Description

technical field [0001] The invention belongs to the field of equipment related to environmental protection treatment, and in particular relates to an intelligent PAM dosing device. Background technique [0002] In the traditional sludge treatment process, because PAM (polyacrylamide) is difficult to dissolve, it is difficult to master the essentials of manual dissolution operation, and it is easy to form flocculation during the dissolution process, and the formation of flocculation in the liquid medicine will affect the normal operation of the dosing system. run. At the same time, the medicament after the formation of flocs cannot be dissolved normally, thereby wasting the medicament and increasing the cost of water treatment. In order to solve the above problems and save labor costs, under normal circumstances, a fully automatic dosing device is used for dosing PAM (polyacrylamide). [0003] PAM automatic dosing device, including PAM automatic dissolving device (dissolvin...

AI Technical Summary

Problems solved by technology

In the past, the addition of flocculants and coagulants was controlled manually. The commonly used flocculant is polyacrylamide, and polyacrylamide can only exert its flocculation effect when it is fully dissolved in water. The dissolution time is about 1 -2 hours, (1) The artificially poured chemical directly enters the sludge in the concentration tank, and the chemical has not been dissolved, and sometimes polyacrylamide will gather at the bottom of the pool to form a cluster, and its flocculation effect has been greatly affected ; (2), manual dosing can not realize the control of the amount, and the size of the dose will also affect the flocculation effect; (3), manual dosing lacks timeliness, and the dosing is not uniform enough

All of the above will ultimately affect the treatment results of water quality.

At present, there are many dosing devices used for dosing in the sludge dehydration treatment process, but they all have the following problems: too many dosing devices, inconvenient operation and management, heavy maintenance workload, and large investment; the overall land occupation of the dosing system The area is huge; and the concentration of the configuration is poor, and the dosage is inaccurate
