Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0028] see Figure 1-Figure 5, this embodiment provides a pulse filter blowback system for gas turbines, including a rainproof shed 1, a tube plate 2 is installed inside the rain proof shed 1 and close to the air outlet, and the tube plate 2 is far away from the outlet of the rain proof shed 1 The filter element holder 3 is bolted to the side, and the filter element holder 3 is arranged in an array. There is a circular large hole inside the tube plate 2 and at the filter element support 3, which is a channel for filtered clean air. The filtered clean air is separated from the dirty air before filtration. The filter element holder 3 is fixed with a filter element 4. The inside of the rainproof shed 1 and below the fi...

Abstract

The invention discloses a pulse filtering blowback system for a gas turbine, and belongs to the technical field of filtering blowback. The pulse filtering blowback system for the gas turbine comprisesa rainproof shed; a tube plate is installed in the rainproof shed and close to an air outlet; a filter element support is bolted to the side, away from an outlet of the rainproof shed, of the tube plate; a filter element is fixed on the outside of the filter element support; a drain channel is arranged inside the rainproof shed and below the filter element. According to the pulse filtering blowback system for the gas turbine, high-pressure airflow passes through fan blades in a connecting and fixing cylinder and acts on the fan blades, the fan blades and the connecting and fixing cylinder outside the fan blades can be driven to rotate, and therefore, an inclined nozzle is made to rotate; the air flow can spray the inner part of the filter element in circles. Compared with a mode in whichthe axis direction of the filter element coincides with the axis of the filter element, the above mode makes the air flow generated by the nozzle move closer to the filter element, and therefore, larger acting force can be generated on dust attached to the filter element, and the problem that the backflushing cleaning effect is poor is solved.

Description

technical field [0001] The invention relates to the field of filter blowback, in particular to a pulse filter blowback system for a gas turbine. Background technique [0002] Gas turbine generally refers to a combustion engine. In the broad concept of a combustion engine, household water heaters, gas stoves, and even lighters can be considered as a type of combustion engine. According to its working principle, a burner can be defined as a kind of A kind of equipment that converts substances into heat energy through combustion, a chemical reaction method, that is, air and fuel are mixed in an appropriate proportion through a premixing device to make them fully combustible. These substances can cause damage to the gas turbine. Currently, recoil systems are added to the filter equipment of some gas turbines to realize the self-cleaning of the filter element and reduce the frequency of replacement of the filter element. However, the recoil system is generally cleaned by simple h...
