Embodiment 1

[0038] Such as figure 1 As shown, the steam recovery system of this embodiment includes a sizing device 1 and a condensing recovery device 2 connected to the sizing device. The condensing recovery device 2 includes a heat exchange device 3. The heat exchange device 3 has a condensing medium circulation pipeline. The sizing device 1 The steam in the steam enters the heat exchange device 3, exchanges heat with the condensing medium in the condensing medium circulation pipeline, and is completely condensed and recovered within T time.

[0039] The heat exchange device 3 can communicate with the sizing device 1 through pipelines, and the condensing medium pipeline of the heat exchange device 3 is isolated from the passage through which the steam in the heat exchange device 3 passes and performs heat exchange. The condensing medium in the condensing medium pipeline can be water at normal temperature, water cooled to a certain temperature, or other gas or liquid medium, which can pe...

Embodiment 2

[0054] Such as figure 2 As shown, this embodiment is a further limitation of Embodiment 1. The steam recovery system of this embodiment includes a sizing device 1 and a condensation recovery device 2 connected to the sizing device. The steam discharged by the sizing device 1 in a certain period of time All condensate recovery in the condensate recovery device 2.

[0055] The condensation recovery device 2 not only includes a heat exchange device 3, but also includes a storage device. The storage device communicates with the heat exchange device 3 through a pipeline, and the steam in the setting device 1 enters the heat exchange device 3 to condense to a liquid at a temperature of T, and collects into the storage device through the pipeline.

[0056] A plurality of sizing devices 1 are set in the factory area, and each sizing device 1 is provided with a corresponding heat exchange device 3 . The outlet of the exhaust pipeline 5 of each sizing device 1 is connected with the s...

Abstract

The invention discloses a steam recycling system of an acrylic fiber spinning production setting device and a control method. The steam recycling system comprises the setting device and a condensationrecycling device which is communicated with the setting device, and steam which is exhausted by the setting device in a single time is completely condensed and recycled in the condensation recyclingdevice within certain time. The condensation recycling device comprises a heat exchanging device, the heat exchanging device is provided with a condensation medium circulation pipe, and the steam in the setting device enters the heat exchanging device, exchanges heat with condensation mediums in the condensation medium circulation pipe and is completely condensed and recycled within a T period oftime. The steam recycling system can rapidly condense and recycle the steam which is exhausted by the setting device and has high temperature and high enthalpy value within specific time, and direct discharging and subsequent atmosphere thermal pollution are avoided; meanwhile, the high-temperature hot recycled liquid can be also used for a front recycling process, so that steam consumption and desalted water consumption of the front recycling process are reduced, the repeated utilization rate of energy sources is increased, the coal consumption is reduced, and the purposes of protecting the environment and saving energy are achieved.

Description

technical field [0001] The invention belongs to the field of acrylic fiber spinning, and in particular relates to a steam recovery system and a control method of an acrylic fiber spinning production setting device. Background technique [0002] The process of acrylic fiber spinning system uses a shaping device in the spinning process, and uses high temperature, high enthalpy and low pressure steam to shape the tow. During the use of the sizing device, the tow is humidified and heated with direct and indirect steam. The sizing device adopts high temperature and high pressure, and then the steam and condensate in the sizing device need to be discharged quickly, so as to humidify and heat the tow for many times. . [0003] Due to the specific process requirements of the sizing device, the steam tail steam after sizing must be discharged within 90 seconds, otherwise the quality of the sizing tow will be affected. This exhaust method makes it very difficult to recover the steam ...
