Description
Technical field
The utility model is specifically related to the absorption treating device of ammonia in a kind of nitriding furnace waste gas.
Background technology
Ammonia is a kind of toxic gas of colourless irritant stench, and ammonia has corrosion and spread effect to the skin histology of contact.Ammonia has and stimulates and corrosiveness the upper respiratory tract of animal or human's body, and ammonia easily enters blood by alveolar after being inhaled into lung, is combined with hemoglobin, destroys fortune oxygen function.Suck in a short time after a large amount of ammonias can occur shedding tears, pharyngalgia, hoarseness, cough, sputum streaked with blood silk, uncomfortable in chest, expiratory dyspnea, can be with dizzy, headache, feel sick, vomiting, weak etc., can there is pulmonary edema, ARDS in severe patient, respiratory tract symptom may occur simultaneously.If suck ammonia too much, cause ammonia excessive concentration in blood, will by the reflex of trigeminal neuralgia tip cause heart stop fight and breath stopped, threat to life.Long Term Contact ammonia, may there is the symptom such as Skin pigmentation or finger ulcer in groups of people.
So in industrial production, we will reclaim the waste gas of the ammonia producing in industrial production, tail gas, can not make ammonia directly be emitted in the middle of air, cause ammonia poisoning to occur.And the waste gas of ammonia, tail gas recycle normally utilize ammonia physical characteristic soluble in water, ammonia is directly passed into let out in ammonia pond ammonia is dissolved in water, to reach not directly to the in line object of putting of sky.
But when the nitriding furnace nitriding in heat treatment industry, liquefied ammonia is meeting discharging waste gas after pyrolytic, and the main component of waste gas is ammonia, hydrogen and nitrogen.What the sector was not suitable for that preparation can absorb ammonia lets out ammonia pond, because this method can be wasted a large amount of water resources.
Therefore, be badly in need of a kind of device that absorbs ammonia in nitrogenize furnace exhaust that is specifically designed to of design.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of nitriding furnace emission-control equipment, this device can, in absorbing the ammonia of processing in waste gas, reach the object of saving water.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of nitriding furnace emission-control equipment, comprise cylindrical shell, described cylindrical shell is provided with water inlet, delivery port, air inlet and gas outlet, described delivery port is located at the bottom of cylindrical shell, the top of cylindrical shell is located in described water inlet, air inlet and gas outlet, and described air inlet is provided with towards the pipeline in cylindrical shell, and the bottom of described pipeline is near the bottom of cylindrical shell.
Preferably, on described cylindrical shell, be also provided with pH value detector.
Preferably, described water inlet is provided with entering water electromagnetic valve, and described delivery port is provided with out water solenoid valve, described entering water electromagnetic valve with described in go out water solenoid valve and be all connected with described pH value detector signal.
The utility model advantage is compared with prior art:
Simple in structure, easy to use; Can realize the process of automatic control exhaust-gas treatment, practical effect is good; In solving exhaust emission, using water wisely.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment 1.
As shown in Figure 1, a kind of nitriding furnace emission-control equipment, comprise cylindrical shell 1, described cylindrical shell is provided with water inlet 2, delivery port 3, air inlet 4 and gas outlet 5, described delivery port 3 is located at the bottom of cylindrical shell 1, the top of cylindrical shell 1 is located in described water inlet 2, air inlet 4 and gas outlet 5, and described air inlet 4 is provided with towards the pipeline 6 in cylindrical shell 1, and the bottom of described pipeline 6 is near the bottom of cylindrical shell 1.Water inlet and delivery port are equipped with switch.
When work, open the switch of water inlet, running water enters cylindrical shell by water inlet, and the water surface must not have the bottom of piping, and the water yield is that the 1/3-1/2 of cylindrical shell volume is comparatively suitable.Pass into waste gas, waste gas rises from the bottom of pipeline, and in this process, the ammonia in waste gas is dissolved in water, becomes ammonia spirit, is alkalescent, and chemical equation is NH
3+ H
2o=NH
3h
2o.Waste gas (hydrogen and nitrogen) after water absorbs enters atmosphere from gas outlet.With the pH value of PH detection paper ammonia spirit, in the time that pH value reaches 8, can open the switch of delivery port, open the switch of water inlet simultaneously, reduce the pH value in cylindrical shell, to ensure that the ammonia in waste gas can be absorbed by water completely.
Embodiment 2.
As shown in Figure 2, this example is with the difference part of embodiment 1: water inlet 2 is provided with entering water electromagnetic valve 7, delivery port 3 is provided with out water solenoid valve 8, cylindrical shell 1 side is provided with pH value detector 9 away from a side of water inlet, described entering water electromagnetic valve with described in go out water solenoid valve and be all connected with described pH value detector signal.Make it to become a pH value automatic control system.Other arranges all identical.
PH value detector and magnetic valve are all firsthand.PH value automatic control system belongs to prior art, just this system is still belonged to the first time for emission-control equipment of the present utility model, at this, it is not described further.
When work, while setting PH>8, open water inlet and delivery port simultaneously, when PH<7.5, close water inlet and delivery port.
Constantly in water, pass into the waste gas that contains ammonia by pipeline, ammonia forms alkaline ammonia spirit after being absorbed by water, pH value detector can pass to pH value information in real time entering water electromagnetic valve and go out water solenoid valve, in the time of PH>8, pH value detector passes to signal entering water electromagnetic valve and goes out water solenoid valve, and they start working simultaneously, now, waste water is constantly discharged, and new water constantly injects, thus the pH value of continuous dilute aqueous solution.In the time of PH<7.5, pH value detector passes to signal entering water electromagnetic valve and goes out water solenoid valve, and they quit work simultaneously, to reach the object of water saving.
The utility model advantage is compared with prior art: simple in structure, easy to use; Can realize the process of automatic control exhaust-gas treatment, practical effect is good; In solving exhaust emission, using water wisely.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
