Abstract
The utility model relates to a novel efficient low-resistance mine return air heat exchanger, belongs to the technical field of energy, and solves the problems of lowering of heat exchange efficiency, incapability of meeting the requirement of mine ventilation amount testing and the like due to high resistance generated in the free falling process of circulating water after heat exchange as well as non-uniform air amount distribution on an air outlet section. The novel efficient low-resistance mine return air heat exchanger comprises a mine return air dispersing tower, a drain pipe with a nozzle, a water baffle, a water baffle water collecting groove, a draining pipeline, a water supply pipeline and a flow guide arc, and is structurally characterized in that the water baffle is arranged at a position not less than 1,200 millimeters away from the upper part of the drain pipe with the nozzle, and inclines towards the water collecting groove; the lower part of the water collecting groove is connected with the draining pipeline; water in the draining pipeline is drained into a collecting basin. By adopting the structure, mine return air can be uniformly distributed on the upper part of the dispersing tower, the efficiency of the heat exchanger is increased, and the air current resistance of the heat exchanger is reduced.
Description
Affiliated technical field
The utility model relates to the heat exchanger of the heat exchanger of energy technology field, particularly mine return air and recirculated water.
Background technology
The mine return air heat exchanger of prior art, exists the resistance producing in recirculated water freely falling body process after heat exchange large, and on air outlet section, air quantity skewness causes heat exchange efficiency to decline, and cannot meet mine ventilation and measure the problem such as demand of examination.
Summary of the invention
The shortcoming existing for prior art, the technical problem of the required solution of the utility model is to propose a kind of efficient low-resistance mine return air heat exchanger.It can fully realize the heat exchange of mine return air and the direct efficient low-resistance of recirculated water according to the feature of mine return air retention tower.The utility model solves the technical scheme that its technical problem adopts: a kind of high-efficient low-resistance power mine return air heat exchanger, it is by mine return air retention tower, band nozzle comb, watertight shutter, watertight shutter catch basin, drainage pipe, water supply line, the compositions such as water conservancy diversion arc.Its design feature is, watertight shutter is installed on band nozzle comb top and is not less than 1200mm place, and watertight shutter has the gradient of slope aspect catch basin, and catch basin bottom is connected with drainage pipe, and the water of drainage pipe enters catch basin.Mine return air enters mine return air retention tower by ventilation fan horizontal direction, becomes motion vertically upward after water conservancy diversion arc.
According to such scheme, described watertight shutter air outlet is vertical with blower fan center line wind direction, the distance that watertight shutter is suitable for reading and retention tower is suitable for reading is not less than 500mm, watertight shutter is spacing on whole air outlet section, back draught machine air-out direction increase gradually (for example spacing can be by 22mm gradually to 25mm again to 28mm) be spacing from narrow to wide.With the nozzle number of nozzle comb unit area on whole air outlet section, back draught machine air-out direction reduce gradually (for example unit area nozzle number can by 24 gradually to 20 again to 16) be spray nozzle density apart from by close to thin.Watertight shutter is established the gradient of the one-sided or both sides of slope aspect retention tower, establishes watertight shutter catch basin in one-sided or both sides.
According to technique scheme, watertight shutter material is other metal material such as flame retardant type ABS, PVC, glass steel or stainless steel.Catch basin is V-type or U-shaped.Band nozzle comb is made up of single or two rows, and nozzle water spraying direction is upwards spray all, along uprush direction.
The utility model, owing to having adopted said structure, can make mine return air be uniformly distributed on retention tower top, improves the whole efficiency of heat exchanger, and catch basin adopts V-type or U-shaped design, the resistance being produced to reduce distinguished and admirable shock catch basin.Simultaneously, because the heat exchange recirculated water after being stopped by watertight shutter enters gutter by gutter after entering catch basin, reach and reduced the water yield of recirculated water freely falling body after heat exchange, thereby greatly reduce the gas-flow resistance that heat exchange recirculated water produces in freely falling body process.Because nozzle is all along airflow direction water spray, reduce the water seedling resistance having produced while water spray on the other hand.
Compared with the existing technology, the utility model heat exchange efficiency is high, and the little energy utilization rate of flowing resistance is high.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, from the air-out of Mine Ventilator 7, enter mine return air retention tower 1, under the effect of retention tower water conservancy diversion arc 8, become air-flow vertically upward by horizontal gas flow, uprush by water conservancy diversion arc 8 to air quantity in the direction of ventilation fan 7 from large to small, vertical air quantity is in the process rising, run into band nozzle comb 2, watertight shutter 3, on the one hand with nozzle comb 2 by water conservancy diversion arc 8 in the direction of ventilation fan 7 from dense to sparse, can make the part that air quantity is larger obtain more heat exchange recirculated water, on the other hand because watertight shutter 3 is being broadened by narrow to the direction of ventilation fan 7 by water conservancy diversion arc 8, can make vertical be distinguished and admirablely again uniformly distributed.In addition,, by watertight shutter 3, the heat exchange recirculated water of interception to watertight shutter catch basin 4, then passes through drainage pipe 5 along the slope current of watertight shutter, enters gutter 6, has reduced the quantity of freely falling body recirculated water, further reduces flowing resistance.Vertical air quantity is further being uniformly distributed by watertight shutter 3 is rear, then through being no less than the long straight section of 500mm, is the Mine Ventilator air-quantity measuring condition of providing convenience.The utility model does not change in the situation of retention tower basic structure, makes the position that air quantity is large obtain sufficient heat exchange recirculated water, and further uniform distribution air quantity, has improved greatly heat exchange efficiency and has reduced system wind flowing resistance.
