Household bathing wastewater heat exchange device

Abstract

The invention provides a household bathing wastewater heat exchange device which comprises a heat exchange tank; the heat exchange tank is composed of an upper heat exchange chamber, a partition plate and a lower heat exchange chamber; the upper heat exchange chamber is arranged at the upper end of the partition plate; the lower heat exchange chamber is arranged at the lower end of the partition plate; a plurality of cylindrical water leakage pipes are arranged on the partition plate; a bathing wastewater inlet pipe is arranged at the left upper end of the upper heat exchange chamber; a filtered matter discharge pipe is arranged at the right upper end of the upper heat exchange chamber; a filter barrel is arranged at the upper end in the upper heat exchange chamber; a stainless steel metal filter screen is arranged at the middle part in the upper heat exchange chamber; a heat exchange water tank is arranged at the lower end in the upper heat exchange chamber; the left end of the filter barrel is connected with the bathing wastewater inlet pipe; the right end of the filter barrel is connected with the filtered matter discharge pipe; a serpentine curved heat exchange pipe is arranged in the lower heat exchange chamber; an orifice at the upper end of the serpentine curved heat exchange pipe penetrates through the partition plate and is connected with the right side of the bottom end of the heat exchange water tank; and the other end of the serpentine curved heat exchange pipe is connected with a heat exchange water outlet pipe at the left lower end of the heat exchange tank. The household bathing wastewater heat exchange device has the advantages of high recovery efficiency, large recovery heat and long service life.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a heat exchange device for domestic bathing wastewater. Background technique [0002] In the conventional bathing system, the bathing wastewater with a higher temperature after use is directly discharged into the sewage system, so that a large amount of heat contained in the sewage is directly discharged and wasted. The hot water for bathing in domestic water heaters is around 40°C. After spraying the human body, the temperature is still very high, about 35°C-37°C. The current situation is that these hot water with high temperature are directly discharged to the sewer. It is a great waste of energy. On the other hand, with the further rise of electricity and natural gas prices, residents' water consumption for bathing or gas consumption will further increase. Under normal circumstances, if this part of heat can be effectively recovered and recycled, it will be of great significance to s...

Problems solved by technology

[0002] In the conventional bathing system, the high-temperature bathing wastewater after use is directly discharged into the sewage system, so that a large amount of heat contained in the sewage is directly discharged and wasted.

The hot water for bathing in domestic water heaters is around 40°C. After spraying the human body, the temperature is still very high, about 35°C-37°C. The current situation is that these hot water with high temperature are directly discharged to the sewer. It is a great waste of energy. On the other hand, with the further rise of electricity and natural gas prices, residents' water consumption for bathing or gas consumption will further increase. Under normal circumstances, if this part of heat can be effectively recovered and recycled, it will be of great significance to save energy, save electricity bills, and protect the environment.
