Description

[0001] The invention relates to the technical field of cleaning of industrial equipment, in particular to an online corrosion monitoring device for chemical cleaning of equipment. Background Art

[0002] In many industries such as chemical industry, food processing, and pharmaceutical industry, reactors are widely used as key equipment in the mixing, reaction, and processing of various materials. However, during long-term use, the inside of the reactor is very easy to form dirt due to material residues, chemical reaction product adhesion, etc. These dirt will not only reduce the heat transfer efficiency of the reactor, affect the reaction rate and product quality, but also become a breeding ground for microorganisms, posing a threat to product safety. Therefore, regular chemical cleaning of the reactor has become a necessary measure to ensure its normal operation and product quality.

[0015] Working principle: By installing a support block on the upper surface of the support column, when the probe detects that the inside of the support column is strongly acidic, the probe will detect a signal and transmit the signal to the inside of the control center. The control center analyzes the signal and controls the water pump to extract alkaline liquid from the inside of the liquid tank. The alkaline liquid is sprayed from the inside of the nozzle through a hose to neutralize the strong acid inside the support column. At the same time, when the nozzle measures the data of the degree of corrosion, if the data obtained exceeds the standard value, the monitoring device releases a smaller amount of agent and reduces the amount of agent, thereby effectively preventing the inner wall of the support column from being thinned and perforated due to excessive action of the cleaning agent, ensuring the structural integrity and safety of the equipment, avoiding excessive corrosion of the equipment due to excessive agents, and greatly extending the service life of the equipment; By installing a support block on the upper surface of the support column, when the probe detects that the inside of the support column is strongly acidic, the probe will detect a signal and transmit the signal to the inside of the control center.

The rotation of the motor drives the connecting rod 1 to rotate. Under the action of the connecting rod 1, the connecting rod 2 drives the shaking rod to rotate and swing on the lower outer wall of the fixed column. The swing of the shaking rod drives the nozzle to swing, so that the spraying amount and spraying intensity of the cleaning liquid at different positions can be more balanced, preventing the situation where local cleaning is excessive and other parts are not cleaned thoroughly, improving the overall cleaning quality, and making the cleanliness of the equipment surface more consistent; By manually turning the knob, the rotation of the knob will drive the rotating piece to rotate, and the rotation of the rotating piece will drive the sliding column to move up and down. When the sliding column moves up and down, it will drive the connecting column and the connecting plate to move up and down. The up and down movement of the connecting plate will drive the probe to move up and down, so that it can more conveniently adapt to the installation space and position requirements of the equipment. When the space around the equipment is narrow, the probe can be retracted first to facilitate the installation and fixation of the device. After the installation is completed, the probe can be extended to the appropriate position for monitoring. When maintaining the equipment, the probe can also be retracted to facilitate the inspection and replacement of components of the monitoring device, reducing the difficulty and cost of installation and maintenance.

The present invention transmits the detected signal to the control center through the probe, and the control center analyzes and controls the extraction amount of the water pump, thereby effectively preventing the inner wall of the reactor body from being thinned and perforated due to excessive action of the cleaning agent, ensuring the structural integrity and safety of the equipment, avoiding excessive corrosion of the equipment due to excessive agents, and greatly extending the service life of the equipment.

[0017] 2. The present invention drives the motor to rotate through the control center, and the motor drives the nozzle to swing, so that the spraying amount and spraying intensity of the cleaning liquid at different positions can be more balanced, preventing excessive local cleaning and incomplete cleaning of other parts, improving the overall cleaning quality, and making the cleanliness of the equipment surface more consistent.

[0022] Please see attached Figure 1 The embodiment of the present invention provides an online corrosion monitoring device for chemical cleaning of equipment, comprising: Detection module, used to collect corrosion data of equipment; A data transmission module, which converts the corrosion data collected by the detection module into digital signals and transmits them to the data analysis and processing module; The data processing and analysis module is used to compare the preset corrosion standard value, which is ≤0.5mm / a, and judge whether the data collected by the detection module exceeds the corrosion standard value. If it exceeds the corrosion standard value, the control output module will reduce the output of liquid. If it does not exceed the corrosion standard value, the control output module will output liquid normally. The control output module controls the displacement of the released agent according to the judgment result of the data processing and analysis module, and is used to control the displacement of the released agent; The detection module includes a probe 23, and the probe 23 is an eddy current probe.

[0023] Specifically, the core component of the detection module is the eddy current probe 23, which works based on the principle of electromagnetic induction. When the probe 23 is close to the surface of the device to be detected, an alternating magnetic field will be generated on the surface of the device. If there is corrosion on the surface of the device, the electrical conductivity and magnetic permeability of the device will change, thereby causing changes in eddy currents, and further detecting the degree of corrosion. The eddy current probe 23 detects the corrosion on the surface of the device, which belongs to the prior art. The eddy current probe 23 can be purchased directly on the market and is a well-known technology for those skilled in the art. The eddy current probe 23 is used to detect the corrosion information on the surface of the device. The data transmission module converts the corrosion information collected by the detection module into an analog signal form suitable for transmission on the medium, so that the signal can be stably transmitted in the transmission line, reducing signal attenuation and interference. In wireless transmission, the digital signal is modulated onto a carrier of a specific frequency. The data processing and analysis module converts the received data into a unified internal data format, and transmits the analyzed data to the interior of the control output module. The control output module is used to control the dosage of the liquid sprayed.

The data preprocessing unit is used to smooth the received data and remove noise and fluctuations in the data.
