                 Titanium Dioxide Air Supply System Purchase Requirements and Description

                First. Purchase requirements
                 
                1, the scope of procurement:
                1) 2 Titanium Dioxide air delivery and cooling lines;
                2) For the equipment included in the production line, see "Schematic Diagram of Titanium Dioxide Blowing and Cooling System". Specific equipment includes, but is not limited to, a low-temperature bag filter, 2 fans, 3 bins (with oscillator), 4 star-type valve (lock valve), 5 tubes, 6 tubes and so on.
                3) The instrumentation, electrical components, etc. required for the production line.
                4) Equipment packaging, transportation, unloading, installation, commissioning and after-sales service.
                5) Relevant technical data, instructions for use, etc.
                2, the production line requirements:
                1) Physical properties of titanium dioxide: relative density 4.1-4.3g/cm3; sieve residue (45um, -325 mesh) ≤0.05% (mass fraction); water suspension pH 6.0-8.0; oil absorption ≤ 23g/100g Water extract resistivity ≥ 80Ωm; Repose angle ~ 600; Product final moisture content ≤ 0.4% (mass fraction); Final temperature ≤ 50 °C.
                2) The use of negative pressure gas phase transport requires titanium dioxide transport capacity of 6t/h. The exhaust gas is free of titanium dioxide products.
                3) The starting temperature of titanium dioxide product is ~130°C, and the cooling medium is atmospheric. The final temperature of the product is ≤50°C. The final moisture content of the product is ≤0.4% (mass fraction, how to avoid the influence of moist air?).
                4) The low-temperature bag filter (total filter area, equipment size, single filter bag size, etc.) requires reasonable structure design, smooth material feeding, and no internal material accumulation; 304 material is used for internal mirror polishing. Please provide equipment drawings or schematics, focusing on how to solve the problem of blanking and material accumulation.
                5) Silo (size Φ3200×3500, V≈30m3, internal vibration bucket or pulse air bag) requires reasonable structure design, smooth material discharge, and no internal material accumulation; 304 material is used for internal mirror polishing. Please provide equipment drawings or schematics, focusing on how to solve the problem of blanking and material accumulation.
                6) The fan selection (power, air flow, air pressure, etc.) is required to meet the production requirements and meet the energy saving requirements. Please provide equipment drawings or schematics.
                7) Selection of pipelines, fittings and valves. Material is 304. Diameter DN300 or DN350 or DN400 is optional (please specify).
                3. Equipment layout: Please arrange the equipment according to the characteristics of its own equipment. Please put forward the building requirements (plane size, height, load, etc.) for the workshop (steel structure).
                 
                Second, equipment list and quotation form
                 
                1. Describe the scope of supply, detailed technical parameters, working principles, and specifications of the production line and equipment.
                2. List of equipment, detailing equipment name, specification, model, installation size, material, weight, quantity, unit and supplier, main accessories and accessories suppliers of each equipment, etc. Please see the EXCEL attachment for the equipment list form.
                3. The list of quotations shall be in one-to-one correspondence with the equipment list, detailing the names, quantities and prices of individual equipment, accessories or service items, and indicating whether the quotation includes tax. Please refer to the EXCEL attachment for the list of quotation forms.
                 
                Third, other
                 
                1. It requires the production line equipment to have an effective operating rate of >90% in the first year.
