Abstract
The utility model discloses a catalyst reduction device which is characterized in that an inlet silencer (4), a Roots blower (2), an outlet silencer (3), a vaporizer (5), a reactor (6), a separator (7), a heat exchanger (8) and a cooler (9) are sequentially connected in series through a pipeline from a buffer tank (1). The buffer tank (1) is further connected with a hydrogen pipe (11) and a nitrogen pipe (10). The catalyst reduction device provided by the utility model has the beneficial effects that the cost is lowered, and the strength, service life and conversion ratio of the catalyst are improved.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, particularly a kind of catalyst reduction device.
Background technology
In the methylphenylamine production technology generally all be the mixture of the first alcohol and water that adopts under certain pressure and temperature, carry out reaction decomposes and become hydrogen and carbon monoxide to reduce because the methanol feedstock price is expensive, cost is higher; And owing to contain water in the raw material, all influential to the intensity of catalyst and life-span, conversion ratio.
Therefore need to improve the catalyst reduction device.
Summary of the invention
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of low hydrogen restoring system, utilize the rational proportion of hydrogen and nitrogen that catalyst reactor is reduced.
The technical solution adopted in the utility model is such:
A kind of catalyst reduction device is played to be in series with import muffler, Lodz blower fan, exit silencer, vaporizer, reactor, separator, heat exchanger, cooler successively by pipeline by surge tank, surge tank also is connected to hydrogen pipe and nitrogen tube.
Further, for the gas of discharging in the cooler is realized recycling, described cooler takes back surge tank again, and whole pipeline forms a closed loop.Hydrogen and nitrogen enter in the jar according to certain proportioning, enter the Lodz blower fan through behind the muffler then, come out gas through muffler, pass through flowmeter (the into gas flow of reactor is regulated in bypass) then, gas enters the reactor reduction after heating through vaporizer, come out gas through behind the reacting replacing heat device, go in the jar through subcooler is laggard again.
Further, for course of reaction is followed the tracks of, understand reactiveness, so that timely Adjustment System, sampling control valve in parallel between the outlet of exit silencer and cooler.Analyze by sample valve and relatively to import and export hydrogen content, control and whether need add hydrogen.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, reduces cost, improved intensity, life-span and the conversion ratio of catalyst.
Description of drawings
Fig. 1 is the utility model catalyst reduction structure drawing of device.
Mark among the figure: 1 is surge tank, and 2 is the Lodz blower fan, and 3 is exit silencer, and 4 are the import muffler, and 5 is vaporizer, and 6 is reactor, and 7 is separator, and 8 is heat exchanger, and 9 is cooler, and 10 is nitrogen tube, and 11 is the hydrogen pipe, 12 sampling control valves.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Embodiment 1:
As shown in Figure 1, a kind of catalyst reduction device, be in series with import muffler 4, Lodz blower fan 2, exit silencer 3, vaporizer 5, reactor 6, separator 7, heat exchanger 8, cooler 9 successively by 1 of surge tank, surge tank 1 also is connected to hydrogen pipe 11 and nitrogen tube 10.
Hydrogen and nitrogen enter in the surge tank 1 according to certain proportioning, then through entering Lodz blower fan 2 behind the import muffler 4, come out gas through exit silencer 3, pass through flowmeter (the into gas flow of reactor is regulated in bypass) then, enter after gas heats through vaporizer 5 and carry out reduction reaction in the reactor 6, come out to be cooled off by cooler 9 again behind gas process separator 7 and the heat exchanger 8.
The beneficial effect of present embodiment is: reduced cost, improved intensity, life-span and the conversion ratio of catalyst.
Embodiment 2:
On the basis of embodiment 1, cooler 9 takes back surge tank 1 again, forms a loop; Also be connected to hydrogen pipe 11 and nitrogen tube 10 on the surge tank 1; And be provided with sampling control valve 12 the import and export house steward.
Return in the surge tank 1 through subcooler 9 cooled gases.Respectively having sample point to analyze on the import and export house steward relatively imports and exports hydrogen content, controls and whether need add hydrogen.
The beneficial effect of present embodiment is: further improved the service efficiency of raw material, realized the recovery and reuse of reacting gas, economized on resources.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
