Abstract

A novel factory return air system includes a duct system comprising a large-diameter end, a bend end, and an air outlet section connected to the duct. The return air system also includes a dust filter installed at the large-diameter end and an exhaust fan installed at the air outlet section. The beneficial effects of this invention are as follows: The purpose of this invention is to achieve good temperature and humidity control in the factory. By using a dust filter, exhaust fan, and duct in the return air system, the hot air filtered by the dust filter can be discharged into the workshop to increase the workshop temperature, or it can be discharged outdoors, thereby effectively reducing the cost of workshop temperature control and achieving energy conservation.

Description

A new type of factory building return air system

technical field

The utility model relates to the technical field of semi-worsted spinning, in particular to a return air system for a semi-worsted workshop.

Background technique

When the semi-worsted workshop is in use, there are often situations of high negative pressure, low humidity, and low temperature, and the temperature and humidity are difficult to meet the requirements of good production.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings existing in the prior art and provide a new type of factory building return air system. The return air system is used in conjunction with pipes, dust filters and exhaust fans to achieve the purpose of reducing costs and circulating hot air. The technical solution is: a new type of factory building return air system, including a wind pipe, the wind pipe includes a large diameter end, an elbow end and a tuyere section connected with the wind pipe, and it is characterized in that: the return air system also includes a set A dust filter at the large-diameter end and an exhaust fan arranged at the tuyere section.

The technical feature of the utility model also has: the end of the bent pipe is also provided with an exhaust fan.

The beneficial effect of the utility model is that: the purpose of the utility model design is to realize the good temperature and humidity control of the factory building. It can be discharged into the workshop to increase the temperature of the workshop, and can also be discharged outdoors, thereby effectively reducing the cost of temperature control in the workshop and achieving the purpose of energy saving.

Description of drawings

Accompanying drawing 1 is the structural representation of the present utility model, and wherein 1 is a wind pipe, 2 is a large-diameter end, 3 is an elbow end, 4 is a tuyere section, 5 is a dust filter, and 6 is an exhaust fan.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described. The utility model discloses a novel factory building return air system, which comprises a wind pipe 1, a dust filter 5 and an exhaust fan 6. The wind pipe 1 includes a large-diameter end 2, an elbow end 3 and several tuyere sections 4 connected with the wind duct 1, the elbow end 3 leads to the outdoor, and the tuyere section 4 leads to the room. A dust filter 5 is installed at the position of the large-diameter end 2, and an exhaust fan 6 is arranged at the elbow end 3 and the tuyere section 4.

During use, the hot air filtered by the dust filter 5 can be discharged back into the workshop through the air duct 1 and the tuyere section 4 thereon, thereby realizing the reuse of heat energy. When the temperature is high in summer, the hot air is discharged outward through the elbow end 3, so that different design purposes can be achieved through the selection of the exhaust position.

Of course, the above descriptions are not limitations of the present utility model, and the present utility model is not limited to the above-mentioned examples. Changes, modifications, additions or replacements made by those of ordinary skill in the art within the essential scope of the present utility model also belong to Protection scope of the present utility model.

Claims (2)
