Embodiment 1

[0019] Such as figure 1 Shown, a kind of ammonium metavanadate solution automatic delivery method comprises the steps:

[0020] 1. Add ion-free water to the ammonium metavanadate dissolving tank to ensure that the dissolving tank is not polluted, and at the same time confirm that the outlet valve of ammonium metavanadate is closed, the exhaust valve of the ammonium metavanadate preparation tank is normally open, and the compressed air inlet valve is closed;

[0021] 2. Add "No. 3" additive monoethanolamine to the ammonium metavanadate dissolution tank, and add monoethanolamine to form a buffer solution to prepare for dissolving ammonium metavanadate; ammonium metavanadate is insoluble in water and easily soluble in alkali;

[0022] 3. Start the agitator of the ammonium metavanadate dissolution tank and start the heating device at the same time;

[0023] 4. When the heating temperature is displayed as 90°C, add the "No. 2" additive ammonium metavanadate to prepare the active m...

Abstract

The invention discloses an automatic conveying method for ammonium metavanadate solution. A compressed air source is introduced by an exhaust hole in an ammonium metavanadate solution configuration kettle, a buffer tank is additionally arranged, a process pipeline is installed from the bottom of the configuration kettle to the buffer tank, a pipeline is installed from the buffer tank to an inlet of a metering pump, and the ammonium metavanadate solution is sent to a mixing machine through the metering pump. The method has the advantages that sealing and conveying of the ammonium metavanadate solution are realized, personnel contact is reduced, and occupational health and ecological environment of workers are protected; and the labor intensity of workers is reduced; and the adding amount ismore accurate during the material mixing process.

Description

technical field [0001] The invention relates to an airtight delivery method of chemical solution, in particular to an automatic delivery method of ammonium metavanadate solution in the production process of SCR flue gas denitrification catalyst, and belongs to the field of delivery method of chemical solution. Background technique [0002] In the production process of SCR denitration catalyst, the configuration of ammonium metavanadate solution belongs to an independent production unit. Ammonium metavanadate is a poison that has multiple effects on the body, and can cause changes in blood circulation, respiratory organs, nervous system, metabolism, etc. At present, the configuration units of ammonium metavanadate solution are extensive and simple, which affects the occupational health of personnel and the ecological environment. Contents of the invention [0003] In order to solve the above problems, the present invention designs an automatic delivery method for ammonium ...
