Hidden danger.2nd, reactor is after using a period of time, meeting fouling, makes heat exchange property reduce, and increases the reaction time, and aggravation reactor sets
Standby corrosion, so to be carried out to reactor.The conventional cleaning method of reactor has chemical cleaning method and mechanical cleaning process.
Chemical cleaning corrodes kettle, mechanical cleaning then cleaning frequency length, time-consuming.3rd, in the waste gas that the industries such as petrochemical industry are discharged
Hydrocarbon, alcohol, aldehyde, ketone, ether, ester, amine carboxylic acid, aromatic hydrocarbon, the various organic compound from waste gas such as phenols, harmful, organic waste
Gas can also cause photochemical fog, causes secondary pollution, and the purifying treatment method of current organic exhaust gas mainly has absorption method, utilizes
The surface force of adsorbent organic exhaust gas adsorption at adsorbent surface, purifying the waste gas discharged in production process, but typically
Petrochemical enterprise is complicated due to its exhaust gas constituents, is difficult to be fully cleaned up by a kind of method, causes in the tail gas of discharge also
Containing gas harmful in a large number, have a strong impact on the healthy of nearby residents.
Content of the invention
Present invention seek to address that in prior art that the gas got rid of in reactor is detrimental to health, pollutes environment etc. and ask
Topic, provides the convenient chemical industry environmental protection reactor cleaning, this reactor by arranging detector and fire-suppressant gas air inlet pipe,
In real time reactor can be lowered the temperature while each gas concentration and composition when temperature of reaction kettle is too high by detection reactor, keep away
Exempt from the potential safety hazards such as blast on fire, and be connected with gas fractionation unit on gas escape pipe, will discharge after gas purification, simultaneously
Change the structure of agitating device so that agitating device can stir and can automatically clean reactor, simple in construction.
For solving above-mentioned technical problem, the present invention is achieved through the following technical solutions:
The convenient chemical industry environmental protection reactor cleaning, including kettle, is provided with agitating device in described kettle, described kettle upper
Portion's sidewall is provided with gas escape pipe, charging aperture and fire-suppressant gas air inlet pipe, and described agitating device includes shaft, described stirring
Being provided with the paddle of curve shape on axle, described shaft is to offer spray-hole on hollow shaft and its sidewall, described
The top of shaft and be positioned in the part outside kettle and be connected with cleaning fluid feed tube, described cleaning fluid feed tube is connected with and adds
Press pump, described force (forcing) pump is connected with cleaning fluid storage tank, described gas escape pipe is connected with detector and separates dress with gas
Putting, described detector being connected with alarm, described kettle is arranged on kettle support.
Further, described shaft is for being connected in sequence by some sections of shaft unit, described shaft unit it
Between be flexibly connected.
Described gas fractionation unit includes box gas-gas heat exchanger and the combustion chamber being sequentially connected with, described box gas-gas heat exchange
Device is connected on gas escape pipe.
Further, described paddle is " S " type paddle.
Further, one end of described shaft unit is provided with groove, and the other end is provided with projection.
Further, the sidewall in described projection and groove is provided with the screw thread cooperating.
Beneficial effects of the present invention is as follows：
The present invention is by being hollow-core construction at the Agitation speed of existing agitating device and offering injection on the sidewall of shaft
Hole, so, when needs clean reactor, only need to open agitating device and the cleaning fluid feed tube being connected with shaft,
Cleaning fluid is stirred under the effect of device being carried out reactor, it is not necessary to manual cleaning, cleans quick, simply, it is to avoid use
Chemical cleaning solution cleans the problem of corrosion reacting kettle, and cleaning fluid is pressurizeed by the force (forcing) pump of the present invention, thus effective to reactor
It is carried out.The present invention by reactor connect detector, thus in examinations reactor gas composition and
Gas concentration, thus the separator of gas and the selection of method for later stage discharge provides foundation, connects on detector simultaneously
There is alarm, report to the police when detecting to trigger when toxic gas or fuel gas exceed finite concentration, in order to operating personnel take
Control measure, this reactor is by arranging detector and fire-suppressant gas air inlet pipe, and in detection reactor, each gas is dense in real time
When temperature of reaction kettle is too high, reactor can be lowered the temperature while degree and composition, it is to avoid the potential safety hazards such as blast on fire, this
Invention is connected with gas fractionation unit on gas escape pipe, is purified after gas efficiently separates recovery, free from environmental pollution.
The shaft of the present invention forms for being flexibly connected successively by some sections of shaft unit, so facilitate by shaft from
Reactor takes out cleaning, maintenance etc..
