Abstract

The utility model discloses a totally-enclosed sludge drying and burning device with simplified structure, convenient use and high working efficiency. The totally-enclosed sludge drying and burning device comprises the structure components of a hot-blast stove, a drying machine, a cyclone dust collector, a plasma purifying device, a spraying tower, a hot air sending machine and a humidity-discharging fan. The sludge is dried in the drying machine, the hot air sending machine provides heat energy, the heat energy is generated by the hot-blast stove, sludge after dry processing is sent into thehot-blast stove for burning, the cyclone dust collector and the plasma purifying device have the function of removing dust and purifying gas, steam generated from drying is discharged from the spraying tower through dust removing and purifying, the device is a totally-enclosed structure and aims at fully circulating and utilizing heat energy and preventing unprocessed steam and dust from directlydischarging to atmosphere.

Description

Totally-enclosed drying sludge and incinerator

Technical field

The utility model relates to the mechanical means field, relates in particular to a kind of totally-enclosed drying sludge and incinerator.

Background technology

The direct burning of traditional sludge is that high humidity mud is directly burned in incinerator under the situation of auxiliary fuel as thermal source, because the water content of mud is big, calorific value is low, have only under the situation of adding auxiliary fuel (coal, heavy oil, diesel oil etc.), mud could burn, expend a large amount of energy, because sludge moisture content is big, tail gas amount after the burning is also bigger, follow-up vent gas treatment needs huge equipment, operation control difficulty is big, the corresponding device processes amounts such as follow-up spray column, deentrainment tower that cause increase greatly, and facility investment and systematic running cost are improved greatly.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of designs simplification, the totally-enclosed drying sludge and the incinerator of easy to use and high efficiency.

In order to reduce the sludge treatment working cost and to improve sludge incineration efficient, transform the direct burning of mud as mud and burn after drying, the drying and incinerating purpose of mud is the permineralization of efficient, safe realization mud.The purpose that adopts sludge drying process in the burning process front is to realize the minimizing of mud, the expense of saving follow-up incineration disposal.Moisture a large amount of in the mud are removed at drying stage, and follow-up incinerator will reduce than the volume in direct when burning, and exhaust treatment system is when equipment volume reduces, because the minimizing of water vapour content, intractability can reduce and efficient can increase.After sludge drying and incinerating carries out drying treatment to the moisture in the mud, burn and produce heat energy power-generating etc.Though one-time investment is high slightly, but because it has the not replaceable advantage of other technology, especially on the subduing of sludge quantity, sanitisation, on the final outlet, dispose on the floor space, the incomparable advantage of other technologies is all arranged, be the terms of settlement of the final outlet of a kind of mud, aspect the ultimate disposal of mud broad application prospect will be being arranged.

Totally-enclosed drying sludge and incinerator that the utility model provides comprise following structure unit: hotblast stove, drying machine, tornado dust collector, plasma purifier, spray column, hot blast fan and wet-emitting blower.Mud carries out drying treatment in drying machine, provide heat energy by the hot blast fan, the source of its heat energy is that hotblast stove produces, the intact mud of drying treatment enters in the hotblast stove and burns, tornado dust collector and plasma purifier play the function of dedusting and gas sweetening, the dry steam that is produced is discharged by spray column by dedusting and purification, and this device is a full-closed structure, and its purpose is sufficient recycle heat energy and can allow the steam and the dust that do not deal with directly be discharged in the atmosphere.

Described hotblast stove and drying machine high-temperature flue gas pipe connection, the hot blast fan designs on hotblast stove;

Described wet-emitting blower design is by spray column, and spray column is connected with plasma purifier, tornado dust collector flue successively.

Owing to adopt above-mentioned technical scheme, the utlity model has the advantage of designs simplification, simple to operate, easy to use and high efficiency.

Embodiment

As depicted in figs. 1 and 2, the totally-enclosed drying sludge and the incinerator that provide of the utility model comprises hotblast stove 1, drying machine 2, tornado dust collector 3, plasma purifier 4, spray column 5, hot blast fan 6 and wet-emitting blower 7.Mud carries out drying treatment for 2 li at drying machine, provide heat energy by hot blast fan 6, the source of its heat energy is that hotblast stove 1 produces, the intact mud of drying treatment enters in the hotblast stove 1 and burns, tornado dust collector 3 and plasma purifier 4 play the function of dedusting and gas sweetening, the dry steam that is produced is discharged by spray column 5 by dedusting and purification, this device is a full-closed structure, and its purpose is sufficient recycle heat energy and can allow the steam and the dust that do not deal with directly be discharged in the atmosphere.

Described hotblast stove 1 and drying machine 2 high-temperature flue gas pipe connection, 6 designs of hot blast fan are on hotblast stove 1;

Described wet-emitting blower 3 designs are other at spray column 5, and spray column 5 is connected with plasma purifier 4, tornado dust collector 3 flue successively.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
