Internal combustion engine intercooler circulating water waste heat recovering device and method

Abstract

The invention discloses an internal combustion engine intercooler circulating water waste heat recovering device and method and relates to the field of internal combustion engine waste heat recovering. The internal combustion engine intercooler circulating water waste heat recovering device comprises a cooling tower system and a high-temperature water source heat pump system which are connected with an internal combustion engine intercooler. The cooling tower system and the high-temperature water source heat pump system run in parallel and are mutual standbys. The device is used for cooling internal combustion engine intercooler circulating water. At the normal situation, a high-temperature water source heat pump unit extracts heat energy from the internal combustion engine intercooler circulating water, and after internal circulation of the heat pump unit, hot water with the relatively high temperature is prepared and supplies heat to a user. When the heat pump unit breaks down or theuser does not have a demand for more heat, the heat pump unit stops running, at this time, the cooling tower system works and carries out cooling and heat dissipating on the circulating water in theinternal combustion engine intercooler. According to the internal combustion engine intercooler circulating water waste heat recovering device and method, the high-temperature water source heat pump and the distributed energy resource of the internal combustion engine as a prime motor are integrated, the utilization efficiency of the distributed energy resource can be remarkably improved, the energy resource is saved, the project cost is saved, and the safe reliability of system heat dissipation is improved.

Description

Technical field [0001] The invention relates to the field of waste heat recovery of internal combustion engines, in particular to a device and method for recovering circulating water waste heat of an internal combustion engine intercooler. Background technique [0002] As energy and environmental issues become increasingly prominent, how to improve energy efficiency and minimize environmental pollution in the process of energy consumption is an urgent problem to be solved. Natural gas distributed energy technology has received widespread attention due to its low pollution emissions and high energy efficiency. In recent years, the country and localities have continuously introduced policies to support the development of natural gas distributed energy. [0003] Natural gas distributed energy technology uses natural gas as fuel, and uses micro-gas turbines, gas turbines or gas internal combustion engines as prime movers to drive generator sets to generate electricity, and then the hi...

Problems solved by technology

But the shortcomings of the boiler system are also very obvious: the thermal efficiency of the boiler is low, and a gas supply system needs to be configured at the same time, and a dedicated gas boiler room must be set up. In order to prevent safety problems caused by gas leakage, the electrical equipment in the gas boiler room is made of explosion-proof products. Wait

In addition, the boiler is a pressure vessel, and the annual inspection of the boiler is required every year, which is very complicated both in operation management and system design
