Description

one

The invention relates to the building materials industry, in particular to equipment for the production of staple fibers from glass or rocks.

A device is known for producing a 5-core fiber, which includes a mixer with a feed w, gas and air through them, a combustion chamber containing a housing with a cooling jacket, lined with refractory material from the inside, and a slit nozzle 1.

Cooling the body of the combustion chamber with water reduces its reliability, since in the event of a water supply cut-off, it quickly goes down. Together with the outgoing 15 heated water, irretrievable losses of teila occur, which reduces the efficiency of the device.

The purpose of the invention is to increase the reliability and efficiency of the device.

For this purpose, in the device for obtaining 20 staple fibers, including a gas and air supply lines, a combustion chamber, comprising a housing with a cooling jacket, lined with refractory material from the inside, and a slotted nozzle, the cooling jacket of the housing is made in the form of heat pipes where the evaporation zone is located at the point of their contact with the lining, and the condensation zone is installed in the air iodachi line into the mixer.

The drawing shows a device for staple fiber receiving, a slit.

A device for producing staple fiber includes a mixer 1 with gas supply 2 and air 3, a combustion chamber containing a metal body 4 with a cooling jacket lined with a refractory material 5 N on the inside and a dripping flange to which a water-cooled slit nozzle 6 is attached. Above the body 4 The combustion chamber has a distribution device 7 with channels 8 through which the prepared gas-air mixture enters the thinnest space 9 of the combustion chamber.

The cooling pipe of measles) 4 is made in the form of heat pipes, the inner surface of which is covered with a capillary-porous structure 10, such as a metal grid, filled with liquid heat transfer fluid, water. At the point of contact of the heat pipes with the refractory material 5, a psiareip 11 zone is located. The evaporation zone 11 is connected to one or several connecting channels 12, having a circular or other cross-section, with one or several finned zones of condensation 13 of the thermal element. The condensation zone 13 can also have a round, rectangular or other cross-section, silver, for example, in the form of a pack of plates or disks 14 and enclosed in a casing 15, which is connected to the air supply line 3 to the mixer 1.

The connecting channels 12, as well as the area of the supply of 11 heat pipes, can be externally covered with heat insulating material, iairimer with glass wool.

The device operates in the following manner.

Gas and air are supplied w, their pipelines m 3 and 4 are respectively iodine iodine by pressure into mixer 1, where they are mixed in the required ratio. The gas-air mixture prepared from the mixer 1 enters the switchgear 7, from where it comes into contact with the combustion space 9 of the combustion chamber, where it burns. The resulting high-temperature combustion products expire through the nozzle nozzle 6, creating a flat, high-speed flow of the e-carrier. Primary grades 16 with the help of growing rollers 17 are introduced through the gap between the wedge, spruce nozzle 6 and the port of the nlastimpamp 18 into the flow of the power carrier. Under the action of high temperature, the ihervich fibers 16 are softened and bent along the jet, and then they are further melted and inflated to form elementary supernatural ultratoxic fibers.

The body 4 of the combustion chamber pnoteisivio is cooled with the help of a heat-transfer fluid, which is located in it. Heat from the refractory material 5 is transferred through the wall of the housing to the heat transfer fluid and is expended on its heat resistance. Under the action of the pressure difference, the heat transfer fluid moves to the condensation zone (s)

13, where they condense. The heat released during the co-occurrence of steam is removed by air as a result of heat exchange through the ribbed wall of the condensation zone 13. The condensate but the capillary-porous structure 10 returns to the zone 11, and the process is repeated. The heated air enters the mixer 1. Thus, the combustible mixture is heated in the combustion chamber and the mixture is heated.

The device provides reliable and transparent cooling of the body of the combustion chamber without the use of running water, due to which its incidence and

scrubbed water flow. As a result, the use of air as the cooling medium of air, and on the receipt of high-temperature and high e-maintenance costs, the efficiency of the device is increased, and, consequently, the specific fuel consumption is reduced. The annual eco-ohmic effect from the introduction was invented at one plant but on the production of staple fiber on average will be about 4.0 thousand rubles.
