Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical fiber spinning, in particular to an energy-saving side-blowing air-conditioning system for chemical fibers. Background Art
[0002] During the chemical fiber spinning process, the fiber filaments coming out of the spinneret need to be cooled by side blowing. Existing chemical fiber spinning production lines are all equipped with a side-blowing air-conditioning system. However, during the production of sliced chemical fibers, there may be a situation of insufficient orders, resulting in the shutdown of several screw extruders in a line. When only one-third or less than one-third of the screw extruders in a line are working, if the side-blowing air-conditioning of this line is turned on and operated, due to the small load, the energy consumption per ton of silk will be very high, thus increasing the production cost. Content of the Utility Model
[0003] The purpose of the utility model is to provide an energy-saving side-blowing air-conditioning system for chemical fibers. By arranging a bypass pipe between two adjacent side-blowing air-conditioning devices, it can borrow the side-blowing air-conditioning device of the bypass line for cooling when only a small number of screw extruders in a line are working normally, and the energy consumption when orders are insufficient can be reduced.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions:
[0005] An energy-saving side-blowing air-conditioning system for chemical fibers includes two relatively close side-blowing air-conditioning devices. The side-blowing air-conditioning device includes a refrigeration air-conditioning unit. The air outlet end of the refrigeration air-conditioning unit is connected with a main air duct. Each main air duct is connected with a plurality of side-blowing air boxes arranged in parallel through a plurality of branch pipes; an adjusting valve is arranged at one end of the main air duct close to the refrigeration air-conditioning unit;
[0006] A bypass pipe is arranged between the main air ducts of the two side-blowing air-conditioning devices, and a first valve is arranged on the bypass pipe.
[0007] When there is an insufficient order, the first line works normally, and only one-third or less than one-third of the screw extruders in the second line work normally. At this time, open the first valve, connect the main air ducts of the two side-blowing air-conditioning devices through the bypass pipe, and then slowly close the adjusting valve at the air outlet end of the refrigeration air-conditioning unit of the second line. The cold air of the refrigeration air-conditioning unit of the first line enters the main air duct of the second line through the bypass pipe, so as to supply cold air to the side-blowing air boxes corresponding to the remaining working screw extruders in the second line. Because the air conditioner generally has surplus air volume, adding a small part basically will not be affected. When the production capacity does not exceed 1 / 3, use the air conditioner of the bypass line. When it exceeds 1 / 3, turn on the air conditioner of its own line. Thus, when the energy is insufficient, compared with the situation of producing a small amount of products by turning on only one air conditioner alone, the energy consumption is greatly reduced.
[0008] The present utility model is further configured such that: a second valve is provided on the branch pipe. When only one-third or less than one-third of the screw extruders on the second line are operating, before opening the first valve of the bypass pipe, first close the second valve of the branch pipe of the side air blowing box corresponding to the non-operating screw extruder on the second line. The second valve can be used to individually control a single side air blowing box.
[0009] The present utility model is further configured such that: the number of side air blowing boxes of a side air blowing air conditioning device is not less than 6.
[0010] The present utility model is further configured such that: two side air blowing air conditioning devices are arranged back to back, which can reduce the distance between the two main air ducts and reduce energy loss.
[0011] The present utility model is further configured such that: a heat insulation sleeve is provided on the outer side of the main air duct, and there is a spacing between the inner wall of the heat insulation sleeve and the outer wall of the main air duct.
[0012] A heat preservation material is clamped between the inner wall of the heat insulation sleeve and the outer wall of the main air duct. By providing the heat insulation sleeve and the heat preservation material, the heat exchange between the main air duct and the outside temperature can be reduced, thereby further reducing energy consumption.
[0013] The outstanding effect of the present utility model is:
[0014] Compared with the prior art, by providing a bypass pipe between two adjacent side air blowing air conditioning devices, the side air blowing air conditioning device on the bypass line can be borrowed for cooling when only a small number of screw extruders on one line are operating normally, and the energy consumption when the order is insufficient can be reduced.

[0020] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.
[0021] The following reference Figures 1 to 3 is used to describe the present utility model:
[0022] An energy-saving chemical fiber side-blowing air-conditioning system includes two side-blowing air-conditioning devices 10 arranged closely. The side-blowing air-conditioning device 10 includes a refrigeration air-conditioning unit 101. The air outlet end of the refrigeration air-conditioning unit 101 is connected to a main air duct 102. A plurality of side-blowing boxes 104 arranged in parallel are connected to each main air duct 102 through a plurality of branch pipes 103; an adjusting valve is provided at one end of the main air duct close to the refrigeration air-conditioning unit;
[0023] A bypass pipe 20 is provided between the main air ducts 102 of the two side-blowing air-conditioning devices 10, and a first valve 21 is provided on the bypass pipe 20.
[0024] When there is insufficient order, the first line operates normally, and only one-third or less than one-third of the screw extruders on the second line operate normally. At this time, the first valve is opened, and the main air ducts of the two side-blowing air-conditioning devices are connected through the bypass pipe. Then, the adjusting valve at the air outlet end of the refrigeration air-conditioning unit on the second line is slowly closed. The cold air from the refrigeration air-conditioning unit on the first line enters the main air duct of the second line through the bypass pipe, so as to supply cold air to the side-blowing boxes corresponding to the remaining working screw extruders on the second line. Because the air conditioner generally has surplus air volume, adding a small amount basically has no impact. When the production capacity does not exceed 1 / 3, the air conditioner on the bypass line is used, and when it exceeds 1 / 3, the air conditioner on its own line is turned on. Thus, when the production capacity is insufficient, compared with the situation of producing a small amount of products by turning on only one air conditioner alone, the energy consumption is greatly reduced.
[0025] A second valve 105 is provided on the branch pipe 103. When only one-third or less than one-third of the screw extruders on the second line are working, before opening the first valve on the bypass pipe, first close the second valve on the branch pipe of the side-blowing box corresponding to the non-working screw extruder on the second line. The individual side-blowing boxes can be controlled separately through the second valve.
[0026] The number of side-blowing boxes 104 of one side-blowing air-conditioning device 10 is not less than 6.
[0027] The two side-blowing air-conditioning devices 10 are arranged back to back, which can reduce the distance between the two main air ducts and reduce energy loss.
[0028] A heat-insulating sleeve 106 is provided on the outer side of the main air duct 102, and a gap is provided between the inner wall of the heat-insulating sleeve 106 and the outer wall of the main air duct 102.
[0029] A heat-insulating material is clamped between the inner wall of the heat-insulating sleeve 106 and the outer wall of the main air duct 102, and the heat-insulating material can be asbestos. By providing the heat-insulating sleeve and the heat-insulating material, the heat exchange between the main air duct and the outside temperature can be reduced, thereby further reducing energy consumption.
[0030] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications made under the above assumptions should also be regarded as the protection scope of the present invention.
