Abstract
The invention discloses a waste heat recovery heat exchanger, which comprises a waste water pipe, a heat exchange cavity, a cold water port and a hot water port, wherein the waste water pipe is sleeved outside the heat exchange cavity, the cold water port is arranged below the heat exchange cavity, and the hot water port is arranged on the heat exchange cavity.
Description
Technical Field
The invention relates to the field of heat exchangers, in particular to a waste heat recovery heat exchanger.
Background
In the north of China, a large number of centralized bathrooms exist, the number of people for bathing is large, and the amount of hot water consumed each year is huge. The temperature of hot water supplied in a bathroom is about 45 ℃, the temperature of waste water discharged after bathing is about 30 ℃, the waste water has a large amount of waste heat, and the part of energy is wasted in vain.
In addition, in other production lives, a lot of phenomena with waste heat and waste water discharge also exist, and great waste of energy is caused. Along with the requirements of energy conservation and emission reduction on social construction and further reduction of energy consumption in production and life, a waste heat recovery device is needed, can recycle waste heat in waste water, and has a large recycling and utilizing space due to the waste heat of water for production and life, heating of buildings, even power generation and the like.
Disclosure of Invention
Aiming at the existing problems, the invention is researched and improved, and provides a waste heat recovery heat exchanger which has the advantages of compact structure, convenience in installation and wide application, effectively meets the installation mode of customers and the arrangement requirements of inlet and outlet pipelines, finally realizes the recovery and utilization of waste heat, and can effectively reduce the energy consumption in production and life.
The technical scheme adopted by the invention is as follows: the waste heat recovery heat exchanger comprises a waste water pipe, a heat exchange cavity, a cold water port and a hot water port, wherein the waste water pipe is sleeved with the heat exchange cavity, the cold water port is arranged below the heat exchange cavity, and the hot water port is arranged on the heat exchange cavity.
According to the waste heat recovery heat exchanger, waste water enters from the upper part of the waste water pipe, and heat is transferred to the heat exchange cavity on the other side of the pipe wall of the waste water pipe through the waste water pipe. Water in the heat exchange cavity enters from the cold water port, is heated in the heat exchange cavity and flows out from the hot water port.
The waste water pipe is made of aluminum materials, so that the heat conducting performance is good, and the heat recovery efficiency is high.
The waste heat recovery heat exchanger has the beneficial effects that the structure is simple, the maintenance is easy, the waste heat in the waste water can be recovered and utilized, and the waste heat recovery heat exchanger has a large recovery and utilization space due to the waste heat of the production and living water, the heating of buildings, even the power generation and the like.
Drawings

FIG. 2 is a sectional view
In the figure 1, a waste water pipe 1, a heat exchange cavity 2, a cold water port 3 and a hot water port 4 are arranged.
Detailed Description
The technical solution of the present invention is further explained with reference to the drawings, but the present invention is not limited thereto
The following embodiments are described.
As shown in figure 1, the invention relates to a waste heat recovery heat exchanger, which comprises a waste water pipe 1, a heat exchange cavity 2, a cold water port 3 and a hot water port 4, wherein the waste water pipe is sleeved outside the heat exchange cavity, the cold water port is arranged below the heat exchange cavity, and the hot water port is arranged on the heat exchange cavity. Waste water enters from the upper part of the waste water pipe 1, and heat is transferred to the heat exchange cavity 2 on the other side of the pipe wall of the waste water pipe through the waste water pipe. Water in the heat exchange cavity 2 enters from the cold water port 3, is heated in the heat exchange cavity 2 and flows out from the hot water port 4. Fig. 2 shows a sectional view of a waste heat recovery heat exchanger.
