Open one of them or open easily to adjust oxygen supply amount so as to adjust boiler oil efficiency of combustion, being especially suitable for
Work boiler matching uses, and use more safety is flexibly；In addition by the way that flue is transformed can be to the high-temp waste gas in smokejack
Secondary use is carried out, improves intake air temperature, mitigates the influence to temperature in burner hearth, improves boiler efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of chemical industry boiler air blast corollary apparatus.
Fig. 2 is a kind of structural representation of oxygen-enriched case in chemical industry boiler air blast corollary apparatus.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-2, a kind of chemical industry boiler air blast corollary apparatus, including support case 1 and bearing 2, the support case 1
It is fixedly connected with bearing 2, the upper end of bearing 2 is also fixedly connected with the second air-introduced machine 3, supports in case 1 and is fixedly connected with the He of transfer tube 4
Three-way pipe 5, the one end of transfer tube 4 are fixedly connected with ring flange 6, are entered by carrying out mouth welding flange 6 in air blower with air blower
Air port is connected, and the other end of transfer tube 4 is connected with the mouth of pipe of three-way pipe 5, and helix tube 7, the lower end of helix tube 7 are wound with transfer tube 4
Mouth is connected with the air outlet pipeline of the second air-introduced machine 3, and the upper port of helix tube 7 draws support case 1, and weldering is cut on flue and opens up two
Opening, the upper port of the air inlet of the second air-introduced machine 3 and helix tube 7 is connected with two opening conduits opened up on smoke exhaust pipe respectively
Connect, be that air inlet is heated by the extracting high-temperature flue gas of the second air-introduced machine 3, mitigate cold air and enter in burner hearth to internal temperature
Influence；The another two mouth of pipe of three-way pipe 5 is connected to air inlet pipe 8 and oxygen-enriched case, and the first electricity is respectively equipped with connecting pipe
Magnet valve 9 and second solenoid valve 10, windshield plate 12 is fixedly connected with by connection strap 11 in the air inlet pipe 8, the oxygen-enriched case by
Inner tube 13 and outer container 14 are composed of a fixed connection, and the both ends of outer container 14 are uncovered structure and are fixedly connected with fixation by link 15
Plate 16, the right-hand member of inner tube 13 are fixedly connected with fixed plate 16, and the left end of inner tube 13 is connected through fixed plate 16 with the mouth of pipe of three-way pipe 5,
Some passages 17 are offered on the pipe shaft that inner tube 13 is located in outer container 14, inner tube 13 is coated with oxygen permeable membrane 18, oxygen permeable membrane 18
Mesh pad 19 is coated with, the air being passed through is carried out using the high characteristic of the oxygen permeability of oxygen permeable membrane 18 to propose oxygen processing so that
The oxygen content for blasting air is improved, and oxygen content is improved so as to lift the combustion efficiency of coal by blasting air, and caloric value is big,
And the volatilization of the pernicious gas such as carbon monoxide is few, greatly improves the operational effect of boiler, outer container 14 can shield, avoid
Excessive dust falls on oxygen permeable membrane 18 when hitting damage and idle state, by opening the first magnetic valve 9 or second solenoid valve 10
Select oxygen-enriched air or normal air to enter, imitated by the different coal combustion efficiencies that change of oxygen-supplying amount so as to adjust the work of boiler
The controlling switch of rate, the first magnetic valve 9 and second solenoid valve 10 on boiler console, facilitates fireman's control, except list
Outside solely opening, two magnetic valves can be also opened simultaneously, and now air inlet is oxygen-enriched air and the mixture of normal air, and oxygen content is situated between
Among both, third gear regulation, use is more flexible, because oxygen permeable membrane 18 can increase intake resistance to a certain extent, passes through air inlet
The windshield plate 12 set in pipe increases windage, and making air inlet pipe 8, identical with the windage of oxygen-enriched case (the size type selecting of windshield plate 12 is because of root
Pass through experimental selection according to the big ting model difference of oxygen-enriched case), two kinds of the uniform of air so can be achieved and blast, in addition, can also incite somebody to action
First magnetic valve 9 and second solenoid valve 10 are replaced with common gate valve, and the opening and closing amount of manual regulation gate valve may be such that two kinds of air
Proportioning is more flexible, but needs fireman's execute-in-place if this setting and can not directly be operated in console, cumbersome,
Can voluntarily selection operation mode as needed,
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.
