The sludge conditioning and modifying system comprises a primary modification tank used for mixing conditioning agents with sludge and a secondary modification tank used for reacting the conditioning agents with the sludge, wherein a discharging hole of the primary modification tank is communicated with a feeding hole of the secondary modification tank; a first stirring device is arranged in the primary modification tank; a second stirring device is arranged in the secondary modification tank; the rotation speed of the first stirring device is higher than that of the second stirring device. By virtue of the adoption of the graded conditioning and modifying system, the sludge can be fully reacted with the conditioning agents; the dosing quantity of the conditioning agents can be reduced; meanwhile, different conditioning grades are prepared for different sludge characteristics; the optimal economic benefit and environmental protection benefit of conditioning and modification of the sludge can be achieved.
Description
Technical field
The invention belongs to field of sludge treatment, be specifically related to a kind of sludge conditioning reforming system.
Background technology
Due to the unstable of the complicacy of sludge quality, polytropy and sludge handling process, the selection carrying out stirring intensity and churning time according to the character of mud is needed when carrying out nursing one's health modification, simultaneously for guaranteeing economy and the feature of environmental protection of nursing one's health modifying process, need the optimum proportion determining adding of agent, prevent from blindly adding a large amount of improved chemical.
When original employing diaphragm filter press carries out deep dehydration, adopt circle or the Fang Xing Gang Quan structure sludge conditioning pond of comparatively large vol, the volume of usual circle or square conditioner is at 100-300m
3, adopt the conditioner of this kind of mode to there is following shortcoming: to add pharmaceutical quantities in (1) short period of time large, the image that medicament sinks to the bottom easily occur; (2) because pond body bulk is comparatively large, higher to the requirement of stirring, adopt conventional alr mode to stir; (3) nurse one's health structure formation single, once sludge shale changes, can only adopt the increase added amount of chemical of extensive style, economic benefit is poor.
Summary of the invention
The object of this invention is to provide the sludge conditioning reforming system that a kind of reaction efficiency is high, can guarantee lasting feed.
For achieving the above object, the invention provides following technical scheme: a kind of sludge conditioning reforming system, comprise the one-level modified tank for mixing amendment and mud, and supplying amendment and mud to carry out the secondary modified tank reacted, the discharge port of one-level modified tank is communicated to the opening for feed of secondary modified tank; Be provided with the first whipping appts in described one-level modified tank, in secondary modified tank, be provided with the second whipping appts, and the rotating speed of the first whipping appts is greater than the rotating speed of the second whipping appts.
Technique effect of the present invention is: adopt classification conditioning reforming system, the abundant reaction of mud and amendment can be realized, reduce the dosage of amendment, simultaneously for different conditioning progression can be equipped with during different shale, realize optimization economic benefit and the environmental benefit of sludge conditioning modification.
Accompanying drawing explanation
Fig. 1 is systematic schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of sludge conditioning reforming system, comprises the one-level modified tank 10 for mixing amendment and mud, and supplies amendment and mud to carry out the secondary modified tank 20 reacted, and the discharge port of one-level modified tank 10 is communicated to the opening for feed of secondary modified tank 20; Be provided with the first whipping appts 11 in described one-level modified tank 10, in secondary modified tank 20, be provided with the second whipping appts 21, and the rotating speed of the first whipping appts 11 is greater than the rotating speed of the second whipping appts 21.With traditional stirring, mixing integral type modification pond is compared, the present invention adopts two modified tanks to enter high-speed row respectively and stirs and low speed reaction, the two can operate simultaneously, after the sludge reaction in secondary modified tank 20 completes and exports, mud after stirring in one-level modified tank 10 can enter secondary modified tank 20 immediately and react, new mud can be added again and amendment stirs in one-level modified tank 10, stirring thus can be synchronous with reaction, continuous print carries out, make the single modification cycle time of mud, lasting feed can be realized, substantially increase equipment capacity.
Further, the discharge port of secondary modified tank 20 is communicated to mud storage tank 30 through transferpump 40, and be provided with the stirring at low speed device 31 for preventing sludge settling in described mud storage tank 30, the discharge port of described mud storage tank 30 is communicated to pressure filter through charging pump.
Preferably, described one-level modified tank 10 is arranged in height orientation with secondary modified tank 20, at the bottom of the tank of one-level modified tank 10 higher than or flush in the abhiseca of secondary modified tank 20, the discharge port of described one-level modified tank 10 is positioned at tank bottom.
Further, the pipeline between described one-level modified tank 10 discharge port and secondary modified tank 20 opening for feed is provided with stopping valve 12.
Further, described one-level modified tank 10 and secondary modified tank 20 are at least provided with two groups, and secondary modified tank 20 discharge port of each group is individually communicated to mud storage tank 30 or is communicated to mud storage tank 30 after reversing valve 22 parallel connection.The present invention arranges modified tank more than two, and when wherein one group of modified tank feed, modified tanks of other groups react, and after this group modified tank feed completes, the complete modified tank of other group reactions is sustainable carries out feed, achieves continuous seepage.
Further, as preferred version of the present invention, the volume of described one-level modified tank 10 and secondary modified tank 20 is all at 8m
3-30m
3between.The present invention, by modified tank miniaturization, stirs more fully, evenly, adds pharmaceutical quantities little in the short period of time, and the image that medicament sinks to the bottom not easily occurs; Conditioning structure formation is various, when sludge shale changes, can adjust amendment in time and throw in ratio.
Principle of work of the present invention is as follows:
One-level modified tank 10: adopt metering outfit quantitatively to add certain amendment and enter one-level modified tank 10, one-level modified tank 10 adopts Large-power High-Speed mix and blend, mud in tank is made to be turbulence form, realize mud and amendment short mix even, for the carrying out of follow-up conditioning modification provides condition;
Secondary modified tank 20: secondary modified tank 20 and one-level modified tank 10 are in height distribution pattern, mud after one-level modified tank 10 processes enters secondary modified tank 20, secondary modified tank 20 adopts low power stirring at low speed pattern, mud in tank is made to be laminar flow, mud fully contacts with medicament, the reaction process of accelerate sludge and amendment.
Mud storage tank 30: after mud and amendment react and substantially completes, stir through transferpump 40 and be delivered to mud storage tank 30, mud storage tank 30 is equipped with stirring at low speed device 31, its Main Function is the subsequent reactions promoting mud and amendment, prevent modified mud to be separated the mud solid content causing precipitating with water too high simultaneously, follow-up pressure filter cannot be met and enter mud condition.
The present invention adopts classification to nurse one's health reforming system, the abundant reaction of mud and amendment can be realized, reduce the dosage of amendment, simultaneously for different conditioning progression can be equipped with during different shale, realize optimization economic benefit and the environmental benefit of sludge conditioning modification.
