Description

A spray water circulation treatment device for an exhaust gas treatment system

technical field

The utility model mainly relates to the technical field of waste gas treatment, in particular to the technical field of spray water circulation treatment of a waste gas treatment system.

Background technique

At present, in order to protect the environment and people's health, the country strictly sets the emission standards of industrial waste gas, so industrial waste gas needs to be treated before discharge, and most of the industrial waste gas has a relatively high temperature. In order to meet the national environmental protection emission standards, industrial The exhaust gas treatment device will be equipped with a spraying device, which will extract the water in the spray water tank to spray and cool the exhaust gas in the exhaust gas discharge pipe, and in order to save water resources, the water after spraying the exhaust gas It will be collected into the buffer tank, and often will be drawn back to the spray water tank for recycling through the spray water circulation pipe, but the existing industrial waste gas often contains solid debris, so the water after spraying the waste gas will also contain solid debris , And then it is easy to cause the spray water circulation pipe to block, the equipment failure rate is high, and the efficiency is low.

Contents of the invention

The utility model provides a spray water circulation processing device of a waste gas treatment system. The device has a simple structure and can effectively separate impurities in water after spraying waste gas, solves the problem that the spray water circulation pipe is easily blocked, and reduces equipment failures. incidence and improve efficiency.

The technical scheme that the utility model adopts is:

A spray water circulation treatment device for an exhaust gas treatment system, comprising an exhaust gas discharge pipeline, a spray device provided with a spray water tank and connected to the exhaust gas discharge pipeline, a buffer tank connected to the bottom of the exhaust gas discharge pipeline, and an inlet through a pump The water pipe is connected to the filter with the buffer tank, and the debris tank is connected to the sewage outlet of the filter through the debris collection pipe, and the outlet of the filter is communicated with the spray water tank through the spray water circulation pipe.

In the spraying water circulation treatment device, the spraying device extracts the water in the spraying water tank to spray and cool the exhaust gas in the exhaust gas discharge pipeline, and the buffer tank communicates with the bottom of the exhaust gas discharge pipeline to collect the water after spraying the exhaust gas, and The spray water circulation treatment device is provided with a filter connected with the buffer tank, the filter is connected with the buffer tank through the suction pipe, and can extract the water in the buffer tank after spraying the waste gas to filter, so as to separate the water after spraying the waste gas. For the debris in the water, the sewage outlet of the filter is connected to the debris tank, that is, the filtered debris can be collected into the debris tank for recycling, saving resources, and the outlet of the filter is connected to the tank through the spray water circulation pipe. Spray water tank, that is, the water filtered by the filter returns to the spray water tank for recycling through the spray water circulation pipe, which will not cause blockage of the spray water circulation pipe, reduce the failure rate of equipment, and improve efficiency.

The above-mentioned filter is a self-cleaning filter, and a control electric box is electrically connected to the self-cleaning filter. The self-cleaning filter can automatically clean the filter element. When the debris in the filter element accumulates to a certain extent and the water pressure in the filter reaches the set water pressure for cleaning the filter element, the self-cleaning filter automatically cleans the filter element. Cleaning means that the slag in the filter is pumped into the slag tank through the slag collection pipe to complete the collection of slag, and the time for cleaning the filter can also be set by controlling the electric box, which is more convenient to use.

The beneficial effects brought by the utility model are:

The spray water circulation treatment device can effectively separate the slag in the water after spraying the waste gas, avoid the blockage of the spray water circulation pipe, reduce the failure rate of the equipment, improve the work efficiency, and recycle the slag in the waste gas processing, saving resources.

detailed description

Existing common exhaust gas treatment systems include spray devices, washing boxes, centrifugal fans, deoiling towers and electrochemical purification devices for exhaust gas to pass through in sequence, and finally the treated exhaust gas is discharged through the chimney. A waste gas treatment system in this embodiment The spray water circulation treatment device of the system can circulate the spray water in the spray device in the exhaust gas treatment system. As shown in Figure 1, the spray water circulation treatment device includes an exhaust gas discharge pipeline 3, a spray water tank 2 and connected to the spray device 1 of the exhaust gas discharge pipeline 3, the buffer tank 4 connected to the bottom of the exhaust gas discharge pipeline 3, and also includes a filter whose inlet is communicated with the buffer tank 4 through the suction pipe 5, and through the debris collection pipeline 8 The debris tank 9 connected to the sewage outlet of the filter, the outlet of the filter communicates with the spray water tank 2 through the spray water circulation pipe 7 .

In the spray water circulation treatment device, the spray device 1 extracts the water in the spray water tank 2 to spray and cool the waste gas in the waste gas discharge pipe 3, and the buffer tank 4 communicates with the bottom of the waste gas discharge pipe 3 to collect the spray waste gas and the spray water circulation treatment device is provided with a filter communicated with the buffer tank 4, the filter is communicated with the buffer tank 4 through the suction pipe 5, and the water after spraying the waste gas in the buffer tank 4 can be extracted Filter to separate the debris in the water after spraying the waste gas, the sewage outlet of the filter is connected to the debris tank 9, that is, the filtered debris can be collected in the debris tank 9 for recycling, saving resources, and The outlet of the filter is connected to the spray water tank 2 through the spray water circulation pipe 7, that is, the water filtered by the filter returns to the spray water tank 2 for recycling through the spray water circulation pipe 7, without causing damage to the spray water circulation pipe 7.
