Abstract

The invention particularly discloses a pulsation device of a heat exchanger for strengthened descaling, and belongs to the technical field of energy source. The pulse device of the heat exchanger can solve the problem of pipeline scaling and low heat exchanging efficiency during the process of heat exchange between non-clean water and clean water. The pulse device of the heat exchanger is provided with two water inlets and two water outlets; the two water inlets are flow in from the tangential direction so as to rotate a moving disk; when the water outlet of the moving disk is rotated to a water storage space at one face of a fixing disk, water cannot flow through the other one water storage space; two water storage spaces of the fixing disk are in hard sealing connection; the continuous rotation of the moving disk realizes the water division, and further the pulsation of water flow is realized; two water outlets are respectively connected with the water inlets of the heat exchanger, so that the heat exchanger is smoothly and efficiently worked. The pulsation device of the heat exchanger for strengthened descaling is applied to scaling prevention and descaling of the heat exchanger pipeline.

Description

A kind of palsating equipment of heat exchanger reinforced scavenging
Technical field
The present invention relates to a kind of palsating equipment of heat exchanger reinforced scavenging, belong to energy technology field.
Background technology
Source of sewage or earth surface water source are all the one kind at water source, compare its big, Yi that is mainly characterized by impurity content of underground water Form dirt in heat exchange wall and pipeline, not only accelerate wall erosion, so that heat transmission equipment service life is substantially reduced, also can affect Heat exchange efficiency, increases the flow resistance of fluid.Therefore, antiscale, scale removal are the important technologies carrying out heat exchange using non-clean water.
Abundant low grade heat energy is contained in the non-clean water such as sewage, surface water, can be low-grade by these using heat exchanger Heat energy extracts as building heating air-conditioner, has huge energy-saving and environmental protection and economic worth, its energy-conservation extreme magnitude.Press China's existing quantity of wastewater effluent measuring and calculating, develops sewage Lowlevel thermal energy, can be a lot of City Building heat supplying air conditionings, it is opened Send out that application prospect is boundless, be one of effective way that building energy conservation reduces discharging.
Current anti-descalling technique mainly has following two forms, and all there is certain deficiency:
One kind is glueballs on-line cleaning technology, such as the patent No. 201320209861.1, notification number cn203240955u, title For the patent of invention of " for the ball cleaning apparatus of heat pump ", it be by glueballs in flow process with the rubbing of heat exchange inside pipe wall Wiping acts on, and reaches and exchanges, with glueballs, the purpose that heat pipe inner wall is carried out, but its using effect in the case that water quality is poor Undesirable, not only ball collecting rate is low, and secondary filter and ball screen equally exist fouling and the problem of corrosion.
Another kind is that pipe is inserted into thing (as rotation tie etc.) on-line cleaning technology, such as the patent No. 200720154258.2, Notification number cn201034457y, the patent of invention technology of entitled " Automatic descaling enhanced heat exchanger of helical coils ", it be according to Effect by fluid rotates or vibration reaches the purpose of anti-scale removal, but for heat exchange area is big, heat-transfer pipe quantity is many and long Non-clean water- to-water heat exchanger, its mechanical technology is excessively complicated, and initial cost is big, and the non-clean water more than impurity content easily causes The blocking of insert, corrosion and damage.
Content of the invention
The purpose of the present invention is exactly the problems referred to above in order to solve existing apparatus presence, provides a kind of reinforced scavenging type heat exchange Device, it can realize the pulsation of current, the problem of the tube wall incrustation in the non-clean water of effectively solving and clean water heat transfer process.
