Description
Technical field
The utility model relates to flooded evaporator technical field, relates in particular a kind of Defrosting structure for flooded evaporator, is particularly suitable for the full liquid evaporimeter of centrifugal cold water source pump.
Background technology
The Chinese invention patent that patent publication No. is CN101194133A, be 2008.06.4 in open day discloses a kind of flooded evaporator, have and form the inner container that accommodates the heat exchange section of heat exchanger, described heat exchanger comprises that internal flow needs cooling medium and realizes heat exchange between the refrigerant liquid that needs cooling medium and the inject described heat exchange section cooling tube with vaporized refrigerant, wherein, from described container, upwards extend to form tubular shell, be provided with described heat exchanger and be communicated with, the inner tube that the refrigerant vapour generating in this heat exchanger is upwards guided, in the top attachment of described inner tube, have and seal and maintain gap described sealing between the top of inner tube, described seal to have to the part of downward-extension and between this downward extension of sealing and described inner tube maintain gap, make upwards to flow and impact described in the refrigerant vapour deflection of sealing downward, in the part of the top of described tubular shell, be provided with demister, to guarantee having for utilizing gravitational effect to make mist landing downwards and the upwards space of the mist of refrigerant of mobile refrigerant vapour of separation described sealing between demister, and the interval area between the described interval area between wherein said downward extension and the described inner tube of sealing downward extension and the inner surface of described tubular shell sealed described in being less than.
But its refrigerant air-liquid separating effect of this patent is poor, in the time of for handpiece Water Chilling Units, the operational efficiency of whole unit is lower.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art part, a kind of Defrosting structure for flooded evaporator is provided, can overcome the deficiencies in the prior art part, it is simple in structure, cheap, relatively good for refrigerant air-liquid separating effect, operational efficiency when can improve handpiece Water Chilling Units.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of Defrosting structure for flooded evaporator, comprise the housing being formed by first member plate, right end plate and cylinder, described housing is provided with feed tube and escape pipe, in described housing, be provided with evaporation tube and be positioned at the demister of described upper part of evaporating, described demister right-hand member is fixedly connected with described cylinder, gapped opening between left end and described first member plate.
Applicant finds after research repeatedly, the vapor-liquid separating structure of existing evaporimeter, it is all the end plate that demister two ends is welded to not perforate, like this, all cold-producing mediums demister of all flowing through, will cause cold-producing medium flow through demister Pressure Drop increase, and affect gas-liquid separation effect, and between the application's structure demister left end and first member plate, be gapped opening, this is distant (generally the exceeding 3 meters) apart from air entry because of clearance opening, even at the air-breathing drop of bringing into of distance so far away, drop 3 meters long with air motion process in also can drop on demister and can not enter gas outlet, such structure, when guaranteeing refrigerant air-liquid separating effect, greatly reduces the cold-producing medium pressure drop of demister of flowing through, thereby improves the operational efficiency of handpiece Water Chilling Units.
As preferably, the length of described clearance opening is the 1/5-1/4 of described drum length.
As preferably, the length of described clearance opening is 1/4 of described drum length.
Its size of clearance opening between demister and first member plate has requirement, and to guarantee that air velocity 2.5m/s-4.5m/s is advisable, if the too small openings of clearance opening, flow velocity is too high, and air-flow can increase through the resistance of demister; As excessive in the opening of clearance opening, flow velocity is too low, and demister area is too small, and drop mobile distance to gas outlet on demister is less, easily causes out gas carrying liquid.
As preferably, described demister right-hand member is fixedly connected with described cylinder by connecting plate, and described demister, connecting plate and described cylinder surround demist cavity.
The size of demist cavity is also conditional, excessive or too small all bad, the cross-sectional area of demist cavity, to guarantee that air velocity 3.5m/s is advisable, the too small meeting of cross-sectional area cause flow velocity excessive and cause stream pressure reduce excessive; Cross-sectional area is excessive, can because of demister distance, to be positioned near liquid level evaporimeter center line closer, can cause that a large amount of drops that seethe with excitement on liquid level are easier to be entered demister with air-flow and cause out gas carrying liquid..
As preferably, described connecting plate is the porous plate that is provided with multiple through holes; The diameter of described through hole is 3-6mm.
As preferably, described multiple through hole cross-sectional area sums account for the 1/3-1/2 of described porous plate cross-sectional area.
In order further to improve gas-liquid separation effect, we are by former imperforate plate, there is the porous plate of through hole instead, the aperture 3-6mm of through hole is good, via count is different and adjust to some extent according to the distance of porous plate and air entry, the actual internal area of general porous accounts for the 1/3-1/2 of the total sectional area of orifice plate, and the too small meeting of actual internal area causes that from demister right side, to enter the refrigerant gas amount of gas outlet very few, causes liquid level in evaporator height inequality; Actual internal area is crossed conference and is caused that from demister right side, to enter the refrigerant gas amount of gas outlet too much, easily causes out gas carrying liquid.
As preferably, described multiple through hole cross-sectional area sums are 1/2 of described porous plate cross-sectional area.
As preferably, described demister is formed by 20-30 layer stainless steel wire net folding, and the thickness of every layer of described stainless steel cloth is greater than 2mm.
As preferably, in described housing, be provided with the liquid-distributing plate that is positioned at described evaporation tube below.
As preferably, described connecting plate and described cylinder and right end plate form split tunnel, and the length of described split tunnel is the 1/30-1/20 of described drum length.
The utility model beneficial effect is:
The utility model is simple in structure, cheap, relatively good for refrigerant air-liquid separating effect, operational efficiency when can improve handpiece Water Chilling Units.
