Air volume controller for cyclone dust collectors

Abstract

The invention provides an air volume controller of a cyclone dust collector, which belongs to the technical field of the environmental protection. The cyclone dust collector comprises a dedusting tank and a plurality of cyclones arranged inside the dedusting tank. Each cyclone comprises a cyclone unit, a guider arranged on the cyclone unit, and an air-guide tube inserted on the guider and extending into the cyclone unit. The cyclone dust collector is characterized in that an air volume controller is arranged above the upper supporting plate; the air volume controller comprises a valve base, an openable / closable valve cover and an electrohydraulic pusher; the valve base is mounted on the upper plane of the upper supporting plate; an opened end is formed at the upper part of the valve base; the openable / closable valve cover is positioned above the valve base and used for covering the opened end at the upper part of the valve base; the electrohydraulic pusher is mounted at the top of the dedusting tank; and the lower end of the electrohydraulic pusher extends inside the cavity of the dedusting tank and is coupled to the openable / closable valve cover. The invention has the advantage of being favorable for ensuring an extremely-high dust collection efficiency of the cyclone dust collector.

Description

technical field [0001] The invention relates to an air volume control device of a cyclone dust collector, which is used in a cyclone separation dust removal device for dedusting CDQ flue gas in a coking plant of an iron and steel enterprise, and belongs to the technical field of environmental protection facilities. Background technique [0002] As is well known in the industry, a cyclone dust collector is composed of dozens to thousands of cyclones arranged in parallel, and each cyclone includes a cyclone, a guide placed on the cyclone, and a The air guide tube on the guide and the lower part extending into the cyclone, the cyclone is installed on the lower pallet in the dust removal box, the air guide tube is installed on the upper pallet in the dust removal box, the cyclone The structure of the structure can be seen by the name of the applicant on September 27, 2006 as "cyclone", the authorization announcement number is CN200977480Y, and will not be described in detail her...

AI Technical Summary

Problems solved by technology

On the cyclone separation dust removal equipment, in the air circulation system composed of cyclone dust collectors, fans, valves, and pipes, due to production needs, the opening of the fan valve is often adjusted to meet the air volume required for production. The process will cause fluctuations in air volume, resulting in large fluctuations in the actual processing air volume allocated to each cyclone, often causing the actual processing air volume of each cyclone to exceed the rated air volume range

However, when the actual processing air volume of the cyclone is greater than (or less than) the rated air volume, it will cause a sharp drop in dust removal efficiency and increase the amount of dust entering the fan. cost of production
