Lime milk distribution and regulation dosing system

Abstract

The invention discloses a lime milk distribution and regulation dosing system, which comprises a lime powder conveying system, a lime storage and metering system and a lime milk conveying and preparing system, wherein the lime powder conveying system comprises a lime material bin which is connected with a lime transport vehicle through an inlet valve of the lime material bin; the lime storage and metering system comprises a lime metering barrel; the lime milk conveying and preparing system comprises a quantitative lime milk preparation box and a lime milk conveying pump; a pneumatic vibrator is arranged in the lime material bin; the quantitative lime milk preparation box is divided into upper and lower chambers; the upper chamber is a metering and preparing chamber and the lower chamber is a lime stirring chamber; a spraying water inlet valve and a sewage drainage valve are arranged on the quantitative lime milk preparation box; a tee distribution and regulation valve is arranged at the outlet of the lime milk conveying and preparing system. According to the lime milk distribution and regulation dosing system, pipelines and the valves are unlikely to get blocked and no ash leaks; meanwhile, the preparing concentration and low cost of lime milk can be well guaranteed.

Description

technical field [0001] The invention relates to a lime metering device, in particular to a lime milk dosing system for split flow adjustment, which is especially suitable for lime dosing in reclaimed water reuse systems, circulating cooling water treatment systems, desulfurization wastewater treatment systems, etc. medicine system. Background technique [0002] At present, there are two kinds of lime metering systems used in the chemical treatment water engineering of power plants, dry method and wet method metering system. The principle of dry lime metering is to use the amount of water in the system and the amount of dry lime to be added according to a certain ratio to ensure that the pH in the clarifier behind is stable. The specific equipment includes: lime silo, vibrating hopper, manual slide valve, star feeder Material machine, screw conveyor, gas powder separator, balance water tank, lime mixing tank, lime milk delivery pump, also includes supporting valves and contr...

AI Technical Summary

Problems solved by technology

The system works well, but there are still problems. The main problems are: 1. The metering bucket is also easy to block, especially during the initial feeding, the vibration effect of the vibration motor is poor, and it is difficult to feed.

2. The cost of the overall equipment is relatively high, and there are many valves and equipment. Because the preparation box needs to be measured according to the volume, the preparation box and the mixing box are calculated to be larger and higher in height, resulting in a higher overall height of the workshop and a higher engineering total. Higher cost

The biggest problem is the high cost
