Abstract

The utility model relates to a boiler with rotatory firearm of crossing, including gasification combustion chamber, burn out room and smoke box, burn out the room and be located gasification combustion chamber below, the rotatory fire ware of crossing that gasification combustion chamber placed through the slope connects the smoke box. High temperature flue gas and the particulate matter of not fully burning of combustion chamber on the one hand get into the rotation with the vertical direction and cross the firearm in, high temperature flue gas and the particulate matter of not fully burning form rotatory air current in the ware is crossed in the rotation, and when the rotatory air current of high temperature got into first smoke box, with the air intensive mixing, the flue gas forms the flue gas circulation in first smoke box of going up, and the high temperature flue gas realizes smokeless co-combustion from this. On the other hand, due to the blocking effect of the over-fire pipe wall, larger particles which are not fully combusted in the boiler collide at high speed and stay on the pipe wall, few pollution particles in the air flow entering the heating threaded smoke pipe are few, and the insufficient combustion smoke generated in the combustion chamber is greatly consumed due to the mixed combustion effect generated by smoke circulation.

Description

Boiler with rotary fire-crossing device

Technical Field

The utility model relates to a civil boiler stove field especially relates to a boiler with rotatory fire ware of crossing.

Background

In recent years, with the continuous deterioration of air quality, air pollution control becomes a focus of public attention, and various governments are thinking and trying to take various measures to control air pollution. The development report 2016 of the Chinese heating stove industry shows that 77% of residents still use low-efficiency inferior stoves and use inferior loose coal in winter heating in rural areas of China, so that the atmospheric pollution is very serious. In recent years, the countries begin to popularize and implement the project of 'changing electricity from coal to electricity and changing gas from coal to gas' in partial areas, but some safety and economic problems are also exposed. Therefore, the development of key technologies and product development projects for civil heating bulk coal combustion pollution treatment is urgent, and the method is an important measure for treating haze and severely controlling bulk coal pollution. According to the deployment of the Shanxi coal chemical group, a CWGGO.12-85/60-J intelligent energy-saving environment-friendly boiler is researched and developed vigorously, and the pollution-control and haze-reduction industry of green Shanxi coal is created to the utmost extent by relying on high-quality coal resources in the Shanxi of the Shanxi coal chemical group.

The CWGO.12-85/60-J intelligent energy-saving environment-friendly boiler is an efficient, energy-saving and environment-friendly boiler, has been developed into a series of boilers with the power of 0.05-0.35MW, the calorific value of 40000-.

The intelligent energy-saving environment-friendly boiler CWGO.12-85/60-J extracts heat required by domestic water from the heated hearth. The heat energy generated in the hearth heats the water in the water tank, and then the water is led into the buffer heat accumulator or the radiator at the temperature level of about 85 ℃. The water tank is connected with a heating air return system. The return water is extracted for heating and re-fed into the heating return system.

The traditional boiler lower combustion type primary air inlet furnace burns from bottom to top, because the temperature of the upper part of a coal bed and a combustion chamber is low, and the return distance of flue gas is short, a lot of combustible gas can not be fully burnt, smoke particles are formed and run out, and therefore the heat loss is large, the heat efficiency is low, energy is wasted, and the environment is polluted.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention has been made to provide a boiler with a rotary transition burner that overcomes or at least partially solves the above problems.

According to the utility model discloses an aspect provides a boiler with rotatory fire ware of crossing, including gasification combustion chamber, burn out room and smoke box, burn out the room and be located gasification combustion chamber below, the rotatory fire ware of crossing that gasification combustion chamber placed through the slope connects the smoke box.

In a possible implementation mode, the smoke box comprises a first upper smoke box, a first lower smoke box located below the first upper smoke box, a second upper smoke box and a second lower smoke box located below the second upper smoke box, the gasification combustion chamber is connected with the first upper smoke box through a rotary fire passing device placed obliquely, the first upper smoke box is connected with the first lower smoke box through a first group of heating threaded smoke pipes, the first lower smoke box is connected with the second upper smoke box through a second group of heating threaded smoke pipes, and the second upper smoke box is connected with the second lower smoke box through a third group of heating threaded smoke pipes.

In a possible embodiment, the second upper smoke box is also provided with a head hole explosion-proof valve.

In one possible embodiment, the first upper smoke box is provided with an ash removal door.

The utility model has the advantages that:

high temperature flue gas and the particulate matter of insufficient combustion of combustion chamber get into rotatory firearm (being fire tube) with the vertical direction on the one hand, because the slope of rotatory firearm in the boiler is placed, make high temperature flue gas and the particulate matter of insufficient combustion collide the turn to many times at the pipe wall after getting into fire tube, the primary air that the boiler fan sent into in addition, high temperature flue gas and the particulate matter of insufficient combustion form rotatory air current in rotatory firearm, when the rotatory air current of high temperature gets into first upper smoke box, with the air intensive mixing, the flue gas forms the flue gas circulation in first upper smoke box, high temperature flue gas realizes smokeless co-combustion from this. On the other hand, due to the blocking effect of the over-fire pipe wall, larger particles which are not fully combusted in the boiler collide with the pipe wall at a high speed and are left in the first upper smoke box 6, few pollution particles in air flow entering the heating threaded smoke pipe are generated, in addition, the mixed combustion effect generated by smoke circulation greatly consumes the flue gas which is not fully combusted in the combustion chamber, the air heat flow discharged into the atmosphere reaches the national atmospheric emission standard of boiler combustion, the air pollution is reduced, the environment is protected, and the effect is remarkable.

The above description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the present invention is given.
