Dust falling and humidifying equipment for concrete production

Abstract

The invention discloses dust falling and humidifying equipment for concrete production, which comprises a purifying barrel, a humidifying barrel, a partition plate, a sealing plate and a draught fan,wherein the humidifying barrel is divided into an upper humidifying cavity and a lower water storage cavity through the partition plate, the sealing plate is movably connected into the humidifying barrel, a through groove is formed in the partition plate, a permeable membrane is fixedly connected into the through groove, a ventilating pipe is fixedly connected into the humidifying barrel, the draught fan is communicated with the ventilating pipe and the purifying barrel, a filter screen is arranged in the purifying barrel, dusty air is extracted through the draught fan, humidified and subjected to static electricity removal in the humidifying cavity, the dusty air is purified in the purifying barrel, an air guide plate and an ultraviolet lamp tube are further arranged in the purifying barrel, and the air guide plate is coated with nano titanium dioxide. The nano titanium dioxide on the air guide plate is irradiated by the ultraviolet lamp tube, so that the toxic gas is catalytically degraded by the nano titanium dioxide.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a dust suppression and humidification device for concrete production. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. Concrete is an essential building material in the construction process of construction projects. [0003] During the construction of large-scale construction projects, the concrete is usually processed in the mixing station, and a large amount of dust will be generated during the concrete preparation process. The dust diffuses and causes pollution to the processing environment. Dust purification treatment, however, the dust in the concrete preparation area is generally formed by dry cement flying, etc., which will ...

Problems solved by technology

[0003] During the construction of large-scale construction projects, the concrete is usually processed in the mixing station, and a large amount of dust will be generated during the concrete preparation process. The dust diffuses and causes pollution to the processing environment. Dust purification treatment, however, the dust in the concrete preparation area is generally formed by dry cement flying, etc., which will absorb moisture in the air, resulting in relatively dry air in the processing environment. When dust is only reduced by means of adsorption or filtration, it cannot Humidification of dry air, overdry air will cause discomfort for workers to inhale, and dry dust is likely to generate a lot of static electricity. Secondly, some harmful gases will be generated during concrete preparation. It is difficult for existing adsorption or filtration methods to remove toxic gases. deal with
