Water purification system of biogas water heater

Abstract

The invention discloses a water purification system of a biogas water heater. The water purification system comprises the biogas water heater, a water purifier, a heat exchanger, a heat exchange pipeline, a conductivity sensor, a first proportional valve, a second proportional valve and a controller, wherein a circulating water outlet of the biogas water heater is connected to a water inlet of theheat exchange pipeline and a water inlet of the water purifier through first three-way valves; a circulating water inlet of the biogas water heater is connected to a water outlet of the heat exchangepipeline and a water outlet of the water purifier through second three-way valves; the first proportional valve is arranged on a circulating water return pipeline; the second proportional valve is arranged on a water inlet pipeline of the water purifier; the conductivity sensor is arranged inside the biogas water heater; the signal output end of the conductivity sensor is connected to the controller; and the controller is connected to the control end of the first proportional valve and the control end of the second proportional valve. The water purification system realizes the intelligent water purification through the conductivity sensor, the controller, the first proportional valve and the second proportional valve.

Description

technical field [0001] The invention relates to the field of water purification systems, in particular to a water purification system for biogas hot water heaters. Background technique [0002] It is easy to obtain biogas in the treatment of livestock and poultry waste, and biogas water heaters can make good use of this biogas, but the waste treatment sites of livestock and poultry are generally located in remote areas, and the surface water and groundwater in these remote areas generally contain A small amount of suspended solids, calcium, manganese and other metal ions, the use of such surface water and groundwater is easy to generate scale in the biogas water heater, which increases the maintenance frequency, maintenance difficulty and maintenance cost of the biogas water heater equipment. Contents of the invention [0003] The purpose of the present invention is to provide a biogas water heater water purification system, which realizes intelligent water purification. ...
