Boiler ammoniating device

Abstract

The invention provides a boiler ammoniating device. An ammonia pressure reducer is arranged on an ammonia cylinder; an inlet and an outlet of the ammonia pressure reducer are provided with pressure gauges; the ammonia pressure reducer is also provided with an ammonia pressure reducer outlet valve which is connected with an ammonia inlet valve of an ammonia dissolution metering device through a pipeline; the dissolution metering device is a tank body, the top of the tank body is respectively provided with a desalted water inlet, an ammonia water inlet and an ammonia gas outlet, and the bottom of the tank body is provided with an ammonia water outlet which is connected with a product water delivery pump suction port through an ammoniating pump inlet valve and a metering pump; the ammonia gas outlet at the upper part of the ammonia dissolution metering device is connected with an ammonia absorber through a volatile gas pipeline; the absorber is also a tank body, the upper part of the ammonia absorber is provided with a raw water inlet connected with a raw water valve, the top of the ammonia absorber is provided with an ammonia gas outlet of the ammonia absorber, the middle of the ammonia absorber is provided with an ammonia absorption device, the bottom of the ammonia absorber is provided with a drain outlet of the ammonia absorber, and the drain outlet is connected with a pipeline through a drain valve of the ammonia absorber. The ammoniating device is used for converting liquid ammonia into ammonia water and is incapable of escaping irritant ammoniacal smell and generating hazards to the environment and human bodies and capable of avoiding occupational diseases to the maximum extent. The device is low in operation cost, safe and easy to operate.

Description

technical field [0001] The invention relates to a treatment device for adjusting PH of boiler feed water, in particular to a boiler ammonia adding device. Background technique [0002] After the boiler feed water membrane treatment, the water is acidic and the PH value is low. If such water is directly added to the boiler, it will cause CO 2 Corrosion, need to adjust the pH value to 8 ~ 9.2. Use the alkalinity of ammonia to neutralize residual CO 2 The formed acidity does not increase the salinity of the boiler feed water, so adding ammonia is the best way to increase the PH value of the boiler feed water. [0003] The existing ammonia addition equipment is mainly to directly add ammonia water. Since the deployment and dosing of the added ammonia water are carried out in an incompletely sealed environment, it will cause a strong pungent smell on the scene of the ammonia addition water, which will cause great damage to the operators. , can lead to the occurrence of occupat...
