Accompanying drawing explanation
Fig. 1 is the structural representation of carrying scraper tail gas purification device of the present utility model.
Detailed description of the invention
Explain detailed description of the invention of the present utility model with reference to the accompanying drawings.
As shown in Figure 1, carrying scraper tail gas purification device of the present utility model, including air inlet pipe 1, catalyst converter 2, interior guide cylinder 3, water bath 5 and exhaustor 10, described catalyst converter 2 is fixedly mounted on the top of described water bath 5, one end of described catalyst converter 2 is connected with described air inlet pipe 1, the other end is connected with described interior guide cylinder 3, and described interior guide cylinder 3 is placed in described water bath 5；The top of described water bath 5 is provided with water inlet 11, and bottom is provided with discharge outlet 7, and water inlet 11 purifies water for injecting in water bath 5, and discharge outlet 7 is used for discharging used purification water；Described exhaustor 10 is connected with described water bath 5, for discharging the tail gas after purifying.
Fill in water bath 5 and purify water, the high-temperature tail gas that scraper electromotor is discharged enters catalyst converter 2 through described air inlet pipe 1, high-temperature gas reacts when through catalyst converter 2, and carbon monoxide, Hydrocarbon, conversion of nitrogen oxides are become carbon dioxide, water, nitrogen and oxygen.It is internal that catalyst is arranged on catalyst converter 2, and catalyst is noble metal catalyst (mainly platinum/Pt, rhodium/Rh, palladium/Pd), and catalyst converter 2 is internal in cellular, and catalyst is attached to surface, reacts with high-temperature tail gas.Alveolate texture is conducive to the contact area increasing tail gas with catalyst.Tail gas enter after catalyst converter 2 oxidation catalysis in guide cylinder 3, gas after catalyst converter 2 oxidation catalysis is transported to purify in the purification water in water bath 5 by interior guide cylinder 3, is removed by the harmful substances such as the nitrogen oxides contained in gas, smokeshade, aldehydes and sulfur dioxide.Purified gas discharges water bath 5 through exhaustor 10.
It is understood that the air inlet of exhaustor 10 is positioned at above the horizontal plane of water bath 5, therefore, exhaustor 10 can be arranged on the top of described water bath 5.Exhaustor 10 can certainly be arranged on the bottom of water bath 5, but air inlet extends to the top of water bath 5, state as shown in Figure 1.
The lower section of described interior guide cylinder 3 is provided with baffle plate 8, described baffle plate 8 is connected by multiple bracers 6 are fixing with the bottom of described interior guide cylinder 3, when preventing gases at high pressure from flowing out from the bottom of interior guide cylinder 3, make the smokeshade being deposited in bottom be stirred, affect clean-up effect.Multiple bracers 6 are used to connect, guide cylinder 3 in making purification water can enter from the interval of baffle plate 8 and interior guide cylinder 3.
For making the gas after catalyst converter 2 oxidation catalysis be fully contacted with purification water in entering water bath 5, described interior guide cylinder 3 periphery is arranged with outer guide cylinder 4, the bottom of described outer guide cylinder 4 is connected by described bracer 6 is fixing with the bottom of described interior guide cylinder 3, and its upper end can be connected by multiple contiguous blocks 12 are fixing with water bath 5.The space that most of gas that the bottom of interior guide cylinder 3 is discharged can enter between described interior guide cylinder 3 and outer guide cylinder 4 flows up, and flows out through the upper end of outer guide cylinder 4.
Purification water in described water bath 5 can be discharged through discharge outlet 7 after use after a while, changes clean water and proceeds to filter, improves clean-up effect.Being provided with dividing plate 9 in described water bath 5, described dividing plate 9 is provided with some permeable holes.Dividing plate 9 will be separated into two spaces in water bath 5, tail gas is purified by the purification water being provided with in the space of described interior guide cylinder 3, and high-temperature tail gas can evaporate the water, and the clean water in another one space can be supplemented by the permeable hole on dividing plate 9.When needing to change purification water the most in use for some time, by discharge outlet 7, used water is discharged, supplement clean water by the permeable hole on dividing plate 9 simultaneously, carrying scraper tail gas purification device of the present utility model can be made to use continuously in the case of non-stop-machine.
Each building block of carrying scraper tail gas purification device of the present utility model can be made of stainless steel, and plays corrosion resistant effect.
As it has been described above, referring to the drawings exemplary embodiments of the present utility model has been described in detail.It is to be appreciated that this utility model is not intended to the restriction making these details constitute this utility model protection domain.In the case of without departing substantially from according to spirit and scope of the present utility model, the change that can be equal to the structure and features of exemplary embodiments or be similar to, these changes will also fall in protection domain determined by this utility model appending claims.
