Abstract
The utility model relates to the cooling field of boilers and particularly relates to a cooling device for use at an exit of a high-temperature cyclone separator of a circulating fluidized bed boiler. The water-cooling central air outlet cylinder comprises a water inlet collection tank and a water outlet collection tank, wherein the water inlet collection tank is connected with a water inlet tube joint, the water outlet collection tank is connected with a water outlet tube joint, the water inlet collection tank and the water outlet collection tank are communicated with each other through a tube, flat steels are arranged on two sides of the outer wall of the tube and are connected through a pin bolt to form a tube panel, and the tube panel and the pin bolt are covered by pouring materials. According to the water-cooling central air outlet cylinder of the cyclone separator, the structure is simple, and the service life is long; and the material is saved, and the cost of the boiler is lowered.
Description
Technical field
The utility model relates to a kind of boiler cooling field, particularly relates to a kind of cooling device for the high-temperature cyclone separator of circulating fluid bed exit.
Background technology
in the prior art, the center gas outlet of cyclone separator of circulating fluidized bed boiler outlet adopts the thermalloy steel making, because the high-temperature flue gas that will bear 1000 ℃ washes away, and contain corrosive gas in flue gas and be easy to produce wear particle, the center gas outlet is easy to damage distortion or serious wear, service life is generally in 2 ~ 3 years, well damage not even over 1 year, after the center gas outlet damages, the boiler shutdown maintenance of having to, be in simultaneously the top of boiler due to the center gas outlet, it is again key position, cause that more switching center9's gas outlet is very difficult, when changing, the material of center gas outlet itself is high-quality thermalloy steel, price is very expensive, approximately 130,000 yuan of 75t/h CFBB center gas outlets, production cost and input to enterprise have caused very large expense.
The utility model content
The utility model provides a kind of simple in structure in order to address the above problem, long service life, economical with materials and reduce the cyclone separator water-cooled center gas outlet of boiler cost.
A kind of cyclone separator water-cooled center gas outlet, contain into water header, water outlet header, described water inlet header is connected with admitting pipe joint, the water outlet header is connected with titting water outlet, be connected by pipe between water inlet header and water outlet header, the outer wall both sides of described pipe are provided with band steel, connect by pin between band steel and form tube panel, are coated with castable on described tube panel and pin.
Described pin is fixed by welding on band steel.
Described admitting pipe joint is located at into the bottom of water header, and described titting water outlet is located at the top of water outlet header.
Useful good effect of the present utility model is:
The utility model is simple in structure, because water is connected with boiler steam and water circuit, cooling pipe in the water flowing pipe, tube panel can use for a long time, and tube panel is coated with the plastic castable of fire-resistant abrasion-proof outward simultaneously, and when making boiler operatiopn, cylindrical shell high temperature corrosion and coking can not occur, cause the damage distortion of cylindrical shell, cyclone separator water-cooled of the present utility model center gas outlet long service life, and production cost is low, a 75t/h CFBB center gas outlet can be saved 80,000 yuan.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross sectional representation of pipe in the utility model;
Fig. 3 is the local enlarged diagram of Ι section in Fig. 2.
The specific embodiment
Referring to Fig. 1 ~ shown in Figure 3, the meaning of number in the figure representative is: 1 admitting pipe joint, 2 water inlet headers, 3 titting water outlets, 4 water outlet headers, 5 pipes, 6 band steels, 7 pins, 8 castables.
The utility model in use, admitting pipe joint 1 is connected with water inlet header 2, titting water outlet 3 is connected with water outlet header 4, water outlet header and water inlet header are connected by pipe 5, the outer wall both sides of pipe are provided with band steel, being welded with pin 7 on band steel 6 becomes one, on the tube panel and pin 7 of the plastic castable cast of fire-resistant abrasion-proof, during work, current enter pipe 5 through admitting pipe joint 1 through the water inlet header, again from water outlet header 4 through after titting water outlets 3, enter drum by pipeline, thereby form cyclone separator water-cooled center gas outlet.
