Abstract
A backflushing type filtering device of a heat exchange station. The mechanism is adopted to filter the filter screen, the filter screen is easy to block, the cleaning is not facilitated for a long time, and meanwhile, the existing filter device cannot clean the filter screen. The invention comprises the following steps: the water inlet pipe (1) and the water outlet pipe (6), the water inlet pipe and the water outlet pipe are communicated through two branch pipes (2), a filter (5) is arranged on each branch pipe, and a vertically downward water outlet pipe (4) is arranged on the front side of each filter on each branch pipe. The invention is used for backflushing filtration of the heat exchange station.
Description
Technical Field
The invention relates to a backflushing type filtering device of a heat exchange station.
Background
The heating power station is a place where heat is concentrated and exchanged, and is divided into a direct supply station and an indirect supply station according to a heat supply mode, wherein the direct supply station and the indirect supply station are directly supplied to users by a power plant, the temperature is high, heat energy is wasted, waste heat is a product of waste heat welfare heat supply of the power plant initially, impurities and rust generated by rust inside a heat supply pipeline are used for a long time in a secondary circulation pipe network of the heat supply system, if even cleaning and filtering cannot be obtained, the heat supply pipeline is easy to block, a mechanism is adopted to filter a filter screen, the filter screen is easy to block, the cleaning is long, and meanwhile, the conventional filter device cannot clean the filter screen.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a backflushing type filtering device of a heat exchange station, which solves the problems in the background art.
The above object is achieved by the following technical scheme:
a backflushing type filtering device of a heat exchange station comprises a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is communicated with the water outlet pipe through two branch pipes, a filter is arranged on each branch pipe, and a water outlet pipe which is vertically downward is arranged on the front side of each branch pipe and positioned on the filter.
The back flushing type filtering device of the heat exchange station is characterized in that a branch valve is respectively fixed on two sides of each branch pipe, which are positioned on the filter.
The back flushing type filtering device of the heat exchange station is characterized in that an inlet valve is arranged on the water inlet pipe.
The back flushing type filtering device of the heat exchange station is characterized in that an outlet valve is arranged on the water outlet pipe.
Advantageous effects
1. According to the invention, by arranging the two branch pipes, when water is supplied, water can pass through the two branch pipes respectively, and meanwhile, when one filter screen is blocked, the filter screen can be cleaned by utilizing the backflushing of the water flow, and the cleaned sewage is discharged through the water discharge pipe, so that the filter can be cleaned automatically without disassembly.
Drawings
FIG. 1 is a top view of the present invention;
FIG. 2 is a front view of the present invention;
in the figure: 1. a water inlet pipe; 2. a branch pipe; 3. a sub-valve; 4. a water drain pipe; 5. a filter; 6. a water outlet pipe; 7. an outlet valve; 8. an inlet valve.
Detailed Description
A backflushing type filtering device of a heat exchange station comprises a water inlet pipe 1 and a water outlet pipe 6, wherein the water inlet pipe is communicated with the water outlet pipe through two branch pipes 2, a filter 5 is arranged on each branch pipe, and a water outlet pipe 4 which is vertically downward is arranged on the front side of each branch pipe and positioned on the filter.
The back flushing type filtering device of the heat exchange station is characterized in that a branch valve 3 is respectively fixed on two sides of each branch pipe, which are positioned on the filter.
The back flushing type filtering device of the heat exchange station is characterized in that an inlet valve 8 is arranged on the water inlet pipe.
The back flushing type filtering device of the heat exchange station is characterized in that an outlet valve 7 is arranged on the water outlet pipe.
When the filter is used, the inlet valve, the outlet valve and the branch valves on the two branch pipes are all opened, the valve on the water drain pipe is closed, water is filtered through the branch pipes, when one of the filters is blocked, the branch valve on the water inlet end of the blocked filter end is closed, the outlet valve is closed, the valve on the water drain pipe at the front end of the filter is opened, water on the other branch pipe enters the branch pipe to back wash the filter screen of the filter, the washed sewage is discharged through the water drain pipe until the water is clear, and then the valve on the water drain pipe is closed, so that the back wash of the filter is realized.
