Description

A kind of environmentally-friendly sludge desiccation apparatus
Technical field
The invention belongs to sludge disposal technology, more particularly, to a kind of environmentally-friendly sludge desiccation apparatus.
Background technology
Treatment of Sludge principle is minimizing, stabilisation, harmless resource utilization.The main method of sludge treatment is mainly soil Using, agricultural sludge, landfill, recovery energy and comprehensive utilization.Either any method, sludge drying are all important One step, volume and quality are greatly reduced after sludge drying, and bacterium and pathogen are effectively removed, while nutritional ingredient and calorific value Be maintained, can further fill, compost, burning and land use.
Sludge heat drying can be divided into direct heat drying, indirect thermal drying technique according to thermal medium and the sludge way of contact.Between Connect the application that heat drying is heat transfer drying technique.The heating and drying machine wall of thermal medium makes the sludge in desiccation machine be heated, moisture Evaporation.Thermal medium does not contact directly with sludge in drying process, thus heat transfer efficiency than it is relatively low, moisture evaporation speed is low.And one As the moisture percentage in sewage sludge that dispatches from the factory be substantially 80-85%, cannot meet the needs of actual using indirectly drying.Direct heat drying is The application of thermal convection current drying technique.Enter after thermal medium heating in desiccation machine and mixing is directly contacted with sludge, sludge heating, moisture Evaporation.Thermal medium is directly contacted and is contaminated with sludge in the process, and the exhaust steam and waste water of discharge need to be through innoxious places Discharged after reason.The technology rate of heat transfer and moisture evaporation speed are higher.But at present still based on introduction of foreign technology and equipment, because This selects rational drying process, safe and stable, inexpensive and handle sludge on a large scale, is that current sludge drying is badly in need of solution Certainly the problem of.
The content of the invention
It is an object of the invention to provide a kind of environmentally-friendly sludge desiccation apparatus, it is with drying efficiency is high, energy saving and ring The characteristics of guarantor, to solve the above problem present in mud drying process in the prior art.
For this purpose, the present invention uses following technical scheme:
A kind of environmentally-friendly sludge desiccation apparatus, it includes closed garbage raw material workshop, air-introduced machine, heat exchanger, sludge baking Dry cylinder and pyrolysis gasification furnace, wherein, low temperature foul smell leading-in end, high temperature foul smell outlet side and high temperature tail are provided with the heat exchanger Gas upstream end, the garbage raw material workshop introduce pipeline by foul smell and are connected with low temperature foul smell leading-in end, and the air-introduced machine is set Introduced in the foul smell on pipeline, the high-temperature tail gas of the pyrolysis gasification furnace is connected by exhaust pipe and the high-temperature tail gas upstream end The heat source as heat exchanger is connect, the sludge drying being connected with the pyrolysis gasification furnace is connected with the high temperature foul smell outlet side Pipeline, the sludge Drying for being contained with sludge to be dried is set on the sludge drying pipeline.
Especially, tail gas outlet side is additionally provided with the heat exchanger, vent gas treatment is connected with the tail gas outlet side Pipeline, the vent gas treatment pipeline will introduce tail gas treatment device by the high-temperature tail gas of heat exchanger and handled.
Especially, the pyrolysis gasification furnace uses bilingual stove, and the exhaust pipe enters the dual firing chamber of the bilingual stove.
Especially, the foul smell temperature in the sludge drying pipeline is 150 DEG C~200 DEG C.
Especially, the garbage raw material be house refuse, any or both mixture of river sludge.
Beneficial effects of the present invention are that the environmentally-friendly sludge desiccation apparatus can realize sludge compared with prior art Desiccation, removes the foul smell in rubbish workshop, and high efficiency utilizes the fume afterheat that pyrolysis oven produces, external energy is not required in drying process The input of amount, will not produce subsequent contamination.Not only technique is simple, it is easy to accomplish;And energy saving, environmental protection, sludge drying efficiency It is high.

Embodiment
Further illustrate technical scheme below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, the structure that Fig. 1 is the environmentally-friendly sludge desiccation apparatus that the specific embodiment of the invention provides is shown It is intended to.
In the present embodiment, a kind of environmentally-friendly sludge desiccation apparatus includes garbage raw material workshop 1, air-introduced machine 2, heat exchanger 3, dirt Mud Drying 4 and the bilingual stove 5 of rubbish, 1 memory of garbage raw material workshop put pending house refuse, and garbage raw material car Between 1 sealed set be enclosed within the foul smell for producing house refuse in garbage raw material workshop 1, to prevent foul smell from leaking, pollution week Collarette border.
Low temperature foul smell leading-in end 30, high temperature foul smell outlet side 31, high-temperature tail gas upstream end 32 are provided with the heat exchanger 3 With tail gas outlet side 33, the garbage raw material workshop 1 introduces pipeline 6 by foul smell and is connected with low temperature foul smell leading-in end 30, described Air-introduced machine 2 is arranged at the foul smell and introduces on pipeline 6, and the high-temperature tail gas in the dual firing chamber of the bilingual stove 5 of rubbish passes through exhaust Pipe 7 and the high-temperature tail gas upstream end 32 are connected to the heat source of heat exchanger 3, be connected with the high temperature foul smell outlet side 31 with The sludge drying pipeline 8 that the bilingual stove 5 of rubbish is connected, sets on the sludge drying pipeline 8 and is contained with sludge to be dried Sludge Drying 4, be connected with vent gas treatment pipeline 9 on the tail gas outlet side 33, the vent gas treatment pipeline 9 will be by changing High-temperature tail gas in hot device 3 introduces tail gas treatment device 10 and is handled.
During work, the foul smell in garbage raw material workshop 1, the high-temperature flue gas that the bilingual stove 5 of rubbish is produced are collected by air-introduced machine 2 Heat exchanger 3 is sent to, foul smell and tail gas are not directly contacted with, and foul smell is heated to 150 DEG C~200 DEG C, after heating using heat exchanger 3 Foul smell be sent to sludge Drying 4 in it sludge carry out desiccation.Desiccation mode is directly heats, and gas is direct after desiccation Burn into bilingual stove, do not produce secondary pollution.The tail gas produced in drying process is burned again into bilingual stove, without secondary Pollution.
Above example is to elaborate the basic principle and characteristic of the present invention, and the present invention limits from above-mentioned example, Without departing from the spirit and scope, the present invention also has various changes, these changes and modifications are both fallen within In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
