New ammonia water storage device

Abstract

The invention discloses a novel ammonium hydroxide storage device. The part, above the liquid level of ammonium hydroxide, of a tank is connected with a transparent U-shaped linkage device, and the transparent U-shaped linkage device is connected with a controller through an upper liquid level electrode and a lower liquid level electrode. An annular spraying tube is arranged above the tank in a communicated mode and communicated with a water inlet valve through a solenoid valve. The water inlet valve is connected with a water tank through a float ball valve, and the water tank is communicated with the tank through an electrically operated valve and a common valve. The controller is provided with a control cable and connected with the solenoid valve and the electrically operated valve through the control cable, and controls the solenoid valve and the electrically operated valve to be opened and closed. The novel ammonium hydroxide storage device is ingenious and simple in structural design, the differential pressure inside and outside the tank is used for driving the liquid level of the transparent U-type linkage device to perform electrode sensing control, and different measures are adopted for achieving the purposes of safety, warning, energy saving and emission reducing; a closed circuit system is free of losses and pollution and low in water consumption, and therefore the purpose that ammonium hydroxide is stored safely and effectively in a quality-guaranteeing mode; the device is reliable, low in cost and labor intensity and operates automatically and efficiently.

Description

technical field [0001] The invention relates to a novel ammonia water storage device, which belongs to the field of chemical machinery. Background technique [0002] Ammonia storage is an indispensable unit operation in many chemical productions. For example, the electrolytic manganese industry needs to consume a large amount of ammonia. Ammonia storage is generally carried out in a dedicated ammonia storage device. [0003] However, ordinary ammonia water storage tanks inevitably volatilize during the storage of ammonia water. When the temperature is high, the volatilization is serious, thereby reducing the concentration of ammonia water and causing losses, which also affects the use of the process. Ammonia volatilization in a small environment is highly corrosive to equipment, highly irritating to humans, and pollutes the environment. Although there are some recovery devices designed for this situation at present, they need manual inspection and control frequently, and ca...

Problems solved by technology

[0003] However, ordinary ammonia water storage tanks inevitably volatilize during the storage of ammonia water. When the temperature is high, the volatilization is serious, thereby reducing the concentration of ammonia water and causing losses, which also affects the use of the process.

Ammonia volatilization in a small environment is highly corrosive to equipment, highly irritating to humans, and pollutes the environment

Although there are some recovery devices designed for this situation at present, they need manual inspection and control frequently, and cannot realize automatic, accurate and timely recovery and treatment of the volatilized ammonia gas

[0004] Therefore, the existing ammonia water storage device cannot adapt to the requirements of modern production and needs to be improved
