Description

Technical Field

[0001] The utility model relates to the technical field of dyeing equipment, in particular to an energy consumption optimization device for a stenter. Background Art

[0002] Since the dyed and rinsed textiles need to be dried, stretched and heat-treated in a stenter, a large amount of heat is required to dry and shape the fabric. In the existing stenter process, a large amount of high-temperature steam is usually directly introduced into the stenter chamber, and the air is heated by convective heat transfer through a steam heater to take away the moisture in the fabric and the fabric is heated by radiative heat transfer, so as to realize the drying, heating and shaping of the fabric. The energy utilization in this process is relatively extensive, without considering the specific process in different stages of fabric shaping, as well as the quantity and quality of the required heat, and more importantly, no reasonable heating measures are adopted accordingly. Therefore, the utilization efficiency of heat is low. At present, there is still much room for significant reduction in the heating energy consumption of most stenters. Therefore, we propose an energy consumption optimization device for a stenter. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem of high energy consumption of the existing stenter, and to propose an energy consumption optimization device for a stenter.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] The energy consumption optimization device for a stenter includes a heating chamber, a chamber partition, a steam inlet main pipe, a steam inlet branch pipe, a condensate pipe, a steam outlet pipe, an exhaust gas extraction pipe, a steam valve, a temperature detector, a humidity detector, a hot air valve, a hot air inlet main pipe, a hot air inlet branch pipe and a steam heater. The heating chamber is relatively isolated by the chamber partition. After isolation, there are a total of ten chambers numbered 1# - 10# inside the heating chamber. The hot air inlet main pipe is connected to the hot air inlet branch pipe, and the hot air inlet branch pipe is connected to both sides of each chamber in the heating chamber through the hot air valve. The hot air valve adjusts the hot air flow rate into each chamber according to the temperature and humidity inside each chamber. The exhaust gas extraction pipe is installed at the top of each heating chamber, and the gas inside each chamber is extracted to the exhaust gas treatment system through the exhaust gas extraction pipe. The steam inlet main pipe is connected to the steam inlet branch pipe, and the steam inlet branch pipe is connected to chambers 5# - 10# through the steam valve. The steam enters the heating chamber from top to bottom. The outlet of the steam heater in chamber 5# is connected to the steam heater in chamber 4#, the outlet of the steam heater in chamber 4# is connected to the steam heater in chamber 3#, the outlet of the steam heater in chamber 3# is connected to the steam heater in chamber 2#, and the outlet of the steam heater in chamber 2# is connected to the steam heater in chamber 1#. The condensate pipe is connected to chambers 6# - 10#, and the steam outlet pipe is connected to chamber 1#. The steam in chamber 1# is discharged through the condensate pipe, and the steam inside chambers 6# - 10# is discharged to the remaining steam-using links.

[0006] In a possible design, heat-insulating layers are provided on the exteriors of all heating chambers, the steam inlet main pipe, the steam inlet branch pipes, the steam outlet pipe, the waste gas extraction pipe, the hot air inlet main pipe, the hot air inlet branch pipes, and the steam heater. The thickness of the heat-insulating layer is made different according to the internal air flow temperature, so that the surface temperature of the heat-insulating layer is less than 40°C.

[0007] In a possible design, the chamber partition only isolates the gases in each chamber inside the heating chamber and does not prevent the normal movement of the fabric between the chambers.

[0008] In a possible design, a temperature detector and a humidity detector are installed inside each chamber in the heating chamber for real-time detection of the temperature and humidity data inside the chamber.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0014] Embodiment 1

