AI Technical Summary

Technical Problem

Existing natural gas generator sets have reduced combustion efficiency in low-temperature environments, and the heat from exhaust gases is not effectively utilized, resulting in energy waste.

Method used

A preheating device is used to transfer the heat of the hot gas in the exhaust pipe to the cold air through the heat exchange pipe. Multiple rows of staggered heat exchange pipes are used to increase the contact area, and the stability of the preheating effect is ensured by adjusting and balancing components. Combined with a transition device, preliminary filtration and preheating are performed.

Benefits of technology

It increases the intake air temperature without the need for additional power, enabling the recycling of energy, ensuring stable combustion of natural gas and power generation efficiency, reducing operating costs, and avoiding resource waste.

Abstract

The invention discloses an energy-saving natural gas internal combustion generator set. The energy-saving natural gas internal combustion generator set is characterized by comprising a box shell, a generator set whole body, an exhaust device, a filtering device and a preheating device, an air inlet is formed in any side surface in the width direction of the box shell; the exhaust device comprises an exhaust pipeline; the exhaust pipeline upwards extends out of the top of the box shell; the preheating device is arranged on the side face of the box shell of the air inlet and communicated with the air inlet, the preheating device comprises a plurality of heat exchange pipelines, and gaps between the heat exchange pipelines are used for gas flowing, so that gas outside the box shell enters the box shell through the gaps; the preheating device further comprises an air inlet part and an air outlet part which communicate with the two ends of the heat exchange pipeline. The gas inlet part extends into the box shell and is communicated with the gas exhaust pipeline, and the gas outlet part is communicated with the gas exhaust pipeline located outside the box shell, so that hot gas in the gas exhaust pipeline is introduced into the gas channel and then discharged into the gas exhaust pipeline through the gas outlet part, cold gas circulating in the gap is heated, and the temperature of the gas entering the box shell is increased.
