Description

Marine diesel engine exhaust gas heating hot water device

technical field

The utility model provides a ship diesel engine waste gas heating hot water device, which belongs to the field of engineering thermodynamics.

Background technique

For a long time, the hot water used on ships mainly uses electric heaters and solar water heaters to heat hot water. Since the electricity on ships comes from the electric energy generated by diesel generators on ships, the use of electric heaters will increase fuel consumption. Solar water heaters are used It is greatly affected by weather conditions and cannot meet the normal use requirements. For example, the utility model patent announced in the Chinese Patent Gazette on May 31, 2006: marine solar water heater, patent number: ZL200420080883.3, which consists of a water storage tank, a vacuum heat collecting tube, and a heat collector composed of a heat collecting tube tray. It is connected with the water storage tank through three sets of circulating water pipes. The collector is also equipped with a heat exchange water tank and an internal circulation water tank. The internal circulation water tank is set in the heat exchange water tank. The circulating water pipe is connected to the water storage tank, the water storage tank and the heat exchange water tank are respectively provided with sewage outlets, and the water storage tank is provided with a circulating water nozzle, a hot water outlet and a cold water outlet. The use of the solar water heater is greatly affected by weather conditions, and its performance needs to be further improved.

Contents of the invention

The purpose of this utility model is to provide a kind of water that can overcome the above-mentioned defects, use the waste heat of the waste gas discharged from the marine diesel engine to heat the water in the circulation pipeline, utilize the heat energy of the exhaust gas of the diesel engine to the greatest extent, do not consume extra fuel, and do not need to occupy the extra space of the ship. Use a safe and reliable marine diesel engine exhaust gas heating hot water device, the technical content of which is:

The marine diesel engine exhaust gas heating hot water device consisting of a water circulation system, an exhaust gas exhaust system and a marine diesel engine is characterized in that: the waste heat of the exhaust gas discharged from the marine diesel engine is used to heat the water in the circulation pipeline to provide hot water for the daily life of the personnel on the ship ;

The water circulation system consists of a water tank, a cold water pipe, a water pump, and a heating pipe. The water tank is fixedly installed on the ship and connected to the water inlet of the cold water pipe. The water outlet of the cold water pipe is connected to the water inlet of the water pump. The water outlet of the water pump is connected to the heating pipe. The water inlet end is connected, the heating pipe is wound on the muffler of the marine diesel engine, and the water outlet end of the heating pipe is connected to the water tank;

The exhaust gas exhaust system is composed of exhaust gas outlet pipe, muffler and exhaust gas exhaust pipe. One end of the exhaust gas outlet pipe is connected to the exhaust branch pipe of the marine diesel engine installed on the ship, and the other end of the exhaust gas outlet pipe is connected to one end of the muffler. The other end is connected with the exhaust gas exhaust pipe.

Working principle: When the ship diesel engine exhaust gas heating hot water device is required to supply hot water, turn on the control switch of the water pump to extract the water in the water tank, the water flows into the heating pipe through the cold water pipe, the water flowing through the heating pipe is heated by the muffler, and then passes through the The water outlet end of the heating pipe flows into the water tank to form circulating hot water.
