Runoff long-bag low-pressure pulse bag type dust collector

The invention relates to a runoff long-bag low-pressure pulse bag type dust collector. At present, a blowing pulse dust collector has the defect that a filter bag has the troublesome process of check and replacement and is easy to interfere by weather factors, the defect that the service life of the filter bag is shortened due to the extraordinary strong scour of high-pressure airflow on the filter bag, the defect that a chimney flue is not closed completely due to expansion caused by heat and contraction caused by cold in equipment, and other defects. The bag type dust collector comprises a group of single bag type dust collectors and a controller thereof, wherein the controller comprises a personal computer (PC) cabinet (25); the PC cabinet is respectively connected with an industrial control computer (26), a programmed logic controller (27), a motor control center (28), a field control case (29), a temperature sensor (44) arranged on an inlet chimney flue of each single bag type dust ...

Uniform surface water collecting apparatus

The invention relates to a uniform surface water collecting apparatus. At present, the precipitation technique applied in water treatment mainly comprises a tail end water collecting sedimentation tank, a surface water collecting apparatus, and the like, wherein the openings on the front and the rear parts of the surface water collecting apparatus are the same in size and number to cause nonuniform water distribution of the front and the rear parts, the flow rate at the front end is too high to produce feculent yielding water at the front end and qualified yielding water at the rear end, and the precipitation efficiency is influenced caused by substandard overall yielding water. The uniform surface water collecting apparatus comprises a groove body (1), wherein through holes (2) are formed on one side or both sides of the groove body, and the through holes are dense along the water flow direction in sequence. The product is used in the fields of water treatment and chemical industry.

Water treatment project monitoring system based on wireless sensor network

The application relates to a water treatment project monitoring system based on a wireless sensor network. As present sewage treatment equipment has limited processing ability to use PLC data and a slow running speed, further improvement in system performance is restricted. The system comprises a central control system (2), which is connected with a group of wireless sensor network nodes (1) and comprises an industrial personal computer (6). The industrial personal computer (6) is connected with a wireless sensor master station (7). The wireless sensor network node comprises a data collecting module (3) which is connected with a data processing and controlling module (4). The data processing and controlling module is connected with a communication module (5). The system is used for monitoring the system of the sewage treatment equipment.

Dispersible tablets containing valsartan and amlodipine besylate and preparation method thereof

The invention discloses to dispersible tablets containing valsartan and amlodipine besylate and a preparation method thereof, and relates to medicament dispersible tablets and the preparation method thereof, solving the problem of poor stability, slow disintegration and dissolution, low oral bioavailability and high cost existing in the traditional medicine containing valsartan and amlodipine besylate.
