Abstract

The utility model discloses a steam boiler smoke dust filtration device for biomass fuel, which comprises a box body and a water spray rack arranged in the box body, wherein a smoke removal passage is formed in the bottom of the box body; a reversed V-shaped big water spray rack is arranged at a water inlet in the upper part of the box body; reversed V-shaped small water spray racks and a V-shaped grooves are formed in the lower part of the big water spray rack; the top edge of the V-shaped groove fixed on the side wall of the box body is positioned at the top of the small water spray racks; the bottom end of the V-shaped groove is positioned at the upper part of the smoke removal passage; a water spray mesh is formed in the bottom end of the v-shaped groove; and the water flow of the water spray mesh leads to the smoke removal passage. The device has the advantages that the filtering process of discharging smoke dust is simplified; higher energy conservation and emission reduction efficiency are provided; the structure of the water spray filtering box is practical, simple and convenient; the mounting and the use are convenient; water is taken as the medium for cleaning smoke dust; the cost is low; the efficiency is high; the recycling of the discharge material such as soot to be taken as fertilizer to recycle is more thorough; the energy consumption is low; recycling pumping electrical equipment is only needed to be mounted; the water is saved and circularly used; and no discharge is needed.

Description

The boiler smoke filter

Technical field

The utility model relates to environmental protection equipment, and particularly steam boiler is to the boiler smoke filter of flue dust that biomass fuel combustion produces.

Background technology

In steam boiler, generally adopt professional dedusters such as dust removal with machine, electrostatic precipitation at present.Now existing straw and the rice husk used is as boiler oil, bag dust collector is widely used in purifying ash-laden gas, ash-laden gas after burning filter bag outer surface from sack cleaner under the effect of air-introduced machine penetrates in the filter bag, the dusty material that contains in the flue gas in this process is filtered the outer surface that accumulates in filter bag by filter bag, makes discharged flue gas meet standard.But because the particle of straw and rice husk burning back flying dust is thin, quality is light, and moisture content is high, adopt conventional bag dust collector to capture and just have certain difficulty, especially after boiler is used biomass fuel instead, because therefore the change of technology needs the more simple and practical soot emissions scavenge unit of design.

The utility model content

The utility model designs a kind of boiler smoke filter of trickle filter type at the filtering of discharging flue dust in the firing biomass fuel.

The utility model is between soot emissions channel outlet and chimney, and trickle Rose Box of design and installation makes the flue dust of burning and exhausting through this device, realizes filtering and the recovery of flue dust.For addressing the above problem the concrete technical scheme that proposes be: a kind of boiler smoke filter, the trickle frame that comprises casing and place casing, it is characterized in that: the bottom at casing is provided with discharge flue, be provided with the big trickle frame of ∧ shape in water inlet, casing top, below big trickle frame, be provided with the little trickle frame of ∧ shape and v-depression; Be fixed on the top of the v-depression on the wall box along the top that is positioned at little trickle frame, the bottom of v-depression is positioned at the top of discharge flue; The v-depression bottom has the trickle mesh, and the current of trickle mesh lead to discharge flue.

The interior angle of the big trickle frame of described ∧ shape is 100～150 °, and the internal angle beta of the little trickle frame of ∧ shape is 80～120 °.

The utility model compared with prior art has following advantage: 1, simplified the filter process of discharging flue dust, possessed higher energy-saving and emission-reduction efficient, it is low to consume energy, and only need install back with the power equipment that draws water; 2, trickle Rose Box structure practical simplicity is easy to install and use; 3, adopt water to do the medium of removing flue dust, cost is low, the efficient height; 4, emission such as cigarette ash reclaim more thorough, can be as the fertilizer recycling; 5, using water wisely, water circulation use need not discharging.

Description of drawings

Fig. 1 is the utility model generalized section.

Fig. 2 be among Fig. 1 A-A to generalized section.

Among the figure: 1 water inlet, 2 casings, 3 discharge flues, 4 big trickle framves, 5 little trickle framves, 6 delivery ports, 7 trickle meshes, 8 grooves.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is installed on the discharge flue of biomass fuel boiler, the Rose Box of this device is designed to rectangle casing 2, be provided with water inlet 1 at the casing top, bottom half be provided with delivery port 6, constitute a complete water circulation channel by water inlet 1 and delivery port 6, circulation pump drainage water lines and discharge water water purification reuse storage tank, make the discharge water that cleans flue dust purify the back recycling.Be provided with discharge flue 3 in the bottom of casing 2, be provided with the big trickle frame 4 of ∧ shape at casing top water inlet 1 place, below big trickle frame 4, be provided with the little trickle frame 5 of ∧ shape and v-depression 8, the interior angle of the big trickle frame 4 of ∧ shape is designed to 100～150 °, and the internal angle beta of the little trickle frame 5 of ∧ shape is designed to 80～120 °.Be fixed on the top of the v-depression 8 on the wall box along the top that is positioned at little trickle frame 5, the bottom of v-depression is positioned at the top of discharge flue; The v-depression bottom has trickle mesh 7, and the current of trickle mesh 7 lead to discharge flue 3, remove flue dust by spray filtering., be downward through at the water of trickle mesh when the passage 3 at flue dust, can remove dust in the cigarette by washing, simultaneously with filtered flue gas discharged to flue.

Claims
