igaraaoa Specification of Letters Patent. Patented Apt. 5, 19211.
Application filed January 17, 1919. Serial No. 27 1,622.'
To all whom mag concern:
Be it known that 1', ROBERT SUczEK, a'c1t1- zen of thenCzechoslovak Republic, residing.
in the city and county of Philadelphia, State 5 of Pennsylvania, have invented certain new and useful Improvements in Condensing -Apparatus, of which the following is 'a.
specification. o
' My vention relates to apparatus for condensmg fluid, as steam, and removing uncondensable flu d, as air, which may be contained in or m assoclatlon w1ththe'condens-.
able fluid before or after condensation.
My invention resides in "condensing appa-' ratus-of any suitable type,,mo-re particularly and the uncondensedfiui cooled by extraction of heat from'the, walls of said passage or passages by cooling medium, as water,
which is p eferably tfwhich' thereafter sure oft e uncondens ed fluid from the ejector, said pum being of; any suitable type,
rahly another ejector. 1
method, reference isto' be ha pany drawing,.in which";
Figure 1, isa side elevationalview of an embodiment of my invention j comprising a to surface condenser with'which is associated multiple stage ejector apparatus with intersta e condensing structure.
g-QZ ispartly an elevation-fiend partly a section, taken on the line 22 of Fig. 1.
. Fi 1 3V is a fragmenta ,elevationalview, part yin-section, on the inc 3-?) of Fi 2. Referring to the drawing, Gis the she I of a surface condenser comprising, in the ex-- ample illustrated, two water conducting tubes (1 and b, extending anks of cooling longitudinally t ereof' and terminating at ich the condensable fluid mm the mixture of the sector is condensed ducting air or uncondensa gases to the ejectors E and E whose sucone end in the cooling water box A and at the other endrin the cooling water box BI The grouping ofthe tubes at and b is with respect to the gartition or diaphragm c in the water box to which coolin water admitted through the intake 01. he water flows through the group of tubes 6 to tlie water box B, thence forwardl compartment of the waterbox A'and thence outwardly through the cooling water outlet e. The fluid to be condensed, as steam from steam turbines,'engines or any other source enters the condenser at D into the dome above the upper tubes (1, flows around and between said tubes into the space between and around the tubes 6 of the lower group, and in so passmg is condensed, the water of-c'ondensatlon-or condensate being received in the hot well G, from which it is withdrawn through the pipe 7 by a suitable pump. 1
The condenser structure as described is one well known in the art, and is given merely as an example of many structures which may be used in a combination embodying my invention.
In this connection it will be understood that my invention is not limited, except where so specified in the claims, toa surface condenser, inasmuch as'some features of my inventionarea plicable with condensers of other types, as or example, jet condensers.
I Communicating with the vacuum space within the condenser is the ipe .g for conhle vapors or tion chambers are'in commumcation with the. pipe 9 through the valves k and k respectively. The ejectors E and E are of any suitable type, preferably and here indicated as of the tubular type, though it will be understood that both oreither may be of v the radial flow type producing disk-shaped into a surrounding difi'user.
otive flui as live or exhaust steam, is furnished the'ejectors E and E through the valves 2' and i pipes and j, and valves is and I4.
Secured to a flange 1 on the water box A, preferably adjacent the cooling water inlet passage d, is a tubesheet or plate m which again. through the group 'of tubes a to t e upper is a wall common to the water box A and the chambers or compartments 72,0, n and rality of tubes g extending forwardly into the water box A adj acent' the cooling water inlet D and extending backwardly to the compartment 0. Similarly, a group of tubes 9 afford communication between the compart- 11 and 0 and are disposed beside the tubes g preferably in like position with respect to the waten box A and the inlet all; The ejectors E and .E discharge, respectively, through the pipes or passages r and 1 into the compartments n and n From the compartments o and 0 extend pipes or passa es s and s to the suctions of pumps P and respectively, which ma be of any suitable type for compressing ei astic fluid, and may be reciprocating, rotary, entrainment, wet or dry or hydraulic air pumps, or any other suitable type of pump; but preferably the pumps P and P are steam actuated ejectors of any suitable type, and may be and preferably are radial flow ejectors producing disk-shaped jets received into surrounding annular diffusers. In fact, the ejectors of each pair, as E and; P, may be, respectively, tubular and radial flow ejectors such as disclosed, for example, in Letters Patent of the 'United States No. 1,282,595, the ejectors P, P receiving their motive fluid through the aforementioned valves i and 11 The ejectorsP- and P have their discharge outlets at t and 15 respectively.
Communicating respectively with the bottoms of the compartments (2 and 0 are the condensate draw-ofi' pipes u and a, controlled by valves v, c and delivering into the pipe w, which delivers into the hot well G or is led to any other suitable destination.
The operation is as follows:
Steam entering at D iscondensed in coming into contact with the cooling water conducting tubes at and b, the condensate passing to the hot well G from which it is withdrawn through pipe f. Uncondensable vapors or air within the condenser are removed, to maintain vacuum therein, by the ejector E whose dischar e is passed through the tubes 9, wherein t e motive fluid or steam for the ejector E or other condensable vapor is condensed, the c ondensate and air being delivered into the chamber 0, and the condensate drawn off through the pipe u while the air is delivered to the second stage pump or ejector'and further raised in pressure. 7
The condensation in the tubes 9 is effected by the cooling water entering at d, before such water has entered the condenser tubes, and therefore before it has effected any con-.
with the said densation and before it has risen in temperature. This will eifect very thorough condensation in the tubes 9 and effect a large fall in temperature of the air and uncondensable vapor, which is accordingly increased in density and more easily operated upon by the, second stage pump or ejector P.
The operation is also the same for the other ejector E and its associated pump or ejector P with their intermediately connected tubes g Communication with either ejector E or E with the interior of the condenser may be discontinued by closing the associated valve h or k. When this is done the other ejector may continue in operation, as when the amount of air to be withdrawn from the condenser is so small as to be readily taken care of by one'ejector or one pair of e'ectors. Or in case of trouble with either pair, that pair may be isolated b closing its associated valve h orit and preferably also by closing the associated valve v or '0 By this structure, involving interstage condenser tubes for each pair of ejectors, each pair is separate and distinct from the other and may be isolated with advantage, as distinguished from the case where the interstage ejector has a condensing chamber common to both pairs of ejectors.
