Abstract
The utility model discloses an enhanced heat-exchange shell-tube heat exchanger for anti-fouling and descaling by an ultrasonic wave. Municipal sewage contains large amounts of impurities such as colloids, microorganisms, algae, organic liquid droplets and microscale solid, a lot of dirt is formed on the surface of a heat exchange wall even if the impurities are filtered before entering the heat exchanger, so that the utilization efficiency of heat energy is seriously affected, and the consumption of electric energy and the like is increased. The enhanced heat-exchange shell-tube heat exchanger comprises a shell (1) with a clear water inlet (11) and a clear water outlet (12), wherein a heat exchange tube (2) is arranged inside the shell; the shell is connected with an elliptical head (13) through a tube plate (4); a blow-down valve (5) is arranged on the elliptical head; the elliptical head is connected with an ultrasonic transducer (6), and the ultrasonic transducer is connected with an ultrasonic generator (7). The product is used as a heat exchanger capable of cleaning the dirt subsiding inside the heat exchanger.
Description
Technical field:
The utility model relates to a kind of shell and tube exchanger, the heat-exchanger rig that particularly has ultrasonic air chemoprevention, scale removal and strengthen function.
Background technology:
The sewage source heat pump air-conditioning system adopts the more constant urban original wastewater of temperature as the energy, is a kind of mode of recycling preferably of utilizing waste heat and low-temperature heat source, is turning waste into wealth truly.Because constructivity and the heat transfer characteristic of municipal sewage complexity even carried out filtration treatment before entering heat exchanger, still form sticky foulant at the heat exchange pipeline wall extremely easily, have a strong impact on the utilization ratio of heat energy, may cause heat exchanger to stop up simultaneously.In case fouling, the cleaning of heat exchanger will be very loaded down with trivial details, and large the increasing so that cost has high input has influence on the heat supply and air conditioning of municipal sewage source heat pump air-conditioning system, or even development.
Summary of the invention:
The purpose of this utility model is to make the enhanced heat exchange shell hot type heat exchanger of a kind of ultrasonic wave antiscale, scale removal, can clean out at any time the dirt that is deposited in the heat exchanger.
Above-mentioned purpose realizes by following technical scheme:
The enhanced heat exchange shell hot type heat exchanger of a kind of ultrasonic wave antiscale, scale removal, its composition comprises: with the housing of clear water import, clear water output, in the described housing heat exchanger tube is installed, described housing be connected with ellipse head by tube sheet, described ellipse head is equipped with blowoff valve, described ellipse head is connected with ultrasonic transducer, and described ultrasonic transducer is connected with supersonic generator.
The enhanced heat exchange shell hot type heat exchanger of described ultrasonic wave antiscale, scale removal, described ellipse head has sewage import, outlet of sewer, described end socket inside is equipped with pass partition, and described outlet of sewer place is equipped with described blowoff valve, in the described housing baffle plate is housed.
Beneficial effect:
1. the utility model can be realized preventing and kill off online dirt by ultrasonic transducer and supersonic generator, and the angle of ultrasound wave descaling heat exchanger, corner, edge equipotential are put also and can be realized scale removal, can comprehensively clean heat exchanger.
The setting of the utility model outlet of sewer place blowoff valve can clean out the dirt that is deposited in the heat exchanger at any time, improves heat transfer effect, utilization rate, energy-saving and emission-reduction.
The utility model cost is low, and has reduced environmental pollution and the equipment corrosion wearing and tearing that bring because of chemical reagent or mechanical system.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
The enhanced heat exchange shell hot type heat exchanger of a kind of ultrasonic wave antiscale, scale removal, its composition comprises: with the housing 1 of clear water import 11, clear water output 12, heat exchanger tube 2 is installed in the described housing, described housing be connected with flat end socket 13 by tube sheet 4, described flat end socket is equipped with blowoff valve 5, described flat end socket is connected with ultrasonic transducer 6, and described ultrasonic transducer is connected with supersonic generator 7.
Embodiment 2:
The enhanced heat exchange shell hot type heat exchanger of above-mentioned ultrasonic wave antiscale, scale removal, described flat end socket has sewage import 8, outlet of sewer 9, described end socket inside is equipped with pass partition 10, and described outlet of sewer place is equipped with described blowoff valve, and baffle plate 3 is housed in the described housing.
Embodiment 3:
The enhanced heat exchange shell hot type heat exchanger of above-mentioned ultrasonic wave antiscale, scale removal, be respectively equipped with municipal sewage import, outlet of sewer on the shell and tube exchanger end socket, have clear water import, clear water output on the housing, municipal sewage and intermediary's fluid reverse circulated in heat exchanger, the tube sheet of municipal sewage entrance location adopts flat, the end socket of intermediary fluid inlet position adopts elliptic, increases the eddy current of sewage.And adopt regularly blowdown of valve at the outlet of sewer place.
Ultrasonic transducer is installed on the flat end socket, faces the circulation pipeline of fluid, and opposite side links to each other with supersonic generator.
A kind of above-mentioned ultrasonic wave antiscale, the enhanced heat exchange shell hot type heat exchanger of scale removal, the points for attention that it uses are:
(1) supersonic generator should be by in the ventilating and cooling place, and generator and transducer should be avoided trickle or bump, guarantee its normal operation;
(2) before the anti-scale removal of acoustic cavitation and reinforced heat exchanger put into operation, make in its pipeline space to be full of fluid first with the heat transmission equipment operation, avoid resonating and fuel factor that transducer produces comes off it; Before heat exchanger is stopped using, the ultrasonic unit of at first stopping transport.At antiscale and reinforced heat exchanger run duration, the heat transmission equipment of must not arbitrarily stopping transport;
(3) during acoustic cavitation prevents that scale removal and reinforced heat exchanger and heat exchanger are simultaneously out of service, can open blowoff valve and emit the sedimentation dirt.
Claims (2)
1. the pipe type heat exchanger with heat exchange shell intensified of a ultrasonic wave antiscale, scale removal, its composition comprises: with the housing of clear water import, clear water output, it is characterized in that: in the described housing heat exchanger tube is installed, described housing be connected with ellipse head by tube sheet, described ellipse head is equipped with blowoff valve, described ellipse head is connected with ultrasonic transducer, and described ultrasonic transducer is connected with supersonic generator.
2. the pipe type heat exchanger with heat exchange shell intensified of ultrasonic wave antiscale according to claim 1, scale removal, it is characterized in that: described ellipse head has sewage import, outlet of sewer, described end socket inside is equipped with pass partition, described outlet of sewer place is equipped with described blowoff valve, in the described housing baffle plate is housed.
