Abstract
The invention discloses a system for automatically cleaning inner pipe walls of a heat exchanger, and provides a technology used for cleaning dirt on the inner pipe walls of the heat exchanger. The system is characterized in that a plurality of opening dirt cleaning rings form dirt cleaning ring groups; two ends of each stainless steel wire for connecting the dirt cleaning ring groups in series are fixed on movable end plates arranged at two ends of the heat exchanger; the movable end plates are connected with a front push arm and a rear push arm at two ends through shafts; the push arms are fixed on a heat exchanger casing through brackets and drive all opening dirt cleaning ring groups by hydraulic pressure or other power to perform reciprocating motion, the push arms on two sides are started periodically to drive the end plates to perform reciprocating motion at a slow and constant speed, and the dirt cleaning ring groups also perform the reciprocating motion in pipes at the slow and constant speed to clean up dirt on the inner pipe wall surfaces. The system for automatically cleaning the inner pipe walls of the heat exchanger is convenient to operate, low in failure rate, small in investment and low in equipment cost and can perform full automatic operation, and further, the friction coefficient of the system is very small, so that the inner pipe walls cannot be damaged.
Description
Technical field:
The present invention is a kind of technology of inner tubal wall dirt being applied to clean pipe shell type heat exchange equipment and evaporator with heat pump, condenser.Structure of the present invention is simple, and operating cost is low, and water resistance is little, failure rate is low, is particularly useful for the occasion with active bio pollution sources.
Background technology:
Along with develop rapidly and the application of heat transmission equipment technology, bring the raising of energy utilization rate.Various development & application in succession that is novel, high-efficiency heat exchanger equipment creates huge economic results in society, but one of major issue still existed so far is exactly inside pipe wall scale problems.The method of current process Tube Sheet of Heat Exchanger encrustation is: one, raising equipment enters water water quality and strengthens filtration system.Two, regular disintegration cleaning equipment tube side inwall.Cleaning mode is then mainly divided into physics to clean and chemical cleaning, and physics cleaning is giant or water cutter and the flushing of hairbrush cleaning cooperation clear water etc.Chemistry cleaning is clear water flushing after weak acid immersion etc.The cleaning of these two kinds of modes just can be carried out after all needing arrestment to run, and all can cause damage in various degree to tube side inwall, greatly reduces effective run time and the service life of equipment.
Summary of the invention:
The present invention is a kind of system adopting the cleaning mode of machinery to solve pipe shell type heat exchange equipment tube side encrustation problem.Native system simplicity of design, quick for installation, easy to operate, failure rate is low, and small investment, equipment cost is low, realizes fully automatic operation, only need set the cycle of operation, without the need to human users.Native system can use when equipment runs, and the coefficient of friction of system own is very little, adopts nonmetallic materials, can not damage inside pipe wall.
The present invention is that the material adopting plastics or micro-elasticity not injure tube wall makes the opening matched with inside pipe wall diameter and to remove contamination ring, to remove contamination multiple ring spaced at equal intervals of removing contamination between ring with a thin sleeve pipe, stainless steel wire will remove contamination ring and thin sleeve pipe interval in center is connected in series, and forms ring group of removing contamination.The stainless steel wire two ends of ring group of serial connection being removed contamination are separately fixed on the movable end plate at heat exchanger two ends, and movable end plate is connected by axle with the forward and backward push arm at two ends, and push arm is fixed on heat exchanger shell place by support, plays a supporting role.Moved back and forth by hydraulic pressure or the forward and backward push arm of other powered, drive whole opening ring group of removing contamination to reciprocatingly move.Regular startup both sides push arm, makes movable end plate do reciprocating low speed and at the uniform velocity moves, and drives ring group of removing contamination in pipe, carry out low speed and moves back and forth evenly, thus the dirt of purge tube inner wall surface.Opening ring external diameter of removing contamination is more bigger than pipe wall internal diameters, and the ring that makes to remove contamination supports swollen on heat exchanger tube inwall all the time, and with inside pipe wall close contact, clean like this inside pipe wall is very thorough, and inside pipe wall can be made to remain at original state.Because ring of removing contamination is opening, swollen dead situation can not be there is.Opening ring of removing contamination all freely is connected with thin sleeve pipe, and each ring of removing contamination is automatically concentric with tube wall, can adapt to the sagging deflections that long tube occurs, also can adapt to high pollution water source.Can according to water quality situation, regular heat exchanger inside pipe wall cleans, and cleans at every turn, several oscillation cycle.
The advantage of the invention:
1, native system can use when heat exchanger runs, and does not need outaged equipment to clear up again.
2, native system self friction coefficient is very little, and opening ring of removing contamination adopts nonmetallic materials, and translational speed is slow, and the working time is short, therefore very little to transducer wall ' s abrasion.
3, simplicity of design of the present invention, quick for installation, easy to operate, the parameters that do not affect original equipment, and small investment, equipment cost is low.
4, the opening of native system ring of removing contamination is very thin, and very little on caliber impact, water resistance increases little.Opening central spacer of removing contamination is arranged in pipe, effectively can eliminate the laminar flow in pipe, improves heat exchange efficiency.
5, operating cost of the present invention is low, and the speed of service is slow, and running time is short, and idle time is long, consumes energy extremely low.
6, water source of the present invention wide adaptability, can adapt to any with serious pollution water source, comprise native sewage water.
7, the present invention adopts hydraulic actuation power, controls simple, easy to operate, also can adopt other mechanical actuation power.And fully automatic operation, as long as set the cycle of operation, without the need to human users.
8, opening of the present invention remove contamination ring with carefully overlap effective stainless steel wire and is connected in series, all freely connect, each ring of removing contamination is automatically concentric with inside pipe wall, can adapt to the sagging deflections of long tube generation.

Detailed description of the invention:
Multiple ring 6 of removing contamination is provided with in the heat exchanger tube 7 of heat exchanger, remove contamination between ring by thin sleeve pipe 5 spaced at equal intervals, to remove contamination ring and thin sleeve pipe interval of center stainless steel wire 4 is connected in series, and forms ring group of removing contamination, installs the ring group of removing contamination of one group of stainless steel wire serial connection in every root heat exchanger tube.
Be connected in series remove contamination ring group the stainless steel wire two ends front movable end plate 3 that is separately fixed at heat exchanger two ends and rear movable end plate 9 on.Forward and backward movable end plate is connected with axle with push arm before two ends 1 and rear push arm 12 respectively, push arm is fixed on heat exchanger shell 8 place respectively by front push arm support 2 and pusher arm support 11, play a supporting role, reciprocatingly moved by hydraulic pressure or the forward and backward push arm of other powered.Regular startup both sides push arm, make end plate do reciprocating low speed uniform motion, thus allow ring group of removing contamination in pipe, carry out low speed moving back and forth at the uniform velocity, the ring that makes to remove contamination does at inside pipe wall and contacts movement slowly, any dirt of purge tube inner wall surface, to reach the object of cleaning inside pipe wall.
