Description
Technical Field
The utility model belongs to the technical field of heat supply network systems, and particularly relates to a heat supply network backwater filter screen bypass system.
Background
In the heat supply network, the return water filter screen plays a role in filtering return water, and after long-time operation, the return water filter screen accumulates impurities to cause blockage, so that the pressure difference between two sides of the return water filter screen is large, great hidden danger is brought to safe and stable operation of the heat supply network system, and heat supply needs to be stopped when the return water filter screen is cleaned during operation of the heat supply network, and therefore, the economic benefit is very influenced.
The main problems that exist at present: the heat supply network external net system has construction projects every year, because the heat supply network external net system can not be effectively protected in the installation and construction process, construction wastes such as sand, stones, welding rod heads and the like are stored in the system, after the heat supply network runs, the heat supply network flows back to a return water filter screen through the system, so that the filter screen is blocked, the phenomenon of large differential pressure is caused, because the return water filter screen of the original heat supply network pipeline is not provided with a bypass, the return water filter screen can not be cleaned in the running process, and the potential safety hazards of heat stop and heat limitation exist.

The utility model provides a bypass system of a return water filter screen of a heat supply network.
The technical scheme of the utility model is as follows: the utility model provides a heat supply network return water filter screen bypass system, its characterized in that, includes return water main road and return water bypass, the return water main road includes preceding insulated door, return water filter screen, back insulated door, the door that drains, the return water bypass includes water inlet, bypass door, delivery port, the water inlet is insulated door the left side in the front, the delivery port is on back insulated door the right, return water main road and return water bypass are parallelly connected through water inlet and delivery port.
Furthermore, the backwater filter screen is connected with a water drain door.
The scheme is further that a pressure detection device is arranged on the water return filter screen.
The scheme is further that a temperature detection device is arranged on the water return filter screen.
Furthermore, the front isolation door and the rear isolation door are respectively connected with a heat supply network DCS system.
The utility model has the advantages that: the utility model has simple design, is designed and transformed on the basis of the original return water filter screen of the heat supply network, is additionally provided with the isolating door and the bypass door, and is transformed into a bypass system for cleaning the return water filter screen under the condition that the heat supply network does not stop heating, thereby greatly improving the working efficiency, effectively solving the problem that the original heat supply network system needs to stop heating to clean the return water filter screen, and having very obvious economic benefit.
Drawings
FIG. 1 is a schematic view of a heat supply network return water screen bypass system of the present invention;
wherein: 1. the water inlet valve comprises a front isolation door, a water return filter screen, a rear isolation door, a water drain door, a bypass door, a water inlet door, a water outlet door and a water outlet door, wherein the front isolation door is 2, the water return filter screen is 3, the rear isolation door is 4, and the water outlet door is 5.
Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a person skilled in the art can, without any creative effort, fully implement the present invention.
One embodiment of the utility model: the utility model provides a heat supply network return water filter screen bypass system, its characterized in that, includes return water main road and return water bypass, the return water main road includes preceding insulated door 1, return water filter screen 2, back insulated door 3, discharge door 4, the return water bypass includes water inlet 6, bypass door 5, delivery port 7, water inlet 6 is on the left of insulated door 1 in the front, delivery port 7 is on the right of insulated door 3 in the back, return water main road and return water bypass are connected in parallel through water inlet 6 and delivery port 7.
Preferably, the backwater filter screen 2 is connected with a water discharge door 4.
Preferably, the return water filter screen 2 is provided with a pressure detection device.
Preferably, the return water filter screen 2 is provided with a temperature detection device.
Preferably, the front isolation door 1 and the rear isolation door 3 are respectively connected with a heat supply network DCS system.
The specific implementation mode of the utility model is as follows: when the heat supply network operates normally, the heat supply network DCS system monitors the data of pressure and temperature measuring points in front of and behind the backwater filter screen in real time, at the moment, the bypass door 5 and the drain door 4 are in a closed state, and backwater of the heat supply network flows through the front isolation door 1, the backwater filter screen 2 and the rear isolation door 3 in sequence; when the heat supply network DCS system monitors that the pressure difference of the return water filter screen is large, the bypass door 5 is opened, then the front isolation door 1 and the rear isolation door 3 are closed, so that return water of the heat supply network flows through the water inlet 6, the bypass door 5 and the water outlet 7 in sequence, the operation of the heat supply network system is not affected, and finally, a maintenance worker opens the water discharge door 4 to clean the return water filter screen 2; after the return water filter screen 2 is cleaned, the water drain door 4 is closed firstly, then the front isolation door 1 and the rear isolation door 3 are opened, finally the bypass door 5 is closed, and the operation of the heat supply network returns to normal.
While the preferred embodiments of the utility model have been described, it is to be understood that the utility model is not limited to the precise embodiments described, and that equipment and structures not described in detail are understood to be practiced as commonly known in the art; any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention by those skilled in the art can be made without departing from the technical scope of the present invention, and still fall within the protection scope of the technical solution of the present invention.
