technical field

The utility model relates to the technical field of sewage treatment, in particular to a novel IC anaerobic reactor.

Background technique

IC (internal circulation, internal circulation) anaerobic reactor is an anaerobic reactor used to treat sewage. Wastewater flows from bottom to top in the reactor, pollutants are adsorbed and degraded by bacteria, and purified water is recovered from the reaction Outflow from the upper part of the device. IC anaerobic reactor has the following characteristics: 1) high volume load, short hydraulic retention time; 2) strong resistance to load impact; 3) avoid solid deposition; 4) low investment and small footprint; Energy consumption; 6) Low operating costs; 7) Can reduce fouling to a certain extent; 8) Stable effluent quality, etc. However, the scale and corrosion problems of the IC anaerobic reactor are difficult to solve at present. Since there is a certain height difference between the outlet of the IC anaerobic reactor and the advection section, steam will be formed at the lower elbow of the pipeline. corrosion and fouling.

Compared with the prior art, the utility model has at least the following advantages:

Through the above-mentioned technical scheme of the utility model, the water outlet structure of the existing IC anaerobic reactor is improved, the bottom bend of the original vertical water outlet pipe is removed, and a buffer tank is detachably installed at the bottom of the water outlet pipe. The buffer tank is placed in a horizontal direction, and an exhaust pipe is arranged on the upper part of the buffer tank; when the water flows down, it directly impacts the liquid in the buffer tank, thereby minimizing cavitation, and the gas generated during the downward flow of water flows along the exhaust pipe. Discharge can balance the gas pressure inside and outside the buffer tank, and will not cause severe corrosion of the buffer tank and water outlet due to cavitation pressure; because the buffer tank is detachable and installed, it is convenient to replace the buffer tank or clean the outlet pipe after long-term use, which is convenient for processing Installation, the utility model has the advantages of simple structure, low manufacturing cost and good corrosion resistance.

Description of drawings

Fig. 1 is a schematic structural view of a novel IC anaerobic reactor provided by the embodiment of the present invention.

Detailed ways

The technical solution in the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model. Apparently, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, it is a kind of novel IC anaerobic reactor that the utility model embodiment proposes, comprises reactor tank body 1, and the outer side of reactor tank body 1 is vertically provided with a water outlet pipe 2, and the outlet pipe 2 The upper end communicates with the upper side wall of the reactor tank 1, a buffer tank 3 is placed horizontally at the lower end of the outlet pipe 2, and an exhaust pipe 4 is arranged above the buffer tank 3, and the upper end of the exhaust pipe 4 is a curved outward exhaust pipe. Port 41, the exhaust pipe 4 is arranged parallel to the water outlet pipe 2; the buffer tank 3 is detachably installed at the bottom of the water outlet pipe 2, and a water outlet is opened on the buffer tank 3 and on the side of the tank body opposite to the reactor tank 1 5. The water outlet 5 is arranged along the horizontal direction.

Further, the water outlet 5 is arranged at the upper position of the buffer tank 3. Since the water outlet 5 is located at the upper position of the buffer tank, a certain amount of liquid is always stored in the buffer tank 3, and the water flow poured down from the outlet pipe 2 directly Impact the liquid in the buffer tank 3 instead of the buffer tank body, so the cavitation inside the buffer tank 3 can be effectively reduced.

Preferably, the water outlet 5 is designed in the shape of a flange interface, which is convenient for connection with an external structure.
