Acid Fume Purification System

Basic Info

Model No.: SW Type

Product Description

1. Equipment Name

  SW Type Acid Fume Scrubber

2. Equipment Composition

The whole system is composed of suction hood, ventilation ducting, acid fume scrubber, blower, chimney, control valve, electrical cabinet, etc.

Set up suction hood overhead the pollution source, the suction hood will generate strong air attraction with force of the blower; the acid fume will be sucked into the ventilation ducting.

Function of the suction hood is to capture the acid fume and generate a strong negative pressure area, forcing the acid fume moving into the suction hood.

Function of the ventilation ducting is to ensure the ventilation of air flow.

Function of the acid fume scrubber: purifying the acid fume; the clean air will be sucked by the blower and be discharged through the chimney.

Function of the blower: the blower is just like the heart of the system, the power source of circulation air flow; the blower is placed behind the scrubber, which will protect the impeller from impact of high-speed and disordered dust particles, improving the service life and reducing the backpressure, ensuring the normal long-term operation.

Function of the circulation water pump: to spray alkaline liquid and neutralize acid fume, and make it recycled.

The acid fume will be integrated into the scrubber, and the treated air will be discharged from the chimney via the blower. Each suction hood is equipped with independent air valve for adjusting the air flow; if there is no need to open at the same time, the operator can close it, making the negative pressure of the running suction hood much stronger, more beneficial to the acid fume gathering.

 

3. Technical Features

3.1 Treatment Process

   There will be sulfuric acid fume during battery formation, the particle size is very small (0.1~10um) and have strong corrosion. If without treatment, it will pollute the workshop environment and be very harmful to the operator`s health. Therefore, we design the acid fume scrubber for the acid fume treatment.

3.2 Process

Acidic air suction hood ventilation ducting SW acid fume scrubber blower exhaust chimney meeting the emission standard and discharged into the air

3.3 Structure Features

3.3.1 The system adopts automatic PH dosing system, the operation will be more accurate and convenient.

3.3.2 It adopts turbulence performance of small packing balls, air-liquid contact surface area is big, with good mass transfer effect, low running resistance, no blocking.    

3.3.3 It adopts alkaline liquid as absorbent, with sufficient reaction and purification efficiency.

3.3.4 The blower is glass fiber reinforced plastics, with stable performance and long service life.

3.3.5 The blower is with low running noise.

3.3.6 The purification efficiency of the acid mist can reach up to 95%.  

3.4 Working Principle

With the dynamic strength of the blower, the acid fume will go through the suction ducting into the acid fume scrubber. The acid fume will go up the first level spraying section from the bottom of the scrubber. The absorption liquid will spray out from the evenly placed nozzles; the numerous fine fog-drops will contact with the air and have chemical reaction. The air will go up to the packing layer. The turbulence of the small packing balls, with the wind dynamic force, will make the air phase lead have chemical mass transfer reaction with the strong alkaline matter in the spray. The reacted substance will flow down to the bottom storage tank. The harmful air which hasn`t been completely absorbed will go up to the second level spraying section. The absorption liquid will spray out from the evenly placed nozzles; the numerous fine fog-drops will contact with the air and continue to have chemical reaction. Just like the first level absorption process, the air will enter into the demister on the top of the scrubber. The absorption liquid contained in the air will be cleared away and the clean air will be discharged into the atmosphere through the exhaust chimney. The absorption liquid can be recycled to be used. The sediment inside the water tank should be removed manually.

In order to reduce the noise, the following measures are taken:

* Inlet and outlet of the blower have flexible connection with the ducting, to reduce the vibration noise;

* There is soundproof room outside the blower t recue the noise; the exhaust fan is used for heat dissipation.

3.5 Acid Fume Collection Method

The circulating water inside the scrubber should be discharged at regular intervals, the discharged leaded sewage should be discharged to the sewage treatment station
