Problems solved by technology

Up to now, there are secondary filter products that can filter well, but the biggest defect is that when the cooling water flows through the secondary filter, the water flow is greatly disturbed, and this disturbance will affect the flow field. Have a large

Embodiment Construction

[0060] The present invention will be further described below in conjunction with drawings and embodiments.

[0061] Taking a power plant condenser circulating water pipeline diameter as 1420mm as an example, the design method of the steam turbine condenser cooling water secondary filter screen disc-shaped screen frame of the present invention comprises the following steps:

[0062] (1) Determine the geometric conditions of the disc-shaped screen frame:

[0063] For the convenience of illustration, the disc-shaped filter frame is simplified and placed in the xyz-Cartesian coordinate system, as shown in image 3 shown. It is known that the inner radius of the circulating water pipe of the condenser of the power plant is 710mm, and the radius of the disk along the x-axis equator is a, the radius of the equator along the y-axis is b, and the polar radius is H. Then the disc-shaped filter screen frame should first satisfy: the equatorial radius of the disc along the x-axis is equ...

Abstract

A gas turbine condenser cooling water secondary filter screen comprises a shell, a sewage discharge and suction mechanism, a power device and a sewage discharge outlet, wherein the sewage discharge and suction mechanism is disposed in the shell and comprises a disc filter screen framework and a double-sided sewage suction opening formed below the disc filter screen framework, a driven bevel gear fixedly connected to the rotary shaft of the sewage discharge and suction mechanism is meshed with a power bevel gear fixedly connected to the shaft end of the power device, and the sewage discharge outlet is formed in the shell located on the lower portion of the sewage discharge and suction mechanism. The invention further provides the design method of the disc filter screen framework. The gas turbine condenser cooling water secondary filter screen has the advantages that flowing of water flows of a condenser inlet water chamber can be improved, the water flow uniformity coefficient is increased, flow rectifying is achieved, the heat exchanging conditions of the cooling tube bundles in a condenser are improved effectively and reasonably, condenser vacuum is increased, power plant standard coal consumption rate is lowered, and energy is saved; the design of the disc filter screen framework is the key technology of the gas turbine condenser cooling water secondary filter screen. In addition, the design method of the disc filter screen framework is scientific and reasonable.

Description

technical field [0001] The invention belongs to the technical field of filtering equipment, and relates to a design method for a secondary filter screen for cooling water of a steam turbine condenser and a disc-shaped filter screen frame thereof. The water flow in the inlet water chamber improves the vacuum of the condenser and saves energy. Background technique [0002] The power industry is the most important basic energy industry in the development of my country's national economy, and it is also one of the industries with high energy consumption and high pollution. In my country, thermal power generating units occupy a dominant position in the power supply, and the main economic and technical index for evaluating thermal power generating units is the standard coal consumption rate of power supply. In order to reduce the standard coal consumption rate, it is necessary to increase the vacuum degree of the steam turbine condenser. The vacuum degree of the condenser mainly...
