Intelligent absorption type transmission separating system with synchronous frequency conversion control

Abstract

The invention relates to a smoke desulfuration intelligent synchronous variable frequency adjustable adsorption transmission separation system, belonging to the environment protection technique. Based on present variable frequency adjustable adsorption transmission separation system, the invention develops the special digital control system whose core is the PC, and via driving the variable frequency speed adjuster to realize the digital control on each main motor, and realize the real-time synchronous control on the filtration belt, the vacuum pump, and the humidity detecting unit. The data collection and accidence diagnose system uses the remote and on-site alternative control, combines the image collection system, to apply the operation of workers and realize the unmanned operation and the automatic parameter collection to be feedback to the workshop database. Since the invention uses the special digital control system to realize the digital control on each main motor, the real-time adjust of adhesive tape rotational speed with the water rate of gesso can be solved to avoid the quality decrease. All the sensors have the self-cleaning function to avoid the erosion and pollution of elements.

Description

technical field [0001] The invention relates to an intelligent synchronous frequency conversion control adsorption transmission separation system for flue gas desulfurization, which belongs to the technical field of environmental protection. Background technique [0002] Thermal power generation enterprises will produce a large amount of sulfur-containing flue gas in the process of burning coal, and venting will pollute the air. Treating sulfur-containing flue gas is not only beneficial to environmental protection, but also produces high-quality gypsum by-products during the treatment process. , the transmission and filtering mechanism of the existing system is composed of a filter belt and an adhesive tape. The adhesive tape is driven to circulate through the frequency conversion control drive mechanism. The filter belt runs synchronously with the adhesive tape through the pressing mechanism. While advancing forward, the liquid material passes through the filter belt and en...

AI Technical Summary

Problems solved by technology

[0003] There are many deficiencies in the existing adsorption transmission separation system: 1. Since the gypsum separated by the filter belt has strict moisture content requirements, it is necessary to regularly extract gypsum samples manually and send them to a special laboratory for moisture content analysis. As a result, manually adjusting the speed of the belt drive mechanism can basically meet the requirements of moisture content

And this satisfaction is also temporary, because the mechanism cannot guarantee the stability and balance of the flow of gypsum slurry into the separation system, so this sampling analysis and speed adjustment must be frequent

In this way, the water content of gypsum cannot always be guaranteed within the specified range, the quality of gypsum cannot be reliably guaranteed, and the operating cost is also greatly increased.

2. The adsorption transmission separation system adopts the DCS control system, the control objects are relatively scattered, the man-machine interface cannot be achieved, the automatic control ability is low, and there are deficiencies in several aspects such as intensification, intelligence, and efficiency.

3. Since the service object of the adsorption transmission separation system is gypsum slurry, which is highly corrosive and polluting, the various sensors attached to the adsorption transmission separation system do not have self-cleaning functions, which makes the operation stability of the sensing elements and The accuracy of detection data is reduced, and there are many system failures
