Description
Technical field
The utility model relates to a kind of cleaning device, particularly relates to a kind of company and moves back stove heat exchanger on-line cleaning system.
Background technology
CAL connects and to move back the exchange capability of heat of stove heat exchanger along with the prolongation of service time, and the exchange capability of heat of heat exchanger descends gradually, influences the unit production capacity.It is old heat exchanger to be carried out off-line clean that heat exchanger cleans conventional method, consumes substantial contribution and spare part, has a strong impact on the unit operation rate.Even move back the stove heat exchanger structure from CAL, the heat exchanger dismounting is considered in the installation site, and heat exchanger damage phenomenon takes place in the transportation easily, and it is extremely important to develop the heat exchanger on-line cleaning in this case.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and stove heat exchanger on-line cleaning system is moved back by easy to operate company.
In order to address the above problem, the utility model by the following technical solutions:
Connect and move back stove heat exchanger on-line cleaning system, comprise heat exchanger outlet conduit, heat exchanger inlet channel, input duct, fluid pipeline, relief pipeline, circulating pump and water tank; Input duct one end is connected with the heat exchanger outlet conduit, and an end is connected with water tank; Fluid pipeline one end is connected with the heat exchanger inlet channel, and an end is connected with water tank 7; Circulating pump is installed on the input duct, is respectively equipped with stop valve on the input duct of circulating pump both sides, the fluid pipeline; Relief pipeline one end is connected with water tank, and an end is connected between circulating pump and the close stop valve of heat exchanger inlet channel one side; Safety valve and Pressure gauge are installed on the relief pipeline.
Compared with prior art, the beneficial effects of the utility model are:
Utilize the utility model can realize the on-line cleaning of heat exchanger, greatly reduced taking and downtime of equipment funds, improved the unit operation rate, for enterprise has saved a large amount of maintenance costs.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Connect and move back stove heat exchanger on-line cleaning system, as shown in Figure 1, comprise heat exchanger outlet conduit 2, heat exchanger inlet channel 1, input duct 9, fluid pipeline 6, relief pipeline 8, circulating pump 5 and water tank 7, water tank is equipped with cleaning fluid for 7 li; Input duct 9 one ends are connected with heat exchanger outlet conduit 2, and an end is connected with water tank 7; Fluid pipeline 6 one ends are connected with heat exchanger inlet channel 1, and an end is connected with water tank 7; Circulating pump 5 is installed on the input duct 9, is respectively equipped with stop valve 3 on the input duct 9 of circulating pump 5 both sides, the fluid pipeline 6; Relief pipeline 8 one ends are connected with water tank 7, and an end is connected between circulating pump 5 and the close stop valve 3 of heat exchanger inlet channel 2 one sides; Safety valve 10 and Pressure gauge 11 are installed on the relief pipeline 8.
When cleaning the heat exchanger inwall, clean by the reverse of former flow of cooling water direction.Close the inlet and outlet pipe lines of original heat exchanger 4, open stop valve 3, start circulating pump 5, adjust the opening degree size of stop valve 10, the pressure of cleaning fluid is set at 1.5bar; Pressure gauge 11 shows the pressure of cleaning fluid, makes cleaning fluid circulate between input duct 9, heat exchanger 4, fluid pipeline 6 and water tank 7, reaches the purpose of on-line cleaning heat exchanger 4, thereby guarantees the normal operation of whole purging system.
