Abstract
The utility model provides a hydraulic filling evaporator demisting structure for a centrifugal type unit. The hydraulic filling evaporator demisting structure is composed of a shell, a heat exchange pipe bundle and an air suction opening. A mesh demister is arranged above the heat exchange pipe bundle and composed of stainless steel wires. The two sides of the mesh demister are provided with mesh demister end plates, and the periphery of the mesh demister, the periphery of the mesh demister end plates and the periphery of the shell are welded in a sealed mode. An air suction baffle is arranged above the mesh demister, the two sides of the air suction baffle are provided with air suction baffle end plates, and the air suction baffle, the air suction baffle end plates and the shell are welded in a sealed mode. A plurality of long strip holes are formed in the edge wherein the air suction baffle and the shell are welded. Through double demisting and filtering of the mesh demister and the air suction baffle, fine liquid drops in gaseous refrigerant can be effectively eliminated, damage on a compressor due to the fact that liquid exists in air suction is avoided, the cooling capacity of the unit is improved, the energy efficiency ratio of the unit is increased, the compressor can be effectively protected, and operation of the unit is more reliable.
Description
Technical field
The utility model relates to a kind of central air-conditioning centrifugal chiller evaporimeter demister.
Technical background
Along with continuing of building of Chinese national economy, fast-developing, living standards of the people improve fast, the demand of large standard ton refrigeration air-conditioner is increasing, and centrifugal unit has been subject to numerous clients' favorable comment with its large cold, low noise, high energy efficiency and the advantage such as reliable.
Evaporimeter is requisite parts in centrifugal unit, liquid refrigerant from flash tank enters evaporimeter through reducing pressure by regulating flow, the heat of absorption refrigerating water in evaporimeter and evaporating, become gaseous refrigerant, the air entry that gaseous refrigerant enters compressor is compressed by compressor, carries out the circular work of a new round.
Due to centrifuge, in the pressure of inspiration(Pi) compression process, do not allow absorbing gas belt liquid, cold-producing medium absorbs heat and becomes gaseous state in evaporimeter, and due to the existence of compressor lubricant oil, lubricating oil is understood some and is entered in evaporimeter with cold-producing medium, under cold-producing medium heat absorption evaporation fluidized state, lubricating oil can form small drop with cold-producing medium, under compressor air suction mouth suction, enters compressor.But centrifugal compressor does not allow the generation of absorbing gas belt liquid phenomenon, if above-mentioned condition occurs, not only can reduce the cold of unit, also compressor is caused to major injury.
Summary of the invention
The purpose of this utility model is to provide the Defrosting structure of a kind of centrifugal unit with flooded evaporator, to solve the problems of the technologies described above.
The utility model mainly is comprised of housing, heat-exchanging tube bundle, air entry, the technical scheme that solves its problem is that the top of heat-exchanging tube bundle arranges mesh mist eliminator, mesh mist eliminator is made by stainless steel cloth, the mesh mist eliminator both sides arrange the mesh mist eliminator end plate, mesh mist eliminator, mesh mist eliminator end plate and the welding of housing peripheral sealing; The top of mesh mist eliminator arranges air-breathing baffle plate, and air-breathing baffle plate both sides arrange air-breathing baffle plate end plate, air-breathing baffle plate, air-breathing baffle plate end plate and housing seal welding, and the edge of air-breathing baffle plate and housing welding is provided with the many places strip hole.
Preferably, the 100mm of the close air entry of air-breathing baffle plate is with interior not perforate.
The good effect that adopts this structure is to filter through the dual demist of mesh mist eliminator and air-breathing baffle plate; can effectively eliminate the fine droplet of carrying secretly in gaseous refrigerant; avoid the damage of absorbing gas belt liquid to compressor; improve the cold of unit; increase the Energy Efficiency Ratio of unit; and can effectively protect compressor, make the operation of unit more reliable.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model, and in figure: 1 is tube sheet, and 2 is the mesh mist eliminator end plate, and 3 is air-breathing baffle plate end plate, and 4 is air-breathing baffle plate, and 5 is mesh mist eliminator, and 6 is air entry, and 7 is housing, and 8 is heat-exchanging tube bundle.
The specific embodiment
As shown in Figure 1: mesh mist eliminator 5 is made by stainless steel cloth, and mesh mist eliminator 5 is positioned at directly over heat-exchanging tube bundle 8, mesh mist eliminator 5 and mesh mist eliminator end plate 2 and housing 7 peripheral sealing welding; Air-breathing baffle plate 4 is positioned at the top with mesh mist eliminator 5, is placed under air entry 6; Air-breathing baffle plate 4 and air-breathing baffle plate end plate 3 and housing 7 seal weldings, air-breathing baffle plate 4 is provided with the many places strip hole with the edge of housing welding.Air-breathing baffle plate is better with interior not perforate effect near the 100mm of air entry.
During use, liquid refrigerant (containing a small amount of gas) from flash tank enters evaporimeter from the evaporimeter bottom, after absorbing tube side circulating water heating amount, explosive evaporation, become saturated gas, above heat-exchanging tube bundle 8, assemble, because gas in the explosive evaporation process rises, be entrained with small drop, gas separates through mesh mist eliminator 5 fine droplet of carrying secretly in gas; Through air-breathing baffle plate 4, the gas break-in is clashed into again, the fine droplet of carrying secretly in gas can further separate, and separating effect is higher; Last gas enters compressor through air entry 6.
Claims (2)
1. a centrifugal unit use expires liquid evaporimeter Defrosting structure, mainly by housing, heat-exchanging tube bundle, air entry, formed, the top that it is characterized in that heat-exchanging tube bundle arranges mesh mist eliminator, mesh mist eliminator is made by stainless steel cloth, the mesh mist eliminator both sides arrange the mesh mist eliminator end plate, mesh mist eliminator, mesh mist eliminator end plate and the welding of housing peripheral sealing; The top of mesh mist eliminator arranges air-breathing baffle plate, and air-breathing baffle plate both sides arrange air-breathing baffle plate end plate, air-breathing baffle plate, air-breathing baffle plate end plate and housing seal welding, and the edge of air-breathing baffle plate and housing welding is provided with the many places strip hole.
2. novel centrifugal type unit according to claim 1, with full liquid evaporimeter Defrosting structure, is characterized in that the 100mm of the close air entry of air-breathing baffle plate is with interior not perforate.
