Abstract
The utility model relates to a series connection device of multiple stages of acrylamide reaction kettles, which is characterized by comprising at least four reaction kettles connected in series with each other, wherein the discharge hole of each stage of reaction kettle is connected with the feeing hole of the next stage of reaction kettle through a pipeline; a filter, a working pump and an ultrafiltration membrane are arranged on the connecting pipeline; a branch pipeline is arranged between the filter and the working pump, and connected to a slag tank; a feed supplement pipeline is arranged at the inlet end of each stage of reaction kettle; and a control valve is mounted on the pipeline. The series connection device has the advantages that the common one-step inter batch reaction kettle is changed into the series connection device of multiple stages of reaction kettles, so that continuous production of the hydration process of producing acrylamide by the microorganism method is realized; and as a result, the quality of the product is more stable and the labor intensity of the worker is greatly reduced.
Description
Technical field
The utility model relates to a kind of acrylamide multi-stage reacting kettle tandem arrangement.
Background technology
The propionyl acid amides is a kind of chemical substance of white crystal, and production method commonly used has chemical method and microbial method.The water of Production of Acrylamide by Microbial Method and workshop section often adopt single still batch production.Single still batch production simple to operately is easy to control, but exists the production cycle long, and labor strength is large, and the shortcoming such as unstable product quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of serialization to produce the multi-stage reacting kettle tandem arrangement of acrylamide.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of acrylamide multi-stage reacting kettle tandem arrangement, it is characterized in that: 4 of reactors that comprise at least mutual series connection, the discharge port of described reactors at different levels is connected by pipeline with next stage reactor opening for feed, described connecting pipeline is provided with strainer, working barrel and ultra-filtration membrane, there is a bypass line to be connected the waste residue groove between described strainer and the working barrel pipeline, described reactor entrance end at different levels is equipped with the feed supplement pipeline, and by-pass valve control is housed on the pipeline.
Preferably, the governor control rotating speed of agitator is housed on the reactors at different levels, is provided with spiral coil cooling tube in the reactor.
Advantage of the present utility model: changing a step batch reactor commonly used is the multi-stage reacting kettle tandem arrangement, realizes the serialization production of Production of Acrylamide by Microbial Method hydrating process, thereby make quality product more stable that labor strength significantly reduces.
Description of drawings
Fig. 1 is acrylamide multi-stage reacting kettle tandem arrangement structural representation in the utility model.
Embodiment
As shown in Figure 1, a kind of acrylamide multi-stage reacting kettle tandem arrangement comprises storage bacterium groove 1, reactor 2, vinyl cyanide storage tank 3, strainer 4, working barrel 5, ultra-filtration membrane 6 and waste residue groove 7.
Described multi-stage reacting kettle comprises 4 of the reactors of mutual series connection at least, the governor control rotating speed of agitator is housed on the reactors at different levels, be provided with spiral coil cooling tube 8 in the reactor, the discharge port of described reactors at different levels is connected by pipeline with next stage reactor opening for feed, described connecting pipeline is provided with strainer 4, working barrel 5 and ultra-filtration membrane 6 in the described reactor, there is a bypass line to be connected waste residue groove 7 between described strainer 4 and the working barrel 5 pipeline pipelines, described reactor entrance end at different levels is equipped with the feed supplement pipeline, and by-pass valve control is housed on the pipeline.
During multistage continuous series connection hydration reaction, thalline in the storage bacterium groove 1, vinyl cyanide and water in the vinyl cyanide storage tank 3 are sent in the reactor 2 through the feed supplement pipeline, open whipping appts, regulate the control temperature of reaction through the spiral coil cooling tube of reactor 2, carry out first order reaction, material after the first order reaction is discharged through the discharge port 9 of reactor 2, after strainer 4 filters, filtrate is sent into ultra-filtration membrane through working barrel 5 and is carried out separating of thalline and material, material is sent into the second order reaction still, thalline is got back to again the utilization of first order reaction still internal recycle, the reaction of sustainable participation catalytic hydration; In the second order reaction still, add raw material mycelium, vinyl cyanide, water by the feed supplement pipeline, carry out hydration reaction, repeat above-mentioned sepn process and enter the third order reaction still, carry out by that analogy multistage still series connection hydration reaction, and by collecting product liquid behind the last step ultrafiltration membrance filter, product concentration is shaved by a certain percentage all and is increased between every first order reaction of while, realized the serialization production of acrylamide, improved plant factor and stablized quality product.
