Description
Technical field
The present invention relates to a kind of environment-friendlynegative negative pressure boiler.
Background technology
Boiler needs burning fuel, and when burning fuel, in the presence of high temperature, nitrogen and oxygen in air are easily sent out
Raw combination reaction, the oxynitrides that formation is polluted, and because the burn incompletely of fuel can produce a substantial amounts of oxidation
Carbon.Existing boiler is all difficult to solve this problem, because most cheap oxidant is exactly air, but nitrogen content in air is again
It is very high.In order to reduce oxynitrides, tail gas is allowed to meet discharge standard, many boiler for producing commercial cities have to reduce boiler
Fuel feed speed, lay multiple burning points, allow fuel to try one's best the oxygen exhausted in air, to reduce the product of oxynitrides
It is raw, but this can cause the efficiency of boiler to substantially reduce again.
Boiler needs constantly to supplement water constantly to produce steam, water to could be stored in water tank.Because the need of energy-conservation
Will, often recovered steam is condensed into temperature water storage higher in water tank, for the case of the water tank of boiler to present boiler
Interior pressure can change with the temperature change of water, existing water tank in order to avoid tank pressure it is excessive and under tank seal performance
Drop, leak, the situation of fried case occur, and existing water tank is all have normally opened steam vent, constant to ensure the pressure in water tank.But
It is loss that normally opened steam vent can cause heat, this just unusual not energy-conserving and environment-protective.
The content of the invention

Specific embodiment
The technique effect of design of the invention, concrete structure and generation is carried out clearly below with reference to embodiment and accompanying drawing
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/annexations, not singly refer to that component directly connects, and refer to that can be added deduct by adding according to specific implementation situation
Lack couple auxiliary to constitute more excellent draw bail.Each technical characteristic in the present invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
Referring to Figures 1 and 2, this is flabellum embodiment of the invention, specifically：
A kind of environment-friendlynegative negative pressure boiler, including the boiler body of combustion chamber 1 is provided with, combustion chamber 1 is provided with bleeding point 2, on bleeding point 2
It is provided with air-extractor 21, combustion chamber 1 and is provided with combustion platform 3, also including return-air duct, the entrance of return-air duct is located at air-extractor
21 inner side, the outlet of return-air duct is provided with the side in combustion platform 3, and blast apparatus 4 is provided with return-air duct.As negative pressure pot
Stove, the mode of entrance of air is the pressure for utilizing negative pressure, therefore bleeding point discharge is waste gas, because return-air duct can be by waste gas
It is withdrawn near combustion platform, allows waste gas to participate in burning, oxynitrides and carbon monoxide, these oxynitrides is contained in waste gas
Deoxidation reaction is carried out as oxidant and fuel in combustion chamber again, nitrogen is ultimately generated, carbon monoxide will join as fuel
With burning, it is achieved thereby that reduce pernicious gas discharge.And waste gas plays the role of to drop oxygen, can reduce the play of the burning of fuel
Strong degree, the central temperature of such fuel can just be reduced, and this is also beneficial to suppress the production of oxynitrides.
In order to waste gas can be easily entered in return-air duct, the present embodiment also includes pump-line, and the pumping sets
Standby 21 are located in pump-line, and the entrance of return-air duct is located on the tube wall of pump-line.
For ease of the air quantity of regulation brattice outlet, return air channel is provided with electrically-controlled valve or hand-operated valve.
Boiler is the efficiency for lifting boiler, is connected with the tank body for being provided with water storage cavity on boiler body, water storage cavity it is upper
Portion is provided with relief tube 30, and the both sides top that relief tube 30 has downward curved segment, lower horizontal section is equipped with ventilation section, the two ventilations section
Connected with lower horizontal section in the both sides of lower horizontal section respectively, a ventilation section is connected with storage tank, another ventilation section is in communication with the outside.
When using, water is added in lower horizontal section, sealing is played a part of to relief tube, when the air pressure in water storage cavity rises, air pressure meeting
The current direction of lower horizontal section and the extraneous ventilation section being connected are forced, until the original water in lower horizontal section flows completely out ventilation section so that
In water storage cavity and atmosphere, it is ensured that the safety of tank body, because the coolant-temperature gage in water storage cavity is higher, so in water storage cavity
Humidity is larger, and after the water of lower horizontal section is emptied, the vapor in water storage cavity passes through that during relief tube water can be condensed on tube wall, and
Condensed water can be also formed after the air for running into outside, due to necessarily there is turning between lower horizontal section and ventilation section, so condensed water
It is not easy to discharge relief tube, so lower horizontal section can slowly be full of condensed water again, the sealing of relief tube is realized again.Relief tube it is skilful
Wonderful setting, it is ensured that tank body safety, pressure are constant.Relief tube simple structure, with low cost, its life-span is also significantly larger than
Mechanically, the relief valve of electronic type, and mechanical and electronic type relief valve once failure, it will cause huge damage
Lose, once because water tank is blown, boiler can not in time supplement water, it is easy to there is fire and even explode.Air deflector 20 can be by
The inwall of water storage cavity is oriented into the water in water storage cavity, allows the water to be slid at leisure along the inwall of water storage cavity, it is to avoid existing water tank
Noise during moisturizing.
It is in inverted π fonts that the relief tube 30 of the present embodiment is overall, and lower horizontal section is u-shaped, two upper end difference of lower horizontal section
Prolong to form ventilation section toward left and right putting down, by the whole height or area of section that adjust relief tube itself, it is possible to achieve different pressures
Scope is precisely controlled.
In order to allow people to can know that the water level in water storage cavity, liquid level tube is provided with water storage cavity, the opening in liquid level tube is located at
The top of body, called putting-into-type liquid level meter is provided with liquid level tube 40 under water.The setting of liquid level tube, can avoid the fluctuation of the water surface and lead
The problem for causing measurement inaccurate.
For the ease of connection, the top of water inlet 110 is provided with flange.
In order to prevent the problem of local ponding, the bottom of water storage cavity is back taper, while the water storage cavity of back taper can be
During cleaning tank body, the water in water storage cavity is emptied to greatest extent.
In order to allow tank body uniform force, water storage cavity is integrally in cylinder.
Better embodiment of the invention is illustrated above, but the present invention is not limited to the embodiment,
