Description

Flue gas purification system of SBI test furnace

Technical Field

The utility model relates to a SBI test furnace gas cleaning system belongs to the experimental gas cleaning of monomer burning and handles technical field.

Background

The SBI test is a monomer combustion test which is an important method for detecting the combustion performance of the building material. An SBI test furnace is an important device in a fireproof material laboratory, and strict control requirements are provided for smoke exhaust air speed, air quantity, combustion temperature and the like in the test process; different test materials have different components, and the smoke pollution components generated in the experiment have great difference, so that the smoke not only influences the health of operators, but also can cause serious pollution to the environment if directly discharged to the environment.

The traditional flue gas treatment method comprises a dust removal filtering process, a wet washing process or an active carbon filtering process, and the methods can only remove particulate matters, hydrogen chloride, hydrogen fluoride and other acidic substances in the flue gas, can not effectively remove dioxin and other pollutants in the flue gas at the same time, and can not effectively remove the odor problem of the flue gas, and the removal treatment of the dioxin and the odor problem is a technical problem which is urgently needed to be solved in the SBI test at the present stage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an SBI test furnace gas cleaning system can effectively collect the flue gas and carry out the effective processing to each item pollution of flue gas.

The utility model adopts the technical scheme as follows:

a flue gas purification system of an SBI test furnace comprises a filter, a secondary combustion furnace, a quench tower, a bag-type dust remover, a fan and a chimney which are sequentially connected through pipelines, wherein an active carbon injection device and a lime powder feeder are arranged on the pipeline between the quench tower and the bag-type dust remover,

the filter is connected with the SBI test furnace through a flue gas collecting pipeline.

Furthermore, the number of the SBI test furnaces is 3 or more than 3, and a flame-retardant valve is arranged on a flue gas collecting pipeline between each SBI test furnace and the filter.

Preferably, the secondary combustion furnace is a direct combustion furnace.

Preferably, the filter is an activated carbon box.

Preferably, the pipeline and the flue gas collecting pipeline are both stainless steel pipes.

The utility model discloses a theory of operation is, SBI test furnace is at experimental in-process, and the flue gas passes through the flue gas collecting pipe and is received the filter by airtight collection, gets into after the filter is handled that after secondary combustion furnace burns stench and dioxin in the effective processing flue gas, then through the rapid cooling, spout active carbon and lime powder and further adsorb and purify the flue gas, at last through bag collector dust removal filtration back, gas after will handling through the fan is discharged from the chimney.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. adopt the utility model discloses, the flue gas can obtain airtight collection, again can the effective processing each item pollution index in the flue gas, especially can get rid of other pollutants such as dioxin and stench in the flue gas.

2. The utility model can be matched with a human-computer interface and PLC control, and can be started and stopped by one key, thereby realizing automatic operation; through the control of fire-retardant valve, can satisfy single or many SBI test furnace and experiment simultaneously, do not have the interact between the SBI test furnace, improve gas cleaning equipment's intellectuality.

3. The utility model discloses can promote flue gas purification efficiency, under the various different test material circumstances, each item pollution index (flue gas blackness, particulate matter, hydrogen chloride, hydrogen fluoride, nitrogen oxide, sulfur dioxide, dioxin, foul smell etc.) homoenergetic of flue gas is up to standard to be discharged, has reduced the pollution to the environment.

4. The utility model discloses set up fire-retardant valve on the pipeline, high temperature equipment and pipeline can take thermal-insulated heat preservation measure simultaneously, improve entire system's security performance.

5. The utility model discloses an integrated design of integral type, the installation is maintained simply to can effectively reduce area and workspace.

6. The utility model discloses a pipeline and core component all adopt the corrosion-resistant purpose-built nonrust steel pipe of thick wall, can improve whole gas cleaning system's life.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. The objects, aspects and advantages of the present invention will become more apparent from the following description. It should be understood that the described embodiments are presently preferred, but not all embodiments of the invention.

Example 1

Referring to fig. 1, the flue gas purification system of the SBI test furnace comprises a filter 3, a secondary combustion furnace 4, a quench tower 5, a bag-type dust remover 6, a fan 7 and a chimney 8 which are sequentially connected through a pipeline 2a, wherein an activated carbon injection device 9 and a lime powder feeder 10 are installed on the pipeline between the quench tower 5 and the bag-type dust remover 6. The SBI test furnace 1 is connected with a filter 3 of the whole flue gas purification system through a flue gas collecting pipeline 2. The secondary combustion furnace 4 is a direct combustion furnace; the filter 3 is an activated carbon box; the pipeline 2 and the flue gas collecting pipeline 2 are preferably made of stainless steel pipes.
