Straight-through electric bag composite dust collector

Abstract

The invention discloses a straight-through electrostatic bag dust collector and relates to a dust collector. The electrostatic bag dust collector is provided with a casing, an inlet hopper, a primary electrostatic dust collecting device, a secondary electrostatic dust collecting device, a filter bag filter device, a pulse jetting device, an air cleaning chamber, an outlet hopper, a power supply thermal-insulation case and ash buckets. The inlet hopper is arranged at the front end of the casing, smoke enters the inlet hopper from an inlet of the inlet hopper, air flow uniformly distributing plates with flow guide blades are arranged in the inlet hopper, and an outlet of the inlet hopper is connected with the front end of the casing. The primary electrostatic dust collecting device is arranged at the front end of the casing, and the filter bag filter device is arranged on the upper portion of the rear end of the casing. The secondary electrostatic dust collecting device is arranged on the lower portion of the rear end of the casing, and an outlet of the secondary electrostatic dust collecting device is connected with a smoke inlet in the top of the filter bag filter device. The pulse jetting device is located in the air cleaning chamber, and the outlet hopper is communicated with a smoke outlet of the air cleaning chamber. The power supply thermal-insulation case is arranged on the upper portion of the primary electrostatic dust collecting device, the power supply thermal-insulation case is used for insulating the primary electrostatic dust collecting device, and the ash buckets are arranged at the bottoms of the primary electrostatic dust collecting device and the secondary electrostatic dust collecting device.

Description

technical field [0001] The invention relates to a dust collector, in particular to a straight-through electric bag composite dust collector without a flow equalizing device in a transition zone. Background technique [0002] Chinese patent ZL200420040846.X discloses an electric bag composite dust collector, in which a flue gas flow equalization device is installed in its transition area. Flue gas equalizer. The main purpose of this splitter is to even out the airflow into the filter bag area and prevent scouring of the filter bags. However, when the airflow of the electric bag composite dust collector flows through the inlet horn and the front stage electric field area, when it flows to the filter bag area, the airflow is already very uniform under the action of the inlet horn equalizer plate and the electric field area plate channel. The airflow velocity is about 1m / s, the airflow velocity is low, and the coarse dust has been captured in the electric field area of ​​the p...

[0013] (2) Disadvantages of non-straight-through structure with confluence flue at the top

The current environmental protection requirements have been greatly improved, and the emission requirements are near zero emissions. The existence of the bypass system cannot meet the overall emission improvement. The bypass smoke box device is completely unnecessary.
