Description
Technical field
The utility model relates to a kind of lithium bromide refrigerator working medium purifying processing device, particularly a kind of lithium-bromide absorption-type refrigerating machine vacuum sewerage purifier.
Background technology
Lithium-bromide solution is the working medium of lithium-bromide absorption-type refrigerating machine, and the main material of lithium-bromide absorption-type refrigerating machine is carbon steel and red copper.Because unit moves under vacuum state, working medium fully contacts down at high temperature (40 ℃-165 ℃) with metal material, chemical reaction takes place, after peeling off, the oxide that is generated enters in the working medium, and remain in a small amount of welding slag in the machine in the processing and making process, metal fillings and also can circulate with working medium because of adding cotton-shaped suspension that octanol produces etc., so when flowing through the very little nozzle of passage, when drenching plate hole, not only can produce obstruction, and, during through canned motor pump pump also there is damage, then can make the working medium disequilibrium, blackout is rotten gradually, causes that refrigerating capacity descends, when serious complete machine is scrapped, therefore, remain the cleaning of working medium, to the performance and life-span of lithium-bromide absorption-type refrigerating machine all be vital.For solving purifying problem, normally adopt the processing of regularly method outside the working medium shedder being regenerated.Because about 2000 yuan/ton of its disposal cost of this method, and the loss of 15-20% is arranged, must supply new soln according to quantity after the regeneration, and the new soln price is about 20000 yuan/ton in addition, therefore, the regeneration expense of solution is very high.At present; also have and adopt the way that installs purifier additional to handle; but because the purifier that adopted is to be installed in plain filter on the refrigeration machine pipeline or accurate piping filter etc. with series system mostly; though they can overcome the deficiency of said method to a certain extent; foreign material are carried out filtering; but, must under stopped status, abolish vacuum and after outside the solution shedder, can carry out if need blowdown.
The utility model content
The utility model is the deficiency that exists in the above-mentioned background technology; provide a kind of can not only effectively filtering working medium in foreign material; and; need not shut down and to finish blowdown, device maintenance and part replacement work, and can reduce the lithium-bromide absorption-type refrigerating machine vacuum sewerage purifier of operating cost greatly.
Its concrete solution is: the purifier body is made of urceolus and the filter that is arranged in the urceolus, and, the control valve that urceolus is provided with the feed tube that can be connected with the refrigeration machine distribution drum and is used to control solution and suction and pump drainage air in the emission-control equipment body.The bottom of urceolus is provided with blowdown control mouth, and the drain pipe that can be connected with the refrigeration machine heat exchanger links to each other with filter, and, be respectively arranged with control valve on feed tube and the drain pipe.
In addition then, be used to control that the control valve of solution and suction and pump drainage air is the vacuum diaphragm valve in the emission-control equipment body.And the control valve that is provided with on feed tube and the drain pipe is a vacuum butterfly valve.
Moreover, be respectively arranged with the active joint of being convenient to dismantle the purifier body on feed tube and the drain pipe.
Simultaneously, described filter is to be made of filter cylinder frame and the filter screen that is arranged on the filter cylinder frame.
The utility model can be installed in it between solution distribution drum below and the heat exchanger with bypass mode by feed tube and drain pipe, when refrigeration machine is worked, make the working medium that has impurity in feed tube input urceolus, and be delivered in the heat exchanger by the working medium of drain pipe cleaning through the back that filters out impurities of the filter screen on the filter.And when blowdown is handled, can make the work circuit cycle of working medium by handling the vacuum diaphragm valve by former refrigeration machine.It is not only simple in structure, good purification, and, need not shut down during blowdown, air can not enter unit, can not influence unit performance and change the unit cooling condition.Owing to can at any time dirt be removed as required and when removing dirt, also can clear up and change filter screen simultaneously, make it can remain good strainability, stop dirt and rest on the chance that reacts with working medium in the refrigeration machine, thereby effectively prevent to decay because of the rotten unit performance that causes of lithium-bromide solution.Simultaneously, thoroughly, both reduced energy consumption, reduced operating cost again for the user has saved working medium regeneration work of treatment and higher correlative charges.

The specific embodiment
Among Fig. 1, Fig. 2, Fig. 3, urceolus 3 is connected with cylindrical shell and is made of the loam cake 11 that sealing ring 10 seals by cylindrical shell and by bolt 9.Be arranged in the urceolus 3 and the filters that are connected with loam cake 11 are a filter cylinder, 400 order stainless steel filtering nets 5 constituted at the bottom of it was sleeved on double tubular band on the filter cylinder frame 4 by filter cylinder frame 4 and by snap ring 7.The bottom of urceolus 3 is provided with blowdown control mouth 6, and bottom one side of urceolus 3 is provided with vacuum diaphragm control valve 8.Two control valves 1,13 are vacuum butterfly valve, and they are separately positioned on the feed tube 15 that links to each other with urceolus 3 and reach on the drain pipe 14 that is connected with filter cylinder by loam cake 11, simultaneously, are respectively arranged with active joint 2,12 on feed tube 15 and the drain pipe 14.
When use installing, as shown in Figure 4, this device is installed between solution distribution drum 18 belows of refrigeration machine and the heat exchanger 16 with bypass mode gets final product.Under the duty, vacuum pipe valve 17 in the refrigeration machine should cut out, and simultaneously the import and export vacuum butterfly valve of this device is opened, working medium solid arrow direction in the Fig. 4 of lower edge of carrying impurity at first enters urceolus 3 through control valve 1, and after filter screen 5 enters in the filter cylinder after filtering, the purification working medium in its filter cylinder will enter in the heat exchanger 16 of refrigeration machine through drain pipe 14.And will being blocked on filter screen, the impurity in the working medium waits for discharging outward.
During simple blowdown, control valve 1,13 is closed, simultaneously, open the vacuum pipe valve 17 in the former loop of refrigeration machine, make working medium by the former circuit cycle of the refrigeration shown in the dotted arrow among Fig. 4, then, open the control valve 8 in this device, make the air access to plant, and the solution in the discharge device.Capable blowdown is filled in blowdown on the blowdown of the outwarding winding control mouth 6, simultaneously, and also available clear water flushing.Blowdown screws the blowdown plug after finishing, and connects flexible pipe to vavuum pump by control valve 8, after opening the air in the vavuum pump withdrawing device, closed control valve 8 is opened control valve 1,13, close the vacuum pipe valve 17 in the former loop of refrigeration machine simultaneously, device recovers to filter duty again.
Thoroughly during blowdown, can make working medium by the former circuit cycle of the refrigeration machine shown in the dotted arrow among Fig. 4 according to the operation of above-mentioned simple blowdown, and the solution in the discharge device, then, unload this device back by active joint and the purifier body is thoroughly cleared up or the part that damages is changed.
