Description

A kind of spray tower for waste gas

Technical field

Technical field of waste gas treatment is the utility model is related to, more particularly, to a kind of spray tower for waste gas.

Background technology

Existing spray column, including tower top, tower main body and bottom of towe, are provided with demisting between tower top bottom and tower body top Device, demister lower section are provided with spray Rotating fields and filler Rotating fields.The spray column of this structure due to demisting layer diameter with Packing layer is identical, and gas flow rate is also identical, if gas flow rate is too high in spray column, defogging effect is bad.For enhancing demisting effect Fruit, it would generally now increase the diameter of overall tower main body, raising production cost that so can be larger.

In addition, the U of Authorization Notice No. CN 203577539, authorized announcement date 2014.05.07 Chinese patent disclose A kind of scrubbing tower, including tower body, tower top, demisting layer and scrubber layer, the demisting layer and the scrubber layer are located at the tower The inside of body, and the demisting layer is located above the scrubber layer, the top of the tower top is fixed with to be connected with the tower top Waste gas outlet, the side wall of the tower top is provided with the first form, and the side of first form, which is provided with, is fixed on the tower top On put and stay frame, described put stays frame to be fixedly connected with the upper end of cat ladder, and the lower end of the cat ladder is fixed on ground.The scrubbing tower The condensation that coil pipe is used for water mist of gas is provided with inside middle demisting layer, ensures to exclude the drying of gas, but energy consumption is higher, and adopt It is unsatisfactory with single type demisting layer, defogging effect.

Utility model content

The utility model is to solve the problems, such as the spray column of prior art, there is provided a kind of compact-sized, demisting effect Rate is high, the good spray tower for waste gas of defogging effect.

To achieve these goals, the utility model uses following technical scheme：

A kind of spray tower for waste gas, including tower body, water tank, water inlet manifold and water pump, the tower body top are provided with gas outlet, institute State tower body two bottom sides and be respectively equipped with exhaust gas entrance and water smoke recovery port, the water smoke recovery port is connected by pipeline with water tank It is logical, be provided with packing layer and the compound demister above packing layer in the tower body, under described filler layer and compound demister Side is respectively equipped with the shower being connected with the water inlet manifold outside tower body, and the shower bottom is located at spray head, described Compound demister includes the fine defogging block that overlaps up and down and liquid mist entrapment plate is formed, the liquid mist entrapment plate by polylith side by side and Spaced Multifolding Corrugated Plate is formed, and the gap between the Multifolding Corrugated Plate forms and catches mist passage, and the mist of catching leads to The inwall in road is provided with collision fin.To solve the problems, such as that existing spray column defogging effect is bad in the utility model, specially use A kind of improved compound demister of structure, the air-flow that many sub-threads are separated into after gas ascends into liquid mist entrapment plate enter Mist passage is caught, in the presence of inertia force, the collision of drop mist forms liquid film, liquid film on Multifolding Corrugated Plate and collision fin Under gravity be separated after moving forward to Multifolding Corrugated Plate and the turning point for colliding fin with air-flow, and not by The fine drop mist of removing enters in fine defogging block, is hit with the silk screen in fine defogging block and attached to it, and then Gradually collect at the intertwined point of each silk thread, due to the effect of the capillarity of slot and the surface tension of liquid at intertwined point, Drop is rested at the intertwined point, change is gradually condensed greatly by repeatedly adsorbing drop repeatedly, until the drop gravity of aggregation exceedes During the combined force that surface tension and gas rise, drop down drops, so as to reach the purpose for removing fine drop mist； Catch the uniformity that mist passage is advantageous to control gas flow rate；Compound demister space availability ratio in the utility model is imitated with demisting Rate is high, and defogging effect is good.

Preferably, the spacing between the Multifolding Corrugated Plate is 20 ~ 50mm.Spacing control between Multifolding Corrugated Plate System is smaller in 20 ~ 50mm, pressure drop.

Preferably, the collision fin overall structure is in " Z " font.It is in " Z " font to collide fin overall structure, favorably In reducing gas flow rate, avoid gas flow rate too fast.

Preferably, the fine defogging block is interwoven by fiber wire.

Preferably, the compound demister is fixed in tower body by upper press ring, lower pressure ring, the upper press ring is crimped on Fine defogging block top surface, described push are located on liquid mist entrapment plate bottom surface, and the upper press ring edge, lower pressure ring edge difference are outside Extension forms connection flange, and the connection flange is fixedly connected by bolt with tower body inwall.Upper press ring, lower pressure ring are fixed compound Demister, Stability Analysis of Structures, and convenient disassembly.

Therefore, the utility model has the advantages that：Compact-sized, pressure drop is small, and demisting efficiency is high, defogging effect It is good.
