Abstract
The utility model discloses a polycarboxylic water reducing agent waste gas treatment device. In the production process of an existing polycarboxylic water reducing agent, most of enterprises do not adopt the waste gas treatment and the treatment effect obtained by a simple method adopted by individual enterprises is poor. The polycarboxylic water reducing agent waste gas treatment device comprises an alkaline washing tower and is characterized by also comprising an induced draft fan, a circulating pump for ensuring alkali liquor in the alkaline washing tower to flow and a pH tester for detecting the pH value of liquid at the bottom of the alkaline washing tower, wherein an inlet of the induced draft fan is connected with an outlet at the top of the alkaline washing tower by a pipeline; and the circulating pump and the pH tester are respectively connected with the alkaline washing tower by pipelines. According to the utility model, by effectively adsorbing waste gas generated in the production process, the damage to a human body and the environment is avoided.
Description
Technical field
The utility model relates to waste gas treatment equipment, is used to handle the device of waste gas in specifically a kind of polycarboxylate water-reducer production process.
Background technology
Polycarboxylate water-reducer is a kind of environment-friendly type concrete additive, has become the main product of additive.But because its chemical raw material smell that adds in process of production is very big, like acrylic acid, methacrylic acid, TGA etc.Feed intake with course of reaction in, acrylic acid, raw material highly volatiles such as TGA; Human body and environment are worked the mischief, and most enterprises all do not carry out exhaust-gas treatment at present, and the volatilization that condenser suppresses raw material is also just installed additional in indivedual enterprises on polymerization reaction kettle; Or directly waste gas is fed in the water with pipeline; The treatment effect that these methods obtain is not good, and pungent at workshop and peripheral region smell, air pollution is serious.
The utility model content
The purpose of the utility model provides a kind of polycarboxylate water-reducer emission-control equipment, and it is used for effectively absorbing the waste gas that the polycarboxylate water-reducer production process produces, and makes human body and environment avoid harm and pollution.
For this reason; The utility model adopts following technical scheme: the polycarboxylate water-reducer emission-control equipment; Comprise caustic wash tower; It is characterized in that: it also comprises air-introduced machine, make circulating pump that the alkali lye in the caustic wash tower flows and the pH analyzer that is used to detect caustic wash tower bottom liquid pH value, and the inlet of said air-introduced machine passes through pipeline and is connected with the top exit of caustic wash tower, and circulating pump is connected with caustic wash tower through pipeline respectively with the pH analyzer.The waste gas that feeds intake and produce when reacting mouthful is transported in the caustic wash tower by air-introduced machine through production equipment row, and circulating pump circulates alkali lye in caustic wash tower, can be discharged into sewage-treatment plant automatically when reacted solution is up to standard after the pH analyzer detects.
As preferably, the outlet of said air-introduced machine connects an air draft tube, and the tail gas that air-introduced machine produces is discharged into the top, workshop through the air draft tube.
As preferably, ceramic cascade ring filler is housed in the described caustic wash tower, increased the gas-liquid contact area.
As preferably, three grades of spray absorption systems are housed in the described caustic wash tower, waste gas and alkali lye are fully reacted, remove harmful sour gas.
As preferably, described caustic wash tower is connected with the exhaust outlet of equipment through pipeline, and valve is housed on the pipeline, is used to control the flow of waste gas.
As preferably, described pipeline adopts the PPR pipe, and the PPR pipe is alkaline-resisting, long service life.
The utlity model has following beneficial effect:
1. the waste gas through producing in effective absorption production process has been avoided the harm that human body and environment are caused.
2. reasonable in design has increased the contact area of gas-liquid two-phase, reacts more abundant, and exhaust-gas treatment is more thorough.
3. the utility model has pH value automatic measuring equipment, and back discharge water up to standard can be transported to sewage-treatment plant, need not Artificial Control.
Below in conjunction with the Figure of description and the specific embodiment the utility model is done further explain.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The polycarboxylate water-reducer emission-control equipment by caustic wash tower 1, air-introduced machine 2, the pH analyzer 4 that makes the circulating pump 3 that the alkali lye in the caustic wash tower flows and be used to detect caustic wash tower bottom liquid pH value forms; The inlet of said air-introduced machine is connected with the top exit of caustic wash tower through pipeline; The outlet of air-introduced machine connects air draft tube 5, and circulating pump is connected with caustic wash tower through pipeline respectively with the pH analyzer.Ceramic cascade ring filler and three grades of spray absorption systems are housed in the caustic wash tower.Described caustic wash tower is connected with the exhaust outlet of equipment through pipeline, and valve is housed on the pipeline, and described pipeline adopts the PPR pipe.1.4 meters of caustic wash tower diameters, high 4.5 meters, handle air quantity 5000M
3/H, equipment resistance 510Pa, importing and exporting pipe diameter is 0.45 meter.Air-introduced machine air quantity 5480 M
3/H, total head 1813Pa, rotating speed 2900r/m, power of motor 5.5KW.Caustic wash tower internal circulation pump flow 10 M
3/H, lift 20m, rotating speed 2900r/m, power of motor 2.2KW.
Processing method like the utility model is following: at first alkali lye is injected into the caustic wash tower bottom, and valve-off.Start circulating pump, alkali lye is flowed in tower, open the valve of production equipment and emission-control equipment interface, and open air-introduced machine, waste gas is entered in the caustic wash tower.Acid waste gas fully contacts at ceramic cascade ring filling surface with alkali lye, carries out the acid-base neutralization reaction, and three grades of spray modes of alkali lye employing, and reaction can be more thorough.Reacted liquid can flow to caustic wash tower bottom, joins (three grades of sprays) the caustic wash tower by circulating pump from three positions of tower, continues and the acid waste gas reaction.PH pH-value determination pH appearance can automatically detect the pH value of bottom liquid, will be discharged into sewage-treatment plant automatically after up to standard, if liquid pH value is on the low side, will report to the police automatically, and the injection of fresh alkali lye is carried out in manual work.
