Abstract
Description
The present invention relates to a scale removing system and a temperature control system for a heat exchanger, and more particularly, to a system and method for controlling scaling and temperature control of a heat exchanger by controlling the flow of cooling water, And more particularly to a scale removal and temperature control system for a heat exchanger.
Generally, the water used is mainly divided into sewage water, industrial (industrial) water, ground water, and the like. On the other hand, mineral and gaseous elements such as various metal elements and minerals are dissolved in the water for use (hereinafter referred to as 'cooling water'), and if these substances are not appropriately treated, the above- Is a source for generating various bacteria and microorganisms by generating rust and scale in piping and water tanks (including dipping resin).
Particularly, in case of using a heat exchanger, a temperature controller and a raw material feeder (hereinafter referred to as "peripheral equipment") of an injection machine for a long time, the cooling water moves to generate rust and scale inside the pipes and peripheral devices, There is a problem that its own functions such as peripheral devices are lost or the efficiency is remarkably reduced.
The "device for removing foreign substances such as rust and scale in a pipe" which is originally filed by the applicant is installed in piping or peripheral equipment for supplying and circulating water to the peripheral devices and simultaneously discharging water and compressed air, It has the effect of eliminating or suppressing the generation.
In addition, the air injection device installed in the mold, which is installed in the mold, is provided with an air injection device in the mold, and the compressed air moves along with the water to the cooling hole side to generate vortices and turbulence, It has an effect of effectively removing scale and foreign matter.
As described above, the above-mentioned conventional patents have a structure in which water and compressed air are injected into a mold, a heat exchanger, a peripheral device and circulated while effectively removing scale components and foreign substances formed on the entrance side of a mold, a peripheral device, And peripheral devices have a problem in that the supply pressure of water and compressed air becomes weak and scale components and foreign substances can not be sufficiently removed. Particularly, when a line through which water such as a mold and a peripheral device is circulated is long, clogging of a mold, a heat exchanger, a peripheral device and the like is rapidly progressed.
In order to solve the above problems, an electric ball valve for regulating the flow of cooling water is installed to selectively control the heat exchange of the heat exchanger in the winter season and the summer season, and to reduce the back pressure applied to the heat exchanger and the return pipe, The present invention provides a scale removal and temperature control system for a heat exchanger that maximizes the operation of the heat exchanger and effectively prevents scale removal or stenosis in the heat exchanger.
In accordance with the present invention, there is provided a system for removing scale and temperature of a heat exchanger comprising a water tank, a heat exchanger, a supply pipe and a return pipe installed between the water tank and the heat exchanger, Way valve for switching the direction of the compressed air, an electric ball valve installed in the return pipe for controlling the flow rate of the cooling water, and a compressed air valve installed in the supply pipe on the rear side of the four- A control unit for controlling the operation of the four-way valve to guide the cooling water and the compressed air supplied from the heat exchanger in the forward and reverse directions, and a first communicating pipe provided in the supply pipe and the return pipe, A three-way valve installed in the first communicating pipe and the supply pipe, a cooling water suction induction part provided in the first communicating pipe, a cooling water suction inducing part, And a second communicating tube formed in the heat exchanger.
Therefore, the scale removal and temperature control system of the heat exchanger of the present invention controls the flow rate of the cooling water according to the temperature change of the cooling water such as diagonal and seasons by the electric ball valve to realize the temperature of the operating oil heat exchanged in the heat exchanger more stably And the back pressure applied to the heat exchanger, the water supply pipe and the return pipe is reduced to maximize the operation of the air injection device, thereby effectively preventing scale removal or stenosis in the heat exchanger.
