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
The present invention relates to a kind of liquid distributing device in evaporimeter, particularly relate to a kind of dry evaporator separatory even distribution device and method for using.
Background technology
Refrigeration air-conditioner is widely used in daily life.The shell-and-tube dry evaporator is the critical piece in the refrigeration system; It is made up of cylinder, two ends tube sheet, branch journey bobbin carriage, steam-generating bank, deflection plate, bearing and corresponding the adapter, and wherein whether the separatory in the branch journey bobbin carriage is uniformly distributed with the utilization rate with performance that directly has influence on dry evaporator and steam-generating bank.
In the dry evaporator process of refrigerastion; Usually the separatory that adopts at present remains the defective aspect following: 1) owing to the separatory of gas-liquid refrigerant mixture in minute journey bobbin carriage first pass in the dry evaporator is inhomogeneous; Make the gas-liquid cold-producing medium insufficient, cause heat transfer property to descend through the gasification after the heat exchange; 2) the existing baffle plate of distribution aperture or the form of employing capillary and steam-generating bank welding of in minute journey bobbin carriage, being equipped with, there is complex structure in these liquid distributing devices, seal request is high, difficulty of processing is big, cause processing cost high, uneconomical, not energy-conservation.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, it is the object of the invention place that a kind of dry evaporator separatory even distribution device simple for structure, compact, effective and method for using are provided.Technical scheme of the present invention is to make gas-liquid refrigerant mixture separatory more even through the separatory even distribution device in the dry evaporator, and flashes to superheated fully along the interior length direction of tube bank, has effectively improved the utilization rate of evaporimeter heat transfer property and evaporation tube.
Technical scheme of the present invention concrete realization through following technical measures; A kind of dry evaporator separatory even distribution device; It is characterized in that it is made up of separatory uniform device and the tube sheet and the steam-generating bank that are associated; Described separatory uniform device is a cylindrical cone that top is little, the bottom is big, and it is 2.5 ° for 10mm-25mm, tapering highly, and the external diameter of separatory uniform device is adjusted according to the different inner diameters of steam-generating bank; The inside of separatory uniform device is conical bore and the following cylindrical hole that links to each other on the axial peviform; The tapering of the last conical bore of peviform is 10～20 °; The aperture of following cylindrical hole is 2.5mm-6mm; The degree of depth is 4mm-6mm: the composition of separatory even distribution device is that separatory uniform device small end is inserted in the mouth of pipe of all evapn tube bank and tube plate expanded-connecting or welding in the branch journey bobbin carriage first pass be installed in dry evaporator cold-producing medium feed liquor oral-lateral; Its big end is concordant with the mouth of pipe end face of steam-generating bank, and the external diameter of separatory uniform device and the internal diameter of steam-generating bank are interference fit.
Dry evaporator separatory even distribution device of the present invention and method for using are: the low-pressure gas-liquid refrigerant mixture is got in the branch journey bobbin carriage by the dry evaporator feed tube; Through the even separatory of separatory even distribution device in the first pass all evapn tube bank mouth of pipe; The gas-liquid refrigerant mixture is ejected in the every steam-generating bank uniformly, fully accomplishes the process of heat exchange.
The invention has the beneficial effects as follows; This dry evaporator separatory even distribution device has adopted the separatory uniform device of cylindrical shape to be directly installed in the mouth of pipe of steam-generating bank; Make gas-liquid refrigerant mixture separatory more even; Make full use of all steam-generating banks and carried out heat exchange, effectively improved the efficiency and the heat transfer property of dry evaporator.Having improved the efficiency of 15-20% than existing liquid distributing device, is a kind of compact conformation, and fabrication and installation are convenient, the energy saver that processing cost is low.
