Then, burning burners in the fire-resistant test furnace (3) through a program to enable simulated flame to be provided in the fire-resistant test furnace (3), observing the change of the pressure in the fire-resistant test furnace (3) in the test process, adjusting a smoke pipe valve door (14) in the furnace to enable the pressure in the fire-resistant test furnace (3) to be kept in the range of national standard, continuously adjusting the opening of a smoke pipe valve (12) outside the furnace according to the size of smoke generated outside the furnace, enabling a smoke collecting cover (7) to collect the generated smoke through negative pressure difference, and enabling the smoke outside the furnace collected by the smoke collecting cover (7) to sequentially pass through a smoke collecting cover smoke pipe (9), a telescopic smoke pipe (10), a smoke pipe (11) outside the furnace, a smoke pipe valve (12) outside the furnace, a tee joint (15), a smoke cooling device (17), a smoke purifying device (18) and a harmful gas purifying device (19) to cool and purify the smoke, and then discharging the purified smoke which meets the national emission standard through a chimney (21);
The flue gas generated in the fire-resistant test furnace (3) enters a flue gas pipe (13) in the furnace through a flue in the fire-resistant test furnace (3), and sequentially passes through a flue gas pipe valve (14), a tee joint (15), a total flue gas pipe (16), a flue gas cooling device (17), a flue gas purifying device (18) and a harmful gas purifying device (19), so that the flue gas is cooled and purified, and then the purified flue gas meeting the national emission standard is discharged through a chimney (21);
The flue gas cooling device (17) cools the collected high-temperature gas, so that the temperature of the flue gas meets the temperature resistance requirements of equipment, pipelines and materials in a purification system, the cooling of the high-temperature flue gas is beneficial to the absorption and adsorption treatment of the gas, and the working efficiency of the flue gas purification device (18) and the harmful gas purification device (19) is improved to a greater extent; the temperature of the high-temperature flue gas is reduced, so that the volume of the flue gas is obviously reduced, the specification of the purifying equipment can be reduced, and the energy is saved;
In the fire resistance test process, large-particle smoke dust or harmful gas can be generated in or outside the furnace due to the combustion of the combustion detection sample (1), and the smoke dust purifying device (18) filters and adsorbs large-particle matters in the smoke dust to prevent the emission of the large-particle matters;
The harmful gas purifying device (19) filters harmful gas in the smoke dust, ensures that the concentration of the harmful gas meets the relevant regulations of national requirements, ensures that the emission of the smoke dust reaches the national emission standard, and reduces pollution to the greatest extent; the induced draft fan (20) provides gravitation for the whole set of system, provides gravitation for collection petticoat pipe (7) and fire-resistant test stove (3), guarantees that the pressure in the stove accords with test standard, discharges the flue gas after cooling, purifying through chimney (21) through the gravitation that induced draft fan (20) provided, accomplishes the work of the whole set of system.
