Filter

Abstract

The invention relates to field of water treatment, in particular to a filter. The filter comprises a tank body, a water inlet pipe, a water outlet pipe, a filtering device and a blow-off pipe, wherein the water inlet pipe is communicated with the inside of the tank body; a part of the water outlet pipe is inserted into the tank body; the filtering device is externally connected to the water outlet pipe inside the tank body, is communicated with the water outlet pipe, and is used for filtering water to be treated and draining the filtered water out of the water outlet pipe; and the blow-off pipe is communicated with the bottom of the tank body, and is used for discharging impurities left after the water to be treated is filtered. In the filter provided by the invention, the water outlet pipe inserted into the tank body is provided with the filtering device, so that the water to be treated is drained through the water outlet pipe after being filtered by the filtering device, and residual impurities left after filtering can be discharged along the blow-off pipe at the bottom of the tank body. Due to the adoption of the filter, the problems of blocking of pipelines and damage to partsin high-temperature combustion furnace equipment caused by directly repeatedly using the water to be treated without filtering are solved, capitals consumed by maintaining equipment are saved, and the utilization ratio and production efficiency of the high-temperature combustion furnace equipment are increased.

Description

Technical field [0001] The invention relates to the field of water treatment, in particular to a filter. Background technique [0002] In the current prior art, the high-temperature incinerator realizes gasification of coal through high temperature, and the temperature of gasified coal is very high. Therefore, water is required to cool the high-temperature gasified coal. Because there are still impurity components in the gasified coal that are not completely gasified, after the water contacts the gasified coal, some impurities will be mixed into the water, and the water is recycled, and the water doped with impurities will continue to be recycled into the high temperature incineration The furnace continues to cool the gasified coal, and then it will carry more impurities and continue to circulate. After reciprocating many times, due to the excessive impurities carried, some impurities will be deposited in the pipeline through which the circulating water flows. When the impurities...

Problems solved by technology

Since there are impurities in the gasification coal that have not been completely gasified, after the water is in contact with the gasification coal, some impurities will be mixed into the water, and the water is recycled, and the water mixed with impurities will continue to circulate into high-temperature incineration The furnace continues to cool the gasified coal, and then it will carry more impurities to continue to circulate. After many times, due to the excessive impurities carried, some impurities will be deposited in the pipeline through which the circulating water flows. When the impurities are deposited to a certain amount Sometimes, the pipeline in the equipment will be blocked, and even the internal parts of the equipment will be damaged.

For high-cost equipment, cleaning equipment and replacing parts require high capital investment, which makes maintenance inconvenient and delays production
