a decontamination device

Abstract

The invention relates to a cleaner, which comprises a cleaner barrel body, wherein the cleaner barrel body is provided with a filtering screen, the filtering screen is arranged vertical to the bottom of the cleaner barrel body, the cleaner barrel body is divided into two parts, namely, a non-filtering area and a filtering area, by the filtering screen, a partitioning plate is arranged at the lower part of the non-filtering part, and a gap between the partitioning plate and the filtering screen is 50-80mm; meanwhile, the partitioning plate keeps a downward inclined angle of 4-8 degrees, a dirt collecting pool is formed by means of the partitioning plate and the bottom of the cleaner barrel body, and a pipeline is arranged at the bottom of the cleaner barrel body of the dirt collecting pool part and is controlled by a backflush valve; and the cleaner is arranged in a whole inclination angle of 20-50 degrees. Because the cleaner is arranged in an inclined way, impurities and suspensions on the filtering screen have a self-cleaning capability under the impact of water flow, and flow into the specifically-designed dirt collecting pool, therefore secondary blockage caused by water flow perturbance is avoided, the water flow can be ensured to be unimpeded, the resistance loss is reduced, meanwhile, dirt can be cleared conveniently.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air conditioning, in particular to a decontamination device. Background technique [0002] The circulation in the field of HVAC contains a lot of impurities and suspended solids. Although there are many types and forms of decontamination devices, the main problem is that impurities and suspended solids are easy to hang or stick in the decontamination devices under the disturbance of water flow. The filter screen is blocked, resulting in a large loss of resistance and a waste of energy. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a decontamination device that avoids secondary blockage caused by water flow disturbance, thereby ensuring smooth flow of water and facilitating cleaning of dirt. [0004] In order to achieve the above object, the technical scheme that the present inv...
