A negative pressure carbon removal and water temporary hardness removal equipment

Abstract

The invention discloses a negative pressure carbon removal and water temporary hardness removal device, which comprises a sealed tank, a vacuum pump is arranged on the top of the sealed tank, and the sealed tank is sequentially divided into a spraying area, a packing area and a water collection area from top to bottom, and the spraying area After mixing the acid and the water to be treated, the liquid is sprayed to the filling area, and the carbon dioxide gas in the water is separated from the water in the filling area. The carbon dioxide gas is pumped out by the vacuum pump on the top of the sealed tank and discharged from the air outlet on the vacuum pump to remove the water flow of the carbon dioxide gas. To the catchment area for collection; the principle is to remove HCO3‑ in water, the pumping unit uses a vacuum pump to maintain a negative pressure in the airtight barrel, and diffuses CO2 out of the liquid phase, and the function of the packing unit is to increase the contact area between water and the outside world , improve the efficiency of CO2 removal, and the water outlet unit collects and discharges the water. The functional units of the equipment are compactly connected, the principle is simple, the installation and disassembly are convenient, and it has a high scale removal rate for raw water with high temporary hardness.

Description

technical field [0001] The invention relates to equipment in the technical field of water supply, in particular to equipment for removing carbon and temporary hardness in water under negative pressure. 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 environm...
