Description

Novel spraying structure

Technical Field

The utility model relates to an evaporative condenser field especially relates to a novel spray structure.

Background

The working principle of an evaporative condenser (evaporation cooling for short) is that a working fluid (pure water or other liquid) circulates in a coil of the evaporative condenser, and the heat of the working fluid is dissipated into spray water flowing through the outer surface of the coil through the coil. Meanwhile, air outside the unit enters from an air inlet grille on the base plate, the flowing direction of the air is opposite to that of water, a small part of water flowing upwards through the coil pipe is evaporated to absorb heat, and hot and humid air is exhausted to the atmosphere by a ventilator on the top of the evaporative condenser. The rest spray water falls into the bottom water tray, and is recirculated to the water distribution system by the spray pump and then is sprayed back to the coil pipe.

The spray system of the evaporative condenser is an important component of the evaporative condenser, and at present, the spray system mostly adopts a mode that a water supply pipe with a closed tail end is connected with a plurality of spray branch pipes, and one ends of the spray branch pipes are connected to the side wall of the water supply pipe. The spray head connected to the spray pipe at the rear end of the water supply pipe of the spray system has large spray water flow, the spray head connected to the spray pipe at the front end of the water supply pipe has small spray water flow, uneven water spray and poor cooling effect.

Disclosure of Invention

In order to solve the problem, an object of the utility model is to provide a novel structure that sprays that water spray effect is even, and the cooling effect is good.

In order to achieve the above object, the present invention adopts the following technical solutions: a novel spraying structure comprises an annular water supply pipe, a plurality of spraying branch pipes connected to the annular water supply pipe in parallel, and a plurality of water inlet pipes connected to one side of the annular water supply pipe; two water feeding branches are formed inside the annular water feeding pipe, the front ends of the two water feeding branches are connected with the water inlet pipe, the rear ends of the two water feeding branches are communicated together, the water quantity fed into the two water feeding branches by the water inlet pipe is equal, one end of each spraying branch pipe is connected to one water feeding branch, and the other end of each spraying branch pipe is connected to the other water feeding branch. Generally speaking, the flow pipe is thicker water pipe and spray branch pipe is thinner water pipe, and spray branch pipe and flow pipe's angle of connection is 90 degrees, and current single straight line flow pipe's structure, the end of intaking of many spray branch pipes is connected on a flow pipe lateral wall and the flow pipe end seals. In the process that rivers constantly move forward in the inlet tube, neglect the water yield that gets into spray branch, the total pressure of rivers is relatively unchangeable, and total pressure = dynamic pressure + static pressure. When water flows at the front end of the water supply pipe, because the water flows when moving, the dynamic pressure is high, the static pressure ratio is low, and the static pressure is the pressure which is generated when fluid flows and is vertical to the moving direction of the fluid, the water quantity entering the spraying branch pipe at the front end of the water supply pipe is low; when the water flow moves to the tail end of the water supply pipe, the tail end of the water supply pipe is closed, the water flow stops moving due to obstruction, the dynamic pressure is close to zero, and the static pressure is very high, namely the water entering the spray branch pipe is very large. Two water branch roads are sent to inside formation of water supply pipe in this scheme, two water branch road rear ends communicate together, when rivers flow to the rear end on sending water branch road like this, because communicate together again at the rear end, water still takes place the relative flow at water branch road rear end, though the velocity of flow reduces nevertheless can not reduce too much, the dynamic pressure can not reduce too much promptly, relatively, static pressure can not increase too much yet, just so make send water branch road front end and rear end to get into the water yield of spraying branch road and be approximate. In addition, two ends of the spray branch pipe are respectively connected to the two water supply branches, the water amount fed into the two water supply branches by the water inlet pipe is equal, and the water amount entering the spray branch pipe from each position on one water supply branch is approximate, so that the water amount entering the spray branch pipe from two ends of the spray branch pipe is almost equal. On a single spraying branch pipe, water flows enter from two ends and flow in the middle, so that the static pressure at each position on the single spraying branch pipe is uniform, namely the water sprayed out by the spraying heads arranged at each position is similar.

Furthermore, when only one water inlet pipe is connected to the annular water supply pipe, the front ends of the two water supply branches are connected with the water outlet of the water inlet pipe; the water inlet pipe is characterized in that a water distribution plate is arranged at the tail end of the water inlet pipe, the water distribution plate is vertically arranged on a central axis of the water inlet pipe, and the water distribution plate can equally distribute the water quantity of the water inlet pipe and send the water quantity into the two water supply branches. When only one water inlet pipe is connected to the annular water supply pipe, the front ends of the two water supply branches are connected with the water outlet of the water inlet pipe, a water distribution plate is arranged at the tail end of the water inlet pipe and is vertically arranged on an axial line of the water inlet pipe to divide water flow in the water inlet pipe into two parts so as to enable the water flow to flow into the two water supply branches respectively, and the water amount sent into the two water supply branches by the water inlet pipe is equal to each other.

