Backblowing regenerative soot cleaning time counting device and method for dust remover filter element

Abstract

The invention relates to an auxiliary test device for a dust remover filter element, in particular to a backblowing regenerative soot cleaning time counting device and method for the dust remover filter element, and belongs to the field of backblowing dust removing electric control counting of a dust remover. The backblowing regenerative soot cleaning time counting device comprises a filter; the filter comprises a clean gas chamber and a dusty gas chamber which are connected with two pressure-sensitive membrane probes of a pressure difference transmitter respectively; the pressure difference transmitter is connected with a pressure difference control instrument; the pressure difference control instrument is connected with an impulse control instrument; the impulse control instrument is connected with a counter and an electromagnetic pulse valve; the electromagnetic pulse valve is mounted on a backblowing pipeline of the filter. The device and method are reasonable in design, and accurate and full-automatic in backblowing time counting; through the adoption of the backblowing regenerative soot cleaning time counting device, the impact of backblowing times on the filter element and other parts of equipment can be observed effectively, so that the application and popularization values are very high.

Description

technical field [0001] The invention relates to an auxiliary device for testing a filter element of a dust collector, in particular to a device and method for counting the number of times of dust removal by blowback regeneration of a filter element of a dust collector, and belongs to the field of electric control counting of the blowback dust removal of a dust collector. Background technique [0002] In recent years, due to the rapid development of China's economy, the demand for energy is increasing. However, China's energy reserves are mainly coal, and other resources such as oil and natural gas are scarce. In China's energy consumption structure, coal accounts for nearly 70% of the total energy consumption. Coal consumption is mainly based on coal combustion and coal gasification. Coal ash in coal will be produced along with the utilization of coal. Coal ash will not only pollute the environment, increase the dust content in the environment, but also corrode and wear equi...

AI Technical Summary

Problems solved by technology

The regeneration of the filter element is mainly completed by online back blowing. During the use of the back blowing system, it will affect various performances of the filter system components, especially one of the main factors affecting the service life of the filter element is the number of back blowing. The service life of the entire blowback system will be shortened accordingly with the increase of blowing times, but the relationship between the blowback times and the service life of the filter elements cannot be accurately judged, and the influence of the blowback times on the filter elements cannot be accurately judged.
