Description

(54) CYCLONE UNIT FOR MELTING SILICATE MATERIAL

one . -

The invention invented to the industry of construction materials, namely, to smelting aggregates for the study of melt in the minerapean production.

The disadvantages of this melting unit are the inability to melt granular charge, the temperature of the burning combustion products is high (), and the heat is not sufficiently used 15 due to the small size of the pool under KIEL, therefore these products of combustion must be diluted with cold air before entering the recovery unit (recuperator).

The purpose of the invention is to utilize the heat of combustion products and improve the quality of the melt.

The delivered chain is achieved by the fact that the cyclone aggregate for si-b. the latex material containing a charging device, a cyclone with burners, a smelting pool and a heat exchanger are equipped with a unit for melting grain material with a pool located between the cyclone and the recuperator, soob. It is installed at a distance of 1–2 minutes of the cyclone basin, and the depth of the cyclone basin is 23 depths of the melt installation of granular materials.

The drawing shows a cyclone unit, a longitudinal section.

Claims (2)

The cyclone unit for melting silicate material contains a cyclone 1, a melt plant 2 with granular materials 3, a cyclone pool 4, a baosein 5 melt plant, a charging shaft 6, a burner 3 & 7 feeders, cyclones 8 cyclones, grips 9 of melting grain materials, revupper 10, outlet 11, hopper 12 of grain materials, hopper 13 dispersed. The unit operates as follows. Melting materials, for example, fiber-forming waste, are loaded into the vault of the melting installation of granular materials 5 through the charging mixture, for example, before forming xyus from this material, which blocks gas outflow through the charge 6. The burner 7 of the feeder is turned on and the latter is heated to the operating temperature . Bitters 8 of the cyclone are turned on with simultaneous disperse charge feeding into the upper part of the cyclone 1. The resulting melt flows down its walls into the basin: 4. The burners 9 of the melting unit installation of granular materials are turned on, the combustion products from which are mixed with the combustion products from the cylinder 1 and providing. The melting of the waste cone, which replenishes as the material settles in the charge 6, melts. The melt formed during the melting accumulates in the basin 5 of the plant for the melting of granular materials 5, and then flows into the basin 4 cyclones, g e mixed with the molten charge and dispersed further preheated. The oxidative heating and homogenization of the melt is ensured in the feeder 3. The movement of the melt in the aggregate towards the flow of combustion products ensures good overheating and homogenization of it, which contributes to the improvement of the quality of the blown. The location of the installation 2 for melting granular materials on the path of high-temperature gases of the cyclone 1 at a selected distance between the installations allows the use of the heat of the combustion products of the latter. In addition, incompletely molten, larger grains of waste enter the cyclone pool, which is 2-3 times deeper than the depth of the melting pool of 5 grains of materials, which ensures the final melting of these grains, reliable mixing of the melt by the stream of combustion products, and exiting the cyclone . The heat of the products of the hyphenic cyclone melting unit is used in the river. peratore 10,. The application of the proposed cyclic unit allows to provide waste-free production of the smelting department of the mineral wool production line, reduces the need for charge materials, reduces heat consumption and increases the quality of the melt. Claim 1. Cyclone aggregate for melting silicate material containing a cyclone loading device with burners, a smelting pool, a recuperator, from which, in order to recover the heat of combustion products and improve the quality of the melt, it is equipped with a plant located between the cyclone and the recuperator for melting granular material with a pool communicating with the cyclone pool and the feeder during the melt production. 2. The unit according to claim 1, wherein the plant for melting granular. Tarn; set at a distance of 1-2 longitudinal sizes of the cyclone basin, and the depth of the cyclone basin is 2-3 depths of the melt plant of the granular material.
