Distributor applied to falling film type evaporator

Abstract

The invention discloses a distributor applied to a falling film type evaporator. The distributor comprises a baffle plate, a pressure box and a gravity box, wherein first through holes are uniformly and closely distributed in the bottom of the gravity box, the bottom of the gravity box are provided with a plurality of clapboards in the width direction, the pressure box is contained in the gravity box, an interval exists between the circumference of the pressure box and the circumference of the gravity box, second through holes are closely distributed in the top of the pressure box, the baffle plate is arranged above the pressure box, the two sides of the baffle plate are fixed on the gravity box, pore plates are arranged on the edges of the baffle plate and are provided with cover plates, intervals are reserved between the pore plates and the cover plates to form ventilation slots, and an inlet tube is arranged on the baffle plate and is communicated with the pressure box. According to the distributor applied to the falling film type evaporator, which is disclosed by the invention, the pressure potential energy and the gravity potential energy are mutually matched to distribute coolant working mediums, so that the reliability is high, the uniformity is good, the fluid distribution is uniform, the coolant working mediums are prevented from splashing and leaking, and the pressure loss is small; the distributor is matched with the falling film type evaporator, so as to be capable of fully exerting the performance advantages of the falling film type evaporator and to have good manufacturability.

Description

technical field [0001] The invention relates to an evaporator component, in particular to a distributor used in a falling film evaporator. Background technique [0002] The working process of the falling film evaporator is generally: the high-temperature condensed liquid delivered from the condenser passes through a throttling device (such as: electronic expansion valve, throttling orifice, etc.) and then becomes a mixture of low-temperature liquid and low-temperature gas. The fluid then enters the distribution device in the falling film evaporator, flows out of the distribution mechanism after passing through horizontal, vertical or 3-layer, 4-layer, or 5-layer flow as required, and drips onto the heat exchange tube to transfer the cooling capacity to the user. After being evaporated, it enters the suction port of the compressor, and after being compressed, it is discharged into the condenser. Among them, in the above process, the uniform distribution of refrigerant workin...

AI Technical Summary

Problems solved by technology

Among them, in the above process, the uniform distribution of refrigerant working fluid is very important, and the distribution mechanism is at the core of each component of the falling film evaporator, but the distribution mechanism in the falling film evaporator is not enough in terms of distribution uniformity. Ideal, can not meet the requirements, therefore, in order to ensure the uniform distribution of refrigerant working fluid, it is very necessary to design a reasonable and precise processing distribution mechanism
