Embodiment Construction

[0045] Hereinafter, the present invention will be described in detail using embodiments shown in the drawings. However, unless otherwise specified, the components, types, combinations, shapes, and relative arrangements thereof described in this embodiment do not limit the scope of the present invention thereto, but are merely illustrative examples.

[0046] Figure 18 It is a schematic diagram (perspective view) of the discharge electrode of the wet-type electrostatic precipitator of this embodiment. The wet electrostatic precipitator 100 using the discharge electrode of this embodiment has an overall external shape by the casing 102 that accommodates the discharge electrode 10 and the dust collecting plate 108 . Furthermore, the housing 102 has an inlet 104 for introducing exhaust gas, and an outlet 106 for discharging the exhaust gas after collecting dust particles. In the casing 102 , the main surfaces of the discharge electrode 10 and the dust collecting plate 108 face e...

Abstract

The invention provides a discharge electrode of a wet electric dust collector and an assembly stand for the discharge electrode, which simplifies the assembly process of the discharge electrode and improves the strength of the assembled discharge electrode. The discharge electrode of the wet electric dust collector is characterized by having: a pair of outer frame tubes (12) installed with discharge needles (16) and arranged in a transverse direction; and a pair of outer frame tubes (12) installed with discharge needles (16) arranged in a transverse direction between the outer frame tubes. A plurality of inner frame tubes (14); and a transverse frame tube (18) that connects the outer frame tube and the inner frame tube side by side, at the connection position of the transverse frame tube and the outer frame tube, and at the connection position between the transverse frame tube and the inner frame tube. A connecting member (20) is installed at the connecting position. The connecting member has: a main body (22) with an insertion hole (24) for inserting the horizontal frame pipe; and an end extending from the main body and embedded in the outer frame pipe or the inner frame pipe. In the embedded part (26), the transverse frame tube communicates with a plurality of insertion holes and connects the outer frame tube and the inner frame tube side by side, thereby forming a frame-shaped discharge electrode (10).

Description

technical field [0001] The present invention relates to a discharge electrode of a wet-type electric dust collector and an assembly stand for the discharge electrode, and particularly relates to a technique for simplifying the assembly process of the discharge electrode and improving the strength of the assembled discharge electrode. Background technique [0002] The discharge electrode of the wet-type electrostatic precipitator is required to easily cause corona discharge to charge the mist or dust in the exhaust gas. On the other hand, the flow of the exhaust gas causes the discharge electrode to vibrate and generate stress. Due to this stress, Therefore, there are also requirements for mechanical strength. The shape of the discharge electrode satisfying these requirements is disclosed in Patent Document 1. A tubular discharge material or the like is used as the base material of the discharge electrode. Discharge needles are arranged in a vertical direction on the opposit...
