Abstract

The utility model discloses a biomass smoke spraying dedusting pond which comprises a cavity provided with a smoke inlet and a smoke outlet. The bottom of the cavity is provided with a water layer. A plurality of upper partition walls are erected on the bottom of the cavity. The top ends of the upper partition walls are exposed out of the water surface. The top of the cavity is provided with a spraying unit. A plurality of lower partition walls are hung on the top wall. The lower ends of the lower partition walls are arranged above the water surface. The upper partition walls and the lower partition walls are arrayed in a stagger mode at intervals. Biomass smoke passes above the water surface, the partition walls form return strokes and drop to the water pond under the action of self-load inertia generated by circuitous turning, water spray injected the spray pipe and absorbing action, and therefore the smoke is purified.

Description

Biomass flue gas spraying and dedusting pond

Technical field

The utility model relates to a kind of cleaner, specifically relates to a kind of pond that utilizes shower water to remove impurities in biomass flue gas.

Background technology

Along with the minimizing day by day of fossil and the known proved reserves of fossil energy, traditional energy is accelerating towards exhausted edge.In order actively to deal with energy crisis at hand, people have found alternative regenerative resource, and biomass energy is a kind of exceedingly beautiful energy of renewable, reusable edible.Just because of this, the exploitation of biomass fuel in recent years, recycle, produce and received unprecedented concern.The agriculture and forestry organic waste material that the raw material of biomass fuel is mainly got; by a series of deep processing, usually produce biological particles or powder, change into biomass energy after both are burnt respectively and provide alternative energy source for industry; not only solve the processing problem of agriculture and forestry organic waste material, also reduced CO ₂With pernicious gas to airborne release.

In recent years; country is successively putting into effect multinomial policy aspect protection of the environment and Renewable Energy Development; encourage to clean, develop biomass fuel efficiently, make numerous coal-burning boilers be eliminated or transform burning-used biologic mass fuel as, this several years Developing Extensions of biomass fuel boiler are rapid.And for biomass fuel boiler, former little, medium-sized fire coal boiler fume is processed the water film dust removal device adopted and is not suitable for, need a kind of novel cleaner to replace, can filter out more tiny biomass fuel flue dust, the boiler smoke discharge is complied with the national standard requirements.

The utility model content

The problem existed in order to solve prior art, the utility model provides a kind of dedusting pond of effective filtering biological matter flue dust.

In order to realize above purpose, the technical solution of the utility model is as follows: a kind of biomass flue gas spraying and dedusting pond, comprise that one has the cavity of gas approach and exhanst gas outlet, the bottom of described cavity arranges water layer and holds up some upper partition walls, and horizontal plane is exposed on the top of upper partition wall; The top of described cavity arranges the spray assembly, and roof hangs establishes some lower partition walls, and the bottom of lower partition wall is positioned on horizontal plane; Described upper partition wall and lower partition wall are staggered respectively to be arranged.

Further, the wall body in described exit connects upper cross plate, and is positioned at the upper partition wall bottom connection lower cross plate in exit.

The bottom of described cavity is equipped with slope.

One side of described cavity is extended connection one tank.

Compared with prior art, the biomass flue gas that contains flue dust passes through on pond, through partition wall, forms six strokes, under the deadweight effect of inertia of flue dust due to the S-turn generation, the water spray that adds shower catches, suction-operated falls into pond, thereby purified biomass flue gas.

The characteristics of this patent:

1, simple in structure, the flow of flue gas resistance is little;

2, flue gas is through too much backhaul, and multiple spot sprays, and efficiency of dust collection is high, can catch fine dusts;

3, shower water can be recycled, and can not cause the waste of water;

4, the last stroke of flue gas is provided with two diaphragm plates, can effectively separate the moisture carried in flue gas.

The accompanying drawing explanation

The internal structure schematic diagram that Fig. 1 is the dedusting pond.

The side view that Fig. 2 is Fig. 1.

Below, with preferred embodiment, the utility model is further specifically described by reference to the accompanying drawings.

The specific embodiment

As shown in Figure 1, the cavity that the main body in dedusting pond is interior sky, be the square arrangement general layout.The left wall 1 of cavity is offered gas approach 3, and the roof of cavity is offered exhanst gas outlet 8.There is water the bottom of cavity as the pond poultry, holds up partition wall 6 under two sides, the high water-yielding stratum of partition wall in pond.The top of cavity arranges four rows and sprays assembly 4.Three upper partition walls 5 of the roof lifting of cavity, there is an intersegmental distance on dried up plane, the bottom of upper partition wall.In order to allow flue gas be dioptric type, flow, the alternate arrangement that interlocks of upper partition wall and lower partition wall.In order to stop flue gas to carry moisture when leaving exhanst gas outlet, connect lower cross plate 11 in the bottom of last upper partition wall 7, and connect upper cross plate 9 at right wall 10.

In order to overhaul the dedusting pond and to observe the water layer water level, stretch out and build effluent trough 14 at the antetheca 15 of cavity, tank is connected with water layer.

In order to remove easily the deep impurity of the flue dust in water layer, the high-end rear wall 12 that is positioned on 13， slope, laying slope, the bottom of cavity.

The flue gas that boiler is discharged enters from dedusting pond gas approach, ash-laden gas is through the spray of spray pipe component, produce spraying, dust is by water droplet collision, interception and cohesion, with drops of water fall down to the pond, below, and flue gas is walked around partition wall on water layer, produce tortuous flowing in staggered partition space, the flue dust in flue gas relies on self gravitation to fall to water layer, in the end in stroke, separate moisture by diaphragm plate, final clean flue gas is discharged from exhanst gas outlet.

Claims

1. a biomass flue gas spraying and dedusting pond, comprise that one has the cavity of gas approach and exhanst gas outlet, it is characterized in that: the bottom of described cavity arranges water layer and holds up some upper partition walls, and horizontal plane is exposed on the top of upper partition wall; The top of described cavity arranges the spray assembly, and roof hangs establishes some lower partition walls, and the bottom of lower partition wall is positioned on horizontal plane; Described upper partition wall and lower partition wall are staggered respectively to be arranged.
