Problems solved by technology

[0005] In order to overcome the disadvantages of the prior art that the direct removal of high-temperature exhaust gas causes a large amount of energy waste, affects the surrounding environment, and cannot directly express the amount of energy saved, the present invention provides a method that can recover waste heat in exhaust gas and convert high-temperature exhaust gas into normal temperature or low temperature. Exhaust gas is then discharged to save energy and be beneficial to environmental protection. The exhaust gas waste heat recovery system with metering device can visually indicate the amount of energy saved.

Embodiment Construction

[0030] With reference to accompanying drawing, further illustrate the present invention:

[0031] Exhaust gas waste heat recovery system with metering device, including a box body 1 and a heat pipe 2 arranged inside the box body 1. The heat pipe 2 is covered with a partition that separates the inner cavity of the box into an exhaust gas sub-chamber and a fresh air sub-chamber 3. The exhaust gas sub-chamber is provided with a high-temperature exhaust gas inlet 4 and a low-temperature exhaust gas outlet 5 formed after heat exchange, and the fresh air sub-chamber is provided with a low-temperature fresh air inlet 6 and high-temperature fresh air formed after heat exchange Outlet 7; the evaporation section 21 of the heat pipe 2 is located in the exhaust gas sub-chamber, and the condensation section 22 is located in the fresh air sub-chamber;

[0032] The low-temperature new air inlet 6 is provided with an inlet temperature sensor for obtaining the temperature before the new air en...

Abstract

The invention discloses a waste gas residual heat reclaiming system with a metering device. The system comprises a box body and a heat pipe, a partition plate for partitioning the cavity of the box body into a waste gas sub cavity and a fresh air sub cavity is sleeved on the heat pipe, the waste gas sub cavity is provided with a high-temperature waste gas inlet and a low-temperature waste gas outlet, and the fresh air sub cavity is provided with a low-temperature fresh air inlet and a high-temperature fresh air outlet; the evaporation section of the heat pipe is positioned in the waste gas sub cavity, and the condensation section of the heat pipe is positioned in the fresh air sub cavity; an inlet temperature sensor and a Pitot tube are arranged at the low-temperature fresh air inlet, and an outlet temperature sensor for acquiring the temperature of fresh air subjected to heat exchange is arranged at the high-temperature fresh air outlet; and both the fresh air temperature sensed by the inlet and outlet temperature sensors and the fresh air flow rate acquired by the Pitot tube are input to a processor, and the processor is connected with a display device. The system has the advantages of reclaiming the residual heat in the waste gas, converting the high-temperature waste gas into normal-temperature or low-temperature waste gas and then discharging the waste gas, saving energy, facilitating environment friendliness and intuitively expressing energy saving amount.

Description

technical field [0001] The invention relates to an exhaust gas waste heat recovery system with a metering device. technical background [0002] In the textile industry, the heat setting machine is one of the main energy-consuming machines, because the working principle of the heat setting machine is a machine that uses heated air to dry and organize textiles (such as cloth) to set them. In a general heat setting machine, the required hot air temperature is about 200 degrees, and the heat setting exhaust air is discharged by a fan. At this time, the discharged temperature generally reaches 160 degrees or even higher, which contains rich heat energy. [0003] It can be seen that if the exhaust gas containing a large amount of heat energy is not recycled, it will cause loss and waste of heat energy, which is not conducive to sustainable development. At the same time, it will increase the production cost of the company and will be at a disadvantage in market competition. The st...
