Abstract
The invention provides a dual-circulation injection reactor. The dual-circulation injection reactor is composed of a primary reaction kettle (4) with an injector, a secondary reaction kettle (3) with an injector, a circulation pump, a connection pipeline, a set of raw material storage tank and a product outlet pipe. The reaction kettle with the injector is structured by installing a jet-type venturi injector on the upper part of the reaction kettle. The injector (1) corresponds to the secondary reaction kettle (3). The injector (2) corresponds to the primary reaction kettle (4). Liquid raw materials enter from the tops of the injectors. Gas raw materials enter from the side surfaces of the injectors. The lower part of the reaction kettle is provided with a product outlet. The product outlet is connected to an inlet pipe of the circulation pump and then connected back to top inlets of the injectors of the reaction kettle. Through a dual-circulation injection type reaction system, gas and liquid react more completely.
Description
Technical field
The present invention relates to a kind of pair of cyclic spray reactor, belong to chemical field, be specifically related to the application that gas, liquid react.
Background technology
Chemical reaction often relates to gas liquid reaction, gas liquid reaction belongs to heterogeneous reaction, and the degree that is absorbed of the speed of reaction and gas depends primarily on the dissolution degree of gas in liquid, and gas solubility in liquid is high, then gas liquid reaction degree is large, reacts more complete.Often run into the course of reaction of gas and the liquid of water-soluble difference, as process the reaction of heavy metal-containing waste water with hydrogen sulfide gas, in the time of 20 ℃, one premium on currency can only dissolve 2.61 liters of hydrogen sulfide gas (temperature is high, and solubility diminishes), because hydrogen sulfide is water-soluble bad, the water-soluble rear sulphion that ionizes out is considerably less, very low with the concentration of heavy metal ion reaction, cause the reaction time long, the heavy metal ion content after the reaction in the waste water is still very high.Present gas-liquid reactor, relatively simple for structure, the gas liquid reaction time is long, and utilization rate of equipment and installations is low, for the smaller situation of gas solubility in liquid, often causes gas liquid reaction incomplete, the shortcomings such as gas liquid reaction time speciality.
Summary of the invention
Slow for existing gas-liquid reactor gas liquid reaction, react the shortcoming such as not thorough, the invention provides a kind of pair of cyclic spray reactor, under high-pressure injection, can greatly increase the solubility of gas in liquid, increase the reaction contact-making surface of gas and liquid, accelerate the gas liquid reaction process, and by two circular response processes, gas liquid reaction is more thorough.The present invention can be widely used in production, sulfurization-precipitation method removing heavy metals, the sulfuration method metallurgy industry of processing, the chemical products of pernicious gas or relate to the chemical process of gas liquid reaction.
Technical scheme of the present invention is as follows:
A kind of pair of cyclic spray formula reactor, it is characterized in that: by two first order reaction stills with injector) and second order reaction still, circulating pump, connecting pipe and a cover raw material storage tank and product outlet formation, described reactor with injector is the venturi-type eductors that a jetting type is installed on the top of reactor, injector 1 corresponding second order reaction still, injector 2 corresponding second order reaction stills, liquid charging stock enters from the injector top, and gas raw material enters from the side of injector; Products export is arranged at the bottom of reactor, is connected to the top entrance that takes back the injector of this reactor behind the inlet tube of circulating pump; The lower end of injector 1 is connected with reactor with a pipeline; The lower end of injector is connected with reactor with a pipeline, the bottom of reactor is communicated with the charging aperture of circulating pump with pipeline, the bottom of reactor is communicated with the charging aperture of circulating pump with pipeline, the discharging opening of circulating pump is connected with the top of injector 1, the discharging opening of circulating pump is connected with the top of injector 2, connect with pipeline between two injectors, also be connected with pipeline between two reactors; Raw material liq storage tank bottom with pipeline and circulating pump, feed end link to each other; The top of gas reservoir with pipeline with injector, be connected.
Above-mentioned two cyclic spray reactors are applied to metallurgy industry, mining industry, electroplating industry, battery processing industry, machining, sulfuric acid industry, the application of the heavy metal-containing waste water removal heavy metal aspect that the chemical industry such as phosphoric acid industry produce or the application of the application of the absorption processing aspect of pernicious gas or mining and metal hydrometallurgy aspect.
The course of work of the present invention: gas raw material enters the side pipeline opening of the injector of second order reaction still by pipeline from gas reservoir, liquid enters injector from the top of injector, gas-liquid reacts, reactant liquor enters the second order reaction still, outlet at bottom pipeline by the second order reaction still enters circulating pump, squeezed into the top of injector by pipeline by circulating pump, circular response drains into the reactant liquor storage tank after a period of time; Residual gas enters the side pipeline opening of the injector of A reactor, raw material liq enters circulating pump from the bottom sides pipeline opening of raw material liq storage tank, the top duct entrance of being squeezed into injector by circulating pump enters injector, react with gas, mixed liquor enters the first order reaction still, enter circulating pump from the outlet conduit of first order reaction still bottom, squeezed into the top of injector by pipeline by circulating pump, circular response is complete to gas consumption, and reacted liquid is as the liquid charging stock of second order reaction still circular response.
Advantage of the present invention is:
1, use the reaction condition of two cyclic spray formulas, liquid material sprays into from the top of injector, produces negative pressure, automatic sucking gas under large pressure, increases the solubility of gas in liquid, liquid material contacts more abundant with gas, accelerated gas-liquid reaction process, and gas liquid reaction is more complete.
2, react under the airtight environment, the gas circulation reaction has reduced the pernicious gas contaminated environment to fully.
3, with the sulfide precipitation agent of hydrogen sulfide gas as heavy metal, use this pair cyclic spray formula reactor, heavy metal removing rate is high, and clearance is greater than 99%.
