Double-effect evaporators, multi-effect evaporators, falling film evaporators, forced circulation evaporators, and similar equipment are widely used in chemical, pharmaceutical, food, new energy, and environmental protection industries. Over extended operation, evaporator tubes tend to accumulate material deposits, coke, crystals, scale, and other hard fouling, leading to reduced evaporation efficiency, increased energy consumption, and in severe cases, complete tube bundle blockage.
Anhui Kuaitong Pipeline Cleaning Technology Co., Ltd. specializes in the R&D and manufacturing of industrial pipeline cleaning equipment. Addressing various evaporator blockage conditions, we have developed the KT-307 Industrial Pipe Unclogging Machine. Using a mechanical rotary unclogging method combined with flexible shafts, high-strength alloy steel drill bits, and an intelligent control system, the KT-307 provides industrial enterprises with a more efficient and safer solution for evaporator tube bundle unclogging.
1. Common Evaporator Blockage Conditions
Evaporator blockage is not limited to coking alone; the type of fouling varies across different industries. Based on years of on-site experience, Anhui Kuaitong categorizes evaporator blockages into the following main types:
Material Deposition – This is the most common blockage type. In chemical, food, and pharmaceutical industries, process media adhere to the inner walls of evaporator tubes over time, gradually accumulating and eventually causing partial or complete blockage.
Coking – Under high-temperature conditions, organic materials continuously coke and carbonize, forming hard layers on tube walls that are difficult to remove with conventional flushing methods.
Crystallization – Salts and other chemical media precipitate crystals during the concentration process. Over long-term operation, these crystals form hard layers that reduce evaporation efficiency.
Scale Deposition – Minerals in circulating cooling water systems continuously deposit inside evaporator tubes. If left uncleaned, scale buildup impairs heat transfer capacity.
Mixed Fouling – In actual field conditions, most evaporator blockages are composite fouling consisting of multiple deposit types. Different working conditions require different drill bit specifications and cleaning strategies.
2. How to Handle Evaporator Blockage
Depending on the severity of blockage, common treatment methods include:
Chemical cleaning
High-pressure water cleaning
Mechanical unclogging
For severe material deposition, coking, crystallization, and hard scale, mechanical unclogging generally offers better adaptability. The KT-307 uses high-strength alloy steel drill bits to progressively break down blockages while a water supply system flushes out crushed debris, significantly improving cleaning efficiency.
3. How the KT-307 Performs Evaporator Unclogging
The KT-307 employs a mechanical rotary unclogging principle. A 5500W power drive unit rotates a flexible transmission shaft at high speed, with a high-strength alloy steel drill bit mounted at the front end. During operation, the drill bit enters the evaporator tube and progressively breaks down the blockage. Simultaneously, the water supply system continuously delivers water through the shaft, flushing out crushed debris while cooling the drill bit and shaft. The equipment supports both dry unclogging and water-assisted cleaning, allowing flexible selection based on different blockage conditions.
4. Core Advantages of the KT-307
Wide Applicable Tube Diameter Range – The KT-307 accommodates industrial tube bundle equipment from Φ6.35 mm to 800 mm. For different evaporator sizes, flexible shafts of various lengths and drill bits of different specifications can be configured.
High-Strength Alloy Steel Drill Bits – The KT-307 is equipped with multiple specifications of high-strength alloy steel drill bits. They can be flexibly matched to different blockage types, making the equipment suitable for material deposition, coking, crystallization, and hard scale. With proper operation and correct selection, the drill bits achieve both effective unclogging and good tube-wall protection.
Intelligent Torque Adjustment System – During operation, the equipment automatically adjusts output torque based on blockage resistance, reducing instantaneous overload and improving operational stability.
Adaptive Shaft Protection Technology – The KT-307 features a self-developed adaptive shaft protection system that automatically adjusts power output based on load variations, effectively reducing wear on the flexible shaft and related components, thereby lowering maintenance costs.
0–4000 rpm Stepless Speed Control – The equipment supports stepless speed adjustment from 0 to 4000 rpm. Operators can flexibly adjust the rotational speed based on evaporator tube diameter, blockage severity, and fouling type, making the equipment adaptable to a wider range of working conditions.
Manual + Wireless Remote Dual Control – The KT-307 supports both on-site manual control and wireless remote control. For large evaporators or space-constrained environments, operators can flexibly switch between control modes to improve work efficiency.
Split-Type Structural Design – The KT-307 features a separate power unit and control cabinet. In product development, Anhui Kuaitong identified that vibration from continuous operation of the power unit can affect control system stability. The split-type design reduces vibration transfer to the control cabinet, protects electronic components, extends control cabinet service life, and improves long-term operational reliability.
Parameter Memory and Voice Guidance – The equipment supports one-key recall of operating parameters and voice-prompted guidance. For repetitive jobs, historical parameters can be quickly loaded, improving efficiency and reducing setup time.
5. KT-307 Evaporator Unclogging Workflow
To improve operational efficiency, Anhui Kuaitong recommends following this procedure:
Site Survey – Confirm evaporator model, tube diameter, tube length, and blockage condition.
Equipment Configuration – Select appropriate shaft and drill bit specifications based on site conditions.
Equipment Installation – Connect the power unit, control cabinet, flexible shaft, and water supply system.
Parameter Adjustment – Set operating speed and output parameters according to blockage severity.
Begin Unclogging – The drill bit progressively enters the tube to break down blockages, assisted by water flushing.
Inspection and Acceptance – After completion, check tube bundle patency and establish a follow-up maintenance plan based on equipment operating conditions.
