Abstract

The utility model discloses a three-level tail gas purifying tower system device for high-concentration nitrogen oxides. The three-level tail gas purifying tower system device for the high-concentration nitrogen oxides comprises a fan, a purifying tower and air guiding pipes, wherein the purifying tower comprises three purifying towers, the three purifying towers are in different levels and are connected with the fan through the air guiding pipes in sequence, and each air guiding pipe connects an air outlet in the top portion of the purifying tower which is in an upper level with an air inlet in the bottom portion of the purifying tower which is in a lower level. Compared with the prior art, the three-level tail gas purifying tower system device for the high-concentration nitrogen oxides has the advantages that the problems that in the prior art, negative pressure is not stable in operation process of production equipment, waste gas can not be disposed completely, and yellow smoke is generated are solved; and the three-level tail gas purifying tower system device for the high-concentration nitrogen oxides is small in occupied space and centralized in treatment, investment is reduced, and management cost is greatly lowered.

Description

Three grades of tail gas purification tower system and devices of high concentration nitrogen oxide
Technical field
The utility model relates to emission-control equipment, especially relates to three grades of tail gas purification tower system and devices of a kind of high concentration nitrogen oxide.
Background technology
In professional production manufacture of solar cells fabrication process technique, can produce some water-soluble gas waste gas, for example: (HNO3, HF, HCL, KOH).From its physico-chemical property, such as direct discharging, can certainly will pollute atmosphere and surrounding environment.In front cleaning and rear cleaning link in the cell piece production, originally adopt sour gas sour gas and that do not conform to nitrogen oxide of the nitrogen-containing oxide of front cleaning and rear cleaning to carry out mixed processing; The treatment effect unstability can produce the tobacco (being oxides of nitrogen gas) that can't process in a large number simultaneously; Process not thorough.
The utility model content
The utility model is in order to solve above-mentioned deficiency, to provide a kind of high concentration nitrogen oxide three grades of tail gas purification tower system and devices.
Above-mentioned purpose of the present utility model realizes by following technical scheme: three grades of tail gas purification tower system and devices of a kind of high concentration nitrogen oxide, comprise blower fan, purifying column and wireway, described purifying column comprises three grades of purifying columns, and three grades of purifying columns are successively by wireway and blower fan
Connect, wireway is connected to next stage purifying column bottom air inlet by upper level purifying column top vent.
Described purifying column comprises tower body, water tank and spray system, and described spray system spraying layer is at least one deck, and described spray system comprises water pump, pipeline and spray thrower, and spray thrower is provided with nozzle, and tower body is provided with form.
Operation principle of the present utility model: this equipment is under the effect of system's main air blower, gas enters upwards motion in the tower by elementary tail gas purification tower lower inlet, the drop of nozzle ejection moves downward, in the tower inserts is housed simultaneously, the contact area of increase and gas makes gas fully contact with drop, reach clean-up effect, clean gas is discharged through the demist layer on upper strata because some gas componants are different, in addition with acid solution or alkali lye as washing absorption; The gas of crossing through primary purifying enters upwards motion in the tower by intermediate tail gas purification tower lower inlet, after the process in the elementary tail gas purification tower of circulating, gas enters upwards motion in the tower, the process in the elementary tail gas purification tower that circulates equally by third level tail gas purification tower lower inlet again.Thoroughly reach discharging standards through tertiary treatment waste gas later, there is no the tobacco phenomenon.
The utility model advantage compared with prior art is: this three grades of tail gas purification tower system and devices of innovation type high concentration nitrogen oxide, solved the unstability of background technology in production equipment negative pressure in service, and exhaust-gas treatment does not thoroughly reach the tobacco phenomenon.Occupation area of equipment is little, processes centralization; The management of investment cost reduces greatly.

Fig. 3 is the structural representation of the utility model spray system.
Fig. 4 is the internal structure schematic diagram of the utility model purifying column.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, three grades of tail gas purification tower system and devices of a kind of high concentration nitrogen oxide, comprise blower fan 1, purifying column 2 and wireway 3, described purifying column 2 comprises three grades of purifying columns, three grades of purifying columns are connected with blower fan 1 by wireway 3 successively, and wireway 3 is connected to next stage purifying column bottom air inlet by upper level purifying column top vent.
As shown in Figures 1 to 3, described purifying column 2 comprises tower body 21, water tank 22 and spray system 23, and described spray system 23 spraying layers are at least one deck, and described spray system 23 comprises water pump 231, pipeline 232 and spray thrower 233, spray thrower 233 is provided with atomizer, and tower body 21 is provided with form 4.
As shown in Figures 1 to 4, operation principle of the present utility model: this equipment is under the effect of system's main air blower 1, gas enters upwards motion in the tower by elementary tail gas purification tower lower inlet, and the drop of nozzle ejection moves downward, and in the tower inserts 5 is housed simultaneously, increase the contact area with gas, gas is fully contacted with drop, reach clean-up effect, clean gas is discharged through the demist layer 6 on upper strata, because some gas componants are different, in addition with acid solution or alkali lye as washing absorption; The gas of crossing through primary purifying is by intermediate tail gas purification tower bottom
Import enters upwards motion in the tower, and after the process in the elementary tail gas purification tower that circulates, gas enters upwards motion in the tower, the process in the elementary tail gas purification tower that circulates equally by third level tail gas purification tower lower inlet again.Thoroughly reach discharging standards through tertiary treatment waste gas later, there is no the tobacco phenomenon.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
