Description

Waste heat recovery drying unit with air duct

technical field

The utility model relates to a drying unit, in particular to a waste heat recovery drying unit with an air duct.

Background technique

Dryers have been widely used in various fields such as industry, agriculture and life. Under the suction of the fan, the dryer turns the fresh cold air outside directly through the air inlet to heat exchange with the heating device and then turns it into dry hot air, and then exchanges heat with the items to be dried. Since the evaporation of moisture in the items needs to absorb and consume heat energy, the exhaust temperature of the dryer will gradually increase as the moisture in the items to be dried decreases. The problem existing in the existing dryer is that the exposed heat dissipation of the heating device and the heat dissipation of the casing are wasteful, and the fluctuation of the steam pressure has a great influence on the energy consumption.

Therefore, it is necessary to provide a new technical solution to solve the above problems.

detailed description

In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with the embodiments and accompanying drawings. The embodiment is only used to explain the utility model, and does not constitute a limitation to the protection scope of the utility model.

As shown in Figure 1, the waste heat recovery drying unit with air duct of the present utility model includes a box body 1, and a middle partition 13 is arranged in the box body 1, and the middle partition 13 divides the box body 1 into two parts. One part is the heating side, and the other part is the exhaust side. The exhaust side is provided with exhaust inlet 5, fan 12, primary filter 18, exhaust outlet 4 and exhaust pipe 16 in sequence, and the heating side is provided with fresh air inlet in sequence. 3. Primary filter 18, fan 12, heating device 10, humidifying device 11, fresh air outlet 2 and air supply pipe 17, three-dimensional heat recovery heat pipes 6 are evenly distributed on both sides of the middle partition 13, and three-dimensional heat recovery heat pipes 6 A condensed water pan 7 is provided on the top, and the condensed water pan 7 is provided with a drain port 8. A flue gas pipe 14 is connected between the heating side and the exhaust side of the box body 1. The flue gas pipe 14 directs the flue gas from the heating device Delivered to the exhaust air inlet 5, a humidifier 11 is installed at the front end of the heating device 10 near the fresh air outlet 2, and a pipeline 9 is set to connect the condensed water pan 7 with the humidifier 11. A condensate pan 7 is installed at the bottom of the three-dimensional heat recovery heat pipe 6. The moist air discharged from the drying space passes through the heat pipe to exchange heat with the outdoor air to produce a certain amount of condensed water. The condensate pan 7 is connected to the humidifier through the pipe 9. 11, when necessary, use condensed water to humidify the air that is too dry, so as to achieve the recycling of condensed water.
