Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to a novel IC anaerobic tower top structure. Background Art

[0002] IC (internal circulation) anaerobic towers, also known as internal circulation anaerobic reactors, are used to treat organic wastewater. The organic wastewater circulates within the IC anaerobic tower, which is populated by anaerobic microorganisms. These microorganisms degrade organic matter in the wastewater into biogas and inorganic matter, ensuring that the wastewater meets discharge standards. IC anaerobic towers are widely used in the papermaking industry.

[0003] The top of the existing IC anaerobic tower adopts a movable hatch structure, which has the problem of biogas escaping to the external environment.

[0004] CN214654289U discloses an IC anaerobic tower, comprising a tower body having a hollow cylindrical structure, a gas-liquid separator disposed on top of the tower body, the gas-liquid separator being a hollow cylindrical structure, a plurality of pipes disposed within the gas-liquid separator, a water inlet pipe connected in series to one side of the bottom of the tower body, a water outlet pipe connected in series to one side of the gas-liquid separator, and a biogas collection pipe connected in series to the top of the gas-liquid separator, the water inlet pipe, the water outlet pipe, and the biogas collection pipe being made of metal, a mixing zone disposed within the tower body, a first anaerobic zone disposed on top of the mixing zone, a second anaerobic zone disposed on top of the first anaerobic zone, a sedimentation zone disposed on top of the second anaerobic zone, and a gas-liquid separation zone disposed on top of the sedimentation zone. The IC anaerobic tower, through the provision of the first and second anaerobic zones, allows wastewater to be treated in separate zones, thereby improving wastewater treatment efficiency. Furthermore, the tower body has fewer internal components, making installation and operation easier and more practical.

[0005] In the technical solution of the above patent document, the gas-liquid separator arranged on the top of the tower body sends the biogas generated inside the tower body to the biogas cabinet arranged outside the tower body through the biogas collection pipe, which does not fully utilize the space.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A novel IC anaerobic tower top structure comprises a tower body, a tower top arranged on the tower body, and a biogas chamber arranged on the tower top and connected to an exhaust pipe arranged on the tower top; an air inlet pipe is provided at a position of the biogas chamber corresponding to the tower top.

[0009] Furthermore, the biogas chamber also includes: an outer layer; an inner layer, arranged inside the outer layer; the outer layer, the inner layer and the tower top form a pressure regulating area, and the inner layer and the tower top form a gas storage area; the pressure regulating area and the gas storage area are sealed to each other.

[0010] Furthermore, the biogas chamber further comprises: a pressure regulating device, which is arranged on the top of the tower, and a pressure regulating pipe passes through the outer layer and is connected with the pressure regulating area.

[0011] Furthermore, the biogas chamber further comprises: a bracket, an end of which is arranged on the top of the tower and connected to the outer layer to support the outer layer.

DETAILED DESCRIPTION

[0028] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0029] Example 1

[0030] A new type of IC anaerobic tower top structure, such as Figure 1-Figure 4 As shown, it includes a tower body 1, a tower top 2 arranged on the tower body 1, and also includes: a biogas chamber 3, which is arranged on the tower top 2 and is connected to the exhaust pipe 23 arranged on the tower top 2; an air inlet pipe 24 is provided at the position of the biogas chamber 3 corresponding to the tower top 2.

[0031] The top 2 of the tower is equipped with a positive and negative pressure protector 21 and a gas-liquid separator 22; the positive and negative pressure protectors are used to make corresponding pressure adjustments according to the internal pressure of the tower body to ensure the normal operation of the tower body; the gas-liquid separator is used to separate the gas generated by the reaction in the tower body and remove the solution entrained by the gas when it is discharged.

[0032] Valves can be provided on the air inlet pipe and the exhaust pipe, and the valves can be solenoid valves.

[0033] The exhaust pipe installed in the biogas chamber is used to discharge the collected biogas to other places for utilization; the air inlet pipe installed on the top of the tower allows the biogas generated in the tower to directly enter the biogas chamber, which not only facilitates collection but also makes the biogas collection more complete.

