On-line dynamic and static mixer

Abstract

The invention provides an on-line dynamic and static mixer which is provided with a barrel; a liquid inlet is formed in the front end of the barrel, and a mixing outlet is formed in the rear end of the barrel; an injection conduit is designed to extend into the barrel to be close to the front end from the radial side surface of the barrel, and the outer end of the injection conduit is provided with a medium inlet; a distributor is provided with a plurality of guide pipes arranged in a radial shape, the outer ends of the guide pipes are closed, the inner ends of the guide pipes are communicatedwith the injection conduit, and a plurality of spray holes are formed in the side wall of each guide pipe; a mixing internal part is arranged in the barrel at the downstream of the distributor; stirring blades are fixed in the barrel at the downstream of the mixing internal part, and a rotating shaft of the stirring blades is designed to extend out of the barrel along the radial direction and isconnected with a motor; the flow velocity detector is installed at the position, close to a liquid flow inlet, in the barrel and is in signal connection with the motor. The distributor, the mixing internal part and the stirring blades are adopted, so that a static mixer and a dynamic mixer are integrated, and the mixing efficiency is improved.

Description

technical field [0001] The invention relates to a mixer structure used in sludge treatment, which is also applicable to the mixing of other media. Background technique [0002] Sludge treatment is a very critical part of oilfield sewage treatment. With the increasingly stringent environmental protection requirements, the harmless and efficient sludge treatment has become an inevitable trend. Sludge dehydration is the premise of sludge treatment. Reducing the moisture content of sludge can effectively reduce the load and treatment difficulty of subsequent sludge treatment equipment, and significantly reduce the cost of sludge treatment. Online fast mixer is the key equipment for mixing sludge and chemicals. [0003] Online fast mixers are divided into static type and dynamic type according to whether external energy supply is required. The static mixer is through the special pipeline structure in the mixer, so that when the liquid flow passes through, there will be three fu...

Problems solved by technology

[0004] However, the static mixer mixes the medium through the pipeline structure, which is only suitable for the case of fast flow rate. When the flow rate is slow, the mixing effect is poor and the automatic adjustment performance is poor; while the dynamic mixer has poor rectification effect on the medium and consumes a lot of energy.
