Abstract

Disclosed is a water-fire pipe type boiler with the smoke pipe protector, in particular to a water-fire pipe type boiler with the smoke pipe protector, comprising a boiler body (1) and a metal sleeve protection pipe with abrasion resistance. The pipe opening of one end of the metal sleeve protection pipe (2) with abrasion resistance is outward folded a ring of short edges (2-1); the other end pipe wall of the metal sleeve protection pipe (2) with abrasion resistance is opened with a gap (2-2) whose open direction is parallel to the center of circle wire of the metal sleeve protection pipe (2) with abrasion resistance; the outer wall of the metal sleeve protection pipe (2) with abrasion resistance is sheathed in the inner wall at the air intake end port position of the left end of the smoke pipe (1-1) of the boiler body; the right side surfaces of the short edges (2-1) on the metal sleeve protection pipe (2) with abrasion resistance is contacted with the end surface of the air inlet port at the left of the smoke pipe (1-1). The utility model can protect the surface at the air inlet port of the smoke pipe (1-1) from the abrasion of the high temperature smoke, and has the advantages of simple structure, low cost and easy maintenance.

Description

The extreme misery tubular boiler of band smoke pipe protective device

Technical field:

The utility model relates to the extreme misery tubular boiler, specifically is a kind of extreme misery tubular boiler with the smoke pipe protective device.

Background technology:

Advantages such as it is fast that existing extreme misery tubular boiler has the temperature of giving birth to, and heat-transfer effect is good.But when fuel quality, when bigger variation takes place the flue gas actual internal area, exist smoke pipe air inlet port to be subject to the wearing and tearing of high-temperature flue gas, increased maintenance cost, can not guarantee the drawback of the safe and continuous operation of boiler to the user.

The utility model content:

The purpose of this utility model provides a kind of extreme misery tubular boiler with the smoke pipe protective device.The utility model is when operation, and the air inlet port of smoke pipe can not be subjected to the wearing and tearing of high-temperature flue gas.The utility model comprises boiler body 1, and it also comprises abrasionproof protective metal shell pipe 2; The length of abrasionproof protective metal shell pipe 2 is 1.5～5 times of himself diameter, the one end mouth of pipe of abrasionproof protective metal shell pipe 2 has a circle minor face 2-1 to turning up, the length of minor face 2-1 is 2～8mm, have slit 2-2 on the tube wall of abrasionproof protective metal shell pipe 2 other ends, the direction of offering of slit 2-2 parallels with the center of circle line of abrasionproof protective metal shell pipe 2, and the length of slit 2-2 is less than 4/5ths of abrasionproof protective metal shell pipe 2 length; The outer wall of abrasionproof protective metal shell pipe 2 is socketed in the inwall of the smoke pipe 1-1 left end air inlet port in the boiler body 1, and the minor face 2-1 right flank on the abrasionproof protective metal shell pipe 2 is contacted with the end face of smoke pipe 1-1 left end air inlet port.The surface that the utility model can be isolated the smoke pipe 1-1 air inlet port in high-temperature flue gas and the boiler body 1 contacts, and makes the surface of smoke pipe 1-1 air inlet port not be subjected to the wearing and tearing of high-temperature flue gas, and have simple in structure, cost is low, the advantage of easy care.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is the structural representation of abrasionproof protective metal shell pipe 2, and Fig. 3 is the A-A cutaway view of Fig. 2.

The specific embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3 present embodiment is described, present embodiment is made up of boiler body 1, abrasionproof protective metal shell pipe 2; The length of abrasionproof protective metal shell pipe 2 is 1.5～5 times of himself diameter, the one end mouth of pipe of abrasionproof protective metal shell pipe 2 has a circle minor face 2-1 to turning up, the length of minor face 2-1 is 2～8mm, have slit 2-2 on the tube wall of abrasionproof protective metal shell pipe 2 other ends, the direction of offering of slit 2-2 parallels with the center of circle line of abrasionproof protective metal shell pipe 2, and the length of slit 2-2 is less than 4/5ths of abrasionproof protective metal shell pipe 2 length; The outer wall of abrasionproof protective metal shell pipe 2 is socketed in the inwall of the smoke pipe 1-1 left end air inlet port in the boiler body 1, and the minor face 2-1 right flank on the abrasionproof protective metal shell pipe 2 is contacted with the end face of smoke pipe 1-1 left end air inlet port.
