Description

Technical Field

[0001] This utility model relates to the field of gas-fired steam generator technology, and specifically to an automatic sewage discharge device for a gas-fired steam generator. Background Technology

[0002] A gas-fired steam generator, also known as a gas-fired steam boiler, is a device that uses gas (such as natural gas or liquefied petroleum gas) as fuel to generate heat energy through combustion, causing water to evaporate rapidly and form steam. The core of a gas-fired steam generator is the burner. When the gas enters the burner, it is ignited by an ignition device and burns in the combustion chamber. The high-temperature flame and flue gas produced by combustion transfer heat to the heat exchanger, thereby heating the feedwater to produce steam.

[0003] During the operation of a gas-fired steam generator, impurities gradually accumulate in the water. These impurities mainly originate from the feed water. As steam is continuously generated, the concentration of impurities in the water increases relatively. If these impurities are not discharged in a timely manner or are not discharged sufficiently, they will have many adverse effects on the performance and safe operation of the steam generator, such as causing scaling and corrosion. The wastewater discharged from the gas-fired steam generator still has certain recycling value; direct discharge is wasteful and does not meet environmental protection requirements. Therefore, those skilled in the art have provided an automatic wastewater discharge device for gas-fired steam generators to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic sewage discharge device for a gas-fired steam generator, solving the following technical problems:

[0005] How to improve the adequacy of wastewater discharge from gas-fired steam generators and achieve the recycling of wastewater discharged from gas-fired steam generators.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An automatic sewage discharge device for a gas-fired steam generator is applied to the gas-fired steam generator. It includes a filter assembly, which is connected to a temporary storage tank via a liquid passage pipe. A liquid outlet valve is fixed to the lower side of the temporary storage tank.

[0008] The filter assembly includes a housing, with an inlet chamber and a drain chamber respectively located on the upper and lower sides inside the housing. A filter element is detachably connected between the inlet chamber and the drain chamber. A top cover is fixedly connected to the upper end of the housing by bolts.

The liquid inlet end of the liquid pump 1 is fixedly connected to a liquid inlet pipe 1 that is fixedly connected to the lower end of the gas steam generator water tank.

[0010] Furthermore, it also includes a flushing assembly for flushing the water tank of the gas-fired steam generator and assisting in sewage discharge;

[0011] Furthermore, the flushing assembly includes a second liquid pump, the inlet of which is connected to a temporary storage tank, and the outlet of which is fixedly connected to a fourth liquid pipe. The fourth liquid pipe is connected to a flushing pipe, which is fixedly installed inside the gas-fired steam generator and has multiple downward-sloping nozzles.

[0012] Furthermore, there are two flushing pipes, which are symmetrically arranged on both sides of the interior of the gas steam generator, and the two flushing pipes are connected by a bend.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see the appendix Figures 1 to 4 As shown in the figure, an automatic sewage discharge device for a gas-fired steam generator is applied to a gas-fired steam generator 1. It includes a filter assembly 6, which is connected to a temporary storage tank 8 via a liquid passage pipe 7. A liquid outlet valve 9 is fixed on the lower side of the temporary storage tank 8.

[0028] The filter assembly 6 includes a housing 61. Inside the housing 61, an inlet chamber and a drain chamber are respectively located on the upper and lower sides. A filter element 62 is detachably connected between the inlet and drain chambers. A top cover 63 is bolted to the upper end of the housing 61. A liquid-passing pipe 5, communicating with the inlet chamber, is fixedly connected to one side of the housing 61. A liquid pump 4 is fixedly connected to the liquid-passing pipe 4. A liquid-passing pipe 2, fixedly connected to the lower end of the water tank of the gas-fired steam generator 1, is fixed to the inlet end of the liquid pump 4. During sewage discharge, the sewage in the water tank of the gas-fired steam generator 1 is pumped into the filter assembly 6 by the liquid pump 4. The sewage passes through the filter element 62 inside the filter assembly 6 from top to bottom. The filtered sewage is discharged into a temporary storage tank 8 through a liquid-passing pipe 7 for temporary storage. The sewage stored in the temporary storage tank 8 is filtered and can be used to generate steam again for heating, or for other purposes, such as cleaning or cooling water. This realizes the reuse of sewage from the gas-fired steam generator 1, reduces waste, and is more environmentally friendly.

[0029] The detachable connection methods of the filter element 62 include, but are not limited to, bolt connection, snap connection, and plug-in connection. The detachable filter element 62 is easy to replace and clean. When replacing, the filter element 62 can be taken out by first removing the top cover 63.

[0030] It should be noted that filter element 62 is made of stainless steel, which has a strong filtration effect, a long service life, and can effectively filter out impurities and particulate matter in sewage.

[0031] In this embodiment, a solenoid valve 3 is fixedly connected to the outer end of the liquid passage pipe 2, and a solenoid valve 11 is fixed to the outer end of the liquid passage pipe 7.

[0032] Example 2

[0033] In order to ensure that the wastewater and impurities in the gas-fired steam generator 1 can be fully discharged, and at the same time, to further utilize the filtered wastewater, this embodiment is provided.

[0034] Please see Figure 1 and Figure 3 As shown, based on Embodiment 1, this sewage discharge device further includes a flushing assembly 10, which is used to flush the water tank of the gas steam generator 1 to assist in sewage discharge.

[0035] Specifically, the flushing assembly 10 includes a second liquid pump 101. The inlet of the second liquid pump 101 is connected to the temporary storage tank 8, and the outlet is fixedly connected to a fourth liquid pipe 102. The fourth liquid pipe 102 is connected to a flushing pipe 104. The flushing pipe 104 is fixedly installed inside the gas-fired steam generator 1 and has multiple downward-sloping nozzles 105. The second liquid pump 101 pumps the filtered sewage in the temporary storage tank 8 into the flushing pipe 104, and the multiple nozzles 105 spray it into the gas-fired steam generator 1. By using the flushing of water flow, the residual sewage and impurities in the gas-fired steam generator 1 are reduced, and the adequacy of sewage discharge is further improved.

[0036] The flushing pipe 104 has two parts, which are symmetrically arranged on both sides of the inside of the gas steam generator 1. The two flushing pipes 104 are connected by a bend 106. The two flushing pipes 104 can simultaneously flush both sides of the water tank of the gas steam generator 1 during flushing, ensuring sufficient flushing. The bend 106 connecting the two flushing pipes 104 is a bend that winds around from the bottom, so that it can bypass the combustion chamber inside the gas steam generator 1.

[0037] In this embodiment, a solenoid valve 103 is fixed to the outer end of the liquid passage pipe 102. The solenoid valve 103 is used to control the opening and closing of the liquid passage pipe 102.
