Process for conducting secondary heat energy utilization on tail gas of stationery engine

Abstract

The invention discloses a process for conducting secondary heat energy utilization on tail gas of a stationery engine. A smoke inlet, a smoke chamber, a heat exchanger, an anechoic chamber and a smoke outlet which are sequentially connected are included. An air inflow pipe and a draught fan installed on the air inflow pipe are further included. The output end of the draught fan enters the heat exchanger, an opening is formed in the heat exchanger, and a hot air outflow pipe is installed on the opening. After the high-temperature tail gas of the engine is subjected to heat exchange, high-temperature hot air is used for conducting heating and heat preservation on drilling equipment and replaces a boiler. Compared with a water heating mode, the heating effect can be achieved, the draught fan is started for heat exchange and air supply only when the draught fan is needed, continuity and non-interruption of water heating are avoided, cost is far lower than that of water heating, and the purposes of reducing emissions and saving energy are achieved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a process for secondary heat energy utilization of stationary engine tail gas. Background technique [0002] At present, only 40.5% of the domestic 12V190 series diesel engine works is converted into effective mechanical power, and 59.5% of the heat exchanger (3) includes end panels connected with the smoke chamber (2) and the anechoic chamber (8) respectively (9), the two end panels (9) and the side walls form a closed chamber, and a plurality of heat exchange tubes ( 10) Solve the following technical problems: 1. The flue gas recovery device cannot form resistance to the exhaust of the diesel engine. 2. The influence of carbon deposits from diesel engine exhaust on the heat conduction of the exhaust gas recovery device. 3. Selection of recycling medium. In view of the above problems, the development of this technical field is restricted. However, the drilling team uses boilers to p...
