Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge conditioning, and in particular to a sludge conditioning device. BACKGROUND

[0002] In the technical field of sewage conditioning, improving the dewatering performance of sludge is a key step to ensure the effectiveness and efficiency of sewage treatment. By adding coagulants and flocculants to the sewage, suspended fine particles can be agglomerated into larger clumps, which are easier to separate from water, thereby significantly reducing filtration resistance and improving dewatering efficiency. This process not only helps to reduce the cost of subsequent treatment, but also effectively reduces environmental pollution, which is of great significance to environmental protection.

[0003] The existing sludge conditioning equipment usually includes a conditioning tank or a sludge storage chamber for storing sludge. In the automated operation process, coagulants and flocculants are precisely added to the sludge through a connected pipeline system to assist the dewatering process. This design aims to minimize the need for human resources and achieve higher automation levels, in line with the modern industry's trend of pursuing efficiency and low consumption. The automated control system can monitor the addition process of the reagents to ensure that they are dispensed according to the preset ratio, further simplifying the operation process and improving work efficiency.

[0004] Although the above-mentioned sludge conditioning device has made progress in automation, there are still some deficiencies in actual application. In particular, in the reagent preparation stage, the existing equipment does not provide a separate mixing link before the coagulant and flocculant are added to the conditioning tank, which makes the reagents unable to achieve the best chemical property state, affecting their reaction efficiency with the sludge. In addition, due to the lack of effective metering control means, the amount of reagents added is difficult to accurately adjust according to the actual situation, resulting in problems such as overuse or uneven dispensing, which not only wastes resources, but also may affect the final dewatering quality due to poor conditioning effect. Therefore, it is necessary to develop a new type of sludge conditioning device that can ensure uniform mixing of reagents before they are added and has fine metering function to improve the effectiveness and economy of sludge conditioning.

[0047] In the following, certain example embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be considered exemplary in nature rather than limiting.

[0048] Reference Figure 1As shown, the sludge conditioning device in the embodiments of the present application can include: a conditioning reaction tank 1 for storing sludge to be conditioned; a medicament dissolving tank 2 for storing medicament having the function of conditioning sludge; a first stirring mechanism 4 arranged in the conditioning reaction tank 1 for stirring the sludge, the first stirring mechanism 4 being capable of adjusting the stirring rate in the conditioning reaction tank 1; a second stirring mechanism 5 arranged in the medicament dissolving tank 2 for stirring the medicament, the second stirring mechanism 5 being capable of adjusting the stirring rate in the medicament dissolving tank 2; a medicament feeding mechanism, the medicament dissolving tank being in communication with the conditioning reaction tank through the medicament feeding mechanism; and a water content monitoring component 6 arranged in the conditioning reaction tank 1 for monitoring the water content of the sludge in the conditioning reaction tank 1; the water content monitoring component 6 is in communication connection with the medicament feeding mechanism, the water content monitoring component 6 being capable of sending a first signal to the medicament feeding mechanism, the first signal being used to represent the water content of the sludge in the conditioning reaction tank 1.

[0049] The medicament feeding mechanism can control the amount of medicament discharged into the conditioning reaction tank 1 through the first signal.

[0050] Specifically, in the technical scheme adopted in the present application, in some embodiments, the conditioning reaction tank 1 can be arranged adjacent to the medicament dissolving tank 2, that is, the medicament dissolving tank 2 is arranged on one side of the conditioning reaction tank 1 to facilitate communication through the medicament feeding mechanism. In the present application, the first stirring mechanism 4, the second stirring mechanism 5 and the medicament feeding mechanism can be controlled by a programmable logic controller (PLC) according to the amount of sludge and / or the amount of medicament. In the present application, the first stirring mechanism 4 can adjust the stirring rate in the conditioning reaction tank 1 through the programmable logic controller; the second stirring mechanism 5 can also adjust the stirring rate in the medicament dissolving tank 2 through the programmable logic controller; and the medicament feeding mechanism can control the amount of medicament added to the conditioning reaction tank 1 according to the water content of the sludge, so that the sludge conditioning device can adjust the stirring rate and the amount of medicament according to the actual situation, so that the sludge can be quickly dewatered in the conditioning reaction tank 1, and the dewatered sludge can be obtained by adding an appropriate amount of medicament, so as to improve the dewatering efficiency and effect of the sludge. In the present embodiment, the water content monitoring component 6 for monitoring the water content of the sludge in the conditioning reaction tank 1 is arranged in the conditioning reaction tank 1, and the water content monitoring component 6 is in communication connection with the medicament feeding mechanism, so that the water content data of the sludge measured by the water content monitoring component 6 is transmitted to the programmable logic controller, converted into a first signal by the programmable logic controller, and then sent to the medicament feeding mechanism, so that the medicament feeding mechanism can adjust the amount of medicament added to the conditioning reaction tank 1 according to the real-time monitoring of the water content of the sludge.

[0051] In the embodiments of the application, the water content monitoring component 6 can be a sludge concentration meter, which reflects the water content of the sludge by detecting the solid content in the sludge. Common ones include optical, ultrasonic, capacitive, etc. The optical sludge concentration meter utilizes the scattering and absorption principle of light. When light passes through the sludge, the intensity of the transmitted light changes due to the scattering and absorption of light by the solid particles in the sludge, thereby measuring the concentration of the sludge; the ultrasonic type is measured according to the relationship between the propagation speed and attenuation degree of ultrasonic waves in the sludge and the sludge concentration; the capacitive sludge concentration meter is based on the principle of capacitance. The dielectric constant of the sludge as a dielectric medium is related to the water content, and the sludge concentration is determined by measuring the change of the capacitance. Or, the electromagnetic pulse probe is a sensor probe based on the frequency domain reflection method (FDR). It utilizes the principle of electromagnetic pulse, detects the dielectric constant of the sludge according to the frequency shift of electromagnetic waves in the sludge, and obtains the water content of the sludge. When a high-frequency electric field is applied between the two sensitive electrodes of the sensor probe, the coupling strength of the electric field between the electrodes is significantly related to the water content of the sludge, and the water content is indirectly measured by measuring the change of the equivalent capacitance. Since the sludge concentration meter and the electromagnetic pulse probe are prior art, they will not be described here.
