Description

Technical Field

[0001] The utility model relates to the technical field of construction waste gas treatment, in particular to a carbon neutralization treatment device for buildings. Background Art

[0002] Carbon neutrality refers to carbon emission reduction, among which reducing carbon dioxide emissions is an important way to achieve "carbon neutrality". During the construction process, a lot of waste gas containing carbon dioxide will inevitably be generated. If these waste gases containing carbon dioxide are not treated and directly discharged into the atmosphere, the total carbon emissions will exceed the standard and cannot meet the relevant environmental protection requirements.

[0003] For example, a construction carbon neutrality emission treatment device with publication number CN215027551U is provided. By providing a primary absorption tank with a spray chamber and a liquid storage chamber, a spiral conveying pipe with a vent is provided in the liquid storage chamber, a gas uniform distribution plate 2 and a gas uniform distribution plate 1 are provided in the spray chamber, and a secondary absorption box with a packing layer is provided. This facilitates carbon neutrality emission treatment of waste gas containing carbon dioxide during construction. However, in order to allow the waste gas to fully contact with the reaction liquid, the device is provided with a relatively high liquid storage chamber and a spray chamber, which makes the device relatively large in size. In addition, a secondary absorption box is provided above the spray chamber. The secondary absorption box is located at the top of the device, which is very inconvenient when replacing the packing layer inside it. For this reason, a carbon neutrality treatment device for buildings is proposed for improvement. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] To this end, one purpose of the present invention is to propose a building carbon neutralization treatment device to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a building carbon neutralization treatment device, including a treatment box, a liquid storage tank is arranged on the top of the treatment box, a spray chamber and an adsorption chamber are arranged in the treatment box, a through pipe is arranged between the spray chamber and the adsorption chamber, an air intake pipe is arranged on one side of the spray chamber, a vortex pipe is fixedly connected to the bottom end of the air intake pipe, a diverter pipe is fixedly connected to the top of the vortex pipe, a drain pipe is arranged at the bottom of the spray chamber, and a spray shower is arranged at the upper part of the spray chamber;

[0007] The processing box is provided with a box door at the position of the adsorption chamber, a plurality of partitions are provided in the adsorption chamber, a packing layer is provided between the partitions, an air hole is provided at one end of the partition, and an exhaust pipe is provided at one side of the adsorption chamber.

[0008] Preferably, any of the above solutions is that the bottom of the processing tank is provided with supporting feet, and one side of the liquid storage tank is provided with a water inlet pipe.

[0009] Preferably, in any of the above schemes, a blocking plate is provided between the spray chamber and the adsorption chamber, and the through pipe is provided above the blocking plate.

[0010] The above technical solution is adopted: the treatment box provides space for carbon neutralization treatment work, and the legs set at the bottom support it to ensure its stability. The liquid storage tank set on the top of the treatment box is used to store alkaline absorption liquid to provide absorption liquid for the spray component. The water inlet pipe can easily add absorption liquid to the liquid storage tank. The spray chamber is used for spray absorption work, and the adsorption chamber is used for subsequent adsorption work. The two work together to make the building waste gas undergo double treatment and improve the purification degree of the building waste gas after treatment.

[0011] Preferably, any of the above schemes is that valves are provided on the air inlet pipe, the drain pipe and the exhaust pipe, and the vortex pipe is fixed at the bottom of the spray chamber.

[0012] Preferably, any of the above schemes has a plurality of diversion pipes which are evenly arranged on the vortex tube, and a pipe connected to a liquid storage tank is provided at the upper end of the spray shower.

[0013] The above technical solution is adopted: the air inlet pipe is used to input the construction waste gas to be treated into the device. The vortex tube moves the construction waste gas to be treated to various positions at the bottom of the spray chamber, and the diverter pipe discharges the construction waste gas in the vortex tube and disperses the construction waste gas to various positions in the spray chamber. The spray shower can evenly spray the absorption liquid in the storage tank to various positions in the spray chamber. When using, first turn on the spray shower to spray a certain amount of absorption liquid into the spray chamber, and then input the construction waste gas to be treated into the air inlet pipe. The waste gas passes through the vortex tube and enters the spray chamber from the diverter pipe. The gas and the absorption liquid are fully in contact in the spray chamber, and the absorption liquid absorbs the carbon dioxide in the waste gas.

[0014] Preferably, any of the above schemes is provided with a handle on the box door, and solid sodium hydroxide particles are provided in the packing layer.

[0015] Preferably, any of the above schemes is that the air holes are arranged at the bottom and top of the corresponding partition in sequence from left to right and in this cycle.

[0016] The above technical solution is adopted: the box door can facilitate the staff to replace the packing layer in the adsorption chamber. After the construction waste gas is treated in the spray chamber, it enters the adsorption chamber through the through pipe, and passes through each packing layer and the air holes in turn. Since the air holes are arranged in a cycle at the bottom and top of the partition, the gas flow route in the adsorption chamber is S-shaped, and the residual carbon dioxide in the gas is absorbed and reacted by the sodium hydroxide solid particles in the packing layer, realizing the carbon neutralization treatment of the construction waste gas. The gas is finally discharged from the exhaust pipe.

[0017] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0018] 1. The carbon neutralization treatment device for buildings is provided with structures such as a treatment box, a liquid storage tank, a spray chamber, and an adsorption chamber.

After the building waste gas is treated in the spray chamber, it enters the adsorption chamber through the through pipe, and passes through each packing layer and the air holes in turn. Since the air holes are arranged in a cycle at the bottom and top of the partition, the gas flow route in the adsorption chamber is S-shaped, and the residual carbon dioxide in the gas is absorbed and reacted by the sodium hydroxide solid particles in the packing layer, so as to realize the carbon neutralization treatment of the building waste gas. The gas is finally discharged from the exhaust pipe. Through reasonable structural design, the volume of the device is greatly reduced, the cost of the device is reduced, and the practicality is stronger.
