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

[0040] Such as Figure 1 to Figure 5 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.

[0041]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 an...

Embodiment 2

[0049] Such as Figure 6 and Figure 7 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 to ensure that the flue gas condensed and dew acid liquid in the liquid collection tank flows to the lowest point of the bottom plate under the joint restriction of the bottom plate and the inner wall of the chimney.

[0050] 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 chimney, which simplifies the structure of the liquid collectin...

Embodiment 3

[0052] Such as Figure 8 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.

[0053] 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 collection Th...

Abstract

The invention discloses a flue gas condensation and dew formation acid fluid collection device for a glass fiber reinforced plastic internal chimney. The flue gas condensation and dew formation acid fluid collection device comprises at least one circle of annular fluid collection tank formed in the inner wall of the glass fiber reinforced plastic internal chimney, wherein the fluid collection tanks are obliquely formed in the way of forming acute angles alpha with the horizontal plane; a fluid discharge hopper is arranged at the lowest part of each fluid collection tank; and the fluid discharge hoppers communicate with a fluid discharge pipe arranged in the glass fiber reinforced plastic internal chimney. After adoption of the technical scheme, a flue gas condensation and dew formation acid fluid in the chimney can fall into the fluid collection tanks, can be collected at the lowest parts along the obliquely formed fluid collection tanks, and then, can be discharged outside the chimney via the fluid discharge pipe to be collected, so that the flue gas condensation and dew formation acid fluid is prevented from being discharged outside together with flue gas, accordingly, the formation of chimney acid rain is avoided, and damage to the ambient environment of the chimney is also avoided. Meanwhile, the fluid discharge pipe arranged in the chimney can vertically extend in the shortest distance, so that the length of the fluid discharge pipe can be reduced as much as possible.

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...
