Abstract

The utility model relates to a processing apparatus for water, waste water or sewage. The utility model is provided with a tank body which is a sealed pressure container, the upper part of the cap of the tank body is provided with an air outlet, the side face of the lower part of the tank body is provided with an air inlet hole, the bottom of the tank body is provided with a dirt discharging port, filter screen rails are arranged in the tank body, and corrosion resisting filter materials are filled in the filter screen rails. The utility model is used for chlorine throwing systems so that liquid chlorine is more safely gasified, and the utility model mitigates the impact of high-pressure chlorine for a pipe system and filters and cleans sundries in the chlorine so as to ensure the water quality, having safety.

Description

Chlorine filters the intermediate buffering jar

The utility model relates to the treatment device of a kind of water, waste water or sewage.

The chlorine dosing system has been widely used in the process of purifying waste water.The existing chlorine dosing system of purifying waste water commonly used exists heavy, easily leaks, and is dangerous, is not easy to shortcomings such as automation.Advantages such as Germany makes that the ALLDOS chlorination system has compact structure, precision is higher, negative pressure adds, safe and reliable, automatic switchover, it forms (referring to Fig. 1) by switching valve (1), vacuum valve (2), chlorine bottle (3), manifold (4), safety valve (5) and heater (6) etc.But in use also there is serious problem in this system, liquid chlorine takes place easily run in the COMM communication pvc pipe system, causes the whole frostbite of COMM communication, distortion, and even can not use, and its maintenance expenses height has a strong impact on production.

The purpose of this utility model aims to provide a kind of chlorine dosing system that is used in, and can make liquid chlorine vaporizing safer, relaxes the impact of high pressure chlorine to piping, can filter and remove foreign material in the chlorine, guarantees that the chlorine of water quality filters the intermediate buffering jar.

The utility model is provided with tank body, and it is an airtight pressurized container, and the Cap for tin body top sets out pore, and the tank body lower side is established inlet hole, and tank base is established sewage draining exit, installs the filter screen hurdle in the tank body, filters and fills the corrosion resistance filtering material in the wire net.

Filter the corrosion resistance filtering material of filling in the wire net and can select glass fibre cotton for use.

In tank body, also can fill the filler of corrosion resistance.Filler can be selected granular for use, for example PVC material ball or ABS material ball.To increase the area of contact of chlorine in tank body, reach the effect that the chlorine buffering is filtered.

The working pressure of tank body can select to be no less than 0.8MPa.

During work, the utility model (7) is arranged in the chlorine dosing system of purifying waste water (referring to Fig. 2), chlorine enters tank body from inlet hole, at first in the tank body lower space, there is remaining liquid chlorine (to cause vacuum so far owing to water-blaster in the tank body by the switched system transmission because compare herein in this gasification, it in pressure chlorine cylinder and the manifold end) herein, enter the filter screen hurdle after the gasification, the impurity absorption of chlorine is on the corrosion resistance filtering material in filtering wire net, and the chlorine after the purification sucks switched system from top.Simultaneously and since the tank body space make-up space of filter flask top, the chlorine gas volume is increased, when chlorine dosage changed greatly, the liquid chlorine variation in pressure was less, plays the effect of compensation.

In a word,, make the expansion space that increases jar in the pipeline, make liquid chlorine vaporizing safer, and relaxed of the impact of high pressure chlorine piping owing in the chlorine dosing system of purifying waste water, set up the utility model; Filter the existence of wire net in addition, can remove foreign material such as sulphide and ferric trichloride in the chlorine, guaranteed water quality, and adsorbable residual droplets chlorine; But the variation of throwing chlorine in the bucking-out system simultaneously.It is simple in structure, and is easy to maintenance, does not change other settings of piping, and not needing provides energy in addition, and operating cost is low, and safety reliability is good.

And the existing chlorine dosing system of purifying waste water, because chlorine quality commonly used is stable inadequately, impurities is more, therefore cause the tapered junction plane of pointed cone of switched system (see figure 1) vacuum valve (2) and base to be detained the impurity that has based on sulphide, cause valve to be in normally open, liquid chlorine enters in the switched system by vacuum valve (2) from chlorine bottle (3), manifold (4), causes the PVC frostbite in the system; Because in operating process or too high because of liquid chlorine liquid level in the bottle, or the position is improper, cause liquid chlorine in bottle under the chlorine high pressure (0.7MPa) pour in COMM communication.Like this, cause in the COMM communication PVC system a large amount of heat absorptions of vaporization, temperature is reduced to below the fail temperature-10 ℃, causes piping to destroy.

Fig. 2 is the utility model mounting point schematic representation in the ALLDOS chlorination system.

Fig. 3 is the utility model structural representation.

As shown in Figure 3, the utility model is provided with tank body (11), tank body (11) is the seal-off pressure container of working pressure 〉=0.8MPa, the top of Cap for tin body sets out pore (12), the tank body lower side is established inlet hole (13), and tank base is established sewage draining exit (14), and tank body built-in filters wire net (15), filter wire net (15) interior filled glass fiber cottons (16), filled PVC ball (17) in tank body.In the using process, tank body (11) is erected on the support (18), and its inlet hole (13) is connected with the pipeline of system respectively with air outlet hole (12).
