A gas spray cooling system in front of the gas cabinet

Abstract

The invention provides a gas spray cooling system arranged in front of a gas holder, and belongs to the technical field of the gas holder and pipeline projects. The system comprises the gas holder, a gas pipeline outside the gas holder and a gas spray cooling device; the gas holder comprises a cylinder body and a gas pipeline inside the gas holder; and the gas spray cooling device comprises a plurality of sets of spray guns, a PLC frequency conversion control cabinet and a gas thermometer inside the gas holder, and the gas thermometer inside the gas holder is arranged at the lower part of the cylinder body of the gas holder, is electrically connected to the PLC frequency conversion control cabinet and is used for monitoring the temperature of gas in the gas holder and participating in start and stop control over the gas spray cooling device. According to the system, a monitoring point of the temperature of the gas in the gas holder is additionally arranged, the gas spray cooling device is started when the temperature in the gas holder exceeds a set value, and therefore the potential mixing and cooling function and the heat dissipation ability of the gas holder are given full play to. The system is of great significance for saving energy and lowering consumption of iron and steel enterprises and prolonging the service life of sealing oil of the gas holder.

Description

technical field [0001] The invention belongs to the technical field of gas cabinets and pipeline engineering, and in particular relates to a blast furnace gas spray cooling system applied in front of blast furnace gas cabinets in the iron and steel industry. Background technique [0002] The pipeline gas spray cooling system is generally composed of spray guns, thermometers and other detection and control instruments, collective pump stations, independent PLC frequency conversion control cabinets, and various pipelines. The size of the difference determines the number of spray guns to open, and then according to the difference between the actual outlet temperature after the gas is cooled and the set target temperature, the frequency converter adjusts the motor speed, adjusts the water supply flow of the water pump and the corresponding number of spray guns to open, and dynamically adjusts the outlet temperature , so that the outlet temperature is stabilized within the set ta...

AI Technical Summary

Problems solved by technology

[0005] There are obvious shortcomings in the existing technology. Although the flow rate of the incoming gas is not large, once the set temperature is exceeded, the spray cooling system will start, and the spray guns of the spray cooling system are started in groups according to the outlet temperature, and the mixing of the gas cabinet is not fully utilized. Function and heat dissipation capacity, this will not only cause waste of water resources, increase in water treatment costs or power loss, frequent start and stop of the spray cooling system, etc., but also cause gas cabinet sealing oil additives to lose quickly with the loss of gas condensate, gas cabinet sealing oil spoilage speed up etc.
