Description
CONDENSATE SEPARATOR
This invention relates to an improved condensate separator which is generally fitted downstream from a heat exchanger in industrial installations.
A condensate separator normally known comprises a container housing a filtering device (demister) formed from metal filaments, which is crossed by the flow of cooled gas, saturated with moisture. The gas strikes the filter frontally and the microdrops of water in suspension, hitting the said filter's filaments, grow in size because of aggregation with other drops which undergo the same process. Once a mass has been reached such that the drops of water can no longer be entrained by the gas flow, they fall due to gravity and are then removed through a drain. Naturally, during operation of the condensate separator, the filter is subject to fouling, as it holds on to the impurities contained in the gas which passes through it.
A first technical problem which this invention is intended to face and solve is that of separation of the condensate which forms after the cooling of a wet gas at a temperature lower than the dew point at working pressure. In addition, a further problem to be solved is that of carrying out maintenance and cleaning of the condensate separator without having to remove the whole separator from the installation to which it is fitted. This operation is, in fact, laborious and complicated and requires stoppage of the installation for a considerable time, with the economic cost concerned.
The object of this invention is to propose a condensate separator improved to increase its operating efficiency and to simplif' the maintenance and cleaning
I
* operations, making it possible for these to be carried out without the need to remove the whole separator from the installation.
This object is achieved with a condensate separator which is made as stated in the claims. In particular the invention provides a condensate separator for wet gas, in particular to be used downstream from a heat exchanger, substantially comprising a container closed at one end and open at the opposite end which is provided with a flange for connection to the duct for outlet of the gas saturated with moisture; the container internally houses a filtering device and is provided with a dried gas outlet duct and a condensate drain, characterized in that the closed end of the container is equipped with a removable end plate and the filtering device is supported by means of a mechanism with which it is possible to keep it in position inside the container and to extract it therefrom.
The invention will be further described, on an exemp1iing and non-limiting basis, with reference to the attached drawings, where Figure 1 shows, in schematic section, a condensate separator according to an embodiment of the invention and -Figure 2 shows, in perspective, a part of the condensate separator of Figure 1.
In this embodiment the condensate separator comprises (Figure 1) a hollow cylindrical body or container 10 which is provided, at one end 12, with a flange 14, capable of sliding with respect to the centre-line of the body 10, in order to connect the separator to the inlet duct (not shown) for the cooled wet gas coming out of a heat exchanger of an industrial installation. At the opposite end 16, the body 10 is provided * with a loose flange 18, on which is mounted an end plate 20 suitable for closing, with the interposition of a protection disc 22, the end 16 of the said body.
The condensate separator body 10 is also provided, close to the end plate 20, with a duct 24 for the outlet of the gas after dehumidification and with a drain 26 for the condensate.
The body 10 houses a filtering device (demister) comprising two filters 28, 30 in series with each other, arranged at right angles to the centre-line of the body and therefore to the direction of the flow of gas to be dehumidified. Each filter is in the form of a cylinder, the bases and side surfaces of which are made with thin wires, interlaced to form a mesh. The distance between the two filters is calculated depending on the their housing diameter, so that, at the outlet from the first filter 28, the drops of water in parabolic motion impact approximately at the same height on the second filter 30. Inside the latter, the drops of water continue to grow in size and weight to precipitate on the bottom of the separator, immediately downstream from the second filter or after being entrained by the current of gas for a short way.
The distance between the second filter 30 and the dehumidified air outlet duct 24 is calculated depending on the diameter of the body 10, it being considered that any acceleration of the gas flow close to the duct 24 could cause entrainment of condensate which would reduce the separator efficiency. Acceleration of the gas flow can be caused by the fact that the section of the gas outlet duct 24 is slightly smaller than the section of the opening in the body 10 to which the duct 24 is connected.
The filters 28, 30 are mounted on an extraction and stabilization mechanism (Figure 2), comprising a rod 32 which passes through the filters, substantially coaxial with the centre-line of the body 10 and a handle 34 for moving the filters as a unit. The handle 34 is fastened to the end of the rod 32 which reaches close to the end plate 20 of the body 10. The bases of each filter are provided with a pair of stabilization bars 36, 38; the first bar is welded to the rod 32, whereas the second one keeps the filter at right angles to the centre-line of the body 10 at the stage of the filter being introduced into the body. In fact, the diameter of the filters is slightly greater than that of the body 10, so as to carry out forced insertion of the filters in the said body to ensure the adhesion of the filters to the internal wall of the body 10 and, thus, to prevent part of the gas flow from being able to pass along the internal wall of the body 10.
To ensure that the distance between the two filters remains unchanged after each separator maintenance and/or cleaning operation, it is also provided that at least one spacer 40, arranged on the rod 32 between the two filters, is used.
Therefore, with the condensate separator as described, it is possible to carry out the marntenance and cleaning operations simply by removing the end plate 20 from the body 10 and extracting, by means of the handle 34, the filters 28, 30 fitted to the rod 32.
The object of preventing the need to remove the condensate separator from the installation completely is therefore achieved in full.
