An ion air heat exchanger for waste heat recovery of natural gas engine

Abstract

The invention provides an ionic wind heat exchanger for waste heat recovery of a natural gas engine. The ionic wind heat exchanger comprises a box body, an ionic wind generator module, and at least one heat exchange water pipe, wherein the ionic wind generator module is arranged in the box body, and comprises a plurality of line electrodes and a plurality of parallelly arranged horizontal plate electrode groups; each horizontal plate electrode group comprises a plurality of horizontal plate electrodes which are horizontally arranged at a certain interval from top to bottom; one line electrodeis arranged between the every two adjacent horizontal plate electrodes in the horizontal plate electrode groups; the line electrodes are emitting electrodes; the horizontal plate electrodes are receiving electrodes; and the heat exchange water pipes stretch into the box body from the top surface of the box body, are positioned between the every two adjacent horizontal plate electrode groups, bendand snake between the bottom surface and the top surface of the box body to penetrate through intervals between the every two adjacent horizontal plate electrode groups, and stretch out of the box body. According to the ionic wind heat exchanger, the structure is simple, the waste heat recovery rate is high, the structure is compact, power consumption is low, and harmful components in exhaust of the engine can be treated.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to an ion air heat exchanger used for recovery of waste heat from a natural gas engine. Background technique [0002] Natural gas comes from a wide range of sources and is an important renewable energy source. The composition of natural gas is 50-60% CH4, 40-50% CO 2 , water and other trace substances, it can be used as an important alternative fuel for engines. However, the effective power of the engine is generally only 20-40%, and most of the energy is wasted through the cooling medium or exhaust. For natural gas engines, the exhaust gas temperature is generally 300-400°C, so it can be seen that the recovery and utilization of residual heat energy has great potential for development. [0003] Heat exchanger is an important waste heat recovery tool, which is usually used for energy exchange between cold and hot media. Conventional heat exchangers have a residual he...

AI Technical Summary

Problems solved by technology

Conventional heat exchangers have a residual heat recovery rate of about 75-80%, which can greatly increase the output power of the engine. However, in order to ensure the heat exchange rate, the size of the device is generally large; The harmful ingredients cannot produce substantial changes
