How to deal with waste gas from paper mill?

 How to deal with the waste gas from paper mills? Botou jinzhu environmental protection equipment co., LTD is specialized in producing waste gas treatment equipment for paper mills. Paper mill waste gas is produced in pulping process gas, such as line from pulp, steam pot, causticizing and stripper NCG condensate gas, its composition containing H2S, CH3SH and CH3SCH3, CH3SSCH3 sulfur-containing compounds, still contain turpentine oil, methanol steam, water, steam, nitrogen, oxygen and other gases, corrosive, poisonous and explosive. The waste gas produced by pulp bleaching and chemical preparation is chemically treated by the waste gas scrubber, converted into pollution-free air gas, and then discharged into the atmosphere.

1. Water spray: make use of the odor, some of the organic waste gas soluble in water characteristics, so that the odor, organic waste gas components in direct contact with water, so as to dissolve in water to achieve the purpose of removal. It is suitable for water - soluble, odorous and organic waste gas. Process is simple, convenient management, equipment operation cost is low, spray tower purification equipment imported PP plate as the main materials to design and manufacture, the internal spray layer USES the PP polypropylene material raschig ring packing, according to the gas absorption process in gas liquid two phase interface, transmission rate and interface area is proportional to the principle of packing is used to increase the contact area of two phase, make two phase dispersed adequately, achieve the goal of waste gas treatment.

Structural characteristics of

Spray tower purification equipment based on factors such as customer space management can design of vertical and horizontal two kinds, paper mill waste gas treatment equipment manufacturer to the working principle of vertical structure for gas liquid two phase inverse contact, the working principle of horizontal structure for gas and liquid two intersecting tributary contact, waste gas by liquid phase contact absorption and packing layer, so as to achieve waste gas purification effect. The packing layer in a single tower can be divided into single or multiple layers.

   advantages

The removal efficiency of the equipment is up to 97%, good performance, strong corrosion resistance, light weight, easy installation and maintenance, high strength, beautiful appearance, small footprint, low operation and maintenance cost, etc.

Applicable scope of spray tower purification equipment

It is suitable for the absorption, washing or purification of waste gas produced by chemical industry, petroleum, semiconductor, medicine, food, printing plant, metallurgy, laboratory, electroplating and other industries.

A. pressure loss: <390-780pa.

B. Applicable temperature: PP material is -10℃-120℃.

C. Specifications of vertical tower, treatment capacity: 300-5000mm, exhaust gas treatment capacity: 1000m³/h -- 100,000m³/h.
