Description

Novel hot-blast furnace combustion valve body blowdown device

Technical Field

The utility model belongs to the technical field of blast furnace production and specifically relates to a novel hot-blast furnace combustion valve body blowdown device.

Background

At present, blast furnace production utilizes TRT gas to generate electricity, but the temperature of the TRT gas is lower and is about 30-50 ℃, the gas used by a burning furnace of a hot blast furnace is the TRT gas, the temperature of the gas is too low, the moisture in the gas is large, and the gas is easy to condense and accumulate water at a valve body of a gas burning valve. Due to the limited space position of the blast furnace, the hot blast furnace system does not have a gas preheating system at an enough position, the TRT gas cannot be preheated, and the gas contains corrosive gases such as chloride ions and condensed water, so that the valve body and the sealing surface of the gas combustion valve are easily corroded; in addition, impurities contained in the coal gas and condensed water are mixed to easily form dirt and are accumulated at the bottom of the valve, so that a flashboard of a combustion valve is not in place during air supply, the coal gas combustion valve is blown out, the coal gas explosion accident caused by mixing of air and coal gas is caused, and great potential safety hazard exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel hot-blast furnace combustion valve body blowdown device is provided, solve the big problem that causes serious corrosion of coal gas moisture to combustion valve body and sealed face, extension valve life reduces the potential safety production hazard.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a novel hot-blast furnace combustion valve body blowdown device, irritates including setting up respectively in a plurality of accumulations of each gas combustion valve bottom drain of hot-blast furnace, the lower extreme of long-pending dirty jar is provided with the manual gate valve that is used for controlling comdenstion water and dirt in the long-pending dirty jar, manual gate valve below is provided with regularly automatic drainer, automatic drainer is regularly with comdenstion water and dirt discharge to the recovery jar that automatic drainer below set up.

The utility model discloses technical scheme's further improvement lies in: the accumulated dirt tank is a cylindrical tank body, and two ports of the accumulated dirt tank are contracted and reduced and are respectively connected with a sewage outlet at the bottom of the combustion valve and the manual gate valve.

The utility model discloses technical scheme's further improvement lies in: and a sight glass is arranged on the dirt accumulation tank.

Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:

the utility model discloses an increase at coal gas combustion valve bottom and amass the jar, make coal gas comdenstion water and dirt enter amass the jar, install manual valve and timing drainage device in amass a jar lower part, regularly carry out the blowdown clearance to amass the jar in the process of burning out the stove, effectively enlarge coal gas combustion valve lower part space, avoid comdenstion water and dirt to amass, the valve that causes closes not tight and leads to the production of coal gas accident, be provided with the sight glass on the amass jar simultaneously, be convenient for observe the interior sewage condition of amass jar;

the utility model discloses can improve equipment safe operation coefficient, prevent the emergence of production accident, can prolong the life of valve simultaneously.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a partial enlarged view of the present invention;

the device comprises a gas combustion valve 1, a dirt accumulation tank 2, a manual gate valve 3, an automatic drainer 4 and a recovery tank 5.

Detailed Description

The present invention will be described in further detail with reference to the following examples:

as shown in fig. 1-2, a novel blowoff device for a combustion valve body of a hot blast stove comprises a plurality of accumulated dirt tanks 2 respectively arranged at the blow-off port at the bottom of each gas combustion valve of the hot blast stove, wherein each accumulated dirt tank 2 is a cylindrical tank body, the two end ports of each accumulated dirt tank 2 are contracted and reduced according to the size of the blow-off port at the bottom of each gas combustion valve of the hot blast stove, the lower end of each accumulated dirt tank 2 is provided with a manual gate valve 3 for controlling the size of condensed water, dirt and gas discharge in each accumulated dirt tank, and each accumulated dirt tank 2 is respectively connected with the blow-off port at the bottom of each combustion valve 1 and the manual gate valve. The accumulated sewage tank 2 is provided with a sight glass, so that the condition of sewage in the accumulated sewage tank 2 can be observed conveniently. The automatic timing drainer 4 is arranged below the manual gate valve 3, the automatic drainer 4 is debugged, the setting of pulse duration and frequency is adjusted, dirt and condensate water in the dirt accumulation tank 2 are discharged at fixed time and fixed point, the dirt and the condensate water in the dirt accumulation tank 2 are discharged to the recovery tank 5, and the dirt in the recovery tank 5 is cleaned regularly.

The utility model discloses an increase long-pending dirty jar 2 in 1 bottom of gas combustion valve, make coal gas comdenstion water and dirt get into long-pending dirty jar 2, at long-pending dirty jar 2 lower part installation hand valve 3 and timing drainer 4, burn stove in-process and regularly carry out the blowdown clearance to long-pending dirty jar 2, effectively enlarge 1 lower part space of gas combustion valve, avoid comdenstion water and dirt to deposit, thereby the valve that causes closes not tight production that leads to the coal gas accident, the equipment safe operation coefficient has been improved, prevent the emergence of production accident, can prolong the life of valve simultaneously.
