Description

Stand-alone dust collector without secondary pollution

technical field

The utility model relates to an improvement of a single-machine dust collector, in particular to a single-machine dust collector without secondary pollution.

Background technique

At present, the stand-alone dust collectors used by enterprises are generally composed of dust collector shells, air inlets, filter devices, dust cleaning facilities for filter devices, induced draft fans, anechoic chambers, dust collection boxes, and vibrators. There are two types of vibrating dust removal and gas back blowing dust removal. In the existing stand-alone dust collector, the dust collected by the dust collector is stored in the dust collection box at the bottom of the dust collector. When the ash level of the dust reaches a certain position, the valve at the bottom of the dust collection box is opened to discharge the dust in the material conveying on equipment such as belts. In terms of dust removal methods, some are directly removed, and some are removed after humidifying the dust through a humidifier. The disadvantage of the above dust removal is that when the dust is directly discharged on the material conveying equipment, the dust can generate huge secondary dust and pollute the environment; at the same time, the dust discharged on the material conveying equipment can cause pollution or damage to subsequent production. Increase the pollution of the post-production dust removal system; if the dust is humidified with a humidifier and then discharged, although the huge dust generated when the dust is discharged is solved, the humidified dust will adhere to the material and material conveying equipment and dry out Finally, secondary pollution is formed on the material conveying equipment and the subsequent production system, and the structure is complex and the investment in equipment is large. Therefore, the stand-alone dust collectors currently used by enterprises cannot completely solve the environmental protection problems to be dealt with.

Contents of the invention

The purpose of the utility model is to provide a stand-alone dust collector without secondary pollution, which can not only effectively solve the secondary pollution, but also has a simple structure and is easy to operate.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the stand-alone dust collector without secondary pollution consists of a dust collector shell, an air inlet, a filter device, a pulsation blowback facility for the filter device, an induced draft fan, an anechoic chamber, Dust collection box, vibrator, intermediate star-shaped ash unloading valve, installation bracket, induced draft fan and filter device are installed in the shell of the dust collector in sequence from top to bottom, the air inlet is set at the lower end of the dust collector shell, and the dust collection box is fixed On the lower opening of the dust collector shell, a vibrator is provided on the outer wall of the ash collection box, and an intermediate star-shaped ash discharge valve is provided on the bottom of the ash collection box. A star-shaped uniform ash discharge valve is installed on the lower port of the low-level material tank. The lower port of the star-shaped uniform ash discharge valve is connected to the pneumatic ash conveying pipeline, and one end of the pneumatic ash conveying pipeline is connected to the power gas source pipeline, and the power gas source pipeline The outer end of the pipe is connected to the external power air source, the other end of the pneumatic ash conveying pipeline is connected to the dust storage bin, and a corresponding vibrator is also installed on the outer wall of the low-level material tank. When the ash in the dust collection box reaches the specified height, the middle star-shaped ash unloading valve will discharge the dust into the low-level material tank in stages, and the dust will be evenly transported from the low-level material tank to the air force through the star-shaped uniform ash unloading valve. Dust is sent into the dust storage bin under the action of the power air source in the ash conveying pipeline, and the star-shaped uniform ash unloading valve at the bottom of the low-level material tank unloads the ash evenly to ensure the normal operation of the pneumatic ash conveying pipeline. An inlet valve group is installed on the source pipeline, and the inlet valve group prevents dust from flowing back into the power gas source pipeline; a low-level material tank is set to isolate the dust collector from the ash unloading device to prevent dust removal caused by lax star valves The interaction between the system and the ash pipeline.

The beneficial effect of the utility model is that: compared with the currently used stand-alone dust collector, since the falling dust is transported to the dust storage bin other than the stand-alone dust collector by adopting the pneumatic ash conveying pipeline, it completely solves the problem that the current stand-alone dust remover is unloading. The problem of secondary pollution caused by falling dust makes the stand-alone dust collector more environmentally friendly and reliable.
