Mounting locating device for flushing spraying system of wet electrical dust precipitator

Abstract

The invention relates to an installation and positioning device for a flushing and spraying system of a wet electrostatic precipitator, comprising a top side beam, a middle frame top beam, a limit casing, a casing and a middle connecting pipe; the top side beam is The two are respectively arranged on both sides of the top beam of the middle frame, the limit casing is fixed on the top side beam on one side, and the inlet pipe connection is arranged on the top side beam on the other side; the casing is arranged on the top beam of the middle frame , the middle connecting pipe is set on the casing and can move forward and backward; the front and rear ends of the middle connecting pipe are respectively connected to the front spray pipe and the rear spray pipe; the other end of the front spray pipe is connected to the inlet pipe, and the other end of the rear spray pipe is connected One end is connected with the limit sleeve. An installation and positioning device for a wet electric spray system: the spray pipe is installed in the upper part of the wet electric middle frame, the installation is simple, fast, firm and reliable; compared with other installation methods, the number of flange connections is reduced, and the installation work intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to an installation and positioning device for a flushing and spraying system of a wet electrostatic precipitator. Background technique [0002] Wet electrostatic precipitator is a kind of dust removal equipment used to deal with tiny dust and fine particles. As my country's requirements for flue gas and dust emissions from coal-fired units are increasing, wet electrostatic precipitators are gradually applied to the flue gas emission system; wet electricity can effectively remove fine particles and SO by improving dust removal efficiency. 3 and other pollutants to achieve ultra-low emission performance indicators. [0003] The spray system is also the biggest difference between the internal structure of wet and dry electrostatic precipitators. The wet electrostatic precipitator sprays and washes the anode plate with dedusting water through the spray system, so that th...

Problems solved by technology

[0004] The components of the wet electrostatic precipitator are complicated, the installation requirements are more, and the installation period is longer

In order to ensure the coverage of the wet electric spray flushing system, the positioning of the spray system must be precise; the distance of the spray pipe is long, and the deviation of the supporting steel frame is large during installation and positioning, so it is necessary to have an adjustment structure to reduce the installation error; when installing the spray system, the wet The overall anti-corrosion of electricity has been completed, which limits the hot-fire construction of welding

After the wet power is put into operation, the thermal expansion of the frame causes the displacement of the spray pipe and the fixing device, resulting in the deformation of the spray pipe
