2. Overview of working principle It conducts absorption drying of compressed air through self-heating and slight-heating regeneration method under principle of temperature-pressure swing adsorption. It has Heating-less regeneration (PSA) adsorption type dryer structure is simple, high degree of automation a, Less air consumption than hot regeneration (TSA )dryer,, the depth of the advantage of desorption. To avoid Heating-less regeneration (PSA) adsorption type dryer big air consumption, frequent switching and hot regeneration (TSA )dryer structure is complex、 the power consumption of the big weakness, the comprehensive index has obvious advantages. The double-tower structure is used in The JLAH Adsorption Type Dryer: one tower absorbs moisture in the air at air inlet pressure and low temperature, part of the dry air in another tower regenerate the absorbent in the absorbing tower in the condition of low pressure and high temperature. After a set time, the two towers exchange to ensure the continuous supplying of the dry compressed air. The actual running procedure of each tower is divided into 3 stages: absorb – regenerate— re-pressurize(include heat and cool regenerate). The function of user’s manual is to guide the users how to used this equipment correctly and make daily maintenance. Users should read this manual fluently before using.

3.Technologic Flow The JLAH-Type dryers process flow diagram,Shown in the following diagram. The compressed air enters into Tower A through IA, then the air is desiccated. The desiccated air goes to the outlet from CA, and part of the air is separated as the regenerating air before going to the outlet, after the flow control by RV, then it goes to B from OB after heated by H. There is moisture absorbed in the last half period in B. The regenerating air .brings all these moisture and eliminated by RB and MF. It is the heat reg The JLAH-Type dryers process flow diagram,Shown in the following diagram eneration stage. After a set time, H cut, then the regenerating air cool Tower B for the next half-period. It is the cool regeneration stage. Then, RB closes, Tower B begins to raise the pressure till the pressure of two towers is balanced. It needs time to raise the pressure to ensure the balance of pressure of two towers. Otherwise, it would cause the pressure undulating in the outlet. After half recycling period, IA closes and IB opens. Concerning the time of the procedure that the valve need, RA open again after 6 seconds. Now Tower B begins to dry air, and the Tower A enters the regeneration status, thus an exchange has been finished. After half period working, the Tower B returns to the regeneration status. This period is a recycling time. In a recycling period, each absorbing tower passed 3 stages: absorb – regenerate (include heat and cool regenerate) — re-pressurize. The procedure is controlled by Siemens LOGO!PLC. Air outlet

6.System Disposition In order to ensure the quality of compressed air after the treatment by the dryer and to prolong the lifetime of dryer, the following items should be concerned in the installation: 1) Pre-filter should be installed in the entrance of the dryer to deal with the liquid water, solid particle and oil aerosols. If the liquid water enters directly into the absorbing tower, it would badly damage the running condition of the dryer to greatly raise the dew point in the outlet and even make failure operation of the dryer. And the oil aerosols will extremely pollute the absorbent: not only raise the dew point, but also shorten the life time of the absorbent. To lengthen the service life of the filter, it is recommended that the user from coarse to fine filtering and summarized the way to filter configuration. Recommended configuration the Company production of Grade 9 filter as a coarse filter, After the filtered with a filter, compressed air content of solid and liquid particles 3μm, the oil mist residual content 5ppm. At level Grade 9 filter after , the recommended configuration the company produces the Grade 5 filter as oil filter After the filtered with a filter ,compressed air content of solid and liquid particles 0.01 u m, oil mist residual content of 0.01 PPM. 2).The rubbing of the absorbent will bring some dust. To ensure the clean of the air, normally we should install post-filter. According to the different requirement of the quality degree of the compressed air, users could dispose different post-filter. For the higher using requirement, you could add other filters behind this filter. We recommend you JHF7-grade filter. After the filtered with a filter, compressed air content of solid and liquid particles 1 μm, the oil mist residual content 1ppm. 3). User should put in by-pass valve, closing valve and releasing valve in the system disposition to ensure the successive gas supplying in the lower reaches when it is in the maintenance. 4). Reliable ground-connection set is necessary to be put in this equipment. Figure II System Configuration Diagram

Compressed air dryer operation instructions
4.Model and maintenance
3.1The filters made by our company are the equipment that takes the compressed air as the medium. It is strictly forbidden to run other media directly into the filter. Pay special care not to exceed the specified maximum work. Take special care not to exceed the specified maximum work condition at use. 3.2The filtration precision of the compressed air filter is determined under certain condition. The inlet air quality has obvious influence over the operation effect of the precision filter cores. When necessary the proper prep0sitive filter should be added to make the pretreatment of the inlet air quality. The filter deployment and installation should follow the JLF9 – JLF7 – JLF5 – JLF3 – JLF1 sequence. Otherwise the filtration effect will not be reached and the lifespan of the filter cores will be reduced by big margin. 3.3The filter core is the principal part of the filter. The pressure drop at the filter inlet and outlet should be checked regularly at work. When pressure drop reaches higher than 0.7 Bar, then the work lifespan of the filter core is nearly at the end and the filter or the filter core must be replaced in time (The initial pressure drop of a single filter core is about (0.1‐0.2)Bar. 3.4Should be resistant to chemical causticity. Generally the compressed air does not contain any contaminants harmful to filter cores. However, some hydrocarbon species, acid species, alkali species and some special chemical substances may enter into the filter through compressor under the special circumstances. 3.5Filter must raise or reduce pressure slowly at operation and dismantling of the filter should be performed under the pressure‐free condition. 3.6Replacement of filter cores: Should take care during dismantling or mounting the filter core. Should not hold the filter core barrel with hand to avoid the surface filter material of the filter core from being damaged. 3.7For the filters equipped with manual sewerage, should not open the sewerage under the pressure situation (The filter mounted with automatic sewerage will automatically discharge the accumulated water in the filter barrel). 3.8Should not select filter by the diameter of the fitting pipe, while the air treatment capacity and the usage pressure should be taken for selecting a filter. 3.9By strictly following the above conditions, the use lifespan of the HF9, HF7, HF5, and Hf3 types of filter cores in this series can reach over 8000 hours and that of HF1 type of filter cores will be 2500 hours (It is taken to be the work lifespan limit when the work pressure drop of a single filter core reaches 0.7 Bar).
The operating pressure is 0.7‐1.0MPa, belong to special operating pressure. Alarm: 1、 Please don’t change the drain time that was setted. 2、Please attention drain direction when install organ of catch water, for fear the high‐pressure air to harm people if draining. 3、Suggest use of 4000 hours to replace the filter element.
