Description
Technical field
The utility model relates to the automatic gas extraction device of incoagulable gas; This device is through compiling incoagulable gas automatically; Realize under the condition of few rate of air sucked in required, can effectively get rid of the thin incoagulable gas of content, belong to the lithium bromide absorbing type refrigeration apparatus technology.
Background technology
Lithium-bromide absorption-type refrigerating machine be with water be cold-producing medium, lithium-bromide solution be absorbent refrigeration plant.In the evaporimeter of equipment, aqueous water under low pressure evaporates heat absorption, becomes water vapour, and the absorber of water vapour access arrangement is absorbed by bromize lithium concentrated solution, has kept the low pressure of evaporimeter, makes water can continue the evaporation heat absorption, so keeps kind of refrigeration cycle.Water is 102kPa at the saturation pressure in 100 ℃ of whens boiling, and saturation pressure at low temperatures is very low, and for example: in the time of producing 7 ℃ cold water, the evaporating temperature of unit is necessary≤5 ℃, and water is merely 0.87kPa at 5 ℃ saturation pressure.So lithium bromide absorbing type refrigeration is a kind of refrigeration plant of work under high vacuum state, the quality of vacuum state directly influences the performance and the life-span of unit.How guaranteeing the high vacuum degree of unit, is one of important indicator of weighing lithium-bromide absorption-type refrigerating machine quality height.
Because lithium-bromide solution has stronger corrosivity to steel containing under the oxygen condition, and in corrosion process, produces hydrogen; Simultaneously, when equipment injects lithium-bromide solution, because the solution gas in the lithium-bromide solution also can be brought incoagulable gas into; The leakage of body also can get into incoagulable gas.So the lithium-bromide absorption-type refrigerating machine group in running, always has incoagulable gas and produces, must at any time incoagulable gas be discharged, keep needed condition of high vacuum degree.In order to get rid of the incoagulable gas in the body, automatic gas extraction device is set usually.A kind of employing solution injection principle is for example arranged, and the negative pressure that forms during high flow rate when utilizing solution to pass through nozzle is taken away the incoagulable gas in the body, and discharges outside the body through vavuum pump.
Because the unit intracorporeal space is too big, incoagulable gas content is thin, and almost is distributed in uniformly in the body everywhere, or moves to the lower position of body internal pressure.And the rate of air sucked in required of automatic gas extraction device is very little, how to arrange suction location and the air entry form of automatic gas extraction device in body, utilizes the limited inspiratory capacity of automatic gas extraction device, discharges incoagulable gas to greatest extent, is a difficult problem.It will directly influence the effect of keeping of unit vacuum, influence the operational effect and the life-span of unit.
At present, the automatic pumping system of lithium-bromide absorption-type refrigerating machine does not generally have gas collecting apparatus, mainly adopts the mode of exhaust tube directly to bleed.Fig. 1 is a kind of signal of the structure of typically directly bleeding.Exhaust tube is arranged in centre position in absorber bottom, and the exhaust tube bottom offers aperture, and opening down.
Because incoagulable gas always comes together in the pressure lowest part; During unit work; Refrigerant vapour is always flowed to absorber by evaporimeter, and the position that then the unit internal pressure is lower should be positioned at absorber, and should be positioned at the position that absorber solution content is higher, cooling water temperature is lower.But common unit flow scheme design mode is the cooling water low in and high out, and concentrated solution is high in and low out.Therefore, no tangible low-pressure area in the unit in fact, or think that the longest position of water vapour flow process is the pressure minimum point.So, usually the air entry of automatic gas extraction device is arranged in the centre position of absorber bottom, as shown in Figure 1.But the low pressure in fact here is not really tangible, only is to judge by rule of thumb.Simultaneously; Even there is relatively low pressure here, its pressure reduction also is quite faint, and the incoagulable gas here and steam coexist; Water vapour content is much larger than the composition of incoagulable gas; Under the condition of the limited rate of air sucked in required of automatic gas extraction device, the ability of getting rid of incoagulable gas is very faint, and the effect of automatic gas extraction device also will be very limited.
If the effect of bleeding of automatic gas extraction device is bad, along with the increase of incoagulable gas content, the efficient of unit will significantly reduce, and refrigerating capacity reduces, and the corrosion of unit is accelerated, and the life-span reduces.
The utility model content
The utility model technical problem to be solved be on the above-mentioned basis that is used for automatic gas extraction device, provide a kind of ability of getting rid of incoagulable gas better, more stable structure setting.
For solving the problems of the technologies described above; The utility model has been done further improvement to the structure of incoagulable gas automatic gas extraction device: the special pneumatic trough that is provided with incoagulable gas of installing in the absorber of bromine cooling machine; Pneumatic trough is the groove shape body that a thin plate is processed; Two ends are connected with the tube sheet at absorber two ends, about seal continuously with the top, have only lower opening.Be installed in absorber inner opening pneumatic trough down, arrange cooling tube in the pneumatic trough, these cooling tubes also belong to the part of whole absorber cooling tube.The cooling water that flows in the cooling tube, the cooling tube spray bromize lithium concentrated solution that distributes outward because the cooling of cooling tube, makes in the groove bromize lithium concentrated solution keep relative low temperature, possesses stronger water imbibition, forms lower absorption pressure district.Because the existence in local depression district; Make of the bottom entering of the mist of a large amount of water vapours and incoagulable gas from pneumatic trough; This mist gets in the flow process behind the pneumatic trough; Steam is constantly absorbed by bromize lithium concentrated solution, and remaining incoagulable gas is because inertial flow and continue mixed gas and sweep along promotion travels up to the top of pneumatic trough.Therefore, the concentration of the incoagulable gas at pneumatic trough top is the highest, and the pneumatic trough top the highest in incoagulable gas concentration is provided with bleeding point, connects exhaust tube, extracts incoagulable gas out, and the eliminating efficient of incoagulable gas is significantly improved.
This pneumatic trough can be arranged at the lower centre position of absorber chamber pressure usually, but because the cooling tube of good cooling results has been arranged in the pneumatic trough of the utility model, possesses getter action.So according to the lithium bromide refrigerating unit of different structure, pneumatic trough is installed in other any positions, can accomplish gas collection work smoothly in the same old way.
The pneumatic trough of the utility model is inboard again bleed the mouth of pipe can be directly in the pneumatic trough open top as bleeding point, also can exhaust tube be set in the pneumatic trough inside top, on exhaust tube, open a plurality of bleeding points, such effect can be better.
