the actual The power is often much smaller than the rated power, which reduces the power of the generator set
