DZ型电热蒸馏器使用方便，操作简单，更具特色的采用优质进口不锈钢材料、经过特殊处理，精心加工而成。这不仅充分保证了蒸馏水的质量，而且也大大提高了使用寿命。

DZ Electrothermal Distillatory is employed to electrically heat potable tap water for producing pure water with distillation method for use by medical and hygienic departments, pharmaceutical and electroplating industries, lab. and others. The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

DZ Electrothermal Distillatory is easy to use and simple in operation .The most important feature is that it is made up of the imported quality stainless steel and is subject to special treatment and meticulous machining, which fully ensures the quality of distilled water and significant increase its service life .

二、结构特点

II. Structural Features

本产品主要由不锈钢蒸发锅、冷凝器、电气装置三部分组成。

This product is mainly composed of stainless steel evaporation pan, condenser and electric installation.

（一）蒸发锅：

(I) Evaporation pan:

本部件用优质不锈钢薄板，经过滚压，延伸与先进的焊接方法加工而成，锅内水位超过限定位置能自动溢出、锅身与锅盖有气密装置。设有挡帽，能有效地防止蒸气 带水滴而影响蒸馏水质。锅内水垢可用酸、液洗刷，清除方便彻底，锅右侧装有放水旋塞。可随时放去存水。

This component is fabricated of high quality stainless steel sheet through rolling, extension and advanced welding technique. The water will automatically flow out in case the water level inside the pan exceeds the limit. Pan body and cover are provided with airtight device. Barrier cap is designed to effectively prevent the steam with drip influencing the distilled water quality. The scale inside the pan can be conveniently and thoroughly removed through acid and liquid. With the drain cock at the right side of evaporation pan, the cumulated water can be drained at any time.

（二）冷凝器：

(II) Condenser

本部件用优质不锈钢薄板和国际流行的不锈钢盘管制成，结构合理，热交换率高，且易于拆卸，便于洗刷内部水垢。

This component is made of high quality stainless steel sheet and international pop stainless steel coil, featuring rational structure, high heat-exchange efficiency, removal easiness and convenient removal of internal scale.

（三）加热部分：

(III) Heating section:

本部件由浸入式电热管组成，电热管为T4紫铜护套；表面镀以纯锡；经久耐用；安装在蒸发锅内部底。

This component is composed of immersion type heating tube with T4 red copper sleeve plated with pure tin for long service life. It is mounted at the internal bottom of evaporation pan.

使用时切勿断水！

Do not cut off the water flow during operation!

三、使用方法

III. Operation Method

1、先将防水阀（7）关闭。

1. Turn off water prevention valve (7) first.

2、开启水源阀（1）使自来水从进入控制阀（4）进入冷凝器（3）再从回水管流入漏斗后，注入蒸发锅（6）。直至水位上升到玻璃水位窗（5）中心处。待水位放水管（10）流出且其水位停止上升时，可暂时将水源阀（1）关闭。

2. Open water supply valve (1) to enable the tap water flow into condenser (3) from control valve (4) and then to evaporation pan (6) through after flowing into hopper via return pipe until the water level rises to the middle of water level window (5). The water supply valve (1) can be closed temporarily when the water flows out from discharge pipe and the water level stops rising.

3、接通电源，等到锅内的饿水已沸腾，再开启水源阀（1）。但应注意水流不宜过大过小，应从小到大逐渐开启水源阀门，调即到蒸馏水出大量****，加水杯有小量溢出为宜。蒸馏水温度为40oC左右。

3. Turn on the power supply and open the water supply valve (1) again when the water in pan boils. It should be noted that the water flow shall not be excessively high or low. For this, the water supply valve shall be opened gradually from “low” to “high”. It is recommended that output of distilled water reach the peak level and there should be a small quantity of overflow at the water cup. The temperature of distilled water is around 40℃.

4、蒸馏水出水皮管不宜过大，并切勿插入蒸馏水容器之中皮管使用前应洗刷洁净并用蒸馏水重洗，且应保持畅通以防止窒塞蒸汽而造成漏水溢水

4. The outlet hose of distilled water shall not be over-sized, and shall not be inserted into distilled water container. Before use, the hose shall be cleaned and then washed again with distilled water. It shall maintain a smooth flow so as to prevent the leakage and overflow due to cumulated steam.

5、冷凝器外壁有烫手感，为正常，否则将无蒸馏水流出。

5. It is normal to feel hot at the outside wall of condenser. Otherwise, it means no distilled water flows out.
