Problems solved by technology

Its shortcomings: first, the vacuum cleaner is a household vacuum cleaner, which cannot be used with a sander; second, the siphon flow is a damping change structure, and the air diffusion cavity cannot be formed in the structural design, so the free fall of dust cannot be realized. Large wind resistance, high energy consumption, and poor filtration and purification effects, it cannot be used for industrial vacuuming and purification at all
Its disadvantages: when it encounters high-temperature dust particles or burning dust particles, it will catch fire and burn, so it is impossible to filter and purify the gas entrained with high-temperature dust particles and high-temperature combustion dust particles
Its shortcoming: it can only remove the large particles in the dust, but cannot effectively filter the tiny dust

Embodiment 1

[0012] Embodiment 1: with reference to attached figure 1 . For the wet vacuum cleaner, the centrifugal fan 1 is purchased or processed and is located at the upper part of the inner body 9 of the machine. The labyrinth water retaining mechanism 3 is composed of two or more sets of labyrinth water retaining assemblies, which are stacked at an upper and lower interval. Each group of labyrinth water retaining assemblies is composed of a water retaining plate 5 and a guide plate 4. The trapezoidal structure is processed and formed by the prior art, and the guide plate 4 is trumpet-shaped and processed by the prior art. The guide plate 4 is located above the water baffle 5 and cooperates with the water baffle 5 at a distance. The distance is generally between 2 and 10 cm and depends on the power of the wet vacuum cleaner. The labyrinth water retaining mechanism 3 is located (installed) in the machine body 9 and below the centrifugal fan 1, and the labyrinth water retaining mechani...

Embodiment 2

[0013] Embodiment 2: On the basis of Embodiment 1, the labyrinth water retaining mechanism 3 is composed of a group of labyrinth water retaining assemblies.

Embodiment 3

[0014] Embodiment 3: On the basis of Embodiment 1 or 1 and 2, start the centrifugal fan 1, and under the action of the centrifugal fan 1, pass through the negative pressure area of ​​the labyrinth water retaining mechanism 3, the reservoir 7, and the air diffusion chamber 10, The air inlet 11 forms a high-pressure negative pressure zone, and the high-temperature dust (combustion particles) air or high-temperature dust (combustion particles) airflow to be dedusted is sucked into the airflow diffusion chamber 10, and the high-temperature dust airflow enters the airflow diffusion chamber from the air inlet 11 10, because the space of the airflow diffusion chamber 10 is much larger than the space of the air inlet, the high-pressure and high-temperature dust airflow entering the airflow diffusion chamber 10 loses pressure instantly and the flow velocity decreases, and the dust entrained in the high-temperature dust airflow is affected by its own weight. And the effect of the earth's...

Abstract

The invention relates to a filter purification method which can lead the gas which contains high-temperature dust grains and high-temperature combustion dust grains to pass through a wet-typed dust arrester and be filtrated, so as to lead the gas to be converted into dustless and clean gas and lead the gas to be guided to the filter water accumulation pool; under the action of a centrifugal fan, the negative pressure passes through a labyrinth-typed water retaining mechanism, the water accumulation pool and an airflow diffusion chamber so as to lead the wind inlet to form a high-pressure negative pressure area; when the high-temperature dust gas to be dedusted is sucked into the airflow diffusion chamber, the high-temperature dust airflow loses the pressure and the flowing speed is reduced, therefore, the dust grains contained in high-temperature dust airflow drips in the water accumulation pool; the airflow which loses the pressure and the dust grains increases the pressure and rapidly passes through the water surface when passing through the airflow passage which consists of a lower end of the internal machine wall and the lower end surface of the external machine body; the water in the airflow is damped and drips in the water accumulation pool by the labyrinth-typed water retaining mechanism; the purified airflow passes through the labyrinth-typed water retaining mechanism and the centrifugal fan and is exhausted into the atmosphere by the wind outlet.

Description

technical field [0001] The invention relates to a kind of gas that can carry high-temperature dust particles and high-temperature combustion dust particles and can be converted into dust-free and clean gas after being filtered by a wet vacuum cleaner. , Wet vacuum cleaner manufacturing field for filtering and purifying high-temperature combustion dust particles. Background technique [0002] The authorized announcement number is CN2224593Y, and the name is "high-efficiency water filter vacuum cleaner". This water filter vacuum cleaner replaces the dust storage chamber and filter screen in the existing vacuum cleaner with a water filter device. Wherein the water filtering device is composed of a suction pipe, a bottom shell, a buried water broken bubble baffle, a labyrinth water baffle and water. The structure of the buried water broken bubble baffle is mesopore steam structure, while the labyrinth water baffle is a ring wall groove structure. Its shortcomings: first, the...
