Abstract
The utility model discloses a batch feeding pipeline with a cleaning function. The batch feeding pipeline comprises a batch feeding pipeline which is arranged above a reactor, wherein two valves are arranged on the batch feeding pipeline at an interval; an air inlet pipeline is connected to the batch feeding pipeline between the two valves; an adjusting valve is arranged on the air inlet pipeline. During the batch feeding process of powder, the pipeline is automatically cleaned; solid powder is prevented from being attached on the wall of the pipeline and a ball valve; the sealing face of the ball valve is well protected; and the problem that the pipeline is easily blocked is solved.
Description
Technical field
The utility model relates to solid powder commissioning pipe line technology field, especially relates to a kind of pipeline that feeds intake with cleaning function.
Background technology
As shown in Figure 2, existing when throwing solid powder in reactor 1, be all to adopt pipeline to carry powder, solid powder feeds intake through the pipeline 2 that feeds intake, and powder is easily attached on duct wall and ball valve, causes ball valve sealing face to damage and situation that the pipeline that feeds intake stops up.
Particularly the steam in reactor enters into the pipeline that feeds intake, and above-mentioned situation is more severe, and maintenance is inconvenience very, and maintenance cost is high; Meanwhile, on production efficiency impact greatly, perplexing technical staff always.
Utility model content
For prior art deficiency, technical problem to be solved in the utility model is to provide a kind of pipeline that feeds intake with cleaning function, and it can prevent that solid powder is attached on duct wall and ball valve.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pipeline that feeds intake with cleaning function, comprise the pipeline that feeds intake that is located at reactor top, on the described pipeline that feeds intake, be interval with two valves, the pipeline that feeds intake between described two valves is connected with admission line, and admission line is provided with control valve.
Further, the pipeline that feeds intake between described two valves is provided with pressure sensor.
Described control valve is electric control valve.
The utility model compared with prior art, has the following advantages:
1, the dry zoning in pipeline that feeds intake, effectively intercepts steam in reactor and enters powder;
2, automated cleaning pipeline in the process that powder feeds intake, prevents that solid powder is attached on duct wall and ball valve, better protects ball valve sealing face, solves the easy blockage problem of pipeline;
3, input cost is low, easy and simple to handle.
Accompanying drawing explanation
Below the mark in the each width accompanying drawing of this description expressed content and figure is briefly described:
Fig. 1 is the utility model commissioning pipe line structure schematic diagram.
Fig. 2 is existing commissioning pipe line structure schematic diagram.
In figure: 1. reactor, 2. feed intake pipeline, 3. ball valve II, 4. ball valve I, 5. pressure sensor, 6. admission line, 7. electric control valve.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, this has the pipeline that feeds intake of cleaning function, and this pipeline 2 that feeds intake is arranged on the top of reactor 1, and by feeding intake, pipeline 2 is delivered solid powder to reactor 1.
Setting up and down at the interval that feeds intake on pipeline 2 have two valves, two valves are ball valve, valve is up ball valve I 4, below valve be ball valve II 3, the pipeline 2 that feeds intake between ball valve I 4 and ball valve II 3 is connected with admission line 6 one end, admission line 6 other ends are connected with nitrogen pot, are provided with electric control valve 7 on admission line 6.
On the pipeline 2 that feeds intake between ball valve I 4 and ball valve II 3, be provided with pressure sensor 5, pressure sensor is connected with controller respectively with electric control valve.Can control nitrogen and be input to feeding intake in pipeline 2 between ball valve I and ball valve II, automatically regulate electric control valve to keep pressure according to setup pressure value.
The pressure that is kept above reactor 1 in the pipeline 2 that feeds intake between two valves, the steam in reactor can not enter into the pipeline that feeds intake, and the pipeline moment that makes to feed intake keeps dry state, and forms dry zoning.While feeding intake, commissioning pipe linear pressure can order about nitrogen in pipeline and enter fast reactor, reaches cleanser conduit object.In feeding intake, nitrogen keeps certain flow, enters reactor together with solid powder, has effectively intercepted steam and has entered in the powder feeding intake in pipeline.
The feeding method that utilizes the pipeline that feeds intake with cleaning function described above, comprises the following steps:
Ball valve I and ball valve II are in closed condition, utilize pressure sensor and motorized adjustment valve regulation nitrogen to enter into the pipeline that feeds intake, keep the force value in pipeline that feeds intake, stop the steam in reactor to enter into the pipeline that feeds intake, keeping ball valve II top and the pipeline middle and upper part that feeds intake is drying regime;
While feeding intake, first open ball valve II, and keep nitrogen to have certain flow, the nitrogen feeding intake in pipeline has the process of a purging to pipeline and ball valve II, reach cleanser conduit object;
Then, open ball valve I and feed intake, by the flow value of motorized adjustment valve regulation nitrogen, keep certain nitrogen to be blended in powder and enter reactor, the steam effectively intercepting in reactor enters in the powder feeding intake in pipeline;
Feed intake complete, operation electric control valve increases the nitrogen charge flow rate of admission line, and the pipeline of the pipeline that feeds intake is purged, and then closes two ball valves that feed intake on pipeline.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
