Abstract

The utility model provides an oil-fired vertical boiler with no leg ring, comprising boiler barrel which is provided with a water inlet pipe, a steam outlet pipe, a smoke box and a group of ear pipes. A boiler container is provided with a group of straight water pipes, and is connected and supported in the boiler barrel by a flame injecting pipe opening and a smoke uptake pipe. The utility model has the advantages that the traditional structure method of the existing vertical boiler of U-shaped foot rings being connected with the boiler container and the boiler barrel is not used; the production technology is simplified; the manufacture is convenient; the production cost is reduced; the scale prevention and the scale removal effects are better; the smoke dust pollution is not provided; the utility model is especially suitable for creating sanitary cities and landscape traveling areas.

Description

The vertical non foot ring boiler of fuel oil

The utility model relates to steam boiler, and the vertical non foot ring boiler of specifically a kind of fuel oil is specially adapted to promote the use of in Scenic Spot Area and the area of building a nationally advanced clean city.

At present; generally be used in organ; the vertical fire coal steam boiler of industrial and mining enterprises; its disadvantage is exactly: smoke discharge amount is big in the course of the work; serious environment pollution; though the coal-burning boiler that has has adopted the smoke abatement and dust control measure; but still be difficult to reach the waste gas emission standard of national regulation; for preserving the ecological environment conscientiously; degree effectively alleviates air pollution; environmental administration requires to promote the use of clean hygiene at Scenic Spot Area and city, down town; the oil burning boiler of no smoke contamination; the common oil burning boiler of having finalized the design generally is dried now; the wet back of the body is horizontal; this oil burning boiler structure is comparatively complicated; the installation floor space is big; certain limitation is arranged in the use; the recent vertical oil burning boiler of releasing; it is mainly by shell; flue; be installed on the bright eruption mouth of pipe of shell; smoke box and one group of curved ear duct constitute; it between shell and the flue structural shape that adopts traditional U type pin circle to connect; though this vertical oil burning boiler has clean hygiene; no smoke contamination; install and take up an area of advantages such as little; but: the U type pin circle that connects flue and shell generally needs the punching press of large-tonnage forcing press to make; because diel complex structure; the molding expense is higher; complex manufacturing; manufacture difficulty is bigger; the production cost height; so this boiler price is higher, directly effect is promoted the use of in influence.

The purpose of this utility model be on the prior art basis, propose a kind of simple in structure, easy to manufacture, production cost is lower and the vertical non foot ring boiler of fuel oil of better tartar preventing iron tartar effect is arranged.

The purpose of this utility model is achieved by the following technical solution.

The vertical non foot ring boiler of a kind of fuel oil, it mainly is made of the drum that is installed on leg, the water inlet pipe that is installed on drum, steam outlet pipe, smoke box and one group of curved ear duct, smoke box is installed on the uptake tube exit, place one group of curved ear duct in the smoke box to communicate with drum, flue is connected with uptake tube by the bright eruption mouth of pipe and is supported in the drum, and one group of straight-through water pipe is installed in flue.

Characteristics of the present utility model are: the flue that one group of straight-through water pipe is installed is connected with uptake tube by the bright eruption mouth of pipe and is supported in the drum, having abandoned existing vertical boiler adopts U type pin circle to connect the traditional structure mode of flue and drum, simplified production technology, make more easy, greatly reduce production costs, no smoke contamination has tartar preventing iron tartar effect preferably.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is A-A cutaway view of Fig. 1.

The utility model will be further described below in conjunction with accompanying drawing: the vertical non foot ring boiler of a kind of fuel oil, it is mainly by the drum 1 that is installed on leg 6, be installed on the water inlet pipe 7 of drum 1, steam outlet pipe 11, smoke box 3 and one group of curved ear duct 4 constitute, smoke box 3 is installed on uptake tube 5 exits, above smoke box 3, done exhaust opening 2, can be connected and installed chimney on the exhaust opening 2, place one group of curved ear duct 4 in the smoke box 3 to communicate with drum 1, flue 9 is connected with uptake tube 5 by the bright eruption mouth of pipe 10 and is supported in the drum 1, one group of straight-through water pipe 8 is installed in flue 9, combustor is connected and installed in the bright eruption mouth of pipe 10, fuel oil is imported in the flue 9 by the bright eruption mouth of pipe 10 at the heat of combustor internal combustion, one group of straight-through water pipe 8 of heating flue 9 and Qi Nei, thereby the water in the heating drum 1, the steam that produces is by steam outlet pipe 11 output steam supplies, the flue gas of burning imports smoke box 3 by uptake tube 5, discharge by exhaust opening 2, remaining heat is absorbed by the one group of curved ear duct 4 that communicates with drum 1, make full use of flue gas heat, can further improve heat utilization efficiency and steam generating capacity, on drum 1 and flue 9 all adopt, the structural shape that low head connects, but simplified manufacturing technique, reduce production costs, done manhole 12 at the top of drum 1, used for the maintenance boiler.
