Description

Dust-collecting environment-friendly mechanical equipment

Technical Field

The invention relates to the field of environmental protection, in particular to environment-friendly dust collection mechanical equipment.

Background

The boiler waste gas treatment process mainly adopts a dust removal method and a water absorption method. The boilers used by enterprises are mainly biomass boilers and coal-fired boilers, and the pollution of the biomass boilers to the environment is less than that of the coal-fired boilers. The main components of the boiler exhaust gas are nitrogen oxides, sulfur dioxide, carbon dioxide, sulfur oxides, smoke (dust), fly ash and the like, and if the boiler exhaust gas is not treated and is directly discharged into the air, the boiler exhaust gas can cause severe pollution to the air, so the boiler exhaust gas can be discharged into the air only after being treated by the exhaust gas.

The waste gas treatment of the boiler generally adopts a bag-type dust remover, and the bag-type dust remover has several problems in dust removal.

1. The boiler dust contains sticky components such as carbon black and the like, so that sticky bags are easily caused.

2. The biomass boiler dust is fine, and the biomass boiler dust is easy to carry small blocks and carbides which are not fully combusted, so that secondary combustion is easy to generate.

3. There is a phenomenon of diffusion.

4. Aiming at the analysis of the components of the waste gas of the biomass boiler and the analysis of the ash generated by combustion, the ash content in the analysis of the components of the flue gas is about 8 percent, the ash content in S, CI is respectively 0.22 percent and 0.6 percent, the proportion of the alkaline substances such as MgO, CaO, Na2O, K2O and the like in the plant ash in the ash is up to 30 percent, namely the removal of the substances such as SO2, HCI, HF and the like in the flue gas can be realized by utilizing the conditions of humidifying, activating and fully mixing the alkaline substances in the plant ash,

5. the components of the waste gas of the boiler are complex, a proper process is selected according to the field condition in the actual treatment process, and most of the subsequent components of the process treatment need to be firstly fixed and firstly treated, so that the subsequent removal of the chemical pollution components of the flue gas is facilitated.

Waste water is one of the main resources of cyclic utilization that need handle in the industry, and waste water needs to add the flocculating agent after the prefiltering to carry out flocculation aquatic suspended solid, then discharges into the flocculation basin, carries out subsequent processing and purifies again, gets into subsequent recycle.
