Description
The present invention relates to a 2-bed type filtration filter capable of automatic backwashing according to a pressure change, and more particularly, the filtration network is blocked by a foreign matter in a pretreatment filtration step for measuring contaminants contained in domestic sewage or rivers. In addition, the present invention has been invented to improve the reliability of contamination measurements by automatically cleaning them.
In general, domestic sewage and rivers contain various harmful substances as a result of flowing various wastes indiscriminately with industrial development.
Therefore, in order to grasp changes in water quality management and pollution level, a pollutant measuring device is installed in a river to measure the degree of pollution and change.
The pollutant detector is a device that oxidizes organic substances stably by using a low temperature combustion reaction tube and a catalyst, and removes the contamination of inorganic salts that may occur at high temperature, and then accurately measures the total organic carbon content among the pollutants in the detector. .
However, in the conventional pollutant measuring device, various suspended solids and foreign substances are mixed in an irregular size in a sample that is input for measurement, that is, in a pollutant in a river.
Therefore, when the amount of solid suspended solids in the sample is added to the measuring device to measure the degree of contamination, such as total organic carbon (TOC), there was a problem that the reliability of the measured value is lowered.
In order to solve this problem, in Korean Patent No. 10-0720689, the solid suspended solids in the sample introduced for measurement are mixed in a homogenized state in the sample, and then filtered to a certain size by a filtering network to measure the contamination. A pretreatment filtration device has been proposed that allows samples to be supplied.
The degree of contamination of the sample was initially measured more accurately by the apparatus of the above-described Korean Patent No. 10-0720689.
However, because the sample contains a large amount of contaminants in irregular sizes, it is common to be clogged by the filtering network.
Therefore, in the early stages, the reliability of the measurement diagram was high, but if the filter network was clogged due to repeated use, there was a disadvantage in that the measured value change in the continuously changing sample could not be accurately measured.
In order to solve this problem, an object of the present invention is to provide a filter cleaning device for measuring pollutants that can measure the degree of contamination of the sample more accurately by detecting the clogging of the filter network and automatically cleaning.
It is another object of the present invention to provide a filter cleaning device for measuring pollutants, which allows the administrator to have more convenience because the three operations can be automatically performed without a separate worker.
Still another object of the present invention is to provide a filter cleaning device for measuring pollutants, by which automatic cleaning is performed without stopping the pollutant measuring system, thereby improving the efficiency and reliability of the product.
In order to achieve this object, the present invention, the hollow body is divided into the

Therefore, by automatically washing the filter network, it is possible to measure the contamination level of the sample more accurately.
In addition, since the three operations can be automatically performed semi-permanently without a separate power or operator, to make the manager or operator more convenient, the reliability of the product is improved.
