Embodiment 1

[0024] The present invention is a device capable of realizing stable self-cleaning of heat exchangers, comprising a heat exchanger 1, an air compressor 6, a pulse controller 5,

[0025] The input end and the output end of the heat exchanger 1 are respectively provided with an input end flexible joint 3 and an output end flexible joint 2, and the input end flexible joint 3 communicates with the main pipeline 8,

[0026] The main pipeline 8 is provided with a solenoid valve 7, and the main pipeline 8 is provided with an air blowing pipeline 4 communicating with it, and the air blowing pipeline 4 communicates with the air compressor 6 through the pulse controller 5, The air blowing pipeline 4 is located between the flexible joint 3 at the input end and the electromagnetic valve 7,

[0027] The main pipe 8 is provided with a water hammer eliminator 9 located at the front end of the solenoid valve 7 .

[0028] The main pipeline 8 is provided with a manual shut-off valve located at...

Embodiment 2

[0030] The present invention also provides a method for using a stable self-cleaning device for a heat exchanger, which includes the following steps:

[0031] Step 1: parameter setting, the pulse controller 5 is connected to the air bag on the air compressor 6 with a rated pressure of 0.8 MPa, and the pulse controller 5 is set to a short blow with a pulse width of 0.5 seconds every ten minutes and every ten minutes A long blow with a pulse width of 2 seconds once an hour;

[0032] Step 2: blowing and cleaning, while the solenoid valve 7 is closed, the pulse controller 5 is turned on to blow gas into the heat exchanger 1 through the air blowing pipe 4 and the main pipe 8, so that The electromagnetic valve 7 is used to block and prevent the reverse blowing of gas;

[0033] Step 3: Resume production. After the blowing and cleaning in Step 2, close the pulse controller 5 and open the solenoid valve 7 to carry out normal production.

[0034] In the second step, the blowing gas ad...

Abstract

The invention discloses a device capable of achieving stable self-cleaning of a heat exchanger and a using method thereof.The device comprises the heat exchanger, an air compressor and a pulse controller, the two ends of the heat exchanger are provided with an input end flexible connector and an output end flexible connector respectively, the input end flexible connector communicates with a main pipeline, the main pipeline is provided with an electromagnetic valve, and the main pipeline is provided with an air blowing pipeline; the air blowing pipeline is communicated with the air compressor through the pulse controller and located between the input end flexible connector and the electromagnetic valve, and a water hammer eliminator located at the front end of the electromagnetic valve is arranged on the main pipeline. Compared with the original process method, the treatment capacity per hour is 8 tons, but the treatment capacity of the original process is reduced to 7.6 tons per hour after the method is applied for one month, and the phenomenon of scaling inside the equipment is more serious as time goes on until the equipment is shut down for overhaul and maintenance. However, the treatment capacity of the existing process method is still 8 tons per hour, and the cleaning effect is remarkable, continuous and effective.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil temperature measuring equipment, and in particular relates to a device capable of realizing stable self-cleaning of a heat exchanger and a use method thereof. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. At present, scaling is common in heat exchangers, which leads to a huge expenditure of financial and material resources every year to remove scaling. Severe scaling will also affect production safety. [0003] Traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water methods, chemical cleaning (pickling) methods, etc., these methods will have many disadvantages when cleaning the heat exchanger: [0004] If the scale and other deposits cannot be completely removed, the acid will corrode the equipment and form holes, and the residual ...