[0034] Before use, place the biogas chamber on the top of the tower. After installing the biogas chamber, open the valve of the air inlet pipe to allow the gas generated by the reaction inside the tower to enter the biogas chamber. When the gas in the biogas chamber needs to be discharged for use, open the valve on the exhaust pipe.

[0035] Example 2

[0036] like Figure 1-Figure 4 As shown, the biogas chamber 3 also includes: an outer layer 31; an inner layer 32, which is arranged inside the outer layer 31; the outer layer 31, the inner layer 32, and the tower top 2 enclose a pressure regulating area 33, and the inner layer 32 and the tower top 2 enclose a gas storage area 34; the pressure regulating area 33 and the gas storage area 34 are sealed to each other.

[0037] like Figure 1-Figure 4 As shown, the biogas chamber 3 further includes: a pressure regulating device 35 , which is provided on the tower top 2 ; a pressure regulating pipe 36 passes through the outer layer 31 and is connected to the pressure regulating area 33 .

[0038] like Figure 1-Figure 4 As shown, the biogas chamber 3 further includes: a bracket 37 , an end of which is disposed on the tower top 2 and connected to the outer layer 31 to support the outer layer 31 .

[0039] like Figure 1-Figure 4 As shown, the biogas chamber 3 is hemispherical.

[0040] like Figure 1-Figure 4 As shown, the biogas chamber 3 further includes: a first pressure sensor 38 , which is arranged on the inner wall of the outer layer 31 .

[0041] like Figure 1-Figure 4 As shown, the biogas chamber 3 further includes: a second pressure sensor 39 , which is arranged on the inner wall of the inner layer 32 .

[0042] like Figure 1-Figure 4 As shown, the inner layer 32 is made of soft material. The tower top 2 is an umbrella-shaped structure with a high middle and low surroundings.

[0043] The biogas chamber is divided into an outer layer and an inner layer. The outer layer can be supported by a bracket so that the inner layer has space to expand after the biogas enters. Moreover, the outer layer also protects the inner layer. The inner layer is made of soft material. When the gas enters the gas storage area through the air inlet pipe, it will gradually support the inner layer to facilitate the storage of biogas. Moreover, the inner layer is made of soft material, which is also convenient for transportation and installation. The materials used for the inner and outer layers are all existing materials.

[0044] The first pressure sensor is used to monitor the air pressure in the pressure regulating area. When the pressure in the pressure regulating area is significantly different from the air pressure in the inner layer, the inner layer may be deformed by the pressure, affecting its normal use. The pressure regulating area can be adjusted by inflating or exhausting the pressure regulating area through the pressure regulating device to keep it within the appropriate pressure range.

[0045] The second pressure sensor is used to monitor the air pressure of the inner layer. When the pressure inside the inner layer is high, it indicates that the internal biogas pressure is high. At this time, the valve on the exhaust pipe can be opened to discharge the biogas to the external collection box. After the pressure of the inner layer drops to the appropriate range, the valve on the exhaust pipe can be closed.

[0046] A flat installation area is provided at the top of the tower, which is the highest point of the tower top and is higher than the surrounding area of ​​the tower top; the installation area is flat, which is convenient for installing the biogas chamber.

[0047] In order to improve operational efficiency and the safety of operators, a controller can also be set on the side or outside of the tower body. The controller can be connected to the positive and negative pressure protector, the pressure regulating device, the solenoid valve, the first pressure sensor, and the second pressure sensor so that the start and stop of the above-mentioned electrical components can be controlled by notifying them, thereby improving the convenience of operation.

[0048] The pressure regulating device, the first pressure sensor, the second pressure sensor and the solenoid valve involved in the present utility model are not the innovation points created by the present invention, and the specific models are not described in detail.

[0049] The improvement of the present application lies in the top structure of the tower, and does not involve the tower body and its internal structure. The tower body and its internal structure and other components can use existing technology.
