Exhaust treatment device for power plant
Technical Field
The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for a power plant.
Background
Industrial pollution refers to the environmental pollution of waste gases, waste waters and solid effluents formed during industrial processes. The pollution is mainly caused by three wastes (waste water, waste gas and waste residue) and various noises in the production. Industrial pollution is mainly concentrated in a few industries. The total amount of discharged wastewater of 7 industries such as paper making, chemical industry, steel, electric power, food, mining, textile and the like accounts for 4/5, and industrial pollution refers to the fact that industrial enterprises infringe natural environments in which organisms including people live and propagate, particularly coal-fired power plants, during production, generated waste gas contains a great amount of particulate matters and is directly discharged into the atmosphere to cause extremely strong damage to the atmospheric environment.
The power plant carries out a series of treatments to the exhaust gas, and the particulate matter among them is just separated at first, and separator generally adopts single filter screen, and the particulate matter of size can be detained in the filter screen through filtering like this, causes the granule on the filter screen to cause the jam problem more easily like this.

In one alternative: the outer side of the ultraviolet lamp is covered with a lampshade.
Compared with the prior art, the invention has the following beneficial effects:
waste gas filters the great dust granule through the filtration pore that the upper filter plate can, then waste gas gets into inside straining the dirt subassembly, waste gas is through the separable wherein most dust granule of filter core, and the dust granule can be detained on the filter screen board of filter core, then waste gas is through the separable less particulate matter of filter screen down again, multiple separation like this, avoid adopting single filter screen and the granule concentrates on it to cause the jam problem fast, and can take out the filter core owing to the setting of dismantling the opening, and when the filter core was taken out, the dust granule that the accessible pulling scraper blade was detained on with the lower filter screen strikes off, and then can effectively clear away the dust granule and strike off in order to prevent to make and block up. The invention has simple structure, can progressively separate particles to avoid the problem of blockage caused by concentration at one position, is convenient to scrape off dust particles and has stronger practicability.
