Boiler water high-utilization-rate method

Abstract

The invention relates to a boiler water high-utilization-rate method, which comprises the following steps of: putting a collection basin into the bottom of a high-temperature furnace, adding 3 per thousand to 8 per thousand of anhydrous trisodium phosphate into a high-temperature furnace, heating the high-temperature furnace to 400-500DEG C for processing, taking out the collection basin, cooling and icing collected precipitates, and putting the collection basin back to the bottom of the high-temperature furnace; adding a new material into the high-temperature furnace in proportion, raising the temperature to melt the cooled mixed precipitate, and then reducing the temperature and testing the furnace to produce glass; and raising the temperature in the high-temperature furnace to 450DEG C for processing for 24h. The method further involves a precipitation basket, the collection basin is pushed into the precipitation basket, and then the precipitation basket is placed at the bottom of the high-temperature furnace; the collection basin and the precipitation basket are made of nickel-based alloy; according to the boiler water high-utilization-rate method, a large amount of time and cost are saved, and the production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of furnace water recycling in the glass hardening process, in particular to a method for high utilization of furnace water. Background technique [0002] Corning GG5 glass is a lithium component glass, and the cost of hardening is very high. The life of the furnace water is limited, and the furnace water needs to be changed frequently. Although adding TSP (trisodium phosphate anhydrous) can solve the problem, TSP will interact with the glass in the sodium potassium furnace water. Lithium ion components are replaced in the middle of the product, and the lithium ion components will become precipitated solidified residues, and the residues will accumulate at the bottom of the cylinder, covering the area of ​​the heating tube, and sticking to the glass during the product pushing action, causing the glass to turn blue, foggy, and white Points and so on are bad, and adding TSP at most 2 times will completely cover the hea...

[0002] Corning GG5 glass is a lithium component glass, and the cost of hardening is very high. The life of the furnace water is limited, and the furnace water needs to be changed frequently. Although adding TSP (trisodium phosphate anhydrous) can solve the problem, TSP will interact with the glass in the sodium potassium furnace water. Lithium ion components are replaced in the middle of the product, and the lithium ion components will become precipitated solidified residues, and the residues will accumulate at the bottom of the tank, covering the area of ​​the heating tube, and sticking to the glass during the product pushing action, causing the glass to turn blue, foggy, and white Points and so on are bad, and adding TSP at most 2 times will completely cover the heating pipe area, resulting in abnormal furnace temperature control and affecting product strengthening parameters, resulting in the inability to continue production. It is necessary to clean the tank, beat the furnace water and replace the whole raw material before normal production can be carried out; each time Replacing hardened raw materials requires boiler water, bottoming, tank washing, maintenance, feeding, heating, and re-commissioning; the labor time is long, the efficiency is low, and it takes a lot of manpower and time to replace each time, so the capacity of a single machine is small and the utilization rate of equipment is low. , seriously affecting production efficiency
