AMMONIA CONDENSER.

Application filed January 4, 1927.

My invention relates to lll'lPIOVGHlGIltS in ammonia condensers, and it conslsts 1n the combinations, constructions, and arrangements, hereinafter described and claimed.

An object of my invention is to provide an ammonia condenser which causes the gases to flow from a common header through a pluiality of pipes connected with the header, and which has means for cooling the pipes with water, the water being directed over each pipe by baffles whereby the pipes are effectually cooled.

A further object of my invention is to provide a device of the type described in which air is passed over the pipes and through the water for cooling the pipes and the water.

A further objectof my invention is to provide a device of the type described in which the pipes are provided with stops for causing the liquid ammonia to flow in one direction through the pipes.

Other objects and advantages will appear in the following specifications and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application in which Figure 1 is a side elevation of the device,

Figure 2 is a section along the line 2-2 of Figure 1,

Figure 3 is a side elevation of the device with the casing removed,

Figure 4 is a section along the line 4-4: of Figure 5,

' Figure 5 is an enlarged detailed view of a portion of the device,

Figure 6 is a section through one of the pipes, and

Figure 7 is a view of a partition used in the device.

In carrying out my invention, I provide a catch basin 1 to which an outlet pipe 2 is con nected, the pipe 2 in turn being connected to a pump 3. A pipe 4 leads from the pump 3 to a plurality of outlet nozzles 5. The nozzles 5 are disposed above a condenser now to be described.

The condenser comprises two vertical headers 6 and 7, which communicate with horizontal headers 8 and 9. respectively. A plurality of pipes 10 connect the headers 6 and 7 together. An inlet pipe 11 communicates with the header 8 while an outlet pipe 12 communicates with the header 9. It will be noted from Figure 3 that the header 8 is disposed above Serial No. 159,011.

the header 9 and that a pipe 13 connects the headers together for a purpose hereinafter described.

A casing 1 1 encloses the condenser and is formed with a plurality of partitions 15, sidewall section 16 and top section 17 The partitions are formed in two parts, each part having sen'ii-circular recesses 18 therein for receiving the pipes 10 and inclined grooves 19 therein for receiving baflles 20, as clearly shown in Figure 7.

The partitions 15 carry lugs 21 to which the side sections 16 and the top sections 17 are bolted. The headers 6 and 7 also carry lugs 22 for supporting certain 01 the sections 16 and 17. I

It will be noted from Figure 2 that the easing 14.- is open at its lower end and has an air pipe 23 communicating with the top thereof. This pipe connects with an air pump 24 which sucks the air up through the interior of the casing 1 1, the air passing over pipes 10 and the baffles thus effectually cooling the water and the pipes.

In Figure 6 I show the pipe 10 as being provided with a stop 24, disposed adjacent to the header 6. This stop prevents the liquid ammonia from flowing into the header 6 an causes it to flow into the header 7.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood; The ammonia in a gaseous state flows from the pipe 11 into the headers 8 and 6 and then through the pipes 10. The ammonia is changed into a liquid state as it passes through the pipes 10 and is then conveyed to the headers 7and 9 and out through the pipe 12. As heretofore described the stops 24 in the pipes 10 cause the ammonia liquid to flow into the header 7 instead of into the header 6.

In case any of the ammonia condenses in the header 6 and falls into the header 8, this liquid ammonia may be conveyed to the header 9 by means of the pipe 13. A valve 25 controls the flow of: liquid in the pipe 13.

It will also be noted in Figure 3 that I provide oil pipes 26 and 27 comn'iunicating with the headers 8 and 9 respectively. These pipes are for the purpose of draining off any oil which might collect in the bottom of the headers 8 and 9. The partitions 15 confine the water delivered from each nozzle 5 to a certain area of the pipes 10. The baflies 20 cause this water to flow over the pipes 10 in a film which hugs the pipes. As heretofore stated the air is sucked through the casing 1% by means of the pump 9A, and cools the water and the pipes.

The mixture of the air with the ammonia gases produces a certain amount of non-eondensihle which has a tendency to build up sutlicient pressure in the piping system of the condenser to prevent the flow of the ammonia gases therethru. In order to main tain the ammonia flow thru the pipe the noncondensihle gases, that are lighter than the ammonia gas, rise in the header 7 into chamber 28, which is so designed that a plurality of headers may be connected thereto. The non-coinilensihle gases then rise into the container 29 and may he passed oli thru a valve 30. There may be some non-condensihle gas produced in the ammonia which is heavier than the ammonia gas, or the condensate, and these gases will flow with the condensate and may be tapped after passing thru the header 9. It will be recognized that with the aid of the container 29 and valve 30 and the header 9, the piping system of the condenser is always kept clear of any non-condensihle gas that tends to clog the passage of the ammonia gases therethru.

I claim:

1; A device of the type described, comprising a plurality of pipes, means for conveying water to said pipes, battles for causing the water to flow in a film over each pipe and to hug the pipes, and means tor drawing air past said pipes and through the water.

2. A device of the type described, comprising a horizontal header, a second header mounted at a lower level than the first header, condenser means connecting said headers together, and a pipe for connecting said headers together for conveying any liquid from the higher header to the lower header.

3. A device of the type described, comprising a horizontal header, a second header mounted at a lower level than the first header, condenser means connecting said headers together, and a pipe connecting said headers together for conveying any liquid from the higher header to the lower header, and an oil conveying pipe communicating with the bottom ct said headers.

a. In a device of the type described, condenser, a sectional casing disposed around said condenser, said casing providing an inlet and an outlet for air, and eon'lprising partitions, means carried by said partitions for removably supporting battle plates, hail e plates secured to said partitions, and wall and top sections secured to said partitions.

In testimony whereof I atiix my signature.
