Combinable horizontal pipe type pressure flocculation device

Abstract

The invention discloses a combinable horizontal pipe type pressure flocculation device which comprises a horizontal pipe type pressure-bearing container body; a water inlet and distribution port and a water outlet are respectively formed in the front end and the rear end in the pressure-bearing container body; a plurality of flocculation reaction zones capable of being combined and adjusted are arranged between the water inlet and distribution port and the water outlet; a micro-vortex flocculator is arranged in each flocculation reaction zone; an air hole is formed in the pressure-bearing container body and is positioned above the flocculation reaction zones; the front end and the rear end of the top of the pressure-bearing container body are respectively provided with a first end head which is combined and connected with a dosing and mixing device and a second end head which is combined and connected with a pressure type precipitation device; the top of the pressure-bearing container body is also provided with an upper blowdown system and an automatic intake and exhaust system corresponding to the flocculation reaction zones; and a lower blowdown system is arranged at the bottom of the pressure-bearing container body. The device has the beneficial effects that the device is not limited by the installation position and height, installation is flexible, and the pollution discharge effect is good; water supply energy consumption is saved, and the water supply cost is reduced; the device is not influenced by external wind, light, temperature and other factors, and has no risk of secondary pollution.

Description

technical field [0001] The invention relates to the technical field of water supply and sewage treatment, in particular to a combinable horizontal tube type pressure flocculation device. Background technique [0002] Suspended substances and colloidal particles with small particle sizes in natural water are stable. To remove these substances, coagulation is usually used, that is to say, appropriate coagulants are added to the raw water and mixed quickly and uniformly to stabilize the colloidal particles Under the action of suitable flow rate gradient and coagulant adsorption and bridging, the destabilized colloidal particles will gradually condense into larger flocculent particles, commonly known as "alum flowers", which have the ability to settle or float under the action of gravity, while The purpose of the flocculation tank is to create suitable hydraulic conditions to allow the particles with flocculation properties to aggregate in mutual contact to form larger flocs. ...

AI Technical Summary

Problems solved by technology

[0003] The existing flocculation device operates under gravity flow, and the water head from flocculation to subsequent processes is getting lower and lower. Many water plants are limited by their location and height, and the high water head of the water source (such as a reservoir on a mountain) cannot be fully utilized. , the raw water needs to be depressurized before entering the flocculation process, and the treated water needs to be pressurized again to send water to the pipe network, which consumes a lot of energy and increases the cost of water supply
