Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment one.
As shown in Figure 1, a kind of waste gas purification apparatus for making fish meal of the present utility model, comprise the seal case 1 for holding purified solution, described seal case 1 inside is provided with Liqiud-gas mixing device 2, described Liqiud-gas mixing device 2 is connected with air inlet pipe 21, and described seal case 1 is connected with escape pipe 22; Described escape pipe 22 is connected with spray cleaning device 3, and the gas outlet of described spray cleaning device 3 is connected with air-introduced machine 4; Described Liqiud-gas mixing device 2 comprising hybrid channel 23, stirring power shaft 24, for mixing the first impeller 25, second impeller 26 and trilobed wheel 27 of seal case 1 solution and air inlet pipe 21 gas, described first impeller 25, second impeller 26 and trilobed wheel 27 sequentially distribute from lower to upper, described first impeller 25, second impeller 26 and trilobed wheel 27 are all positioned at the inside of hybrid channel 23 and are serially connected with stirring power shaft 24, and described stirring power shaft 24 passes seal case 1 and is connected with outside PTO 28; Seal case 1 is fixed in described hybrid channel 23, and described air inlet pipe 21 is communicated in described hybrid channel 23, and described first impeller 25 is positioned at above the gas outlet of air inlet pipe 21.
According to the situation absorbing waste gas, before use, configure corresponding purified solution, the purified solution configured is poured in seal case 1, and by hybrid channel 23 submergence.Produce water smoke time hybrid channel 23 submergence can prevent impeller from stirring by purified solution, and be prevent purified gas from taking away large quantity of moisture.PTO 28 drives stirring power shaft 24 to rotate, stir power shaft 24 drives the first impeller 25, second impeller 26 and trilobed wheel 27 to rotate simultaneously, and the solution can drawn when the first impeller 25 rotates in seal case 1 carries out cycle operation in seal case 1.Waste gas is arranged in hybrid channel 23 by air inlet pipe 21, at the first impeller 25 rotated and the second impeller 26, form liquid-gas Mixed Zone between trilobed wheel 27, after waste gas enters this region, fully mix with the solution configured, solution fully absorbs the harmful substance in waste gas, maximum purifying exhaust air.Cleaned gas continues toward rising, and gas enters escape pipe 22 through after liquid level, enters spray cleaning device 3 by escape pipe 22, spray cleaning device 3 pairs of gases do further purification, the clean-up effect of lift gas greatly, whole process so circulates, and waste gas is constantly purified.Purified gas is discharged under the effect of air-introduced machine 4.
Particularly, described spray cleaning device 3 comprises purification pipeline 31, and the top of described purification pipeline 31 is connected with some spray heads 32, and the below of described purification pipeline 31 is connected with some devil liquor recovery pipes 33.Spray head 32 carries out the sprinkling of solution in purification pipeline 31, waste gas under the effect of air-introduced machine 4 purification pipeline 31 inside condensation Bottomhole pressure, harmful substance in waste gas does further purified treatment to waste gas, clean-up effect of greatly deducting a percentage under being drenched by the chilled aqueous solution that spray head 32 sprays out.
As preferably, this purifier also comprises scavenging solution storage box 5, described spray head 32 is connected with scavenging solution storage box 5 by pipeline, the top of described seal case 1 offers inlet, described inlet is connected with input duct 11, and described inlet is connected with scavenging solution storage box 5 by input duct 11; The bottom of described seal case 1 offers liquid outlet, and described liquid outlet is connected with fluid pipeline 12; Described devil liquor recovery pipe 33 is connected with fluid pipeline 12.Spray cleaning device 3 and Liqiud-gas mixing device 2 can use the purified solution in scavenging solution storage box 5 jointly, simplification device structure, save the parking space of solution.
As preferably, described input duct 11 is provided with switching valve body 13 with fluid pipeline 12.This switching valve body 13 can control input duct 11 and the turnover of fluid pipeline 12 solution, is convenient to the replacing of purified solution in seal case 1.
Embodiment two.
As shown in Figure 2, the difference of the present embodiment and embodiment one is, the bottom inside of described hybrid channel 23 is provided with waste gas cavity 231; Described air inlet pipe 21 is communicated in described waste gas cavity 231, and described waste gas cavity 231 offers venthole, and described venthole is positioned at the below of the first impeller 25.The waste gas that the waste gas cavity 231 of the present embodiment makes air inlet pipe 21 enter effectively is spread, and the first impeller 25 can draw exhaust uniformly, and waste gas is mixed with solution more fully.
Described venthole is provided with several, and several ventholes are opened in the upper surface of waste gas cavity 231, and described first impeller 25 is positioned at the top of waste gas cavity 231 upper surface.First impeller 25 when rotated, forms one suction, and venthole is positioned at below it, and waste gas cavity 231 can be sucked out smoothly.
The top of described hybrid channel 23 is provided with the current baffle plate 29 for stopping current; Delivery port is left between current baffle plate 29 and hybrid channel 23.When the impeller in hybrid channel 23 stirs time, can upwards produce one current, after making gas-vapor mix, directly go out liquid level, cause the Purge gas of discharging outward to take away a large amount of moisture content fog.In order to avoid above-mentioned situation, current baffle plate 29 is set above hybrid channel 23, current after gas-vapor mix are stopped thus makes flow rate of water flow slack-off, when current flow out from delivery port, gas is separated in the process automatically, prevents the current of gas-vapor mix directly to go out liquid level and makes purified gas take away large quantity of moisture.
The remainder of the present embodiment is identical with embodiment one, repeats no more here.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
