Problems solved by technology

Because the flue gas condensate has certain acidity and contains harmful components such as gypsum, after being brought into the atmosphere by the flue gas, it will fall down and form chimney acid rain (or gypsum rain), causing damage to the buildings and ecological environment around the chimney

Embodiment 1

[0036] Such as Figure 1 to Figure 7 As shown, in this embodiment, the liquid collection tank 2 includes a ring-shaped bottom plate 21, and the bottom plate 21 is inclined at an acute angle α with the horizontal plane; the acute angle α is between 45 and 1 degree; preferably, α is 10 degrees. The outer periphery of the bottom plate 21 is fixed in contact with the inner wall of the glass fiber reinforced plastic cylinder 1, and the inner periphery is connected with a baffle plate 22 extending horizontally upwards to form a channel for flue gas condensation and acid liquid to flow. Preferably, the bottom plate 21 and the baffle plate 22 are both made of glass fiber reinforced plastic, and both are integrated.

[0037] Thus, the flue gas condensate and dew acid liquid along the inner wall of the chimney or freely falling will flow to the annular bottom plate, and the flue gas condensate and dew acid liquid will be collected under the joint action of the inner peripheral baffle a...

Embodiment 2

[0045] Such as Figure 8 and Figure 9 As shown, in this embodiment, the bottom plate 21 of the liquid collection tank 2 is in the shape of a cone that gradually slopes downward from the inner circumference to the outer circumference, and the outer circumference of the bottom plate 21 is in contact with the inner wall of the glass fiber reinforced plastic cylinder 1 to form a smoke supply. A conical channel through which gas condensation and acid liquid flow. The lower end of the bottom plate 21 is inclined at an acute angle α with the horizontal plane, so as to ensure that the flue gas condensation and dew acid liquid in the liquid collection tank will flow to the lowest point of the bottom plate under the joint restriction of the bottom plate and the inner wall of the glass fiber reinforced plastic inner chimney.

[0046] By setting the bottom plate into a tapered shape, the liquid collecting tank can be formed only by the bottom plate and the inner wall of the glass fiber ...

Embodiment 3

[0048] Such as figure 1 and figure 2 As shown, in this embodiment, a ring-shaped liquid collection tank 2 is provided at different heights of the glass fiber reinforced plastic inner chimney, and the inclination direction of each liquid collection tank 2 is consistent, so that the lowest points of each liquid collection tank 2 are in the same vertical position. on-line.

[0049] In this embodiment, the glass fiber reinforced plastic inner chimney is in the shape of a cone that gradually widens from top to bottom, and the width of the bottom plate 21 of each liquid collection tank 2 gradually widens from top to bottom, so that each liquid collection tank 2 can be placed on different vertical surfaces. The flue gas condensate and dew acid liquid is collected, and the lower liquid collection tank 2 can collect the flue gas condensate and dew acid liquid overflowing from the liquid discharge tank 4 corresponding to the upper liquid collection tank 2, so as to realize the liquid...

Abstract

The invention discloses a smoke condensed dew acid liquid collecting device for a glass fiber reinforced plastic inner chimney. The smoke condensed dew acid liquid collecting device comprises at least one circle of annular liquid collecting groove formed in the inner wall of the glass fiber reinforced plastic inner chimney, the liquid collecting groove is obliquely arranged with the horizontal plane for an acute angle alpha, and the lowest part of each liquid collecting groove communicates with a liquid draining pipe through an outlet pipe penetrating through the glass fiber reinforced plastic inner chimney. After the technical scheme is adopted, smoke condensed dew acid liquid in the chimney falls into the liquid collecting groove and gathers at the lowest point along the liquid collecting groove obliquely arranged, and the smoke condensed dew acid liquid is discharged to the outer part of the chimney through the liquid draining pipe and is collected, so that chimney acid rain formed by the emission of the smoke condensed dew acid liquid with smoke is avoided, and the chimney surrounding environment is prevented from being damaged; and the inner part of the chimney is also prevented from being corroded in the drop process of the smoke condensed dew acid liquid. At the same time, the smoke condensed dew acid liquid collecting device is simple in structure, great in effect and suitable for popularization and use.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic chimney in the field of electric power equipment, in particular to a flue gas condensed dew acid liquid collecting device for a glass fiber reinforced plastic inner chimney. Background technique [0002] The tall chimney of thermal power plant is an important structure. According to relevant regulations, it should meet the requirements of the structural design base period of 50 years and the process system design life of 30-35 years. FRP is widely used in anti-corrosion equipment and projects such as chemical industry, metallurgy, shipbuilding and aerospace. FRP chimneys usually adopt inner and outer cylinder structures. Among them, the outer cylinder adopts reinforced concrete structure, and the inner cylinder of glass fiber reinforced plastic is mainly composed of glass fiber reinforced plastic produced by winding process. The joints of the FRP chimney are connected by wet paste, and the se...
