Problems solved by technology

[0003] In the refrigeration process of the dry evaporator, the currently commonly used liquid separation still has the following defects: 1) Due to the uneven liquid separation of the gas-liquid refrigerant mixture in the dry evaporator in the first process of the split tube box, The vaporization process of the gas-liquid refrigerant after heat exchange is insufficient, resulting in a decrease in heat transfer performance; 2) The existing baffles with small holes are installed in the split-range tube box or the form of welding capillary tubes and evaporator tube bundles is adopted , these liquid separators have complex structures, high sealing requirements, and difficult processing, resulting in high processing costs, uneconomical, and energy-saving

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0014] This embodiment is a dry-type evaporator liquid distribution and uniform distribution device used in the process of refrigeration and air conditioning. It is composed of a liquid distribution uniform distribution device 4 and associated tube sheets 1 and evaporator tube bundles 2. The liquid separation Distributor 4 is an upper, smaller, lower, and large circular platform with a basin-shaped conical hole and a connected cylindrical hole inside the axial section. The height of the cone is 12mm, the outer diameter of the small end of the cone is φ12.3mm, and the cone angle of the cone is 2.5°; the taper angle of the basin-shaped conical hole is 15°, the diameter of the cylindrical hole is φ4mm, and the depth is 4mm. figure 1 , 2 The given structure is installed, wherein: insert the small end of the liquid distributor 4 into the first process of the split tub...

Abstract

The invention relates to a device for uniformly distributing a liquid by using a dry evaporator and a use method thereof. The problems of complex structure, high sealing requirement and high processing difficulty exist in the conventional liquid distribution device. In a technical scheme of the invention, a gas-liquid refrigerant mixture is distributed more uniformly by using the uniform liquid distribution device in the dry evaporator. The device consists of a uniform liquid distributor, a correlated tube plate and a steam-generating bank. The device has the beneficial effects that: a conical cylindrical uniform liquid distributor is directly arranged in the tube orifice of the steam-generating bank, heat exchange is performed by fully utilizing all steam-generating banks, and energy efficiency is increased by 15-20 percent in comparison to the conventional liquid distribution device. The device is an energy-saving device which has a compact structure and low processing cost and is convenient to manufacture and install.

Description

technical field [0001] The invention relates to a liquid distributing device in an evaporator, in particular to a liquid distributing and evenly distributing device for a dry evaporator and a use method thereof. Background technique [0002] Refrigeration and air conditioning are widely used in daily life. The shell-and-tube dry evaporator is the main part of the refrigeration system. It is composed of a cylinder, tube sheets at both ends, split-range tube boxes, evaporation tube bundles, baffles, supports and corresponding connecting pipes. Among them, the split-range tubes Whether the liquid separation in the box is evenly distributed will directly affect the performance of the dry evaporator and the utilization rate of the evaporating tube bundle. [0003] In the refrigeration process of the dry evaporator, the currently commonly used liquid separation still has the following defects: 1) Because the liquid separation of the gas-liquid refrigerant mixture in the dry evapo...
