Be connected through cooling jacket between burner and the cooler;
Be provided with choke valve between cooler and the burner chilled water tank;
Be provided with check (non-return) valve between pressure pump and the accident burner chilled water tank;
Accident burner chilled water tank is connected through cooling jacket with burner.
Between said check (non-return) valve and the accident burner chilled water tank, also be provided with flow control valve; Simultaneously, the cooling jacket between accident burner chilled water tank and the burner is provided with flowmeter, and flowmeter links to each other with flow control valve.
Said accident burner chilled water tank also is connected with nitrogen cylinder, and nitrogen cylinder is used to import nitrogen, and accident burner chilled water tank and nitrogen cylinder are connected with the valve of control input nitrogen.When power outage takes place, or in reserve pump starts blanking time, open valve, high pressure nitrogen charges into accident burner chilled water tank, guarantees that the cooling of burner is remained valid, and guarantees ordinary production.
Operation principle of the present invention is following:
At first be that the interior cooling water of burner chilled water tank is forced into required pressure through pressure pump; Directly get into the accident burner chilled water tank of high point then; Liquid level through cooling water in the flow control valve assurance accident burner chilled water tank; Cooling water is prepared burner is cooled off through the cooling jacket of accident burner chilled water tank entering burner then; After burner was cooled, cooling water left cooling jacket and gets into cooler, behind choke valve, is admitted to the burner chilled water tank, and circulation goes round and begins again.
When normal operation, for guaranteeing the cooling water temperature and the pressure stability of turnover burner, on cooling jacket, be provided with the pressure and temperature sensor, in the time of can monitoring the hypotony in the cooling jacket that gets into burner at any time, start subsequent use pressure pump.
Said cooling water can be a desalted water.
The invention has the beneficial effects as follows:
When cooling water system job insecurity state, the present invention can guarantee the operate as normal of accident chilled water tank, and the cooling of burner is remained valid, and has increased the reliability of whole system; Particularly start in blanking time at generation power outage or reserve pump; Valve open, high pressure nitrogen charge into accident burner chilled water tank, guarantee that burner cooling system manifold pressure is greater than gasification furnace pressure; The cooling of guaranteeing burner is remained valid, and guarantees ordinary production; In addition, the minimizing of valve and number of tubes has also reduced the maintaining cost.
