Detailed Description

Need the fertilizer drying-machine to dry the fertilizer granule after the fertilizer granulation is accomplished, this application provides a fertilizer production exhaust chimney to purify the gas that the fertilizer stoving in-process discharged. The organic fertilizer dryer comprises a chicken manure dryer, a cow manure dryer, a horse manure dryer, a pig manure dryer, a duck manure dryer, a goose manure dryer and the like. The finished product of the organic fertilizer dryer is fine in particle, and the dried product can be used as a culture medium for planting edible mushroom agaricus bisporus and can also be sold as feed for breeding turtles, fish, snails, chickens, ducks and the like. The organic fertilizer dryer can directly dry the livestock manure with the water content of 70-80% to 13% of safe storage water content at one time, and the whole process is carried out in a closed system, so that the pollution to the environment in the drying process is reduced. The equipment mainly comprises a heat source, a feeding machine, a rotary drum, a discharging machine, a material crushing device, an induced draft fan, a discharger and a power distribution cabinet; after the dehydrated wet materials are added into a dryer, the materials are uniformly dispersed in the dryer and fully contacted with hot air under the stirring of a shoveling plate device uniformly distributed in a roller, so that the drying heat transfer and mass transfer are accelerated. In the drying process, the material is discharged to the star-shaped discharge valve at the other section of the dryer to form a finished product under the action of the shovelling plate with the inclination and the hot gas.

Can produce a large amount of gases when using the fertilizer drying-machine, contain a large amount of dusts and the material of atmospheric pollution in the gas, so this application for purify the gas that fertilizer stoving in-process discharged, has especially proposed a direct vent chimney, and is exemplary, as shown in figure 1 for the structure schematic diagram of direct vent chimney.

The direct-discharge chimney comprises a barrel body 1 and a spraying washing tower. The barrel 1 is of an upper inverted funnel type lower cylinder structure, and an air inlet, a manhole 11, a sewage draining outlet and a water inlet are formed in the side wall of the barrel 1.

The air inlet 8 is in order to receive the fertilizer stoving in-process and the production in-process produced gas, and gas comprises two parts, and the gas that the back main treatment dried fertilizer produced gets into in the chimney, because fertilizer finished product granule is dried by the heat of the gas that the fuel burning produced, can produce a large amount of gases when the fuel burning, in order to improve the environment of burning, just must discharge the gas that produces after the burning, just can guarantee going on smoothly of stoving work.

The water inlet sets up in the position that is close to the chimney export, the water inlet is used for installing second pipeline 5, the setting of second pipeline 5 is in order to make deodorant liquid cyclic utilization, when deodorant layer 9's liquid level surpassed the position of drain, will flow into first pipeline 4 along with the discharge port, enter into the spray washing tower, through the processing of spray washing tower, the recycling enters into second pipeline 5 again, the end of second pipeline 5 is provided with shower nozzle 10, spray the filter layer with deodorant, get into deodorant layer 9 again, the cost has been practiced thrift in the setting like this.

The bottom of the barrel body 1 is provided with a deodorization layer 9, the height of the whole barrel body is one third of that of the deodorization layer 9, and the height of the air inlet hole is higher than the upper surface layer of the deodorization layer 9, so that the air inlet hole is favorable for smooth entering of air.

The deodorizing layer 9 includes a deodorizing liquid and water, which are added for the purpose of preliminary purification of the entering gas, and both have an adsorbing action to adsorb some dust and harmful gases.

The spray washing tower comprises a sedimentation tank 2 and a purification tank 3, wherein the sedimentation tank 2 is communicated with the inner cavity of the barrel body 1 through a first pipeline 4, the purification tank 3 is communicated with the inner cavity of the barrel body 1 through a second pipeline 5, a drain outlet at one end of the first pipeline 4 is arranged on the side wall of the barrel body 1, and the other end of the first pipeline is arranged on the side wall of the sedimentation tank 2 and is respectively communicated with the inner cavity of the barrel body 1 and the inner cavity of the sedimentation tank 2.

The water inlet of one end of the second pipeline 5 is arranged on the side wall of the barrel 1, and the other end of the second pipeline is arranged on the side wall of the purifying tank 3 and is respectively communicated with the inner cavity of the barrel 1 and the inner cavity of the purifying tank 3.

The drain of first pipeline 4 is close to the upper surface setting of deodorant layer 9, and the water inlet of second pipeline 5 is close to the chimney export setting.

The sedimentation basin 2 can use some chemical decomposers to treat the deodorization liquid after receiving the deodorization liquid conveyed by the first pipeline 4, and finally, the substances precipitated in the sedimentation basin 2 are manually cleaned, and the rest liquid continuously flows to the purification basin 3 for the next link.

The one end that second pipeline 5 stretched into 1 inner chamber of barrel is provided with shower nozzle 10, shower nozzle 10 is a plurality of, evenly distributed is on the pipeline, be used for spraying deodorant liquid to the filter layer, continue to carry out secondary treatment to the gas of primary treatment, the liquid and the gas that spray contact the back, can wrap up some dust of big granule, make the dust in the gas can not discharged out, but circulate and subside pool 2, through chemical treatment, finally by decomposing the back manual cleaning and falling, atmospheric pollution has been reduced.

A filter layer is arranged in the cylinder body 1. The filter layer is located the transfer of shower nozzle 10, and the filter layer includes first filter layer 6 and second filter layer 7, and second filter layer 7 is close to shower nozzle 10 sets up, and first filter layer 6 is close to the inlet port setting, and first filter layer 6 is connected with the laminating of second filter layer 7, and first filter layer 6 is stainless steel plain weave filter screen frame, 7 twill stainless steel filter screen frames of second filter layer. The mesh diameter of the first filter layer 6 is larger than that of the second filter layer 7, and is set for the purpose of classifying and filtering dust and adsorbing harmful gas.

Stainless steel plain weave filter screen frame has set gradually first sponge layer 61, activated carbon layer 62 and second sponge layer 63 from the top down along 1 axis direction of barrel, and the purpose that sets up like this is to carrying out secondary deodorization and dust removal to gas, and gas is attached to through filtration, the activated carbon of first sponge layer 61 and second sponge layer 63, reaches emission standard and is superior to national emission standard.

Optionally, the ratio of the height of the first sponge layer 61 to the height of the second sponge layer 63 is 1:1.5, and the thickness of the first sponge layer 61 is smaller than that of the second sponge layer 63, so that gas is better filtered when entering the net rack and is better discharged when being discharged.

Optionally, the sponge that first sponge layer 61 and second sponge layer 63 were placed is the low density sponge, and density is the important index of material, and sponge density is high, explains that the space inside is little, so choose for use the low density sponge because the sponge space of low density is big, does benefit to the more smooth and easy discharge of gas after the processing.
