1, field investigation
After accepting the design task, it is necessary to conduct on-the-spot investigation on the source of exhaust gas. The focus is on the investigation of pollution sources to understand the types, displacement and emission methods of waste gas. In addition, it is necessary to have a certain understanding of production scale, production layout, production technology, raw material source and waste gas recovery.
Step 2 determine the plan
According to the investigation, the technical scheme of waste gas treatment is demonstrated, and the waste gas treatment method, equipment type and waste gas treatment process are determined.
3. Design and calculation
Firstly, the design parameters are determined according to the design requirements or previous experience data. Determine the overall dimensions of the equipment through material balance. The internal structure of equipment is determined by the principles of heat balance, fluid mechanics and material mechanics.
Step 4: Draw.
Draw the general assembly drawing and parts processing drawing of waste gas treatment equipment. Technical requirements that cannot be fully expressed by views should be expressed in words under "Technical Title".
2. What are the basic requirements for waste gas treatment equipment?
A set of good waste gas treatment equipment shall meet the following basic requirements:
1, the gas and liquid in the equipment should have enough contact area and contact time.
2. The gas-liquid disturbance is strong, which reduces the mass transfer resistance and improves the absorption efficiency.
3. The waste gas treatment has a wide working range and stable operation.
4. The waste gas treatment equipment has small resistance and low energy consumption.
5. It has enough mechanical strength and corrosion resistance.
6, simple structure, easy to manufacture and maintain.
Most industrial waste gases are flammable, explosive, toxic and harmful organic substances and compounds. This dangerous chemical substance is very important for the safety of waste gas treatment equipment in waste gas treatment engineering. Our design and manufacturing principles are: safety is very important, followed by environmental protection emission standards. All the work is meaningless if the equipment is unsafe.
