KR20090018183A - DESIGN AND MANUFACTURE OF HIGH PRESSURE TOWER FOR 400KG/cm^2, 170 m^2?H, D.P. -63°C DESICCANT AIR DRYER - Google Patents

Abstract

Pressure vessel design and the manufacturing method which is used for the pressure 400kg/cm^2, the capacity 170 m^3/h, and the adhesion type air drier of the dew point temperature -63°C disassembling and assembling are provided that the permanent strength is maintained even compression and expansion according to the change of temperature and pressure and intensity change. A pressure vessel manufacturing method which is used for the pressure 400kg/cm^2, the capacity 170 m^3/h, and the adhesion type air drier of the dew point temperature -63°C disassembling and assembling comprises as follows. The pressure vessel which consecutively can maintain airtight in compression and expansion generation according to the pressure gradient (0~400kg/cm2) and temperature change (room temperature~175°C) is included. The pressure vessel has the size which is suitable for the capacity of pressure more than 400 kg / cm2G and 100 cfm (170m3/hr), and the dew point temperature -63°C.

Description

Design and manufacture of High Pressure Tower for 400㎏ ／ ㎠, 170 ㎥ / ｈ for pressure adsorption air dryer with pressure 400㎏ ／ ㎠, capacity 170 ㎥ / ｈ, dew point temperature -63 ℃ , DP -63 ℃ Desiccant Air Dryer}

Common air dryers are either refrigerated or adsorptive. They are refrigerated at temperatures above 3 degrees and adsorptive when dew point temperatures below are required.

New technology is applied in developing and supplying adsorption dryer suitable for pressure 400kg / cm2, capacity 100 cfm (170 ㎥ / ｈ), dew point temperature -63 ℃, and continuous operating conditions developed according to the requirements of the user.

The pressure vessel applied to this time is divided into the pressure vessel and the related piping and control valve and control device which are not applied by the Industrial Safety and Health Act or the High Pressure Gas Safety Management Act, and the filter type of the inlet / outlet. There are several different ways of playing.

In the case of the development of this special high-pressure dryer, it is a product that is designed and manufactured in accordance with the conditions listed in the problem to be solved presented by the user.

1. Can be disassembled and assembled

2. Pressure vessel that can keep airtight continuously when shrinkage expansion occurs due to pressure change (0 ~ 400kg / cm2) and temperature change (room temperature ~ 175 ℃)

3. Application of a size suitable for pressures above 400 kg / cm2G and a capacity of 100 cfm (170 m3 / hr), dew point temperature of -63 ° C.

       Periodic exchange of adsorbent is possible, and it maintains constant strength in shrinkage expansion and strength change according to temperature and pressure change, and satisfies related conditions such as 400kg / cm2, 100icfm, -63 ℃ dew point temperature, etc. Applicable to research facilities

Design, fabrication and testing of the required assembly, size of vessel and connecting port according to pressure, flow rate and dew point, and mechanism to maintain airtightness when contracted and expanded according to pressure and temperature changes.

In the drying cycle, the wet air sucked through the suction port of the head passes through the adsorbent filled in the body and is dried.

In the case of the regeneration cycle, the same path is passed, but the difference is that the supplied air is dried air, in which a small amount of 1 to 3% is sucked in, and the band heater is supplied with electric power to heat the torso and the adsorbent. The adsorbent is dried by dry air.

Claims (1)

Size design of pressure vessel suitable for decomposable 400kg / cm2, 100ICFM, dew point temperature -63 ℃ and fabrication of adsorbent using band type heater
