蒸呢機在進行操作時按照其材質可以有效的分為碳鋼列管式蒸呢機、不銹鋼列管式蒸呢機和碳鋼與不銹鋼混合列管式冷凝三種。按形式分為固定管板式、浮頭式、U型管式換熱器。按結構分為單管程、雙管程和多管程。傳熱面積0.5-500平方米??筛鶕脩粜枰ㄖ?。適用于在化工、輕工、冶金、制藥、食品、化纖等工業中做各種用途的換熱設備,尤宜于做蒸呢機,代替原有的不銹鋼,搪瓷、石墨、玻璃蒸呢機、使用后效果顯著。

The tube condenser can be effectively divided into three types: carbon steel tube condenser, stainless steel tube condenser and carbon steel and stainless steel mixed tube condenser. It can be divided into fixed tubesheet heat exchanger, floating head heat exchanger and U-tube heat exchanger. According to the structure, it can be divided into single pipe, double pipe and multi-pipe. Heat transfer area is 0.5-500 square meters. It can be customized according to users'needs. It is suitable for heat exchangers used in chemical, light industry, metallurgy, pharmacy, food, chemical fibre and other industries, especially for condensers, instead of stainless steel, enamel, graphite, glass condensers, with remarkable effect after use. 蒸呢機的特點

Characteristic of Tube Condenser

1.耐腐蝕性:聚丙烯具有優良的耐化學品性,對于無機化合物,不論酸,堿、鹽溶液,除強氧化性物料外,幾乎直到100℃都對其無破壞作用,對幾乎所有溶劑在室溫下均不溶解,一般烷、徑、醇、酚、醛、酮類等介質上均可使用。

1. Corrosion resistance: Polypropylene has excellent chemical resistance. For inorganic compounds, no matter acid, alkali or salt solution, it has no destructive effect on inorganic compounds except strongly oxidizing materials, and almost all solvents are insoluble at room temperature. Generally, alkanes, alcohols, phenols, aldehydes, ketones and other mediums can make polypropylene insoluble. Use.

2.耐溫性:聚丙烯塑料熔點為164-174℃,因此一般使用溫度可達110-125℃。

2. Temperature Resistance: The melting point of polypropylene plastics is 164-174 C, so the general temperature of use can reach 110-125 C.

3.無毒性:不結垢,不污染介質,也可用于食品工業。

3. Non-toxicity: non-scaling, non-polluting media, can also be used in the food industry.

4.重量輕:對設備安裝維修極為方便。

4. Light weight: very convenient for installation and maintenance of equipment.

蒸呢機是制冷、冶金、化工等行業的主要熱交換器之一,在蒸呢機中應用。事實上,列管式蒸呢機是一種節能、節能的新裝置,在化工行業中有了應用。

Tube condenser is one of the main heat exchangers in refrigeration, metallurgy, chemical industry and other industries. It is used in condenser. In fact, tubular condenser is a new energy-saving device, which has been applied in chemical industry.

在蒸呢機的運行過程中,比例尺和塵垢,因為它的蒸汽蒸騰作用機理,比其他種類的柱管蒸呢機更容易污染??紤]蒸呢機的保護問題是如何處理蒸呢機的伸縮。管式蒸呢機在室外操作,由于蒸騰作用,管道外部的水容易被腐蝕。為了解決這一現象,管式蒸呢機的上下箱應滿足鋅厚的要求。由于管內的水不斷蒸發,易于伸縮,大大降低了柱管蒸呢機的傳熱效率。因此,可以采用以下方法處理柱管蒸呢機污垢的問題。


During the operation of tube condenser, scale and dust are more easily polluted than other types of tube condenser because of its steam transpiration mechanism. Considering the protection of condenser is how to deal with the expansion of condenser. Tube condenser is operated outdoors. Because of transpiration, water outside the pipeline is easy to be corroded. In order to solve this problem, the upper and lower boxes of tubular condensers should meet the requirement of zinc thickness. Because of the continuous evaporation of water in the tube, it is easy to expand and shrink, which greatly reduces the heat transfer efficiency of the column-tube condenser. Therefore, the following methods can be used to deal with the fouling problem of the column condenser.

蒸呢機的正常運行中,在使用時需要保持設備管路的清潔的重要性,這樣可以保護蒸呢機的保護。選擇懸臂式管殼式蒸呢機,主機在啟動的過程中停止,因為有一個壓差和殼管式蒸呢機線圈溫度差異,壓差和溫度差異會導致銅連續彈性效應,規模為銅,質量,和不同的膨脹系數非常大,所以懸臂式管殼式蒸呢機清洗的功能活躍。在運行過程中,由于制冷劑在管蒸呢機的兩個階段中有較高的頻率感覺,很難形成伸縮,使其無法粘附在墻上。在蒸呢機的制造過程中,應進行預膜污染,以防止塵垢晶體粘附在銅管外。


In the normal operation of tube condenser, it is important to keep the equipment pipeline clean when using, so as to protect the condenser. Selecting the cantilever shell-and-tube condenser, the main engine stops in the start-up process, because there is a pressure difference and the temperature difference of shell-and-tube condenser coil, the pressure difference and temperature difference will lead to the continuous elastic effect of copper, the scale of copper, mass, and different expansion coefficients are very large, so the cleaning function of cantilever shell-and-tube condenser Active. During operation, because refrigerant has a high frequency sense in the two stages of tube condenser, it is difficult to form expansion, which makes it impossible to adhere to the wall. Pre-membrane fouling should be carried out in the manufacturing process of condenser to prevent dust crystals from adhering to copper tubes.

選擇少量排水設備,控制一定范圍內循環水鈣離子濃度,以避免水垢??梢栽O置預冷器和使管殼式蒸呢機管蒸騰的外表溫度在50℃下,選擇大密集水分配裝置,確保管殼式蒸呢機管外觀小時電影被水覆蓋,不干燥。當熱交換盤管外表的溫度小于50℃,寬松的規模和質量,容易清洗,當外部溫度高于50℃,襲擊的規模和質量強,難以根除。水板設置好,可以用來防止蒸呢機冷凝。


Select a small amount of drainage equipment to control the concentration of calcium ion in circulating water within a certain range to avoid scale. It is possible to set up a pre-cooler and make the tube of shell-and-tube condenser transpire at the surface temperature of 50 C, and select a large-density water distribution device to ensure that the film is covered by water and not dry when the tube is small. When the external temperature of the heat exchange coil is less than 50 C, the scale and quality of the coil are loose and easy to clean. When the external temperature is higher than 50 C, the scale and quality of the attack are strong and difficult to eradicate. The water plate is set up to prevent the condenser from condensing.
