Circulating liquid PH intelligent control device for ammonium sulfate production

Abstract

The invention discloses a circulating liquid PH intelligent control device for ammonium sulfate production, the circulating liquid PH intelligent control device comprises a bottom plate and a flow adjusting mechanism, an acid storage container is arranged at the top end of the bottom plate, a circulating liquid full-flow device is arranged on one side, away from the acid storage container, of the bottom plate, and a fixing frame is arranged on one side of the acid storage container; an acid pump is arranged at the bottom end of the fixing frame, the input end of the acid pump is connected with an acid storage container, the output end of the acid pump is provided with a conveying pipe connected with the input end of the circulating liquid full-flow device, an acid adding frame penetrating through the fixing frame is arranged at the top end of the conveying pipe, and a quantifying mechanism used for controlling the acid adding amount is arranged in the acid adding frame. A first valve is arranged on the outer wall of the conveying pipe, and a flow adjusting mechanism used for controlling flow is arranged on the side, close to the circulating liquid full-flow device, of the conveying pipe. By adjusting the opening degree of the flow adjusting mechanism, it is ensured that the PH value of the circulating liquid is always controlled within the specified range, and therefore intelligent control over the circulating liquid is achieved.

Description

technical field [0001] The invention belongs to the field of ammonium sulfate production devices, and more specifically, the invention relates to a circulating liquid pH intelligent control device for ammonium sulfate production. Background technique [0002] At present, the ammonium sulfate post in domestic coking plants is still manual operation for adding acid to mother liquor, and there are the following drawbacks in the operation process: 1. The operator needs to sample and analyze the acidity of the mother liquor every 30 minutes. It takes 10 minutes for sampling and analysis. The frequency of sampling and analysis is high and labor-intensive. At the same time, it is possible to inhale harmful gases such as ammonia and carbon monoxide during sampling, which will cause harm to the physical and mental health of employees. 2. There is a risk of acid burns when the operator adjusts the acid suspension valve. 3. It is impossible to add acid quantitatively, and it is easy t...

Problems solved by technology

[0002] At present, the ammonium sulfate post in the domestic coking plant is still manually operating the mother liquor acid addition operation, and there are the following disadvantages in the operation process: 1. The operator needs to sample and analyze the acidity of the mother liquor every 30 minutes. Sampling and analysis takes 10 minutes. The frequency of sampling and analysis is high and the labor intensity is high. At the same time, harmful gases such as ammonia and carbon monoxide may be inhaled during sampling, which will cause damage to the physical and mental health of employees.

2. There is a risk of acid burns when the operator adjusts the acid valve

3. It is impossible to add acid quantitatively, and the amount of acid added is prone to be uncertain, which in turn affects production efficiency
