An energy-saving hot water supply system

Abstract

The invention discloses an energy-saving hot water supply system, which includes a thermal insulation water tank, the thermal insulation water tank is connected with a heat exchange system, a steam heating system, a hot water supply system and a water injection system, and the heat exchange system includes a first water inlet pipe, The first return pipe and heat exchange mechanism; the steam heating system includes a steam heat exchanger, a steam inlet pipe, a second water inlet pipe, a second water outlet pipe, and a condensed water outlet pipe; the hot water supply system includes a third water inlet pipe . Water equipment and a third return pipe; the water injection system includes a condensed water heat exchanger, an external water injection pipe, a condensed water drain pipe, a water injection pipe for a heat exchange system, and a water injection pipe for an insulated water tank. The invention has the advantage of comprehensive utilization of waste heat such as solar energy, flue gas from a silk dryer, flue gas from a combustion furnace, steam, etc., which ensures the supply of hot water whose temperature meets the usage requirements and reduces energy consumption.

Description

technical field [0001] The invention belongs to the technical field of industrial hot water supply, and in particular relates to an energy-saving hot water supply system. Background technique [0002] Since cigarette factories add flavors and fragrances to tobacco during tobacco processing, employees may be exposed to these during the production process. Cigarette factories have employee bathrooms, and employees have to take a bath after get off work. Some workshops also have cleaning rooms that require hot water. To clean the glue on the plastic box. The hot water needed in traditional bathhouses and cleaning rooms uses steam to exchange heat with tap water, and the steam heats the tap water into hot water to supply hot water for bathing and cleaning rooms. Solar energy technology is relatively mature now, and only relying on solar energy to supply hot water is greatly affected by weather changes. The production workshop has silk drying machines, combustion furnaces, boile...

AI Technical Summary

Problems solved by technology

Now solar technology is relatively mature, and the hot water supply by solar energy alone is greatly affected by weather changes

The production workshop has equipment such as silk drying machines, combustion furnaces, and boilers. After these equipment burn natural gas, the temperature of the flue gas in the chimney is relatively high, and it is directly discharged into the atmosphere, and the heat energy of the flue gas is wasted.
