Description

Technical field

This technical solution relates to the field of electric cleaning of gases from dust (dispersed suspensions) and can be used mainly in the power industry, in the chemical, metallurgical and building materials industries.

State of the art

Currently, there are various designs of electrostatic precipitators used for cleaning gases from dust (dispersed suspensions). In particular, from the patent for utility model of the Russian Federation No. 77797, publ. November 10, 2008, an electrostatic precipitator is known, including a housing, settling electrodes located in it, consisting of individual elements, and corona electrodes with a suspension system, a shaking mechanism, power supply and silos. Moreover, the elements of the precipitation electrodes are equipped with clamps installed along the height of the electrostatic precipitator, each of which is made in the form of a bracket fixed (welded) to the end of one element of the precipitation electrode and freely covering the end face of its neighboring element.

The installation of clamps on the elements of the precipitation electrodes ensures a constant distance between the corona and precipitation electrodes, i.e. the breakdown voltage along the height of the electrostatic precipitator will be uniform, thus improving the quality of cleaning.

However, the known technical solution according to patent No. 77797 has the following disadvantage. The known design of the electrostatic precipitator in the part of the node of the precipitation electrodes is non-universal and has low maintainability, since the latch on the outside of the bracket is made with the possibility of a rigid integral connection with the end face of the element of the precipitation electrode. In practice, in existing analogues, the clamps on the outside of the bracket are fixed by welding with the end face of one element of the precipitation electrode, and on the inside of the bracket the clamp is made with the possibility of detachable connection with the end face of another element of the precipitation electrode. Thus, by means of clamps, the assembly of a precipitation electrode consisting of several separate elements of the precipitation electrodes of a shorter length can be carried out. However, if it is necessary to carry out repairs in the electrostatic precipitator, the replacement of the clamp is possible only together with the replacement of the element of the precipitation electrode, or it is necessary to cut off the clamp and re-weld it to a new element of the precipitation electrode. It is worth noting that welding requires additional equipment, as well as additional staff qualifications, which further reduces maintainability. In addition, welding operations may be prohibited at the installation site of the electrostatic precipitators, which further reduces maintainability. In particular, the low maintainability of the known fixer is due to the need to use additional equipment to remove and / or install it on the end of the precipitation electrode element on the outside of the bracket, as well as in some situations, the inability to conduct maintenance and repair of the electrostatic precipitator without completely replacing the clamp and the precipitation electrode element, permanently connected to it from the outside of the bracket. The packaging and transportation of clamps and elements of the precipitation electrodes from the production site is additionally complicated due to the increase in overall dimensions, since the clamps are welded to the elements of the precipitation electrodes, which also reduces the maintainability of the structure. The elements of the precipitation electrodes in the known design are asymmetric, they cannot be turned over, interchanged or transferred from the middle position to the extreme within the limits of the formed precipitation electrode, consisting of individual elements.

The objective of this technical solution is to increase the maintainability of the electrostatic precipitator in the part of the site of the precipitation electrodes.

Disclosure

The object of this technical solution is an electrostatic precipitator, containing a housing, settling electrodes located in it, consisting of individual elements, and corona electrodes with a suspension system, a shaking mechanism, power supply and hoppers, precipitation electrode elements equipped with latches installed along the height of the electrostatic precipitator, each of the latches has the form staples and made with the possibility of detachable connection with the end face of the first element of the precipitation electrode from the inside of the staple.

The technical result is achieved by the fact that at the end of the element of the precipitation electrode made at least two cuts, and the latch further comprises at least two clamps on the outside of the bracket, made with the possibility of forming a detachable connection with at least two corresponding cutouts at the end of the second element of the precipitation electrode.

An embodiment is possible in which the latch on the outer side of the bracket further comprises at least one stamping configured to wedge the latch when connected to the end of the second element of the precipitation electrode on the outer side of the bracket.

In the context of the description of this utility model, the terms “one element of the precipitation electrode” and “another element of the precipitation electrode”, “first” and “second” elements of the precipitation electrode serve only to clarify that the clamp is designed to connect two elements of the precipitation electrodes with each other. Moreover, the type, size, shape, material and other properties of the said elements of the precipitation electrodes can at least partially coincide or differ without introducing any restrictions.

The technical result is an increase in maintainability of the electrostatic precipitator in the part of the site of the precipitation electrodes.

In the context of this utility model, maintainability is understood, in particular, as simplicity, ease and convenience of disassembling and assembling a structure by hand or with a minimum set of tools.

Additionally, in the elements 3 of the precipitation electrodes, which do not have cutouts 11 at the ends, during maintenance or repair of the electrostatic precipitator, the above-mentioned cutouts 11 can be made to install the latch 9.
