Abstract
The invention discloses a cooling device of a plasmas cathode subassembly. The cooling device comprises a cathode shell and a cathode which is internally arranged inside the cathode shell; a water cooling annular groove is machined on the inner wall surface of the cathode shell; two ends of the cathode are respectively connected with liquid corresponding to flanges at upper and lower two sides of the water cooling annular groove in a sealing manner; a space between the cathode and the water cooling annular groove is provided with a cathode water jacket so that the space is divided into a cooling water input chamber and a cooling water output chamber which are communicated with each other; one end of the cathode water jacket is in a threaded connection with the water cooling annular groove and the other end of the cathode water jacket is movably arranged; the cathode shell is respectively and correspondingly provided with a water inlet which is communicated with the cooling water input chamber and a water outlet which is communicated with the cooling water output chamber. Therefore, the cooling device can solve the problems that the service of the traditional plasma igniting cathode is short and the consumption amount of the cooling water is great.
Description
Technical field
The present invention relates to a kind of cooling structure device, especially a kind of cooling device of plasma cathode assembly.
Background technology
Data shows that annual power station is used for igniting, surely fires and helps approximately nearly ten million ton of fuel oil, accounts for 15% of the total amount of fuel in the whole nation; Utility boiler plasma non-oil ignition technology is a kind of New-type boiler ignition technology; All obtained application in a lot of power plant at present, this technology both can have been saved valuable petroleum resources, improved fuel availability; And can reduce at coal and oil some problem of environmental pollutions in combustion process, for the energy security of country very big meaning is arranged.
As everyone knows, because the plasma-arc temperature is very high, electrode is in use ablated seriously; Life-span is short, has restricted the popularization of this technology to a great extent, at present; Both at home and abroad mostly prolong electrode useful life of negative electrode particularly through the material of seeking high heat conduction, high conduction, being difficult for oxidation, these materials all are expensive metal alloys, and a kind of in addition method is used the water quench negative electrode exactly; Reduce the ablation of electrode; This also is the many cooling meanss that adopt at present, but cooling effect is not good and consumption of cooling-water is excessive, and single plasma torch water consumption is at 10t/h.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of cooling device of plasma cathode assembly is provided, can solve the problem that present plasma ignition negative electrode useful life is short, consumption of cooling-water is big.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of cooling device of plasma cathode assembly, the negative electrode that comprises cathode shell and be built in cathode shell, the internal face of cathode shell is processed with the water-cooled cannelure; The two ends of negative electrode respectively with the water-cooled cannelure up and down both sides flange accordingly liquid sealing be connected; Negative electrode is separated into cooling water intake chamber and the cooling water water-supplying chamber that is communicated with space between the water-cooled cannelure through the negative electrode water jacket is set; And an end of negative electrode water jacket is threaded with the water-cooled cannelure, and the other end is then movable to be provided with; And offer the water inlet that is communicated with the cooling water intake chamber, the delivery port that is communicated with cooling water water-supplying chamber on the cathode shell respectively accordingly.
Said water inlet and delivery port all are provided with the internal face tangential of cathode shell.
Negative electrode upper shell and negative electrode lower house are arranged in said cathode shell split, and negative electrode upper shell and negative electrode lower house are integrally welded through argon arc welding; Delivery port is opened in the negative electrode lower house, and water inlet then is opened in the negative electrode upper shell, and negative electrode is threaded with the negative electrode upper shell.
According to above technical scheme, can realize following beneficial effect:
1, the present invention so that intake chamber and water-supplying chamber are separated, can improve cooling effect through adopting cooling jacket effectively, helps the even inflow and the discharge of cooling water; Consumption of cooling-water of the present invention is 6t/h, the conserve water resource; Simultaneously, the present invention has improved the useful life of negative electrode greatly, has reached 3000 hours; Reduced the length of negative electrode, economy strengthens.
