Description
本發明係有關一種熱交換器排除冷凝水之智能控制系統,尤指一種以二個動力控制閥,配合設備的升溫曲線及蒸氣壓力,以智能控制排除冷凝水之裝置。The present invention relates to an intelligent control system for removing condensed water from a heat exchanger, and more particularly to a device for removing condensed water by intelligently controlling two power control valves in coordination with the temperature rise curve and steam pressure of the equipment.
按,在一些設備中需要用到熱交換器,例如:高溫高壓染色機在染色過程中,需要用到大量蒸氣通過管殼式氣水熱交換器給染色用水加熱,在熱交換過程中,蒸氣冷卻產生大量的高溫冷凝水(condensate water),這部分冷凝水需要及時排出蒸氣管路,否則很多熱量在氣側被冷凝水吸收,氣溫降到水氣兩相點(沸點),這樣就會影響熱交換效果。Heat exchangers are needed in some equipment. For example, in the dyeing process of high-temperature and high-pressure dyeing machines, a large amount of steam is needed to heat the dyeing water through a shell-and-tube gas-water heat exchanger. During the heat exchange process, the steam is cooled to produce a large amount of high-temperature condensate water. This part of the condensate water needs to be discharged from the steam pipeline in time, otherwise a lot of heat will be absorbed by the condensate water on the air side, and the air temperature will drop to the water-gas two-phase point (boiling point), which will affect the heat exchange effect.
次按,由於此等設備需要控制升溫速率,所以蒸氣閥門在控制下開關,造成管內壓力不停的變化,如果有冷凝水的存在,在積水處就會產生水錘作用(Water Hammer,或稱水擊),這樣不僅造成雜訊污染,而且嚴重時對染整設備造成損壞,所以每台染色機都必須加裝卻(祛)水器(Steam trap,或稱疏水閥) ,以便能及時將冷凝水排出。Since such equipment needs to control the heating rate, the steam valve is opened and closed under control, causing the pressure in the pipe to change continuously. If there is condensed water, a water hammer effect (water hammer, or water hammer) will occur at the water accumulation point, which not only causes noise pollution, but also causes damage to the dyeing and finishing equipment in serious cases. Therefore, each dyeing machine must be equipped with a steam trap (steam trap, or drain valve) to discharge the condensed water in time.
如圖1所示,習用一般染色機結構大致包含有:一胴身110,其具有一機頭111及一儲布槽112,且該機頭111內設有一帶布輪113及一噴嘴114;一染液供給單元120,由主泵浦121將加藥泵浦123自加藥桶122抽吸之染液,經輸送管路124送入熱交換器130再送至該噴嘴114;一導布管140,係由該噴嘴114接出至胴身110之機尾,乃與該胴身110形成一供布匹141循環浸染之迴路。As shown in FIG. 1 , the structure of a common dyeing machine generally includes: a
再者,一般染色機之熱交換器130係連接有蒸氣入口131、冷卻水入口132,而由鍋爐(圖未示)提供蒸氣與染液進行熱交換,且熱交換器130係連接有一冷凝水回收管路150,其包括一冷卻水出口151、冷凝水出口152與手動排水口153。Furthermore, the
如圖2所示,係圖1中冷凝水回收管路150的結構放大示意圖,其中該冷凝水出口152裝設有一機械式蒸氣卻水器154,惟查,機械式蒸氣卻水器154是有冷凝水的時候才會排放,因此比較適合用在固定使用蒸氣量的設備,沒有辦法針對變化較大的蒸氣使用量的設備,例如染色機需要靠蒸氣升溫去做熱交換染色的行為,但是蒸氣的來源有時候會高高低低,造成機械式蒸氣卻水器154的作動比較不正常,再者設備升溫的部分,有時候要直接升溫,有時候要階段性升溫,有時候還要保溫,因為有這樣的升溫曲線變化,所以傳統的機械式蒸氣卻水器136,比較不適用而且浪費能源。也就是說,機械式蒸氣卻水器154的最大問題是,排水時會有大量的蒸氣洩漏,其洩漏量如以時間來計算,直徑5mm排水孔在6 bar g蒸氣壓力下,蒸氣洩漏量約為50公斤/小時。就以蒸氣洩漏量一半25公斤/小時為例,如該設備一年運轉50週,一週5天,每天24小時,這個卻水器的蒸氣洩漏量約為150噸/年。目前台灣蒸氣成本約1500元/噸計算,機械式蒸氣卻水器使用一年後,每一個卻水器洩漏金額約新台幣22.5萬元/年。是以,機械式蒸氣卻水器確實無法避免會有蒸氣洩漏的缺失,只是洩漏多或少而已,而且會隨使用時間越長洩漏越多,造成直接能源的浪費。As shown in FIG. 2 , it is an enlarged schematic diagram of the structure of the
本發明人有鑑於上述問題點,乃秉持著精益求精的精神,積極研究改良,以期有效解決習用機械式蒸氣卻水器的缺失。In view of the above problems, the inventor has been adhering to the spirit of continuous improvement and actively researching and improving, in order to effectively solve the shortcomings of conventional mechanical steam dehumidifiers.