[0015] Refer to Figure 1-2, specifically a setting machine energy consumption optimization device, including a heating chamber 1, a chamber partition 11, a steam inlet main pipe 2, steam inlet branch pipes 3, a condensate water pipe 5, a steam outlet pipe 4, an exhaust gas extraction pipe 6, a steam valve 7, a temperature detector, a humidity detector, a hot air valve 8, a hot air inlet main pipe 9, hot air inlet branch pipes 10 and a steam heater 12, characterized in that the heating chamber 1 is relatively isolated by the chamber partition 11. After isolation, there are ten chambers numbered 1# - 10# inside the heating chamber 1. The hot air inlet main pipe 9 is connected to the hot air inlet branch pipes 10, and the hot air inlet branch pipes 10 are connected to both sides of each chamber in the heating chamber 1 through the hot air valve 8. The air valve 8 adjusts the hot air flow rate into each chamber according to the temperature and humidity inside each chamber. The exhaust gas extraction pipe 6 is installed at the top of each heating chamber 1, and the gas inside each chamber is extracted to the exhaust gas treatment system through the exhaust gas extraction pipe 6. The steam inlet main pipe 2 is connected to the steam inlet branch pipes 3, and the steam inlet branch pipes 3 are connected to chambers 5# - 10# through the steam valve 7. Steam enters the heating chamber 1 from top to bottom. The outlet of the steam heater 12 in chamber 5# is connected to the steam heater 12 in chamber 4#, the outlet of the steam heater 12 in chamber 4# is connected to the steam heater 12 in chamber 3#, the outlet of the steam heater 12 in chamber 3# is connected to the steam heater 12 in chamber 2#, and the outlet of the steam heater 12 in chamber 2# is connected to the steam heater 12 in chamber 1#. The condensate water pipe 5 is connected to chambers 6# - 10#, and the steam outlet pipe 4 is connected to chamber 1#. The steam in chamber 1# is discharged through the condensate water pipe 5, and the steam inside chambers 6# - 10# is discharged to the remaining steam - using links.

[0016] Hot air heated to 150 °C by an external heat source is split through 2 hot air inlet main pipes 9 and 20 hot air inlet branch pipes 10 and enters each chamber through the air inlet openings on both sides of each chamber in the heating chamber 1. There are 10 hot air inlet branch pipes 10 installed on each hot air inlet main pipe 9. The hot air valve 8 located on the hot air inlet branch pipe 10 adjusts the valve according to the temperature and humidity inside the heating chamber 1 to control the hot air flow rate into each chamber. Among them, the main function of heating chambers 1 - 5 is to dry the fabric, and the demand for hot air is relatively large. The opening degrees of the hot air valves 8 in chambers 1# - 5# are adjusted to the maximum, and the opening degrees of the hot air valves 8 in the remaining chambers are 50%, so as to introduce more hot air into chambers 1# - 5#. The exhaust gas generated in each chamber is extracted to the exhaust gas treatment system through the exhaust gas extraction pipe 6 above the chamber.

[0017] Steam at 260°C and 1.5 MPa in the steam main pipe is divided through 6 steam inlet branch pipes 3 and enters the 5# to 10# chambers respectively. The steam valve 7 on the steam inlet branch pipe 3 adjusts the steam valve 7 according to the internal temperature of the heating chamber 1 to control the steam intake and keep the temperature in the 6# to 10# chambers stable at the working temperature of 200°C. According to the temperature and humidity of the flowing gas in the 5# chamber, with the absolute humidity <5% and the temperature >150°C, the opening of the steam inlet valve at the 5# chamber is adjusted. After the steam inside the 6# to 10# heating chambers 1 releases heat inside the steam heater 12, the temperature drops to above 150°C, and then it is discharged into other steam-using links in the printing and dyeing factory through the condensate pipe 5. After the steam releases heat inside the steam heater 12 in the 5# chamber, it is introduced into the steam heater 12 inside the 4# heating chamber for secondary utilization. After the steam inside the 4# chamber releases heat in the steam heater 12 of the 4# chamber, it enters the steam heater 12 of the 3# chamber from the outlet of the 4# steam heater 12. After the steam releases heat in the steam heater 12 of the 3# chamber, it enters the steam heater 12 of the 2# chamber from the outlet of the 3# steam heater 12. After releasing heat in the steam heater 12 of the 2# chamber, it enters the steam heater 12 of the 1# chamber. After the steam inside the 1# heating chamber releases heat, it is discharged through the steam outlet pipe 4.
