Problems solved by technology

[0007] Aiming at the problem of high temporary hardness and easy scaling of drinking water at present, the purpose of the present invention is to provide a tower-type drop water removal device for temporary hardness in water, which can get rid of the traditional idea of ​​removing calcium and magnesium ions, and remove HCO in water. 3 - and CO 3 2- From the perspective of reducing the temporary hardness in the water and reducing the generation of scale

Embodiment Construction

[0038] The design concept of the present invention is to design a descaling efficient, fast removal of CO 2 , Easy to operate, easy to install and disassemble, adjustable scale to remove temporary hardness structures of water. After the untreated water is added with the medicine, the water and the medicine (hydrochloric acid) are fully mixed through the static mixer, and the H contained in the water + increase, and HCO in water 3 - The reaction produces H 2 O and CO 2 , when the dissolved CO in water 2 increase, when CO 2 When the amount exceeds the solubility at this temperature, it will continue to diffuse into the air, but when the water depth is deeper, it will form a CO below the water surface. 2 The concentration gradient makes the underlying CO 2 Can not diffuse rapidly into the air. Therefore, the equipment uses the method of multi-stage water drop to reduce the water depth and increase the contact area between the water surface and the air so that the dissolve...

Abstract

The invention discloses an apparatus for removing temporary hardness in water during tower type water fall. The apparatus is used for solving the problems that water having high temporary hardness generates precipitates, forms water scales and the like after being boiled. The apparatus is divided into three stages according to the difference of water purifying units, wherein each pipeline is formed by connecting with flanges; the apparatus is divided into an acid adding and mixing unit, a water fall carbon-removing unit and a water collecting unit. A chemical agent added in the acid adding and mixing unit is hydrochloric acid, the mixing is for a purpose of realizing sufficient mixing reaction of raw water and the chemical agent, and the acid adding and mixing unit has an effect of removing HCO<3-> from water; the water fall carbon-removing unit aims at removing CO2, which is dissolved in water, generated in the reaction of the acid adding and mixing unit; the water collecting unit has an effect of collecting treated water and adding a chemical agent (sodium hydroxide) to adjust pH value to a normal level. The apparatus is compact in connection of various functional units, simple in principle and convenient to mount and dismount, and has high scale removal rate against raw water having high temporary hardness, and the scale of the apparatus can be adjusted according to different requirements.

Description

technical field [0001] The invention relates to equipment in the technical field of water supply, in particular to a tower-type water drop device for removing temporary hardness in water. technical background [0002] Groundwater is an important and high-quality drinking water source for Chinese residents. Large and medium-sized cities generally use surface water sources due to their large water consumption. Surface water sources mainly include rivers, lakes, reservoirs, etc., which are characterized by low hardness, but there are many suspended impurities, organic matter and bacteria, water treatment is relatively complicated, and it is easily affected by the external environment impact and pollution, and use groundwater as a backup water source for the city. Compared with surface water, groundwater has less suspended impurities, less organic matter and bacteria, relatively easy water treatment, and is not easily affected and polluted by the external environment. Groundwat...
