Description
[technical field]
The utility model relates to energy saving standard field, particularly a kind of synthetic energy-saving discharge-reducing device utilizing stack gas waste heat to recycle ammonia-containing water.
[background technology]
Take coal as the fertilizer plant of raw material production bicarbonate of ammonia and be raw materials for ethylene production with coal, the coal chemical industry enterprises of ethanol all produces a large amount of ammonia-containing waters in their gas washing or carbonization washing process, gas furnace and gasification burner also can produce the stack gas spending even higher temperature 200 DEG C more in gas maked coal process.Due to gas maked coal or carbonization washing water containing ammonia density higher and complicated component, therefore the treatment and discharge of washing water becomes a great problem of these enterprises; And containing, for example corrosive gasess such as sulfurous gas, sulphur trioxide, hydrogen sulfide in high-temperature flue gas, when UTILIZATION OF VESIDUAL HEAT IN is carried out to it, when effluent gas temperature is down to the acid dew point of sulphur trioxide, the sulfuric acid that condensation is got off can produce dew point corrosion to the flue gas cools pipe of carbon steel material or water cooler, therefore, high-temperature flue gas in gas maked coal process is difficult to be applied fully, such high-temperature flue gas both can produce Greenhouse effect after entering air, can acid rain be formed again, thus dual harm is caused to environment.For above-mentioned reasons, the recycling of ammoniacal liquor and the waste heat efficiency utilization of high-temperature flue gas are not yet accomplished to ammonia-containing water by current domestic many gas maked coal enterprises, which results in useful ammonia resource and the waste of heat energy.Therefore, employ new technology, the ammonia-containing water of novel method to gas maked coal enterprise recycle, and carry out to high-temperature flue gas the important topic that efficiency utilization has become energy-saving and emission-reduction.
[utility model content]
(goal of the invention) the purpose of this utility model not yet obtains efficient recovery process and high-temperature flue gas for the strong ammonia wastewater existed in current gas maked coal and coal chemical industry enterprises not yet to obtain the present situation that efficient waste heat utilizes, develop a kind of simplicity of design, rational in infrastructure, easy to use, a kind of Integral energy-saving emission reduction device that ammonia in wastewater can be made to obtain high efficiente callback and stack gas waste heat be utilized effectively.
(technical scheme) for achieving the above object, the technical solution adopted in the utility model is: provide a kind of stack gas waste heat that utilizes to carry out the energy-saving and emission-reduction integration unit of Ammonia recovery process to ammonia-containing water, this device comprises ammonia-containing water evaporating pot, ammonia absorption tank, stack gas bundle pipes, water-sealed tank, ammonia circulation pump and liquidometer.
Described stack gas bundle pipes is placed in waste water evaporating pot, and the high-temperature flue gas in bundle pipes carries out heating evaporation to the ammonia-containing water in waste water evaporating pot; Further, described stack gas bundle pipes and waste water evaporating pot junction are provided with high temperature resistant, corrosion resistant sealing member.
Described ammonia absorption tank top arranges shower nozzle or shower, carries out spray-absorption to the ammonia from waste water evaporating pot, discharges when the ammoniacal liquor in tourie reaches available ammonia circulation pump after certain setting concentration; Further, the water inlet pipe on described ammonia absorption tank top is by valve opening and the concentration closing ammoniacal liquor bottom adjustable tourie, and the water added, according to purposes or user's needs, can be deionized water, tap water or process water.
Described water-sealed tank is an opened type container, and the acid tap water of about three volumes of four parts or acid process water are housed in container, is mainly used to dissolve from the gaseous ammonia of tourie top effusion, effectively may to prevent gaseous ammonia from entering air and work the mischief; Described ammonia circulation pump is placed in ground, its effect be by tourie bottom weak ammonia beat to top, absorbing more ammonia by spray mode becomes strong aqua;
Described withstand voltage gage glass is arranged at the correct position of waste water evaporating pot and ammonia absorption tank, and its effect is the altitudes of liquid in each tank body of grasp and processes pot liquid in good time.(beneficial effect) the utility model integration unit novel structure, simple to operate, corrosion protection of equipment and resistance to elevated temperatures good, long service life, the operation of complete assembly can carry out high efficiente callback to the strong ammonia wastewater of gas maked coal and coal chemical industry enterprises, turns waste into wealth; Can carry out effective UTILIZATION OF VESIDUAL HEAT IN to high-temperature flue gas, effect is good, and energy-saving effect is remarkable.
Fig. 1 is the device schematic diagram of the utility model embodiment.
Accompanying drawing illustrates:
1, waste water vaporizer; 2, ammonia absorption tank; 3, water-sealed tank; 4, wastewater inlet pipe; 5, stack gas bundle pipes; 6, raffinate treatment zone pipeline is removed; 7, water cycle spray absorption pipeline; 8, ammoniacal liquor goes to utilize district's pipeline; 9, filling pipe; 10, ammonia circulation pump; 11, gage glass.Specific implementation method
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, enter waste water evaporating pot 1 containing ammoniacal liquor by wastewater inlet pipe 4, by the high-temperature gas in stack gas bundle pipes 5, ammonia-containing water is heated; After waste water ebuillition of heated, ammonia wherein and part water vapour enter in ammonia absorption tank 2 from the top of evaporating pot 1 by vapor delivery line in a gaseous form, become weak ammonia with being adsorbed in water after the water coke slurry heat under tourie 2 top spray, weak ammonia continues spray-absorption ammonia with ammonia circulation pump 10 dozens to tourie 2 top again, circulate and so forth, ammonia concn bottom tourie 2 progressively raises, when ammonia concn reaches the concentration of a certain setting, squeezed into ammonia circulation pump 10 and utilized district; When saturation concentration under ammonia concn continues to be increased to certain temperature, open the filling pipe 9 at tourie 2 top, with deionized water or process water, strong aqua diluted, the part ammonia of overflowing in supersaturation strong aqua in water-sealed tank 3 by sour water in and, absorb.When the gage glass 11 on ammonia absorption tank 2 shows that in tank, ammoniacal liquor liquid level is higher, by ammonia circulation pump 10 ammoniacal liquor pumped into and utilize district to reduce ammoniacal liquor liquid level; When the gage glass 11 on waste water vaporizer 1 show raffinate liquid level higher time, by removing raffinate treatment zone pipeline 6, raffinate is sent to waste water processing station and carries out degree of depth wastewater treatment.
