Description

Semi-coke boiler

Technical Field

The utility model belongs to the technical field of the heat exchange, concretely relates to boiler suitable for burning blue charcoal carries out the heat exchange.

Background

The existing boiler grate is a cast iron grate, and is low in heat bearing capacity, the cast iron grate cannot bear high heat generated by burning semi coke and is easy to damage, the heat exchange efficiency of the boiler is low, and a hearth of the boiler is fixed in a boiler body, so that the heat conduction efficiency is low.

The coal-fired boiler is in long-term operation in-process, and the most main part that is heated and heat exchange takes place just is located the combustion chamber of boiler, because the incrustation scale of burning production can cause the water pipe to block up to dry combustion method can make the combustion chamber burn out drowned, consequently requires highly to the combustion chamber of boiler.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the problems of low heat extraction efficiency and easy damage of the fire grate of the built-in fixed hearth and the cast iron furnace in the existing boiler.

In order to achieve the purpose, the utility model provides a semi-coke boiler, which comprises a boiler body, a boiler furnace arranged in the boiler body, a hearth and a fire grate arranged in the boiler body, wherein the hearth and the fire grate are sequentially arranged below the boiler furnace from top to bottom, and the hearth is detachably and movably connected with the boiler body;

the fire grate is a movable water pipe detachable fire grate made of seamless steel pipes;

the fire grate comprises a water inlet end, a water outlet end and a plurality of movable water pipes which are arranged between the water inlet end and the water outlet end in parallel;

the water inlet end and the water outlet end are respectively provided with a water inlet pipe section and a water outlet pipe section;

the water inlet pipe section and the water outlet pipe section are respectively and fixedly connected with the furnace body through flanges and further communicated with water in an interlayer contained between the furnace body and the furnace pipe;

the movable water pipe is respectively communicated with the cavities of the water inlet end and the water outlet end.

The water inlet pipe section is communicated with a cavity between the furnace pipe and the hearth through a first elbow flange and a water pipe, and the cavity is communicated with the interlayer through a second elbow flange;

and the water outlet pipe section is communicated with the bottom of the interlayer through a third elbow flange.

The utility model has the advantages as follows:

1. utilize second elbow flange and this body coupling of boiler, separate original furnace from the boiler, become detachable movable furnace, convenient to detach and maintenance avoid current unable dismantlement and the defect of in time maintaining to the life of boiler has been improved greatly.

2. The detachable grate with movable water pipes is adopted in the product, a cast iron grate is replaced by seamless steel pipes, then the detachable grate is adopted, and the bolt flange is connected to a semi-coke boiler body, namely a boiler body, so that a water circulation system is formed between the boiler body and the semi-coke boiler body.

3. At present, the original cast iron grate of the boiler bears low heat, the thermal efficiency of the boiler is low, the product can be used for solving the problem that the original cast iron grate cannot bear high heat generated by burning semi coke, and the detachable grate is connected with the boiler body to form a water circulation system so as to improve the thermal efficiency of the boiler.

The present invention will be described in detail with reference to the accompanying drawings and examples.

Detailed Description

In order to overcome the problems of short service life of a hearth, easy damage of a fire grate and low thermal efficiency of the existing boiler, the embodiment provides the semi-coke boiler shown in the figures 1 and 2, which comprises a boiler body 1, a boiler liner 2 arranged in the boiler body 1, a hearth 3 arranged in the boiler body 1 and a fire grate 4, wherein the hearth 3 and the fire grate 4 are sequentially arranged below the boiler liner 2 from top to bottom.

As shown in fig. 3, the removable grate with movable water pipes made of seamless steel pipes comprises a water inlet end 5, a water outlet end 6 and a plurality of movable water pipes 7 arranged between the water inlet end 5 and the water outlet end 6 in parallel; the water inlet end 5 and the water outlet end 6 are respectively provided with a water inlet pipe section 8 and a water outlet pipe section 9; the water inlet pipe section 8 and the water outlet pipe section 9 are respectively fixedly connected with the furnace body 1 through flanges and further communicated with water in an interlayer 10 contained between the furnace body 1 and the furnace pipe 2; the specific connection structure is shown in fig. 2: the water inlet pipe section 8 is communicated with a cavity 13 between the furnace pipe 2 and the hearth 3 through a first elbow flange 11 and a water pipe 12, and the cavity 13 is communicated with the interlayer 10 through a second elbow flange 14; the water outlet pipe section 9 is communicated with the bottom of the interlayer 10 through a third elbow flange 15, so that a water circulation system is formed between the grate and the boiler body, namely the boiler body 10, the problem that the original cast iron grate cannot bear high heat generated by burning of semi coke (mainly because water flowing through the cavity absorbs heat at a hearth to generate a cooling effect) is solved, and the detachable grate is connected with the boiler body to form the water circulation system so as to improve the heat efficiency of the boiler. Wherein, the movable water pipe 7 is respectively communicated with the cavities of the water inlet end 5 and the water outlet end 6, thereby realizing the communication with the water inlet pipe section 8 and the water outlet pipe section 9.

Through the improvement of the embodiment, the boiler using the semi coke as the fuel is realized, the primary combustion is carried out in the movable combustion chamber, namely the hearth, the secondary combustion is carried out in the movable water pipe grate, and the heat efficiency is improved by the water circulation system.
