Drawings
FIG. 1 is a schematic view of a folded-range non-contact rapid cooling tower.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1, the structure of the non-contact rapid cooling tower with a folding stroke comprises a flue gas inlet 1, a flue gas outlet 2, a cooling water outlet 3, a cooling water array pipe 4, a folding plate 9, a cooling tower shell 5, a cooling water inlet 6, a condensed water emptying valve 7, a vent valve 8 and an access hole 10;
the flue gas inlet is arranged at the top of the cooling tower;
the flue gas outlet and the cooling water outlet are arranged at the upper part of the cooling tower body;
the cooling water tubes 4 are arranged in the cooling tower and comprise a plurality of cooling water tubes, the cooling water tubes are uniformly arranged at intervals, and the folded plates 9 are arranged among the cooling water tubes;
the cooling water inlet 3 and the condensed water emptying valve 7 are arranged on a bottom pattern plate of the shell side of the cooling tower body;
the vent valve 8 is arranged at the upper part of the cooling tower, so that the pressure inside and outside the tower is kept consistent.
The outside of the tube array is filled with cooling water, the cooling water is pressurized and supplied to the bottom of the shell pass through a cooling water pump, and the cooling water exchanges heat with the flue gas in the tube array in a reverse direction from bottom to top and then flows to a cooling water tank through a water outlet at the top.
The flue gas air inlet is established at the top, and through setting up the folded plate in the cooling tower, the flue gas is circuitous turning back under the water conservancy diversion effect of folded plate, through pipe wall contact heat transfer in the tube side to reduce the flue gas temperature rapidly, discharge from the flue gas outlet that sets up at the top at last. And condensing part of water vapor in the flue gas, collecting the condensed water vapor at the bottom of the cooling tower, and emptying the condensed water vapor through an emptying valve.
The cooling tubes are provided with certain pores and are uniformly arranged in the tower, dynamic cooling water is filled outside the tubes, water is supplied from the bottom of the cooling tower by an externally connected cooling water pump, the cooling water circularly overflows in a shell pass, and finally overflows to a cooling water pool from the upper part of the cooling tower through a ventilation valve pipeline. The flue gas is through contacting the cooling shell and tube inner wall to reach the rapid cooling effect, cross the temperature reaction section of dioxin regeneration, the effectual generation that has reduced the dioxin. After meeting the condensation, part of the vapor in the flue gas slides from the wall of the tube array to the bottom of the tower to be collected and is emptied through a bottom emptying valve.
The flue gas with high temperature is rapidly cooled after entering the cooling tower for cooling, the cross section of a chimney flow passage is changed from big to small after the flue gas is baffled by the folded plate 9, and the flow speed of the flue gas is kept consistent before and after the temperature change according to the calculation of the Gao-Lussac law, so that the operation working conditions of the tube array structure tend to be consistent, and the service life of the cooling tower and the stability of the process working conditions are ensured.
