It should be noted that when element is referred to as " being fixedly arranged on " another element, it can be directly on another element Or there may also be element placed in the middle.When an element is considered as " connection " another element, it can be directly connected to To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ", " right side " and similar statement are for illustrative purposes only.

Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to the technology of the utility model The normally understood implication of technical staff in domain is identical.It is simply in the term used in the description of the utility model herein The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include The arbitrary and all combination of one or more relevant Listed Items.

Referring to Fig. 1, a kind of dehydrator 100 provided in one embodiment of the utility model, including cylinder 10, the cylinder It is equipped with the first dewatering elements 11 in 10, the top of the cylinder 10 is equipped with gas outlet 101, on the side wall of the bottom of the cylinder 10 Equipped with the air inlet 102 being connected with a Venturi tube, the cylinder 10 is from the position of first dewatering elements 11 to the cylinder 10 top is set to several tapering type structures 12, and water fender 13, the water blocking are equipped between adjacent two tapering type structures The free terminal of plate 13 is obliquely installed.

Specifically, in the present embodiment, the middle part of the cylinder 10 of the free terminal of the water fender 13 downward tilts. The purpose that the water fender 13 is so set is to avoid the moisture by first dewatering elements 11 abjection from being expelled directly out, and is avoided There is " rainy " situation in the diffusing chimney, so as to improve dehydration efficiency.

Specifically, in the present embodiment, first dewatering elements 11 are eddy flow dehydrator, are equipped with the eddy flow dehydrator 10~20 blades, the range of tilt angles of each blade is 20 °~50 °.It should be understood that in other embodiments, The number of the blade is not limited thereto, and can set several according to the actual needs of exhaust gas volumn.

It should be understood that in other embodiments, first dewatering elements 11 are at least eddy flow dehydrator or silk screen takes off One kind among hydrophone.

The second dewatering elements 14 being connected with the air inlet 102 are equipped with referring again to Fig. 1, in the cylinder 10, it is described Second dewatering elements 14 include positioned at first dewatering elements 11 lower section dehydration body 141, and with the dehydration body The air inlet pipe 142 of 141 connections, the free terminal of the air inlet pipe 142 are connected with the air inlet 102.

Referring to Fig. 2, the air inlet pipe 142 and the outer surface of the dehydration body 141 are tangentially connected.The air inlet pipe 142 tangentially connected purposes be in order to enable flue gas can produce centrifugal force when entering in the dehydration body 141, it is small in flue gas Drop can carry out preliminary hydro-extraction under the influence of centrifugal force.

Referring again to Fig. 1, the side wall of the cylinder 10 is equipped with two layers of sprinkling element 15, each layer sprinkling element 15 Between first dewatering elements 11 and second dewatering elements 14, and the sprinkling end of the sprinkling element 15 is located at The middle part of the cylinder 10.Nozzle in the sprinkling end of the sprinkling element 15 is set towards the bottom of the cylinder 10, and Sprayed using clean circulating water.Remaining dust in flue gas is further mixed, hit, is solidifying by the sprinkling element 15 with clean circulating water It is poly- so that the dust content in flue gas further reduces.

It should be understood that in other embodiments, the number of plies of the sprinkling element 15 is not limited thereto, can be according to cigarette If the actual needs of tolerance sets dried layer.

Referring to Fig. 3, the spraying range of each layer sprinkling element 15 is not less than 10 diameter of cylinder, and last layer The spraying range of the sprinkling element 15 covers the spraying range of next layer sprinkling element 15.So so that described in each layer Flue gas can be relaundered for sprinkling element 15 and the dedusting that cools down.

In the utility model, the flue gas by Venturi tube purification tangentially enters in second dewatering elements 14, is centrifuging Under the action of power, slough part water in dust removal, into the fume-dehydrating in second dewatering elements 14 after pass upward through the spray Element 15 is spilt, is relaundered and the dedusting that cools down, flue-gas temperature reduces, saturated flue gas water capacity reduces, and moisture is from flue gas Separate out, then flue gas is dehydrated again by first dewatering elements 11, then after the water fender 13 interception, wherein Partial fume discharged from the gas outlet 101 so that the overall dehydration efficiency of the dehydrator 100 reaches 98%.

To sum up, if due to the cylinder 10 from the position of first dewatering elements 11 to the top of the cylinder 10 be equipped with A dry tapering type structure 12, is equipped with water fender 13 between adjacent two tapering type structures 12, the water fender 13 oneself It is obliquely installed by end, it is possible to avoid the moisture by first dewatering elements 11 abjection from being expelled directly out, avoid diffusing There is " rainy " situation in chimney, so as to improve dehydration efficiency.

Embodiment described above only expresses certain embodiment of the utility model, its description is more specific and detailed, But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this area For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
