Abstract
The invention relates to an automatic anti-scaling system for a tubular heat exchanger. A nylon brush and an automatic cleaning connector are installed at the two ends of a heat exchange tube of the heat exchanger correspondingly. An inlet and an outlet of the low-pressure side of the heat exchanger are connected with a left port and a right port of a reverser correspondingly. A lower port of the reverser is connected with a water outlet of a water pump. A water inlet of the water pump is connected with a water return pipe of the low-pressure side. An upper port of the reverser is connected with a water supply pipe of the low-pressure side. The water flow direction of the low-pressure side in the heat exchanger is changed through the reverser; water flow drives the nylon brush to move back and forth in the heat exchange tube, iron rust and sediment which are newly gathered are discharged out of the heat exchanger, and thus the purpose of automatic cleaning is achieved. The automatic anti-scaling system for the tubular heat exchanger is low in investment cost, stable in performance and good in effect.
Description
Technical field
The present invention relates to the automatic good antiscale property system of a kind of pipe heat exchanger, be specially a kind of employing at the in-built nylon bruss of heat exchanger tube, by changing the direction of a stream of water to reach the automatic good antiscale property system of pipe heat exchanger of cleaning heat exchanger tube automatically.
Background technology
Heat exchanger extensive use in refrigeration, ensures that the heat exchange efficiency of heat exchanger is more and more important, but in actual applications, the heat exchange efficiency of heat exchanger declines very terrible, will be mainly that water quality is very poor, cause heat exchanger tube fouling, affect heat exchange efficiency, and then cause refrigeration.
At present, heat exchanger heat-exchanging tube cleaning is generally adopted in two ways, and a kind of manual cleaning, another kind is Chemical cleaning.Manual cleaning: need to pull down two pipelines and heat exchanger two ends end cap that are connected with heat exchanger tube pass, then a hairbrush is put at heat exchanger tube, hairbrush two steel wire connects, two people pull back at heat exchanger tube two, use high pressure water flushing afterwards, and such one one is cleaned heat exchanger tube, a heat exchanger has more than 100 200 heat exchanger tubes, such one one cleaning, very time-consuming, also can only clean when heat exchanger is out of service.Chemical cleaning: need to pull down two pipelines be connected with heat exchanger tube pass, then heat exchanger two pipeline opening load onto two cover plates, each cover plate there is a little flexible pipe, a little flexible pipe is connected with bucket, the little flexible pipe of another root is connected with little immersible pump, little immersible pump is placed in bucket, chemical solvent is injected in bucket, start immersible pump, first in heat exchanger, fill chemical solvent, stop to bucket injectionization solvent after filling chemical solvent, immersible pump continues to run, chemical solvent is at bucket, immersible pump, circulate between heat exchanger, chemical solvent dissolves the fouling in heat exchanger tube, residue takes heat exchanger tube out of by the chemical solvent of flowing, reach the object of cleaning heat exchanger tube, Chemical cleaning also just can will be carried out when heat exchanger is out of service.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide a kind of novel heat exchanger tube cleaning method.
The implementation of object of the present invention is: at heat exchanger heat-exchanging tube 4 two ends dress nylon bruss 1 and automatic cleaning joint 2; Changed the water (flow) direction of low-pressure side in heat exchanger by commutator 12,13, current drive nylon bruss 1 to move back and forth in heat exchanger tube 4, and the iron rust newly assembled and sediment are discharged heat exchanger 5, to reach the object of cleaning automatically.
The present invention and manual cleaning are compared with Chemical cleaning has following features:
A, manual cleaning and Chemical cleaning all need could clean when stopping heat exchanger running, and the present invention does not need to shut down, and does not affect whole system to run;
B, manual cleaning and Chemical cleaning all need expense, and the present invention does not need expense, only need install hairbrush in heat exchanger tube, and pipeline increases a steering gear.
Accompanying drawing explanation
Accompanying drawing Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to accompanying drawing, the present invention, by nylon bruss 1, cleans joint 2 automatically, tube sheet 3, heat exchanger tube 4, heat exchanger 5, heat exchanger high-voltage side delivery port 6, heat exchanger high-voltage side water inlet 7, heat exchanger low pressure entery and delivery port 8, low-pressure side feed pipe 9, low-pressure side return pipe 10, water pump 11, commutator 12, commutator 13 and related valve form.
When the present invention works, water pump 11 starts, and water enters heat exchanger 5 by commutator 12, and the nylon bruss 1 in bottom heat exchanger tube 4 in heat exchanger 5 is rushed at the left side by current, the nylon bruss 1 in heat exchanger 5 internal upper part heat exchanger tube 4 is rushed at the right; Commutator 12 forwards commutator 13 to, low-pressure side current in heat exchanger 5 are reverse, nylon bruss 1 in bottom heat exchanger tube 4 in heat exchanger 5 is rushed at the right by current, nylon bruss 1 in heat exchanger 5 internal upper part heat exchanger tube 4 is rushed at the left side, commutator 12 and commutator 13 constantly convert, and nylon bruss is under the effect of waterpower, and pass through motion, the iron rust newly assembled and sediment are discharged heat exchanger 5, to reach the object of cleaning automatically.
Claims (2)
1. the automatic good antiscale property system of pipe heat exchanger, it is characterized in that heat exchanger heat-exchanging tube two ends dress nylon bruss and automatically clean joint, heat exchanger low-pressure side is imported and exported and is connected with mouth about commutator, commutator end opening connects with pump outlet, pump intake connects with low-pressure side return pipe, and commutator is suitable for reading to connect with low-pressure side feed pipe.
2. each pipeline to be pretended closing valve and configuration component.
