HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS

Abstract

Removal of moisture from the compressed air through this system has no welding of pipelines and vessels, no fittings, direction of flow controlled by shuttle valve m echan ism. Two alum inum pressure vessel towers are sealed by tower gasket seal and held together firm ly by a steel tie -rod between top and bottom chambers, shuttle valve mechanism controlling the direction offlow of air. Coalesced water and oil are removed by Borosilicate Prefilter element and purged by auto draint air with water vapour entering top chamber and getting transferred to bottom chamber by inlet tube, air passing through desiccant tower, getting completely dried and desiccant fines being removed by in-built water filter and clean dry-air exiting of the outlet. Water particles trapped in desiccant pores are brought to surface of beads by sudden depressurisation of exhaust valve and is rem oved by purging a 8m all portion of dry air in the shuttle top.

This Invention relates to a "MEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS". This Invention "MEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is for the purpose of removing moisture content from the compressed air. These Dryers are used for Industrial Compressed Air Applications, as the title of the Invention suggests. Conventionally, the compressed air moisture is normally removed by Heatless Desiccant Dryers. This Conventional Desiccant Dryer is made out of welded pressure vessels and fabricated pipelines with flow direction control valves. These fabricated Heatless Desiccant Dryers are heavy in construction and the total size of the Air Dryer is also very large, owmg to the fabricated pipe lines and the huge direction control valves. Further, these Conventional Desiccant Dryers occupy more space and handling of the Dryer is difficult. This Invention "HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is mainly aimed at overcoming these drawbacks. This newly invented "HEATLESS AIR DRYER FOR IDUSTRIAL COMPRESSED AIR APPLICATIONS" is developed without any welding for pressure vessels and pipelines. The flow direction is controlled by a compact Shuttle Valve Assembly. The essence of the Invention "HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is that there is no welding of pipelines and vessels, no fittings, further, direction of flow is controlled by a Shuttle Valve Mechanism, wrapped in an aluminium chamber, consequent to which, this "HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is very compact and is of light weight. The Pressure Vessels, Tower 1 and Tower 2 ( 1 & 2 of Drawing Sheet 1) are made of aluminium and sealed by Tower Seal Gasket ( 3 of Drawing Sheet 1). These vessels are held in position by top and bottom chajnbers made out of aluminium (4 & 5 of Drawing Sheet 1) and fixed firmly by a steel Tie-Rod (6 & 7 of Drawing Sheet I). The direction of flow of air is controlled by the Shuttle Valve Mechanism (Drawing Sheet 2), which is assembled in both, the top and the bottom chambers (4 & 5 of Drawing Sheet 1). Most of the parts of this "MEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" are made of aluminium. So, this Dryer is light in weight and hence is very easy to handle. The Working Principle of this Invention "HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is as follows; Moist air is lead through the Inlet of this Heatless Air Dryer. Coalesced water and oil are removed by Borosilicate Prefilter Element (8 of Drawing Sheet 1) and purged by the Auto Drain (9 of Drawing Sheet 1). Air with water vapour enters the top chamber (5 of Drawing Sheet 1) and is transferred to the Bottom Chamber (4 of Drawing Sheet 1) by Inlet Tube (10 of Drawing Sheet 1). The air passes through the Desiccant Tower 1 (1 of Drawing Sheet 1), gets completely dried (-40 degrees Celsius pressure dewpoint). The Desiccant Fines are removed by in-built after filter (11 of Drawing Sheet 1). Clean and dry air is the outlet. Water particles trapped in the Desiccant Pores art brought to the surface of the beads by sudden depressurisation of Exhaust Valve (12 of Drawing Sheet No:l) mid is removed by purging a small portion of the dry air in the Shuttle top (14 of Drawing Sheet I). In order to avoid pressure spike and desiccant powdering, regenerated tower is re-pressurised by closing the Exhaust Valve (12 of Drawing Sheet 1). The next drying cycle is repeated in Tower 2 (2 of Drawing Sheet 1) and direction of flow is changed by the Shuttle Valve Mechanism (Drawing Sheet 2). The assembly of the Shuttle Valve has been sketched on the Drawing Sheet No.2. The role of the Shuttle Valve Assembly in this newly invented "HEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS" is that it controls the direction of flow. The inlet air is in the middle of the Shuttle Guide (17 of Drawing Sheet 2). The opening and closing of the Exhaust Valve-Tower 1 and Tower 2(13 & 12 of Drawing Sheet No: 2) is controlled by the Controller on time basis (16 of Drawing Sheet 1) . After repressurisation of regenerated tower, both the towers (1 & 2 of Drawing sheet 1) are of equal pressure. When Tower 2 Exhaust valve is opened, sudden depressurisation of Tower 2 leads both the top and bottom shuttle (14 & 15 of Drawing Sheet 1) to move from Tower 1 side to Tower 2 side and seats on the face of the Shuttle Guide (17 of Sheet 1). This results in flow of air getting diverted to Tower 1 (1 of Drawing Sheet 1). The pressure in the Tower 1 gives sealing force, hence there is no leakage in Tower 2 (2 of Drawing Sheet 1). At the same time. Nozzle hole in the top shuttle provides air for cleaning the water particles in the Desiccant surfaces of Tower 2 (2 of Drawing Sheet 1). The cycle repeats and changeover of flow takes place for Tower 2 by opening Tower 1 Exhaust valve (13 of Drawing Sheet 1). I Claim, 1. "MEATLESS AIR DRYER FOR INDUSTRIAL COMPRESSED AIR APPLICATIONS", used for removing moisture content from the compressed air, comprising of two pressure vessel towers (I & 2), which are sealed by Tower Gasket Seal (3) and held together firmly by a steel tie-rod (6 & 7) between the Top and Bottom Chambers (4 & 5), with the Shuttle Valve Mechanism controlling the direction of flow of air, wherein coalesced water and oil are removed by Borosilicate Pre-filter Element (8) and purged by the Auto Drain (9), air with water vapour entering the Top Chamber (5) and getting transferred to the Bottom Chamber (4) by the Inlet Tube (10); air passing through the Desiccant Tower (1) getting completely dried and the desiccant fines being removed by in-built after filter (11) and finally the clean dry air coming out of the outlet; the water particles trapped in the desiccant pores are brought to the surface of the beads by de-pressurising the Exhaust Valve (12) and is removed by purging a small portion of the dry air in the Shuttle Top (14).
