Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described:

[0012] Such as figure 1 , figure 2 As shown, a chimney head automatic ice device and ice melting method thereof, a steel needle 2 is arranged on the top of the chimney 1 head, the steel needle 2 is fixed on the top of the chimney 1 by bolts 8, and the inner circumference of the inner pipe top of the chimney 1 is arranged There is a heating main pipe 3, and an ice-melting pipe 4 is arranged on the outside of the top of the chimney 1. The heating main pipe 3 and the ice-melting pipe 4 are connected by a connecting pipe 5. The outer surface of the cylinder head 1 is provided with a polymer of fluorosilane and methacrylic acid to form a hydrophobic Layer 6. In the present invention, a steel needle 2 is arranged on the top of the chimney 1. Due to the high-altitude environment, the random wind speed will not be small. An appropriate steel needle is installed on the top of the chi...

Abstract

The invention relates to an automatic deicing device of a barrel head of a chimney and a deicing method thereof. The device comprises steel needles which are arranged on the top portion of the barrel head of the chimney, a main heating pipe which is arranged on the periphery of the inner side of the top portion of an inner barrel of the chimney and a deicing pipe which is arranged outside the top portion of the chimney. A water drainage layer is further arranged on the outer surface of the barrel head. According to the device, the steel needles are arranged on the barrel head of the chimney, small ice particles which are possible to be formed are shaken off by shaking of the steel needles under the action of the wind, automatic venting heat exchanging and deicing devices are arranged inside and outside the barrel head and matched with the water drainage layer of the outer surface of the barrel head, so that the freezing problem of the barrel head can be solved effectively.

Description

technical field [0001] The invention relates to an automatic ice device at the head of a chimney and an ice melting method thereof. Background technique [0002] The flue gas from wet desulfurization, due to the high humidity in the chimney head area, will condense and form ice at the chimney head in cold regions. Accidents of ice cubes falling and hurting people frequently occur at the chimney head, affecting people's normal life and life safety. Preventing the icing of the cylinder head is an urgent problem to be solved, and it is also a difficult problem to solve. It is related to various aspects such as meteorological conditions, operation mode, and antifreeze facilities. At present, no relevant units have adopted suitable anti-freezing measures. Some people go up to the chimney head to knock off the ice with a hammer after the head of the chimney is frozen. Manual deicing is very unsafe and inconvenient. It is essential for people's safety management to adopt effective...
