Abstract
The utility model is practical to be related to a kind of novel cracking still catalyst feeding device, including catalyst carrier, catalyst storage tank, catalyst dashpot, catalyst charging spout, cracking still, catalyst carrier is connect through dnockout pumps with catalyst storage tank, catalyst storage tank is connect through conveyance conduit with catalyst dashpot, and catalyst dashpot is connect through conveyance conduit with catalyst charging spout, and catalyst charging spout is connect through conveyance conduit with cracking still.Catalyst dashpot is connect through overflow pipe with catalyst carrier.When adding catalyst, catalyst is turned to catalyst storage tank by catalyst dnockout pumps, catalyst is put to catalyst dashpot by valve, then catalyst is put to catalyst charging spout by valve, finally completes feeding intake for catalyst.During blowing, catalyst storage tank and catalyst dashpot are equipped with overflow pipe, and extra catalyst returns to catalyst carrier by overflow pipe, improve the safety during charging.
Description
Technical field
The utility model is practical to be related to a kind of cracking still catalyst feeding device, belongs to field of chemical equipment.
Background technique
Diformazan hydrolysate is exactly carried out cracking rearrangement reaction by cracking process under the conditions of basic catalyst, contains D4 to be made
80% or so, the lysate of D3 5% or so and D5 15% or so.Cracking common basic catalyst is potassium hydroxide, due to reaction
The particularity of condition and equipment, continuous reinforcing body potassium hydroxide direct in cracking still can not achieve, so being typically all by hydrogen
Potassium oxide is configured to certain density solution, is then added in cracking still.The number of additional amount directly determines that cracking still is anti-
The height of efficiency is answered, and onium hydroxide solution has certain corrosivity, it is hidden with certain safety at the scene in operating process
Suffer from.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of cracking still catalyst feeding device, the feeding device
Including catalyst carrier, catalyst storage tank, catalyst dashpot, catalyst charging spout, cracking still, catalyst carrier is through dnockout pumps
It is connect with catalyst storage tank, catalyst storage tank is connect through conveyance conduit with catalyst dashpot, and catalyst dashpot is through delivery pipe
Road is connect with catalyst charging spout, and catalyst charging spout is connect through conveyance conduit with cracking still.
The catalyst dashpot is connect through overflow pipe with catalyst carrier.
The catalyst storage tank is connect through overflow pipe with catalyst carrier, is provided with liquidometer on catalyst storage tank.
Cracking still cracking reaction needs basic catalyst to be catalyzed, predominantly potassium hydroxide solution, concentration 40%-60%, tool
There is stronger corrosivity.When adding catalyst, catalyst is turned to catalyst storage tank by catalyst dnockout pumps, will be urged by valve
Agent is put to catalyst dashpot, then catalyst is put to the throwing that catalyst is finally completed to catalyst charging spout by valve
Material.During blowing, catalyst storage tank and catalyst dashpot are equipped with overflow pipe, and extra catalyst is by overflowing
Flow tube road returns to catalyst carrier, improves the safety during charging.The catalyst storage tank is equipped with remote liquid level
Meter and catalyst overflow pipe, it is ensured that storage tank level stability, safety.
The beneficial effects of the utility model are: catalyst during charging, by accurately Liquid level, ensure that
Feeding quantity is accurate, and for live employee during charging, whole process does not reach potassium hydroxide solution, ensure that the safety of operation
Property.
Detailed description of the invention
Fig. 1 is the schematic diagram of cracking still catalyst feeding device.
In Fig. 1,1. catalyst carriers, 2. dnockout pumps, 3. catalyst storage tanks, 4. catalyst dashpots, the charging of 5. catalyst
Slot, 6. liquidometers, 7. overflow pipes, 8. storage tank emptying pipelines, 9. conveyance conduits, 10. cracking stills.
Specific embodiment
A kind of cracking still catalyst feeding device, including catalyst carrier 1, catalyst storage tank 3, catalyst dashpot 4 are urged
Agent charging spout 5, cracking still 10, catalyst carrier 1 are connect through dnockout pumps 2 with catalyst storage tank 3, and catalyst storage tank 3 is through conveying
Pipeline is connect with catalyst dashpot 4, and catalyst dashpot 4 is connect through conveyance conduit with catalyst charging spout 5, catalyst charging
Slot 5 is connect through conveyance conduit with cracking still 10.
Catalyst dashpot 4 is connect through overflow pipe with catalyst carrier 1.
Catalyst storage tank 3 is connect through overflow pipe with catalyst carrier 1, is provided with liquidometer on catalyst storage tank 3.
In conjunction with Fig. 1, the catalyst in catalyst carrier 1 enters catalyst storage tank 3 by conveyance conduit 9 by dnockout pumps 2, urges
Catalyst in agent storage tank 3 enters catalyst dashpot 4 by conveyance conduit 9, and the catalyst in catalyst dashpot 4 is by conveying
Pipeline 9 enters catalyst charging spout 5, and the catalyst in catalyst charging spout 5 enters cracking still 10 by conveyance conduit 9.To guarantee
3 level stability of catalyst storage tank, safety are equipped with liquidometer 6, overflow pipe 7 and exhausting pipeline 8, to prevent catalyst from buffering
4 catalyst of slot overflows, and is equipped with overflow pipe 7.
The catalyst storage tank and catalyst dashpot are equipped with catalyst overflow pipe, during charging, effectively keep away
Exempt from the operating accident outside catalyst spilling slot, improves operational safety.
