The generally application of above-mentioned rotary kiln, improves economic benefit, but gives off a large amount of pernicious gases, if directly discharge enters air, will cause very serious pollution.In the waste gas of rotary kiln discharge, oxygen content is low, and main component is the sour gas such as carbon dioxide, sulfur dioxide, nitrogen oxide.

Existing emission-control equipment, is difficult to process rotary kiln this type high temp of waste gas and the waste gas containing a large amount of sour gas.

Utility model content

The purpose of this utility model is to provide a kind of rotary kiln waste gas filter, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of rotary kiln waste gas filter, comprise air inlet, first cleaning position, cooling storehouse, second cleaning position and exhaust outlet, described air inlet is fixedly connected on the left side of the first cleaning position, described first cleaning position top is provided with humidifier, bottom is provided with sewage draining exit, described humidifier top is connected by pipeline with alkali lye pond, the right side of described first cleaning position is fixedly connected with by the right side of pipeline with cooling storehouse, the inside in described cooling storehouse is fixedly connected with cooling fin and cold water pipe, the pipeline that passes on left in described cooling storehouse is fixedly connected with the left side of the second cleaning position, the left side of described second cleaning position inner chamber is provided with electrostatic precipitator, the positive plate of described electrostatic precipitator and minus plate are separately positioned on top and the bottom of the second cleaning position, active carbon bag is provided with on the right side of the inner chamber of described second cleaning position, the inside of described active carbon bag is provided with through hole, described exhaust outlet is fixedly connected on the right side of the second cleaning position.

Preferably, described humidifier is provided with 4 to 6 groups, and is arranged in a linear successively and is arranged on the top of the first cleaning position.

Preferably, described cold water pipe S-type running through with cooling fin is connected, and described cooling fin arranges more than 5, and is parallel to each other between cooling fin.

Preferably, described through hole is linear pattern or S type, and the quantity of through hole is no less than 10.

Technique effect of the present utility model and advantage: the alkali lye atomization in alkali lye pond is sprayed into the first cleaning position by humidifier by this rotary kiln waste gas filter, the temperature of waste gas is reduced, by sulfide wherein, nitrogen oxide and bulky grain are deposited to the bottom of the first cleaning position, discharged by sewage draining exit, remaining gas enters cooling storehouse, further cooling, reduce the damage to subsequent purification equipment, after entering the second cleaning position, the fine particle of non-sedimentation is removed by electrostatic precipitator, again after the through hole of active carbon bag, last remaining harmful substance is absorbed, after harmful substance is up to standard, discharge enters air, this rotary kiln waste gas filter structure is simple, easily disassemble maintenance, and purification rapidly, what purify is thorough, energy consumption is low, play a role in energy saving.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1 air inlet, 2 first cleaning positions, 3 humidifiers, 4 sewage draining exits, 5 alkali lye ponds, 6 cooling storehouses, 7 cooling fins, 8 cold water pipes, 9 second cleaning positions, 10 electrostatic precipitator, 11 active carbon bags, 12 exhaust outlets, 13 through holes, 14 positive plates, 15 minus plates.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