Furthermore, the spray headers on a single spray branch pipe are arranged at equal intervals along the spray branch pipes, and the spray headers on two adjacent spray branch pipes are arranged in a staggered manner. When the spray header is specifically arranged, the spray range of the spray header is regarded as a circle; and in the range of the circle, the water sprayed at the position close to the circle center is large, and the water sprayed at the position far away from the circle center is small. In order to ensure that the water amount sprayed at each position is relatively uniform in the spraying range of the whole spraying structure, when the spraying heads are arranged on a single spraying branch pipe, the spraying heads are arranged at equal intervals along the spraying branch pipes, and when the positions of the spraying heads on two adjacent spraying branch pipes are considered, the spraying heads on the two adjacent spraying branch pipes are arranged in a staggered manner, so that the distance between the spraying head on one spraying branch pipe and the distance between the spraying head on the other spraying branch pipe and the adjacent spraying branch pipe is equal to half of the distance between the two adjacent spraying branch pipes. The spray heads are uniformly arranged in the spray range of the whole spray structure as much as possible, so that the water amount sprayed by each position in the spray range of the whole spray structure is more equal, and the spray effect is more uniform.

Furthermore, two water feeding branches of the annular water feeding pipe respectively comprise two straight line sections, and two ends of the spraying branch pipe are respectively connected to the two straight line sections. In order to facilitate the arrangement of the spraying branch pipes and the spraying heads, the two water feeding branch pipes are correspondingly arranged on two parallel straight line sections, and the two ends of each spraying branch pipe are respectively connected to the two straight line sections, so that the arrangement of the spraying branch pipes is facilitated.

Furthermore, the connection position of the spray branch pipe and the water supply branch is positioned at the lower end of the annular water supply pipe. The spraying branch pipe is connected with the water supply branch, and the position of the connecting point is positioned at the lower end of the annular water supply pipe. On one hand, under the action of gravity, the water in the annular water supply pipe can more easily enter the spraying branch pipe; on the other hand, the spray branch pipe is much thinner than the annular water supply pipe, and the spray branch pipe is arranged at the lower side, so that a space is reserved for installing other equipment or structures on the spray branch pipe.

Furthermore, the novel spraying structure further comprises a water collector, wherein the water collector is arranged on the spraying branch pipe through an angle iron pressing plate positioned on the upper part of the water collector, and the lower end of the water collector is positioned on the inner side of the annular water feeding pipe. Because the water collector structure is located above the spray pipe, the spray branch pipe is thinner than the annular water supply pipe, the spray branch pipe is arranged at the lower side, a space is reserved for installing the water collector on the spray branch pipe, the water collector is installed on the spray branch pipe through an angle iron pressing plate located at the upper part of the water collector, the lower end of the water collector is embedded into the inner side of the annular water supply pipe, the height of the whole structure is reduced, and the installation is simpler and more convenient.

According to the technical scheme, the water supply pipe is arranged to be an annular water supply pipe, a plurality of spraying branch pipes are connected to the annular water supply pipe in parallel, and a plurality of water inlet pipes are connected to one side of the annular water supply pipe; two water feeding branches are formed inside the annular water feeding pipe, the front ends of the two water feeding branches are connected with the water inlet pipe, the rear ends of the two water feeding branches are communicated together, the water quantity fed into the two water feeding branches by the water inlet pipe is equal, one end of each spraying branch pipe is connected to one water feeding branch, and the other end of each spraying branch pipe is connected to the other water feeding branch.

As shown in fig. 1, a novel spraying structure comprises an annular water supply pipe 1, a plurality of spraying branch pipes 2 connected to the annular water supply pipe in parallel, and a plurality of water inlet pipes 3 connected to one side of the annular water supply pipe; two water feeding branches are formed inside the annular water feeding pipe, the front ends of the two water feeding branches are connected with the water inlet pipe, the rear ends of the two water feeding branches are communicated together, the water quantity fed into the two water feeding branches by the water inlet pipe is equal, one end of each spraying branch pipe is connected to one water feeding branch, and the other end of each spraying branch pipe is connected to the other water feeding branch. Two water supply branches are formed inside the water supply pipe in the scheme, and the rear ends of the two water supply branches are communicated together. The water flow flows in from the two ends of the annular water supply pipe, and the rear ends of the water supply branches are communicated, so that the water still flows relatively at the rear ends of the water supply branches, the flow rate is reduced but not static, namely, the dynamic pressure is not reduced too much, and the static pressure is not increased too much relatively, so that the water quantity entering the spraying branch pipe from the front end or the rear end of the water supply branch is approximate. In addition, two ends of the spray branch pipe are respectively connected to the two water supply branches, the water amount fed into the two water supply branches by the water inlet pipe is equal, and the water amount entering the spray branch pipe from each position on one water supply branch is approximate, so that the water amount entering the spray branch pipe from two ends of the spray branch pipe is almost equal.
