Abstract
The utility model relates to cold exchange equipment used in industries such as oil refining, chemical engineering, electric power, textile, paper making and the like, in particular to an on-line forced back flushing device for a cooler, which comprises a cooler cooling pipeline, wherein the cooler cooling pipeline is arranged on the cooler and consists of a cooling water inlet pipeline and a cooling water outlet pipeline, a cleaning water discharge pipeline is arranged on the cooling water inlet pipeline, in addition, the cooling water outlet pipeline and the cleaning water discharge pipeline form a cooler cleaning pipeline, and corresponding pipeline control valves are respectively arranged on the cooling water inlet pipeline, the cooling water outlet pipeline and the cleaning water discharge pipeline. The on-line forced back flushing device for the cooler has the advantages that the equipment investment is low, the ground is not occupied, and the operation is simple and convenient.
Description
Technical field
The utility model relates to the cold exchange device that industries such as oil refining, chemical industry, electric power, weaving, papermaking are used, and refers in particular to the online pressure back purge system of a kind of cooler.
Background technology
In the production process of industries such as oil refining, chemical industry, thermoelectricity and papermaking, the heat transmission equipment scale problems is one of difficult problem of equipment control and maintenance always, and is totally unfavorable for the long period safe operation of device.Fouling makes the equipment heat transfer efficiency seriously descend, and energy consumption raises, and product quality reduces, and then has influence on the even running of device, also can cause equipment to stop up when fouling is serious, causes device stop work and production.At present, 3 kinds of methods of the scale removal of oil refining and chemical industry cooler and the main employing of cleaning, the one, in circulation, throw in water stabilization and antisludging agent (abbreviation medicament delivery), the 2nd, when device is stopped work, carry out chemistry or machinery and clean (comprising that giant cleans), the 3rd, cooler glueballs on-line cleaning technology.All there is certain problem in above method in most application scenarios.Because circulation is bigger, leak easily when circulation is carried out medicament delivery, and all kinds of impurity enters system and cause water quality deterioration, medicament delivery is difficult to control, and effect is generally undesirable.Stop work to clean and to solve in the equipment running process, and increased the unnecessary cost of overhaul, influenced the normal operation cycle of equipment because fouling causes problems such as decline of equipment heat transfer efficiency and equipment capacity reduction.Though cooler glueballs on-line cleaning technology also is to utilize the method for circulation self pressure as power, need to use complete set of equipments, equipment investment is big, the operating maintenance complexity.
Summary of the invention
The purpose of this utility model is improved and is innovated at the defective that exists in the background technology and problem, provides a kind of investment little, the online pressure back purge system of cooler that operating maintenance is simple and economical and practical.
The technical solution of the utility model is a kind of flusher that is arranged on the cooler cooling pipeline of being made up of cooling water inlet pipe road and cooling water outlet pipe road on the cooler that comprises of structure, wherein:
The cooling water inlet pipe road is provided with the rinse water drainage pipeline, and cooling water outlet pipe road and rinse water drainage pipeline composition cooler cleaning pipeline;
All be provided with the control valve of the corresponding pipeline of control on described cooling water inlet pipe road, cooling water outlet pipe road and the rinse water drainage pipeline.
Advantage of the present utility model and beneficial effect:
The utility model equipment investment is little, does not take up an area of; Simple to operate, convenient.The utility model is a drain valve by on cooler circulating water pipeline the rinse water discharge line being set, and by changing the flow direction of cooler recirculated water, cooler is carried out wash cycles, and dirt is outside drain valve is discharged to system in the pipe.Make full use of the circulation hydraulic power, need not to increase power, realized the online pressure recoil of cooler cleaning.
Description of drawings
Fig. 1 is the utility model surface structure schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model comprises that being arranged on the cooler of being made up of cooling water inlet pipe road 3 and cooling water outlet pipe road 2 on the cooler 1 cools off pipeline, wherein:
Cooling water inlet pipe road 3 is provided with rinse water drainage pipeline 4, and cooler cleaning pipeline is formed with rinse water drainage pipeline 4 in cooling water outlet pipe road 2;
All be provided with the control valve 5 of the corresponding pipeline of control on described cooling water inlet pipe road 3, cooling water outlet pipe road 2 and the rinse water drainage pipeline 4.
Cooling water inlet pipe described in the utility model road 3 and 4 alternations of rinse water drainage pipeline, both and cooling water outlet pipe road 2 form the cooling pipeline and clean pipeline.Described cooling water inlet pipe road 3 and rinse water drainage pipeline 4 are connected the bottom of cooler 1.Described cooling water outlet pipe road 2 is connected the top of cooler 1.
Operation principle of the present utility model:
When cooler need clean, close recirculated cooling water inlet channel control valve, open rinse water discharge line control valve, allow the circulating hot water adverse current in the cooling water outlet pipe road enter heat exchanger from top, discharge from the rinse water discharge line again; After cleaning a period of time, open recirculated cooling water inlet channel control valve again, close rinse water discharge line control valve, recover original flow direction.So repeatedly several times, just can reach the purpose of cleaning cooler, and in the process of cleaning, can not stop work fully, realize on-line cleaning, can not produce what influence cooling logistics cooling effect.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
