A kind of boiler exhaust gas treatment facilities and the boiler using the structure
Technical field
The utility model is related to a kind of boiler exhaust gas treatment facilities and the boiler using the structure.
Background technology
Boiler needs burning fuel, when burning fuel, in the presence of high temperature, and the nitrogen and oxygen in air are easily sent out
Raw combination reaction, forms the oxynitrides 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 the 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 production of oxynitrides
It is raw, but this can cause the efficiency of boiler to substantially reduce again.Moreover, despite so, still have substantial amounts of nitrogen oxides and
Carbon monoxide is produced, and these gases are very serious to atmosphere pollution.
Boiler needs constantly to supplement water constantly to produce steam, and water could be stored in water tank.Because the need of energy-conservation
Will, often recovered steam is condensed into the higher water of temperature and is stored in water tank for present boiler, the case for the water tank of boiler
Interior pressure can change with the temperature change of dampening, 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 to have normally opened steam vent, to ensure that the pressure in water tank is constant.But
It is that normally opened steam vent can cause the loss of heat, this just unusual not energy-conserving and environment-protective.

Fig. 2 is the structural representation of tank body of the present utility model.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to constitute more excellent draw bail.Each technology in the utility model is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
Referring to Figures 1 and 2, this is embodiment of the present utility model, specifically:
A kind of boiler, including boiler body, the blast pipe 1 for the horizontal setting being vented to the right, blast pipe 1 are located at boiler body
Exhaust outlet on, in addition to for being passed through the purification pipe 2 of oxidizing gas, the outlet of purification pipe 2 is located at the inner tubal wall of blast pipe 1
On, the angle of the outgassing direction of blast pipe 1 and the outgassing direction of purification pipe 2 is at an acute angle.In use, by blast pipe and boiler body
Exhaust outlet be connected, then toward purification pipe be passed through the oxidizing gases such as air, oxygen, due to boiler produce tail gas temperature it is non-
Normal height, so oxidizing gas can react with carbon monoxide and oxynitrides, ultimately generates carbon dioxide and nitrogen, so that
Reduce the discharge of tail gas.And the angle α of the outgassing direction of the outgassing direction due to blast pipe and purification pipe is at an acute angle, so oxygen
Changing gas can be sufficiently mixed with tail gas.The utility model can not only be used for new boiler, moreover it is possible to which old boiler is transformed.
In order to improve mixing efficiency, blast pipe 1 and the angle for purifying pipe 2 are 30 ° ~ 40 °.
Because the speed of exhaust emissions is quickly, in order to avoid tail gas is back in purification pipe, purification pipe 2 is provided with air blast
Machine.
Air is used as most cheap oxidant, the outlet of the purification pipe 2 of the present embodiment and atmosphere.
Boiler is the efficiency of lifting boiler, is connected with the tank body provided with water storage cavity on boiler body, water storage cavity it is upper
Portion is provided with relief tube 30, and relief tube 30, which has, is equipped with ventilation section above downward curved segment, the both sides of lower horizontal section, the two ventilations section
Connected respectively in the both sides of lower horizontal section with lower horizontal section, a ventilation section is connected with storage tank, another ventilation section is in communication with the outside.
In use, adding water in lower horizontal section, sealed effect is played to relief tube, when the air pressure in water storage cavity rises, air pressure meeting
The ventilation section that the current direction and the external world for forcing lower horizontal section are connected, 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, after the water emptying of lower horizontal section, the vapor in water storage cavity by the way that water can be condensed into during relief tube 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
It is wonderful to set, it is ensured that tank body safety, pressure are constant.Relief tube is simple in construction, with low cost, and its life-span is also significantly larger than
Mechanically, the relief valve of electronic type, and the relief valve once failure of mechanical and electronic type, it will cause huge damage
Lose, once because water tank is blown, boiler can not supplement water in time, it is easy to there is fire or even blast.Air deflector 20 can be by
The inwall of water storage cavity is oriented into the water in water storage cavity, allows inwall of the water along water storage cavity to slide at leisure, it is to avoid existing water tank
Noise during moisturizing.
The overall relief tube 30 of the present embodiment is in inverted π fonts, and lower horizontal section is u-shaped, two upper end difference of lower horizontal section
Prolong to form ventilation section toward left and right put 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 can know that, the opening being provided with the water level in water storage cavity, water storage cavity in liquid level tube, liquid level tube is located at
Called putting-into-type liquid level meter is provided with the top of body under water, liquid level tube 40.The setting of liquid level tube, can avoid the fluctuation of the water surface and lead
Cause the problem of measurement is inaccurate.
For the ease of connection, the top of water inlet 110 is provided with flange.
The problem of in order to prevent local ponding, the bottom of water storage cavity is back taper, while the water storage cavity of back taper can be
When clearing up 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 present utility model is illustrated above, but the utility model be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
