Description
Technical field: the present invention relates to gas draining technologies such as chemical industry, petrochemical industry, environmental protection, medicine, mass-and heat-transfer device and method of work that especially a kind of absorption tower and heat exchanger unite two into one.
Background technology: in Chemical Manufacture, the recycling fully of a large amount of ammonia, caused a large amount of ammonia gas to be discharged in the atmosphere with emptying, ammonia is a kind of colourless toxic gas that the excitant foul odour is arranged, environment has been caused great pollution, also caused a large amount of wastes, economic loss is serious.Because 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 the tail gas will be emitted a large amount of heats when being absorbed, and heat can't be taken away in common absorption tower, make the temperature in the absorption tower continue to rise, when temperature rising solubility reduces, can't absorb fully at all.
Summary of the invention: the purpose 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, it has overcome the shortcoming of original technology, the object of the present invention is achieved like this, it is by gas vent, the 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, top in tube bank is installed with upper cover, there is gas vent in front, top at upper cover, and an absorbent inlet tube is installed on the upper cover top; Upper end one side in tube bank is provided with cooling water inlet, is provided with coolant outlet in lower end one side of restraining, and is provided with discharge outlet at the lower end opposite side of restraining; Bottom in tube bank 7 is installed with low head, and the side of low head is provided with gas feed, is provided with liquid outlet in the bottom of low head.
Bottom at the absorbent inlet tube is installed with shower nozzle, and at the absorbent inlet tube flange is installed; Shower nozzle is the corrosion resistant plate of arc, and with square arrangement, hole count is a plurality of.
A sieve plate is being fixed by the bottom of shower nozzle, and another piece sieve plate is being fixed by bottom in tube bank, and porose on two sieve plates, arrange with equilateral triangle in the hole.
Be installed with by two tube sheets, five deflection plates to be 1/4 breach, several heat exchanger tubes are installed that heat exchanger tube is arranged with equilateral triangle between two tube sheets in the centre of two sieve plates up and down; The filler of filling Φ 1.5mm-2.0mm in the heat exchanger tube.
During work, the present invention takes away heat by increasing heat-exchanging tube bundle, makes shower water can absorb ammonia in the tail gas fully.Tail gas is walked tube side from lower to upper by gas feed, and shower water is also walked tube side from top to down from shower nozzle, after the ammonia in the tail gas is absorbed by shower water in tube bank, is discharged by the bottom and to recycle residual exhaust emptying; For guarantee absorbing the heat that must take away generation fully, so recirculated water walks shell side, by the cooling water inlet coolant outlet water outlet of intaking, forms circulation.
Meaning of the present invention is: 1, reduced the temperature of this equipment, realized the absorption of device to ammonia in the tail gas, reduced the waste of ammonia, reduced production cost; 2, realized the multipurpose on similar absorption tower, multi-state uses.Realized the ammonia present situation of recycling fully in the Chemical Manufacture tail gas; 3, by increasing former tower height degree, tube bank and internals, realize different instructions for uses, can satisfy the production demand, atmospheric environment has also obtained very big improvement; 4, can better solve the gas plant ammonia with the irretrievable problem of exhaust emissions, for gas plant high load capacity long-term operation lays the first stone.
The structural representation of the mass-and heat-transfer device that description of drawings: Fig. 1 unites two into one for a kind of absorption tower and heat exchanger is among the 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
