Description

Steam sweeps energy reduction scrubbing discharging equipment

Technical Field

The utility model relates to the technical field of steam pipeline blowing, in particular to a steam blowing energy-reducing and pollution-removing discharge device.

Background

The pressurized steam system newly constructed in the electromechanical system is easy to cause impurity aggregation in the steam pipeline, metal corrosion, welding slag residue, greasy dirt and other impurities in the whole production process including processing, manufacturing, storage and construction. Therefore, in order to ensure the cleanliness of the steam pipeline system, the pressurized steam system is subjected to purging and debugging before the system is put into use. However, the steam system pipeline in the middle-high-rise building is long in route, the required steam consumption is high in the blowing test, the pressure of the steam is high, the residual quantity of the steam discharged from the tail end is correspondingly increased, a large quantity of white fog can appear at the discharge port, more impurities are blown to the outside under the pressure occasionally, and the residual pressure can cause unsuitable test noise. These problems seriously affect the environment around the building and present a safety hazard.

The prior art mainly includes two major types of means for realizing purging of a steam system, namely pressurizing steam to generate flowing steam in a system pipeline, and flushing impurities, wastes and the like in the pipeline by high-speed movement of the steam. Another common mode is to use the temperature of steam, and the temperature of the pipe rises in the process of gradually heating the steam, and when the heating is stopped, the temperature of the pipe falls, so that oxide skin, adherents, welding slag and the like on the inner wall of the pipe fall off from the pipe body and are blown out of the pipe by the steam. However, one disadvantage of steam purging is that the white steam exhibited by the waste heat of steam tends to cause panic to the surrounding population and nearby residents, even making a suspicion of a fire occurrence, and thus the disposal of the waste heat of steam is an important aspect of steam system purging.

For the treatment of the waste heat of steam, a steam blowing energy dissipation and decontamination discharge device is provided in the patent of China patent No. CN201620101936.8, however, the device has the following defects in use: 1) The control of the liquid level in the water tank is inaccurate, and a set of communicated water tank for observation needs to be additionally arranged; 2) The use is inconvenient, because the scheme needs to be provided with a liquid level observation water tank, the occupied area of the whole set of device is overlarge when the whole set of device is used, and the device cannot be normally used at a position with limited construction site space; 3) The energy reduction effect is to be improved, and the scheme has the phenomenon that the residual energy of steam is not reduced in place in actual use.
