Biomass boiler slag separating machine

Abstract

The invention discloses a biomass boiler slag separating machine which is composed of a tilted string vibration sieve, a ratchet wheel rolling sieve, a fine slag hopper, a coke button hopper, a large biomass block hopper and a protection plate. The string vibration sieve is composed of a flow guide plate, a plurality of tension nuts, a plurality of tension bolts and a plurality of strings. The ratchet wheel rolling sieve is composed of a plurality of ratchet wheels. The fine slag hopper is arranged below the string vibration sieve. The coke button hopper is arranged below the ratchet wheel rolling sieve. The large biomass block hopper is arranged on the lower portion of an outlet of the ratchet wheel rolling sieve. The string vibration sieve is fixed to the ratchet wheel rolling sieve through the protection plate. The biomass boiler slag separating machine has the advantages that fine boiler slag rich in potassium and coke buttons in biomass boiler slag are separated from large biomass blocks and stored in the different hoppers, concentrated landfill processing is carried out on the coke buttons, the landfill cost and landfill conveying cost are saved, large biomass blocks which are insufficiently burned can be fed into a boiler to be burned again, fuel is saved, boiler efficiency is improved, and the fine boiler slag rich in potassium can be used as farmland fertilizer.

Description

technical field [0001] The invention relates to a separation machine, in particular to a separation machine for slag produced by biomass boiler combustion, and belongs to the technical field of particle separation. Background technique [0002] Fossil energy sources such as coal, oil, and natural gas provide energy and power for the development of human society, but also cause great harm to the living environment of humans, such as greenhouse effect, NOx emissions, SO2 emissions, and dust pollution. At the same time, human society is also facing the problem of fossil energy depletion. Therefore, seeking to develop new energy sources and realizing the sustainable development of society has been paid more and more attention by countries all over the world. Biomass energy, as a renewable clean energy, has a good development prospect. The National Academy of Sciences of the United States clearly stated in "Energy Transformation 1985-2010": "By 2010, the energy obtained from la...

Problems solved by technology

Unburned large pieces of biomass fuel will float on the slag pool, and when it accumulates too much, it will prevent the slag from entering the slag pool and affect normal production. Therefore, it needs to be salvaged mechanically or manually, and then put into the boiler for combustion after drying.

The water in the slag pond contains potassium elements leached from the slag, because the enrichment rate is not high enough, it loses its utilization value

[0010] The advantage of this treatment method is that the preliminary separation of slag can be carried out, and the unburned bulk biomass fuel has been reused. The disadvantage is that the potassium element in the slag has not been utilized, and the physical heat of the slag is also lost in vain, and some boiler efficiency
