Abstract
The utility model relates to a reactor for testing the coke reactivity, in particular to a protective device for preventing a reactor from oxidating and spalling. The protective device for preventing the reactor from oxidating and spalling comprises the reactor, meanwhile, the characteristics are as follows: the reactor is movable installed in a protective box with an interlayer, and the interlayer is provided with a cooling circulating water pipe, and the bottom of the protective box is provided with a hole. The bottom layer of the protective box is fixed with a bracket. The protective device provided by the utility model has advantages of simple structure, fast cooling speed, and can slow the phenomenon of reactor-surface spalling, and can extend the service life of the reactor, and can reduce the cost of equipment.
Description
Technical field
The utility model relates to a kind of reactor of testing coke reactivity, specifically a kind of protective device that prevents reactor oxidation decortication.
Background technology
When STRENGTH ON COKE is carried out reactivity and post reaction strength test, in test procedure, illustrate among the GB/T4000 " coke reactivity and post reaction strength test method ": coke 1100 ℃ with carbon dioxide reaction after 2 hours, rapidly the steel alloy reactor is taken out from electric furnace, be placed on and continue logical nitrogen on the support, coke is cooled off.So the purpose of operation is in order to add the cooling of coke specimen behind the fast response, to shorten the entire test required time.
When in the test reactor being taken out from electric furnace is to take out from electric furnace under near 1100 ℃ the condition of high temperature, practice as seen, because this is subjected to high-temperature oxydation easily the steel alloy reactor material in air, make the reactor surface decortication and trachoma occurs, reactor wall thickness attenuate, impaired destruction is serious, causes reactor can not continue to use, and often needs to change new reactor.Therefore invent a kind of protective device of reactor, be highly profitable with life-span of extension reactor.
Summary of the invention
The purpose of this utility model is exactly the defective at prior art, provides a kind of protective device that prevents reactor oxidation decortication, to remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises reactor, is characterized in that: the reactor activity is contained in the guard box that has an interlayer, and the cool cycles water pipe is housed on the interlayer, and the bottom of guard box has the hole.Described guard box bottom is fixed with support.
The utlity model has advantage simple in structure, that cooling velocity is fast, it can make reactor surface decortication phenomenon slow down greatly, extension reactor service life, reduces the cost of equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
As shown in Figure 1; the utility model comprises reactor 2; reactor 2 activities are contained in the guard box 1 that has an interlayer 7; cool cycles water pipe 4 is housed on the interlayer 7; dress cooling circulating water in the interlayer; the bottom of guard box 1 has the hole, and the nitrogen air inlet pipe 3 of reactor 2 is passed the hole and extend into the outer nitrogen of being convenient to of guard box 1 and feed.The size in hole makes around the nitrogen air inlet pipe slightly slit, and certain release of pressure effect can be arranged the gas in the case, can take heat out of simultaneously.Described guard box bottom is fixed with support 5.The top of guard box is provided with top cover 6.
Claims (2)
1. protective device that prevents reactor oxidation decortication, it comprises reactor, it is characterized in that: the reactor activity is contained in the guard box that has an interlayer, and the cool cycles water pipe is housed on the interlayer, and the bottom of guard box has the hole.
2. a kind of protective device that prevents reactor oxidation decortication according to claim 1, it is characterized in that: described guard box bottom is fixed with support.
