Technical Field
The utility model relates to a sludge drying equipment, especially a sludge drying equipment's tail gas processing apparatus.
Background
Sludge waste is disposed of in many ways, the main ways are incineration and composting, but both incineration and composting require waste with low water content, and therefore sludge waste needs to be dried. At present, the main way of waste drying is to place the waste in a space, heat and dry the waste to a set value, and then take the waste out. Waste material can produce tail gas when the heating, just directly discharges sludge drying equipment through simply filtering back to tail gas, still contains a lot of pollutants in the exhaust tail gas, and the whole filter effect of tail gas is not very ideal. Therefore, the prior art has the problem that the tail gas filtering effect is not ideal.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sludge drying equipment's tail gas processing apparatus. The utility model has the characteristics of can effectively improve tail gas filter effect.
The technical scheme of the utility model: a tail gas treatment device of sludge drying equipment comprises a water containing base, wherein two tail gas filters which are arranged side by side are arranged on the water containing base, and an air exchanger is arranged between the two tail gas filters; the tail gas filter comprises a shell, two layers of external filter paper nets which are distributed side by side are arranged in the shell, an internal filter paper net is arranged between the two layers of external filter paper nets, and the height of the internal filter paper net is lower than that of the external filter paper nets; and a water spraying pipe is arranged above the internal filter paper net, a water spraying hole is formed in the upper surface of the water spraying pipe, and a water retaining piece is arranged above the water spraying hole.
In the tail gas treatment device of the sludge drying equipment, the water blocking piece comprises two water blocking plates which are vertically distributed, and an included angle between each water blocking plate and the external filtering paper net is 45 degrees.
In the tail gas treatment device of the sludge drying equipment, the upper cover is arranged above the shell.
In the tail gas treatment device of the sludge drying equipment, the bottom of the shell is also provided with the cushion block.
In the tail gas treatment device of the sludge drying equipment, a drain pipe is arranged on one side of the water containing base.
In the tail gas treatment device of the sludge drying equipment, the wind gathering bin is arranged between the tail gas filter and the air exchanger.
Compared with the prior art, the utility model has the advantages that the two tail gas filters which are distributed side by side are arranged on the water containing base for double filtration treatment of tail gas, thereby effectively improving the filtering effect of the tail gas; meanwhile, the tail gas filter consists of three layers of honeycomb-shaped filter paper with different heights, so that the contact filtering area and the filtering time of tail gas are increased, and the filtering effect can be greatly improved; through set up the spray pipe that the hole for water spraying upturned and complex manger plate spare with it in the top of filtering the paper net in inside, realize a spray pipe just can spray three-layer filter paper simultaneously, simple structure, convenient operation sprays the effect also very ideal moreover. And simultaneously, the utility model discloses still install air exchanger between two tail gas filters, realize cold and hot air's quick exchange, reduce the temperature of tail gas and condense into water, can effectual improvement filtration efficiency on the one hand, on the other hand still is favorable to improving the filter effect. The utility model discloses a mutually supporting of two tail gas filters and air interchanger realizes triple filtration, very big improvement the filtration purification effect of tail gas. To sum up, the utility model has the characteristics of can effectively improve tail gas filter effect.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A tail gas treatment device of sludge drying equipment is shown in figures 1 to 5 and comprises a water containing base 1, two tail gas filters 2 which are arranged side by side are arranged on the water containing base 1, and an air exchanger 3 is arranged between the two tail gas filters 2; the tail gas filter 2 comprises a shell 201, two layers of external filter paper nets 202 distributed side by side are arranged in the shell 201, an internal filter paper net 203 is arranged between the two layers of external filter paper nets 202, and the height of the internal filter paper net 203 is lower than that of the external filter paper nets 202; a water spraying pipe 204 is arranged above the inner filtering paper net 203, the upper surface of the water spraying pipe 204 is provided with a water spraying hole 205, and a water blocking piece 206 is arranged above the water spraying hole 205.
