The export of conditioning tank is connected with the feed pump, and the feed pump export is connected with full-automatic diaphragm plate frame filter press inlet material mouth, and full-automatic diaphragm plate frame filter press feed opening is connected with the wet feed bin of balladeur train, and the export of the wet feed bin of balladeur train is connected with scraper conveyor, and scraper conveyor discharge gate and mud low temperature mummification machine are connected, and the export of mud low temperature mummification machine is connected with the buffer storage storehouse feed inlet. The advantage is novel structure, through adopting full-automatic diaphragm plate frame filter press and mud low temperature mummification machine, can realize mud low temperature mummification, realizes the volume reduction decrement of mud, adopts closed processing simultaneously, can improve the site environment, reduces subsequent waste gas treatment investment etc. and mud treatment realizes continuous operation, has certain advantage in investment cost, running cost, the subsequent processing degree of difficulty, more economic environmental protection when saving the cost.
Description
Technical Field
The utility model belongs to the technical field of straw pulping and papermaking wastewater sludge treatment, in particular to a papermaking and pulping wastewater sludge volume reduction and decrement treatment system,
background
At present, the sludge treatment modes in China mainly comprise mechanical dehydration, landfill, high-temperature heat drying, sludge incineration, aerobic composting, fermentation, anaerobic digestion and the like. Among the existing treatment modes, a single sludge treatment mode has certain defects, wherein the defects are mainly reflected in that the sludge reduction is not obvious, the subsequent treatment is difficult, the equipment investment and the operation cost are high, the equipment loss is large, the failure rate is high, the operation is difficult to stabilize, the problem of pollution of the sludge to the environment is not fundamentally solved, and the harmlessness, the stabilization and the recycling are difficult to realize.
Disclosure of Invention
The utility model provides a papermaking and pulping wastewater sludge volume reduction and decrement treatment system, which aims to solve the problem that the pollution of sludge to the environment cannot be fundamentally solved at present.
The utility model adopts the technical scheme that the device comprises a conditioning tank, a high-pressure plunger pump, a full-automatic diaphragm plate-and-frame filter press, a carriage wet material bin, a scraper conveyor, a sludge low-temperature drier and a buffer bin, wherein the outlet of the conditioning tank is connected with a feeding pump, the outlet of the feeding pump is connected with the material inlet of the full-automatic diaphragm plate-and-frame filter press, the feed opening of the full-automatic diaphragm plate-and-frame filter press is connected with the carriage wet material bin, the outlet of the carriage wet material bin is connected with the scraper conveyor, the discharge opening of the scraper conveyor is connected with the sludge low-temperature drier, and the outlet of the sludge low-temperature drier is connected with the feed opening of the buffer bin.
The utility model has the advantages of novel structure, capability of controlling and treating the moisture of the front section of sludge generated in the straw pulping and papermaking wastewater treatment process and creating treatment conditions for the rear section, capability of realizing low-temperature sludge drying and volume reduction of the sludge by adopting a full-automatic diaphragm plate-and-frame filter press and a low-temperature sludge drying machine, capability of improving the field environment, reducing the subsequent waste gas treatment investment and the like by adopting closed treatment, capability of realizing continuous operation of sludge treatment, certain advantages in investment cost, operation cost and subsequent treatment difficulty, and more economic and environmental protection while saving the cost.

Detailed Description
Including taking care of jar 1, high-pressure plunger pump 2, full-automatic diaphragm plate and frame filter press 3, balladeur train wet material storehouse 4, scraper conveyor 5, mud low temperature mummification machine 6 and buffer storehouse 7, wherein take care of 1 export of jar and be connected with feed pump 2, the export of feed pump 2 is connected with full-automatic diaphragm plate and frame filter press feed inlet 3, 3 feed openings of full-automatic diaphragm plate and frame filter press are connected with balladeur train wet material storehouse 4, 4 exports in balladeur train wet material storehouse are connected with scraper conveyor 5, 5 discharge gates of scraper conveyor are connected with mud low temperature mummification machine 6, 6 exports in mud low temperature mummification machine are connected with buffer storehouse 7 feed inlets.
The working process is as follows:
after a flocculating agent is added to sludge, the sludge is fully mixed in a conditioning tank 1, the mixed sludge enters a full-automatic diaphragm plate and frame filter press 3 through a high-pressure plunger pump 2 for mechanical dehydration, the dehydrated sludge with the water content of 60% enters a carriage wet bin 4, the sludge in the carriage wet bin 4 enters a low-temperature sludge drier 6 through a scraper conveyor 5, the sludge low-temperature sludge drier 6 dries the sludge with the water content of 60% to the water content of 35% to realize volume reduction and reduction of the sludge, and the dried sludge enters a buffer storage bin 7.
