Description

Cyclone dust collector without tower body

technical field

The invention relates to the technical field of purification equipment, in particular to a cyclone dust collector without a tower body.

Background technique

Exhaust gas is poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health.

The exhaust gas is generally mixed with dust. When the exhaust gas is treated, the dust is first absorbed by the dust removal tower, and then the harmful gas is treated by the purification device, and finally the purification is achieved. The traditional dust removal tower is tower-shaped and has a complex structure, which leads to relatively high costs.

Contents of the invention

In order to solve the technical problems in the background technology, the invention discloses a cyclone dust collector without a tower body.

The invention provides a cyclone dust collector without a tower body, comprising:

Pipelines arranged in a serpentine shape;

The water tank sprays water into the pipeline through a plurality of water inlet pipes, and returns the water in the pipeline through a plurality of water return pipes.

The pipeline is designed in a serpentine shape, which prolongs the path of exhaust gas and the contact time between exhaust gas and water, so that the dust in the exhaust gas can fully contact with water, and the purpose of fully exhausting dust is realized. The dust flows into the water tank with the water flow; the invention not only The structure is simple, and the traditional tower structure is canceled, thereby reducing the cost.

If the water is sprayed directly, not only the water utilization rate is low, but also the contact with the exhaust gas is insufficient, and the dust removal efficiency is not high, so further improvement is made to solve this problem. Specifically, an atomizing nozzle is provided at the outlet of the water inlet pipe. Atomizing nozzles spray water in the form of mist.

Since the water mist is sprayed in a directional manner, when the exhaust gas passes through, the full contact effect cannot be achieved, so further improvements are made to solve this problem. Specifically, a fan is installed at the entrance of the pipeline. The fan blows the exhaust gas and water mist, so that the exhaust gas and water mist collide and contact, thereby improving the contact effect and improving the dust removal efficiency.

Due to the small area of the inner wall of the pipe, the contact area of the exhaust gas is small, and the dust removal and filtration is not high, so further improvement is made to solve this problem. Specifically, a plurality of protruding convex plates are arranged in the pipe. The setting of the convex plate increases the area where the water mist adheres, thereby increasing the area where the exhaust gas contacts and improving the dust removal rate.

If the convex plates are randomly arranged, the flow direction in the pipeline will be disordered, the flow velocity will be slow, and the contact effect will be reduced. Therefore, this problem is further improved. Specifically, the convex plates are distributed in a spiral shape. With this arrangement, the exhaust gas flows in a helical direction in the pipeline, not only the flow velocity is increased, but the contact effect is also improved.

The installation positions of the water inlet and outlet pipes are various. Based on this, the further design is: the water inlet pipe is connected to the upper part of the pipe, and the return pipe is connected to the bottom of the pipe. The position of the water inlet pipe is set so that the water mist can cover a larger area under the action of gravity; the position of the return water pipe is set so that the accumulated water mixed with dust in the pipe can all flow into the water tank.

In order to prevent the water in the water inlet pipe from being mixed with dust and affect the dust removal effect, in this solution, a filter is also installed on the water tank, and the return pipe is connected to the inlet of the filter after converging.

detailed description

The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

Embodiment one:

The water tank 2 is provided with a water pump 7, the outlet of the water pump 7 is connected with a main water outlet pipe, and the main water outlet pipe is connected in parallel with a plurality of water inlet pipes 21, which are respectively connected with each vertically arranged pipeline 1.

The pipeline 1 is also provided with a plurality of parallel return pipes 22 , which flow back into the water tank 2 after being filtered by the filter 5 after passing through the main return pipe. The filter 5 is used to prevent the water in the water inlet pipe 21 from being mixed with dust, which will affect the dust removal effect.

The pipe 1 is designed in a serpentine shape, which prolongs the passage of the exhaust gas and the contact time between the exhaust gas and water, so that the dust in the exhaust gas can fully contact with the water to achieve the purpose of fully exhausting the dust, and the dust flows into the water tank 2 following the water flow; The invention not only has a simple structure, but also cancels the traditional tower structure, thereby reducing the cost.
