Specific embodiment
The present invention is further described with reference to specific embodiment：
As shown in figure 1, a kind of high temperature membrane dedusting component, including body 1, demarcation strip 2 and high temperature membrane tube 3；Demarcation strip 2 sets
It is placed in body 1, body 1 is divided into cavity one and cavity two, through hole is provided with demarcation strip 2, high temperature membrane tube is arranged on
In through hole, the main part of high temperature membrane tube 3 is arranged in cavity one, and the openend of high temperature membrane tube 3 is arranged in cavity two, due to
Flue gas is entered by cavity one, to be filtered by high temperature membrane tube 3 and removed flue gas after being entered in cavity two by the openend of high temperature membrane tube 3
In the grit that mixes, so cavity one is referred to as into dust and gas chamber 4, cavity two is referred to as net air cavity 5, during work, flue gas is advanced
Enter to dust and gas chamber 4, high temperature membrane tube 3 is hollow, some nano level through holes are provided with the wall of side, such flue gas can be by logical
Hole is entered into high temperature membrane tube 3, then is entered in net air cavity 5 by the openend of high temperature membrane tube 3, and the dust in flue gas cannot pass through
Through hole, is isolated in dust and gas chamber 4, so as to serve the effect to high temperature fume dust removal, it is preferred that set on the side wall of body 1
An inspection socket 7 is equipped with, closure 8 is provided with inspection socket 7, when high temperature membrane dedusting component internal breaks down, will can sealed
Lid 8 is opened, and maintenance personal is entered into by inspection socket 7 and repaired in body 1.Preferably, the openend diameter of high temperature membrane tube 3 is big
In the diameter of the main body section of high temperature membrane tube 3, so, can be set by the way that the main body section of high temperature membrane tube 3 is inserted on demarcation strip 2
The mode of through hole high temperature membrane tube 3 is conveniently fixed on demarcation strip.
As shown in Figure 2 to Figure 3, is provided with to support the support member 6 of demarcation strip 2 in body 1, it is preferred that support member 6 is
Vaporizing cooling pipe, is provided with cooling medium such as water or cooling gas in Vaporizing cooling pipe, the two ends of Vaporizing cooling pipe are respectively provided with
Outside the side wall of body 1, Vaporizing cooling pipe is arranged on the side of through hole in dust and gas chamber.
Preferably, demarcation strip 2 is stepped, and through hole thereon is arranged on the step of demarcation strip 2, when high temperature membrane tube is many
During root, each through hole for setting high temperature membrane tube is distributed along the length direction of step, high temperature membrane tube 3 is arranged along the length direction of step
Row, each step sets many high temperature membrane tubes can have many high temperature membranes of longitudinal arrangement on the sustained height in body 1
Pipe 3, so as to increase the sum that high temperature membrane tube is set in body, increases deduster filter area, improves the filter effect to flue gas,
Preferably, the step surface 20 of demarcation strip 2 is obliquely installed with the axis of body 1, and the axis of high temperature membrane tube 3 is vertical with step surface 20 to be set
Put and make the openend of high temperature membrane tube to set up, inclined between the axis for thus making the axis of high temperature membrane tube 3 and body 1 and set
Put, so that high temperature membrane tube is inclined in body 1, high temperature membrane tube 3 is inclined in body one, can be in body one
Internal diameter is constant, step width and angle of inclination it is constant in the case of increase the quantity of step in every section of body one so that further
Increase the setting number of plies of the high temperature membrane tube in body one, can further improve the setting total amount of high temperature membrane tube 3, improve to flue gas
Filter effect and filter area.More useful effect is that axis and the axis of body one of high temperature membrane tube 3 are obliquely installed, and work as height
When the axis vertical of warm membrane tube 3 is set, the axis of body one is inclined to set state, and the superposition of multistage body one can so set
Put, and in the case where the height of whole deduster is not increased, the length of whole deduster body 1 can be extended, improve dedusting effect
Really.Now, the axis direction of Vaporizing cooling pipe is set along the length direction of step, when the high temperature membrane on each step surface 20
When pipe 3 has multiple, that is, the length direction of each step platform, when setting multiple through hole, Vaporizing cooling pipe is located at each through hole
Side, makes each through hole be distributed along the length direction of Vaporizing cooling pipe.
Can be lowered the temperature to entering into the flue gas in dust and gas chamber 4 by Vaporizing cooling pipe, it is to avoid due to the temperature mistake of flue gas
It is high and body 1 is deformed the inconvenience for causing to use, can also avoid high temperature failure high temperature membrane tube.Preferably, cold water pipe is two, two
Root cold water pipe is respectively arranged at the both sides of rows of high temperature membrane tube 3.Under the support of Vaporizing cooling pipe, high temperature membrane tube 3 is by dividing
Dividing plate 2 is fixedly installed in body 1.
As shown in 4 figures, the openend top of each high temperature membrane tube 3 is provided with nozzle 21, and nozzle 21 is connected with tracheae 22,
The openend to high temperature membrane tube 3 is rectified in the opening of nozzle 21, and after filtering for a long time, the dust in flue gas can hang over or fall into high temperature
On the through hole of membrane tube 3, by the blow gas of nozzle 21, blowback is played a part of to dust, flying dust is departed from the logical of high temperature membrane tube 3
Hole, it is to avoid high temperature membrane tube 3 is blocked, it is preferred that an inflator gas bag 23 is connected by the inlet end of tracheae 22, tracheae is arranged at pipe
Internal part is provided with some gas outlets, and a nozzle 21 is connected at each gas outlet, and gas bag is connected to tracheae by inflator
Interior insufflation gas, gas enters nozzle through gas bag by the gas outlet of tracheae, then is sprayed by nozzle, so as to be played to high temperature membrane tube 3
The effect of blowback, it is preferred that the gas that inflator is filled with when fuel gas is filtered is inert gas.
As shown in Figure 2 and Figure 5, present invention also offers a kind of high temperature film dust-remover, including smoke-intake pipe 9, pipe 10 with
And the above-mentioned high temperature membrane dedusting component of ash bucket 14 and at least one；Smoke-intake pipe 9 is arranged at the upper end in dust and gas chamber 4 or middle and dust and gas
Chamber is connected, and the lower end or centre that ash bucket 14 is arranged at dust and gas chamber 4 are connected with dust and gas chamber, and pipe 10 is arranged at net air cavity 5
Lower end be connected with net air cavity, flue gas is entered into dust and gas chamber 4 by smoke-intake pipe 9, is entered into after high temperature membrane tube 3 is filtered net
In air cavity 5, the dust under filtering is fallen into ash bucket 14 and is collected, and the flue gas after filtering is finally discharged by pipe 10, preferably
, the upper end of net air cavity 5 is sealed by end cap, because the flue gas after dedusting will also be further processed, by end cap
It is avoided that the flue gas after dedusting is directly discharged in air, it is preferred that the high temperature film dust-remover that the present embodiment is provided includes N number of high
Warm film dedusting component, when high temperature membrane dedusting component is connected with high temperature membrane dedusting component, the dust and gas of the high temperature membrane dedusting component of top
