The invention discloses a rotary rubber ball automatic on-line continuous cleaning device and a method. The cleaning device comprises a ball collecting drum, a ball storing drum, a ball charging drum, ball valves and a self-control motor and is characterized in that the ball storing drum comprises a cover plate, an inner drum, a filtering hole plate and an outer drum; the inner drum fixedly sleeve a rotating shaft of the self-control motor and is driven to rotate by the self-control motor; the outer drum sleeves the inner drum; the outer drum is connected with the cover plate; multiple through holes used for storing rubber balls are distributed in the inner drum along the circumference; the filtering hole plate is arranged between the inner drum and a bottom plate of the outer drum; a ball collecting opening and a ball outlet are arranged in the cover plate; the ball outlet is connected with an outlet end of the ball charging drum via a ball valve 3; a water inlet and a water outlet are arranged in the bottom plate; the water outlet is connected with the outlet end of the ball collecting valve via a ball valve 2; a ball collecting filtering screen is arranged in an inlet end of the ball collecting drum; the ball collecting filtering screen is connected with the ball collecting filtering screen via a ball valve 4; and the cleaning device is widely applicable in energy and chemical engineering field.

Description

technical field [0001] The invention relates to a heat exchanger online cleaning device and method, in particular to a rotary rubber ball automatic online continuous cleaning device and method. Background technique [0002] With the progress of human civilization and the improvement of industrial level, the use of energy in modern society is becoming more and more sophisticated, and energy conservation and emission reduction are increasingly called by governments and people of all countries. Shell and tube heat exchangers are widely used in the energy and chemical industry as well as in the HVAC field. Scaling often occurs on the inner wall of the heat exchange tubes of many shell-and-tube heat exchangers that use water as the cooling medium in the tube side. Efficiency is reduced, resulting in a great waste of energy. [0003] The fouling treatment methods on the inner wall of shell and tube heat exchangers are generally divided into two categories: chemical methods and p...

Problems solved by technology

Among them, the rubber balls of the single-circuit system pass through the intermediate ball storage room from the water outlet of the heat exchanger to pause and then enter the water inlet of the heat exchanger or directly into the water inlet of the heat exchanger. This type of system will bring the hot water from the water outlet of the heat exchanger back to the The water inlet of the heat exchanger increases the heat transfer load of the main engine, and the system itself needs to overcome the large pressure difference resistance, which consumes a lot of energy and is very uneconomical

The second type of system is the double-circuit rubber ball cleaning system. The ball collecting circuit and the ball injecting circuit work alternately. The ball only draws cold water from the water inlet of the heat exchanger. This type of system has little effect on the heat transfer load of the main engine, but it requires more power sources (each circuit has a water pump), or more control valves (one pump) The pump switches the working circuit through several three-way valves), resulting in complex structure, high cost, large floor space and required installation space, and not very economical

However, due to the complex internal structure of this invention, there are defects such as bloated volume and large flow channel resistance, which further leads to problems such as high manufacturing cost, large space occupation, and large increase in resistance to the main pipeline system.

And due to its own structural limitations, it cannot adapt to the different spacing of the inlet and outlet pipelines of any shell-and-tube heat exchanger host

[0006] Various existing rubber ball cleaning systems, no matter single-circuit system or double-circuit system, have some or all of the following disadvantages: the device has complex structure, large volume, takes up a large space, is difficult to install on site, and consumes more energy. The resistance of the main pipeline system increases greatly
