Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste gas scrubbing technology, and in particular relates to a waste gas scrubbing device with multiple nozzles for uniform spraying. Background Technology
[0002] Waste gas scrubbing, usually referring to waste gas scrubbing towers or wet scrubbing, is a method for treating industrial waste gas. Its basic principle is to reduce pollution emissions by absorbing, dissolving, or neutralizing harmful substances in the waste gas using a liquid (usually water or chemical reagents). Main characteristics and types: Wet scrubbing: uses water or solutions to wash waste gas, suitable for removing acidic gases or soluble particulate matter; Chemical scrubbing: adds chemical reagents to cause harmful substances in the waste gas to react chemically, such as absorbing acidic gases to form salts.
[0003] Most existing waste gas scrubbing devices use spraying, which has some shortcomings in practical applications. For example, the spraying system of some devices is not designed reasonably, resulting in uneven spraying, which prevents harmful substances in the waste gas from being fully absorbed, dissolved or neutralized, thus reducing the effect of waste gas scrubbing. Moreover, the spraying method is monotonous, and the waste gas treatment effect is limited.
[0004] In response, this application proposes a waste gas scrubbing device with multiple nozzles for uniform spraying. Utility Model Content
[0005] The purpose of this invention is to provide a waste gas scrubbing device with multiple nozzles for uniform spraying, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas scrubbing device with multiple nozzles for uniform spraying, comprising a tower body, an air inlet pipe connected to one side of the bottom of the tower body, a second liquid inlet pipe passing through one side of the top of the tower body, an annular pipe inside the tower body, the second liquid inlet pipe being connected to the annular pipe, a plurality of vertical pipes spaced apart at the bottom of the annular pipe, each vertical pipe having an atomizing nozzle on its side wall, a drain pipe on the bottom surface of the tower body, and an air outlet pipe on the top surface of the tower body.
[0007] Preferably, a partition is provided inside the tower body between the lower part of the vertical pipe and the upper part of the air inlet pipe. A connecting pipe passes through the top surface of the partition. A first liquid inlet pipe is connected to the side wall of the tower body below the partition. The partition divides the interior of the tower body into a spray zone and an immersion zone from top to bottom.
[0008] Preferably, each of the vertical pipes has a number of atomizing nozzles connected at intervals on its sidewall, with the liquid outlet end of the atomizing nozzle facing the central axis of the tower body.
[0009] Preferably, the vertical tubes are distributed in an equidistant circular pattern.
[0010] Preferably, a delivery pump is connected between the second inlet pipe and the annular pipe.
[0011] Preferably, the sidewall of the annular pipe is welded to the inner wall of the tower body.
[0012] This utility model has at least the following beneficial effects:
[0013] (1) This utility model sets up an annular pipe inside the tower body, and sets up several vertical pipes with atomizing nozzles at intervals at the bottom of the annular pipe, with the liquid outlet end of the atomizing nozzle facing the central axis of the tower body. The several vertical pipes are distributed in an equidistant circle. This design enables the spray liquid to be sprayed out evenly from multiple directions, forming a comprehensive and uniform spray coverage area, effectively solving the problem of uneven spraying in existing devices, allowing harmful substances in the exhaust gas to be fully absorbed, dissolved or neutralized, and greatly improving the effect of exhaust gas washing.
[0014] (2) This utility model divides the interior of the tower body into a spray zone and a immersion zone from top to bottom by a partition. The spray and immersion work together to greatly improve the effect of waste gas washing. Attached Figure Description

An air inlet pipe 6 is connected to one side of the bottom of the tower body 1, and a second liquid inlet pipe 9 is provided through one side of the top of the tower body 1. Specifically, the second liquid inlet pipe 9 is connected to a water tower or other chemical reagent tank. An annular pipe 10 is provided inside the tower body 1, and the second liquid inlet pipe 9 is connected to the annular pipe 10. Specifically, the second liquid inlet pipe 9, the annular pipe 10, and the tower body 1 are all fixedly connected. Several vertical pipes 11 are provided at intervals at the bottom of the annular pipe 10. Specifically, the vertical pipes 11 are fixedly connected to the annular pipe 10 and are interconnected. Each vertical pipe 11 has an atomizing nozzle 12 on its side wall. Specifically, the atomizing nozzle 12 is fixedly connected to the vertical pipe 11 and is interconnected. A drain pipe 8 is provided on the bottom surface of the tower body 1, and an air outlet pipe 13 is provided on the top surface of the tower body 1.
[0022] In this embodiment, exhaust gas is introduced to the bottom of the tower body 1 through the air inlet pipe 6. The exhaust gas moves upward and is introduced into water or other chemical reagents through the second liquid inlet pipe 9. The water or other chemical reagents enter the annular pipe 10 and are distributed in the vertical pipe 11 under the pressure of the delivery pump. The exhaust gas is sprayed through the atomizing nozzle 12. The treated exhaust gas is discharged upward through the air outlet pipe 13, and the treated water or chemical reagents are discharged through the liquid outlet pipe 8.

[0024] In this embodiment, water or chemical reagents are injected into the immersion zone 3 through the first liquid inlet pipe 7 to perform immersion treatment on the waste gas. This works in conjunction with spraying to greatly improve the waste gas treatment effect.
[0025] Furthermore, each vertical pipe 11 has several atomizing nozzles 12 connected at intervals on its sidewall, with the liquid outlet end of the atomizing nozzle 12 facing the central axis of the tower body 1.

[0027] Furthermore, several vertical tubes 11 are distributed in an equidistant circular pattern.
[0028] In this embodiment, the equidistant circumferential distribution further improves the uniformity of spraying.
