Problems solved by technology

[0005] 3. The valve disc and valve stem in the intake valve adopt an integral design, and the valve disc, valve disc and valve seat form a rigid contact. When the valve stem is lifted upwards, the valve disc and valve seat are not matched precisely, which is easy to cause leakage
[0006] 4. The pressure of the steam outlet in the intake valve cannot be adjusted

Abstract

The invention relates to a long telescopic soot blower used for removing soot and slag on the surfaces of heating furnaces in the petrochemical industry, heating furnaces in the power industry, and the like. The soot blower comprises a box body (4), a moving cart (3), an outer soot blowing pipe (5), an inner blowing pipe (12), a steam inlet valve (1) and an operation mechanism (2), wherein the moving cart (3) comprises an electromotor (303) and a double-output-shaft speed reducer (304); the other output shaft of the double-output-shaft speed reducer (304) is provided with a main driving disk (305) and a speed reducer chain wheel (306); the main driving disk (305) is provided with a semicircular annular slot (309), and a pin (308) is embedded in the slot (309) and fixedly connected with the speed reducer chain wheel (306); the outer soot blowing pipe (5) is horizontally arranged in the box body (4), and the outer edge of the outer soot blowing pipe (5) is provided with a soot blowing pipe chain wheel (501); and the soot blowing pipe chain wheel (501) is connected with the speed reducer chain wheel (306) through a chain. In the invention, the outer soot blowing pipe has no blowing dead angles; the pressure of fillers in a filler box is stable; the matching in the steam inlet valve is precise; and the pressure of a steam outlet can be regulated.

Description

(1) Technical field [0001] The invention relates to a soot blower. It is used to remove dust and slag from the surfaces of heating furnaces in the petrochemical industry, heating furnaces in the power industry, convection tube bundles on boilers, air preheaters, and economizer superheaters. It belongs to the technical field of petrochemical and electric power equipment. (2) Background technology [0002] In heating furnaces in the petrochemical industry, heating furnaces in the power industry, convection tube bundles on boilers, air preheaters, economizer superheaters, etc., sootblowers are generally used to remove dust and slag from their surfaces to reduce The exhaust gas temperature is used to improve the thermal efficiency of heating furnaces and boilers to achieve the purpose of reducing consumption and saving energy. When the smoke temperature in the furnace exceeds 550°C, a long telescopic soot blower should be used. When the sootblower is blowing soot, it makes a ...
