Abstract

The invention relates to a closed ammonia adding device for water supply in a chemical water furnace. The device comprises a chemical water furnace, an ammonia water tank, a liquid ammonia storage tank and a water storage tank, the liquid ammonia storage tank is connected with the ammonia water tank through a first pipeline, the water storage tank is connected with the ammonia water tank through a second pipeline, the ammonia water tank is provided with an ammonia water outlet pipe connected with the chemical water furnace, and the ammonia water outlet pipe is provided with a metering valve. A metering pump is arranged on the ammonia water outlet pipe, a first switch valve and a second switch valve are arranged on the first pipeline and the second pipeline respectively, meters are arranged on the first pipeline and the second pipeline respectively, and valve rods of the first switch valve and the second switch valve are provided with a first driven gear and a second driven gear respectively. A driving mechanism for driving the first driven gear and the second driven gear to rotate in the same direction or opposite directions is arranged between the first switch valve and the second switch valve. According to the ammonia adding device, liquid ammonia and water are converted into ammonia water in the closed container, closed feeding of the ammonia water is achieved, and harm to the environment and health of workers caused by volatile ammonia gas is reduced.

Description

technical field [0001] The present application relates to the technical field of ammonia adding devices, in particular to a water feed closed type ammonia adding device in a water furnace. Background technique [0002] After the treatment of the water feed water film method of the chemical water furnace, the water is acidic and the pH value is lowered. At this time, the water directly added to the knife chemical water furnace will cause corrosion of the water supply pipeline and the thermal system, and the pH value needs to be adjusted. Adding ammonia is the best way to increase the pH value of the feed water of the water boiler. The alkalinity of the ammonia used neutralizes the acidity of the water. [0003] At present, when adding ammonia to the water in the water furnace, the personnel manually pour it into the water furnace when it is used. The ammonia itself is volatile. During the process of transporting the ammonia water to the storage tank, a large amount of ammonia...
