Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

The utility model provides a lime feed bin tail gas processing apparatus, see figure 1, include:

a tail gas pipe 1;

the device comprises a lime preparation barrel 2, a tail gas pipe 1 is arranged on the side surface of the lime preparation barrel 2, and one end of the tail gas pipe 1 is connected with a lime bin;

the branch pipe 3 is arranged in the lime preparation barrel and is connected with the other end of the tail gas pipe 1, a plurality of openings are formed in the branch pipe 3, and the openings face the bottom of the lime preparation barrel 2;

a feed inlet of the preparation barrel and a valve 4, wherein the feed inlet of the preparation barrel and the valve 4 are arranged above the lime preparation barrel 2.

When lime enters the lime silo body 12 from the lime feed inlet 13 of the lime silo body 12, most of the lime descends to the bottom of the lime silo body 12 under the action of gravity. Influenced by the high pressure simultaneously, lime feed bin body 12 internal pressure grow, and partial raise dust passes through branch pipe 3 that tail gas pipe 1 got into lime and prepares 2 interior, and the trompil that makes progress through branch pipe 3 down contacts with lime and prepares 2 interior waters. Lime is desorbed by water and becomes lime emulsion, thereby realizing the recovery of tail gas.

Preferably, the tail gas pipe 1 is provided with a gas-phase one-way valve 5 and a liquid-phase one-way valve 6, and the gas-phase one-way valve 5 and the liquid-phase one-way valve 6 are used for preventing gas and liquid in the lime preparation barrel from entering the lime bin body 12.

When the pressure in the lime bin body 12 is increased, the gas-phase one-way valve 5 and the liquid-phase one-way valve 6 are opened in one way, and the raised dust enters the lime preparation barrel 2 through the tail gas pipe 1. And when the pressure in the lime preparation barrel 2 is too high, the gas-phase one-way valve 5 and the liquid-phase one-way valve 6 are closed, so that the raised dust and the liquid in the lime preparation barrel 2 can not flow back to the lime bin body 12.

Preferably, the lime preparation tub bottom is further provided with a branch pipe support 7 for supporting the branch pipe 3.

In order to ensure that the tail gas is fully fused with the water at the bottom of the lime preparation barrel, a plurality of openings are required to be formed in the branch pipe 3, so that the length of the branch pipe 3 is also longer, and therefore, a branch pipe support 7 for supporting the branch pipe 3 is required to be arranged at the bottom of the lime preparation barrel.

Preferably, the lime preparation barrel 2 is further provided with a liquid level meter 8 at the side for indicating the liquid level in the lime preparation barrel 2.

Liquid level control in the lime preparation bucket is at well liquid level through level gauge 8 to guarantee that the raise dust that gets into can carry out abundant reaction.

Preferably, a pressure balancing hole 9 is further formed above the lime preparation barrel 2.

Since the pressure in the lime preparing tub 2 is large, a pressure balancing hole 9 is provided to balance the air pressure.

Preferably, the pressure balance block is sleeved with the dust isolation device 10.

As the pressure in the lime preparation barrel 2 is large, part of dust rushes out of the liquid level, and the dust needs to be isolated in the barrel while the pressure balance is kept, the dust isolating device 10 is arranged. The dust isolation device 10 can be a cloth bag, which can not only keep pressure balance, but also intercept dust.

Preferably, a stirrer 11 is further provided in the lime preparation tub 2.

The stirrer 11 is used for mixing lime and water and stirring them to allow them to react sufficiently.

Preferably, the diameter of the tail gas pipe 1 is more than 100mm and less than 150mm, and the diameter of the bronchus is not less than 40mm and not more than 63 mm.

This arrangement prevents the tailpipe 1 and branch 3 from becoming clogged.

Preferably, the dust separating device 10 has a separating aperture of 5 μm.

The isolating caliber is 5 mu m, so that lime dust can be effectively trapped and the air pressure balance can be kept.

Rely on foretell lime feed bin tail gas processing apparatus, the utility model also provides a lime feed bin, including lime feed bin body 12, lime feed inlet 13 and lime discharge gate 14, lime discharge gate 14 passes through exhaust pipe 1 with the arbitrary lime feed bin tail gas processing apparatus of the aforesaid and is connected.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
