Description

(54) INSTALLATION FOR HEAT TREATMENT OF SILICATE BRICK

heatsatoprovotsa is made in the lower part of the airtight container 9.

A pipe 10 of the reverse heating and hot water supply system 10 is introduced into the tank 9. In the lower part of the tank, there is a pipe with spouting holes for bubbling, which is connected to the condensate line, in the upper part there is an air pipe 11 with a check valve 12 (the valve opens when there is excess pressure in the tank).

In the lower part of the tank, there is a suction nozzle 13, circulating ion pumps 14, which feed the ode through the supply line 15 into the rubnsí space of the heat exchanger.

The installation works as follows o & paaoMi

Through line 5, the exhaust steam enters the device 4 for cleaning and separating steam.

 the autoclave chamber is supplied through the condensate line 3. At the initial point in time, the autoclave system is a cleaning device — the steam consumer is under the working pressure of the autoclave. As the pressure drops in autoclave 1, the vapor saturation temperature decreases. This entails boiling of the liquid in the device 4, with the result that on the one hand vapor of re-boiling is formed, and on the side of the steam conductor the emulsion effectively precipitates mechanical impurities

Thus, steam and condensate are obtained.

From the device 4, the purified steam enters the annular space of the heat exchanger, where it is condensed, heating water in the pipes reaches 90-1U. Condensate enters into the tank 9.

When the heat exchanger cannot provide condensation of the entire steam, the steam pipe to the amulsi enters the tank, 9, where it is triggered by sparging.

The water from the tank 9 with a temperature of 60-8 ° C is supplied to the tube spaces to the heat exchanger, from where, with a temperature of 9 ° -11 ° C, to the nearest main line of the heating system and hot water supply (water supply 16,

Through the return pipe, the soda with a temperature of 6O-7OC enters the tank, mixes with the condensed steam and enters the suction inlet 13 of the circulation pumps 14,

On the return line installed valve 17, which regulate the system in such a way that the reverse ma-. the gistral is under pressure.

Pipe 18 leaves the cleaning device 4, and condensate is removed from the cleaning device to prepare a silicate mass.

The use of the proposed installation for the heat treatment of silicate bricks and other products in comparison with the existing installation provides the following advantages:

concentrated condensate is obtained for the preparation of silicate mass in the production of silicate bricks, which shortens the cycle of autoclave heat treatment of raw brick and provides savings from reducing the lime scale;

increases the service life of the heat exchanger and pipelines;

An additional amount of steam is obtained by steam rewash, which can be recycled.

form pa invention

A silicate brick heat treatment plant containing an autoclave and a heat exchanger boiler with a hermetic tank, so that, in order to increase the service life of the heat exchanger and to obtain a condensate concentrate saturated with the silicate, it is equipped with steam cleaning and separation equipment autoclave and boiler heat exchanger.
