Abstract

The utility model relates to heating system pipeline equipment, and in particular relates to a heating system pipeline impurity settling device. The technical scheme of the heating system pipeline impurity settling device is as follows: the heating system pipeline impurity settling device comprises a first water return major line, a thickened pipe, a second water return major line, an impurity flow guide plate, a gravity settling tank and a blowdown apparatus; the thickened pipe is fixed between the first water return major line and the second water return major line; the cambered impurity flow guide plate is mounted inside the thickened pipe; a settling opening is formed on the lower part of the impurity flow guide plate; the gravity settling tank is arranged vertically; and the blowdown apparatus is arranged at the bottom of the gravity settling tank. The heating system pipeline impurity settling device has the beneficial effects that the thickened pipe section is added to any part of the previous water return header before entering a circulating water pump and a section of impurity speed reducing settling zone is provided artificially to achieve the effect of reducing the liquid flow rate, and consequently, particles are blocked and collected by the flow guide plate under the action of gravity, and finally removed through the blowdown apparatus; and the heating system pipeline impurity settling device is applicable for various pipelines for conveying impurity-containing liquids.

Description

Heating system pipeline impurity sedimentation device

Technical field

The utility model relates to a kind of heating system pipe-line equipment, particularly a kind of heating system pipeline impurity sedimentation device.

Background technology

Heating pipe network inside is because of reasons such as seasonality stops warming up, construction, water quality, oxygen corrosion, can produce at pipe interior the particulate matter such as slag rust, silt, incrustation scale, run duration can enter the facilities such as water circulating pump, boiler, interchanger, indoor pipeline along with systemic circulation inner, causes operation troubless such as damaging water pump impeller, boiler water tube obstruction, interchanger and the obstruction of indoor heating equipment runner.

Summary of the invention

The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of heating system pipeline impurity sedimentation device is provided.

Its technical scheme is: comprise the first backwater bus, add extra heavy pipe, the second backwater bus, impurity flow deflector, gravity settler, blowdown apparatus, the described extra heavy pipe that adds is fixed between the first backwater bus and the second backwater bus, the impurity flow deflector of arc is installed in the described inside that adds extra heavy pipe, sedimentation mouth is opened in impurity flow deflector below, vertical gravity settler is set, and the bottom of gravity settler is provided with blowdown apparatus.

The above-mentioned caliber that adds extra heavy pipe is 1.5-2 times of import and export caliber, the horizontal length that adds extra heavy pipe is himself caliber 2-3 times.

The residue circulation area of above-mentioned impurity flow deflector installation place is not less than the sectional area of import and export.

Above-mentioned blowdown apparatus is provided with sewage draining valve.

The beneficial effects of the utility model are: before the female pipe of original backwater enters water circulating pump, any place sets up overstriking pipeline section, one section of impurity deceleration negative area is artificially set, reach the effect that flow rate of liquid reduces, make particulate matter under action of gravity, after flow deflector stops, collects, natural subsidence is also finally got rid of impurity by blowdown apparatus; Be applicable to carry the transport pipe of all kinds of contaminated liquids.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model;

In upper figure: the first backwater bus 1, add extra heavy pipe 2, the second backwater bus 3, impurity flow deflector 4, gravity settler 5, blowdown apparatus 6, sewage draining valve 7.

Embodiment

By reference to the accompanying drawings 1, the utility model will be further described:

The utility model comprises the first backwater bus 1, adds extra heavy pipe 2, the second backwater bus 3, impurity flow deflector 4, gravity settler 5, blowdown apparatus 6, the described extra heavy pipe 2 that adds is fixed between the first backwater bus 1 and the second backwater bus 3, the impurity flow deflector 4 of arc is installed in the described inside that adds extra heavy pipe 2, sedimentation mouth is opened in impurity flow deflector 4 belows, vertical gravity settler 5 is set, the bottom of gravity settler 5 is provided with blowdown apparatus 6, and blowdown apparatus 6 is provided with sewage draining valve 7, is convenient to blowdown operation.

Wherein, the caliber that adds extra heavy pipe 2 is 1.5-2 times of import and export caliber, to reach the sedimentation object of enlarging volume, reduction flow velocity; The horizontal length that adds extra heavy pipe 2 is himself caliber 2-3 times, the undersized weak effect that slows down, is unfavorable for impurity sedimentation; Otherwise can make water capacity excessive, destroy local support Design parameter.

In addition, the residue circulation area of impurity flow deflector 4 installation places is not less than the sectional area of import and export, to guarantee the design circulation parameter of original system.

The large I of slurry tank determines according to the blowdown frequency, and the intensive straight length mode of can directly taking of the blowdown frequency is connected to ground level, otherwise should strengthen volume, can extend blowdown interval time, reduce blowdown number of times.

Principle of work of the present utility model is:

The liquid of original return piping inside enters of the present utility model adding after extra heavy pipe 2, because adding extra heavy pipe 2 internal capacities, increases, and makes flow rate of liquid rapid drawdown, and liquid washes away particulate contamination meeting natural subsidence under the effect of gravity of carrying secretly in pipeline; Impurity flow deflector has played guiding, the collecting action of impurity; By the timely blowdown to bottom slurry tank, can remove at any time the impurity of inside deposition.
