Embodiment Construction
[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0042] In addition, an element in the present invention is said to be "fixed" or "disposed on" another element, and it may be directly on another element or an intervening element may also exist. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purp...

The invention relates to building related equipment, in particular to a e dedusting and purifying device and method for building waste concret. The dedusting and purifying device comprises a liquid tank, wherein a preliminary intercepting mechanism is arranged on one side of the liquid tank; a stirring structure is arranged at the bottom of the liquid tank; a terminal interception structure is arranged on the other side of the liquid tank; a conducting mechanism for uninterruptedly dredging the preliminary intercepting mechanism is arranged below the preliminary intercepting mechanism; a gas pump communicating with the interior of the liquid tank is mounted outside the liquid tank; and the gas pump, the conducting mechanism and the stirring structure are connected with one another. According to the invention, gas is pumped into the liquid tank through the gas pump, and the gas is filtered through the preliminary intercepting mechanism to remove impurities such as plastic wood chips mixed in the gas; then the gas enters adsorption liquid in the liquid tank, and dust contained in the gas and other harmful gas dissolved in the adsorption liquid are absorbed through the adsorption liquid; the stirring structure is used for delaying the flowing speed of gas flow, and prolong the contact time of dust and harmful gas with the adsorption liquid; and finally, the gas is treated by the terminal interception structure.
Description
technical field [0001] The invention relates to construction-related equipment, in particular to a construction waste concrete dust removal and purification device and method. Background technique [0002] Construction waste treatment is a livelihood project. If it is handled well, it can not only turn waste into treasure, but also improve the environment and increase economic benefits. [0003] In the past, construction waste was generally disposed of through landfill, which occupied land and was not easy to decompose; at present, most of them are divided into two-level treatment. The first-level treatment is to crush, sort, and screen construction waste to make graded bricks and stones, which can be applied to the base of the pavement , the water permeability is very good; the corresponding old concrete pavement can be made into recycled sand and gravel aggregate; the secondary treatment can be processed into recycled environmental protection bricks, recycled cement stabil...
