Carding process design eight steps of the design of the technology

[introduction] do people have a bitter tears, the design work throughout the whole period of the whole project. Tedious work and communication links, so it is clear what the time to do what is very important.
First, the design preparation
1, familiar with the design tasks and design content, a comprehensive understanding of the design requirements of the topic.
2, to understand the topics related to the content, collect information, discharge design schedule.
3, access to documents and process routes, process and key equipment of the data, and to collect information on the scope of application of screening.
4, collect the relevant design information, in-depth production site investigation, digestion, screening, absorption and classification.
Two, determine the production method
1, collect information, investigation and research
2, the implementation of key equipment
3, a variety of production methods of the technical, economic, security, comparative analysis
4, the selected production process modification, supplement, perfect
5, waste management, eliminate pollution
Three, process design
1, determine the composition of the entire production process, to determine the composition of each process or process
2, determine the control scheme, determine the connection method of each process, select the appropriate instrument
3, the establishment of the process plan (conceptual design block diagram), outlining the process of material flow sketches, and constantly revise, supplement, improve
Four, chemical calculation and drawing of the main equipment, piping and instrument flow construction plans
1, according to the basic data of the material balance, heat balance and equipment selection process calculation, determine the production equipment type, size and number, material preparation, equipment list
2, draw the main equipment drawing, drawing the construction stage pipeline flow chart
Five, workshop layout design
1, task: determine the boundary area of the plant and site configuration, plant or frame structure, to determine the process flow chart of all equipment in the plane layout of the specific location
2, drawing: drawing plane and elevation workshop layout
Six, chemical pipeline design
1, tasks: according to the transport media physical and chemical parameters, select the flow rate, calculate the diameter and pipe material, wall thickness, determine the pipe connection and pipe rack form, height, span, etc.. Determine the process flow diagram of all pipelines, valves, pipe rack, pipe fittings, to meet the process requirements, ease of installation, maintenance, neat and beautiful
2, drawing: drawing plane and elevation workshop piping layout
Seven, to provide design conditions
To other general layout, construction, pipe, equipment, water, electricity, gas, refrigeration and other non professional design process conditions, make better service for other professional production facilities.
Eight, the preparation of design specifications
1, design specification, design personnel in the completion of the workshop (device) design, designers need to index and description of the problem in order to clarify the design of the advanced technology, process, equipment and operation control method, and the preparation of the
The final product 2, workshop design is the design specifications, drawings (general layout diagram, flow chart, equipment layout, equipment etc.) and schedule (equipment list, material summary etc.)
