Abstract
The invention relates to a cooling device for a multi-stage compressor in which two coolers are placed in a common housing. The two coolers cool the medium of the preceiding stage of the multi-stage compressor heated by the input compressor work. The common housing has chambers that are divided into different pressure stages, are connected to the multi-stage compressor by inlet tubes and outlet tubes, and contain water separators with condensate removal pipes associates with them. To be able to conduct the medium to be cooled with a minimum of pressure drops, dividing walls (13,23) are provided at a distance from the top and bottom end, respectively, of the cooling housing (50). Each dividing wall forms a cylindrical space (24,14) with the housing wall (51) and the respective end walls (57,56) of the cooling housing (50) for the installation of the water separators (15,25).
Description
This invention relates to a kind of cooling unit that is used for multistage compressor, this device has been installed two coolers in a total housing, these two cooler coolings are compressed the prime medium of merit heating, this housing also has the chamber of several different pressures simultaneously, above-mentioned chamber links to each other with compressor with steam outlet pipe by air inlet, in the chamber in addition with the separator of condensate discharge pipe.
As cooler, often manufacturing the bottom surface when with water cooling is circular obround vessel, loads onto the cooling element of parallel to an axis in this container.Cooling water flow supercooling element, the parallel installation of separator with cooling element, medium to be cooled is by guide vane guiding (US-PS3,835918).
The most essential shortcoming of this known cooler be particularly when the installation of separator is parallel to cooling element medium to be cooled in cooler, turn to often.
Task of the present invention provides a kind of cooling unit identical with the above-mentioned type, make pressure medium loss to be cooled minimum, and cooling effect is identical.
Technical solution of the present invention is: the dividing plate perpendicular to housing shaft is installed in the front end of shrinking away from theshell body or a distance, rear end, the end wall of these dividing plates and shell body wall and housing has constituted the cylindrical cavity that can hold separator, dividing plate all has a breach, gas is flowed out by cooling element, enters in the cylindrical cavity by this breach.
In further technical solution of the present invention:
At the upper area of shell body wall, steam outlet pipe is installed in the cylindrical cavity.
Separator flatly is installed in the cylindrical cavity.
The dividing plate that a end respect to one another with shell body wall and vertical partition plate joins has been installed, this dividing plate basically with the central axes of housing.
It is directly plane that parallel baffle is in the cooling element zone, and the zone beyond this has at least an end to be spiral form.
The spiral form part of parallel baffle is made up of three straight planes at least.
Independent cavity forms the part that this cavity is positioned at the cooling element first half by the surface of the spiral form of dividing plate part, vertical partition plate and cooling element and constantly dwindles towards the direction of the cylindrical cavity that pressure is arranged.
Major part in the shell body wall upper cavity is equipped with suction tude.
Coolant intake pipe and coolant outlet hose are installed on cooling element.The axis of these pipes and the central axes of housing, and by cavity with pass end wall.
Also can make the cavity of the cooler of one cooling water input and output pipe by its place in two cooling elements.
Dispose seal element between the outer wall of cooling element and vertical partition plate, the sealing element separates the pressure chamber with the cavity that cooling water input, output tube are housed.
Because separator is installed in the space that the cooling element chamber is separated, medium to be cooled so not only vertically passes through separator, and no longer vertically passes through cooling element through aforesaid turning to, and therefore medium to be cooled only turns to twice.
Some spaces that are used for separator can utilize the whole diameter of housing, therefore allow separator that suitable size is arranged, and so just can use the whole inner chamber of circular cylindrical cavity, and separator is installed one by one in circular cylindrical cavity.
Water-cooling tube extends by each stage pressure cavity and along separator.A kind of structure of preferential employing is to make whole cooling waters be carried into by a side of cooling unit, and the cavity of each cooler and the sealing of the cavity of another cooler separate, their pressure is also different, particularly cooling element is mounted in the time of can pushing or extract out, this structure can be changed element easily.
An embodiment of this invention as shown in drawings, wherein:
Fig. 1 is the schematic representation of compressor apparatus.
Fig. 2 is a kind of cooler axonometric drawing of two chambers, the figure shows the internal structure of cooler.
