Thermal pollution reduction device and method of internal combustion engine distribution type energy station

Abstract

The invention relates to a thermal pollution reduction device and method of an internal combustion engine distribution type energy station. The device is characterized in that smoke is charged into a smoke inlet of a high-temperature heat exchanger through a main smoke exhausting pipe, wherein a smoke outlet of the high-temperature heat exchanger is connected to a smoke inlet of a low-temperature heat exchanger; a smoke outlet of the low-temperature heat exchanger is connected to a low-temperature smoke output pipeline which is used for outputting low-temperature smoke subjected to heat exchanging; a second temperature sensor is mounted on a second pipeline; an induced draft fan is mounted at the tail end of the low-temperature smoke output pipeline, and a drying hearth device is mounted in the pipeline; a water inlet of the low-temperature heat exchanger is connected to an outer cooling water source, and a water outlet of the low-temperature heat exchanger is connected to a water inlet of the high-temperature heat exchanger; a first water conveying pipe is connected to a low-temperature domestic hot water conveying pipeline; and a water outlet of the high-temperature heat exchanger is connected to an outer heat supplying hot water pipeline and is used for outputting high-temperature hot water. With the adoption of the device and the method, the waste heat of smoke is utilized to the maximum, so that the primary energy utilization rate of the energy station is increased; and moreover, the emission of pollutant NOx in exhausted gas can be reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas pollution control, in particular to a device and method for reducing thermal pollution of a gas internal combustion engine distributed energy station. Background technique [0002] At present, the pressure on the environment is increasing day by day. The energy system that uses coal as the main fuel for centralized power generation is facing the current situation of compressed production capacity. The clean energy represented by natural gas has ushered in a spring of great development. The natural gas distributed power station has the characteristics of being close to users, small installed capacity, simultaneous supply of cold, heat and electricity, cascaded utilization of energy, fixed power by heat, fast and convenient start and stop, and is an energy supply method vigorously promoted by the country. . [0003] At present, the country has no clear requirements on the emission of energy statio...

AI Technical Summary

Problems solved by technology

Since the load change of the gas-fired internal combustion engine distributed energy station is not considered, there is no information exchange with the energy station, and the design working condition is adopted. During the use process, the efficiency of the heat exchanger drops sharply with the passage of time, the corrosion is serious, and the service life is short.
