Detailed description of the invention
For the ease of clear understanding technical scheme of the present invention, be described in detail below in conjunction with embodiment.
An embodiment provides a kind of oxyhydrogen generator fireproof tempering device, as shown in Figure 1, described oxyhydrogen generator fireproof tempering device comprises tank body 1, in the cavity of described tank body 1, be provided with isolated tube 2, the cavity of tank body 1 to be divided into the separate cavities 3 and exocoel 4 that are positioned at isolated tube 2;
Be provided with hypomere on the top of described tank body 1 and be suspended on unsettled pipe 5 in separate cavities 3, the epimere of described unsettled pipe 5 is provided with the gas outlet 6 being exposed to tank body outside;
The bottom of described tank body 1 is provided with the air inlet 7 being communicated to exocoel 4.
Because combustion of hydrogen speed is fast, penetration capacity is strong, and the anti-backfire mode of fluid-tight that utilizes merely of the prior art is difficult to reach anti-backfire effect, even if increase liquid height, non-return effect is still not obvious, easily occurs because tank body lost efficacy and causes generator to damage.And the oxyhydrogen generator fireproof tempering device that the present embodiment provides.When oxyhydrogen generator works, air inlet is connected with oxyhydrogen generator, gas outlet is connected with gas use side, the gas that oxyhydrogen generator produces enters into exocoel 4 from the air inlet of tank body 1 bottom, the characteristic of the liquid washing medium 8 utilizing specific gravity of gas to be lighter than to install additional in tank body 1, gas washs rear arrival tank body 1 top by washing medium 8, the continuous injection of gas increases tank body 1 head gas pressure, washing medium 8 is pressed in unsettled pipe 5, when washing medium 8 liquid level and unsettled pipe 5 are concordant bottom, gas is flowed out by unsettled pipe 5, reach smooth working state.When there is tempering, gas explosion in unsettled pipe 5, according to the deflagration behavior of hydrogen, instantaneous expansion in unsettled pipe, then negative pressure is formed rapidly, to make in unsettled pipe 5 after washing medium 8 moment outer row resorption again, thus the liquid height in unsettled pipe 5 increases, being communicated with of the gas produced with oxyhydrogen generator with the flame that strile-backs intercepted in unsettled pipe 5, play point effect deadening envelope, it ensure that effective obstruct of the gas that strile-back flame and oxyhydrogen generator produce by the fluctuation of liquid height, improves anti-backfire effect.
In the present embodiment, preferably, described isolated tube 2 upwards extends bottom tank body 1, and top not with tank body 1 top contact, to form gas channel between isolated tube 2 top and tank body 1 top.
Owing to being provided with isolated tube 2, the gas that oxygen hydrogen generator produces is due to the buffer action of isolated tube 2, enter into the space of tank body 1 ullage, during to make the gas pressure in the space of ullage in tank body 1 enough large, gas just can enter into separate cavities 3, then unsettled pipe 5 is entered into, and directly can not enter into unsettled pipe 5 from tank body 1, utilize liquid washing medium liquid fluctuating under pressure in the fluid-tight of liquid washing medium in exocoel 4 and separate cavities 3 to realize effectively blocking anti-backfire object.
The set-up mode of above-mentioned isolated tube 2 is one more preferably set-up mode, when specifically arranging, isolated tube 2 also upwards can not extend bottom tank body 1, such as upwards extend in the middle part of tank body 1, also buffer action can be realized, but now needing separately to be fixed frame is fixed in tank body 1 by isolated tube 2, and this kind of mode is not as good as the firm safety of aforementioned set-up mode.
In order to make unsettled pipe 5, there is sufficiently long length, to make its inner liquid that can hold enough high liquid level when anti-backfire, and also make the gas outlet 7 be located thereon conveniently be connected with gas use side, one section of described unsettled pipe 5 is positioned at outside tank body 1, and the position that contacts with tank body 1 is welded with tank body 1, to make its structure safety and firmness more.
Be connected convenient in order to gas outlet 7 is convenient with gas use side, described gas outlet 7 is preferably disposed on the top of the outer unsettled pipe 5 of tank body 1.
In the present embodiment, preferably, the central axis of described unsettled pipe 5 and tank body 1 central axis point-blank, and the middle part of described unsettled pipe 5 and tank body 1 welded top.Setting like this, its structure is more reasonable, compact.
In order to make the liquid level in separate cavities 3 consistent with the liquid level in exocoel 4, the bottom of described isolated tube 5 is provided with the via 9 be communicated with exocoel 4 by separate cavities 3.Setting like this, tank body 1 arranges finder, by observing the liquid level in exocoel 4, just can learn the liquid level in separate cavities 3, facilitating the setting of finder.
Oxyhydrogen generator fireproof tempering device in the present embodiment in use, can add washing medium by described whole tank body, and described washing medium liquid level also can be made to be positioned at below unsettled pipe 5 hypomere.
Conveniently in tank body 1, inject washing medium 8, described tank body 1 is provided with liquid injection hole 10.Described liquid injection hole 10 is preferably disposed on tank body 1 top.
For the ease of observing the liquid level of the washing medium 8 in tank body 1, described tank body 1 is provided with transparent liquid level peep hole 11.
Described liquid level peep hole 11 can be a bar hole extended along tank body 1 vertical direction, also can comprise two peep holes one on the other, to observe the liquid level of the washing medium 8 in tank body 1.When specifically arranging, be not limited thereto two kinds of set-up modes.
In order to make gas more easily enter into unsettled pipe 5, time also in order to there is detonation in unsettled pipe 5, washing medium 8 is drawn back in unsettled pipe 5 more fast, and the bottom of described unsettled pipe 5 is preferably in falling toroidal.
Preferably, in order to control the turnover of gas in tank body 1, described air inlet 7 and gas outlet 6 are provided with valve or seal cover, to realize when not being connected with oxyhydrogen generator and gas use side sealing.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme, it is expanded and extends and is within its claims protection domain.
