SU21344A1 - The cupola with heated blast air in the regenerators - Google Patents

Description

 The subject of the present invention is a cupola with regenerators for

heating the blast air; It differs from the well-known cupolas of the Sehurmanna system in that the gases are discharged to the regenerators at the top level, which, according to the inventor, should increase the utilization rate of heat in the cupboard.

In FIG. 1 shows a vertical section of a cupola with regenerators along the line AB in FIG. 3; FIG. 2 - its vertical with gas inputs and a chimney; FIG. 3- horizontal section of cupola with regenerators; FIG. 4 is a front view of the annular valve; FIG. 5-position of the annular valve in the tuyere over the cross section; FIG. b - the location of the gates in the air duct; FIG. 7-location of the metal nozzle in the regenerator.

, The device of the proposed regenerative cupola and work on it are as follows. The fan 1 (Fig. 2, 3) is installed at the level of the factory floor and through riveted iron air duct 2 supplies air to the cupola 16. On the failure path, the air meets the iron gates 3 and 4 (Fig. 6), of which

one should always be closed for

air flow and the other is open.

When the gate 3 is open and the gate 4 is closed, air is directed through the tube b (Fig. 3) through the window 7 enters the bottom

A part of the regenerator 8 is made of fireclay bricks, which is faced from the outside with metal sheets fixed to the rails or rail, and inside the regenerator is filled with a metal nozzle made of cast iron or steel bars of rectangular cross section.

The air is heated as it passes from below; through a hot metal nozzle and enters the gas pipeline 9 (Fig. 1), where, meeting the closed gate Yu, will pass into a vertical outlet 12, will lift the hinged valve 13 with its pressure (Fig-7), will flow unhindered into the tuyere from the cupola and. through the nozzle 14 (fig. 3) into the furnace of the cupola itself 16. Next, the air, passing through the charge and fuel column, will be transformed into flue gas, passing through g39 conductor 18 (fig. 1), symmetrical and similar in structure to the previous gas pipeline 9, then it goes down to another regenerator 19, passes through the metal nozzles, heats up the latter so much that, dropping into the lower part of the regenerator 19, it will become cold and enter through the window 20 into the gas pipe 21, pass through; open smoke gate 22 (Fig. 2 and 3 in the chimney 24 and through the chimney 26 to the outside.

After a certain period of time when the metal nozzles in re ;; 8. h generator, mean;} but cool

Make sure that all the gates of the eov b 2 2 || system are reattached to the system in such a way that the air from the fan is forced to be blown in the opposite direction. At the same time, it is not necessary to keep in mind only that during the lerekidke of the gates it is necessary to throw smoke gates 23 and 22 first; then the air from the fan 1 will go to the regenerator 8, and through the window 25 liters of smoke to the chimney. In this short period of time, the burning in the cupola should stop, and therefore, not for: to a large extent, her work is rejected {{gakidy}) gates 10 and 11 and then air gates 3 and 4.

The subject matter of the invention.
