Description

High-voltage pulse tap water sterilization instrument

The utility model belongs to life, industrial water equipment technical field, is specifically related to a kind of high-voltage pulse drinkable liquid sterilization instrument.

At present, the sterilization and disinfection mode to life, process water commonly used is a heat treated, and this mode is kill bacteria effectively, but sterilization speed is slow, the energy consumption height, and to change the physical and chemical index of water after the heating.Therefore, new sterilization mode becomes the target of scientific research and development.Microwave current sterilization, ultrasonic sterilization, the laser sterilization application of achieving success in succession, the distinguishing feature of this class sterilization method is a non-heat sterilization, can overcome the shortcoming of heat sterilization.But these technology are because of the requirement harshness of its use technology, and the use cost height influences it and promotes the use, and can't really replace the heat sterilization technology and enter industry and life.

The utility model is at the deficiency that existing sterilising technology exists, provide a kind of be widely used in industry and life, utilize high electric field pulse sterilization, cost is low, sterilization rate is high high-voltage pulse tap water sterilization instrument.

Technical solutions of the utility model are as follows:

High-voltage pulse tap water sterilization instrument, if fluid inlet, liquid outlet and the pipeline that is communicated with them, the characteristics of present technique are to establish high-voltage pulse sterilization circuit in the sterilization instrument, the electrode of sterilization circuit is arranged in the pipeline, contact with the water of the pipeline of flowing through, the sterilization circuit provides stable power by power source circuit, controller setting pulse generation circuit, pulse generating circuit connects high voltage generating circuit again, last connection electrode.

The high electric field pulse sterilization belongs to non-heat-sterilization category, with general heat-sterilization essential distinction is arranged.When liquid flow through pulsed electric field, can kill microorganism wherein effectively, and the temperature of food product bodies does not have considerable change (＜10 ℃), thereby has guaranteed that to greatest extent original nutritive ingredient is not destroyed in the water.As working as pulsed electric field (10-30kv/m, pulse width 10 * 10 ^-6-40 * 10 ^-6When s) acting on microorganism (intestinal bacteria, Salmonella thalline etc.) cell in the liquid, will produce corresponding electric field on its film, cause producing on the cytolemma charge separation then.And the electromotive force on acting on its film is when surpassing its threshold value, the inside and outside positive and negative charge magnetism (or the suffered force of compression of film) of film makes film be forced to compression, draught large charge magnetism more is big more, at this moment extra electric field intensity is if equal or a little more than certain threshold value, the temporary operation of cytolemma can also be repaired; When if extra electric field intensity is considerably beyond this threshold value, just will makes film produce irreversible damage, thereby cause tenuigenin excessive and dead.This device can be killed the tens kind bacteria cultures relevant with food effectively.

The advantage of this instrument is as follows:

1. sterilization speed is fast.During sterilization, current are through high-voltage electric field, and bacterium just is killed at once under the high-voltage electric field effect, and the sterilization flow reaches 60ML/S-360ML/S, be fit to multiple occasion under sterilization of liquids.

2. sterilization rate height.To intestinal bacteria, sterilization rates such as Salmonellas reach 100%, and to aspergillus tubigensis, sterilization rates such as yeast are greater than 98%, and once sterilization back water can reach standard for drinking.

3. temperature rise is little.Actual probe temperature rises less than 0.5-1 degree centigrade during sterilization, and is also minimum to the physical and chemical index influence of water.

4。Use easy and simple to handlely, water outlet is promptly sterilized.

5. it is low to consume energy.Power consumption also need not be assisted consumable material less than 1 degree/ton, is the minimum and free of contamination state-of-the art sterilising method of present energy consumption.
