Description

Full-automatic tube brush on-line cleaning system
Technical field
The present invention relates to heat exchanger cleaning equipment technical field, be related specifically to a kind of full-automatic tube brush on-line cleaning system.
Background technology
Heat exchanger is one of chemical industry, the widely used equipment of dynamic field, and its function is to make heat be delivered to cold flow body from hot fluid.Circulating cooling water-to-water heat exchanger be modern industry production line cooling system in indispensable equipment.
Fouling of heat exchangers is a kind of universal phenomenon, is also urgent problem simultaneously.In the design phase, during due to design, choose the dirt resistance lower than actual dirt, after heat exchanger actual motion a period of time, occurring that heat exchange is not enough, if increasing new heat exchanger to carry out parallel running, then can increase investment.
Fouling of heat exchangers can increase heat transfer resistance, reduces the heat transfer efficiency of heat exchanger, causes unnecessary energy resource consumption;The formation of schmutzband can make fluid resistance in heat exchanger increase, and overall heat-transfer coefficient can decline, and when it drops to after to a certain degree, heat exchanger can not meet industrial demand;Accumulation of dirt also can cause hot-spot to cause that mechanical performance declines, and local corrosion is even bored a hole, the safe operation of serious threat equipment.
Therefore, heat exchanger is due to the often cleaning of fouling needs.There is the problem that device is complicated and cleaning performance is not good in a lot of physics, chemistry on-line cleaning method now, such as, physical cleaning effect significantly but generally cannot realize on-line cleaning, metal surface can be produced certain loss simultaneously, and Chemical cleaning easily realizes on-line cleaning but scavenging period is long and cleaning performance is general.Therefore, it is generally adopted at present and takes the mode that heat exchanger off-line cleans apart, but this results in regular stop work and production, add unnecessary labor intensity, maintenance cost and production suspension induced losses is caused to significantly improve, and, current cleaning is just for tube bank inwall or heat exchanger tube pass, and heat exchanger connected component does not process, heat exchanger heat transfer effect so can be affected.
Current tube brush rinser many employings four-way change-over valve carries out water route commutation, but conventional four-way change-over valve is rotary, realizes the commutation in water route by rotating different angles.Adopting this four-way change-over valve, it is necessary to extra complicated control system, the anglec of rotation is accurately controlled, cost is higher, complicated structure, and is not easy maintenance and changes.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art; there is provided one can be carried out by heat exchanger in the non-stop-machine situation of handpiece Water Chilling Units; prevent heat exchanger tube inwall dirty; use simpler reliable water route reversing arrangement simultaneously; thus improving the heat exchange efficiency of unit, reduce the full-automatic tube brush on-line cleaning system of equipment cost.
To achieve these goals, the present invention is by the following technical solutions: full-automatic tube brush on-line cleaning system, this system is arranged in the water-flow circuit of cooling tower, cooling water pump and heat exchanger composition, include nylon bruss, brush basket, four-way change-over valve and control system, it is characterized in that, described brush basket is loaded on the heat exchanger tube termination of heat exchanger, and connects water route and heat exchanger tube, and brush basket is built with movable nylon brush;Described four-way change-over valve is installed on water route, control the two-way flow of heat exchange in-pipe flow, four-way change-over valve includes tetra-interfaces of ABCD, wherein A interface, B interface correspondence water route water inlet and outlet, C interface, the water inlet of D interface correspondence heat exchanger tube and outlet, four-way change-over valve is internally provided with lateral partitions, and inner space is divided into upper and lower two parts, and A interface and B interface are separated by upper segment space by vertical baffle;The described lateral partitions left side is arranged with two hole corresponding A interfaces of M, N, the right is arranged with two hole correspondence B interface of X, Y, four-way change-over valve is provided with two pistons in left and right, left piston correspondence M, two holes of N, control the two hole only one of which and be in opening, right piston correspondence X, two holes of Y, control the two hole also only one of which and be in opening;Described lateral partitions is arranged below vertical flow distribution plate, the plane of flow distribution plate and the plane of vertical baffle are vertically arranged, flow distribution plate is positioned at lateral partitions lower surface center, M hole and X hole are divided into one group, N hole and Y hole are divided into another group, the water route of two groups is isolated from one another opens, and C interface and D interface are also divided into front and back two parts by flow distribution plate simultaneously;Positive and negative both sides bottom described flow distribution plate are each provided with one group of baffle plate, and baffle plate is L shape, and one group is blocked front C interface not shelves front D interface, and another group blocks back side D interface not block back face C interface;This group water route of M hole and X hole jointly connects this group water route of front D interface, N hole and Y hole and jointly connects back side C interface.
In such scheme, described nylon bruss is guide type brushhead designs, include brush and brush body, wherein brush is placed arrow type structure, brush body connects brush, and brush body is sped structure, and brush body periphery is provided with bristle, ensure the formula that the is rotationally advancing work of brush, thoroughly clean efficient corrugated tubing and light pipe type heat exchange inwall.
In such scheme, the piston of described four-way change-over valve is circumscribed with control system, controls the movement travel of piston.
Principles of the invention is in that:
Changing conventional rotary four-way change-over valve into piston type, owing to piston only has two grades, stroke only has two limit positions, therefore greatly reduces the complexity of control, it is only necessary to promote back and forth between two limit positions by external force.The motion of piston makes M and N that a hole can only be had to open, and in like manner X and Y also can only have a hole to open.Owing to A interface is fixing water route water inlet, B interface is fixing water route outlet, therefore realizes water route commutation, it is only necessary to allows water exchange from C interface and D interface and flows out and flow into.
When M hole and Y hole are opened, when N hole and X bore closure, current flow into from A interface, through M hole, flow out from front D interface, after circulation, flow into from back side C interface, then pass through Y hole, flow out from B interface.
When N hole and X hole are opened, when M hole and Y bore closure, current flow into from A interface, through N hole, flow out from back side C interface, after circulation, flow into from front D interface, then pass through X hole, flow out from B interface.
Due to the fact that and have employed technique scheme, have the advantages that
Can being carried out by heat exchanger in the non-stop-machine situation of handpiece Water Chilling Units, it is prevented that heat exchanger tube inwall dirty, use simpler reliable water route reversing arrangement simultaneously, thus improving the heat exchange efficiency of unit, reducing equipment cost.
