Abstract
The utility model discloses an anti-scour filter of a water chilling unit, which comprises a flange inner lining, a filter screen and a filter framework used for supporting the filter screen, wherein the filter framework is formed by arranging supporting strips in a surrounding manner, and is connected with the flange inner lining. The anti-scour filter is used in the water inlets of a condenser and an evaporator of a water chilling air-conditioning unit, performs the functions of scouring prevention and impurity filtration, and has the advantages that water flow is prevented from directly scouring the heat exchange tube end of the condenser and the heat exchange tube surface of the evaporator; impurities of large particles can be prevented from entering the water chilling unit; sand and attached sediment also can be filtered during long-term operation; both the disassembly and operation cleaning are convenient.
Description
Technical field
The utility model relates to the air-conditioning auxiliary products, particularly a kind of water chiller erosion control filter.
Background technology
Condenser and the evaporimeter of four large parts of Water cooled air conditioners unit generally adopt copper pipe as heat exchanger tube.General copper pipe used is wall thickness 1.5mm with interior light-wall pipe, easily by welding slag and other bulky grains, is scratched.The special dry evaporator that is the water side for shell side, due to the outer pipe-work connected of unit and carefully filtration cleaning of outer tank, in the evaporimeter leakage accident occurred, because the situation of jam welding slag and stone between heat exchanger tube is very common.And, because condenser generally adopts open circulation, enter in pipe by large granular impurity the situation that causes the Sediment Siltation plugging also very common.The multi-functional glueballs automatic on-line purging system device that the Chinese patent of the patent No.: ZL200920179704.4 is mentioned really can solve the condenser that tube side is the water side or expire the cleaning and filtering problem of liquid unit, but due to the problem that can't reclaim glueballs, on dry evaporator, can't realize, cost has more amplification simultaneously.Therefore be necessary to design a kind of convenient operation, general and with the filter of impingement baffle function.
Summary of the invention
Technical problem to be solved in the utility model just is to provide a kind of water chiller erosion control filter, can solve the impact of washing away of the damage of the water side welding slag of the condenser of current Water cooled air conditioners unit and evaporimeter and other large granular impurities exchange heat pipe and the higher exchange heat pipe of water speed, impurity screening and reduce heat exchanger tube front water speed, extend service life and the heat exchanger Clean after every time of two devices.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of water chiller erosion control filter, comprise that flange liner, screen pack reach for supporting the filter skeleton of screen pack, and described filter skeleton is connected with the flange liner.Filter of the present utility model, for the condenser of Water cooled air conditioners unit and the water inlet of evaporimeter, has the effect of impingement baffle and contaminant filter.
Preferably, described filter skeleton is surrounded by support bar.Support bar can surround cone or cylinder, even can surround first half section cylinder, second half section cone.Support bar can surround the filter skeleton in modes such as horizontal, vertical, oblique or intersections.Because water chiller is connected with the pipe-work of client's machine room, the pipe-work of general refrigeration unit is not strictly carried out the flushing of short circuit water circulation, and the situation that the welding slag in pipeline and impurity pour jam between condenser bobbin carriage and heat exchange pipe of evaporator is very common.During tube bundle vibration, easily cause sharp keen welding slag or impurity and copper pipe extruding to cause the copper pipe breakage.Filter of the present utility model can prevent that oarse-grained impurity from entering unit inside, also can filter the grains of sand and adhere to sediment for a long time in service simultaneously.
Preferably, described support bar comprises longitudinal bracing bar and cross-brace bar, and described longitudinal bracing bar extends to the edge of flange liner from the end of filter skeleton, and described cross-brace bar is coaxial with the flange liner.According to 5.11 regulation in GB151, tube side inlet tube water speed surpasses 3m/s or shell side inlet tube flow velocity surpasses 1.5m/s, import department need arrange impingement baffle, screen pack in filter of the present utility model is nearly pyramid type structure under the supporting role of filter skeleton, current are dispersed by external conical surface through out-of-date, take over axial flow velocity and substantially reduce to zero, reduced current directly washing away condenser heat-exchange pipes end and heat exchange pipe of evaporator surface.
Preferably, described longitudinal bracing bar has 2～10, and every longitudinal bracing bar extends to the different parts at the edge of flange liner.Many longitudinal bracing bars are uniformly distributed, and can make support effect better.
Preferably, described cross-brace bar has 2～10, and every cross-brace bar is distributed in different parts in axial direction.Many cross-brace bars are uniformly distributed, and can make support effect better.
Preferably, the end of filter skeleton is provided with shrouding.Shrouding is solid steel plate, and shrouding, longitudinal bracing bar, cross-brace bar and flange liner surround cylindrical water chiller erosion control filter.Due to cylinder, in water pipe, take up space larger, and impurity is difficult for by Action of Gravity Field, sliding onto in the blow-off line outside the flange liner easily as conical strainer, for the situation that does not need to install temperature-sensing pipe additional and seldom moved online blowdown on water pipe, the erosion control effect is comparatively superior.
Preferably, the end of described filter skeleton to the vertical range of flange liner is 2～3 times of water pipe diameter.Can effectively guarantee that filter effect and mounting or dismounting are convenient.
Preferably, the sealing surface equal diameters of the diameter of described flange liner and water law orchid.Can effectively guarantee that filter effect and mounting or dismounting are convenient.
Preferably, the mesh of screen pack is 20 orders or 50 orders.This structure can for convenience detachly be cleaned with operation, be designed with the tube connector that connects inlet tube by flange before screen pack, bottom design blowoff valve, opening blowoff valve when operation or shutdown can discharge the impurity on filter screen, especially when pipe-work may be dirtier, first adopt 50 purpose fie screens, after pipeline is roughly clean, gain 20 purpose filter screens.Tube connector can be taken out cleaning to filter screen after pulling down.
Preferably, described support bar is flat steel bar.
The utility model provides a kind of water chiller erosion control filter, reduced current directly washing away condenser heat-exchange pipes end and heat exchange pipe of evaporator surface, can prevent that oarse-grained impurity from entering unit inside, also can filter the grains of sand and adhere to sediment for a long time in service simultaneously, for convenience detach and operation is cleaned.
