Abstract
The utility model relates to a zero-leakage seal valve. The zero-leakage seal valve comprises an air inlet pipe, a linkage air valve, a wind shielding door valve body and a linkage device, the air inlet pipe is connected with the linkage air valve, the other end of the air inlet pipe is connected with the tail portion of a dust collector, wind shielding door page sheets are arranged on the wind shielding door valve body, and the wind shielding door page sheets and the linkage air valve are connected with the linkage device. Transmission of an air cylinder is achieved through the linkage device, so that the wind shielding door page sheets are driven to rotate and the linkage air valve is driven to be opened and closed. An air fan is arranged on the air inlet pipe. The zero-leakage seal valve has the advantages that based on the air seal mode, smoke media are prevented from passing through a seal shield which is composed of the wind shielding door valve body and the wind shielding door page sheets, and full seal of a wind shielding door is guaranteed; meanwhile, hot gas of the tail portion of the dust collector is made to directly enter the air inlet pipe, clean smoke of the tail portion of the dust collector is effectively utilized, and therefore energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of zero leakage seal valve, relates in particular to the seal valve of a kind of utilization take gas as auxiliary seal.
Background technique
At present, in the dedusting field, on some large-scale sack cleaners, by-pass valve is installed, by-pass valve adopts the zero leakage seal valve more, and this seal valve adopts multiple mechanical seal chip architecture sealing, and this sealing means is owing to being the metal rigidity sealing, so can't reach actual zero leakage, can there be certain leakage phenomenon in what, and the flue dust leakage can cause environmental pollution, so need a kind of device can realize real zero leakage.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of zero leakage seal valve, realizes the zero leakage of flue dust, reduces the discharging of flue dust.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of zero leakage seal valve, comprise air intake pipe, interlock air-valve, baffle door valve body, linkage, air intake pipe is connected with the interlock air-valve, the air intake pipe the other end is connected with the deduster afterbody, the wind blocking door valve body is provided with the wind blocking door hinge, and wind blocking door hinge, interlock air-valve are connected with linkage, and cylinder is by the linkage transmission, drive the rotation of wind blocking door hinge and interlock air-valve switch, described air intake pipe is provided with blower fan.
Compared with prior art, the beneficial effects of the utility model are:
Mode by gas seal makes flue gas medium by the sealing barrier that is comprised of baffle door valve body, baffle door hinge, guarantee baffle door 100% sealing; Simultaneously, also the hot gas of deduster afterbody directly can be accessed air intake pipe, effectively utilize the clean flue gas of deduster afterbody, energy efficient.

Fig. 2 is stereogram of the present utility model.
In figure: 1-air intake pipe 2-blower fan 3-interlock air-valve 4-linkage 5-barge board valve body 6-wind blocking door hinge 7-cylinder.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, Fig. 2, a kind of zero leakage seal valve, comprise air intake pipe 1, interlock air-valve 3, baffle door valve body 5, linkage 4, air intake pipe 1 is connected with interlock air-valve 5, and air intake pipe 1 the other end is connected with the deduster afterbody, and wind blocking door valve body 5 is provided with wind blocking door hinge 6, wind blocking door hinge 6, interlock air-valve 3 are connected with linkage 4, cylinder 7 drives 6 rotations of wind blocking door hinge and interlock air-valve 3 switches by linkage 4 transmissions, and described air intake pipe 1 is provided with blower fan 2.
When wind blocking door hinge 6 is opened, interlock air-valve 3 cuts out, when wind blocking door hinge 6 is closed, interlock air-valve 3 is opened, this moment, sealing air directly entered through air intake pipe 1, blow through blower fan 2, enter interlock air-valve 3, because sealing air pressure ratio flue gas medium pressure is high, flue gas medium can't be passed through by barge board hinge 6, the sealing barrier that wind blocking door valve body 5 and sealing air form is guaranteed baffle door 100% sealing.
Sealing air need to heat it before entering air intake pipe 1, the generation of Antidewing phenomenon, and for example the power of the heating equipment of certain seal valve is 30KW/h, because this equipment needs continuous operation, be exactly 720KW 24 hours every days, calculated by 360 days, and be exactly 259200KW in 1 year.Be energy saving, lengthen suction tude 1, directly get net heat gas (gas temperature of general deduster afterbody can reach 130 ℃) from the afterbody of deduster, valve body is sealed.So namely prevent the generation of dewfall phenomenon, saved again the energy, improved economic benefit.
The utility model makes flue gas medium by the sealing barrier that is comprised of baffle door valve body, baffle door hinge, guarantee baffle door 100% sealing by the mode of gas seal; Simultaneously, also the hot gas of deduster afterbody directly can be accessed air intake pipe, effectively utilize the clean flue gas of deduster afterbody, energy efficient.
