Description

Air compressor waste heat exchanger

technical field

The utility model relates to an air compressor waste heat utilization device, in particular to an air compressor waste heat exchanger with high conversion rate of the air compressor waste heat.

Background technique

Generally, each factory needs to provide some convenient living facilities for employees, such as hot water for showering. Existing solutions include coal-fired boilers, diesel furnaces, petroleum gas furnaces, solar energy, air energy heat pumps, etc., each of which has its own advantages. There are pros and cons, but without exception, coal, diesel, petroleum gas, electric energy and other energy sources are required to obtain comfortable hot water, and the purchase of these devices requires a high investment, and energy consumption will continue after the equipment is completed to work. Therefore, being able to use the existing conditions of the factory, such as: the waste heat of the air compressor, to obtain comfortable hot water without consuming other energy sources, has become the first choice for energy saving.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defects of the prior art, and provide an air compressor waste water heat exchanger which can save energy and skillfully utilize the existing conditions of the factory to solve the problem of hot water.

In order to achieve the above purpose, the technical solution provided by the utility model is as follows: construct an air compressor waste water heat exchanger, including an inner barrel, and an outer barrel tightly wrapped outside the inner barrel, and the airtight seal formed between the inner barrel and the outer barrel The cavity is tightly connected to the copper pipe at the inner end of the airtight cavity, the top of the inner barrel is provided with a water inlet, the lower part of the inner barrel and the airtight cavity is provided with a communication hole, and the upper part of the outer barrel is provided with a water outlet.

The upper end and the lower end of the copper pipe are closely connected with the upper oil distribution pipe and the lower oil distribution pipe respectively, and the oil distribution pipes are closely connected with several copper pipes, and the several copper pipes are interspersed and wound on the outside of the inner barrel; the upper and lower oil distribution pipes They are respectively connected in series to the hot oil outlet of the air compressor and the oil return inlet of the air compressor, so that the hot oil flows through the copper tube to transfer heat and is absorbed by the cold water flowing through the cavity to generate hot water. The water temperature is inversely proportional to the flow rate and the suction The heating time is directly proportional, and its flow and time are controlled by the electronic temperature controller, and the function of adjusting temperature is achieved.

The upper and lower ends of the inner barrel are respectively provided with upper and lower grooves, and the upper and lower oil distribution pipes are respectively tightly arranged in the upper and lower grooves; the communication hole is opened at the connection between the lower groove and the inner barrel.

The water inlet is closely connected with the cold water pipeline, and the water outlet is closely connected with the hot water pipeline.

The outer end of the outer barrel is covered with an insulating layer. In order to make the exchanger look beautiful, a box body can also be set over the outer end of the outer barrel, and all components such as the outer barrel are fixed in the box, which is more convenient to use.

The working principle of the utility model is: using the high temperature hot oil of about 100 ℃ generated by the air compressor during work, the heat is transferred to the cold water through a number of copper tubes soaked in the flowing cold water in the circulating flow, so as to realize the cooling of the flowing cold water. Heating, and then the heat of the oil pipe is continuously taken away by the flow of water, which can not only reduce the temperature of the hot oil in the oil pipe by 20-40°C, but also heat the temperature of the cold water by 10-50°C, meeting the needs of factory employees for showering, etc., which is energy-saving and efficient. Environmental protection is worthy of vigorous promotion by factories. It can reduce the energy consumption of factories and has the effect of energy saving and environmental protection.

The benefit of the utility model is that it has less investment, saves energy, and can be installed and used by using the existing conditions of the factory. Without consuming new energy, the waste heat of the original air compressor is cleverly used to heat the cold water. It has excellent performance of energy saving and environmental protection.
