They are suitable for chemical, industrial, engineering, metallurgy, environmental protection and other industries. 1.2.2 Demisters can be installed in the upper part of the submersible and can be used as independent gas-liquid separation equipment. According to legal requirements, one or two layers of demister elements can be installed in the demister, which is used for regular cleaning, inspection or replacement. 1.2.3 The suitable pressure of the demister is wide. Applicable short-term bacteria pressure: stainless steel ≤ 400 ℃; broken hook 300 ℃, 3.1.4 The material of the defoamer is: <1) The whole steel and defoamer and supporting components are all stainless steel; (2) The wire mesh is stainless steel. The frame and supporting components of the defoamer are pins: (3> The wire mesh is made of other non-metallic wires. The frame and supporting components are stainless steel or carbon copper. 1-2.5 The applicable gas flow rate of the defoamer (calculated by the effective transverse area of the gas passing through the defoamer) ranges from 2.5 to 4.5 m/5; the suitable gas velocity for the acid industry is s~4 m/a. The mist particle mass in the gas is >um, and the mist concentration is 100/m. For sulfuric acid industry, when the gas flow rate is: 3.2m/s, the particle size is >5%m, the defoaming rate is >98%. 1 GBJ237 GB 5117 JB 12-3: Stainless steel plate .

The components are combined and modified as shown in Figure 3.1. Then the mesh is drawn or placed in a cylinder with a guide rail and a sealing plate. 3.1.2 The mesh is replaced by a natural mesh group or a mesh connected to the net. It is divided into two types: 10 (mm and 15 mm. 3.1.3 Guide rail, sealing, drawer Made of steel inlay welding. 4 The defoamer element is allowed to be installed through the new port (i.e. the exhibition can be connected to the student or approved by the 3.1.5 comprehensive course. The element is generally set in 1-2 rooms. Figure 3.1.1 Service Components 3.2 Specifications The defoamer is a detachable structure.
