Mixing device of industrial tail gas purifying agent

Abstract

The invention discloses a mixing device of an industrial tail gas purifying agent. The mixing device comprises a mixing barrel, a liquid outlet pipe and a liquid inlet pipe; the liquid outlet pipe isconnected with the side wall of the bottom end of the mixing barrel through a pipeline; the liquid inlet pipe is connected with the side wall of the top end of the mixing barrel through a pipeline; and the liquid inlet pipe controls liquid pumping through a water pump. A buffer tank is installed between the liquid inlet pipe of the mixing barrel and reagent barrels, and the buffer tank is used forstoring purifying agent solutions pumped from the reagent barrels and carrying out pre-mixing, so that remixing in the mixing barrel is facilitated; a liquid pumping pipe of each reagent barrel is provided with a flow controller, and the flow controllers are used for controlling the flow of the purifying agents in the reagent barrels, so that all the purifying agents can enter the buffer tank according to proportions. Even if one of the flow controllers breaks down, the purifying agent can only be stored in the buffer tank and does not quickly enters the mixing barrel, so that the problem that the proportion of the purifying agents is disordered due to equipment faults can be avoided. The mixing device provided by the invention has the advantage of better mixing effect.

Description

technical field [0001] The invention relates to a mixing device, in particular to a mixing device for an industrial tail gas purifying agent, and belongs to the technical field of tail gas treatment. Background technique [0002] The industrial tail gas is purified by the tail gas treatment device under the action of the catalyst to reduce the pollution to the environment. However, the general purification requires the use of purifiers. Since the proportion of each purifier is different, it needs to be carried out through a mixing device in advance. Mixing, so that the exhaust gas can be purified when it is put into the exhaust gas treatment device. [0003] When each purifier is mixed, a mixing device is used to mix the purifier solution in proportion. When the purifier is drawn out from the reagent tank, it is controlled by the flow controller. Generally, a stirring rod is installed inside the mixing tank to stir and mix the purifier solution. Traditionally The cleaning a...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the time required for the purification agent of the above-mentioned mixing device to be directly put into the mixing tank becomes longer and the input ratio of one of the reagents is out of control, which may easily cause confusion in the solution in the whole tank and affect the exhaust gas purification effect. A mixing device for industrial tail gas purification agent, which has the advantages of high mixing efficiency and avoiding the loss of control of the input amount of purification agent
