Carbon dioxide filling and diffusing device

Technical Field

The utility model relates to a carbon dioxide filling diffusion equipment mainly is applied to municipal works technical field.

Background

In the field of municipal engineering water supply, the application of seawater desalination is becoming more and more common. The effluent quality of the seawater desalination plant is high, the seawater desalination plant basically does not contain mineral substances, the hardness and the alkalinity are very low, the phenomenon of red water or yellow water in a water distribution pipe network is often caused when the seawater desalination plant is directly used for municipal water supply, and certain risks exist to human health when the low-alkalinity and low-hardness desalinated seawater is drunk for a long time. Therefore, in order to ensure the water quality safety of users, the seawater desalination water needs to be mineralized firstly and then enters a municipal pipe network for water supply. At present, the process for desalination and mineralization treatment of seawater generally adopts a process method of carbon dioxide + lime water or carbon dioxide + calcium carbonate. The technological schemes generally require rapid and uniform mixing of carbon dioxide and seawater and require efficient carbon dioxide filling and diffusing devices.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the carbon dioxide filling and diffusing device enables carbon dioxide and seawater to be quickly and uniformly mixed, improves the quality of effluent and is safe to use.

Carbon dioxide filling diffusion equipment, including the carbon dioxide filling pipe, set gradually electrical control valve, gas flowmeter and hand valve according to carbon dioxide's direction of flow on the carbon dioxide filling pipe, carbon dioxide filling pipe end-to-end intercommunication water pipeline distributes between carbon dioxide filling pipe and the water pipeline has the aeration pipe, and it has the aeration hole to distribute on the aeration pipe wall, and the aeration hole sets up to the through-hole.

The electric regulating valve automatically regulates the adding amount of the carbon dioxide according to the water inflow; the gas flowmeter monitors the adding amount of the carbon dioxide on line; the manual valve is used for manually closing or opening the filling pipe.

The carbon dioxide filling pipe is made of stainless steel 316L. The carbon dioxide filling pipe is used for connecting a carbon dioxide gas source and a water conveying pipeline, and the material is stainless steel 316L.

The aeration pipe is made of stainless steel 316L, laser drilling is adopted on the aeration pipe, the aperture is smaller than 1mm, and the total area of the through holes is smaller than 20% of the sectional area of the diffusion pipe.

Every water conveying pipeline correspond and set up three aeration pipes, three aeration pipes staggered arrangement, two adjacent aeration pipe contained angles are 60 degrees, the aeration pipe diameter sets up according to velocity of flow 5 m/s.

The carbon dioxide and water are mixed to have strong corrosivity, and the carbon dioxide diffusion device is made of stainless steel 316L. And calculating the pipe diameter of the carbon dioxide diffusion pipe according to the designed adding amount of the carbon dioxide, and controlling the gas flow velocity to be less than 5 m/s. And (3) on the calculated stainless steel 316L pipeline, forming micropores with the diameter less than 1mm by using laser. The total area of the micropores is less than 20% of the cross section area of the diffusion tube. The carbon dioxide diffusion devices are installed on the main pipeline in a staggered mode, generally three positions are needed, and included angles formed by staggered arrangement are 60 degrees. By using the carbon dioxide diffusion device, the carbon dioxide gas and the seawater can be quickly mixed.

The utility model has the advantages that:

when the device works, carbon dioxide sequentially passes through the filling pipe, the electric regulating valve, the gas flowmeter and the manual valve, and is uniformly distributed in seawater through the aeration pipe, so that the effect of fully mixing the carbon dioxide and the seawater is achieved, and the next mineralization treatment process is conveniently carried out.
