Abstract
The utility model proposes a kind of regenerative agent purification cooler, for oil catalyst reaction device.Is characterized in that being made up of the steam stripping unit three in one of the heat-obtaining unit at middle part, the carbonated drink separative element on top and bottom, have heat-obtaining, carbonated drink is separated, displace the triple functions of oxygen that catalyst carries and regenerated flue gas.
Description
Technical field
The utility model relates to a kind of regenerative agent purification cooler, is particularly applicable to the catalyst cleaning cooler of one of the control of catalyst in petroleum hydrocarbon or alcohols feedstock catalytic reaction and cooling catalyst, purification.
Background technology
In catalytic cracking and Methanol hydrocarbon products commercial plant, catalyst heat collector is often set, takes out the surplus heat of reaction or regenerative process, or reduce regenerative agent temperature, also usually cool regenerative agent with external warmer, then send into reactor.
Because catalyst flowing must have gas to make its fluidisation, the catalyst of external warmer carries certain oxygen and regenerated flue gas, and this part oxygen enters reactor and reaction medium reacts, and there is the oxygen entering reactor can affect product; The flue gas carried from regenerated catalyst strengthens rich gas press load, increases energy consumption.In methanol-to-olefins process, the flue gas that regenerative agent carries or oxygen affect the efficiency that product gas is separated, and need to prevent regenerative agent from carrying fixed gas and enter reactor; Reacted spent agent carries gas product, directly enters the burning of regenerative agent gas product, reduces the yield of gas product, need to prevent gas product from entering regenerator with catalyst circulation, generally arrange independently stripping section.
In addition, catalyst heat-obtaining is often used for steam occurs, and carbonated drink separation will be carried out in steam-water separator (also known as drum).Realize carbonated drink separation, often need to be connected with the drum away from external warmer with valve with a large amount of pipelines, cause heat loss strengthen and reduce the thermal efficiency, also add rolled steel dosage and investment; In addition, because drum is arranged on the high-altitude of more than 10 meters, need arrange corresponding drum framework platform and pipe support, occupation of land is many, and investment is large, and what have also needs electric energy to maintain normal water circulation, reduces reliability of operation.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly realizes catalyst heat-obtaining simultaneously and carry the equipment of gas cleaning, carries gas and carbonated drink is separated away from problems such as external warmers with the catalyst solved from external warmer.
For solving the problem, the technical solution adopted in the utility model is:
A kind of catalyst cleaning cooler, be made up of three parts: top arranges a steam-water separator, and middle part arranges catalyst heat collector, bottom directly arranges a stripper, realizes steam-water separator, the cooling of catalyst heat-obtaining, catalyst stripping three in one.A catalyst inlet pipe is set at catalyst cleaning cooler, one to three catalyst outlet pipe simultaneously.
To be catalyst cleaning cooler be made up of the heat-obtaining unit at middle part, the carbonated drink separative element on top, the steam stripping unit of bottom, catalyst inlet/outlet pipe concrete scheme.Heat-obtaining unit carries out heat-obtaining to gas-solid fluidized bed middle superfluous heat, steam water interface carries out carbonated drink separation at separative element, isolated steam is drawn stand-by by steam (vapor) outlet, steam stripping unit effectively can displace the gas that catalyst carries from regenerator or reactor, is drawn by gas vent.There is the catalyst of waste heat to enter heat-obtaining unit in the middle of catalyst cleaning cooler by catalyst inlet pipe in regenerator or reactor, lowered the temperature by heat-obtaining unit heat exchanger tube; In heat exchanger tube, gas-vapor mix enters top carbonated drink separative element and is separated; Catalyst after cooling enters the steam stripping unit of bottom, displaces the gas carried in catalyst, thus reaches the object of cooling catalyst, purification and control.Catalyst point one to three outlet after purification cooling is flowed out.
Regenerative agent purification cooler of the present utility model compared with prior art, has following beneficial effect:
1, catalyst heat-obtaining cooling, steam-water separator and stripper three in one, save space, pipeline layout, platform layout, occupation of land, valve etc., economize energy, convenient installation, operation.
2, the stripper of catalyst cleaning cooler bottom effectively can displace the gas in catalyst, thus reaches the object of regenerative agent purification.
3, the catalyst after cooling and purifying enters reactor or regenerator, realizes the circulation of catalyst.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is intended to help reader understanding's feature of the present utility model and essence, but the drawings and specific embodiments content do not limit of the present utility model can practical range.
As shown in Figure 1, the catalyst cleaning cooler of a kind of utility model, is made up of the steam stripping unit 3 of the heat-obtaining unit 2 at middle part, the carbonated drink separative element 1 on top and bottom.Catalyst enters heat-obtaining unit 2 in the middle of catalyst cleaning cooler by catalyst inlet pipe 4, is lowered the temperature by heat-obtaining unit 2 heat exchanger tube 21; In heat exchanger tube 21, gas-vapor mix enters top carbonated drink separative element 1 and is separated, and isolated steam is drawn stand-by by steam (vapor) outlet 11; Catalyst after cooling enters the steam stripping unit 3 of bottom, displaces in catalyst and carries gas, is drawn by gas vent 8, thus reaches the object to cooling catalyst, purification and control; Catalyst point 1 to 3 tunnel after purification controls is flowed out.
