Description
Technical field:
This utility model relates to a kind of membrane panel smoking mouth swan neck system.
Background technology:
According to China's power planning, it is contemplated that 2015-2020, NO
X
Discharge capacity will more than SO
2
Discharge capacity, becomes the big acid contaminant of China first, and therefore, country forcibly administers the NO of thermal power plant by regulation
X
Discharge capacity, along with the development of China's power industry, NO
X
Discharge capacity grow with each passing day, it is well known that NO
X
Pollution can form acid rain, photochemical fog, destroys ecological environment, and its impact increasingly causes concern and the attention of people, some old power plant NO of present stage
X
Discharge capacity of a relatively high, do not meet national legislation NO
X
The requirement of discharge capacity, it is necessary to carry out transformation and install out of stock device additional, to reduce NO
X
Discharge capacity, the flue-gas temperature of existing economizer bypass place used does not reach the temperature needed for out of stock device, and this allows for denitration reaction and carries out insufficient, and denitration effect is very undesirable.
Summary of the invention:
The purpose of this utility model is to provide a kind of membrane panel smoking mouth swan neck system.
Above-mentioned purpose is realized by following technical scheme:
A kind of membrane panel smoking mouth swan neck system, its composition includes: rear pass membrane panel, every a pitch equipped with to the bend pipe outside stove in the middle part of described rear pass membrane panel, described bend pipe forms smoking mouth, equipped with sealing bent plate outside described rear pass membrane panel stove, equipped with sealing plate outside described rear pass membrane panel stove, the described bend pipe on rear pass membrane panel is equipped with wear strip.
The beneficial effects of the utility model:
1. this utility model is before being initiated, the flue-gas temperature of economizer bypass place did not reach the temperature needed for out of stock device originally, at this moment the flue gas at the higher rear pass place extracting high-temperature of flue-gas temperature it is accomplished by, mix with flue gas herein and reach out of stock required flue-gas temperature, by high-temperature flue gas is extracted out by membrane panel to the bend pipe outside stove when this device uses, mix with the low-temperature flue gas of economizer bypass place, make mixed flue-gas temperature can reach the flue-gas temperature needed for denitration, thus the denitration reaction of the flue gas entering denitrification apparatus can be smoothed out, by the NO in flue gas
X
Slough, solve the problem that need to extract flue gas from rear pass membrane panel when equipment for denitrifying flue gas installs economizer bypass additional.
The change of this utility model structure is little, it is simple to site operation;Smoking mouth tube panel be have also been obtained good solution by the problem that flue gas weares and teares simultaneously.
This utility model be in the relevant position of rear pass membrane panel every a pitch pipe to bend pipe outside stove, thus forming smoking mouth, with solve from rear pass membrane panel extract flue gas problem.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the top view of accompanying drawing 1.
Accompanying drawing 3 is the structural representation of this utility model one pipe joint.
Detailed description of the invention:
Embodiment 1:
This utility model composition includes: rear pass membrane panel (1), every a pitch equipped with to the bend pipe (2) outside stove in the middle part of described rear pass membrane panel, described bend pipe forms smoking mouth (3), equipped with sealing bent plate (4) outside described rear pass membrane panel stove, equipped with sealing plate (5) outside described rear pass membrane panel stove, the described bend pipe on rear pass membrane panel is equipped with wear strip (6).
Claims (1)
1. a membrane panel smoking mouth swan neck system, its composition includes: rear pass membrane panel, it is characterized in that: every a pitch equipped with to the bend pipe outside stove in the middle part of described rear pass membrane panel, described bend pipe forms smoking mouth, equipped with sealing bent plate outside described rear pass membrane panel stove, equipped with sealing plate outside described rear pass membrane panel stove, the described bend pipe on rear pass membrane panel is equipped with wear strip.
