Fire test furnace cooling and purifying system and method

Abstract

The invention discloses and provides fire test furnace cooling and purifying system. The system comprises a fire test furnace flue gas exhaust pipeline. The tail end of the fire test furnace flue gasexhaust pipeline is connected with a water cooling tower. A centrifugal fan is connected to the water cooling tower and connected with at least one drying oven group. The drying oven group is connected with an electrostatic dust collector through a pipeline. The electrostatic dust collector is connected to a high chimney. The system further comprises a master controller. The master controller mainly acquires parameter data and flue gas data of the water cooling tower, the centrifugal fan, the drying oven group and the electrostatic dust collector and performs flue gas purifying comprehensive control according to acquired parameters. According to the fire test furnace cooling and purifying system, flue gas is cooled and purified before being exhausted; and meanwhile, by controlling and regulating pressure in a fire test furnace and the flue gas exhaust pipeline, the atmospheric pollution is reduced, the concept of energy saving and environment protection is achieved, and furthermore, safe operation of the fire test furnace is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of flue gas purification, in particular to a cooling and purification system and method for a fire test furnace. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The increasing number of building fires has made people pay more and more attention to the performance changes of building structures under fire and the resulting hazards. Using fire test furnaces to study structural fire resistance is one of the main methods adopted. However, the current smoke exhaust system of the fire test furnace is relatively simple, and lacks devices for cooling the flue gas, purifying the pollution, and controlling the pressure. [0004] The inventors of the present disclosure have found that the current smoke exhaust system for fire test furnaces has the following problems: (1) ...

However, the current smoke exhaust system of the fire test furnace is relatively simple, and lacks devices for cooling the flue gas, purifying the pollution, and controlling the pressure

[0004] The inventors of the present disclosure have found that the current smoke exhaust system for fire test furnaces has the following problems: (1) Most of the existing fire test furnaces directly discharge the smoke through chimneys built outside, and the smoke is discharged through the chimney without cooling treatment. (2) The structure of the smoke exhaust system is simple, only through the shutter installed at the exit of the flue to adjust the furnace temperature and furnace pressure, and cannot effectively control the furnace and smoke exhaust The pressure in the pipeline and the fire test furnace will pollute the environment, which mainly comes from the random discharge of smoke
