Problems solved by technology

[0005] The problem of the prior art is: the free diffusion height H of some powder smoke is too large (usually H=30-100cm), and the powder smoke diffuses randomly in its diffusion space, causing serious pollution; Small (up to H≈1cm), but due to immature principles and technologies, lack of practicality
However, the horizontally placed air suction port and blower port cannot form an ideal shielding surface; the horizontally placed fan also becomes the direct carrier of oil fume; in addition, its structure is bloated and complicated, so it lacks practicality
[0010] In addition, other production facilities (such as chemical reactors; dust processing facilities, etc.) equipped with dust discharge devices also have the disadvantages of large noise, high power consumption, and low effect, which cannot completely solve the pollution problem of powder and dust

Embodiment Construction

[0027] Further description will be made below in conjunction with the accompanying drawings. The fluid envelope type powder and dust shielding and separation discharge device of the present invention is composed of a bracket, a negative pressure wind ring generating device, and a positive pressure wind generating device. The negative pressure wind ring generating device includes a The superior arc-shaped air inlet 2, the positive pressure wind generating device includes a inferior arc-shaped air outlet 1, the air inlet 2 and the air outlet 1 are placed around the diffusion surface 3 of the dipping source; the air inlet 2 is further connected with a wind guide Pipe 4, fan 5 and exhaust pipe 6. The air outlet 1 is inclined to the diffusion surface 3 of the pollution source. Described air outlet 1 shares blower fan 5 with air inlet 2, is connected with the air guide pipe 4 leading to air outlet 1 at the air outlet of blower fan 5, and is shaped on the connecting place of this air...

Abstract

An equipment for shielding separating and exhausting smoke dust is composed of supporting frame, negative-pressure wind ring generator including a major arc-shaped wind inlet, and positive-pressure wind generator including a minor and arc-shaped wine inlet. The wind guide pipe, blower and exhaust pipe are connected with the said wind inlet. Its advantags are high effect, low noise, and compact structure.

Description

technical field [0001] The invention relates to a smoke and dust discharge device, in particular to a fluid envelope type powder and smoke dust shielding and separation discharge device. technical background [0002] With the progress of human civilization, people put forward higher and higher requirements for the quality of production and living environment around them. Correspondingly, some of the existing powder and dust pollution sources do not have a powder and dust discharge device at all; although some are equipped with a corresponding powder and dust discharge device, however, due to various defects in the principle and technology of the existing devices, It is far from meeting people's requirements for production and living environment quality. Powder smoke pollution has been or is endangering people's health. [0003] In the field of daily cooking stoves and range hoods, the shielding, separation and discharge of oil fumes are becoming more and more important due...
