Hemodialysis water production equipment with main machine capable of being thermally disinfected and temperature compensation and disinfection method of hemodialysis water production equipment

Abstract

The invention relates to hemodialysis water production equipment with a main machine capable of being thermally disinfected. The hemodialysis water production equipment comprises a raw water pump, a quartz sand filter, an activated carbon filter, a softening filter, a precision filter, a first heater, a balancer, a first-stage high-pressure pump, a first-stage reverse osmosis membrane system, a second-stage high-pressure pump, a second-stage reverse osmosis membrane system, a second heater, a hot disinfection water tank, a circulating pipeline and a ward pipeline. According to the hemodialysis water production equipment , a sanitary reverse osmosis membrane element capable of performing thermal disinfection is adopted, two heaters consisting of a plurality of electric heating rods are additionally arranged in the equipment to heat water flow in a pipeline, and hot water at 85-90 DEG C is adopted to perform thermal disinfection or chemical disinfection on a reverse osmosis system pipeline and a reverse osmosis membrane; through temperature compensation, an electric heater heats the water flow in the pipeline by 10-15 DEG C, so that the problem that the water yield of the reverse osmosis system is reduced due to too low temperature of tap water in winter is also solved; the host pipeline microbial and bacterial breeding problem is solved; and a new type of valve is adopted in an equipment pipeline, the mute effect is achieved, and the problem that equipment noise is large is solved.

Description

technical field [0001] The invention relates to the field of medical pure water, in particular to a water-making device for hemodialysis with a host that can be thermally sterilized and a temperature compensation and disinfection method thereof. Background technique [0002] In the usual water-making equipment for hemodialysis, the equipment mainly consists of raw water pump, quartz sand filter, activated carbon filter, softening filter, balancer, primary high-pressure pump, primary RO system, secondary high-pressure pump, secondary Composed of RO system and electrical control system. At present, the water-making equipment for hemodialysis mainly has the following disadvantages: [0003] (1) No heat disinfection of the RO host. At present, the equipment on the market mainly uses thermal disinfection devices developed by their respective companies to thermally disinfect the external circulation pipeline that supplies water to the hemodialysis machine to control the problem ...
