Description
Technical Field
The utility model belongs to the technical field of tail gas treatment, concretely relates to spray column for administering VOC waste gas.
Background
The statements herein merely provide background related to the present disclosure and may not necessarily constitute prior art.
VOC exhaust gas is an exhaust gas containing volatile organic compounds, such as exhaust gas discharged from automobiles, exhaust gas generated in chemical production, and the like. The liquid absorption method is a common technology for treating VOC gas, and adopts liquid absorbents such as water or alkali liquor and the like to circularly spray and absorb VOC waste gas in a spray absorption tower.
The inventor finds that the absorbing liquid is difficult to be uniformly sprayed by the existing spray header, so that the purifying effect of the VOC gas is poor. In addition, since the VOC exhaust gas generally contains a large amount of solid particles, when the absorption liquid is repeatedly sprayed, the solid particles concentrated in the absorption liquid easily cause clogging of the spray header.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a spray column for administering VOC waste gas to the not enough of prior art existence.
In order to achieve the above purpose, the present invention is realized by the following technical solution:
a spray tower for treating VOC waste gas comprises a tower body, wherein the tower body is sequentially provided with an absorption liquid storage tank, an air inlet, a spray layer and an air outlet from bottom to top, and a plurality of spiral spray heads are arranged on the spray layer;
the spiral nozzle comprises a mounting seat body and a spiral flow channel, and is mounted on the bracket of the spraying layer through the mounting seat body;
the mounting seat body is arranged in a hollow mode, the spiral flow channel is formed by a spiral groove body, the spiral groove body is of a spiral structure with gradually changed spiral radius, and one end, with a large spiral radius, of the spiral groove body is mounted on the mounting seat body;
the cavity of the mounting seat body is communicated with the absorption liquid storage tank through a circulating pump and a pipeline;
through holes are uniformly distributed on the spiral groove body.
Above-mentioned the utility model has the advantages as follows:
the shower nozzle is spiral shower nozzle, and it includes the spiral runner that is enclosed by the spiral groove body, and the equipartition through-hole on the spiral groove body, and the absorption liquid tangential of pump income flows into spiral runner, along the in-process that spiral runner flows down, can spray to spiral shower nozzle all around through the through-hole of equipartition, can effectively enlarge the scope of spraying of absorption liquid.
In addition, the spiral runner is the structure of spiral radius gradual change, and the big one end of spiral radius is installed on the installation pedestal, and absorption liquid is along the spiral runner flow in-process, owing to constantly have absorption liquid to spray to the shower nozzle all around through the through-hole, so the volume of the absorption liquid that flows along the spiral runner reduces gradually, and the velocity of flow reduces, so dwindles the spiral radius gradually, helps absorption liquid to flow along the spiral runner all the time, sprays to all around. And, because the spiral radius reduces gradually, the radius of spraying of absorption liquid reduces relatively, can further improve the coverage area of absorption liquid, more is favorable to realizing the even absorption that sprays of VOC waste gas.
The spiral flow channel is formed by a spiral groove body, and the spiral groove body is of an open structure, so that the blockage of the spiral flow channel can be effectively avoided, and the continuous and stable operation of the system is facilitated.
