Description
technical field:
The utility model and air cooling heat exchanger restrain that to overhaul attemperator winter relevant.
background technology:
When air cooling heat exchanger overhauls in the winter time, after equipment stopping, high-temperature medium no longer passes through air cooler tube bundle and at low ambient temperatures, easily freezes the intrafascicular residual liquid of air cooler inner tube, thus cause breaking of air cooler tube bundle; It is adopt heating calancria that traditional air cooler overhauls insulation winter, its structure increases a heating calancria in the middle of air cooler tube bundle and framework, heating calancria is interior by high temperature fluid or high-temperature steam, thus ensures that the Liquid Residue of top tube bank does not freeze, and avoids breaking of tube bank.
Its shortcoming is as follows:
One, need to manufacture the heating calancria being equal to air cooler tube bundle area;
Two, scene must possess high temperature fluid or high-temperature steam;
The scheme of this kind of insulation can cause the waste with resource of increasing of cost.
utility model content:
The purpose of this utility model is to provide the air cooler heated air circulation device that a kind of structure is simple, with low cost, easy to operate, economize on resources.
Utility model is achieved in that
Framework 2 is cuboid, the epicoele of framework 2 is formed by surrounding column and Plate Welding, the cavity of resorption of framework 2 is formed by connecting with the 1st side shutter 1, the 2nd side shutter 4 respectively by surrounding column, the blower fan 7 of two parallel connections is had in the cavity of resorption of framework 2, the top of framework 2 is connected with tube bank case 3, some heat exchanger tubes arranged side by side are positioned at tube bank case 3, tube bank case 3 communicates with the epicoele of framework 2 below, tube bank case 3 communicates with hot air circulation case 5 above, the surrounding of hot air circulation case 5 is the steel plate of welding, being connected with top shutter 6 above of hot air circulation case 5.
The utility model, when air cooler normally runs, opens all shutters, and air natural circulates, and air cooler works normally; At air cooler maintenance down for the previous period, closeall shutter, allows air cooler form the airtight device in an inside, inner formation hot air circulation, thus reaches the effect of insulation; Overhaul complete after, then open all shutters, air cooler normally runs.Structure is simple, with low cost, easy to operate, economize on resources.
accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
detailed description of the invention:
Framework 2 is cuboid, the epicoele of framework 2 is formed by surrounding column and Plate Welding, the cavity of resorption of framework 2 is formed by connecting with the 1st side shutter 1, the 2nd side shutter 4 respectively by surrounding column, the blower fan 7 of two parallel connections is had in the cavity of resorption of framework 2, the top of framework 2 is connected with tube bank case 3, some heat exchanger tubes arranged side by side are positioned at tube bank case 3, tube bank case 3 communicates with the epicoele of framework 2 below, tube bank case 3 communicates with hot air circulation case 5 above, the surrounding of hot air circulation case 5 is the steel plate of welding, being connected with top shutter 6 above of hot air circulation case 5.
Air cooler framework 2, air cooler tube bundle case 3 are installed on ground after assembling; Air cooler tube bundle 3 installs hot air circulation case 5, then top shutter 6 is installed; Finally between the column of air cooler framework 2, install side shutter 1,4;
When air cooler normally runs, open all shutters, air natural circulates, and air cooler works normally; At air cooler maintenance down for the previous period, closeall shutter, allows air cooler form the airtight device in an inside, inner formation hot air circulation, thus reaches the effect of insulation; Overhaul complete after, then open all shutters, air cooler normally runs.
Side shutter 1: by Steel Structure and aluminium alloy vane, can be 0-90 ° and can realize open and-shut mode by switch over travel;
Tube bank case 3: by the pressure vessel of high-temperature medium; Formed by steel pipe and Plate Welding; Steel pipe has medium gateway.
Side shutter 4(is with access door): by Steel Structure and aluminium alloy vane, can be 0-90 ° and can open and-shut mode be realized by switch over travel;
Hot air circulation case 5: increase tube bank superjacent air space, increase the circulation area of hot air circulation;
Top shutter 6: by Steel Structure and aluminium alloy vane, can be 0-90 ° and can realize open and-shut mode by switch over travel;
Blower fan 7: outsourcing piece, causes air circulation.
Shown in Fig. 1, cold air enters air cooler from surrounding after being driven by blower fan 7, can see according to the direction of arrow, cold air enters backward upper flowing from air cooler side, there is the fluid of high temperature tube bank case 3 inside, cold air is by below, and being upward through part is after air cooler tube bundle case 3, and cold air has become the air of high temperature; As shown in Figure 2, an air cooler is generally be made up of two Fans 7, after all shutters are closed, close a Fans again, then can see, after hot-air arrives air cooler top, not have in harness blower fan from the right according to the direction of arrow, baffling makes the return trip empty bottom cooler again, thus forms a circulation.
