　　HHS-1 asphalt trichloroethylene recovery instrument operating procedures:

　　★Turn on the power and connect the inlet and outlet water to the still with a hose.

　　★Put the solution to be recovered into the distillation chamber,and pour A into a large volume of about 10 liters at a time.

　　★With cooling water,close the main power switch,the red power indicator light is on,press the heating button,the heating indicator light is on,the instrument starts to work,and enters the heating state.

　　★When the instrument is completed with distillation,the main power should be cut off in time at this time.

　　★The operator observes the liquid level in the glass tube through the liquid level gauge.If the liquid level of the asphalt is seen,the right side water nozzle should be opened to stop the asphalt liquid.When the liquid level of the left level gauge reaches the upper limit position,the water nozzle should be opened in time to discharge the recovered solution.

　　★The temperature switch in the thermostat can be adjusted according to the different boiling points of different solvents.The control temperature of this instrument has been adjusted according to the temperature of trichloroethylene(86°)when leaving the factory.Do not change it at will,such as doing other When bitumen solvents are used,the boiling point temperature should be mastered and adjusted.

　　HHS-1沥青三氯乙烯回收仪工作原理：

　　当电加热通电后，电能通过电阻丝转变成热能，使置于溶器中的三氯乙稀沥青溶液升温。当溶液的温度达到三氯乙稀溶剂的沸点时（86.7℃）三氯乙稀通过分子运动将液体转变成气体蒸发出来，此时沥青油及其它杂质由于沸点高，仍滞留在溶液中，蒸发过程是一个加热过程，尽管电加热器仍在工作，溶液的温度也不会升高，当溶液中的三氯乙稀全部被蒸发掉时，剩下的沥青液的温度才会升高，此时电源通过温度控制开关自动切断，加热器停止工作，沥青液滞留在容器右腔，三氯乙稀气体通过容器上部的空间进入左腔，左腔的冷却循环水使三氯乙稀蒸气分子遇冷，温度下降，重新变成液体留在左腔，这样**完成了三氯乙稀的回收工作。

　　HHS-1 asphalt trichloroethylene recovery instrument works:

　　When the electric heating is energized,the electric energy is converted into heat energy through the resistance wire,so that the trichloroethylene pitch solution placed in the dissolver is heated.When the temperature of the solution reaches the boiling point of trichloroethylene solvent(86.7°C),trichloroethylene will evaporate the liquid into gas through molecular movement.At this time,the bitumen oil and other impurities will remain in the solution and evaporate due to the high boiling point.The process is a heating process.Although the electric heater is still working,the temperature of the solution will not rise.When all the trichloroethylene in the solution is evaporated,the temperature of the remaining asphalt liquid will rise.At that time,the power is automatically cut off by the temperature control switch,the heater stops working,the asphalt liquid is trapped in the right cavity of the container,and the trichloroethylene gas enters the left cavity through the space in the upper part of the container.It is cold,the temperature drops,and it becomes a liquid again and stays in the left cavity,so that the recovery of trichloroethylene is completed.

　　HHS-1沥青三氯乙烯回收仪仪器结构：

　　容器全部由不锈钢制成，分为两室，蒸馏室位于右侧，储存室（包括冷凝器）位于左侧。蒸馏室的容积约为10升，储存室的容积为6升，容器下部各有一水咀，右侧为放出沥青溶液的水咀，左侧为放出已回收溶剂的水咀，蒸馏室下部设有二组电阻丝式加热器。

　　冷凝器位于左侧储存室的上部。由8层盘管组成，直接与自来水连接进行冷却，上盖用耐腐蚀胶圈密封，防止三氯乙稀的蒸发气体跑出，污染工作环境，温控器位于电器盒内，温控器触头与加热介质接触，到设定温度时立即断电，整个过程自动完成。

　　在壳体的前面装有两支液位计，右侧的液位计主要用来检查倒入待回收的液体，蒸馏完毕，如液位计仍能看到残留余液的液面，**在打开右侧水咀把残留的液体放出，如左侧的液位计上的液面达到了上限的位置**要打开左侧水咀，放出已清洁的三氯乙稀液体。

　　漏斗中设有一个筛网，防止颗粒状物体进入蒸馏室。漏斗咀中部设有一个防溅网，防止在倒入污染的液体时溅入右侧。电器盒下部设有绝缘盖板防止人员触电。

　　HHS-1 asphalt trichloroethylene recovery instrument structure:

　　The vessel is made entirely of stainless steel and is divided into two chambers,with a distillation chamber on the right and a storage chamber(including the condenser)on the left.The volume of the distillation chamber is about 10 liters,and the volume of the storage chamber is 6 liters.There is a water nozzle at the bottom of the container,a water nozzle that discharges the asphalt solution on the right side,and a water nozzle that releases the recovered solvent on the left side.Two sets of resistance wire heaters.

　　The condenser is located in the upper part of the left storage compartment.It consists of 8 layers of coils.It is directly connected to the tap water for cooling.The upper cover is sealed with a corrosion-resistant rubber ring to prevent the trichloroethylene evaporated gas from running out and pollute the working environment.The thermostat is located in the electrical box.The head is in contact with the heating medium,and the power is immediately turned off when the set temperature is reached,and the entire process is automatically completed.

　　There are two level gauges on the front of the casing.The level gauge on the right is mainly used to check the liquid to be recovered.After the distillation is completed,if the level gauge can still see the remaining liquid level,**Open the water nozzle on the right side to discharge the remaining liquid,such as the position where the liquid level on the left-side level gauge reaches the upper limit.

　　A sieve is installed in the funnel to prevent granular objects from entering the distillation chamber.A splash screen is provided in the middle of the funnel to prevent splashing to the right when contaminated liquid is poured.The lower part of the electrical box is provided with an insulating cover to prevent electric shock.

　　HHS-1沥青三氯乙烯回收仪注意事项：

　　1、要随时抽查被蒸馏溶剂的PH值，（氯化的碳氢化合物）。如PH值低于5时，回收器的整个内部要被损坏，在这种情况下，要及时清洗蒸馏室。

　　2、仪器使用时外皮接地。

　　3、仪器工作时，不要离人。

　　4、清理仪器时，应拔掉电源插头，并防止水浸入电器元件。

　　1.Always check the pH of the solvent being distilled,(chlorinated hydrocarbons).If the pH value is below 5,the entire interior of the recoverer will be damaged.In this case,the distillation chamber should be cleaned in time.

　　2.The skin of the instrument is grounded during use.

　　3.When the instrument is working,do not leave the person.

　　4.When cleaning the instrument,unplug the power plug and prevent water from entering the electrical components.
