Problems solved by technology

A lot of compressed air and energy are wasted. At the same time, the inlet and outlet valves also operate frequently in the ash-free state. The compressed air consumption is high, and the mechanical wear of the equipment is large, which reduces the service life and increases the maintenance of the equipment.
[0009] As far as the contact level gauges and passive nuclear level gauges produced at home and abroad are concerned, there are two main problems that plague us: 1. The source of fly ash in thermal power plants often changes, and even the radioactivity of some coal sources The difference is very large (up to 100 times or more), and the measurement of the material level is calibrated based on the radioactivity of the coal source. Therefore, when the coal source changes, this product must be re-calibrated to work normally. It is convenient to use. Very poor, and the practicability is not ideal; 2. There is no real-time measurement and control function of the material level, similar to a switch, which only recognizes the full and empty materials. The accuracy of this product is relatively poor, and the system that requires more accurate material level cannot Be applicable

Embodiment

[0035] Such as image 3 The trend diagram shown in combination with the auxiliary time curve diagram can judge the suspension of the ash hopper and the damage of the valve. The operation mode after the transformation is mainly based on the material level signal control:

[0036] (1) Under normal circumstances, each conveying unit is automatically programmed to operate according to the set parameters. The process is to start the operation and the feed valve is opened (the conveying tank starts to load ash) --- the material level of the conveying tank reaches the set value or the set ash loading When the time is up---the feed valve is closed---the discharge valve is opened-the intake valve is opened (start conveying)-the pressure of the conveying pipeline drops to the set value---the intake valve is closed (a conveying cycle ends) - go to next loop.

[0037] (2) This program sets two parameter setting windows, which are the setting of the ash level height of the feed material a...

Abstract

The invention belongs to the technical field of application of industrial dust removal and environmental protection, and particularly discloses a storage pump energy saving detection control instrument. The storage pump energy saving detection control instrument is composed of a control instrument mainframe, a function keyboard, a parameter display window, a sensor signal conversion transmission module, a sensor lock, a sensor probe connecting plate and a monitoring assembly. The storage pump energy saving detection control instrument and the working method thereof have the beneficial effectsthat interference factors such as high temperature, temperature drift, friction, false alarm of a hanging material, interference of suspended powder, rapid feeding and air pressure impact, electrostatic interference of ash powder, coal product change and the like are avoided, during application, actual ash level height can be automatically tracked and rectified based on the initial material parameter state of the material, the actual ash level in the storage pump can be accurately measured, and a precise signal is provided for cindervalve opening and closing in the next step; gas consumption is reduced, the service life of the valve is prolonged, pipeline abrasion is reduced, the service life of an air compressor is prolonged, circulating cooling water of the air compressor is saved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of industrial dust removal and environmental protection applications, and specifically relates to an energy-saving detection and control instrument for a warehouse pump and a working method thereof, which are suitable for energy-saving and control of pneumatic ash conveying in mines, electric power and metallurgy. Background technique [0002] Pneumatic conveying is a comprehensive technology, which involves fluid mechanics, material science, automation technology, manufacturing technology and other fields. It is a high-tech project with high conveying efficiency, less land occupation, economy and no pollution. In recent years, pneumatic conveying technology has been rapidly developed and applied in various fields, especially new devices with high dense phase (solid-gas mixing ratio), low energy consumption, large capacity and long distance are constantly coming out. High dense phase and low speed conveying ...
