Description
Technical field: the present invention relates to gas discharging technology, the mass-and heat-transfer device that especially a kind of absorption tower and heat exchanger unite two into one and the method for works such as chemical industry, petrochemical industry, environmental protection, medicine.
Background technology: in Chemical Manufacture, a large amount of ammonia cannot recycling completely, causing a large amount of ammonia gas is discharged in air with emptying, ammonia is a kind of toxic gas of colourless irritant foul odour, great pollution is caused to environment, also create a large amount of wastes, economic loss is serious.Due to factors such as design and structures, some tail gas absorbers, do not play the effect of absorption, especially when summer temp is high.Because the ammonia gas in tail gas will be released a large amount of heats when absorbing, and heat cannot be taken away in common absorption tower, makes the constant temperature in absorption tower increase, and reduces when temperature raises solubility, cannot absorb completely at all.
Summary of the invention: the object of this invention is to provide mass-and heat-transfer device and method of work that a kind of absorption tower and heat exchanger unite two into one, which overcome the shortcoming of original technology, the object of the present invention is achieved like this, it is by gas vent, absorbent inlet tube, shower nozzle, sieve plate, cooling water inlet, deflection plate, tube bank, coolant outlet, low head, liquid outlet, gas feed, tube sheet, discharge outlet, heat exchanger tube, upper cover, flange, filler is formed by connecting, on the top of tube bank, upper cover is installed, the front, top of upper cover there is gas vent, an absorbent inlet tube is installed on upper cover top, the side, upper end of tube bank is provided with cooling water inlet, the side, lower end of tube bank is provided with coolant outlet, the lower end opposite side of tube bank is provided with discharge outlet, in the bottom of tube bank 7, low head is installed, the side of low head is provided with gas feed, the bottom of low head is provided with liquid outlet.
In the bottom of absorbent inlet tube, shower nozzle is installed, and on absorbent inlet tube, flange is installed; Shower nozzle is the corrosion resistant plate of arc, and with square arrangement, hole count is multiple.
Shower nozzle be fixed wtih one piece of sieve plate below, tube bank be fixed wtih another block sieve plate below, porose on two pieces of sieve plates, hole is with equilateral triangle arrangement.
Being installed with by two pieces of tube sheets, five pieces of deflection plates in the centre of upper and lower two pieces of sieve plates is 1/4 breach, and between two pieces of tube sheets, be installed with several heat exchanger tube, heat exchanger tube is with equilateral triangle arrangement; The filler of filling Φ 1.5mm-2.0mm in heat exchanger tube.
During work, the present invention takes away heat by increasing heat-exchanging tube bundle, makes shower water can absorb ammonia in tail gas completely.Tail gas walks tube side from lower to upper by gas feed, and shower water also walks tube side from top to down from shower nozzle, after the ammonia in tail gas is absorbed by shower water in tube bank, is discharged and recycles, residual exhaust emptying by bottom; Must take away the heat of generation completely for ensureing to absorb, therefore recirculated water walks shell side, to be intake to coolant outlet water outlet, form circulation by cooling water inlet.
Meaning of the present invention is: the temperature 1, reducing this equipment, achieves the absorption of device to ammonia in tail gas, decreases the waste of ammonia, reduce production cost; 2, achieve the multipurpose on similar absorption tower, multi-state uses.Achieving ammonia in Chemical Manufacture tail gas cannot the present situation of recycling completely; 3, by increasing former tower height degree, tube bank and internals, realize different instructions for uses, can meet Production requirement, atmospheric environment have also been obtained very large improvement; 4, gas plant ammonia can better be solved with the irretrievable problem of exhaust emissions, for gas plant high load capacity long-term operation lays the first stone.
Accompanying drawing illustrates: Fig. 1 is the structural representation of the mass-and heat-transfer device that a kind of absorption tower and heat exchanger unite two into one, in figure 1, gas vent 2, absorbent inlet tube 3, shower nozzle 4, sieve plate 5, cooling water inlet 6, deflection plate 7, tube bank 8, coolant outlet 9, low head 10, liquid outlet 11, gas feed 12, tube sheet 13, discharge outlet 14, heat exchanger tube 15, upper cover 16, flange 17, filler
Detailed description of the invention: embodiment 1, the present invention are formed by connecting by gas vent 1, absorbent inlet tube 2, shower nozzle 3, sieve plate 4, cooling water inlet 5, deflection plate 6, tube bank 7, coolant outlet 8, low head 9, liquid outlet 10, gas feed 11, tube sheet 12, discharge outlet 13, heat exchanger tube 14, upper cover 15, flange 16, filler 17, on the top of tube bank 7, upper cover 15 is installed, the front, top of upper cover 15 there is gas vent 1, on upper cover 15 top, an absorbent inlet tube 2 is installed; The side, upper end of tube bank 7 is provided with cooling water inlet 5, the side, lower end of tube bank 7 is provided with coolant outlet 8, the lower end opposite side of tube bank 7 is provided with discharge outlet 13; In the bottom of tube bank 7, low head 9 is installed, the side of low head 9 is provided with gas feed 11, the bottom of low head 9 is provided with liquid outlet 10.
