列管冷凝器在进行操作时按照其材质可以有效的分为碳钢列管式冷凝器、不锈钢列管式冷凝器和碳钢与不锈钢混合列管式冷凝三种。按形式分为固定管板式、浮头式、U型管式换热器。按结构分为单管程、双管程和多管程。传热面积0.5-500平方米。可根据用户需要定制。适用于在化工、轻工、冶金、制药、食品、化纤等工业中做各种用途的换热设备,尤宜于做冷凝器,代替原有的不锈钢,搪瓷、石墨、玻璃冷凝器、使用后效果显著。

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. 列管冷凝器的特点

Characteristic of Tube Condenser

1.耐腐蚀性:聚丙烯具有优良的耐化学品性,对于无机化合物,不论酸,碱、盐溶液,除强氧化性物料外,几乎直到100℃都对其无破坏作用,对几乎所有溶剂在室温下均不溶解,一般烷、径、醇、酚、醛、酮类等介质上均可使用。

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.耐温性:聚丙烯塑料熔点为164-174℃,因此一般使用温度可达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.无毒性:不结垢,不污染介质,也可用于食品工业。

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

4.重量轻:对设备安装维修极为方便。

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

列管冷凝器是制冷、冶金、化工等行业的主要热交换器之一,在冷凝器中应用。事实上,列管式冷凝器是一种节能、节能的新装置,在化工行业中有了应用。

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.

在列管冷凝器的运行过程中,比例尺和尘垢,因为它的蒸汽蒸腾作用机理,比其他种类的柱管冷凝器更容易污染。考虑冷凝器的保护问题是如何处理冷凝器的伸缩。管式冷凝器在室外操作,由于蒸腾作用,管道外部的水容易被腐蚀。为了解决这一现象,管式冷凝器的上下箱应满足锌厚的要求。由于管内的水不断蒸发,易于伸缩,大大降低了柱管冷凝器的传热效率。因此,可以采用以下方法处理柱管冷凝器污垢的问题。

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.

列管冷凝器的正常运行中,在使用时需要保持设备管路的清洁的重要性,这样可以保护冷凝器的保护。选择悬臂式管壳式冷凝器,主机在启动的过程中停止,因为有一个压差和壳管式冷凝器线圈温度差异,压差和温度差异会导致铜连续弹性效应,规模为铜,质量,和不同的膨胀系数非常大,所以悬臂式管壳式冷凝器清洗的功能活跃。在运行过程中,由于制冷剂在管冷凝器的两个阶段中有较高的频率感觉,很难形成伸缩,使其无法粘附在墙上。在冷凝器的制造过程中,应进行预膜污染,以防止尘垢晶体粘附在铜管外。

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.

选择少量排水设备,控制一定范围内循环水钙离子浓度,以避免水垢。可以设置预冷器和使管壳式冷凝器管蒸腾的外表温度在50℃下,选择大密集水分配装置,确保管壳式冷凝器管外观小时电影被水覆盖,不干燥。当热交换盘管外表的温度小于50℃,宽松的规模和质量,容易清洗,当外部温度高于50℃,袭击的规模和质量强,难以根除。水板设置好,可以用来防止冷凝器冷凝。

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.
